Answer 1

I had this problem on my MacBook Pro and found that I had to turn off my Bluetooth before launching the emulator.

Answer 2

Be sure you read MediaPlayer State Diagram and that you perform all requested actions when you close your MediaPlayer object; if you don't stop, reset and realeas it, next time you try to use it, it will be in an incoherent state so that you cannot start it.

Answer 3

Looks like the issue is only on my computer. I just tryed it on another computer and it work fine. I had some issues when I upgraded to r10 of ADT. Maybe there is something wrong in my development setup.

Answer 4

I see this problem on mac os as well. In my case it happens when you enable "snapshot" for the emulator.

You will have to delete the emulator and make a new one without "snapshot" enabled.

Answer 5

Launching the emulator manually helps in my case.

emulator program can be found inside android-sdk/tools/.

So the final command will be something like:

android-sdk/tools/emulator -avd my_cool_emulator_name
