Delete the  gradle directory  Run your app again    Notes   The  gradle directory is in your project s root folder   You may have to show hidden files first    I have to do this every time I update a dependency module using Android 3 0   More recent releases of Android Studio 3 seem to have resolved the problem

In case the top answers haven t worked for you  your issue may be that you have multiple dependencies that depend on the same library    Here are some debugging tips  In this sample code   com google code findbugs jsr305 3 0 0 is the offending library   Always clean and rebuild every time you modify to check your solution     Build with the --stacktrace flag on for more detail  It will complain about a class  Google that class to find the library  Here s how you can set up Android studio to always run gradle with the --stacktrace flag  Take a glance at the Gradle Console in Android Studio View  gt  Tool Windows  gt  Gradle Console after a build Check for repeated dependences by running   gradlew -q app dependencies  You can re-run this each time you modify the your build gradle  In build gradle   android                       configurations all               resolutionStrategy                      Force a particular version of the library                     across all dependencies that have that dependency                 force  com google code findbugs jsr305 3 0 0                             In build gradle   dependencies               implementation  com google auth google-auth-library-oauth2-http 0 6 0                Exclude the library for this particular import         exclude group   com google code findbugs           In build gradle   android               configurations all           resolutionStrategy                  Completely exclude the library  Works for transitive                dependencies              exclude group   com google code findbugs                     If some of your dependencies are in jar files  open up the jar files and see if there are any conflicting class names  If they are  you will probably have to re-build the jars with new class names or look into shading     Some more background reading    Android - Understanding and dominating gradle dependencies Gradle Documentation  Dependency Management for Java Projects Gradle Documentation  ResolutionStrategy StackOverflow  Error Conflict with dependency   39 com google code findbugs jsr305  39  StackOverflow  How do I exclude all instances of a transitive dependency when using Gradle  Google search StackOverflow for all related questions

This hasn t been shared here yet so hopefully it can help someone    Following this link solved the same issue for me   To begin  I ll note that I did not have to set multiDexEnabled to true   First I set dependencies in my pubspec yaml to  dependencies    flutter      sdk  flutter   cloud firestore   0 8 2    and ran flutter packages get in my IDE s terminal   Also I had to change the minimum target SDK version    Open android app build gradle  then find the line that says minSdkVersion 16   Change that line to minSdkVersion 21  Save the file    This alone may fix your problem  however I had to also do the following because some of my dependency versions were mismatched    I had to open android app build gradle  then add the following line as the last line in the file  apply plugin   com google gms google-services   Next  I had to open android build gradle  then inside the buildscript tag  add a new dependency   buildscript      repositories                          dependencies                        classpath  com google gms google-services 3 2 1       new          After this my app finally ran on the android emulator    The link has a more complete walkthrough if you get stuck    Also  to note  I did not have to set multiDexEnabled to true

I agree with Chris-Jr  If you are using Firebase to embed your AdMob ads  or even if you are not  the play-services-analytics includes the play-services-ads even though you don t add that as a dependency   Google have obviously made a mistake in their 11 4 0 roll-out as the analytics is including version 10 0 1 of ads  not 11 4 0  the mouse over hint in the gradle shows this    I manually added compile  com google android gms play-services-ads 11 4 0  at the top which worked  but only after I disabled Instant Run   http   stackoverflow com a 35169716 530047  So its either regress to 10 0 1 or add the ads and disable Instant Run  That s what I found if it helps any

if 1  Try to clean and rebuild work   then good else if  2  Try to remove gradle work   then good else- gt  3  Try to add in grade properties android enableD8   false   Edit 2021  This 3rd option is deprecated now  use the other options  else- gt  4  Add multiDexEnabled true to your build gradle android       compileSdkVersion 26     defaultConfig                     minSdkVersion 15         targetSdkVersion 26         multiDexEnabled true                   and add the dependency dependencies       compile  com android support multidex 1 0 1    It may the first one works for u and so on but it really depends on the nature of your problem for me for example I got the error once I have added this library implementation  com jjoe64 graphview 4 2 2   and later I discovered that I have to check that and I have to add the same version of the support libraries  So I have to try another version compile  com jjoe64 graphview 4 2 1   and it fixes the problem  So pay attention for that

If you are using   compile   org apache oltu oauth2 org apache oltu oauth2 client 1 0 1     you should change it to  compile   org apache oltu oauth2 org apache oltu oauth2 client 1 0 1        exclude group  org apache oltu oauth2    module   org apache oltu oauth2 common      As the client lib already contains the common lib it creates a duplicate class entry which gives an error      Unable to merge dex

There might be a duplicated dependency  possibly nested in another dependency   Use  gradlew app dependencies  in the command-line to verify all of your dependencies   After removing duplicates  the problem was solved for me

UNABLE TO MERGE DEX SOLVED   After hours of stack overflowing  I resolved the   UNABLE TO MERGE DEX ERROR     Update all the com android support lines in your gradle to v27 1 0   Cause - Android has updated it support libraries to v27 1 0  so you have to change all the android support lines in your gradle file to 27 1 0 from 26 1 0   Make sure that the repositories section includes a maven section with the  https   maven google com  endpoint  For example   allprojects   repositories       jcenter       maven           url  https   maven google com              Cause  - Android cannot  update the support libraries in the SDK manager and now it uses maven google com to update   so you have to include this to use 27 1 0 support libraries  After Change Version   1  Clean Project  2  Rebuild Project

In my case  Unfortunately  neither Michel s nor Suragch s solutions worked for me   So I solved this issue by doing the following   In gradle 3 0 the compile configuration is now deprecated and should be replaced by implementation or api  For more information you can read here You can read the official docs at Gradle Build Tool     The compile  configuration still exists but should not be used as it will not offer  the guarantees that the api and implementation   configurations provide    it s better to use implementation or api rather compile   just replace compile with implementation  debugCompile with debugImplementation  testCompile with testImplementation and androidtestcompile with androidTestImplementation  For example  Instead of this   compile  com android support appcompat-v7 26 0 2  compile  com android support support-v4 26 1 0  compile  com github bumptech glide glide 4 0 0    use like this   implementation  com android support appcompat-v7 26 0 2  implementation  com android support support-v4 26 1 0  implementation  com github bumptech glide glide 4 0 0    After that    Delete the  gradle folder inside your project    Note that  in order to see  gradle  you need to switch to the  Project  view in the navigator on the top left   Delete all the build folders and the gradle cache   From the Build menu  press the Clean Project button  After task completed  press the Rebuild Project button from the Build menu    Hope it will helps

I tried every other solution  but no one worked for me  At the end  i solved it by using same dependency version by editing build gradle  I think this problem occurres when adding a library into gradle which uses different dependency version of support or google libraries    Add following code to your build gradle file  Then clean and rebuild project      ps  that was old solution for me so you should use updated version of   following libraries    configurations all   resolutionStrategy eachDependency   DependencyResolveDetails details - gt      def requested   details requested     if  requested group     com android support             if   requested name startsWith  multidex                  details useVersion  26 1 0                  else if  requested group     com google android gms             details useVersion  11 8 0            else if  requested group     com google firebase                 details useVersion  11 8 0

Pay attention to Warnings   Sometimes you only need to eliminate warnings and the error will be disappeared automatically  See below special case     I had these two dependencies in my module-level build gradle file   implementation  com android support appcompat-v7 27 0 2  implementation  com android support recyclerview-v7 27 0 2    and Studio had warned  in addition to dex merging problem       All com android support libraries must use the exact same version specification  mixing versions can lead to runtime crashes   Found versions 27 0 2  21 0 3  Examples include com android support animated-vector-drawable 27 0 2 and com android support support-v4 21 0 3   So I explicitly determined the version of com android support support-v4  see here for details  and both problems  the warning and the one related to dex merging  solved   implementation  com android support support-v4 27 0 2      Added this line  according to above warning message  implementation  com android support appcompat-v7 27 0 2  implementation  com android support recyclerview-v7 27 0 2      See below comments for other similar situations

Enable  defaultConfig      multiDexEnabled true   If step 1 doesn t work then  Go to project structure and find out the external library which is using a different version  Double click on it and delete its jar file  Close the project and open again android studio will rebuild the project  The problem should be gone
