android_hidden_api

What

this project we mock Android hidden system api, so that you can use it directly in your Android app

Why

Technically, you can not use ActivityThread.currentApplication() method in your application,

because Android Team removed ActivityThread.class and other classes / methods / fields annotated by @hide when packing Android.jar. That's a very tricky way.

When you write ActivityThread.currentApplication() in your code, your IDE and compiler will complaint "Can't find ActivityThread".

But, what if we still want to use?

As we known, Those hidden classes / methods / fields can be accessed at runtime,

so we just need a little trick to cheat on compiler.

This project is the little trick.

How

In simple words, we just reverse the Android Team work.

We mock ActivityThread.class and associates as a general 3rd-party library.

The key point is to add this dependency by compileOnly.

compileOnly means I guarantee those hidden apis will be found at runtime,

the compiler will not search those in classpath any more.

// add jitpack repo
repositories {
        maven {
            url 'https://jitpack.io'
        }
 }
...


// add dependency

dependencies { 

        compileOnly "com.github.fatterx:android_hidden_api:0.0.1"
        
        

        // DO NOT ADD THIS DEPENDENCY LIKE THIS
        
        // api "com.github.fatterx:android_hidden_api:0.0.1"
        // implementation "com.github.fatterx:android_hidden_api:0.0.1"
        // runtimeOnly "com.github.fatterx:android_hidden_api:0.0.1"
        
    }
