Android Studio: Error:Execution failed for task ':app:dexDebug'
问题 I'm using Android Studio for the first time and I got the following error after importing the project (previously it was an eclipse project where I had issues too.) Here is the information given: Error:Execution failed for task ':app:dexDebug'. > com.android.ide.common.internal.LoggedErrorException: Failed to run command: /home/crash-id/Development/SDK/adt-bundle-linux-x86_64-20140702/sdk/build-tools/21.1.2/dx --dex --no-optimize --output /home/crash-id/AndroidstudioProjects/LocalSin/app
