我有一个使用android-ndk-r9c和当前android sdk构建的复杂应用程序，当启用checkjni时失败，因为它默认情况下在大多数现代的dalvik虚拟机（后冰淇淋三明治，即。 4.0.0）android设备。我的应用程序在模拟器上正常运行，如果运行“adb -e shell stop / adb -e shell setprop dalvik.vm.checkjni false / adb -e shell start”，但崩溃（checkJNI app bug）错误，作为JNI启动java代码使用的是本地（非“全局”）指针。
这个dalvik虚拟机架构发生了几年前的变化，并且在我发现的一些“JNI技巧”文件中有所提及，但是我试图用“GLSurfaceView_SDL.java”代码来全局化指针得分（呃）少。 （我不是c ++大师，甚至不是新手...）
我附上了两个文件。首先显示两个“adb logcat”片段，第一个应用程序启动并运行并退出ok，第二个，启用“checkjni”，并且它崩溃“dalvik”虚拟机，声称“陈旧的本地指针”。有人告诉我，我无法调整应用程序以禁用“checkJNI”引用检查。
所以，我停了下来。触发“陈旧本地指针”引用的代码在GLSurfaceView_SDL.java中，我附加了“class GLThread”的代码。
对于经验丰富的c ++专家来说，这可能不是一个难以解决的问题。我摆弄，使“mGL”处理公开，因为它在“mRenderer.onDrawFrame（mGL）;”哪里 我附加的logcat文件中指出了错误的本地引用。 （（logcat output :) GLSurfaceView_SDL $ GLThread.run（GLSurfaceView_SDL.java:946）。
我尝试使用java中的“NewGlobalRef”来制作全局指针是不成功的。 建议表示赞赏。 - 罗斯。
两个文件：1）模拟器的Logcat输出，显示app运行正常，第二个：“checkjni true”，并且dalvik VM崩溃。 2）“GLTHread”类的代码片段，来自“GLSurfaceView_SDL.java”JNI代码，用于设置渲染表面，并将控制传递给本机代码。
Output of "logcat", from 7-inch WSVGA Android Emulator, without checkJNI "feature" enabled.
[ App works *perfectly*, passes significant regression tests, & does no obvious harm... :) ]

--------------> I/dalvikvm( 2482): CheckJNI enabled: not enabling JNI app bug workarounds
-------- Any for app to enable "JNI app bug workarounds", that "dalvik"has turned off ???
