Question

I am using getHotelName() and setHotelName() to store data in the application and then access it. In my main activity that is categorized as Launcher both the methods and the getApplication() works in this activity. But when I try to access the getApplication from a different activity which is called from the main activity it gives a force close error.

This is my manifest file :

<application android:icon="@drawable/icon" android:label="@string/app_short_name" android:name="RestaurantNetwork" android:allowClearUserData="true" android:theme="@android:style/Theme.Black" >

    <activity android:name="RestaurantActivity"
              android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <activity android:name="NetworkCommunication"></activity>

    <uses-permission android:name="android.permission.INTERNET" />

</application> 

In the main activity

RestaurantNetwork application = (RestaurantNetwork) getApplication();
application.setHotelName(this.hotelname.getText().toString());
Intent intent = new Intent(view.getContext(), NetworkCommunication.class);
startActivity(intent);

In the NetworkCommunication activity

public class NetworkCommunication extends Activity {
RestaurantNetwork application = (RestaurantNetwork) getApplication();
String hotelname = application.getHotelName().toString();

    @Override
    public void onCreate(Bundle savedInstanceState) {

Answer 1

I solved it using intent.extra, yes i had to get rid of the getApplication(). Would still like to know why there was an error in the prev method

in my main activity

    this.hotelname = (EditText) findViewById(R.id.HotelName);

//RestaurantNetwork application = (RestaurantNetwork)getApplication();
//application.setHotelName(this.hotelname.getText().toString());

 Intent intent = new Intent(view.getContext(), NetworkCommunication.class);
 intent.putExtra("hotelName",this.hotelname.getText().toString());
 startActivity(intent);

in my second activity

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.searchresults);

        String value = null;

        Bundle extras = getIntent().getExtras();
        if(extras !=null)
        {
          value = extras.getString("hotelName");
        }

        Toast.makeText(getApplicationContext(),value, Toast.LENGTH_SHORT).show();
