the first xml page opens up while running the app but as soon as i press the login button the app closes saying the app is not responding — Shashwat, Dec 07 '14 at 19:23
do you have anything in the second activity? if so post it ok, that's if you cool, also change the `getApplicationContext()` to `getBaseContext()` or `MainActivity.this` — Elltz, Dec 07 '14 at 19:27
Are you running `setContentView(R.layout.Activity_Second)` in your second activity? — MeetTitan, Dec 07 '14 at 19:27
@Elltz-my second activity is as simple as displaying hello world but while running the debugger window is showing resource not found — Shashwat, Dec 07 '14 at 19:36

 public class MainActivity extends ActionBarActivity { //mainactivity class

 @Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 Button button = (Button) findViewById(R.id.button_id);
 button.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        Intent i = new Intent(MainActivity.this,Second.class);
        startActivity(i);
      }
   });
 }

then your manifest

<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/Theme.Base.AppCompat.Light.DarkActionBar" > // i changed this
<activity
    android:name=".MainActivity"
    android:label="@string/title_activity_main" >
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
   </activity>
  <activity
    android:name=".Second"
    android:label="@string/title_activity_second" >
  </activity>
 </application>

if you extend actionbarActivity its xml should use its style's, i dont wona story this, so i will repharse it in my edit. simply to say your second activity doesn't have style set so it uses the device default theme for the activity set in your application so copy paste the respective codes in mine to yours

It's called ANR short for Android Not Responding. Your app is doing so much processing in the main thread. Consider using a background Thread or AsyncTask along with ProgressDialog so that the main thread is not affected by the processing part.

Read more about it in the documentation. Also refer to this post for more info.
