Why Encrypt Java Strings in Android Apps

Using Appdome’s Strings and Resources Encryption you can easily encrypt all java strings and the assets folder in Android apps. This feature greatly enhances the security of the app against malicious attempts to read the app’s contents or harvest valuable data about mobile users.

In addition, with Appdome’s XMLEncryptTM you can easily encrypt the sensitive strings stored in the localizable locations in Android apps. Nevertheless, we recommend moving Google API keys into a java const string within the app’s code, where it will be encrypted by Appdome Strings Encryption.
