android - Reflection on PackageManager fails -


I am trying to reach PackageManager via reflection. I can calculate the methods and find getApplicationInfo. I can also execute getApplicationInfo on the basis of context I gets reflection through GetMethods () but getMethod () with getApplicationInfo a no such exception exception . 

  method of law; Law method 2; Method = Class.forName (Context.class.getName ()). GetDeclaredMethod ("getPackageManager"); Object manager; Manager = method.invoke (ctx); // This works ApplicationInfo testInfo = (PackageManager Manager). GetApplicationInfo ("com.package.class", 0); // throws nosuchmethodexception (PackageManager Manager) .getClass () GetMethod ("getApplicationInfo");    
 
 
 See method definition  
  public method getDeclaredMethod (string name, class ...   
 You must pass the  class  example of the parameter types.  
 Change  
  (PackageManager Manager) .getClass () GetMethod ("GetApplicationInfo");   
  
  (PackageManager manager) .getClass () GetMethod ("getApplicationInfo", int.class); < / Code>

If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea.
