General Development

Testing a Plugin during development

The simplest way to manually test a plugin during development is to create a Cordova app as usual and add the plugin with the --link option:

$ npm run cordova -- plugin add ../path/to/my/plugin/relative/to/project --link

This creates a symbolic link instead of copying the plugin files, which enables you to work on your plugin and then simply rebuild the app to use your changes.

For Windows

After adding the plugin to your project, you probably will need to install npm again npm i and afterwards you will remove platforms and plugins folder and add the platform again and build the app again.

to use your changes while develeping you will need to do following command:

$ rm -rf platforms plugins && npm run cordova -- platform add android && npm run cordova -- build android --packageType=apk

For Linux / Mac

Just rebuild the app

$ npm run cordova -- build android --packageType=apk

Install your App on a device using adb

$ adb install -r platforms/android/app/build/outputs/apk/debug/app-debug.apk

Debugging - Logging

For logging what is going on the device start logging with following command

adb logcat > ./log.txt https://ourcodeworld.com/articles/read/295/how-to-debug-java-code-in-a-cordova-android-application-from-your-device-using-adb-in-windows
