Android Question Start PhoneCall from background service

[Nerdworld]

Hello folks,

I tried adding the FLAG_ACTIVITY_NEW_TASK and FLAG_FROM_BACKGROUND flags to the Phone call intent, as mentioned here:

Android: Make phone call from service

I try to make a phone call from inside a service. The code I use is: Intent intent = new Intent(Intent.ACTION_CALL); intent.setData(Uri.parse("tel:" + number)); startActivity(intent); and it work...

stackoverflow.com

Dim P As PhoneCalls
Dim In As Intent = P.Call(Param)
In.Flags = Bit.Or(268435456, 4) 'FLAG_ACTIVITY_NEW_TASK + FLAG_FROM_BACKGROUND
StartActivity(In)

Dim In As Intent
In.Initialize2("tel:" & Param, Bit.Or(268435456, 4))
In.Action = In.ACTION_CALL
In.Flags = Bit.Or(268435456, 4) 'FLAG_ACTIVITY_NEW_TASK + FLAG_FROM_BACKGROUND
StartActivity(In)

It's not working and i'm getting no error message or hint. Code works fine when called while the Main activity is running.
Any ideas?

I don't really see what this topic has to do with my question.
Receiving intents and broadcasts as well as receiving SMS in my background service already works fine.

I've found an possible answer here: https://stackoverflow.com/questions/47927694/how-to-make-calls-from-a-background-service

But i'm not sure how to translate the Handler().post(new Runnable() part into B4A.

You may not be able to do exactly that you want, but there seems to be a possible alternative.

Both of them have slightly different problems - i don't want to hide the dialer (and let the call run in background), i just want to start a call while my own application just runs as a background service - for example when the screen is off or while I'm doing something else.

The problem is, that you can't call StartActivity from an Service module - and CallSubDelayed just waits until you reopen the app.

Not 100% correct. See Android 10 section: android.jar / targetSdkVersion / minSdkVersion

Just adding:

AddPermission(android.permission.SYSTEM_ALERT_WINDOW)

to the Manifest does the trick!

The solution just works fine, as always - thanks a lot!

Not correct. It is not enough on Android 10+.

 

[Nerdworld]

Adding the permission allowed me to change this option in the App settings.

At least on my HUAWEI Mate 20 Pro with Android 10.1 this seems to be enough.

You previous post will confuse other members who read your thread.
It is exactly not "just adding the permission".

Anyway, all the information needed is available in the tutorial: https://www.b4x.com/android/forum/threads/87610/#content
