I've been trying out some Android tutorials, and I have a problem with my emulator (I didn't used to have this problem):
When I hit the Home Button, it looks like this:
Even after waiting for half an hour, nothing shows up. Does anyone know why is it that the Home screen is blank ?

I am running an app built in Flutter on Pax A920 device with Android 7.1.2 installed.
Whenever the keyboard appears, the screen jumps down, and shows parts of the current view above the screen. When I dismiss the keyboard, everything goes back to normal.
This behaviour can be seen in the photo below. Sorry for the image quality, I cannot take screenshots on this device.
Photo of the unexpected behaviour
I cannot really show any code examples since this happens every time the keyboard appears, from different screens with different navigation stacks.
This works fine on iOS devices and on the Android emulators I have tried, so clearly this has something to do with the device/OS I'm running this on.
Has anyone experienced this or something similar and has an idea of how to prevent this?
I made a splash screen for my android app - therefore I followed the 3 steps described here https://stackoverflow.com/a/15832037/7589266
As I didn't like the result, I directly reversed the 3 steps. But the splash screen still showed up. Furthermore, I deleted the app from my smartphone, cleaned the project and rebuilt it. If I run the code now on the emulator, there doesn't show up a splash screen, but it still does on my physical device.
Does anyone have an idea how to fix this?
So, I'm a beginner developing an android app with eclipse.
When I launch it with Eclipse (to the real device) it goes as expected, but when I launch it after, from the device menu like any other app, it goes different.
The app is supposed to red out some imagebuttons, and grey out after pressing six of them. The thing is, when I launch it from the phone it immediately greys them out, not beginning with the red. I have no clue what it might be, should I post the code part? Does it make a difference?
I made my first hello world app, launched it on my smart watch (Gear Live), and it looks fine.
But then, as soon as my finger touches the screen, my watch turns into a pure black screen, and my hello world app is gone. There is nothing in Logcat, not a single word.
Is there a debug setting on this or something that I overlooked?
EDIT: Did more tests, out of 20 times I launched this app from Android Studio, all 20 of them showed "Hello World" on my watch, and 17 of them crashed when I tap anything. 3 of them did not crash when I tap, and they do not crash no matter what I do (until I swipe from left, which closes it).
Ok i can replicate this all the time now with these steps:
Open the app then press back which takes me out the app.
Open the app up again and just after the splash page i get black screen and freezes.
On back press i call finish(); is this correct way to terminate the app? I can only assume something's not getting closed properly first time round and causing app not to load properly when i reopen it.
Anyone heard of this before?
