call so files in android

1 can be dynamically loaded so files (ie, so the file is not placed in the lib directory, but sd inside), and if so, how call a function? This document is designed for android so compiled.

2 If the above functions can not be achieved, can be initialization function in the program, so that android system itself so file to load, and then call

Under 3 documents for a dynamic call so that the file is not packaged so in the case of the program, have it any other solution?

Please elaborate or give a link, thank you, not a long time to learn android, ndk is not used.

Can Be initialization function in the program

What does it mean

Try:
System.loadlibrary ("/ mnt / sdcard / folder / name.so")
Or
System.loadlibrary ("/ mnt / sdcard / folder / libname.so")
If not, you can tell JVM path so where, PathClassLoader loads so from two locations, one path is fixed, it may be:
lib / / lib . so, another path in the system properties defined, its key is java.library.path

Can not load library,
directly from the sdcardYou can be copied to / data / data / package name / files / below, and then load the library,
Then you can jni layer load, you can. Loadlibrary only need the library name, load function is the absolute path in java layer.
