Phonegap使用Crosswalk在Android上崩溃构建应用程序

Question

My app built with Phonegap Build and using the Crosswalk plugin is crashing after a little bit of use on Android. I have absolutely no idea why this is happening after constant Googling and debugging attempts. Any help is appreciated.

My logcat output right before and after the crash:

Any insight or help that anyone can provide would be great.

Answer 1

the stacktrace reads:

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

this either means, that the JNI Specification within the Java source is absent and subsequently leads to the Error loading extension and Failed to initialize extension errors - or it might read Failed to load native library elsewhere (probably the root cause, as the error tells).

make sure that a) native assembly gets loaded with System.loadLibrary() and b) that the JNI native interface functions have been defined.

@see Android JNI Tips or Crosswalk's Jira .

i sugest you remove the android platform then add again. Then build again. This helped me a while ago.
