[SOLVED][Android] call external library with a string type in parameter ?

[ROCABDEL]

I just did the test on the bass library, but I could not go too far ..
I happen to load the dll and initialize it, the problem is how to call a function with a "string" type..

ex:

in Bass.pas i:
 

Code: [Select]

BASS_StreamCreateFile      : function(mem: BOOL; f: Pointer; offset, length: QWORD; flags : DWORD): HSTREAM;
and in BASS.java i:
 

Code: [Select]

public static native int BASS_StreamCreateFile(String file, long offset, long length, int flags);
I called in the first BASS_StreamCreateFile with PChar(F) but the second I do not know how to call it.

Sorry for my English 
thx

You can access Java APIs using JNI, I just added an example here:

http://wiki.freepascal.org/Android_Programming#Example_1:_Creating_a_Java_object_and_calling_a_Java_method

Try to use it as an example and build your own JNI code. If you have trouble then post here your partial JNI code and I will help you fix it and make it work.

Yours is a bit different from my example, so I created a pseudo-code which might work explaining how to call static methods here:
