Question

收到短信时，我无法捕捉到意图。以下是我的服务代码。我能够抓住“Intent.ACTION_SCREEN_ON”和“Intent.ACTION_SCREEN_OFF”，但我无法抓住SMS_RECEIVED意图“android.provider.Telephony.SMS_RECEIVED”。

真诚地感谢我在这里做错了什么提示吗？

public class SmsCatcher extends Service{

BroadcastReceiver myBroadcast = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {

        Log.i("myBroadcast SmsCatcher", "Entered onReceive method");
        if(intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
            Log.i("myBroadcast SmsCatcher", "Caught SCREEN_OFF");
        }
        if(intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
            Log.i("myBroadcast SmsCatcher", "Caught SCREEN_ON");
        }

        if(intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")) {
            Log.i("myBroadcast SmsCatcher", "SMS_RECEIVED");
        }
    }
};

@Override
public IBinder onBind(Intent intent) {
    return null;
}

@Override
public void onCreate() {
    super.onCreate();
    Log.i("neil SmsCatcher", "Entered onCreate() in 'SmsCatcher extends Service'");
    Toast.makeText(this, "Entered onCreate() in 'SmsCatcher extends Service'", Toast.LENGTH_LONG).show();

    registerReceiver(myBroadcast, new IntentFilter(Intent.ACTION_SCREEN_ON));
    registerReceiver(myBroadcast, new IntentFilter(Intent.ACTION_SCREEN_OFF));

}

@Override
public void onDestroy() {
    super.onDestroy();

    Log.i("neil SmsCatcher", "Entered onDestroy() in 'SmsCatcher extends Service'");
    Toast.makeText(this, "Entered onDestroy() in 'SmsCatcher extends Service'", Toast.LENGTH_LONG).show();
}


}

更新1 ：从我正在进行的调试中添加更多信息：我使用App Internal Broadcasts Monitor看到收到短信时有广播，我什么都看不到，非常奇怪。可能是什么原因？我安装了其他短信应用（环聊，AT＆amp; T信息） - 这些无法抑制广播吗？

更新2：发现问题，但不知道如何解决 我卸载了Google Hangouts (replaces Talk)应用程序并且工作正常！围绕这个解决方案吗？（我应该根据stackoverflow规则打开一个单独的线程吗？）

更新3：找到ROOTCAUSE （当然有下面的帮助，谢谢）事实证明，由于新的Google Hangouts App，我需要setPriority(int)。我在Enabling SMS support in Hangouts 2.0 breaks the BroadcastReceiver of SMS_RECEIVED in my app

找到了解决方案

Answer 1

您需要注册android.provider.Telephony.SMS_RECEIVED意图过滤器，只有在您注册后才能检查onRecive中的意图

    IntentFilter filter = new IntentFilter(android.provider.Telephony.SMS_RECEIVED);
this.registerReceiver(myBroadcastReceiver, filter);

更新问题： 事实证明，Google Hangouts App会在收到短信后立即中止短信广播，因此禁用环聊2.0中的短信支持可能会解决问题。

Answer 2

您没有注册intent-filter：

@Override
public void onCreate() {
    // ..
    registerReceiver(myBroadcast, new IntentFilter(Intent.ACTION_SCREEN_ON));
    registerReceiver(myBroadcast, new IntentFilter(Intent.ACTION_SCREEN_OFF));
    registerReceiver(myBroadcast, new IntentFilter("android.provider.Telephony.SMS_RECEIVED")); // missing in your code
}

请在android.permission.RECEIVE_SMS中查看AndroidManifest.xml的权限。

无法捕获使用android.provider.Telephony.SMS_RECEIVED收到的短信
