你好
我想检查我的服务是否正在运行,如果服务正在运行,什么也不做。
但如果服务没有运行,请重新启动服务。
所以我做这样的事情。
In Manifest.xml
<receiver android:name="com.varma.android.aws.receiver.Receiver">
<intent-filter>
<action android:name="android.intent.action.SCREEN_ON" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.SCREEN_OFF" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
Receiver.java
public class Receiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Log.i("aws", "Received...");
if(isMyServiceRunning(context)) {
Log.v("aws", "Yeah, it's running, no need to restart service");
}
else {
Log.v("aws", "Not running, restarting service");
Intent intent1 = new Intent(context, Service.class);
context.startService(intent1);
}
}
private boolean isMyServiceRunning(Context context) {
ActivityManager manager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
if (Service.class.getName().equals(service.service.getClassName())) {
return true;
}
}
return false;
}
}
但是当我开/关屏幕时什么都没有发生
我究竟做错了什么?
