duplicated class caused by mulitedex dependecy in Android Studio

thank you for your support.
My issue is : When I added the multidex dependecy and try to export the signed apk, I get this error :
Error:Execution failed for task
':androidKeyboardThemes:transformClassesWithJarMergingForRelease'.
com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/google/android/gms/location/ActivityRecognition$1.class
My gradle dependecies are theses:
dependencies {
compile project(':cropper')
compile 'com.google.android.gms:play-services:+'
compile files('libs/StartAppInApp-2.4.7.jar')
compile files('libs/google-play-services.jar')
compile 'com.android.support:multidex:1.0.1'
}
I tried to delete one lib or jar at any time and build again but I couldn't get the job done.
Also I read all the unswer about duplicated class in stackoverflow but I failed again to solve my issue.
Any ideas?, thank you for your help.

dependencies {
compile project(':cropper')
compile 'com.google.android.gms:play-services:+' <-- choose either one
compile files('libs/StartAppInApp-2.4.7.jar')
compile files('libs/google-play-services.jar') <-- choose either one
compile 'com.android.support:multidex:1.0.1'
}
Whatever it is, please dont use play-services. inside compile 'com.google.android.gms:play-services:+' contains alot of dependencies.. see below.. using play-services may cause dex problem and heavy app. refer here

com.android.build.api.transform.TransformException: java.util.zip.ZipException

I imported some existing Eclipse based Android projects into Android Studio. Along, the way I fixed several issues and I am hitting this one last issue (hopefully):
Execution failed for task ':myapp:transformClassesWithJarMergingForDebug'.
> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/mypackage/myapp/BuildConfig.class
Here are dependencies:
module1:
dependencies {
provided files('src/main/libs/opencv.jar')
}
module2:
dependencies {
compile files('libs/autobanh.jar')
compile files('libs/libjingle_peerconnection_java.jar')
}
module3:
dependencies {
compile 'com.google.code.gson:gson:2.2.1'
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.google.android.gms:play-services:+'
compile files('src/main/libs/gcm.jar')
}
module4:
dependencies {
compile project(':module3')
compile 'com.google.android.gms:play-services:+'
}
Finally the App:
dependencies {
compile project(':module1')
compile project(':module2')
compile project(':module3')
compile project(':module4')
compile 'com.android.support:support-v4:23.4.0'
compile files('libs/AndroidSwipeLayout-v1.1.8.jar')
compile 'com.android.support:appcompat-v7:23.4.0'
}
How do I fix this? I tried the following so far:
transformClassesWithJarMergingForDebug,com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry:
Execution failed for transformClassesWithJarMergingForDebug'. (Volley)
with no help. Any thoughts?

The error says
duplicate entry: com/mypackage/myapp/BuildConfig.class
BuildConfig is a class generated for each module (Android library or application) according to package name specified in its manifest.
Make sure all your modules have a unique package name in their AndroidManifest.xml

i have tried many available solutions but nothing is working.Any help will be appreciated.

After hours with the same problem i found the answer.
The problem is that you have multiple libs with the same classes inside, so the solution would be to either remove the repeating files from one of the libs.
You have to:
Open the lib libGoogleAnalyticsServices.jar with WinRAR, 7Zip or whatever.
Go to com/google/android/gms/analytics/internal and delete the files Command$1.class and Command.class.
In your case you may have to remove other repeating files, not sure because you have many files. Either way, you can also force it to ignore some of those files IF the method above didn't work. Put the following code inside the Android block on your build.gradle file:
defaultConfig {
multiDexEnabled true
}
dexOptions {
preDexLibraries = false
}

Android Studio: Multiple dex files define Lcom/sun/activation/registries/LineTokenizer;

Receiving this exception whilst trying to build my project. Have searched around for an answer but most cases seem to be different to mine.
Other solutions include clearing temporary files or doing a gradle clean. This does temporarily solve the issue but it reappears again after a few builds. Another way this issue can occur is if the project contains multiple copies of a library. I have searched through my project and only have one instance of activation.jar which is in my libs directory. Most other solutions seem to involve changing the build path in Eclipse, but my problem is occurring on Android Studio 0.5.8. I am using Java 1.7.

Turns out this is due to a bug with the Android Gradle plugin's incremental dex option on version 0.10.2 (https://groups.google.com/forum/#!topic/adt-dev/6KbhReCE_fo). Removing the following from my build.gradle file solved the issue:
android {
dexOptions {
incremental true
}
}

As #Marepork anwered there is a bug withing gradle that has not been fixed
If you still want to use incremental build you can always use build variants and fordebug use multidex and for release a proguard

App with Google Maps doesn't build in Android Studio

I'm trying to build an app with Google Maps but whenever I try to run it there's an error message. I've added the following code to my build.gradle:
dependencies {
compile 'com.google.android.gms:play-services:4.2.42'
compile fileTree(dir: 'libs', include: ['*.jar'])
}
And here's the error message:

When I delete the code in build.gradle it runs fine, but then Maps won't work of course ;). This isn't just the case with Play Services but it does the same thing when I try to add the Support Library.
Does anyone know something that could help me solve the problem?

When using Gradle, don't include android-support-v4 by including the jar file directly; if you do it this way, the build system isn't able to disambiguate multiple copies of the support library it may encounter through direct or transitive dependencies, and you get exactly this error. Instead, remove the jar from your libs directory and include it by supplying its Maven coordinate in the dependencies block of your build file:
dependencies {
compile 'com.google.android.gms:play-services:4.2.42'
compile 'com.android.support:support-v4:+'
compile fileTree(dir: 'libs', include: ['*.jar'])
}
