Answer 1

I had the same problem and was bugged by it for two days. but this is what worked for me. one you get this error. try running your project (APP) again. it did the trick for me.

I had done everything. digged the web, installed and re-installed everything 4-5 times including the JDK as well. m not sure if it will help in the long run, but it seems to have worked for me.

Answer 2

unlock the screen from the emulator. That did the trick for me.

Answer 3

You might want to try out using Android Studio's AVD. That AVD seems to work better for me.

Answer 4

As for me, I had the same problem and it helped to increase SD volume and max VM app heap size. (Android SDK and AVD manager - Virtual device - Edit) What is interesting, the back change of SD and heap to the previous values is OK, too. That means, that any change of emulator parameters and its rebuilding is enough. (Simple restart won't help)

Definitely, it is cheaper, than total reinstalling. :-)

Answer 5

this kept happening to me ... how i solved it was to use " adb install " in a command prompt ...search for adb.exe if its not in your path. Make sure the emulator is running by going to run configuration and hitting run. This starts the emulator without installing your apk file. After the emulator starts up run the command prompt stuff listed above.
