1. mv assets/models to phone's /sdcard/kantv/models manually before build, it will reduce the size of apk significantly

   zhouwg:$ cd cdeosplayer/kantv/src/main/assets/
   zhouwg:$ ls
   config.json  jfk.wav  kantv.bin  mnist-4.png  mnist-5.png  mnist-7.png  models  qnnlib  res  test.m3u
   zhouwg:$ du -h
   212M    ./models
   3.0M    ./res
   49M     ./qnnlib
   264M	.
   zhouwg:$
   
   

2. build APK from source code by command line(default is Release build)

   . build/envsetup.sh
   lunch 1
   ./build-all.sh android
