Opening shared libraries directly from an APK

In API level 23 and above, it’s possible to open a .so file directly from your APK. Just use System.loadLibrary("foo") exactly as normal but set android:extractNativeLibs="false" in your AndroidManifest.xml. In older releases, the .so files were extracted from the APK file at install time. This meant that they took up space in your APK and again in your installation directory (and this was counted against you and reported to the user as space taken up by your app). Any .so file that you want to load directly from your APK must be page aligned (on a 4096-byte boundary) in the zip file and stored uncompressed. Current versions of the zipalign tool take care of alignment.

Note that in API level 23 and above dlopen(3) will open a library from any zip file, not just your APK. Just give dlopen(3) a path of the form "my_zip_file.zip!/libs/libstuff.so". As with APKs, the library must be page-aligned and stored uncompressed for this to work.
