Question

When I run an android app from eclipse I meet this error and my app does not start:

Installation error: INSTALL_FAILED_MEDIA_UNAVAILABLE

Answer 1

If none of the fixes above worked for you, like it didn't for me, there's a really simple fix you could consider.

In your USB computer connection settings, uncheck the "Mount SD card" box and leave it only checked at "Media device (MTP)". Then run the app again.

This way your external storage won't be unmounted when you connect your device to your pc and your app will then install successfully
