Find Debug Hash key using Code

If you get a debug hash key from using Code in Android, you must try this code.

try {
	PackageInfo info = getPackageManager().getPackageInfo(getPackageName(), PackageManager.GET_SIGNATURES);
	for (Signature signature : info.signatures) {
		MessageDigest md = MessageDigest.getInstance("SHA");
		md.update(signature.toByteArray());
		Log.e("MY KEY HASH:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
	}
} catch (NameNotFoundException e) {
	Log.e("KEY HASH ERROR:", "NameNotFoundException: " + e.getMessage());
} catch (NoSuchAlgorithmException e) {
	Log.e("KEY HASH ERROR:", "NoSuchAlgorithmException: " + e.getMessage());
}
