Android Studio dex.DexException:

Randomly got this error during my build (debug or production) in the morning.
com.android.dex.DexException: Multiple dex files define Lcom/crashlytics/android/answers/shim/R
Execution failed for task ':app:transformClassesWithDexForDebug'.

It has been 10hours and I have tried:
1) Updated my Android SDKs
2) Updated my Google Repository
3) Updated everything else as well.
4) Cleaned and Rebuild the project with no errors.
5) Went through my external dependency tree, didn't find any duplicate libraries.
Here is my gradle content:

Running out of ideas and google result pages for a solution. Does anybody experienced find something wrong with the libraries I use or the versions?
Thanks!

remove this line = compile 'com.android.support:design:25.0.0'
if it doesn't work please add
dexOptions {
preDexLibraries = false }
to your build.gradle file

Solution found.
Looking at the error I googled and found this.
Then went to the Branch documentation and found this here which stated:
Note that if you don’t plan to use the Fabric Answers integration, you
can use the following line:
compile ('io.branch.sdk.android:library:2.+') {
exclude module: 'answers-shim'
}
This answers-shim is also in the stacktrace.
I wonder where is that module then duplicated?

Android Error duplicate entry: com/google/android/gms/internal/zzai$zza.class

I am currently having some trouble running my project.
duplicate entry: com/google/android/gms/internal/zzai$zza.class
The error is saying that I have a duplicate dependency, but I can't see a duplicate anywhere!
The error appears on this line of code:
compile 'com.google.android.gms:play-services-ads:8.4.0'
It says that it has found versions 9.8 and 8.4. I only see version 8.4 though.
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.3"
defaultConfig {
applicationId "com.tedrasoft.templategoogle"

}

}
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile files('libs/chartboost.jar')
compile 'com.android.support:appcompat-v7:23.3.0'
compile 'com.google.android.gms:play-services-ads:8.4.0'
compile 'com.facebook.android:facebook-android-sdk:4.+'
compile 'com.facebook.android:audience-network-sdk:4.+'
compile 'com.onesignal:OneSignal:2.+#aar'
compile 'com.google.android.gms:play-services-gcm:8.4.0'
compile 'com.google.android.gms:play-services-analytics:+'
compile 'com.google.android.gms:play-services-location:+'
compile files('libs/jackson-annotations-2.1.0.jar')
compile files('libs/jackson-core-2.1.0.jar')
compile files('libs/jackson-databind-2.1.0.jar')
}

In my case, it's because of the
compile 'com.facebook.android:audience-network-sdk:4.+'
I change it to this:
compile ('com.facebook.android:audience-network-sdk:4.+'){
exclude group:"com.google.android.gms"
}
No more problem!

Make these versions match... so 8.4.0, not + which pulls the latest 9.8 I think, now?
compile 'com.google.android.gms:play-services-analytics:+'
compile 'com.google.android.gms:play-services-location:+'
Also, these are 1) unneccessary lines (because of compile fileTree), and 2) you should make them like the others and not use jar files.
compile files('libs/jackson-annotations-2.1.0.jar')
compile files('libs/jackson-core-2.1.0.jar')
compile files('libs/jackson-databind-2.1.0.jar')

Upgrade google play services (maps, location and gcm) from 9.0.0 to 9.2.0
compile 'com.google.android.gms:play-services-location:9.2.0'
compile 'com.google.android.gms:play-services-maps:9.2.0'
compile 'com.google.android.gms:play-services-gcm:9.2.0'
Then add this dependency:
compile 'com.google.android.gms:play-services-places:9.2.0'

please help me to solve this problem. Thank you anyway

Please change your gradle dependencies as following :
compile 'com.android.support:support-v4:23.0.1'
compile 'com.google.code.gson:gson:2.3.1'
compile 'com.google.android.gms:play-services:+'
compile 'com.android.support:appcompat-v7:23.0.1'
compile files('libs/renderscript-v8.jar')
compile files('libs/sun.misc.BASE64Decoder.jar')
compile 'org.apache.httpcomponents:httpclient:4.2.3'
compile 'org.bouncycastle:bcprov-jdk15on:1.47'
compile 'org.apache.httpcomponents:httpcore:4.3'
compile 'com.nineoldandroids:library:2.4.0'
compile 'com.pubnub:pubnub-android:3.7.2'
compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.2'
compile 'com.android.support:multidex:1.0.1'
Note :
In Gradle when we do not use gradle dependency and if our libs folder dependencies contains duplicate class then
java.util.zip.ZipException: duplicate entry
This exception occurs.
So Whenever you add dependencies then if possible then try maximum to use maven dependencies.
Thank you.!!

Try adding following dependencies:
compile 'com.google.android.gms:play-services-plus:8.1.0'
compile 'com.google.android.gms:play-services-location:8.1.0'
compile 'com.google.android.gms:play-services-identity:8.1.0'
compile 'com.google.android.gms:play-services-maps:8.1.0'
compile 'com.google.android.gms:play-services-gcm:8.1.0'
compile 'com.google.android.gms:play-services-appindexing:8.1.0'

duplicate entry: com/google/android/gms/common/SupportErrorDialogFragment.class

I am creating project in android studio with multi dex support . I am getting error : java.util.zip.ZipException: duplicate entry: com/google/android/gms/common/SupportErrorDialogFragment.class .

You have conflicting dependencies in your build.gradle, meaning multiple dependencies containing the same classes:
compile 'com.google.android.gms:play-services:+'
compile files('libs/google-play-services.jar')
compile files('libs/libGoogleAnalyticsServices.jar')
compile files('libs/gcm.jar')
All of these components are provided by Google Play Services (the first one in the list). So you should only declare Google Play Services once, preferably only the components you're using instead of the full package: See "Selectively compiling APIs into your executable" https://developers.google.com/android/guides/setup
Chances are you won't even need multidex after you simplify your project dependencies.
Also (unrelated), I'm wondering what are these dependencies, if it's the Android framework itself you can remove them:
compile files('libs/Android_SDK.jar')
compile files('libs/Android_SDK_component.jar')
