Now I used dexdump on /data/app/com.my.internal.apk and saw
SystemProperties class is in the classes.dex file:
Class #9 -
Class descriptor : 'Lcom/sprint/internal/SystemProperties;'
Access flags : 0x30001 (PUBLIC VERIFIED OPTIMIZED)
Superclass : 'Ljava/lang/Object;'
Can someone tell me why DexClassLoader.loadClass can not find it?
Thanks.
