I am just getting started towards android and i am having trouble with my hello world app, The problem is first it said R cannot resolved which i was able to overcome because there was no R.java files which i later copied from the internet now there are three errors 1. activity_main cannot be resolved or is not a field 2. menu cannot be resolved or is not a field 3. action_settings cannot be resolved or is not a field
I have already tries control+shift+o, already tried clean and build.
package my.hello;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class MainActivity extends Activity {
@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);
}
