- Android Support v4 (Development Framework)
requires 3 permissions: android.permission.VIBRATE, android.permission.ACCESS_NETWORK_STATE, android.permission.WAKE_LOCK 
The Android Support Library is not actually a single library, but rather a collection of libraries that can roughly be divided into two groups: compatibility and component libraries. For details, please see
Understanding the Android Support Library.
- ORMLite (Utility)
- Spongy Castle (Utility)
a collection of APIs used in cryptography, to complement the stripped-down version of
Bouncy Castle Android ships with.
- ZXing ('Zebra Crossing') (Utility)
requires 3 permissions: android.permission.WAKE_LOCK, android.permission.VIBRATE, android.permission.CAMERA
ZXing („zebra crossing“) is an open-source, multi-format 1D/2D barcode image processing library.
- FasterXML (Utility)
requires 1 permissions: android.permission.INTERNET
a fast and compliant streaming JSON parser/writer with a StAX-like API and support for marshalling/unmarshalling POJOs via annotations.
- Bouncy Castle (Utility)
