Android studio: emulator is running but not showing up in Run App "choose a running device"

I have launched my emulator via the AVD manager and once it's running I have clicked on run app. I have waited a couple of minutes for my running device to show up in choose a running device but the window always stays blank.

Solution

Probably the project you are running is not compatible (API version/Hardware requirements) with the emulator settings. Check in your build.gradle file if the targetSDK and minimumSdk version is lower or equal to the sdk version of your Emulator.

You should also uncheck Tools > Android > Enable ADB Integration

If your case is different then restart your Android Studio and run the emulator again.
