Summary: CB-12015 Causes text to not render on Android 4.4.4
Key: CB-12939
URL: https://issues.apache.org/jira/browse/CB-12939
Project: Apache Cordova
Issue Type: Bug
Components: cordova-android
Affects Versions: [email protected]
Environment: Android 4.4.4 on Nexus 7 (2013)
[email protected]

Windows 10 15063.413
Reporter: Adam Venezia

I've been able to nail this down in my app, but not in a bare reproduceable
app, unfortunately, but I know exactly what to comment out to make the issue go
away.
My Cordova app uses a custom font (woff or ttf exhibited this), declared in my
CSS file, and applied to the body tag so all text uses it. When the app
launches, several text fields do not render, the text is invisible. Rotating
the device causes the text to reappear. Attaching to Chrome debug tools causes
it to reappear. Not using the custom font, such as defaulting to Arial, the
text appeared just fine.
Android 5.x, 6.x, and 7.x don't appear affected; even worse, the Visual Studio
Android Emulator for 4.4 (x86) does not exhibit the issue, nor does the Google
Emulator for 4.4 (ARM) exhibit the issue. I did a hard reset of my Nexus 7 on
4.4.4 and the issue still arose.
I started using older versions of cordova-android, and started with 6.0.0.
6.0.0 = worked
6.1.2 = worked
6.2.0 = worked
6.2.1 = worked
6.2.2 = worked
6.2.3 = broken
Comparing 6.2.2 with 6.2.3, I discovered this code in SystemWebViewEngine.java
// Enable scaling
// Fix for CB-12015
settings.setUseWideViewPort(true);
settings.setLoadWithOverviewMode(true);
Viewing the bug entry here on Jira, seems like that does fix some people having
a different issue with viewport scaling. However, when I comment out those 2
lines of code, my issue goes away. That makes things a little sticky.
