Proguard issue when trying to login with Firebase UI Auth

I am using Firebase UI Auth to login into the application. The debug build is working fine but when I try to login with the release build the application crashes with an error.

What could be the possible reason for this?

Malformed exception in fabric library

Recently I see an exception in my log that fabric (Beta) tries to check for updates and this is the error:
E/Beta: Error while checking for updates from null
io.fabric.sdk.android.services.network.HttpRequest$HttpRequestException: java.net.MalformedURLException: Protocol not found: null?instance=
I don't know why fabric tries to check for updates with a null URL, but I really want to remove that error.

I solved a lot of errors logs and the exception above by updating the crashlytics library version.

I also have solved this issue updating Crashlytics version in /app/build.gradle file.
I leave here the code of the fix for convenienece:
dependencies {
compile('com.crashlytics.sdk.android:crashlytics:2.9.4#aar') {
transitive = true;
}
}

No implementation found for com.djinnius.HelloWorld$CppProxy

I'm working on a React Native project that uses djinni to use cross platform native C++.
I already looked at this question, but it seems a different problem.
The project build successfully but fails almost immediately on run.
adb logcat shows the following exception:
No implementation found for com.djinnius.HelloWorld$CppProxy com.djinnius.HelloWorld.create(com.rushingvise.reactcpp.ReactBridge) (tried Java_com_djinnius_HelloWorld_create and Java_com_djinnius_HelloWorld_create__Lcom_rushingvise_reactcpp_ReactBridge_2)
I'm trying to understand what tried means in the message above. Is this because the corresponding native code is missing from the apk ? Or maybe another cause ?
Full logcat is following:

Found the problem.
It was indeed a missing System.LoadLibrary() Call in the Java Class extending ReactPackage.
This is working now with this class initializer
public class HelloWorldPackage implements ReactPackage {
static {
System.loadLibrary("native-lib");
}

Watson Developer java-sdk STT

Getting this error in sample app.
java.net.ProtocolException: Expected HTTP 101 response but was '401

Using this code snippet to transalate.
TranslateOptions translateOptions = new TranslateOptions.Builder()
.addText(params[0])
.source(Language.ENGLISH)
.target(selectedTargetLanguage)
.build();
TranslationResult translationResult = translationService
.translate(translateOptions)
.execute();
Once it executes the application crashes and I see this error in logs.

i don't know too much about how watson sdk works but just by looking at the error i see:
com.ibm.watson.developer_cloud.service.exception.UnauthorizedException:
Unauthorized: Access is denied due to invalid credentials. Tip: Did
you set the Endpoint?
Is saying the credentials presented are not valid. You should start by looking at that.

NoClassDefFound when using MimeMessage.setText(), for Gmail API in android

Finding solutions in the following links:
java.lang.NoClassDefFoundError: javax.activation.DataHandler
java.lang.NoClassDefFoundError: javax.activation.DataHandler in android
I understand that this exception is due to android not implementing java.awt.datatransfer classes. I tried the solutions but they didnt work. When i added javax.mail 1.5.5 in gradle it shows a duplicate file copied error.
Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'.

I couldnt find any solutions for this. I tried excluding excluding file in gradle packaging options, it didnt work only throwing NoClassDefFound exception again.
Any help would be appreciated.
