Answer 1

Siddharth's solution 2 sometimes isn't possible in Facebook SDK 3.0 onwards. Use the following code to toast the right key hash inside your app itself.

try {
            PackageInfo info =     getPackageManager().getPackageInfo("com.package.mypackage",     PackageManager.GET_SIGNATURES);
            for (Signature signature : info.signatures) {
                MessageDigest md = MessageDigest.getInstance("SHA");
                md.update(signature.toByteArray());
                String sign=Base64.encodeToString(md.digest(), Base64.DEFAULT);
                Log.e("MY KEY HASH:", sign);
                Toast.makeText(getApplicationContext(),sign,     Toast.LENGTH_LONG).show();
            }
} catch (NameNotFoundException e) {
} catch (NoSuchAlgorithmException e) {
}

replace com.package.mypackage with your package name...
