As other have said  this error occurs because the emulator is still in the process of launching  An attempt to access the package manager  for the device  at this time causes an error   It s just a simple timing issue  Here are the steps to avoid this error    Wait until the emulator  lock screen  is showing  Run the  app  again   R in most IDE s   Choose the running device  Should be the same emulator     App should install without error

Once you see this error  wait for emulator to show lock screen  And then relaunch the app in your IDE and check the emulator again  It works for me always    In Android studio  you can relaunch by clicking the green play button or ctrl   r

You need to wait for the emulator to full start - takes a few minutes  Once it is fully started  UI on the emulator will change   it should work   You will need to restart the app after the emulator is running and choose the running emulator when prompted

In my case it was just that the emulator took 9 minutes to start  Wait until you see the lock icon on the emulator LCD   Or use actual tablet or phone
