Hello,

I need to convert this:

android]$ gedit
~/Programas/android-ndk-r5/platforms/android-8/arch-arm/usr/include/jni.h

void        (*CallStaticVoidMethodV)(JNIEnv*, jclass, jmethodID, va_list);

To Pascal. I tryed using array of const, but it keeps crashing in this call =(

CallStaticVoidMethodV:procedure(Env:PJNIEnv;AClass:JClass;MethodID:JMethodID;Args:array of const);{$ifdef mswindows}stdcall;{$else}cdecl;{$endif}

Any ideas if using array of const is a good idea or if something else is better? My target is Android (via arm-linux in FPC)

thanks,

Does this work?
CallStaticVoicMethodV:
procedure(Env:PJNIEnv;AClass:JClass;MethodID:JMethodID); {$ifdef mswindows}stdcall;{$else}cdecl;{$endif} varargs;

I recon that it is almost the same, according to the FPC documentation

"array of const" or "varargs" only matches "..." in C. va_list is an ABI-defined, and often at least partially handled via compiler magic, record type. Look for the copy of varargs.h for the gcc version you use on Android.

Hello,

Thanks, it is good to have some input as to what would be necessary, but in the mean time I solved my problem in another way. JNI has another way of sending the parameters, the A functions:

CallStaticVoidMethodA:procedure(Env:PJNIEnv;AClass:JClass;MethodID:JMethodID;Args:PJValue);

And this worked for me sending a pointer to the first element of a pascal static Array in the parameter Args.
