Android Question Widget with API 26

Cebuvi · Mar 1, 2018

Hello

I have verified that with API 26 the widgets of my application do not update and stop responding.

Will this be solved with the new version of B4A?

Thanks.

Yes.

Please check the unfiltered logs and post the error message.

Thanks for the quick reply.

I checked it when my phone was updated to Android Oreo. Now I will test with an ADL and send you the logs.

...i have the same problem on nexus 5x oreo 8,1.
widgets work fine with target sdk 25 while crash with ANR when target sdk is set to 26

Hi,

This is the text of the log after several clicks to update and open the app.

Erel · Mar 4, 2018

I will check it.

Star-Dust · Mar 8, 2018

I have the same problem too.
Already in the past the starter service created problems with Android 7 and later the DropBox library.

Now they start only once as soon as I install the App and then it does not start anymore.
If the App is started in the background, it does not even enter the widget

Star-Dust · Mar 8, 2018

This is a simple example.

The widget starts only if the App is started or in backgroumd.
If you kill the App and call the widget nothing happens anymore

Erel · Mar 9, 2018

It will work in B4A v8. It is related to the new background restrictions in Android 8.

Star-Dust · Mar 9, 2018

Is it possible now with B4A7.30 to request some permission to unlock the widget?
Many Google users who use our Apps send us continuous reports.

DonManfred · Mar 9, 2018

I guess no; you need to wait for V8 to be released and use this Version then.

It should work if targetSdkVersion is less than 26.

Star-Dust · Mar 9, 2018

Yes, it works. But I have already published with the Target version 26. Google sent me a message at the time of publication that I can not relegate the target version.

Only I had not tried the widget with Android 8, but with previous versions. Only yesterday I did a test on an updated device

Erel · Mar 9, 2018

I'm not sure that you cannot lower it to 25 or 24. There is a hard limit with 23.

You should never release an app with targetSdkVersion higher than the version you tested it on.

Star-Dust · Mar 9, 2018

I realize that I was wrong not to try it in all its functions

DavideV · Mar 12, 2018

Hi Erel,
both my widgets seems working correctly after compiling them with B4A V8 and following this tutorial
Thanks!

After compiling with B4A 8.0 it now works without making any changes to the original code.

I suppose it does not require any change from the old tutorials
