Weird Native Crash – pid: 0, tid: 0 signal 11 (SIGSEGV), code 1 (SEGV_MAPERR)
Assuming your native code is enum shape_type_e { stUNHANDLED = 0, //!< Unhandled shape data. stPOINT = 1 //!< Point data. … }; and your managed code is public enum class ShapeType { Unhandled = 0, Point = 1, … }; You can cast from the native to the managed using shape_type_e nativeST = stPOINT; … Read more
Answer quoted by lubos hasko is good but it doesn’t work for 64-bit assemblies. Here’s a corrected version (inspired by http://apichange.codeplex.com/SourceControl/changeset/view/76c98b8c7311#ApiChange.Api/src/Introspection/CorFlagsReader.cs) public static bool IsManagedAssembly(string fileName) { using (Stream fileStream = new FileStream(fileName, FileMode.Open, FileAccess.Read)) using (BinaryReader binaryReader = new BinaryReader(fileStream)) { if (fileStream.Length < 64) { return false; } //PE Header starts @ 0x3C … Read more
The answer lies in a new Android security feature: Package Visibility. This works similar to iOS’ LSApplicationQueriesSchemes. Targeting Android 11 (SDK 30) requires you to update your AndroidManifest.xml and include a list of applications you’re querying for.

that a Surface is being used hints for OpenGL ES and GLSurfaceView – which extends View. a possible workaround might be to disable hardware acceleration for the views, which cause it to crash on Android 8.1 and 9.0 (as libhwui.so hints for) – because even if it gets fixed, any device not updated will still … Read more
c++/cli can theoretically be used with WPF/Silverlight using the trick of replacing the C# generated from the XAML with a macro definition that can be used inside the main class in a code behind file. I worked out this technique but haven’t had the motivation to take it beyond theory – I’m quite happy mixing … Read more
explanation the sample code shows how to store 2 different bitmaps (small ones, but it’s just a demo), recycle the original java ones, and later restore them to java instances and use them. as you might guess, the layout has 2 imageViews. i didn’t include it in the code since it’s quite obvious. do remember … Read more
