I can’t figure out why this keeps happening. Every emulator that I have created will at some point or another develop a weird glitch on the home screen that makes the device look as if the screen is cracked internally. This doesn’t seem to change the way that my apps run or operate. However it is rather frustrating especially seeing as there seems to be no consistency as to when the screen will bug out. Also I can’t for the life of me figure out what could possibly be causing the change to occur. Seems to happen at randomly sometimes it will be from the first launch of the emulator and other times I’ll use the emulator for a few days and then it will just boot up with the same visual bug out of no where.

Below is the event log from the launch I used to take the screenshot.

Below this is an event log from a 2nd launch after completely closing the emulator.

  2. I ran into the same problem when I updated Android Studio

    Here’s how I solved it:

    1. open adb.exe dir. like ..AndroidSdkplatform-tools
    2. delete all
    3. open Android studio -> File | Settings | Appearance & Behavior | System Settings | Android SDK -> sdk tools -> Android SDK platform-tools
    4. reInstall Android SDK platform-tools

    I use this method to get ADB working again.
