问题 I have already read some relevant answers on stackoverflow,but seems no one has answered my question.I will get the android ID from native code,i.e. calling the method getAndroidIDfromNativeCode in C code,(so the JVM is inited in the native code by method create_vm),you know that when calling the method getContentResolver ,you must use a Android Context instance to call it,so how to get this Context instance ? static jstring native_code_getAndroidID(JNIEnv *env, jobject thiz) { jclass c

问题 In other VS 2015 C# project types the Property Page for the project contains a checkbox under the Debug tab which enables native debugging. I cannot see this in an Asp.Net Core project and am therefore unable to step into a C++ Dll dependency which I have the code for. 回答1: It would have a limitation for native debugging directly. Reference: No native code debugging in CoreCLR console application projects in VS2015? One workaround is that using the "Attach to process". 来源： https:/

问题 This question already has answers here : Is is possible to export functions from a C# DLL like in VS C++? (4 answers) Closed 3 years ago . I have a .net assembly written in C#, and I'm looking to export a native C function from the assembly. I have an application which will perform a 'LoadLibrary()' on any DLL's found in a 'plugin' folder. After loading the DLL, the application performs a 'GetProcAddress' looking for a function named 'Register'. The application expects this function to follow

问题 What is the best way, if even possible, to see the underlying code for the predefined functions in Javascript. Is there documentation that shows how these were coded, or an easy way to actually view the underlying code? parseInt parseFloat isNaN 回答1: They are native functions, and maybe coded in the language your JS engine was written in - you'd need to contact it's source. However, you probably are more interested in the EcmaScript specification that describes how the algorithms work. And if

问题 I have to use a native library (this is not my decision). The library already has a JNI wrapper, and the example Android NDK code works. But the library initialization routines return native handles and the developer is required to correctly close them . Now, there's an interesting question: where to call the close_handle routines from? At least in theory, each incorrect termination may result in temporary files left somewhere on the disk or some other kind of resource leak. Library
