我在wordpress中使用API来获取我拥有的标题数量.我的代码适用于除5.x之外的所有
Android版本.当我在我的应用程序中推送一个帖子时,很遗憾地关闭了.我不知道Android 5版本有什么问题.有谁知道解决方案是什么？
这是我的logcat：

解决方法
Android 5.0使用不同的虚拟机(以前是Dalvik,现在是ART).这个新VM对JNI代码要严格得多.
现在进行的检查之一是不允许您在异常中调用本机代码.
您可以在 http://developer.android.com/training/articles/perf-jni.html#exceptions找到更多详细信息. 如果您不是本机库的作者,则作者需要更正它.同时,您可以通过避免Java的异常来避免对本机调用的调用,但如果异常发生在您不拥有的库中,则可能无法实现…
