Android Tablet adb shell command Questions

[whitehorsey]

I've been testing out the adb shell am display-size and adb shell am display-density on my 10 inch tablet using the command prompt. The adb shell am display-density is considered an unrecognized command while adb shell am display-size, I was able to change the display size to 800x500 but not to 1280x800 (7 inch display size?). I want to test an Android app I created on a 7 inch display size. Also, the three buttons on the bottom where the home/back key is disappears. They won't reappear even when I do adb shell am display-size reset. The only way to get the keys back are by restarting the whole system. How can I fix these problems?

There are a few ways to fix these problems. First, you can try using a different command to adjust the display size. For example, you can use the 'wm size' command instead of the 'am display-size' command. This command should also allow you to adjust the display size to 1280x800. Second, you can try using an emulator such as Genymotion or BlueStacks. These emulators allow you to simulate a device with a 7-inch display size and will not require you to use any commands to adjust the display size. Finally, you can try using a virtual machine such as VirtualBox. This will allow you to run an operating system on your computer which has a 7-inch display size. You will be able to test your app in this environment without having to restart the whole system.

The best way to fix these problems is to use an emulator. An emulator allows you to simulate different display sizes and densities on your computer so that you can test out your app on different screen sizes and densities. This way, you don't need to reset your device every time you want to test out a different display size or density. You can find many free emulators online such as Genymotion, Android Studio's emulator, and Bluestack.
