Cordova.plugins.diagnostic NPM

Cordova diagnostic plugin

Overview

This Cordova/Phonegap plugin for iOS & Android is used to manage device settings such as Location, Bluetooth and WiFi. It enables management of run-time permissions, device hardware and core OS features.

The plugin is registered in on npm as cordova.plugins.diagnostic

I dedicate a considerable amount of my free time to developing and maintaining this Cordova plugin, along with my other Open Source software. To help ensure this plugin is kept updated, new features are added and bugfixes are implemented quickly, please donate a couple of dollars (or a little more if you can stretch) as this will help me to afford to dedicate time to its maintenance. Please consider donating if you're using this plugin in an app that makes you money, if you're being paid to make the app, if you're asking for new features or priority bug fixes.

Important notes

Minimum supported versions

Cordova CLI: cordova@9.0.0
Android platform: cordova-android@8.0.0 (recommended version cordova-android@9.0.0)
- Android version: Android 5.0 (API 21)
iOS platform: cordova-ios@5.0.0
- iOS 10.0

Note: If you need to support older OS versions, please use an older version of this plugin.

Native environment required

Note that this plugin is intended for use in a native mobile environment. It will NOT work in a browser-emulated Cordova environment, for example by running cordova serve or using the Ripple emulator.

Building for Android

In order to avoid build problems with Android, please make sure you have the latest versions of the following Android SDK components installed:

Android SDK Tools
Android SDK Platform-tools
Android SDK Build-tools
Target SDK Platform - e.g. Android 10.0 (API 29)
Google Repository

Make sure you have a supported version of the cordova-android platform installed.
- You can check if the Android platform in your Cordova project is up-to-date using cordova platform check android and if it's not, update it using cordova platform rm android && cordova platform add android@latest.
- Since cordova.plugins.diagnostic@6 the recommended Cordova Android platform version is cordova-android@9.0.0 (which includes AndroidX support).
- To use this plugin with cordova-android@8, install cordova-plugin-androidx and cordova-plugin-androidx-adapter.
Phonegap Build uses should use the latest available CLI version (listed here) by specifying using the phonegap-version tag in your config.xml.

Installation

Using the Cordova/Phonegap/Ionic CLI

$ cordova plugin add cordova.plugins.diagnostic
$ cordova plugin add cordova.plugins.diagnostic --variable ANDROIDX_VERSION=1.0.0
$ phonegap plugin add cordova.plugins.diagnostic
$ ionic cordova plugin add cordova.plugins.diagnostic

AndroidX Library

This plugin uses/depends on the AndroidX (Jetpack) libraries (these supersede the Android Support Library which is no longer used by this plugin since cordova.plugins.diagnostic@6).

This plugin pins default versions of the legacy and appcompat versions of the library in its plugin.xml however you can override these to specify different versions using the ANDROIDX_VERSION (legacy) and ANDROIDX_APPCOMPAT_VERSION variables at plugin installation time, for example:

$ cordova plugin add cordova.plugins.diagnostic --variable ANDROIDX_VERSION=1.0.0 --variable ANDROIDX_APPCOMPAT_VERSION=1.3.1

Specifying modules

Since cordova.plugins.diagnostic@4 the plugin is split into optional functional modules. The reason for this is so you can choose to install only those parts of the plugin you'll use and therefore not install redundant code/components/frameworks.

By default, all the modules will be added to your project when you install the plugin.

You can specify which modules are installed by adding a <preference> to your config.xml which specifies the modules you wish to add as a space-separated list. Module names should be capitalised.

The preference takes the form:

<preference name="cordova.plugins.diagnostic.modules" value="[list of modules]" />

For example, to explicitly include all optional modules:

<preference name="cordova.plugins.diagnostic.modules" value="LOCATION BLUETOOTH WIFI CAMERA NOTIFICATIONS MICROPHONE CONTACTS CALENDAR REMINDERS MOTION NFC EXTERNAL_STORAGE" />

To install only the core module and no optional modules, leave the preference value blank:

<preference name="cordova.plugins.diagnostic.modules" value="" />

IMPORTANT: After adding the preference to your config.xml, you'll need to uninstall then re-install the plugin to your project to apply the changes:

cordova plugin rm cordova.plugins.diagnostic --nosave && cordova plugin add cordova.plugins.diagnostic --nosave

Available modules

The following optional modules are currently supported by the plugin:

LOCATION - Android & iOS
BLUETOOTH - Android & iOS
WIFI - Android & iOS
CAMERA - Android & iOS
NOTIFICATIONS - Android & iOS
MICROPHONE - Android & iOS
CONTACTS - Android & iOS
CALENDAR - Android & iOS
REMINDERS - iOS
MOTION - iOS
NFC - Android
EXTERNAL_STORAGE - Android

IMPORTANT: It's vital that the preference be added to your config.xml before you install the plugin, otherwise the preference will not be applied and all modules will be added. This is because, due to limitations of the Cordova CLI hooks, this plugin must use the npm install process to apply the module preferences and this runs before the Cordova CLI when installing a plugin. If you change the modules specified in the preference, you'll need to uninstall then re-install the plugin to your project to apply the changes.

Reporting issues

IMPORTANT: Please read the following carefully. Failure to follow the issue template guidelines below will result in the issue being immediately closed.

Reporting a bug or problem

Before opening a bug issue, please do the following:

DO NOT open issues asking for support in using/integrating the plugin into your project
- Only open issues for suspected bugs/issues with the plugin that are generic and will affect other users
- I don't have time to offer free technical support: this is free open-source software
- Ask for help on StackOverflow, Ionic Forums, etc.
- Use the example project as a known working reference
- Any issues requesting support will be closed immediately.
DO NOT open issues related to the Ionic Typescript wrapper for this plugin
- This is owned/maintained by Ionic and is not part of this plugin
- Please raise such issues/PRs against Ionic Native instead.
- To verify an if an issue is caused by this plugin or its Typescript wrapper, please re-test using the vanilla Javascript plugin interface (without the Ionic Native wrapper).
- Any issue opened here which is obviously an Ionic Typescript wrapper issue will be closed immediately.
Read the above documentation thoroughly
Check the CHANGELOG for any breaking changes that may be causing your issue.
Check a similar issue (open or closed) does not already exist against this plugin.
- Duplicates or near-duplicates will be closed immediately.
When creating a new issue
- Choose the "Bug report" template
- Fill out the relevant sections of the template and delete irrelevant sections
- WARNING: Failure to complete the issue template will result in the issue being closed immediately.
Reproduce the issue using the example project
- This will eliminate bugs in your code or conflicts with other code as possible causes of the issue
- This will also validate your development environment using a known working codebase
- If reproducing the issue using the example project is not possible, create an isolated test project that you are able to share
Include full verbose console output when reporting build issues
- If the full console output is too large to insert directly into the Github issue, then post it on an external site such as Pastebin and link to it from the issue
- Often the details of an error causing a build failure is hidden away when building with the CLI
  - To get the full detailed console output, append the --verbose flag to CLI build commands
  - e.g. cordova build ios --verbose
- Failure to include the full console output will result in the issue being closed immediately
If the issue relates to the plugin documentation (and not the code), please of a documentation issue

Requesting a new feature

Before opening a feature request issue, please do the following:

Check the above documentation to ensure the feature you are requesting doesn't already exist
Check the list if open/closed issues to check if there's a reason that feature hasn't been included already
Ensure the feature you are requesting is actually possible to implement and generically useful to other users than yourself
Where possible, post a link to the documentation related to the feature you are requesting
Include other relevant links, e.g.
- Stack Overflow post illustrating a solution
- Code within another Github repo that illustrates a solution

Usage

The core plugin module is exposed via the global cordova.plugins.diagnostic object and it aliases all functions and properties of the other optional modules. If a function is called on the core module for an optional module which is not installed, a JS error will be raised by the core module.

Core module

Purpose: Generic and miscellaneous functionality.

Platforms: Android & iOS

Configuration name: N/A - always installed, regardless of whether the module preference key is present in config.xml.

switchToSettings()

Platforms: Android and iOS

Opens settings page for this app.

On Android, this opens the "App Info" page in the Settings app.

On iOS, this opens the app settings page in the Settings app.

cordova.plugins.diagnostic.switchToSettings(successCallback, errorCallback);

Parameters

{Function} successCallback - The callback which will be called when switch to settings is successful.
{Function} errorCallback - The callback which will be called when switch to settings encounters an error. The function is passed a single string parameter containing the error message.

Example usage

cordova.plugins.diagnostic.switchToSettings(function(){
    console.log("Successfully switched to Settings app");
}, function(error){
    console.error("The following error occurred: "+error);
});

switchToWirelessSettings()

Platforms: Android

Switches to the wireless settings page in the Settings app. Allows configuration of wireless controls such as Wi-Fi, Bluetooth and Mobile networks.

cordova.plugins.diagnostic.switchToWirelessSettings();

switchToMobileDataSettings()

Platforms: Android

Displays mobile settings to allow user to enable mobile data.

cordova.plugins.diagnostic.switchToMobileDataSettings();

permissionStatus constants

Platforms: Android and iOS

Both Android and iOS define constants for requesting and reporting the various permission states.

cordova.plugins.diagnostic.permissionStatus

Android

The following permission states are defined for Android:

NOT_REQUESTED - App has not yet requested access to this permission. App can request permission and user will be prompted to allow/deny.
DENIED_ONCE - User denied access to this permission (without checking "Never Ask Again" box). App can request permission again and user will be prompted again to allow/deny again.
DENIED_ALWAYS - User denied access to this permission and checked "Never Ask Again" box. App can never ask for permission again. The only way around this is to instruct the user to manually change the permission on the app permissions page in Settings.
GRANTED - User granted access to this permission or the device is running Android 5.x or below.

⚠ Since it's impossible to distinguish between NOT_REQUESTED and DENIED_ALWAYS using the native Android runtime permissions API (they both return the same constant value), this plugin attempts to distinguish the difference by using HTML5 local storage to keep track of which permissions have been requested since the app was first installed. On requesting a permission for the first time, an entry is put into local storage against the permission name. If the user then selects DENY_ALWAYS, the plugin uses the flag in local storage to distinguish this from NOT_REQUESTED.

Some things to watch out for:

Clearing local storage will result in this data being lost and will result in NOT_REQUESTED being returned even if the user previously chose to always deny permission.
If the relevant <uses-permission> tag is missing from the Android manifest, then the native API will return the NOT_REQUESTED/DENIED_ALWAYS constant value. Since the plugin is unable to make the native permissions request in order to show the native dialog, the plugin will always return NOT_REQUESTED.

If Android Autobackup is enabled (which it is by default ), Android does not backup app permissions after uninstall but does backup HTML5 local storage. This may lead to a permission being reported by the plugin as DENIED_ALWAYS when the actual status is NOT_REQUESTED. To avoid this you may want to disable Android Autobackup. You can do this using the cordova-custom-config plugin, for example:

<platform name="android">
    <plugin name="cordova-custom-config" version="*"/>
    <custom-preference name="android-manifest/application/@android:allowBackup" value="false" />
    <custom-preference name="android-manifest/application/@android:fullBackupContent" value="false" />
</platform>

iOS

The following permission states are defined for iOS:

NOT_REQUESTED - App has not yet requested access to this permission. App can request permission and user will be prompted to allow/deny.
DENIED_ALWAYS - User denied access to this permission. App can never ask for permission again. The only way around this is to instruct the user to manually change the permission in Settings.
RESTRICTED - Permission is unavailable and user cannot enable it. For example, when parental controls are in effect for the current user.
GRANTED - User granted access to this permission. For location permission, this indicates the user has granted access to the permission "always" (when app is both in foreground and background).
GRANTED_WHEN_IN_USE - Used only for location permission. Indicates the user has granted access to the permission "when in use" (only when the app is in the foreground).

Addtionally, for notifications permissions:

PROVISIONAL - The app is provisionally authorized to post non-interruptive user notifications.
EPHEMERAL - The app is authorized to schedule or receive notifications for a limited amount of time.

Example

if(somePermissionStatus === cordova.plugins.diagnostic.permissionStatus.GRANTED){
    // Do something
}

getPermissionAuthorizationStatus()

Platforms: Android

Returns the current authorisation status for a given permission.

Note: this is intended for Android 6 / API 23 and above. Calling on Android 5.1 / API 22 and below will always return GRANTED status as permissions are already granted at installation time.

Parameters

{Function} successCallback - function to call on successful retrieval of status. The function is passed a single string parameter which defines the current permission status
{Function} errorCallback - function to call on failure to retrieve authorisation status. The function is passed a single string parameter containing the error message.
{String} permission - permission to request authorisation status for, defined as a runtime permission constant.

Example usage

cordova.plugins.diagnostic.getPermissionAuthorizationStatus(function(status){
    switch(status){
        case cordova.plugins.diagnostic.permissionStatus.GRANTED:
            console.log("Permission granted to use the camera");
            break;
        case cordova.plugins.diagnostic.permissionStatus.NOT_REQUESTED:
            console.log("Permission to use the camera has not been requested yet");
            break;
        case cordova.plugins.diagnostic.permissionStatus.DENIED_ONCE:
            console.log("Permission denied to use the camera - ask again?");
            break;
        case cordova.plugins.diagnostic.permissionStatus.DENIED_ALWAYS:
            console.log("Permission permanently denied to use the camera - guess we won't be using it then!");
            break;

}, function(error){
    console.error("The following error occurred: "+error);
}, cordova.plugins.diagnostic.permission.CAMERA);

getPermissionsAuthorizationStatus()

Platforms: Android

Returns the current authorisation status for multiple permissions.

Note: this is intended for Android 6 / API 23 and above. Calling on Android 5.1 / API 22 and below will always return GRANTED status as permissions are already granted at installation time.

Parameters

{Function} successCallback - function to call on successful retrieval of status. The function is passed a single object parameter which defines a key/value map, where the key is the requested runtime permission, and the value is the current permission status.
{Function} errorCallback - function to call on failure to retrieve authorisation status. The function is passed a single string parameter containing the error message.
{Array} permissions - list of permissions to request authorisation statuses for, defined as runtime permission constants.

Example usage

    cordova.plugins.diagnostic.permission.ACCESS_COARSE_LOCATION
]);

isRequestingPermission()

Platforms: Android

Indicates if the plugin is currently requesting a runtime permission via the native API. Note that only one request can be made concurrently because the native API cannot handle concurrent requests, so the plugin will invoke the error callback if attempting to make more than one simultaneous request. Multiple permission requests should be grouped into a single call since the native API is setup to handle batch requests of multiple permission groups.

var isRequesting = cordova.plugins.diagnostic.isRequestingPermission();

Example usage

var isRequesting = cordova.plugins.diagnostic.isRequestingPermission();
if(!isRequesting){
    requestSomePermissions();
}else{
    cordova.plugins.diagnostic.registerPermissionRequestCompleteHandler(function(statuses){
        cordova.plugins.diagnostic.registerPermissionRequestCompleteHandler(null); // de-register handler after single call
        requestSomePermissions();
    });
}

registerPermissionRequestCompleteHandler()

Platforms: Android

Registers a function to be called when a runtime permission request has completed. Pass in a falsey value to de-register the currently registered function.

cordova.plugins.diagnostic.registerPermissionRequestCompleteHandler(successCallback);

Parameters

{Function} successCallback - The callback which will be called when a runtime permission request has completed. The function is passed a single object parameter which defines a key/value map, where the key is the permission requested (defined as a value in cordova.plugins.diagnostic.permission) and the value is the resulting authorisation status of that permission as a value in cordova.plugins.diagnostic.permissionStatus.

Example usage

function onPermissionRequestComplete(statuses){
    console.info("Permission request complete");
    for (var permission in statuses){
        switch(statuses[permission]){
            case cordova.plugins.diagnostic.permissionStatus.GRANTED:
                console.log("Permission granted to use "+permission);
                break;
            case cordova.plugins.diagnostic.permissionStatus.NOT_REQUESTED:
                console.log("Permission to use "+permission+" has not been requested yet");
                break;
            case cordova.plugins.diagnostic.permissionStatus.DENIED_ONCE:
                console.log("Permission denied to use "+permission);
                break;
            case cordova.plugins.diagnostic.permissionStatus.DENIED_ALWAYS:
                console.log("Permission permanently denied to use "+permission);
                break;
        }
    }
    cordova.plugins.diagnostic.registerPermissionRequestCompleteHandler(null); // de-register handler
}
cordova.plugins.diagnostic.registerPermissionRequestCompleteHandler(onPermissionRequestComplete);

cpuArchitecture constants

Platforms: Android and iOS

Defines constants for the various CPU architectures of the current hardware returned by getArchitecture().

cordova.plugins.diagnostic.cpuArchitecture

Android

UNKNOWN - Unknown CPU architecture
ARMv6 - ARM v6 or below (32 bit)
ARMv7 - ARM v7 (32 bit)
ARMv8 - ARM v8 (64 bit)
X86 - Intel x86 (32 bit)
X86_64 - Intel x86 (64 bit)
MIPS - MIPS (32 bit)
MIPS_64 - MIPS (64 bit)

iOS

UNKNOWN - Unknown CPU architecture
ARMv6 - ARM v6 or below (32 bit)
ARMv7 - ARM v7 (32 bit)
ARMv8 - ARM v8 (64 bit)
X86 - Intel x86 (32 bit)
X86_64 - Intel x86 (64 bit)

Example usage

See getArchitecture().

getArchitecture()

Platforms: Android and iOS

Returns the CPU architecture of the current device.

cordova.plugins.diagnostic.getArchitecture(successCallback, errorCallback);

Parameters

{Function} successCallback - The callback which will be called when operation is successful. The function is passed a single boolean parameter which indicates the location authorization status as a cpuArchitecture constant.
{Function} errorCallback - The callback which will be called when operation encounters an error. The function is passed a single string parameter containing the error message.

        console.log("Intel inside");
    }
}, function(error){
    console.error(error);
});

restart()

Platforms: Android

Restarts the application. By default, a "warm" restart will be performed in which the main Cordova activity is immediately restarted, causing the Webview instance to be recreated.

However, if the cold parameter is set to true, then the application will be "cold" restarted, meaning a system exit will be performed, causing the entire application to be restarted. This is useful if you want to fully reset the native application state but will cause the application to briefly disappear and re-appear.

Note: There is no successCallback() since if the operation is successful, the application will restart immediately before any success callback can be applied.

cordova.plugins.diagnostic.restart(errorCallback, cold);

Parameters

{Function} errorCallback - The callback which will be called when operation encounters an error. The function is passed a single string parameter containing the error message.
{Boolean} cold - if true the application will be cold restarted. Defaults to false.

Example usage

var onError = function(error){
