[android-developers] Re: MediaPlayer suddenly stopped working in Android 4.2

I have now verified this same error pops up on a Nexus 10 as well... so now we've got it happening on all three (Nexus 4, 7, 10), which is a pretty good indication that it's a problem in the MediaPlayer in Android 4.2.x.

This really needs the attention of a google engineer.

Apparently I'm not the only one seeing this:

I'm about to do some tests to see if its relate to the encoding of the MP3 file, however it it worked in android 4.1 it should also work in android 4.2.

For some reason the MediaPlayer starts generating an error in Android 4.2 when it has been working just fine until now.

Nobody seems to know what has changed or how to work around it. The only suggestions I've found so far are to do with permissions, but unless they have changed radically for external storage, the MediaPlayer should have permission to read the files.

Here is some relevant information. Notice there is no stack trace, just a message printed out.

(I've included some of my debugging output for reference).

So far I have seen this on both a Nexus 7 and a Nexus 4 running JB 4.2.1, it seems to work fine for the prior versions that I've been able to test (4.0.4, 4.1.1).
