监听安装完成回到前台

2017-05-31

先留代码


private void registerInstalledBroadcast() {
    if (mReceiver == null) {
        mReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {

                String packageName = intent.getData().getSchemeSpecificPart();

                if (TextUtils.equals(mInfo.packageName, packageName)) {
                    launchMySelf();
                    //                        unRegisterInstalledBroadcast();
                }
            }
        };
    }

    IntentFilter filter = new IntentFilter(Intent.ACTION_PACKAGE_ADDED);
    filter.addDataScheme("package");
    this.getContext().registerReceiver(mReceiver, filter);
}

method.1
11以上支持，需要添加REORDER_TASKS权限，本质上是调整tasks的顺序

1
2
3

int taskId = ((Activity) ctx).getTaskId();
//NEED  <uses-permission android:name="android.permission.REORDER_TASKS"/>
mAm.moveTaskToFront(taskId, 0);

method.2
关键点是通过 ApplicationContext去启动


Intent it1 = new Intent(ctx.getApplicationContext(), ctx.getClass());
it1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED); //两种都可以
//            it1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP);
ctx.getApplicationContext().startActivity(it1);
