EncryptedSharedPreferences Deprecated! Now What?
summary
AndroidX EncryptedSharedPreferences (androidx.security:security-crypto) is deprecated in 1.1.0-alpha07. Migration options are: use the Android Keystore directly via JCA/provider="AndroidKey", implement AEAD yourself with AES‑GCM and a 12‑byte IV, or use Tink’s newer AndroidKey helpers while avoiding deprecated Tink APIs. Because OEM keystore bugs have caused 459 crash reports and master‑key corruption, migrate by exporting all stored values, re‑encrypting with the new key material, deleting old master key files, handling exceptions, and forcing logout/recreation of keys on failure.
