Hi, Priya (cc [email protected]<mailto:[email protected]> for those who are also interesting in your issues)
Issue :With Cordova-Crosswalk(5.34.104.5) , we started getting screen flickering issues in Samsung Note 10.1. Then we investigated and found errors in logcat related to display : Gralloc:out of memory. Please find attached log "14Oct2014.txt' [hmin] Would the error message “invalid gralloc handle (at 0x0)” only happen after you launch your crosswalk app? You can verify this by 1) Run “adb logcat -c”;2) Re-launch your app and then see the adb logcat output. Regarding to the screen flickering, could you please describe the details? Does the screen firstly becomes white and shows the app in a very short time, or something else? I compiled my projects successfully, but when I run my app on device(Samsung Note 10.1) , I get an error "Unfortunately app has stopped". [hmin] It is a strange failure without any more information. Is the error showed in a popup dialog or output by adb logcat? If the Crosswalk is crashed, the adb logcat would output the Java exception or native information (e.g. register, call trace).

I would elaborate the problem here to give you a better insight into it: 1) Initially we had Cordova app and to boost up its performance we integrated it with crosswalk. Here Crosswalk version that we are using is: https://download.01.org/crosswalk/releases/crosswalk/android/stable/5.34.104.5/arm/ 2) Issue :With Cordova-Crosswalk(5.34.104.5) , we started getting screen flickering issues in Samsung Note 10.1. Then we investigated and found errors in logcat related to display : Gralloc:out of memory. Please find attached log "14Oct2014.txt'. Our app uses is doing extensive use of dynamic images which cannot be made static. 3) Yesterday , I was trying to upgrade crosswalk version. https://download.01.org/crosswalk/releases/crosswalk/android/stable/8.37.189.12/arm/ and I followed this link : https://github.com/crosswalk-project/crosswalk-cordova-android#requires and following steps: • Import Crosswalk-based Cordova Android and XWalkCoreLibrary library projects by File > Import... > Existing Android Code Into Workspace. Point to[path_to_cordova_xwalk_android]/framework and click Finish. • Build xwalk_core_library and Cordova projects. • Import generated project by File > Import... > Existing Android Code. Point to the generated app path. • Right click on the project root: Run as > Run Configurations • Click on the Target tab and select Manual (this way you can choose the emulator or device to build to) I compiled my projects successfully, but when I run my app on device(Samsung Note 10.1) , I get an error "Unfortunately app has stopped". There are nor errors logs so no clue that what went wrong. Any suggestion what could be wrong here? Answer to your questions here: 1. Is it the same as your usage scenario? Please correct me if I am wrong. Yes this is one of the scenarios that describes how we are using dynamic images in our app. 2. Do you have a try on other Android devices except Samsung Galaxy Note 10? Yes, we did on Samsung Tab2. Crosswalk did not have screen flicker issues on Tab2 but I am not sure about gralloc memory issue. I can test it on Tab2 and let you know regarding the same. Please let me know your suggestions regarding how to resolve this issue. Thanks for all your help Priya ---- On Tue, 14 Oct 2014 00:33:28 -0700 Min<[email protected]<mailto:[email protected]>> wrote ---- Hi, Thanks for using Crosswalk and reporting the issue to us. Before I dig into the issue your reported at https://crosswalk-project.org/jira/browse/XWALK-2730, I try to create a test case for reproducing it according to your descriptin.
