Parse Error

I completed the TalktoMe app and successfully downloaded the .apk to a Nexus 7 tablet after changing the Security settings to allow non Play Store apps.

I tried to do the same thing on another Nexus 7 tablet and received a Parse Error There was a problem parsing the package message.

The successful download tablet is running KitKat and running off the hidden district network. The problem tablet is running lollipop off a different school wireless network.

Any ideas on what I need to do?

Does the lollipop device have TTS Extended Service?

In order for this component to work, the device must have the TTS Extended Service app by Eyes-Free Project installed. You can download this from http://code.google.com/p/eyes-free/downloads/list        

Another possibility is that the device is out of memory...perhaps the devices has very many apps loaded and it is using up all the memory and there is insufficient memory to allow the  TalktoMe app to load.

Make sure TTS is available, then see what the memory usage is using the Android Settings (on the device) to see if memory is at or very near maximum capacity.
