Legend is a Hook framework for Android Development, it allows you to Hook Java methods without ROOT. Even more exciting is that it supports both Dalvik and Art environment!

1. What is the good
- Programming more efficient
- Dynamic debugging
- HotFix and needn't reboot app
- Fast dump Dex File in the shell
- Software security penetration
- Do some exciting things...
2. How to use
Example 1: Annotation type Hook
@Hook("android.widget.Toast::show")
public static void Toast_show(Toast thiz) {
thiz.setText("XXXXXXXXX");
//Call the origin method
HookManager.getDefault().callSuper(thiz);
}
Example 2: Interception of startActivity
@Hook("android.app.Activity::[email protected]")
public static void Activity_startActivity(Activity thiz, Intent intent) {
if (!ALLOW_LAUNCH_ACTIVITY) {
Toast.makeText(thiz, "I am sorry to turn your Activity down :)", Toast.LENGTH_SHORT).show();
} else {
HookManager.getDefault().callSuper(thiz, intent);
}
}
Notice:
- Write the following code down in where you want to your hooks enable.
HookManager.getDefault().applyHooks(YourClass.class);
- You can also hook a method without annotation.
HookManager.getDefault().hookMethod(originMethod, hookMethod);
