ExoPlayer: DrmSession$DrmSessionException: java.lang.IllegalArgumentException: Failed to restore keys: BAD_VALUE

Bug

Hi!

DrmSession$DrmSessionException: java.lang.IllegalArgumentException: Failed to restore keys: BAD_VALUE occurs when trying to play downloaded content offline using the ExoPlayer library version 2.18.2.

Log attached. If you need to provide additional information about the implementation or other logs, I will be happy to help resolve the issue.

The problem is compounded by the fact that the bug only reproduces on Samsung S23 / S23 Ultra devices, but does not reproduce on other real devices and on emulators.

Ideas, hypotheses, assumptions?

Thanks in advance for your reply.

We have identified the issue and are working on making the patch available to OEM partners. They will need to pick up the patch and include it in an upcoming update. We also let Samsung know about this and see if we can update this tracker with information about availability of an update.

rrfrias on Sep 5, 2023

@rrfrias I sent a new batch of resources and observations via email.

In the Google Drive link from the email you’ll find:

  • The source code for a sample app that is prepared to reproduce the issue (I did not share it here as it contains credentials to access a test account on our api)
  • Videos:
    • Video 1 - Shows the app on Android 13 (where the issue is reproduced).
    • Video 2 - Observations from video 1 and log analysis: You can see that some native c++ logic deletes all the downloaded licenses up until the point when the function is triggered. In my case, I expected to have 231 downloaded licenses at the end of the test, but I only got 30, that’s because, as you can see in the logs, the first 201 licenses were automatically removed. I don’t know what triggers this, and why it doesn’t happen on Android 11 or below, but this is the root cause of my issue - i.e. Failed to restore keys: BAD_VALUE error when attempting to play content and the license file is not found.
    • Video 3 - Shows the same test as Video 1, but this time running on Android 11 - here you can see that licenses are not removed, which is the behavior I expect on all Android versions.
  • Adb bugreport for the test that ran in video 1

The exact logs that leave a clue to what’s happening - found in the bugreport log file:

It’s easier to see what’s happening in real time if you gain root access to the emulator and then navigate to the directory where licenses are saved:

adb root
adb shell
cd /data/vendor/mediadrm/IDM1013/L3

You can use this command to query how many licenses are saved (assuming you are in the L3 directory):

ls -1 ksid* | wc -l

If you want to check the I/O activity in real time, use this command - this monitors operations on files that contain “ksid” in the name:

inotifyd - . | grep ksid

If you want to save the output and analyze it later, use this:

inotifyd - . | grep ksid > /sdcard/inotifyd_1.txt 2>&1

Then press the download button, wait for it to finish and then exit the process. Get the inotifyd_1.txt and check when files are deleted (unexpectedly). Here is the table from the help menu that maps letters to I/O operations: Screenshot 2023-08-19 at 09 43 57

In video 1 at 2:27, exactly when the logs in the phone show Chapter 201, watch the top terminal from the background, it is filled with d (Delete) operations for all licenses.

Reproduced with Android Emulator (Pixel XL arm64-v8a API 33 on Mac M1 Pro host) - full build numbers shown in the videos.

According to error reports from users, the Failed to restore keys: BAD_VALUE error happens only on Android 12 and up, so this is congruent with the test results from above:

Screenshot 2023-08-21 at 21 39 28

Do you know why this is happening?

Do you know if Samsung made any progress on adopting this fix in their OS updates.

I forgot to answer this part of the question. Samsung is working on integrating fixes. It might be in android 14 updates for some of these devices. We will check with them after they have completed integration, for dates for when users should expect to see updates.
