getInstance returns NoSuchAlghoritmExeptoin, although when checked by the operator, one of them is AndroidOpenSSL: Cipher. AES/ECB/PKCS5Padding

    Cipher cipher;
    cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");

NoSuchAlghoritmExeption happens when you don't have that algorithm on your device environment.

Well, the first question here is - why do you need ECB? It has a bunch of disadvantages

Have you tried the CBC? It will work probably on all Android environments. My steps would be next:

Try to use CBC instead of EBC, it also has PKCS5Padding, Cipher.getInstance("AES/CBC/PKCS7PADDING")
Verify if the result matches your expectation
Go through the docs and verify what algorithms are supported in Cipher
Find libraries with support of needed algorithms

Describe your issue in a more detailed way, please.
