How to unload a native library?

[wavelet]

Hi all,
I use the below snippet to load a native shared library
static {
System.loadLibrary("mylib_name");
}


How I can unload the lib manually.

thanks.

wavelet,

You just delete it from system/lib

There’s a bit of a difference between unloading and uninstalling, Octaviano. :-)

 

There is no Java-approved way to unload a native library (there is no System.unloadLibrary() call.) This is part of the reason Java has so often downplayed JNI in general. You might be able to write a JNI call to do a dlunload() (or whatever its equivalent on Dalvik/Android is), but that would itself require another native library.

Yes, there is no way to unload the library from Java. You can still call "dlclose()" from native code if you need this though.

(Of course, you may not be able to call dlclose() from the shared library you are unloading without crashing).
