Q:

Solution for install big application on Android

I have TTS application with a huge raw resource (a lot of wav file for unit selection)
maybe more than 1 gb.  So  how can i install it 
Somebody said that i have to put all raw resource in SD card, and the rest on internal memory, so how can i do that  
Any help is appreciated

1, The best solution.  APK Expansion Files
2, Download the files you needs.  when your app startup.
