Error NoClassDefFound on Android

[pompobit]

I'm trying to use these API on Android, I built the bundle, imported in the project and added compile files('libs/PokeGOAPI-Java_bundle-0.0.1-SNAPSHOT.jar') on gradle.build (I'm on Android studio).
I can correctly build my project and run it, but at runtime when I try to log in (both with PTC and Google) the app crashes.
Here's the log:

java.lang.RuntimeException: An error occurred while executing doInBackground() at android.os.AsyncTask$3.done(AsyncTask.java:309) at java.util.concurrent.FutureTask.finishCompletion(FutureTask.java:354) at java.util.concurrent.FutureTask.setException(FutureTask.java:223) at java.util.concurrent.FutureTask.run(FutureTask.java:242) at android.os.AsyncTask$SerialExecutor$1.run(AsyncTask.java:234) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1113) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:588) at java.lang.Thread.run(Thread.java:818) Caused by: java.lang.NoClassDefFoundError: Failed resolution of: LPOGOProtos/Networking/EnvelopesOuterClass$Envelopes$RequestEnvelope$AuthInfo; at com.pokegoapi.auth.GoogleLogin.login(GoogleLogin.java:78) at com.acatch.pompomon.pokemon.MainActivity$Login.doInBackground(MainActivity.java:98) at com.acatch.pompomon.pokemon.MainActivity$Login.doInBackground(MainActivity.java:56) at android.os.AsyncTask$2.call(AsyncTask.java:295) at java.util.concurrent.FutureTask.run(FutureTask.java:237) at android.os.AsyncTask$SerialExecutor$1.run(AsyncTask.java:234)  at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1113)  at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:588)  at java.lang.Thread.run(Thread.java:818)  Caused by: java.lang.ClassNotFoundException: Didn't find class "POGOProtos.Networking.EnvelopesOuterClass$Envelopes$RequestEnvelope$AuthInfo" on path: DexPathList[[zip file "/data/app/com.acatch.pompomon.pokemon-2/base.apk"],nativeLibraryDirectories=[/data/app/com.acatch.pompomon.pokemon-2/lib/arm, /vendor/lib, /system/lib]] at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:56) at java.lang.ClassLoader.loadClass(ClassLoader.java:511) at java.lang.ClassLoader.loadClass(ClassLoader.java:469) at com.pokegoapi.auth.GoogleLogin.login(GoogleLogin.java:78)  at com.acatch.pompomon.pokemon.MainActivity$Login.doInBackground(MainActivity.java:98)  at com.acatch.pompomon.pokemon.MainActivity$Login.doInBackground(MainActivity.java:56)  at android.os.AsyncTask$2.call(AsyncTask.java:295)  at java.util.concurrent.FutureTask.run(FutureTask.java:237)  at android.os.AsyncTask$SerialExecutor$1.run(AsyncTask.java:234)  at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1113)  at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:588)  at java.lang.Thread.run(Thread.java:818)  Suppressed: java.lang.NoClassDefFoundError: POGOProtos.Networking.EnvelopesOuterClass$Envelopes$RequestEnvelope$AuthInfo at dalvik.system.DexFile.defineClassNative(Native Method) at dalvik.system.DexFile.defineClass(DexFile.java:226) at dalvik.system.DexFile.loadClassBinaryName(DexFile.java:219) at dalvik.system.DexPathList.findClass(DexPathList.java:338) at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:54) ... 11 more Suppressed: java.lang.ClassNotFoundException: POGOProtos.Networking.EnvelopesOuterClass$Envelopes$RequestEnvelope$AuthInfo at java.lang.Class.classForName(Native Method) at java.lang.BootClassLoader.findClass(ClassLoader.java:781) at java.lang.BootClassLoader.loadClass(ClassLoader.java:841) at java.lang.ClassLoader.loadClass(ClassLoader.java:504) ... 10 more Caused by: java.lang.NoClassDefFoundError: > > Class not found using the boot class loader; no stack trace available

So it seems it cannot find anything of POGO library (at runtime, at build time everything is fine).
I'm not sure but searching around seems like it could something related to DeX: http://stackoverflow.com/questions/28283688/noclassdeffounderror-for-jar-library-at-runtime-in-android-studio but I don't know which modules are defined as Application (I guess there aren't).

So, any idea?
And keep up the good work, if I'll find some time I'll contribute too

Should be fixed in #46 when the server will be stable for testing and merging.

Or you could just build the lib yourself by replacing compileOnly to compile in the gradle build file for the protobuf dependency.

I'm looking into #46 but I don't understand, in what way is related to my issue?

Check that line of the commit.

Is this issue still occurring on latest commit @pompobit

[pompobit]

@Grover-c13 I can't check now, I will be able to do it in a few hours

@Grover-c13 I can confirm that the issue is gone, thanks
