weex集成到Android是指在Android里面加载weex页面；

1、app module下添加依赖

apply plugin: 'com.android.application'
apply from: 'https://www.mobibrw.com/wp-content/uploads/2019/11/download_jsc.gradle'
....
        ndk {
            abiFilters "armeabi-v7a", "arm64-v8a", "x86"
        }
....

dependencies {
    implementation fileTree(dir: "libs", include: ["*.jar"])
    implementation 'androidx.appcompat:appcompat:1.2.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.4'

    // 以下两个 weex_sdk 版本二选一
    //implementation 'org.apache.weex:sdk:0.28.0'
    implementation 'org.apache.weex:sdk_legacy:0.28.0'

    // fastjson
    implementation 'com.alibaba:fastjson:1.1.46.android'

    //support library dependencies


}

2、app androidManifast 添加权限

    <!--    网络-->
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    <!--    sd卡读写-->
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

3、初始化SDK

public class MyApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();

        InitConfig config = new InitConfig.Builder()
                .setHttpAdapter(new DefaultWXHttpAdapter()).build();
        WXSDKEngine.initialize(this, config);

        WXBridgeManager.updateGlobalConfig("wson_on");
        WXEnvironment.setOpenDebugLog(true);
        WXEnvironment.setApkDebugable(true);
        WXSDKEngine.addCustomOptions("appName", "WXSample");
        WXSDKEngine.addCustomOptions("appGroup", "WXApp");

    }
}

4、初始化WXSDKInstance 的 MainActivity代码

public class MainActivity extends AppCompatActivity implements IWXRenderListener {

    private WXSDKInstance wxsdkInstance;
    private Handler handler = new Handler() {
        @Override
        public void handleMessage(Message msg) {
            super.handleMessage(msg);
            /**
             * 轮询访问 WXSDKEngine 初始化状态 防止异步造成的初始化失败问题
             */
            if (msg.what == 1) {
                if (WXSDKEngine.isInitialized()) {
                    startRender();
                } else {
                    handler.sendEmptyMessageDelayed(1, 300);
                }
            }
        }
    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        wxsdkInstance = new WXSDKInstance(this);
        wxsdkInstance.registerRenderListener(this);
        if (WXSDKEngine.isInitialized()) {
            startRender();
        } else {
            handler.sendEmptyMessageDelayed(1, 300);
        }


        setContentView(R.layout.activity_main);
    }

    /**
     * WXSDKEngine 初始化成功后 开始渲染
     */
    private void startRender() {
        String pageName = "WXSample";
        /**
         * 防止空指针
         */
        if (wxsdkInstance == null) {
            wxsdkInstance = new WXSDKInstance(this);
            wxsdkInstance.registerRenderListener(this);
        }

        /**
         * 渲染远程js
         */
        String bundleUrl = "http://dotwe.org/raw/dist/38e202c16bdfefbdb88a8754f975454c.bundle.wx";
        wxsdkInstance.renderByUrl(pageName, bundleUrl, null, null, WXRenderStrategy.APPEND_ASYNC);

        /**
         * 渲染本地js
         */
        //   String bundleUrl = "index.js";
        //   wxsdkInstance.render(pageName, WXFileUtils.loadAsset(bundleUrl,this), null, null, WXRenderStrategy.APPEND_ASYNC);
    }

    /**
     * 重写生命周期方法
     */
    @Override
    protected void onResume() {
        super.onResume();
        if (wxsdkInstance != null) {
            wxsdkInstance.onActivityResume();
        }
    }

    @Override
    protected void onPause() {
        super.onPause();
        if (wxsdkInstance != null) {
            wxsdkInstance.onActivityPause();
        }
    }

    @Override
    protected void onStop() {
        super.onStop();
        if (wxsdkInstance != null) {
            wxsdkInstance.onActivityStop();
        }
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        if (wxsdkInstance != null) {
            wxsdkInstance.onActivityDestroy();
        }
    }

    @Override
    public void onViewCreated(WXSDKInstance wxsdkInstance, View view) {
        /**
         * 填充视图
         */
        setContentView(view);
    }

    @Override
    public void onRenderSuccess(WXSDKInstance wxsdkInstance, int i, int i1) {

    }

    @Override
    public void onRefreshSuccess(WXSDKInstance wxsdkInstance, int i, int i1) {

    }

    @Override
    public void onException(WXSDKInstance wxsdkInstance, String errCode, String msg) {
        Log.d("welog", "onException: " + errCode + "//" + msg);
    }
}

5、混淆处理

-keep class org.apache.weex.bridge.** { *; }
-keep class org.apache.weex.layout.** { *; }
-keep class org.apache.weex.WXSDKEngine { *; }
-keep class org.apache.weex.base.SystemMessageHandler { *; }
-dontwarn org.apache.weex.bridge.**
