Source: https://developer.samsung.com/one-ui/comp/dialog

This code snippet demonstrates how to create and display an AlertDialog in Android, specifically positioning it at the bottom of the screen using `Gravity.Bottom`. It requires basic Android development knowledge and the Android SDK.

```java
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("Title");
        .setMessage("Message");
        .setPositiveButton("OK", null);
        .setNegativeButton("Cancel", null);

AlertDialog alertDialog = builder.create();
alertDialog.getWindow().setGravity(Gravity.Bottom);
alertDialog.show();
```
