현재 어플을 하나 만들고 있습니다. 초보인지라 이렇게 질문 올립니다.

한 어플을 실행시키고 버튼을 누르면 패키지 명으로 다른 어플을 삭제하기를 구현하려고 하는중입니다.
(어플이 어플을 삭제)
검색해서 설치하는것을 찾아서 응용을 해보았는데요.. api도 볼줄 모르는 초보라 이렇게 질문올립니다.

public class apptest extends Activity {
 /** Called when the activity is first created. */
 Button button1;
 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);
  
        button1 = (Button)findViewById(R.id.btn1);
        findViewById(R.id.btn1).setOnClickListener(mClick1);
}
    Button.OnClickListener mClick1 = new View.OnClickListener() {
   
   @Override
   public void onClick(View v) {
    // TODO Auto-generated method stub
    switch(v.getId()) {
    case R.id.btn1 :
     Intent intent = new Intent(Intent.ACTION_DELETE);
     intent.setPackage("app.test.test2"); 
     startActivity(intent);
//     finish();
    }
    
   }
  };
}
