Weird : UNEXPECTED TOP-LEVEL EXCEPTION: Execution failed for task app:dexDebug

Question

I didn\'t implement new libs but this problem occured while coding :

Error:Execution failed for task \':app:dexDebug\'.

com.android.ide.commo

Answer 1

I solved my problem with adding these in build gradle:

    defaultConfig {
      multiDexEnabled true


    dependencies {
      compile 'com.android.support:multidex:1.0.0'

another solution can be removing unnecessary libraries
