广播接收器未接收到意图

所以现在我已经在清单文件中声明了我的broastcastrecever…

   <receiver android:name=".MyReceiver">
    <intent-filter>
        <action android:name="android.intent.action.CALL_BUTTON" />
    </intent-filter>
   </receiver>

当按下呼叫按钮时,我想知道它的意图。

这是我的密码…

 public class MyReceiver extends BroadcastReceiver {

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

         Toast.makeText(context, "intent received", Toast.LENGTH_LONG);

         if(intent.getAction().equals("android.intent.action.CALL_BUTTON")) {
             Toast.makeText(context, "call button pressed", Toast.LENGTH_LONG);
         }

     }

 }

但是,当我按下呼叫按钮时,我看不到祝酒词。我错过什么了吗?

这是使用这个问题的答案的延续…
