SystemAPP 静默安装

本文介绍: 【代码】Sy ste mAPP 静默安装。

注册监听

&lt;receiver
    android:name="InstallResultReceiver"
    android:enabled="true"
    android:exported="true"&gt;
    <intent-filter&gt;
        <action android:name="android.content.pm.extra.STATUS"/&gt;
    </intent-filter>

</receiver>

public class InstallResultReceiver extends BroadcastReceiver {
    public final String TAG = "carden" + InstallResultReceiver.class.getSimpleName();

    public InstallResultReceiver() {
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d(TAG, "收到安装反馈广播了");
        if (intent != null) {
            final int status = intent.getIntExtra(PackageInstaller.EXTRA_STATUS,
                    PackageInstaller.STATUS_FAILURE);
            Log.d(TAG, "收到安装反馈广播了--"+status);
            if (status == PackageInstaller.STATUS_SUCCESS) {
                // success
                int requestCode=intent.getIntExtra("flag",0);
                if (requestCode==1){
                    Log.d(TAG,"静默安装成功");
                }else if (requestCode==2){
                    Log.d(TAG,"静默卸载成功");
                }
                Log.d(TAG, "APP Install Success!");
            } else {
                String msg = intent.getStringExtra(PackageInstaller.EXTRA_STATUS_MESSAGE);
                Log.e(TAG, "Install FAILURE status_massage" + msg);
            }
        }

    }
}

2，安装，路径根据自己授权动态填写，我是写死的
