Question 125784 in Android Studio Question posted in
The official documentation can be found here.

Android Studio – Caused by: com.google.crypto.tink.shaded.protobuf.InvalidProtocolBufferException: Protocol message contained an invalid tag (zero)

When launching an activity my app crashes at getEncryptedSharedPrefs:

    if(getEncryptedSharedPrefs().getString("pinSettingsLogin", "")!!.isEmpty()){
        getEncryptedSharedPrefs().edit()
            .putString("pinSettingsLogin" , "0000")
            .apply()
    }

With this error:

Caused by: com.google.crypto.tink.shaded.protobuf.InvalidProtocolBufferException: Protocol message contained an invalid tag (zero).

Weird thing is, this if statement works on Android 10 and 11 but not on Android 12. This if statement is here because in the ‘if’ below I check if the pinSettingsLogin = 0000 so that It goes to a new activity by it self.

    if(getEncryptedSharedPrefs().getString("pinSettingsLogin", "").equals("0000")){
        val i = Intent(this, SettingsActivity::class.java)
        startActivity(i)
        overridePendingTransition(R.anim.slide_in_right, R.anim.slide_out_left)
    }

     implementation "androidx.security:security-crypto:1.1.0-alpha04"

    Initialize sharedpreference like given in documentation:

     val keyGenParameterSpec = MasterKey.Builder(activity)
.setKeyScheme(MasterKey.KeyScheme.AES256_GCM)
.build()

        val sharedPref : SharedPreferences = EncryptedSharedPreferences
.create(activity,"secret_shared_prefs", keyGenParameterSpec, EncryptedSharedPreferences.PrefKeyEncryptionScheme.AES256_SIV,
            EncryptedSharedPreferences.PrefValueEncryptionScheme.AES256_GCM)

    This is a bug from EncryptedSharedPreferences, the issue happens on the initialization of the EncryptedSharedPreferences.
