1189236 - crash in java.lang.NullPointerException: Attempt to invoke virtual method ''boolean java.lang.String.equals(java.lang.Object)'' on a null object reference at org.mozilla.gecko.webapp.WebappImpl.onTabChanged(WebappImpl.java)

Status: RESOLVED WONTFIX

(Firefox for Android Graveyard :: Web Apps (PWAs), defect)

Description

[Martijn Wargers (dead)]

I created this loop client apk, using the mozilla-apk-cli (I did do something like in bug 989041, comment 10 but then for the loop-client), it's here:
http://people.mozilla.org/~mwargers/apks/loop-client.apk

I installed that and opened it, using a Nightly Fennec build.
Then I noticed there was a notification called "Firefox Hello-debugging activated" or something, I tapped on that notification.
Then, I got this crash report:

This bug was filed from the Socorro interface and is 
report bp-ed2c773f-fef2-4fe0-9869-1bfb92150730.

Myk, is this a valid bug report? Is this a bug in Fennec or in the mozilla-apk-cli?

Yes, it's a valid bug report, since your app shouldn't be able to crash Fennec.  I think it's a bug in Fennec itself (more specifically: a bug in its webapp feature) rather than a bug in mozilla-apk-cli.

Per bug 1235869, we're going to disable the Android web runtime, so we won't fix this bug in it.

(This is part of a bulk resolution of bugs in the Firefox for Android::Web Apps component, from which I attempted to exclude bugs that are not specific to the runtime, but it's possible that I included one accidentally.  If so, I'm sorry, and please reopen the bug!)
