android-service

问题 My problem is in the question title, i'm trying to start/bind a simple service with just log in it and it's not working at all. I want to do it with Service Connexion method : public class testServiceBound extends Service { /** * PRIVATE ATTRIBUTES */ // log private static final String TAG = testServiceBound.class.getSimpleName(); private final Binder _binder = new testBinder(); @Override public void onCreate() { Log.i(TAG, "onCreate--"); super.onCreate(); } @Override public int

问题 I have a service (properly declared in the Manifest file) that upon onDestroy() schedules itself to start again one minute later via AlarmManager . However the service is not starting even though onDestroy() runs correctly. What could be wrong? The scheduling code: @Override public void onDestroy() { BroadcastReceiver br = new BroadcastReceiver() { @Override public void onReceive(Context c, Intent i) { c.startService(new Intent(c, MyService.class)); } }; registerReceiver(br, new IntentFilter(

问题 I have wrote a service to log accelerometer values in background. The idea is to register for sensor listener and write the values to storage. I have enabled the StrictMode.enableDefaults() in the MainActivity of the app (not in the service) to check if the service runs on its own thread. But it does not! I don't know what is the problem...I have this AsyncTask class that I hoped to take care of the problem but it apparently did not (this is inside the service and its execute method is called

问题 I am missing something essential or... I have two applications, one of them containing exported service with intent filter declared in AndroidManifest: <service android:name=".MyService" android:exported="true" android:permission="my.permission" > <intent-filter> <action android:name="my.service" /> </intent-filter> </service> I can successfully bind to that service from another application by using "my.service" action. But I want to start service (send command to it). If I write: Intent

问题 I have a checked button in my MainActivity. If that button is checked it should start the service but if a user unchecked the button I want to stop the service. So in uncheck condition I have written this stopService(intentname); but the problem is the service is not stopping. Here is my code snippet: Service Class public class SimpleService extends Service { String selectedAudioPath = ""; private MyThread myythread; public Intent intent; public boolean isRunning = false; long interval=30000;

问题 This question is based off of this previous question of mine: Android - Set notification to never go away I now realize that I need something to be triggered at startup to trigger the notification. From my previous question, it looks like I can take two routes. Either start a service, or use a BroadcastReceiver. I think that starting a service is a little overkill (but what do I know). I am stuck while going with the BroadcastReceiver route. It works in general, but when I take my code for a

问题 Hey I am trying to make an application that tells me when the battery is full when the phone is connected to power. I made a service and used a broadcast receiver in that to check the battery status. Whenever i connect or disconnect the phone from the power, my app crashes. The service still runs and i get the notification when battery is full. I dont know why is the app crashing again and again. Here is my code public class Srvc extends Service{ @Override public int onStartCommand(Intent

问题 My problem is that I think my service runs multiple times. The service is controlled by a switch calling a method that starts and stops the service. I have a broadcast listener inside my service and the receiver logs whenever it receives a broadcast. at first switch on, it logs two times. After switch off and on, it logs four times. public class Service1 extends Service implements DetectionListener { private static final String TAG = "ListenerService"; private final broadcastReceiver1

问题 I am sending data from text file to server using service code given below. It sends data line by line to server. I want the service to run in background continuously.For this I have written asyncTask. But it sends all data once and then stops. public class BackgroundService extends Service { private static final String TAG = "BackgroundService"; String line=null; Context mContext = null; File file;RandomAccessFile in = null; StringEntity se ; HttpEntity entity=null; final static int SERVICE

问题 I use BroadcastReceiver of ACTION_BATTERY_CHANGED to get an event every time the battery is 50%. I can't declare ACTION_BATTERY_CHANGED in manifest, so I declared the BroadcastReceiver in a Service (START_STICKY). But, when I remove the app from recent apps screen the BroadcastReceiver stops getting battery change events. How can I keep it in background? *In many apps that show battery percent in status bar, the percent is updated while the app is closed. How? 回答1: You really cannot do what
