blackberry
I have an app that is listening in background and when the user clicks "send" it displays a dialogue. However I need to bring my app to foreground so the user answers some questions before letting the message go. but I haven't been able to do this, this is the code in my SendListener:
SendListener sl = new SendListener(){
public boolean sendMessage(Message msg){
Dialog myDialog = new Dialog(Dialog.D_OK,
"message from within SendListener",
Dialog.OK,Bitmap.getPredefinedBitmap(Bitmap.EXCLAMATION),
Dialog.GLOBAL_STATUS)
{
//Override inHolster to prevent the Dialog from being dismissed
//when a user holsters their BlackBerry. This can
//cause a deadlock situation as the Messages
//application tries to save a draft of the message
//while the SendListener is waiting for the user to
//dismiss the Dialog.
public void inHolster()
{
}
};
//Obtain the application triggering the SendListener.
Application currentApp = Application.getApplication();
//Detect if the application is a UiApplication (has a GUI).
if( currentApp instanceof UiApplication )
{
//The sendMessage method is being triggered from
//within a UiApplication.
//Display the dialog using is show method.
myDialog.show();
App.requestForeground();
}
else
{
//The sendMessage method is being triggered from
// within an application (background application).
Ui.getUiEngine().pushGlobalScreen( myDialog, 1,
UiEngine.GLOBAL_MODAL );
}
return true;
}
};
store.addSendListener(sl);
App is an object I created above:
Application App = Application.getApplication();
I have also tried to invoke the App to foreground using its processID but so far no luck.
