At Following line :-
private GoogleAccountCredential credential;
credential = GoogleAccountCredential.usingOAuth2(MainActivity.this,
DriveScopes.DRIVE);

You need to add the Google Play Services jars to your project, as explained in Step 3 of the quickstart guide you are following.
You can also watch this video where I go through all the steps to build the same quickstart application for Android: http://www.youtube.com/watch?v=Ied1CjJ0iP0

Your problem is with:
Caused by: java.lang.UnsatisfiedLinkError: Couldn't load lept: findLibrary returned null
You need to include the 'lept' jar and native c++ files in your project and reference them in your build path.
Also, take a look at best OCR (Optical character recognition) example in android

NDK App Crashing After Uploading on Play Store

I uploaded an app to the playstore. The app contains native C code. I compiled it successfully using NDK, created the signed apk. I also installed the signed apk and checked. Everything worked fine.
After uploading it I downloaded it from playstore and it crashed.
Following is the stack trace:

The error states that System.loadLibrary returned null. But the same code when run using eclipse works fine.
Thanks for any help
Seems like your apk is missing libhello-jni.so. Maybe it was not packaged during apk build.
If you open your apk with a zip software, you should have a folder libs containing libhello-jni.so : if you don't have it, then you forgot something at build time.

DownloadManager was added on API level 9 (aka Gingerbread).
My guess you declared minSDK as lower than 9 in your AndroidManifest.xml
If that is the case, you need to devise a workaround for users using older Android version.
You can check on which version your app is running by using the following code:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.GINGERBREAD) {
// Use DownloadManager
}
else {
// Workaround
}

Running Barcode Scanner App from ZXing Source?

I'm trying to make a restricted version of barcode scanner, which can only scan 2d data matrices. I figured the best way to do this would be to get the latest source from ZXing svn repository, build the core.jar, include it in the app lib, and work from there.
However, to see how various components in the app work I tried to run the barcode scanner app using the android source code in the ZXing repository. To do this I followed instructions given on
https://stackoverflow.com/a/4854637/1273954
https://stackoverflow.com/a/4825803/1273954
& also http://damianflannery.wordpress.com/2011/06/13/integrate-zxing-barcode-scanner-into-your-android-app-natively-using-eclipse/
All these posts inherently talk about the same thing and same approach. However, each time I run the application, my device says "Unfortunately, Barcode SCanner has stopped"
Here is what logcat shows :

The Posts also speak about modifications to the file androidManifest.xml. I have no idea what modifications to make there.
Any help or redirection or resource reference in this would be appreciated.
You're getting a NoClassDefFoundError. This means your jar file is not available at runtime. In order for it to be available at runtime you'll have to check the checkboxes on your jar file in your java build path like so:

Android - how am I supposed to fix the error based on this exception trace?

There is an error in my Android application that happens quite often, based on the crash report on the Developer Console.

Unfortunately, I can't replicate that error on my Android phone.
I dont' know where to start: in the trace there isn't any reference to my code.
Can somebody give me some suggestions on how to identify the root of the problem, please?
Thanks,
Dan
The most obvious things I can think of:
AbsListView.obtainView() I believe is communicating with the Adopter to populate the list view. Make sure there is never a case where you could return a null back to the list view.
There may be a bug in some version of the platform. Unfortunately the developer console does not currently show you the platform version the error reports came from. Hopefully this will be added in the future to help diagnose such a situation.
It is possible someone is running a non-standard or custom build of the platform that has bugs. You might be able to determine this by looking at the "platforms" section for the different devices the error is coming from.
I would try creating a virtual device and load it in the emulator, start with the smallest resolution.
I am suspecting that it has to do with screen size and somehow you are trying to draw in a pixel that doesn't exist.
