问题 I've made a jni library that dynamically loads plugins using dlopen, plugin library files have a different naming e.g. zzz_abc.so . eclipse and ant are correctly bundling these files in the apk, but the android packagemanager only unpacks files named libxxx.so , other filename patterns are ignored, perhaps in debug, gdbserver is added and unpacked on my 4.1 phone (but not on 4.4 genymotion emulator). There is something "magic" to control this behavior? 回答1: I've verified and unfortunately the

问题 Well, I'm on a project that uses rxtxSerial.dll (very buggy by the way). Anyway, I made a modification on the GUI to make it more user-friendly, initially the program shows up the main window and it's possible to open some other frames where the user can monitor certain devices designed by the company I work for. So when the user wanted to close the hole program and any windows where openend it showed up a dialog asking for the user close the oppened windows himself and then close the program

问题 I want to use universal windows in my project for windows 10 only. I need to compile all my UI&logic stuff to one exe-file (or dll). Like I could do the same with usual WPF application.

This native library depends on

问题 I am using a native library and having the exception below even though the method exists. I have a nativeInit function that is also exported to MapController and it works as expected. However, the nativeLoadScene method causes an error. JNI DETECTED ERROR IN APPLICATION: jmethodID was NULL in call to CallObjectMethodV from int com.demo.lib.MyController.nativeLoadScene(long, java.lang.String, java.lang.String[]) JNI methods JNIEXPORT jint JNICALL Java_com_demo_lib_MyController_nativeInit

问题 I have a JavaFX application that uses a preloader. What I'd like to do is package it up as a native bundle (Mac app or Windows exe file that contains a copy of the Java JDK) so users who don't have the right version of Java on their computers can still run the app. I've followed Oracles instructions for creating native bundles and for adding preloaders. What I get is exactly what you'd expect—a native bundle that runs my program. The problem is that the bundle completely ignores my preloader.
