Checking if Shared Preferences is encrypted

Question

I am encrypting the shared preferences with this code:

String masterKeyAlias = MasterKeys.getOrCreate(MasterKeys.AES256_GCM_SPEC);

   SharedPreferences sharedPreferences = EncryptedSharedPreferences.create(
       "secret_shared_prefs",
       masterKeyAlias,
       context,
       EncryptedSharedPreferences.PrefKeyEncryptionScheme.AES256_SIV,
       EncryptedSharedPreferences.PrefValueEncryptionScheme.AES256_GCM
   );

   // use the shared preferences and editor as you normally would
   SharedPreferences.Editor editor = sharedPreferences.edit();

Taken from this answer. I would like to know a programmatically method to check if the data is success encrypted. I try the above code to encrypt the shared preferences and don't show me any error.

From Android Studio, start Android Device Monitor, go to File Explorer,

and browse "/data/data/< name of your package >/shared_prefs/".

You will find the preferences XML there... and also you can copy it for inspection. you can see the xml contents (encrypted or decrypted)

You can implement the stetho library to view sharepreferences and many more things, such as databases or http calls, from the web browser.

Too easy
