android-service

In my preference screen, I want to start a service to download files from the internet when one of the preference is being clicked. If the service is already running (downloading files), then the service should be stopped (cancel download). public class Setting extends PreferenceActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); downloadPref.setOnPreferenceClickListener(new OnPreferenceClickListener() { @Override public boolean onPreferenceClick(Preference pref) { if (DownloadService.isRunning) { Setting.this.stopService(new Intent

My issue might be blatent misunderstanding of services and my use of them, or a poss conflict with other apps. When I start a specific activity, I start two background services - location tracking to give distance travelled, and elapsed timer, both of which are passed to the activity with a BroadcastReceiver . I initiate each service with a Long through the Intent object from my primary Activity : if (!Utils.isServiceRunning(this, TrackService.class)) { Intent i = new Intent(this, TrackService.class); i.putExtra("SUB_ID", submissionID); startService(i); } And I use the following code to detect

Is there a way to start an Android Service defined in another package without using the Intent-Filter tag in the manifest file? For some reason I would not be able to update the manifest file of the app that contains the Service. If you know the exact package name and service name you can create an Intent with that. The service still needs to be declared in the other manifest though. Intent intent = new Intent(); intent.setClassName("com.example.otherapplication", "com.example.otherapplication.ServiceName"); startService(intent); 来源： https://stackoverflow.com/questions/18603381/start-service

Hi I am trying to get data on background service of Android. But I am getting this error.
