Hi,

You have to give more details about your system and device.

NickV

I use a Huawei P9 lite.
My system is android 8.
I've tried the code that i mention before but focus still not work. It worked once but now i have again the same problem.

That's not your code, but just something you call in your code. You should show your code

@NickV Do you have to use such an old Qt version?

I use Qt 5.9.6.
As far as i know since qt 5.5 there is no such problem. Correct?

I don't know. There could be bugs in older versions which were fixed in newer. That's why I suggest to test with current Qt version. Especially Android is changing quite fast, old Qt versions could have issues with newer Android versions.

In order to do that i have to build postgres driver for android for qt 5.13. But as i have mention to other post i have problem with that.

@NickV You could create a small test app where you only try to use the camera...

@jsulm
This is a little bit difficult right now. About the other post at least any suggestion in order to build postgres?

jsulm

@NickV No, I never build it. And I'm wondering why you would need it on an Android device? Are you going to connect directly to postgres server from Android device? Over Internet or Intranet?

Yes. My application is very old, but i need new Qt now. I can not change the whole application in order to use api calls right now. I know that this architecture is very painful and problematic but this is that i have for now.
