  1. Launch “AVD Manager”
  2. Click the "Edit this AVD" of the virtual device you want to use in Android Virtual Device Manager. enter image description here

  4. Go to "Emulated Performance" section in (AVD's) Virtual Device Configuration and select "Cold boot" of "Boot option:" and click "Finish". enter image description here
  5. Relaunch your virtual device and rerun your app on the emulator(Virtual Device).

Audio input in the Android emulator is not super reliable right now. Until it's fixed you can disable it with these steps:

  1. Launch “AVD Manager”

enter image description here

  1. On the crashing image, click the downward facing icon in the actions column and select “Show on Disk”

enter image description here

  1. In the folder that was opened should be a config.ini file, open it in your favorite text editor

enter image description here

  1. Change (or add) hw.audioInput=yes to hw.audioInput=no

enter image description here

  1. Save and close config.ini and relaunch that Android emulator image—it should now work without audio input errors

Sidenote: I had issues that are possibly related and also chose to add hw.audioOutput=no directly after hw.audioInput=no. You may want to try that if hw.audioInput=no doesn't solve it for you.
