Android custom dialog force close

Question

I am implementing a custom dialog to form an about screen with a simple look and feel (which may become more complex once I get it working). I have a xml layout that loads some text and an icon from R. However when ever showDialog(int) is called I get a force close. I followed the instructions as per the dev guide: http://developer.android.com/intl/de/guide/topics/ui/dialogs.html code is as follows: ``` @Override protected Dialog onCreateDialog(int id) { Dialog dialog; switch(id) { case DIAG_ABOUT: dialog = new Dialog(getApplicationContext()); dialog.setContentView(R.layout.aboutdialog); dialog.setTitle(R.string.about_title); dialog.setOwnerActivity(this); break; default: dialog = null; } return dialog; } ``` DIAG_ABOUT is defined as `private static final int DIAG_ABOUT = 0;` The Log cat shows the following trace: ``` 03-04 11:37:08.760: ERROR/AndroidRuntime(726): Uncaught handler: thread main exiting due to uncaught exception 03-04 11:37:08.780: ERROR/AndroidRuntime(726): android.vie…

You need to use your `Activty` as the `Context` for the `Dialog` not the `Application`.

Android is looking for a view to display the Dialog in and the `Application` does not have one but your `Activity` will. The `Application` is an object which ties your app together and has a `Context` as it knows about which locale you're running in and so on, but it relies on Activities to display things to the user.

Replace:

```
dialog = new Dialog(getApplicationContext());
```

with:

```
dialog = new Dialog(this);
```
