| # Android Hello World |
| |
| This is a simple app that allows encrypting and decrypting strings |
| with keys stored in private shared preferences. On Android M or newer |
| the keys are further encrypted with a master key stored in Android |
| Keystore. |
| |
| It demonstrates the basic steps of using Tink, namely generating or |
| loading key material, obtaining a primitive, and using the primitive |
| to do crypto. It also shows how one can add a dependency on Tink |
| using Gradle. |
| |
| The easiest way to build this app is to import it to Android Studio. You can |
| also |
| [build it from the command line](https://developer.android.com/studio/build/building-cmdline). |
