Millennial Media SDK 6.4 integration in Android fails

I'm trying to integrate Millennial Media SDK 6.4 in my Android app, but it shows an error message below when I run the app on my phone.
Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.
com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/google/android/gms/gcm/PendingCallback$1.class
At first, I run the sample code with latest SDK downloaded directly from Millennial Media site, and it worked perfectly on my device. Then I migrated the inline ad code into my app following the official integration guide and there were no any problems when compiling or cleaning the project until I attempted running it in my phone. Please see my build.gradle file below.

compile 'com.android.support:multidex:1.0.1'
compile project(':android-ad-sdk')
compile 'com.google.android.gms:play-services:10.2.4'
}
I have tried cleaning gradlew, updating the gradle version and restarting the project, but nothing works. I have also contacted Millennial Media support team a day ago, though no response has been heard yet.
Have anyone seen this problem or known how to fix. Please give me any advices that I will appreciate. Or do you use other ad network providers that could be better than Millennial Media?
Cheers.
Update 1:
I've tried commenting compile "com.google.android.gms:play-services:10.2.4". Although it built the app, it showed a fatal exception below when I started the activity with the ad.

FireBase Error: cannot access zzanb class file for com.google.android.gms.internal.zzanb not found

UPD. I have read these question and answer (Class file for com.google.android.gms.internal.zzaja not found). But I doesnt understand what strings i need to add or remove in my project.
Because I havent this and other strings in my code:
compile 'com.google.android.gms:play-services-location:9.2.0'
I develop an android app with use of FireBase. And when I want to build my project I have an error:
Error:(39, 25) error: cannot access zzanb

The error was caused by invoking statement: FirebaseAuth.getInstance().getCurrentUser();

Please, help me to solve that error)
P.S I have already read that question (Firebase Error cannot access zzanb after using play-services-xxx:9.8.00), but i didnt understand anything, what i need to add or remove from my build.gradle files in my situation.

You're mixing libraries from old and new Firebase released. Everything from Firebase that you use should be in parity. This line is reference an library from a very old Firebase release (before it became the Firebase platform at Google):
compile 'com.firebaseui:firebase-ui:0.6.0'
If you want to use the Firebase-UI library, you should use the new version of it that matches the version of the main client library you're using. You're using 10.0.1, so according to the table on the Firebase-UI github I just linked, you want this dependency:
compile 'com.firebaseui:firebase-ui:1.1.1'
Always make sure your Firebase-UI library matches the core Firebase SDK you're using.

It looks like in your case Doug's fix resolved your issue, but we recently encountered the same problem with a different root cause.
In our case, we had configured our IDE project to use JDK8 but failed to check which version of the JDK was in use in the terminal. Because React Native runs Gradle from the command line when you type 'react-native run-android' Gradle was attempting to build using JDK10 which caused obvious issues since Android currently only supports up to JDK8. Once we configured the terminal to use JDK8 the issue was resolved.
TL;DR: Check what version of the JDK you are using in the terminal.

Getting following error:

I am working on a google cloud translate application.
I am getting errors.
I search and ı have try some solution but does not help me.
What isthe problem ?
My libs folder is empty.
please help me.

I had a same issue. In my app I am using guava-retrying library, which was fetching google guava library version 21. Guava version 21 requires JDK 1.8 without providing back porting support and this was causing this error in my case.
I was able to solve it by including the guava-retrying library so that it uses version 19.0 of guava library:
compile ("com.github.rholder:guava-retrying:2.0.0") {
exclude group: 'com.google.guava', module: 'guava'
}
compile 'com.google.guava:guava:19.0'
Basically you would want to check if any of your app's dependencies require JDK 1.8 to compile, and remove/downgrade them.

Compiling compatibility issue external libraries

I were trying to use the Selenium WebDriver for an Android application. (I am using the latest AndroidStudio; v2.2)
I followed this guide so in the lib's my app I copied the jar files (the downloaded zip of Selenium WebDriver has a folder named "libs", a jar named "client-combined-3.0.0-beta4-nodeps" and a DEPENDENCIES and a LICENSE file[I've just copied all the jars in the "libs" folder and the other jar outside])
Here's the build.gradle (module:app)
apply plugin: 'com.android.application'

}
}

(Project synched)
While executing "run" I had this error:
Error:Error converting bytecode to dex:
Cause: Dex cannot parse version 52 byte code.
This is caused by library dependencies that have been compiled using Java 8 or above.
If you are using the 'java' gradle plugin in a library submodule add
targetCompatibility = '1.7'
sourceCompatibility = '1.7'
to that submodule's build.gradle file.
Error:1 error; aborting

So I've gone to the build.gradle (Project: DownAll) and I added these target/source compatibility, so here's what's like:
I cleaned the project, rebuilded it, re-synched it but still the same error.
What should I do?
If it can help, here's my environment variables, if it can help:
JAVA_HOME
C:\Program Files\Java\jdk1.8.0_102
ANDROID_HOME
C:\Users\Utente\AppData\Local\Android\sdk;C:\Users\Utente\AppData\Local\Android\sdk\tools;C:\Users\Utente\AppData\Local\Android\sdk\platform-tools
(AppData folder is hidden)
EDIT:
UP

I just faced the exact same error and figured out that com.google.guava:guava:21.0 was causing the problem; app starts working right after downgrading it to 20.0.
So, I guess some of your jars might be incompatible.
Try downgrading / removing dependencies one by one.

java.lang.NoClassDefFoundError while testing a Realm app on Android 2.3.3 (API 10 Emulator)

I've been learning realm for the past few days and today I decided to test an app I'm developing on Android using Realm, for backward compatibility.
Emulator details:
Name: Nexus_4_API_10_2.3.3
CPU/ABI: ARM (armeabi)
Path: /home/mush/.android/avd/Nexus_4_API_10_2.3.3.avd
Target: default [Default] (API level 10)

hw.device.name: Nexus 4

hw.audioInput: yes
image.sysdir.1: platforms/android-10/images/
tag.id: default
showDeviceFrame: yes
hw.camera.back: emulated
hw.mainKeys: no
The App crushes as soon as it launches citing LoginActivity.java as the source of the error.
Logcat Snippet:
D/AndroidRuntime: Shutting down VM
W/dalvikvm: threadid=1: thread exiting with uncaught exception (group=0x40015560)
E/AndroidRuntime: FATAL EXCEPTION: main
java.lang.NoClassDefFoundError: _package_name_.sessions.LoginActivity
at _package_name_.SplashActivity.onCreate(SplashActivity.java:26)
at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047)
I then went ahead to comment out the snippet of code that calls the LoginActivity.java.
The snippet:
//Check whether there's an active session first
sessionManager = new SessionManager(getApplicationContext());
if (sessionManager.isSessionActive()) {
//Session is active => Launch the MainActivity
Intent launchMainActivity = new Intent(getApplicationContext(), MainActivity.class);
startActivity(launchMainActivity);
} else {
//Session is inactive => Launch the LoginActivity
Intent launchLogin = new Intent(this, LoginActivity.class);
startActivity(launchLogin);
finish();
}
This did not solve my issue. Instead, Logcat halts at this point and the app freezes at my splash screen.
Logcat:
