Short answer to the subject line:
private boolean isMyServiceRunning() {
ActivityManager manager = (ActivityManager)
getSystemService(this.ACTIVITY_SERVICE);
for (RunningServiceInfo service :
manager.getRunningServices(Integer.MAX_VALUE)) {
if
("com.gabriloware.notifier.voicemail.VoiceMailNotifierService".equals(service.service.getClassName()))
{
return true;
}
}
return false;
}
to elaborate a bit, my app will start the service at bootup if it is
configured to do so. The associated activity has a checkbox to allow the
user to control the service and to also indicate the service status.
public class VoiceMailNotifier extends BroadcastReceiver
{
public void onReceive(Context arg0, Intent arg1)
{
SharedPreferences ConfigData =
arg0.getSharedPreferences("user_prefs",
arg0.MODE_PRIVATE);
Boolean StartAtBoot = ConfigData.getBoolean("key_service", true);
if (StartAtBoot) {
Intent startServiceIntent = new Intent(arg0,
VoiceMailNotifierService.class);
arg0.startService(startServiceIntent);
}
}
}
OnPreferenceChangeListener ServiceActiveChange=new
OnPreferenceChangeListener() {
@Override
public boolean onPreferenceChange(Preference preference, Object
newValue) {
boolean StartService = (Boolean) newValue;
if (StartService) {
Intent startServiceIntent = new
Intent(VoiceMailNotifierController.this, VoiceMailNotifierService.class);
VoiceMailNotifierController.this.startService(startServiceIntent);
} else {
stopService(new
Intent(VoiceMailNotifierController.this,VoiceMailNotifierService.class));
}
return true;
}
};
