Hi I have updated my sdk to api level 21 and i am getting many errors from then. My simple application which didnt give any kind of errors before started giving me run time exceptions. Here is my mainactivity.java class:
package com.example.myfirstapp;
import android.support.v4.view.MenuItemCompat;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.widget.ShareActionProvider;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class MainActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
@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);
MenuItem shareItem=menu.findItem(R.id.action_share);
ShareActionProvider m=(ShareActionProvider)MenuItemCompat.getActionProvider(shareItem);
m.setShareIntent(getDefaultIntent());
return true;
}
private Intent getDefaultIntent() {
// TODO Auto-generated method stub
Intent intent=new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
return intent;
}
@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);
}
}
My Manifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myfirstapp"
android:versionCode="1"

</application>
