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

Following the example provided here:
https://developers.google.com/gmail/api/v1/reference/users/messages/send#examples
email.setText() throws a NoClassDefFoundException:

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'.
> com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/mimetypes.default

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.

It's not application error.
The bug is all report from the device of sdk 22. But the method is already rename in that version.
I send email to google developer who rename the method from callDrawGLFunction to callDrawGLFunction2. I got some reply:
"Api21CompatibilityDelegate means webview believes it's running on 21. Renaming callDrawGLFunction happened after API21, hence webview is trying look for the old name."
So It's obvious device rom bug.

here is my contents of cmudict-en-us.dict
HELLO HH AH L OW
HELLO(2) HH EH L OW
HIMANSHU HH AH M AE N SH UW
and i set my keyphrase as
private static final String KEYPHRASE = "hello himanshu";

Words are case-sensitive. Your keyphrase must be in uppercase as in the dictionary. Or words in the dictionary must be lowercase. Phonemes must be in uppercase.
To debug errors like this you can read logcat output, it provides detailed messages about the problem.

String length errors with an Android Content Provider Authority string

The original name of the content provider authority that works fine with no errors:
public static final String AUTHORITY = com.dakotastream.cardiologger.CardioLoggerProvider12;
I want rename my authority to:
public static final String AUTHORITY = com.dakotastream.cardiologger.CardioLoggerProvider;
When I change the name to the above I get this error.
Caused by: java.lang.StringIndexOutOfBoundsException: length=68; index=70
public static final String AUTHORITY = com.dakotastream.cardiologger.CardioLoggerProvider1;
When I change the name to the above I get this error.
Caused by: java.lang.StringIndexOutOfBoundsException: length=69; index=70
If I rename the package to com.dakotastream.cardiologger12, then I can use the
public static final String AUTHORITY = com.dakotastream.cardiologger12.CardioLoggerProvider;
with no errors.
The Authority seems to require a string length greater than 69 characters.
I am using SDK Tools 22.6.3, API 19, ABS Library 4.4.0
I have tried creating a new Android Application Project and dropping the code in. I get the same error.

In Eclipse I use Android Tools>Rename Application Package to change the name.
This is the error I get when I change the name.

Update the android:authorities tag accordingly for the provider in the manifest.

Android in-app purchase flow broken

I'm trying to make in-app purchase flow work in my app. I use helper classes from http://developer.android.com/training/in-app-billing/preparing-iab-app.html (IabHelper etc.). Everything's fine until I make payment. When returning to activity, this exception is raised

I found that activity that started the purchase may be destroyed, what should I do in that case?
Any suggestions?

call that purchase activity using calling activity for result concept.check whether the result at onActivityResult() function using RESULT_OK and RESULT_CANCELLED so you find out.
