Hi, I'm planning to migrate our android app from android webview to XWalkView for UI performance issue, and I had got some problems:
1. I made a test apk following the guidance, it's worked with latest 'stable' and 'beta' versions, but got runtime exception when I tried to use the latest canary build such as crosswalk-webview-10.39.228.0-arm.zip. The log is at the end of this mail. 2. If I want to build crosswalk-webview like crosswalk-webview-10.39.228.0-arm.zip from the source code, how to? I did not find the direct target in build.ninja. We need some customization on it. 3. Does it possiable to make the backgroud of XWalkView transparent? I found a previous discuss mail about this ( https://lists.crosswalk-project.org/pipermail/crosswalk-help/2014-October/000474.html), and the bug 'XWALK-1910 <https://crosswalk-project.org/jira/browse/XWALK-1910>'. This feature is very important to us, would anybody tell us if it is possiable, and how difficult it is if we develop from xwalk source code? Thanks a lot! -------------------------Exception Log----------------------- 10-23 17:26:06.438 I/ActivityManager( 1454): Start proc com.targetv.kavawebtest for activity com.targetv.kavawebtest/.WebTestActivity: pid=29069 uid=10049 gids={50049, 1006, 3003, 1015, 1028} 10-23 17:26:06.448 D/Console ( 1673): App Paused 10-23 17:26:06.548 E/Trace (29069): error opening trace file: No such file or directory (2) 10-23 17:26:06.588 D/TEST (29069): intentToResolve size is:0 10-23 17:26:06.698 D/AndroidRuntime(29069): Shutting down VM 10-23 17:26:06.698 W/dalvikvm(29069): threadid=1: thread exiting with uncaught exception (group=0x412e1930) 10-23 17:26:06.718 E/AndroidRuntime(29069): FATAL EXCEPTION: main 10-23 17:26:06.718 E/AndroidRuntime(29069): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.targetv.kavawebtest/com.targetv.kavawebtest.WebTestActivity}: android.view.InflateException: Binary XML file line #1: Error inflating class org.xwalk.core.XWalkView 10-23 17:26:06.718 E/AndroidRuntime(29069): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2181) 10-23 17:26:06.718 E/AndroidRuntime(29069): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2231) 10-23 17:26:06.718 E/AndroidRuntime(29069): at android.app.ActivityThread.access$600(ActivityThread.java:142) 10-23 17:26:06.718 E/AndroidRuntime(29069): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1235) 10-23 17:26:06.718 E/AndroidRuntime(29069): at android.os.Handler.dispatchMessage(Handler.java:99) 10-23 17:26:06.718 E/AndroidRuntime(29069): at android.os.Looper.loop(Looper.java:137) 10-23 17:26:06.718 E/AndroidRuntime(29069): at android.app.ActivityThread.main(ActivityThread.java:5059) 10-23 17:26:06.718 E/AndroidRuntime(29069): at java.lang.reflect.Method.invokeNative(Native Method) 10-23 17:26:06.718 E/AndroidRuntime(29069): at java.lang.reflect.Method.invoke(Method.java:511) 10-23 17:26:06.718 E/AndroidRuntime(29069): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:936) 10-23 17:26:06.718 E/AndroidRuntime(29069): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:703) 10-23 17:26:06.718 E/AndroidRuntime(29069): at dalvik.system.NativeStart.main(Native Method) 10-23 17:26:06.718 E/AndroidRuntime(29069): Caused by: android.view.InflateException: Binary XML file line #1: Error inflating class org.xwalk.core.XWalkView 10-23 17:26:06.718 E/AndroidRuntime(29069): at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:698) 10-23 17:26:06.718 E/AndroidRuntime(29069): at android.view.LayoutInflater.inflate(LayoutInflater.java:466) 10-23 17:26:06.718 E/AndroidRuntime(29069): at android.view.LayoutInflater.inflate(LayoutInflater.java:396) 10-23 17:26:06.718 E/AndroidRuntime(29069): at android.view.LayoutInflater.inflate(LayoutInflater.java:352) 10-23 17:26:06.718 E/AndroidRuntime(29069): at com.android.internal.policy.impl.PhoneWindow.setContentView(PhoneWindow.java:270) 10-23 17:26:06.718 E/AndroidRuntime(29069): at android.app.Activity.setContentView(Activity.java:1962) 10-23 17:26:06.718 E/AndroidRuntime(29069): at com.targetv.kavawebtest.WebTestActivity.onCreate(WebTestActivity.java:34) 10-23 17:26:06.718 E/AndroidRuntime(29069): at android.app.Activity.performCreate(Activity.java:5240) 10-23 17:26:06.718 E/AndroidRuntime(29069): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1080) 10-23 17:26:06.718 E/AndroidRuntime(29069): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2145) 10-23 17:26:06.718 E/AndroidRuntime(29069): ... 11 more 10-23 17:26:06.718 E/AndroidRuntime(29069): Caused by: java.lang.ClassNotFoundException: Didn't find class "org.xwalk.core.XWalkView" on path: /data/app/com.targetv.kavawebtest-2.apk 10-23 17:26:06.718 E/AndroidRuntime(29069): at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:65) 10-23 17:26:06.718 E/AndroidRuntime(29069): at java.lang.ClassLoader.loadClass(ClassLoader.java:501) 10-23 17:26:06.718 E/AndroidRuntime(29069): at java.lang.ClassLoader.loadClass(ClassLoader.java:461) 10-23 17:26:06.718 E/AndroidRuntime(29069): at android.view.LayoutInflater.createView(LayoutInflater.java:552) 10-23 17:26:06.718 E/AndroidRuntime(29069): at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:687) 10-23 17:26:06.718 E/AndroidRuntime(29069): ... 20 more 10-23 17:26:06.728 W/ActivityManager( 1454): Force finishing activity com.targetv.kavawebtest/.WebTestActivity 10-23 17:26:06.888 D/dalvikvm( 1454): GC_FOR_ALLOC freed 736K, 19% free 8056K/9900K, paused 76ms, total 78ms 10-23 17:26:06.888 I/Process (29069): Sending signal.
