Android Application Security

I want to develop an application in which user data is very sensitive. I am new to dev. therefore, I am not sure that the following methods are necessary to ensure safety or effectiveness. Please leave a comment. Thanks in advance.

  • For added security, we can avoid the market (game store) and install the application on a separate device. Does it make it safer?

  • I need to store data on the device. How can we protect data so that other applications cannot read it?
