starting an LC Android app takes up to 15 seconds

[Matthias Rebbe | M-R-D]

Hi,

i have created an Android App which takes about 10 to 15 seconds to start. The user sees a black screen in the meantime.
Not the best user experience.

The app is about 2.5mb in size and uses a Datagrid and SpreadLib (XLSX import Library).

Tried it on a 10" tablet and also on 2 different Android Phones. 

What is causing this slow loading? 2.5MB app size should not be a problem with 4gb memory and 16gb flash memory, shouldn´t it?

Is there anything i can do to speed up the start?

Any ideas?

Regards,

Matthias
