BroadcastReceiver如何启动新意图

public class MyBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if (action.equals("my_action")) {
            // 启动新意图
            Intent newIntent = new Intent(this, MyNewActivity.class);
            newIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(newIntent);
        }
    }
}
