Question

我有一个COMPLETED ON BOOT服务，如果我收到短信，音乐会立即开始。

我做错了吗？

public class MyService extends Service {

final MediaPlayer mPlayer = MediaPlayer.create(getApplicationContext(), R.raw.son1);

private final BroadcastReceiver receiver = new BroadcastReceiver() {
       @Override
       public void onReceive(Context context, Intent intent) {
          String action = intent.getAction();
          if(action.equals("android.provider.Telephony.SMS_RECEIVED")){
             AudioManager mAudioManager = (AudioManager)getApplication().getSystemService(Context.AUDIO_SERVICE);
             mAudioManager.setStreamVolume(AudioManager.STREAM_MUSIC, mAudioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC), 0);
                           mPlayer.start();
          }
       }
    };

}


<service android:name=".MyService"/>
    <receiver android:name=".AutoStart">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
        </intent-filter>
    </receiver>

Answer 1

我建议您在AndroidManifest.xml中使用android:priority="999"，如下所示，

<receiver
        android:name="com.application.reciever.SMSReceiver"
        class="com.application.reciever.SMSReceiver" android:exported="true">
        <intent-filter android:priority="999" >
            <action android:name="android.provider.Telephony.SMS_RECEIVED" />
        </intent-filter>
</receiver>

这样您的应用程序就可以获得SMS Receive事件的优先权。

public class SMSReceiver extends BroadcastReceiver 
{
      @Override
      public void onReceive(Context mContext, Intent intent) 
      {
          // Your code to play music
      } 
}

Answer 2

您可能会错过接收SMS_RECEIVED广播的权限。尝试添加到您的清单：

<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>

收到短信时无法启动我的服务
