adb shell am instrument process crashed

I'm trying to run an espresso black box test on a 3rd party apk file using a test apk file. I've set the testApplicationId in the build.gradle, and the targetPackage in AndroidManifest.xml.
Here's the commands I run:
adb install app-debug.apk
Success
adb install app-debug-androidTest.apk
Success
adb shell am instrument -w com.example.android.testing.espresso.WikipediaTester/android.support.test.runner.AndroidJUnitRunner
INSTRUMENTATION_RESULT: shortMsg=Process crashed.
INSTRUMENTATION_CODE: 0
Here's the tomcat log:

AVD crashes saying 'Unfortunately, libcocos2dx has crashed'

I just loaded my app created by cocos2dx-3.10 and when I open with it an AVD (again I haven't done any modifications to the app) the app crashes and gives the error: Unfortunately, libcocos2dx has crashed.
here is what I get in my android Monitor:

I'll appreciate any suggestion.

While removing different parts of the code I found that the issue was in a 3rd party library I used.
I changed its usage from "gnustl_static" version (.a) to "gnustl_shared" (.so) one and the problem disappeared!

java mail 1.4.5 on android

I'm developing a IMAP client on a custom Android device. So i decided to use the Java Mail library.
I needed to update from the 1.4.1 version of Java Mail to 1.4.5 because i had memory problem in case of huge INBOX folder (About 120k mails).
So i downloaded the 2 jars (mail.jar and activation.jar) from the official home page, i tried also with the release candidate 1.4.6 but i cannot make it works.
Once i build the entire app, everything is ok, but when i run, here's what it comes:

I tried checking the DataHandler and getName method in the jar, and everything is ok.
Is there anyone who had the same problem?
Thanks to all.

Not every java library works on Android. You can only use javamail port for android. The latest versions of Javamail have still not been ported for Android

I found the solution! I needed to modify the mail.jar and its source codes. It'a "import packaging" problem. In the Android porting, some of the mail.jar classes, import other classes from the additionnal.jar in which the package name is myjava.awt. exc.
In java mail 1.4.5 that package is named java.awt exc, withouth the "my" prefix. Fixing that, all will work.
Thanks to all!

you hadnt built the library(.so) file of the project thats why you are getting this error, try to build the project with help of android-ndk http://developer.android.com/sdk/ndk/index.html and cygwin http://www.cygwin.com/
