Using Popup menu giving ClassNotFound Exception

I am using popup menu in my app and it is crashing after on click, giving ClassNotFound Exception. I had used the following code 

menu=(ImageView)findViewById(R.id.menu);
  menu.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View view) {
        // TODO Auto-generated method stub
        PopupMenu popupMenu = new PopupMenu(HTTTPGet.this, view);
        popupMenu.setOnMenuItemClickListener(HTTTPGet.this);
        popupMenu.inflate(R.menu.popupmenu);
        popupMenu.show();
    }
});

here is the onmenuitemclick method

@Override
public boolean onMenuItemClick(MenuItem item) {
// TODO Auto-generated method stub
switch (item.getItemId()) {

case R.id.home:
    Intent home=new Intent(this,HTTTPGet.class);
    startActivity(home);
    return true;
case R.id.schedule:
    Intent schedule=new Intent(this,Schedule.class);
    startActivity(schedule);
    return true;
case R.id.manual:
    Intent manual=new Intent(this,Schedule.class);
    startActivity(manual);
    return true;
default:
return false;
}
}

after clicking on imageview app is getting crashed and the logcat is

Does I need to add anything to above code?

Solution

  • PopupMenu is available from Android API 11.

    So just check your minimum SDK version in manifest file. And atleast you have to set minimum SDK version 11.

    For more information read documents http://developer.android.com/reference/android/widget/PopupMenu.html
