3.16 and 3.17 crashes in libwebviewchromium.so

vkreal2 · July 13, 2018, 12:30am

We are seeing tons of these crashes in Play Console in 3.16 and also 3.17. We don’t have anything that uses the webview. Not sure why it would crash here

Any ideas anyone?

I am still using cocos v3.12 and I also had a lot of same crashes. 99% of them were on android 4.… The only solution I found was to disable hardware acceleration for android 4.. After adding this “fix” I see no crashes.

vkreal2 · July 14, 2018, 4:56am

@kds GREAT!

Did you disable hardware acceleration on the application or activity level?
https://developer.android.com/guide/topics/graphics/hardware-accel

I am thinking turning hardware acceleration off at activity level and toggle that on/off base on android 4 or not.
What you think?

<application android:hardwareAccelerated="true">
    <activity ... />
    <activity android:hardwareAccelerated="false" />
</application>

getWindow().setFlags(
    WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED,
    WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED);

kds · July 14, 2018, 6:55am

I am using admob and this is the only place where webview is used in my games. So, I disable hardware acceleration only for “com.google.android.gms.ads.AdActivity”. I am doing it in manifest through resources.

vkreal2 · July 14, 2018, 7:14am

@kds Thank you!

kds · July 16, 2018, 6:55am

No problem, let me know if it helped.

vkreal2 · July 16, 2018, 7:22am

@kds Thanks, I will!

For others here’s what we did https://stackoverflow.com/questions/13850259/is-there-a-way-to-disable-hardware-acceleration-only-for-android-4-0-3

wow4201 · July 20, 2018, 5:48am

Which version of play-services-ads are you using? I’m experiencing this with 11.8

vkreal2 · July 20, 2018, 6:08am

We haven’t deploy the fix yet so not sure if it work or not. I will get back when this happen.

As for play-services-ads it’s the current version that comes with SdkBox.

wow4201 · July 20, 2018, 9:50pm

I’m finding it impossible to specifically turn hardware accelerated rendering off for com.google.android.gms.ads.AdActivity using Android Manifest. At best, I can turn it off for the entire application, but even then Interstitial Ads still uses Accelerated Rendering.

I tested this, by Developer Options (hidden android menu) -> Show GPU View updates.
This will flick the screen where the GPU renders.

I’m just disabling admob for 4.4 and seeing if the issues persists. Then I’ll try Google Play Game Services.

vkreal2 · July 25, 2018, 1:23am

@wow4201 did any solution work for you?

wow4201 · July 25, 2018, 5:10am

I disabled admob from rendering on API 19 (4.4 kitkat) the issue resolved (100% confirmed) 50k installs. I’m trying to understand why this happens, probably memory leak related.
So this issue in particular in my case is caused by admob. Which kind of sucks cause that’s 14%+ less revenue. I’m not sure if it’s Banner or Inter or both.

vkreal2 · July 25, 2018, 5:28am

@wow4201 first of all that’s AWESOME you found a fix and sucks in revenue man! You mind sharing how you disabled admob for API 19? I tested the other fix and doesn’t seem to work for us.

Thanks!

wow4201 · July 25, 2018, 5:56am

I don’t code with cocos2d I use react-native. I just insert logic in my code to prevent rendering or triggering admob inter. Good luck! I just found this forum by searching this crash

kds · July 26, 2018, 4:44pm

@vkreal2 Hmm… that is strange it doesn’t work for you. I am disabling hardware acceleration in this way:

where “isHardwareAccelerated” is set in proper res values, e.g. values-v14 to values-v20 (I am disabling hw for admob for all androdi 4.x.).

After this “fix” I don’t see any crash in libwebviewchromium.so.

I hoped you could confirm it

vkreal2 · July 27, 2018, 12:57am

@kds Yes I will try to confirm and get back. I am using combination of SDKBOX admob plugin and a custom one I built. Maybe the SDKBOX also need android:hardwareAccelerated to be set false.

@yinjimmy do you how I can set android:hardwareAccelerated for com.google.android.gms.ads.AdActivity that SDKBOX using for Admob plugin?

Thanks!

@kds Looks like the fix didn’t work for us. Disabled hardware acceleration from values-14 to values-20

how to reproduce this issue?
how many banner ad ?
could you plz share your sdkbox_config.json ?

As I know, too many webviews will cause this crash.

Thanks,

vkreal2 · July 29, 2018, 7:27am

how to reproduce this issue? We only see this on Play console.

could you plz share your sdkbox_config.json ?
