问题 I have a very strange bug on Android that I can't explain. Most of the time, my app (made in Delphi with FireMonkey) ends with External exception xx or Access violation at address xxx, accessing address 0000000x and I can't explain why. The exceptions appear in different places of my software, and at very unexpected times. For example, the last error log I receive just now is this one: libapp.so $0000007D91A61548 Grijjy.Errorreporting.TgoExceptionReporter.GlobalGetExceptionStackInfo

I'm planning to include native code within the plugin. Thanks in advance! 来源

One is like: public PathClassLoader(String dexPath, ClassLoader parent) { super(dexPath, null, null, parent); } and the other is like: public PathClassLoader(String dexPath, String libraryPath, ClassLoader parent) { super(dexPath, null, libraryPath, parent); } But I cannot find the call of the second constructor in the source

阅读更多关于 How do I add an Andrioid NDK-built shared library to my APK without using NDK?

问题 Pretty much exact duplicate of Add a native lib to an APK. Since there was no answer I decided to ask again. I have an Android project. I have an .so library built with android NDK. And I want to use this .so in my project, preferrably - without using NDK. So, how do I tell Eclipse (or Android tools) that I need certain .so to be built into my APK? 回答1: It's actually easier than I expected. All I had to do is place the .so in libs/armeabi-v7a - Eclipse saw it and integrated into APK. However,
