Phonegap在Android上使用Crosswalk crashing构建应用程序

Question

我的应用是用Phonegap构建的，并使用了Crosswalk插件，在Android上使用了一小段时间后就崩溃了。我完全不知道为什么在不断的Googling和调试尝试之后会发生这种情况。任何帮助都是非常感谢的。

我在崩溃之前和之后的logcat输出：

任何人都可以提供的任何见解或帮助都是很棒的。

Answer 1

堆栈跟踪为：

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源代码中缺少JNI规范，并随后导致Error loading extension和Failed to initialize extension错误--要么意味着它可能在其他地方读取Failed to load native library (正如错误所述，可能是根本原因)。

确保a)本机程序集与System.loadLibrary()一起加载，以及b) JNI本机接口函数已定义。

@请参阅Android JNI Tips或Crosswalk's Jira。

我建议您删除android平台，然后再添加。然后重新构建。这在一段时间前对我有帮助。
