Key hash for Facebook Android SDK

Question

I can\'t figure out how to get the Key Hash required to use the Facebook Android SDK. I figured out that I can use keytool with these commands:

Answer 1

you can use code below to get the Hash key :

try {

   PackageInfo info = getPackageManager().getPackageInfo(getPackageName(), PackageManager.GET_SIGNATURES);

   for (Signature signature : info.signatures) 
   {
    MessageDigest md = MessageDigest.getInstance("SHA");
    md.update(signature.toByteArray());
    Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
   }

  } catch (NameNotFoundException e) {
   Log.e("name not found", e.toString());
  } catch (NoSuchAlgorithmException e) {
   Log.e("no such an algorithm", e.toString());
  }
