Input instructions on Android

When a label might not describe the requested input sufficiently, you should add additional instructions. For example, if passwords are required to be at least 8 characters, indicate this to users.

On Android, you can use a TextView to show instructions.

You can also use a TextInputLayout, which contains a setHelperText method to provide instructions. To show instructions, you need to set setHelperTextEnabled to true.

input.setHelperText("Your password should be at least 8 characters.")
