Reflectx

A reflection framework that uses annotations and interfaces to eliminate redundant code for reflection.

Usage demo

import android.app.Application;

import reflectx.IProxyClass;
import reflectx.annotations.Source;

@Source("android.app.ActivityThread")
public interface IActivityThread extends IProxyClass {
    IActivityThread currentActivityThread();

    String currentPackageName();

    Application currentApplication();
}

// ...

import reflectx.ProxyFactory;
import reflectx.mapping.ProxyClassMapping; // Generated by the annotation processor.

public class MainActivity extends Activity {
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // It only needs to be initialized once.
        ProxyClassMapping.init();
        // Proxy "class android.app.ActivityThread".
        IActivityThread am = ProxyFactory.proxy(IActivityThread.class);
        // Call the static method and wrap the return result.
        am = am.currentActivityThread();
        // Call the member method.
        Application currentApplication = am.currentApplication();
        Assert.assertEquals(currentApplication, getApplication());
        String currentPackageName = am.currentPackageName();
        Assert.assertEquals(currentPackageName, getPackageName());
    }
}
