如何知道 Parse.initialize() 何时已被调用? [英] How to know when Parse.initialize() has already been called?

问题描述

现在我使用静态布尔值来判断初始化何时发生.有没有更简单的方法可以知道我已经调用了初始化?

Right now I am using a static boolean to tell when the initialization has occurred. Is there an easier way to know that I have already called initialize?

谢谢！！！

解决了！！！！非常感谢您的评论.您需要在扩展应用程序的类中初始化解析，然后将其作为应用程序(而不是其他活动)添加到清单文件中.

SOLVED!!!! Thank you so much for your comments. You need to initialize parse in a class that extends an application, and then add it to the manifest file as an application (not an other activity).

:)

这是我使用 Parse 的类:

This is my class to use Parse:

package com.example.myapp;

import com.parse.Parse;

import android.app.Application;

public class UseParse extends Application {
@Override
public void onCreate() {
super.onCreate();
Parse.initialize(this, "id", "key");
 }
}

这是我的安卓清单文件

推荐答案

创建一个应用程序类并在 onCreate 中初始化解析.

Make a Application Class and in onCreate initialize parse.

public class YourApplication extends Application {
@Override
public void onCreate() {
    super.onCreate();
    Parse.initialize(this, "id","key");
    }
}

在此之后它不会被一次又一次地调用.

After this it wont be called again and again.

也在你的清单中声明它

<application
    android:name="com.you.yourapp.YourApplication "

这是您初始化它的唯一地方.而不是在登录活动或其他任何地方.

This is the only place where you initialize it. And not in the Login Activity or anywhere else.
