Crash While Trying To Launch Any Application

Android studio doesn't launch any application (even new from the studio templates) and fails with the same error: 09/29 13:54:36: Launching app $ adb push /Users/user/AndroidStudio

Solution 1:

try adding this to your manifest on MainActivity

<activityandroid:name=".MainActivity"......
        <intent-filter><actionandroid:name="android.intent.action.MAIN" /><categoryandroid:name="android.intent.category.LAUNCHER" /></intent-filter></activity>

Solution 2:

This is happening....

Error: Activityclass     {com.example.user.myapplication/com.example.user.myapplication.MainActivity} does not exist.

Your MainActivity class does not exist or something which has been fixed as your launcher activity. Check your manifest file. In your manifest file you have delcared MainActivity as your launcher Cheers

Solution 3:

If you are using android studio version 2.1 and you enable instant run feature then some times these type error occur.

Clean your project or rebuild then problem resolved. for avoiding this problem disable instant run feature from setting
