我已经设法（最终）使用Android Studio＆amp; amp;构建了一个测试SDL2应用程序。 NDK使用Gradle实验插件。
当我尝试运行项目时，它将无法运行。我收到以下错误：
:app:compileDebugSources

:app:transformClassesWithDexForDebug UP-TO-DATE
:app:processDebugJavaRes UP-TO-DATE

我的项目可以从here下载：
有人可以帮助我让它运行吗？
这是堆栈跟踪：

答案 0 :(得分：0)
我自己发现了这个问题。当SDL源通过命令行上的ndk-build构建为库时，该项目之前已包含libmain.so。 android.sources下有2个部分 - 一个叫做main.jni，另一个叫main.jniLibs。我删除了main.jniLibs，现在它开始执行了。
