IOException|RemoteException

Error message

IOException|RemoteException

What it means

For a genuine (DRM-protected) APKM, ApkFile streams the URI into an .apks cache file and runs unApkm.decryptFile; an IOException (read/write failure on stream or cache) or RemoteException (the bundled decryption provider/service died or was unbound) aborts the conversion, wrapped as ApkFileException. Faulty input: the APKM stream or the decryption service binding.

Solutions

1. Ensure enough free cache space and retry the conversion
2. Verify the unApkm decryption provider is available and not killed by battery optimizations
3. Handle DRM-protected APKM by asking the user to obtain a DRM-free copy
