Hello,
I know that some other people here are developing Android JNI apps.
For me it has worked perfectly so far, but as we just got a Galaxy S4
in the office I thought of testing my app there and boom =( It crashes
at the startup:

Any ideas?
I am not doing anything unusual, and exact same APK works fine in HTC
Wildfire, Xperia Mini, Galaxy Nexus, etc, etc.
=(
it runs JNI_onCreate to the end, so at least code is being executed.
The routine that it complains about is declared correctly:
procedure
Java_com_felipe_truedemocracy_TrueDemocracy_Translations_TranslateToISO639_2_Code(
env:PJNIEnv; this:jobject; AISOCode, ACountry: jstring); cdecl;
And is correct in the structure:
(name:'Translations_TranslateToISO639_2_Code';
signature:'(Ljava/lang/String;Ljava/lang/String;)V';
fnPtr:@Java_com_felipe_truedemocracy_TrueDemocracy_Translations_TranslateToISO639_2_Code;),
And is correct in RegisterNative:
// Register Pascal exported calls
if javaEnvRef^^.RegisterNatives(javaEnvRef, javaActivityClass,
@NativeMethods[0],length(NativeMethods))<0 then
begin
__android_log_write(ANDROID_LOG_FATAL, 'truedemocracy',
'javaEnvRef^.RegisterNatives failed');
end;
My only idea at the moment is to do the static export too... maybe
that will work, lets see.
