How to create Adroid service?

Hi,

I would like to create an Android service, something that runs in the background all the time. I have seen an article in this forum talking about an Activity with BOOT_COMPLETED, is this the only way to do it? Ideally I would like the service to be hidden, i.e. not show up in an Activity Monitor, but I think I'm asking for too much ?

Thanks

Hello orbyone,

of course you can start an Service instead of the Activity.
Don't know if you can run hidden Services and stuff... no bad thing I hope

thanks for the reply plusminus (and great site by the way:)

could you be more specific? is all I need an XML with a service instead of an activity declared? could you type a sample XML perhaps?

Thanks!

Hello orbyone,

sth like this:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

public void onReceiveIntent(Context context, Intent intent) {
 
        Intent mainIntent = new Intent(context, KeepAlive.class);
 
        mainIntent.setLaunchFlags(Intent.NEW_TASK_LAUNCH);
 
        context.startService(mainIntent, null);
 
}

yes, this looks fine. but will the service still run when the launching activity is terminated?

Yes, the service will still run when his activity is terminated.

I also like to start the hidden service only. The main problem for me is, that you see the empty activity for a moment on the display.

How can I start a background service on android without any launching activity or Intent Receiver (like android.intent.action.BOOT_COMPLETED)?
Or how make the activity invisible?

Hello andbasti,

a IntentReceiver is not visible, isn't that what you want :?:

Thanks for reply

Yes, I can use an IntentReceiver to start Services, but overall not really hidden in the background, because I have to start an visible Activity before.

IntentReceiver can be registered static in AndroidManifest.xml (through the <receiver> tag) or dynamic with Context.registerReceiver(). But in both solutions an Activity is needed and I don’t be able to start Activities full invisible (without a blank screen at startup).

I have it now!

Just use IntentReceiver and install the apk file with adb.exe.

Thanks
