I am not able to run/execute my project in Android Studio. How can I resolve this issue?

Answer 1

Resolved :

Disable the Instant Run option in Android Studio 2.0 Preview

Answer 2

Something you can try is deleting the build folder. That does not always work but fixes it sometimes.

rm -rf cart/build

If that does not work. Run that command then in Android Studio select invalidate caches and restart.

Answer 3

This problem happen when the used gradle have problem with instant run.
So to solve this you have to either change gradle version or disable instant run.

        minifyEnabled true
        proguardFiles 'proguard-android.txt', 'proguard-rules.pro'
    }
    debug {
