Java Question assets and libs folders

[warwound]

If a native Android library requires resources in the assets and libs folders and i copy these folders to my B4A project's Objects folder and mark them read-only will they be compiled into the B4A application in the same way tha we add drawables etc?

I have an excpetion:

java.io.FileNotFoundException: droyd/sdk.properties

In my Objects folder i have assets/droyd/sdk.properties and it's marked read only.

I also have folders:

assets/droyd/resources/svg/
assets/droyd/resources/svg/poi

These both contain a number of SVG graphics.

Then there is:

assets/droyd/themes

And:

libs/armeabi
libs/armeabi-v7a
libs/x86

These folders contain JNI .so files.

Will the B4A compiler include all of these additional folders?

Does the B4A compiler handle JNI files correctly?

This is the log output i'm trying to debug:

Any file that you put under the Files folder will be copied to the assets read-only folder.

The compiler doesn't do anything with JNI files. You should manually copy them to File.DirInternal and then load them with:

System.load(File.Combine(File.getDirInternal(), "libstlport_shared.so"));
