Explanations

For each API end points you have to send some POST data

posts.php: no POST data required

create RegisterActivity yourself by referring LoginActivity
Don't forget to change the package name and class names if necessary when you copy files to your project.
You need to add third party library using gradle dependencies in build.Gradle(Module app) file

compile 'com.mcxiaoke.volley:library:1.0.18'compile 'com.android.support:recyclerview-v7:23.0.1'
