I had the same problem too  In my case the problem started after a reboot   I closed my App  then I closed the Android Studio  In my case V1 1 0   and finally a normal shutdown  After that  I modified one java file to add a RadioGroup object and then the problem appeared   I solved my problem only changing a simple  0  for a  1  in my Gradle configuration file  because the root cause of the problem was generated at the Gradle execution process  Previously I used to have version  1 0 0  then i changed it to  1 1 0   as stated in the pictures   Location of the Gradle configuration a changed   Location where I took the right version from  File -  Settings -  Gradle -  Experimental

I had this problem because I tried to use both support library and appcompat    dependencies       compile fileTree dir   libs   include     jar       compile  com android support support-v4 23 1 0      compile  com android support appcompat-v7 23 1 1      compile  com android support design 23 1 1      compile  com google android gms play-services 8 3 0      After I deleted support library and changed to older version  it compiled    dependencies       compile fileTree dir   libs   include     jar         compile  com android support appcompat-v7 23 1 1      compile  com android support design 23 1 1        compile  com android support appcompat-v7 22 2 0      compile  com android support design 22 2 0      compile  com google android gms play-services 8 3 0

Could fix this by adding   compile  com android support support-v4 18 0 0    to the dependencies in the vertretungsplan build gradle  compile and then remove this line and compile again    now it works

A reason can be duplicated libraries after importing from Eclipse IDE   dependencies   compile  com github japgolly android svg-android 2 0 5  compile  com google android gms play-services    compile  com android support appcompat-v7 21 0 3  compile files  libs androidannotations-api-2 7 1 jar   compile files  libs androidasync-2 1 2 jar     compile files  libs google-play-services jar   compile files  libs universal-image-loader-1 8 2 jar      I had the same problem  after comment     compile files  libs google-play-services jar     The app get no errors

Many of the answers here are trial and error to find duplicate dependencies but if you scroll up just a little bit from the Execution failed for task   app dexDebug   line it will give you a hint at the duplications      In my case I had the following error   UNEXPECTED TOP-LEVEL EXCEPTION  com android dex DexException  Multiple dex files define L com parse AbstractQueryController 1              Execution failed for task   app dexDebug     So I knew that in order to fix this bug I needed to find the duplicate dependencies that define parse AbstractQueryController  In my case I had two imported modules that were loading in two different Parse libraries   Making my project only load one fixed my issue

The problem is NOT about Execution failed for task   dexDebug   if you look above the error showed in red you are going to see this     To solve this problem permanently just add these lines in your build gradle file  android       dexOptions           jumboMode   true           For further details check this question  here

I got the same sort of error when I tried to compile a utils library jar in eclipse using Java JRE 1 8  and use it in my  libs  in Android Studio 1 1 0   I had my Android Studio set to use JDK1 8 0   I switched my Eclipse to work with JRE 1 7  and the error was fixed  Eclipse  Window- Preferences- Java tab- Compiler -  Compliance level 1 7  It will most likely prompt you to switch your JRE System Library to jdk1 7 x x   You may need to make sure to uncheck  compress jar  when you export  I haven t tested whether it had an effect or not  I doubt it was related

I have also ran into this error when the package in one of my class files was incorrectly spelled  Many of these answers immediately jump to the Jar files but I would also check to make sure your packages are spelled correctly

I faced the same issue  Resolved by doing this   Go  to actionbarsherlock -  module settings - dependencies  Remove the support v4 library  In bottom left there is a plus button   from there add 1 Library Dependency  Select support-v4    Let the gradle resync and clean project once done

In my case  I did Build  gt  Clean Project and it worked

ANDROID STUDIO Users try this -  You need to add the following to your gradle file dependencies   compile  com android support multidex 1 0 0    And then add below line   multidex support application   to your manifest s application tag   android name  android support multidex MultiDexApplication

User · Answer

Make sure your AndroidManifest file contains a package name in the manifest node  Setting a package name fixed this problem for me

If you are also using Dagger or Butterknife you should to add guava as a dependency to your build gradle main file like classpath    com google guava guava 20 0  In other hand  if you are having problems with larger heap for the Gradle daemon you can increase adding to your radle file    dexOptions           javaMaxHeapSize  4g

I suddenly had the same problem  after no noteworthy changes   I solved it by deleting the app build directory and let gradle build the whole project new

The right answer is  that some of your jar files does not compile   You should go into your build gradle file in your project  and look in your dependencies    If you re just importing some jar files  you could try to remove them and add them one at a time  This will help you determine which one of them causes the error    In my case  I did just that  and when I was importing the last one  the app compiled  So I think the real problem was that I was importing too many at once  But now it all works

This might be the wrong thread  as your problem seems more specific  but it s the thread that I found when searching for the issue s keywords   Despite all good hints  the only thing that helped me  and that I d like to share just in case  if everything else does not work    Remove your  gradle directory in your home directory and have it re-build re-downloaded for you by Android Studio    Fixed all kinds of weird errors for me that neither were fixable by re-installing Android Studio itself nor the SDK

You must check if the same JAR is being imported again  In my case there was a class inside a jar which was getting imported in another jar  So just check if the any lib   class file is being included twice in the whole project

I found a very interesting issue with Android Studio and the mircrosoft upgrade to the web browser   I upgraded  stupidly  to the latest version of ie   of course Microsoft in their infinite wisdom knows exactly what to do with security   When I tried to compile my app I kept getting the error Gradle - build fails -- Execution failed for task   looking in the stack I saw that it did not recognize the path to java exe   I found that odd as I was just able to compile the day before   I added JAVA HOME to the env vars for the system  closed Android Studio and reopened it   Low and behold if the fire wall nag screen did not pop asking if I wanted to all jave exe through     What a cluster

I had two incompatible dependencies     The below dependencies caused the error     compile  com google android gms play-services-fitness 8 3 0  compile  com google android gms play-services-wearable 8 4 0    By changing the fitness dependency to version 8 4 0 I was able to run the app     compile  com google android gms play-services-fitness 8 4 0  compile  com google android gms play-services-wearable 8 4 0
