android - 注册结束时发生 Logcat 错误

Question

我无法注册到我的应用程序。因此我无法登录我的应用程序。下面我发布了与此相关的代码。

登录.java:

package com.steph.register;

public class Login extends Activity {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // Set up the login form.
        setContentView(R.layout.login);
        mEmailView = (EditText) findViewById(R.id.email);
        mPasswordView = (EditText) findViewById(R.id.password);
        // Action listener to focus on the login process based on the key input.
        mPasswordView
                .setOnEditorActionListener(new TextView.OnEditorActionListener() {
                    @Override
                    public boolean onEditorAction(TextView textView, int id,
                            KeyEvent keyEvent) {
                        if (id == R.id.login || id == EditorInfo.IME_NULL) {
                            attemptLogin();
                            return true;
                        }
                        return false;
                    }
                });


    //Method to clear the registration details.
    private void clearRegistrationCredinals() {
        mRegisterEmailView.setText(null);
        mRegisterPasswordView.setText(null);
        mRegisterRePasswordView.setText(null);
    }
    }

}

然后我收到一条这样的日志猫消息:

日志:

• 但是 Logcat 错误没有指向任何行。我不知道怎么办解决这个问题。任何人都可以帮我解决这个问题。谢谢。

看到目前 api 不工作......

//Perform user registration task using AsyncTask in the background.
public class UserRegisterTask extends AsyncTask<Void, Void, String> {
    @Override
    protected String doInBackground(Void... params) {
        Logger.debug("UserRegisterTask", "doInBackground");
        try {
    //      String url = Settings.baseUrl + "users";
            JSONObject oJSONObject = new JSONObject();
            oJSONObject.put("email", mEmail);
            oJSONObject.put("username", mEmail);
            oJSONObject.put("password", mPassword);
            oJSONObject.put("password_confirmation", mPassword);
            //Make a Post method to create the new user.
    //      Users usr = JsonManager.parseUser(HttpManager.post(url,
    //              oJSONObject));
            /*if (usr.getUserID() != 0) {
                UserManager.setUserDetails(getApplicationContext(), usr);
                return "Success";
            }*/

        } catch (Throwable th) {
            Logger.error(th);
        }
        return "Success";
    }

您没有初始化 usr 变量，但您正在尝试从中获取数据。所以我评论那个代码。现在可以了。
