Comment by Julian Dropmann (Inactive) [ 08/Aug/16 ]
Cao Can I think I figured it out, It seems that you cannot reproduce the issue because you set the preferences and
XWalkView in onXWalkReady instead of in onCreate.
If you do it as the docs describe (or without XWalkActivity even), you will be able to reproduce the crash: https:
project.org/apis/embeddingapidocs_v6/org/xwalk/core/XWalkActivity.html
It does not seem to be generally applicable though because in our production app, I get the error even when I wa
onXWalkReady (using XWalkActivityDelegate).

Zhang Xiaofeng,I cannot reproduce this issue with crosswalk 20.50.533.12 and crosswalk 23.52.568.0.

Julian Dropmann we can't reproduce this issue using your sample code on Android N device (nexus9)
Comment by Valentin Krasznai (Inactive) [ 13/Sep/16 ]
Zhang Xiaofeng, I have exactly the same issue on a Nexus 5X with Android 7.0. I run the same code that Julian
attached, just with 21.51.546.6. I used Android Studio to build an apk, then installed it to the phone.
Comment by Zhang Xiaofeng [ 13/Sep/16 ]
Valentin Krasznai could you just use https://crosswalk-project.org/jira/secure/attachment/15636/MainActivity.ja
new Android Studio project to try? if the issue still happens, please provide more details on how to reproduce it.

Zhang Xiaofeng
Sorry but I do not see any variable which is not already present here:
Given you use the same hardware, same system image and same app source code, there are not much details to p
Also the exception/stack trace is so specific, that just by analyzing the source you should be able to find the setB
call in initTextureView, which according to the exception is not supported for TextureView.
So honestly what information are you looking for? Its everything present here.
I btw. volunteer to test your fix, because I can reproduce this with no issues at all.

I tried with your MainActivity.java, and the issue still happens. This line is the cause: mXWalkView = new XWal

These two lines seems interesting:

They are from Chromium 51 according to my Android Studio, but the android.view.TextureView is from Androi
and maybe these classes are not compatible.
UPDATE
You should just remove/ignore this.mTextureView.setBackgroundColor(-1); from
org.chromium.content.browser.ContentViewRenderView, when the Android build version is greater than or equ
Comment by Zhang Xiaofeng [ 17/Sep/16 ]
Valentin Krasznai I know why I can't reproduce the issue. That's because you use Android SDK 24 to build and
targetSdkVersion is 23.
However, ContentViewRenderView.java is Chromium upstream code, so we can't change it. Can targetSdkVers
request currently?
Comment by Valentin Krasznai (Inactive) [ 20/Sep/16 ]
Yes, it can work for me as a temporary solution, thanks! But I want to update the targetSdkVersion to 24 as soon
do you know which Crosswalk will support the targetSdkVersion 24?
Comment by Zhang Xiaofeng [ 20/Sep/16 ]
Sorry, it depends on when Chromium build targetSdkVersion will be upgrade to 24..
Comment by Valentin Krasznai (Inactive) [ 22/Sep/16 ]
I see, thank you!
Comment by Hua Hou [ 16/Mar/17 ]
Zhang Xiaofeng: Looks like that Chromium has bumped targetSdkVersion to 24:
https://codereview.chromium.org/2570283002
Is there an XWalk beta version which uses the latest Chromium?
I am still getting the "TextureView doesn't support displaying a background drawable" error when using the late
version 23.53.589.4
Thanks.
Comment by Zhang Xiaofeng [ 16/Mar/17 ]
sorry, Crosswalk project had already been stopped. please see the attached.

Sorry to hear that and thank you for the update.
