Question

我尝试创建在接收短信时运行服务的简单应用。我写了所有的代码，我仍然看不到任何在短信接收上运行的服务。

代码

服务

public class MainService extends Service {

@Override
 public IBinder onBind(Intent arg0) {
    return null;
  }


  @Override
  public void onCreate() {

     Toast.makeText(this, "onCreate", Toast.LENGTH_SHORT).show();

     super.onCreate();

     }

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

@Override
public int onStartCommand(Intent intent, int flags, int startId) {

Toast.makeText(this, "onStartCommand", Toast.LENGTH_SHORT).show();

return START_STICKY;
  }
}

BroadcastReceiver类

public class SmsReceiver extends BroadcastReceiver {
    private static final String ACTION = "android.provider.Telephony.SMS_RECEIVED";


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


         context.startService(new Intent(context, MainService.class));

          // TODO - complete the sms analyze
    }
}

AndroidManifest

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


 <application
     android:allowBackup="true"
     android:icon="@mipmap/ic_launcher"
     android:label="@string/app_name"
     android:supportsRtl="true"
     android:theme="@style/AppTheme">



<service android:name=".MainService"/>

<receiver android:name=".SmsReceiver">
    <intent-filter>
        <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
    </intent-filter>
</receiver>

I also suffered this such issue earlier. I solved the same by using the flag android:enabled="true".

<receiver android:name=".SmsReceiver" android:enabled="true"
      android:priority="2000000" >

    <intent-filter>

        <action android:name="android.provider.Telephony.SMS_RECEIVED"/>

    </intent-filter>

</receiver>

实际上默认会启用它。我不知道以后会如何改变。请参阅文档http://developer.android.com/guide/topics/manifest/receiver-element.html

否则你可以再做一件关于优先考虑的事情。你能否使用大于1000的优先级。示例： - android：priority =＆＃34; 2000000＆＃34;。

在您的Android设备中，您拥有具有更高优先级接收器的短信应用程序。当他们到达时他们可能阻止短信。

为什么我的服务没有运行？
