android-service

I want to launch a Service when the app is launched instead of an Activity; and then said Service will launch an Activity . I need to do this because my app needs to be running ALWAYS, and when I say ALWAYS I mean ALWAYS. And the only way I've managed to avoid the OS killing my app is by starting a service as Sticky and should Android kill either my Activity or my Service I'll restart them right away. I found this question but the top answer seems rather clumsy, any one has a better idea? PS: I know this doesn't look like a very friendly app but this is a very specific research scenario and it

I understand that a service can run in two modes, started and bound. What I don't quite understand from the developer docs or other questions on this site, is whether a service running as both started and bound will exit when the last component unbinds from it? whether a service running as both started and bound will exit when the last component unbinds from it? If something called startService() on the Service , it will remain running, regardless of what bindService() and unbindService() calls may have gone on. Eventually, Android will stop the service, or the user will kill the service, but

My app has a widget that shows today's date and need to be updated on midnight. The widget is defined in the manifest as <manifest> ... <application> ... <receiver android:name=".MyWidgetProviderClass" android:label="MyLabel" > <intent-filter> <action android:name="android.appwidget.action.APPWIDGET_UPDATE" /> </intent-filter> <meta-data android:name="android.appwidget.provider" android:resource="@xml/widget_icon_info" /> </receiver> </application> </manifest> And the widget info file is <appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android" android:initialLayout="

I am creating the voice recognition service like "Ok Google" with custom command. For this I have used the VoiceInteractionService and I refered the code from here . Also, I am getting the STATE_HARDWARE_UNAVAILABLE error in onAvailabilityChanged . public class VoiceCommandService extends VoiceInteractionService { private static final String TAG = "AlwaysOnHotwordDetector"; Locale locale = new Locale("en-US"); protected SpeechRecognizer mSpeechRecognizer; protected Intent mSpeechRecognizerIntent; public final Callback mHotwordCallback = new Callback() { @Override public void

I developed an app and some people complains that it takes too much battery, it is the second most consuming process after the screen. However, in some devices it does not consumes that much battery. All the work my app do is in a service. The service is sticky and is running all the time (the android system may kill it when has low resources or pause it when device go to sleep), it has listener to the accelerometer as long as the screen is on, it is not foreground service and does not hold wakelock. Can someone tell me why it takes a lot of battery? And why is this happening only on some of

I'm trying to launch service and then open socket to have connection with server. On button click I create new Thread and then start service.
