You can can create a "BaseActivity" and include a lot code in that single class and then simply create classes and extend that "BaseActivity".

Here is what I think you are looking for:

public class BaseActivity extends Activity {

public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu, menu);
    return true;
}   

public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()){

    case R.id.donate:  
        //something
        break;

    case R.id.about_menuitem:  
        //something
        break;

    case R.id.exit:  
        finish();
        break;         

    default:
        return true;
    }
    return true;
}   
}

I created a class called "BaseActivity", in this class I have my Android options menu and I also extend "Activity". Since I extended "Activity" and have my options menu in this class, I can now use this same menu code for all my other classes.

I just simply create my new classes and extend them with "BaseActivity":

public class SomeOtherActivity extends BaseActivity {
 //new code here
}

Now the class called "SomeOtherActivity", will inherit my menu code and also "Activity".

Please try this out and let me know is this helps!

the solution is simple: extends the class Activity, and add him all the methods you want. (I usually call this class BaseActivity for instance)
then, when you are developing new activity - instead of extend the class Activity - extends the class BaseActivity you've made, which contain the methods you added..

public class BaseActivity extends Activity
{
protected int mSomeValue;

protected void someMethod1()
{

}

protected void someMethod2()
{

}

protected void someMethod3()
{

}

}

class SomeActivity extends BaseActivity
{
@Override
protected void onCreate(Bundle savedInstanceState)
{
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    someMethod1();
}
}

class SomeActivity2 extends BaseActivity
{
@Override
protected void onCreate(Bundle savedInstanceState)
{
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    someMethod1();
}
}
