Android Error – The Emulator Disconnects and Doesn’t Launch the App

Does Eclipse show "Emulator-XXXX disconnected" even though the Android emulator works fine? Find out why it happens and how to fix it quickly.

When you try to run the emulator from  Eclipse, you may get the following error on screen even though the emulator works perfectly:

Emulator-XXXX disconnected! Cancelling ‘actividadEjecutora activity launch’!

This error can happen for several reasons. One of the best known is that the computer running the emulator is not very powerful, so the emulator takes so long to load that Eclipse loses the connection to it; it can also happen after several successful launches on the emulator.

Solution

There’s nothing else to do but close the disconnected emulator and restart it. When you launch the app again, the emulator usually starts up once more.
