/**

* Bug on Android >= 4.2. Fixed in 4.2.2 ?

|
|
* http://code.google.com/p/android/issues/detail?id=41901
|
|
*
|
|
* DialogFragment disappears on pressing home and coming back. This also happens especially in
|
|
* FileDialogFragment after launching a file manager and coming back.
|
|
*
|
|
* Usage: <code>
|
|
* DialogFragmentWorkaround.INTERFACE.runnableRunDelayed(new Runnable() {
|
|
* public void run() {
|
|
* // show dialog...
|
|
* }
|
|
* });
|
