title: Are my passwords safe in an apk
body: <p>Let's say I want to access an online database from my android app. I will have to enter my username and password. But are my credentials safe if I do this?
  Would it be possible for a hacker to decompile my apk and get the password for example?
  If it isn't safe, what should I do, send a request to a php script on a private server?</p>
