Hi Wanming Thank you for your response.
In the meantime we were able to find the problem. ProGuard emitted warnings regarding classes from Android. As soon as we disabled these warnings, as was also done in Chromium [1], the build worked again. [1] https://chromium.googlesource.com/chromium/src/+/b5c3f8a04315769ad6253f2f4cebcaa250ab3ef0%5E!/#F0 The rules we added to the ProGuard definition are as follows: -dontwarn android.view.* -dontwarn android.webkit.* -dontwarn android.app.assist.* Cheers > On 27 Nov 2015, at 10:08, Lin, Wanming <[email protected]> wrote: > > Hi, Troxler > > Thank you for trying Crosswalk! > > But I cannot reproduce this issue with below steps: > 1. $ cordova create foo (cordova CLI = 5.4.0) > 2. $ cd foo & cordova platform add android > 3. $ cordova plugin add cordova-plugin-crosswalk-webview (1.4.0 version with > Crosswalk 15+) > 4. $ cordova build android --release > > No error occurs, and two apks have been generated. > android-armv7-release-unsigned.apk > android-x86-release-unsigned.apk > > And I also sign one of them with below steps: > 1. $ keytool -genkey -v -keystore foo.keystore -alias foo -keyalg RSA > -keysize 2048 -validity 10000 > 2. $ jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore > foo.keystore android-x86-release-unsigned.apk foo > 3. $ zipalign -v 4 android-x86-release-unsigned.apk.apk foo.apk > > foo.apk can install & launch successfully. > > What is your cordova CLI version?
