I have a strange problem, I pass data from the android String via JNI. pass
data from FreePascal wideString successfully using the following code
NewString: function (Env: PJNIEnv; const Unicode: PJChar; Len: JSize):
JString; cdecl;
GetStringChars:function(Env:PJNIEnv;Str:JString;IsCopy:PJBoolean
PJChar is defined as a pointer to a word. Casting to WideString isn't
working since internally Widestring has extra bytes for reference count and
string length. These extra bytes are locate before the actual string. This
explains why assigning Pointer(WStr) to PJChar works.
Try
Result := WideStrin
thanks for the response.
I am doing what you suggest. but it's still the same.
I debug this line of code using android log
Chars := Env^.GetStringChars(Env, AJString, nil);
__android_log_write(ANDROID_LOG_DEBUG,'proj_debug',PChar(Chars));
and the log I retrieved :
04-26 17:53:17.942: DEBUG/pr

Pchar(Chars) interpretes your widechars as chars. The widechar e is
converted to the chars e and #0. The #0 is end of line for a pchar. So your
debug output is as expected.
Take a look at

2c45. It talks about the same pr
Yes, there's bug. thanks you.
I using GetStringUTFChars
function JNI_JStringToString(Env: PJNIEnv; JStr: jstring): String;
var
IsCopy: Pjboolean;
Chars: PChar;
begin
if JStr = nil then
begin
Result := '';
Exit;
end;
Chars:= Env^.GetStringUTFChars(Env, JStr, IsCopy);
if Char
