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 http://groups.google.com/group/android-ndk/browse_thread/thread/e0ab7aefb398 2c45. It talks about the same problem calling GetStringChars from C. The function returns non null terminated utf16 data. You could also go the hard way, something along the lines of: Chars := Env^.GetStringChars(Env, JStr, @IsCopy); if (Chars = nil) then begin Result := '' end else begin len:=Env^.GetStringLength(Env, JStr); setlength(Result,len); move(Chars,Result[1],len*2); Env^.ReleaseStringChars(Env, JStr, Chars); end; -----Message d'origine----- De : fpc-pascal-boun...@lists.freepascal.org [mailto:fpc-pascal-boun...@lists.freepascal.org] De la part de herux Envoyé : mardi 26 avril 2011 13:06 À : fpc-pascal@lists.freepascal.org Objet : Re: RE : [fpc-pascal] android JNI JString to String 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/proj_debug(711): e <--- only "e" character from input AJString = eNp9zt0KwjAMBeBXCecBrApeCEmG+iRzdrX+dKMrMn16Y0G8M5Cr75ATbub7jR4+T3FIgtViiUa5 VS5xGPsfrA2c8lG5o5NghrJX7ikInqCzYCo5pgCKgq3NJ1x1+KuvqjEVH3yuXGuc3b4oX2knAO2t fgM6fNHEdbb2jGv1DUfmNOA= so I thought, this is not about that. but I do not know why ----- - -- View this message in context: http://free-pascal-general.1045716.n5.nabble.com/android-JNI-JString-to-Stri ng-tp4340388p4340649.html Sent from the Free Pascal - General mailing list archive at Nabble.com. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
