I know that the problem was answered  but this could happen again and my solution was a little different from the ones that I found  In my case the solution wasn t related to include two different libraries in my project  See code below   compileOptions       sourceCompatibility JavaVersion VERSION 1 8     targetCompatibility JavaVersion VERSION 1 8     This code was giving that error  Unexpected Top-Level Exception   I fix the code making the following changes   compileOptions       sourceCompatibility JavaVersion VERSION 1 7     targetCompatibility JavaVersion VERSION 1 7

This might be the dumbest answer  but this worked for me     I removed and added all the libraries on my project manually  One after the other  And voila  it worked  Build -  Rebuild project    Note  No library of mine was compiled twice

The error occurs when you have the same library directory included more than once in your build gradle s dependencies  Ok  let   s say you have an App structure that looks like this     So you have the main    app    and then you have a bunch of sub-apps modules libraries  The libraries are  1  gene test library  2  genes nine old androids library   amp  3  swipe list view library    My name is Gene  so that   s why there are all these    gene    libraries   Inside the build gradle for    app     I have   dependencies       compile fileTree include      jar    dir   libs       compile  com android support appcompat-v7 21 0 0       compile project   libraries gene test library         compile project   libraries genes nine old androids library       compile project   libraries swipe list view library       Inside the build gradle for gene test library  I have nothing   dependencies       Inside build gradle for gene nine old androids library  I have   dependencies       compile fileTree dir   libs   include      jar        compile  com android support appcompat-v7 21 0 0      Inside build gradle for swipe list view library  I have   dependencies       compile  com nineoldandroids library 2 4 0       compile fileTree dir   libs   include      jar        compile  com android support appcompat-v7 21 0 0      This line of code    compile fileTree dir   libs   include      jar       just means    hey  look inside the    libs    folder inside this module for any jar files  I do not have anything in the libs folder of any of the modules so you can ignore that line of code    So let   s say I uncomment out       compile project   libraries genes nine old androids library   In the build gradle for the    app    module  Then I would get the    UNEXPECTED TOP-LEVEL EXCEPTION     error  Why is that      Well  writing   compile project   libraries genes nine old androids library   inside the build gradle for    app     is the same as taking the build dependencies of    genes nine old androids library    module and putting it there  So uncommenting the   compile project   libraries genes nine old androids library   statement   the build gradle for    app    module becomes    dependencies       compile fileTree include      jar    dir   libs       compile  com android support appcompat-v7 21 0 0       compile project   libraries gene test library          compile fileTree dir   libs   include      jar              compile  com android support appcompat-v7 21 0 0         compile project   libraries swipe list view library       Notice how now    compile  com android support appcompat-v7 21 0 0     shows up 2x  That   s where the error is coming from

Like everyone else said here  the support library  com android support  is being included more than once in your project  Try adding this in your build gradle at the root level and it should exclude the support library from being exported via other project dependencies   configurations       all  exclude group   com android support   module   support-v4      If you have more then one support libs included in the dependencies like this  you may want to remove one of them

In my case TOP LEVEL EXCEPTION was throw because of a special char in project path  Just closed the project  changed      to  a  and reopened the project  Works

This happens when a library is getting compiled twice  i e it is added two time   It can be support library or any other  it doesn t matter  The common case is that you have added a compile statement of a library which is already in your libs  directory  All the   jar files are compiled automatically  Thus  adding a compile statement is causing the error  Removing that statement might fix this issue  If this is not applicable then we already have some awesome answers

Make sure you have downloaded Support Repository to use support library dependency in build gradle     If these all are there already installed sync your project with gradle once using the button available

Suddenly  without any major change in my project  I too got this error   All the above did not work for me  since I needed both the support libs V4 and V7   At the end  because 2 hours ago the project compiled with no problems  I simply told Android Studio to REBUILD the project  and the error was gone

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

I found 2 reason for this issue    Sometimes its because of multiple included libraries  For example you add   compile  com nineoldandroids library 2 4 0    in your gradle and add another library that it also use  nineoldandroids  in it s gradle     As Android Developer Official website said       If you have built an Android app and received this error  then congratulations  you have a lot of code    So  why      The Dalvik Executable specification limits the total number of methods that can be referenced within a single DEX file to 65 536  including Android framework methods  library methods  and methods in your own code  Getting past this limit requires that you configure your app build process to generate more than one DEX file  known as a multidex configuration    Then what should you do    Avoiding the 65K Limit - How    Review your app s direct and transitive dependencies - Ensure any large library dependency you include in your app is used in a manner that outweighs the amount of code being added to the application  A common anti-pattern is to include a very large library because a few utility methods were useful  Reducing your app code dependencies can often help you avoid the dex reference limit  Remove unused code with ProGuard - Configure the ProGuard settings for your app to run ProGuard and ensure you have shrinking enabled for release builds  Enabling shrinking ensures you are not shipping unused code with your APKs   Configuring Your App for Multidex with Gradle - How  1 Change your Gradle build configuration to enable multidex    put  multiDexEnabled true   in the defaultConfig  buildType  or productFlavor sections of your Gradle build file   2 In your manifest add the MultiDexApplication class from the multidex support library to the application element    lt  xml version  1 0  encoding  utf-8   gt   lt manifest xmlns android  http   schemas android com apk res android      package  com example android multidex myapplication  gt   lt application             android name  android support multidex MultiDexApplication  gt           lt  application gt   lt  manifest gt    Note  If your app uses extends the Application class  you can override the attachBaseContext   method and call MultiDex install this  to enable multidex  For more information  see the MultiDexApplication reference documentation     Also this code may help you   dexOptions       javaMaxHeapSize  4g      Put in your gradle android

I had similar problem when I tried to build a signed apk for my app    Strange  it happened only when I wanted to build a release apk  while on debug apk everything worked OK    Finally  looking on this thread  I checked for support library duplications in build gradle and removed any duplications but this wasn t enough     I had to do clean project and only then finally I ve got it to work

Because you may include two same libs in your project  check your build gradle file   dependencies       compile  com android support appcompat-v7        compile files  libs android-support-v4 jar         if your file includes compile  com android support appcompat-v7    and compile files  libs android-support-v4 jar    it will have this problems  delete this sentence   compile files  libs android-support-v4 jar    That s how I fix this problem

dependencies       compile  com android support support-v4 19 1        compile fileTree dir   libs   include      jar        This gets conflicted if you have the support jar in your libs folder  If you have the support jar in your project libs folder and you have the module dependency added to compile  com android support support-v4 13 0    the UNEXPECTED TOPLEVEL DEPENDANCY exception will be thrown

Hi all I had the same issue that was being caused by a duplicate support version 4 file that I had included while trying to get parse integrated  Deleted the extra inclusion from the libs directory and it works fine now
