TTS gets killed when device rotated

unba1300 · Feb 15, 2012

Hi,
I'm using the TTS library to speak a large amount of text within an edittext. But when the device is rotated, the process stops. Is there some way to save its position in Pause and continue from there in Resume? Maybe using a combination of text.length, a percentage, and SelectionStart?

TTS should not be affected from the screen orientation change. You should declare it in Sub Process_Globals and only initialize it when FirstTime is True.

I had this in Activity_Resume...

B4X:

If TTS1.IsInitialized = False Then
  TTS1.Initialize("TTS1") 
End If

And this in Activity_Pause...

B4X:

TTS1.Release

As per the TTS tutorial. So I commented out TTS1.Release and now speech continues. But what will be the negative of not using TTS1.Release? Thanks.

The negative effect is that the speech will continue even when the user navigates to another program.

Another option is to call release only when UserClosed = True. This way the object will only be released when the user presses on the back key.

Thanks Erel. That works for me.
