Expansion file stopped working when update apk

Question

Recently updated an APK and chose the option to reuse the expansion file (with videos).

Old version

1(1.0.0) -> main.1.br.com.myapp.obb

New version

2(1.0.1) -> selected the same

The application has been updated and usually recognized the file expansion. But when you play the video the following error occurs:

E/AndroidRuntime(12752): java.lang.NullPointerException
E/AndroidRuntime(12752): at com.android.vending.expansion.zipfile.APEZProvider.openAssetFile(APEZProvider.java:182)

Does anyone have a solution to this problem ?

Thanks a lot

Problem solved!

Was necessary to add the tags <meta -data> in AndroidManifest to inform the version of OBB file.

<provider
    android:name="br.com.appname.provider.ProviderVideoZipUri"
    android:authorities="br.com.appname.provider.ProviderVideoZipUri"
    android:exported="false">

    <meta-data android:name="mainVersion" android:value="1"></meta-data>
    <meta-data android:name="patchVersion" android:value="2"></meta-data>
</provider>
