title: Can I e-mail an apk file without creating a keystore/signing my application?
body: <p>I want to e-mail my apk file to someone. I started by just copying the <code>apk</code> file from my <code>/bin</code> folder, but when it was installed on the other device it got a <code>Parse Error</code>. I have been looking around SO and found some questions where people say to export the file. I started the export process but it is asking me to create a keystore. I'm not quite sure what that even is, but from what I have read it is how you sign your application. </p>
  
  <p>Is there anyway to send an apk file to someone without signing the application? </p>
  
  <p>If the user sets their tablet into debug mode, does the application need to be signed?</p>
  
  <p>It runs on my test device, is that because I am running it through eclipse?</p>
  
  <p>If I need to sign my application, is it a permanent move, or can I go back and edit what I have done?</p>
  
  <p>Thanks</p>
