1. What is the good

Programming more efficient

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::startActivity@android.content.Intent")
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);
