android - 使用 Crosswalk 在 Android 上崩溃的 Phonegap 构建应用程序

Question

我使用 Phonegap Build 构建并使用 Crosswalk 插件的应用程序在 Android 上使用了一段时间后崩溃了。我完全不知道为什么在不断的谷歌搜索和调试尝试后会发生这种情况。感谢您的帮助。

崩溃前后我的 logcat 输出:

堆栈跟踪显示:

D/dalvikvm(26498): No JNI_OnLoad found in /data/app-lib/com.foo.bar-1/libxwalkdummy.so 0x42865d60, skipping init

这要么意味着 Java 源代码中的 JNI 规范不存在并随后导致 Error loading extension 和 Failed to initialize extension 错误 - 或者它可能读取无法在其他地方加载 native 库(可能是根本原因，如错误所示)。

确保 a) native 程序集加载了 System.loadLibrary() b) JNI已定义 native 接口(interface)函数。
