Android facebook sdk internal utility java.lang.AssertionError

Question

I have been using version 4.27.0 of facebook sdk for android. I have been getting a crash only for android 8+ devices. The stack trace is as follows:

Fatal Exception: java.lang.AssertionError: No NameTypeIndex match for SHORT_DAYLIGHT
       at android.icu.impl.TimeZoneNamesImpl$ZNames.getNameTypeIndex(TimeZoneNamesImpl.java:724)

I have searched for this over the web but couldn't get anything useful. Please provide some pointers here.

Answer 1

I am facing this issue too, upgrade the Facebook SDK to the latest (Facebook Android SDK 4.35), they have added a workaround for this issue:

 private static void refreshTimezone() {
    try {
        TimeZone tz = TimeZone.getDefault();
        deviceTimezoneAbbreviation = tz.getDisplayName(
                tz.inDaylightTime(new Date()),
                TimeZone.SHORT
        );
        deviceTimeZoneName = tz.getID();
    } catch (AssertionError e) {
      // Workaround for a bug in Android that can cause crashes on Android 8.0 and 8.1
    } catch (Exception e) {
    }
}
