With some effort I finally managed to install Qt for Android and wrote my first testing app. Everything went ok when debugging(usb debugging on galaxy s5) but after deploying the app via "Bundle Qt libraries in APK" and installing+running it on the phone I encountered a problem.
The design of the app changes after the first time run. The left screenshot is how the app looks after installing and tapping 'Open'; the right one is made after closing the app via the back button and opening it again from the app drawer:
(The add button in the first image is blue because it was in focus)
As you can see, the slider(QSlider) theme changes, and the 'Add' button also gets smaller.
I've also built and deployed the app with the x86 kit(instead of armeabi-v7a) and installed it on Genymotion Nexus 5 emulator, getting the same strange behaviour.

I'm talking about the IDE action highlighted in image below:
Whenever I use the shortcut, sometimes it just installs and that's it. Then if I press it again, it then runs the app. The earlier behavior used to be Install + run app every time.
So, it's quite frustrating because five years of muscle memory has me relying on the shortcut functioning as expected and I can't get used to how it works right now because it is totally random.
Anybody else experiencing this? Have you found any fix?
I'm on the latest Android 4.0 (Canary 9).
I developed an Android app using Android Studio and it perfectly works on different devices. The apk was generated as signed.
I've tried to install it (through the apk file, using the package installer) on an LG K20 (Android 9) but I noticed an issue: the installation process ended successfully, but the app icon on the device screen wasn't created. So, I'm not able to execute it.
Moreover, if I connect the device on my laptop and I launch the app from Android Studio, the icon is not created.
On the other hand, if i install an app through the Play store, the icon app is created.
Is there any security option I have to disable in order to complete the icon creation?
I solved.
Actually, the app was installed and the icon was correctly created.
The positioning of icons on the device screen is a little bit confused: if you install apps from the Play store, icons will be placed in a view accessible scrolling horizontally; but if you install app from apk files, icons will be placed in a view accessible scrolling vertically.
I usually scroll the device view horizontally, so I couldn't see the icon app.
currently i'm developing an App with the Framework Ionic2 / Cordova.
The application is ready for the beta test and i uploaded it to the Google Play Store. In the release everything works realy good.
Today i tried to change some stuff in the code and recognized a problem, when i run the application from my pc on my phone.
After the splash screen there is a white screen showing up for about 30s !
Ich checked the device with the debugger and after the app is installed the "Device is ready" fires after 3s. For the whole rest of the 30s nothing is happening. After that the app shows up and everything is working like before.
I have already tried to build the app with --prod --release but it makes no difference.
So my first choice was to reset my project to an older git commit to fix the problem, but now in every! commit the screen is white for about 30s. I can go back like 10 commits and it still there.
I was thinking about an problem with the cordova plugins or something like that and that's why the problem occurs in every version now.
Could that be possible or someone of you has advice for me?
/edit:
Intriguingly when i want to debug the app and run it with
ionic run android --livereload --consolelogs
it shows no error, the white screen after splash is still there, but it only lasts like 5 seconds
I added myself as a tester for my Android app. Received and opened the email on my Android device. Got to this screen:
Clicked on "Download" and got this:
The problem now: The "INSTALL" button doesn't work, i.e., it's not clickable.
This was on Nexus 5X Android 7.0.
Make sure there aren't any apps drawing to the screen like screen dimming apps (see: https://android.stackexchange.com/questions/69981/why-cant-i-press-the-install-button-when-installing-applications-from-unknown-s).
I have only just started android programming, but I have a few basics programs working. Normally when I click run in Android Studio and choose my galaxy nexus as a running device, the app I'm running opens and is saved onto my device, so that I can open my program when I am not plugged into my computer.
However, now when I hit run, my program opens, but it is not saved onto my device.
This happened almost immediately after I changed my application label in my manifest file, but I'm not sure if that's related. Any help is appreciated!
Make sure that "deploy the APK" is selected in Run-> Edit Configurations
You have to set it at the new project screen. Its greyed out but theres a link next to it. Just click it. Its next to the Package name and that is the only .app extension you need to execute the apk.
I had the same issue. For me the problem was that the icon was not appearing on the screen but I found the app was actually stored on the device. I have installed NovaLauncher on a Meizu U20. I went to see the "Applications List" (tr. it. "Menu delle app"), I found my app icon there and I drag/dropped it on the screen.
