I built a test project to learn how to use toobar in support library.
It's a simple page with an action bar at the top of the page.
MainActivity is extending AppCompatActivity.
I'm using eclipse. Developed in android 6. and when I run it on the android 6 emmulator, it's working fine. but when I try to run the same code on android 5 emmulator, it crashes with following error messages

Here's my mainactivity.java
package com.beantownloner.babyshoppinglist;
import com.beantownloner.babyshoppinglist.R;
import android.support.v7.app.AppCompatActivity;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
I've spent days to set up the support library and use it, but really can't get it working in previous versions of android.
