Question

当我将Facebook集成到我的Android应用程序中时，我没有在Logcat中获得KeyHash，而是获得了一些其他键

public class HomeActivity extends AppCompatActivity {
private EditText editText_Email,editText_Password;
private Button button_login,button_fbinteglogin;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_home);
  //  editText_Email = findViewById(R.id.editText_email);
  //  editText_Password = findViewById(R.id.editText_password);

    try {
        PackageInfo info = getPackageManager().getPackageInfo("com.example.alimuhammad.fbintegapp", 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 (PackageManager.NameNotFoundException e) {
        e.printStackTrace();
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    }

}
}

搜索KeyHash时Logcat的结果，什么都没有显示，但是当我编写一个键时，发现下面的结果。现在该怎么办？

将应用程序与Facebook集成时，我没有获得KeyHash值
