Android Question [SOLVED]On API26 Notification recreate activity instead of resume

[KZero]

Hello,

i tried both built in notification and notification builder
both on API 26 recreating the activity when i click on the notification even if the activity is active

any idea how to just resume the activity as usual ?

Take a look NB6 sample https://www.b4x.com/android/forum/threads/nb6-notifications-builder-class-2018.91819/, for example, under API 26 emulator.
Even if your app is in background and you click in notification bar, your app will be activated and log shows Activity_Resume event only.

Thanks Semen,
it works but only in B4a 8+ there is no anyway for B4a 7.8 ?
as b4a 8 require some changes to my projects and no time to do that now

The Notification object is rewritten in B4A 8 due to Api changes.
Don´t know how to do it in older Versions.

Note to go over this tutorial
https://www.b4x.com/android/forum/threads/firebase-notifications-firebase-auth-issues.94200/
- The notification object is rewritten.
- The Manifest entries has changed. <--- Note that you need to redo the Changes to include Firebase. Some of them are changed....

Yes, but not a lot. Two-three hours, mainly manifest. + Services are "Oreo-ready".
Most of us made changes - nothing terrible.
Just now it's necessary to think about API26+ - all new smartphones during last year have Android 8.0/8.1.

And to use Api 26 successfully you need B4A 8+ -> Time to update B4A

You should expect your activity to be destroyed and recreated on all kinds of cases. This is how Android works.

I know about Activity life cycle , in my case the activity not destroyed to be created again
updated to B4A 8.5 it is ok if the notification calling the last active activity , if not the activity recreated


changed manifest for the activity android:launchMode to singleTask instead of singleTop fixed the problem

Thanks

The B4A version is not related to this behavior.

I don't recommend it. Make sure to test your app carefully.
