I suppose you are talking about native code and LCL-CustomDrawn in Android, correct?
The source code for DebugLn in Android is located in lcl/interfaces/customdrawn/customdrawnobject_android.inc procedure TCDWidgetSet.AndroidDebugLn(ASender: TObject; AStr: string; var AHandled: Boolean; Target: TLazLoggerWriteTarget; Data: Pointer); begin AHandled := Target in [lwtStdOut, lwtStdErr]; if not AHandled then exit; __android_log_write(ANDROID_LOG_INFO, 'lclapp', PChar(AccumulatedStr+AStr)); AccumulatedStr := ''; end; So I suppose that FPC threading breaks __android_log_write. Try using __android_log_write directly instead of DebugLn to be 100% sure. Notice that __android_log_write is a NDK function, it is part of the Android NDK released by Google, it is not our code. Try asking in the android-ndk Google Groups about the problem. Google engineers there helped me with problems. One idea would be to try to see if creating a thread using pthreads directly would also break __android_log_write... I never created a thread this way, so I have no idea how to do it, but Google shows many pthreads tutorials. I suppose that Android uses pthreads, but could be wrong. -- Felipe Monteiro de Carvalho -- _______________________________________________ Lazarus mailing list [email protected] http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
