A short history. please bear with me :)
I have an Android project that uses JNI which works very good.
I've decided to create out of the source of this jni project an external jar (for distribution)
In order to create this jar I've taken the advice of others and created a new Java project that holds the few jni classes I need to store in the jar. I've exported this java project to a jar (not as a runnable jar)
I've created a new Android Project in which I try to use the jar file in question.
After I've played with this new android project I came to realize that the .so file which should accompany the jni classes can't reside inside the jar file itself (Eclipse complained about it..) So I've created a lib directory inside the new Android Project which holds the .so file.
When I run this new Android project I can't work with any of the classes which has native methods, And I can only work with those classes which are pure java implementation.
I keep getting "ExceptionInInitializerError" when trying to create an instance of one of jni based objects.
Update:
It seems that the error comes from trying to load the jni library in line
System.loadLibrary("lib-jni");
Here is the logcat:

A few pointers:
I can see the .so file inside the .apk file.
I've tried defining the external jar file in the JNI Android.mk but nothing exciting happened. here are the lines I used (it compiled without a problem..)
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := libtestjar:lib/testJar.jar
include $(BUILD_MULTI_PREBUILT)
I'm able to work with regular java classes that exist only in jar file. (I know I'm repeating myself.. :) ) which means I've correctly defined this jar in the project.
The java project that holds the jni based classes has a reference to the android.jar (sdk level 7)
Does anyone has any suggestions has to how this task can be accomplished? I feel like I'm almost there...
Thank you for your time and effort :)

In the android project, did you put your .so files under lib/armeabi ?
by the way, i have the same setup as you (java project that builds a jar and an android project that uses the jar).
I managed to package the .so files in the jar ... here's what I did:
-when building the library JAR, I zip the .so files into a file (say armeabi.zip) and put it inside an 'assets' folder in the jar.
-when building the android project, the armeabi.zip will be in the 'assets' folder inside your apk.
-at runtime (first start) I extract the contents of armeabi.zip from the assets into "/data/data/" + context.getPackageName().
-finally load the extracted .so libs using System.load(/data/data//libfilename.so)
hope this helps.

Looks like an error log call is missing a message.

I'd like to import (and use) the Google Play Services library into an existing Android project, but I am struggling with what must be a dependency problem.
All documentation written by google is based upon Eclipse. We use IntelliJ IDEA.
Things I know:
I know how to import Modules, Libraries, add Dependencies, etc. in IntelliJ.
I also know that according to the getting started guide at Google, you have to add the google-play-services-lib into (Eclipse) as a project (by importing existing code into the workspace), and that you can do this in IntelliJ by adding a new module from existing code. It's the same procedure, different name.
I also understand what the Order and Export tab does in Eclipse (IntelliJ does it too).
Things I've done:
I copied (for safety) the google-play-services_lib folder from the Android SDK to my project root. So I have /myprj and /google-play-services_lib at the same level (I also have /facebooksdk and /actionbarsherlock at the same level) and proceeded to "Import Module" (from existing source). Then clicked next next next… (it worked, it was recognized).
The project structure looks like this (name intentionally blurred):
This correctly added a module (as you can see in the above screenshot). Now I need to add the dependency so my main project knows about this. I go to my modules and in the list, select my main module and then dependencies tab. I can see a few libraries (Joda time, android-query, gson, etc.) and two modules: FacebookSDK and actionbarsherlock. So far so good. And this is when things get weird.
Dependencies I've tried to add.
NOTE: In most cases I tried checking and unchecking the export checkbox and also tried adding this to the sherlockbar module at the same time, just for testing. I know these are a lot of combinations, but oh well.
1) Add a Jar or directory (knowing this was wrong, I tried). and pointed to the .jar that is inside the google play module /libs, named: google-play-services.jar.
2) Add a Library (and then adding it to the project(s))
3) Add the Module Dependency, (while having my main project selected). This shows you a pop-up like this:
PROBLEM
Even tho I can reference a PlusClient and I get the right imports, when I try to add a SignInButton in my layout xml, I get an error.
There's no point in pasting the whole XML Layout because it doesn't have anything strange, it's just a RelativeLayout with a few textviews. I added the g+ button like this:
<com.google.android.gms.common.SignInButton
android:id="#+id/sign_in_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/logo_login"
android:layout_marginBottom="30dip" />
Just like Google says.
The first sign that something may be out of order is the fact that IntelliJ warnings you that the element is "not valid here", but I assume that's a limitation of the visual designer rather than a real problem.
However, when I run the project, I get this:

If I remove the code from the Layout, it works.
My idea is that this has to do with the way Android handles the R(esources) and therefore it may not be finding the resource for the button.
Has anybody managed to use: Intellij Idea (12+) with ActionbarSherlock and Google+ Library?
If so, how? :)
For historical reasons, I'm going to reproduce what I did, taken from here. Many thanks to #Hesam who found it. I will vote to close the whole question.
Note: the shortcuts are for OS X and Intellij 12 and 13.
Make sure you have the latest SDK/ADT Tools and the play services. They change every now and then and are usually not backwards compatible.
UPDATE I had to do this again, so this is the polished version of what I did.
You need to have a copy (as opposed to using it directly from the SDK folder), because if Google updates it, things are going to break when you update your SDK, it's safer to keep a copy (albeit more tedious because you will have to manually update when a new version comes out). I found out that it's better to decide when to update than to be surprised with cryptic compilation errors.
With that in mind, copy the library alongside your project. You should have a folder structure that looks like:
/something/yourmainmodule/
/something/any_other_module/
/something/modules.xml
/something/README.md (if you use github) :)
The library is located in
"ANDROID-SDK"/extras/google/google_play_services/libproject/google-play-services_lib
ANDROID-SDK is wherever you stored the SDK when you downloaded it. Google changes this every now and then, so just find it, it will be there.
Copy that entire folder so your project now looks like this:
/something/yourmainmodule/
/something/any_other_module/
/something/google-play-services_lib/ <-- THIS IS THE NEW ONE
/something/modules.xml
/something/README.md
Good, now let's import it to IntelliJ-IDEA the right way:
1) Select your project/main module from project panel (⌘ 1) and hit ⌘ ↓ in order to open project structure window or just do File -> Project Structure.
2) Select Modules from left panel, then hit + button (or ⌘ N) then select "import module" and navigate to the google-play-services_lib that you just copied next to your project's module folder. (/something/).
The wizard will ask a series of questions, just hit next, defaults are fine, but read what's going on, understand what's happening, this is a core concept in Java, Android and Intellij. Experiment if you don't know what each dialog is saying (or why some may be empty).
After you're done, the google play Project will be added to Modules alongside with your project.
Don't close this window (or open it again if you did).
3) Still in the modules, select your project/module, then select "Dependencies" from right panel (it's a tab) and finally Click + button at the bottom (or ⌘ N which will work if you have the focus in this tab), then from the popup chose "3 Module dependencies..." and select "google-play-services_lib", which you added in the previous step. It should be there. If it's not, you didn't add the module in step 2.
4) Finally, Click + button again (or ⌘ N) but this time select "1 jars or directories...", navigate to the "/libs" folder of the above path and select "google-play-services.jar".
5) Click ok and close project structure window.
If you did this, your main module should have a dependency that looks like this:
Also make sure that in the Project Structure window, FACETS Tab, the Google Play Services has the "Library Module" checked. It is a library module.
Note: Make sure you have not added "google-play-services_lib" project as library in "Libraries" (left panel under Modules). If you have, you can go to "Libraries and simply remove it. Google Play Library Should Not Appear In Libraries.

I've never had this problem before, and i'm not experienced yet in "reading" Stacktraces, so i'm pretty much puzzled at this. If anyone has some pointers or solution i'd appreciate it.
Thanks.
Gonna copy this from another question as I had the exact same problem before, and this is how I fixed it:
If you're running adt rev 22, you might not be exporting your libraries. I don't know why
Google did this exactly, but in the newest revolution you have to
check to make sure you're exporting your libraries yourself.
Right click your project, click Properties, and check Order & Export
under Java Build Path. It should look like this if you want to export
everything:
Afterwards, rebuild the application and export it again. It should be working now. To test, simply install the .apk to your phone manually before putting it on the store to make sure it works.
ClassNotFoundException indicates that something is missing on the classpath. Maybe you are missing a library in the classpath.
As the name suggests classNotFoundException in Java is a subclass of java.lang.Exception and Comes when Java Virtual Machine tries to load a particular class and doesn't found the requested class in classpath.
Maybe you change your package name while signing your apk.
Check your package and class name
From Eclipse I righ cick the project, export the Android application and sign with a self generated keystore.
After export, occasionally I observe the APK file size is lesser than what I get normally.
When the APK file size is incorrect I encounter CNF exception for my application class i.e. DataSystem.
I extracted both correct & incorrect APKs.
With the help of dex2jar utility I converted the classes.dex to classes_dex2jar.jar and opened in java decompiler (jdgui).
I observe parent is clubbed with one of the child package and hence the other child classes of the parent does not exists.
Due to an incorrect packaging I face ClassNotFoundException on the launch of application.

As a precautionary measure, at the time of build I always observe the size of the APK if it is not normal I re-build it. But as my application is in development phase, the components are added/removed quite frequently and hence I do not have a fixed standard size to compare against, so to use this precaution is not practically possible always.
Is this a bug with ADT plugin? Please note, I am using latest revision i.e. 21.1.
Any help would be really appreciated.

Any idea how to fix this?
Is the library being exported along with the rest of your code? Assuming you're using Eclipse, If you right click on the project -> Properties -> Java build path -> Go to the "Order and Export" tab and make sure the Jama library is checked.
If it's not, the library isn't included with the rest of the project when it is built, which is usually what leads to things like "Class not found" errors.

Does anyone out there know what I did wrong?
The author of the article, Andy McFadden, give me a tip:
It's trying to create a .odex file in /data/dalvik-cache. You'll
need to be running as root, or have an unprotected
/data/dalvik-cache.
Once I rooted my device (e.g. using SuperOneClick), it worked!
Comment by #domen: You don't actually have to be root. You can set ANDROID_DATA environment variable and it will put cache there. I.e. mkdir /data/local/tmp/dalvik-cache, export ANDROID_DATA=/data/local/tmp.
It seems like you are trying to run it as a jar file from the sdcard. You need to use the tools to build it as an apk file. This converts from Java bytecodes to Dalvik codes, and reorganizes the contents of the file.
