Offline playback failed in Android 12 and 13 using Android SDK

technology · December 5, 2022, 4:58pm

I have setup a native module where we manage the download lifecycle when a video downloads. The code haven’t change so far and after testing the app in virtual and physical devices with android version 12 and 13 a NullPointer Exceptions comes up and checking the debugger after passing the _offlineSourceConfig to _player.load(), and printing out what the player loaded, it returns null. However this not happen with online playback neither happen with android with version below or same of 11.

Here an screenshot of the exception:

Hi @technology , thanks for reporting this behaviour. Can you please share the following information to help us take a closer look?

logcat output when this issue is observed.
Exact steps/user actions leading up to the reported behaviour.
Version of Bitmovin Android player SDK where issue is observed
Compiled and target Android version of the sample application build

Hi @lucky.goyal , Thanks for soon reply.

So I start answering the second numbered list, the steps are as follows:

We have a native module were we manage the downloads done in the react native layer, this works the way that when a user tab on download icon. a @ReactMethod in the native code triggers an instance of an OfflineContentManager that starts the listeners when getOptions() is called. When a download is successful, the offlineSourceConfig in send up through an event to React Native to eventually being kept in a database. When the user tabs on the downloaded videos and press on any video, the BitmovinVideoPlayerManager is called, passing in the @ReactProps the necessary config to play the video, in this case we send over the OfflineSourceConfigas a react prop, this is loaded in the player when is not null. Here the snippet code of that part:

        Source source;
        if (_offlineSourceConfig != null) {
            source = Source.create(_offlineSourceConfig);
        } else {
            source = Source.create(_sourceConfig);
        }
        _player.load(source);

This is working normally for android devices with android version lower that 11. however when I tested on an android phone with Android 12 or 13, I can see from logs (putting some printing outs everywhere) that when printing out _player.getSource() after runing _player.load(source); it returns a null value.

The curren bitmovin version SDK we are using is com.bitmovin.player:player:3.6.0
The compile and the Target SDK version we point to is 31.
The logcat using a virtual device with android 12.

So after some testing we realised that when the compile and target SDK java version was updated to 31 (which we needed in order that our app gets published in the play store) the issue is present, however when downgrade the SDK version (both compile and target) to 30 (it was the previous we were using), the offline playback was working correctly.

Hi @technology , thanks for providing additional insights. The mentioned behaviour could be related to a previously found Download functionality related bug when targeting Android SDK 31.

The bug is already fixed in Bitmovin player. Can you please test with latest Bitmovin player SDK 3.26.0 and verify if the issue is still happening?

Hi @lucky.goyal Thanks for the possible solution, however when trying to update bitmovind SDK this error triggers when trying to build the app.

More than one file was found with OS independent path 'META-INF/com.android.tools/proguard/coroutines.pro'

We haven’t got enable progard in release builds yet though.

Our workaround was downgrade the targetSdkVersion to the specific flavour that we want to the offline playback continue working.

Hi @technology , thanks for sharing this. The above error encountered with latest SDK seems related to the build environment and dependencies specially Kotlin and Gradle plugin.

Latest Bitmovin SDK has Kotlin 1.7.20 as dependency
The player version 3.18.0 which has the fix for Download use case for target API 31 has Kotlin 1.6.10 as dependency
The player version 3.6.0 used in your app has Kotlin 1.5.10 as dependency.

Upgrading Kotlin and/or gradle plugin to later version may help resolve the build issue. You can also try with version 3.18.0 (if the build works) instead of latest SDK and check the Download use case behaviour when targeting API 31.
