- Modified version available at https://android.googlesource.com/platform/external/fat32lib/
- Stackoverflow issue http://stackoverflow.com/questions/18906055/what-causes-jobb-tool-to-throw-fat-full-ioexception
(on OS X, $ANDROID_SDK is by default ~/Library/Android/sdk)
- Produce the library with
gradle jar - Archive SDK version
mv $ANDROID_SDK/tools/lib/fat32lib.jar $ANDROID_SDK/tools/lib/fat32lib.jar.orig - Put patched version in place
cp build/lib/android-sdk-fat32lib.jar $ANDROID_SDK/tools/lib/fat32lib.jar
Now jobb should work on larger folders
