restfb
RestFB is a simple and flexible Facebook Graph API client written in Java.
It is open source software released under the terms of the MIT License.

Features

restfb has been designed with several objectives in mind. The most important of these are defined as follows.

Zero runtime dependencies

You don't need to include additional libraries in your project. There are no dependency conflicts. In addition, RestFB is highly portable and can be used in both Android projects and normal Java applications.

Maximal extensibility

Although we provide a standard implementation for our core components, each component can be replaced with a custom implementation. This allows RestFB to be easily integrated into any kind of project. Even Android projects are supported.

Minimal public API

TThe RestFB API is really minimal and you only need to use one method to get information from Facebook and one to publish new items to Facebook. We provide default implementations for all the core components, so you can drop the jar into your project and be ready to go.

Simple metadata-driven configuration

Our Facebook types are simple POJOs with special annotations. This configuration is designed for ease of use and can be used to define custom types very easily.

Download

RestFB can be downloaded from Github or used as a Maven dependency. There is also a sample project on Github.

Restfb example

You can find a sample project on Github. This project can help you get up and running quickly.

Abstract The Oppo A9 (2019) occupies a strange purgatory in smartphone history. Shipped with Android 9 (ColorOS 6) and receiving only a lackluster update to Android 11 (ColorOS 11), it was abandoned long before its hardware gave out. Unlike its Snapdragon-powered cousins, the A9 features a MediaTek Helio P35 —a chipset notorious in the modding community for locked bootloaders and a dearth of source code. This paper explores the underground war to bring Custom ROMs (like GSI and Treble) to the Oppo A9, examining why users risk bricking their devices for a few extra years of life. 1. The Paradox of the "Dead" Chipset Most custom ROM communities thrive on Qualcomm chips due to readily available kernel sources. The Oppo A9’s MT6765 is a different beast. Officially, MediaTek is the enemy of the "tinkerer." However, Project Treble (introduced in Android 8) created a loophole. The Oppo A9 shipped with Treble support, meaning the vendor implementation (VNDK) is separated from the Android framework.
