## README

# react-native-use-native

A tool to use native code by JavaScript. Only some Android classes are now supported.

## Updates
Now lastest version is: 1.0.4
Since version 1.0.3, $app is an `ReactApplicationContext` class Object, `$appnative` is a `Context` class Object. But, you only use string `$appnative`. Start from version 1.0.4, you can use `$appnative`.

### Version 1.0.3 Updates
Mainly Update:
1. Since version 1.0.3, the non-basic type will return the internal name(such as `$3`) not string `Refrence Type`.
2. Support Array and List.
3. Support the Boolean values.

## Requirements
### react-native == 0.70 
The lower version and greater version is not tested.

## Installation

```sh
npm install react-native-use-native
```

## Usage
The basic is to use `useJavaStatic` method to call call static methods and use `useJava()` method to call non-static methods.  
### Method declaration
```js
useJavaStatic(className:string,methodName:string,params:any[],packageName:string=""):Promise<string>
useJava(objectName:string,methodName:string,params:any[]):Promise<string>
```
In `useJavaStatic`, when packageName=="",  the className must be the full name includes package name such as `android.widget.Toast` not `Toast`. Of Course, you can write `Toast` in className and `android.widget` in packageName. 

An example about Toast:
```js
import {useJavaStatic,useJava,$app} from 'react-native-use-native';
const toast=await useJavaStatic("android.widget.Toast","makeText",[$app,"HelloToast",0]);
await useJava(toast,"show",[]);
```
The $app refers to the ReactApplicationContext of now application. You also can directly use `useJavaNative`. Please see the source code to know more.

### use Libraries
Some classes(such as `Toast`) is packaged to JavaScript/TypeScript Classes, you can directly use these classes.
```js
import {Toast} from 'react-native-use-native';
let toast=await Toast.makeText($app,"HelloToast",Toast.LENGTH_SHORT);
await toast.show();
```

### Create Java Object
You also can create a Java Object by using `createJavaObject`.
You can use `getJavaObjectValue` to get the value of below's type:int,float,double,Integer,Float,Double and String. Else type will return the string value:Refrence Type. It only can find the object that returned in JS or created by `createJavaObject`. 

### Notes 
The Java/Android packages you want to use must be imported in Java Code.
