Can't find layout ID for < 1% of users?

Question

I have an app which gets several thousand users a day. I'm getting a handful of reports through marketplace that my entry activity can't load its layout xml resource. I don't see how this could be possible?:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.me.app/com.me.app.MyActivity}: **android.content.res.Resources$NotFoundException: Resource ID #0x7f030065**

... 11 more

The exception points to this line:

setContentView(R.layout.my_layout);

Any ideas what I could be doing wrong here? Again, for 99% of users, no problem.

Thank you

Answer 1

I agree with the comments on the question that troubleshooting resource ID 0x7f030065 is the key to understanding these error reports.

I'm assuming that resource is NOT the my_layout file. Despite my_layout being pointed to as the line of the problem, it most likely is not the root issue. Something inside the my_layout file is referring to resource 0x7f030065. The layout inflater often does not report these errors very clearly.

If there isn't a version of 0x7f030065 in a default folder (ex: drawable instead of drawable-landscape), then perhaps the 1% is running in a configuration that can't find it is falling back to the non-existent default. This could be possible even if your app is locked in landscape orientation for instance - occasionally a portrait draw could still happen - even if it's not visible to the end user.

Is it always the same resource id? That's a good thing to pay attention to.

In my experience, other issues like running out of memory can cause these sorts of inflate time exceptions. If resource 0x7f030065 refers to a custom layout class, then anything that happens in the constructor of that class could possibly result in a Resources$NotFoundException

I have experienced something similar. I was having an activity that I wanted to show only in landscape - so in AndroidManifest.xml I had android:screenOrientation="landscape". Than a folder layout-land and there my layout file.

From time to time, randomly, I was getting a Resources$NotFoundException when the activity was trying to load the main layout.

I solved it by renaming folder layout-land to layout.

But I think we hit some kind of bug in android.
