title: What is the use of debug.keystore in android?
body: <p>i have a small clarification. i have the following question, </p>
  
  <p>1.Whether the debug.keystore is used to generating the apk every time building the project normally?</p>
  
  <p>2.I have done unzip the generated apk file. I came to see certificates are available in META-INF folder. Are these certificates generated with debug.keystore to identify the system identification?. Because, Both SHA1 hash values are same in debug.keystore and cert.RSA of unzipped apk.</p>
  
  <p>Please clarify this doubt.</p>
  
  <p>Thanks in advance..</p>
