Android Question Application does not appear in the Task List

[adriano.freitas]

Hi!

I've been having a problem that I'm not able to solve, although I think it's simple:

The application doesn't appear along with others running when I press the android task button. If I'm using the app and I need to switch to any other (like whatsapp etc), then it's not possible to return anymore, it's necessary to restart the app, reset the password, etc... Any suggestions?

Which app? Your B4A app? You don't need to do anything special for it to appear in the recent apps list.

Hi! Yes, in my app. I'll illustrate with pictures. Look at image 1. The application is running. In figure two, when you press the activities button, it is there. Then I need to switch to whatsapp, as shown in figure 3. Then I need to go back to the app and it no longer appears. If I try to open it again, it starts the whole process (login, etc) and not where it left off.

Have you done anything special in the manifest editor?

I used the manifest as it is initially generated and added some things that I collected here to use the Google calendar, etc. I'll put the manifest here so you can see:

Remove this line: SetActivityAttribute(Main, "android:excludeFromRecents", "true")

Hi! Perfect! That was it! I was really dumb, as this code already says it is the cause of the problem, but as I'm new to these platforms (Android and V4A), I didn't pay attention to it! Thank you very much!
