Error while using PackageManager in Android

I got a problem in one Android Application which I am working in which I am getting error when I use PackageManager.

The Application is as follows:

Home.java

package com.main.home;

public class Home extends Activity
{
    //onclicking a Button say "send"
    send.onClickListener() 
    {
        public void onClick() {
            Intent i =new Intent();
            i.setClassName("com.main.home", "com.main.home.home1");
            startActivity(i); 
    }
}

Home1.java

package com.main.home;

import com.andr.resulting.Result ;

public class Home1 extends Activity  {
    EditText et=(EditText)findViewById(R.id.e1);
    //Clicking on forwardButton in that onClick()

    public void onClick()
    {
        String s[] = {e1.getText().toString(),""};
        //Calling a method in a class Result of another package which is not activity
        Result.finalfunc(Home1.this,s);

}

Result.java

package com.andr.resulting;   //different package

public class Result {
    public static void finalfunc(Activity act,String[] re) ...
    //Here I want to get the details of this particular class's package (com.andr.开发者_Python百科resulting) using PackageManager

    // I tried like this:
    Result.this.getPackageManager().getApplicationInfo(Result.getPackageName(),0))

I am getting error getPackageManager() does not exists in this class file.

How do I solve this issue? I will be eagerly waiting for valuable reply. Thanks in Advance.

try this::

this.getPackageManager().getApplicationInfo(this.getPackageName(), 0);

Result doesn't extend Context like your Activity class does. So the method isn't available in that class. You need to call act.getPackageManager() inside there instead of this.getPackageManager().
