title: Android: The ways to change build.prop
body: <p>I need to build an application which enables me to edit the build.prop by using my own application. This is to optimize some of the values in the build.prop. Of course, I can edit this file using a file manager with root access. But my problem is, I need to edit this using an application that I create, and make it easy for the novice users to edit the file with recommended settings by my application. Please help me figure out this. Thanks for you time!</p>
