Marshmallow在没有运行时许可的情况下广播接收器

Question

为什么我的广播接收器不工作？我做错了什么以及如何解决？

有类似的问题：
Broadcast Receivers not working in Android 6.0 Marshmallow
Android Broadcast receiver for call not working? (Marshmallow)

这些问题与运行时权限问题有关。在我的情况下，它不是权限问题（我猜），因为我没有使用任何权限相关的服务。我只是想创建一个简单的广播接收器 - 发送消息并将消息显示为Toast。

        <action
            android:name="MyBroadcastReceiver">

MyBroadcastReceiver

public class MyBroadcastReceiver extends BroadcastReceiver {
    private static final String TAG = "foo";

    @Override
    public void onReceive(Context context, Intent intent) {

        Toast.makeText(context, intent.getExtras().getString("mgs"), Toast.LENGTH_LONG).show();

    }
}

MainActivity

public class MainActivity extends AppCompatActivity implements View.OnClickListener {
    Button btnSend;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        //MyBroadcastReceiver br = new MyBroadcastReceiver();
        //IntentFilter intentFilter = new IntentFilter();
        //intentFilter.addAction("MyBroadcastReceiver");
        //registerReceiver(br, intentFilter); // local BR

        btnSend = (Button) findViewById(R.id.btn_send);
        btnSend.setOnClickListener(this);

    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {

            case R.id.btn_send:
                Intent intent = new Intent();
                intent.setAction("MyBroadcastReceiver");
                intent.putExtra("mgs","Just a test message");
                this.sendBroadcast(intent);
                break;
        }
    }
}
