问题描述

我是一个新的开发探索了Android的世界。我目前正在通过Udacity教程创建阳光的应用程序。在为了得到openweathermap我必须从我的帐户添加API密钥我到生成的URL月底的数据片段活动类。有一个在片段活动调用BuildConfig.java（点击查看调用BuildConfig.java这是六号线为String apiKey的一部分）。

I am a new developer exploring the world of Android. I am currently working through the Udacity tutorials for creating the Sunshine app. In the fragment activity class in order to get data from openweathermap I must add the API key I got from my account to the end of the generated URL. There is a call to BuildConfig.java in the Fragment activity (click to see the call to BuildConfig.java which is on the 6th line as part of String apiKey).

该build.gradle文件如下：

The build.gradle file is as follows:

apply plugin: 'com.android.application'
android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"
    defaultConfig {
        applicationId "com.example.android.sunshine.app"
        minSdkVersion 10
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }

    }
    buildTypes.each {
        it.buildConfigField 'String', 'OPEN_WEATHER_MAP_API_KEY', 'c882c94be45fff9d16a1cf845fc16ec5'
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.1.0'
}

在buildTypes.each it.buildConfigField被称为与字符串'，'OPEN_WEATHER_MAP_API_KEY'，'c882c94be45fff9d16a1cf845fc16ec5造成

in buildTypes.each it.buildConfigField is called with 'String', 'OPEN_WEATHER_MAP_API_KEY', 'c882c94be45fff9d16a1cf845fc16ec5' resulting in

public static final String OPEN_WEATHER_MAP_API_KEY = c882c94be45fff9d16a1cf845fc16ec5;

正在BuildConfig.java产生的，不过，我不断收到此错误： 不能解析符号（点击查看错误信息和BuildConfig.java文件） 我不明白为什么字符串OPEN_WEATHER_MAP_API_KEY会自动被创建为只是一组字母和数字没有他们周围的报价，但如果我编辑code阅读：

being generated in BuildConfig.java, however I keep getting this error: Cannot Resolve Symbol (click to see error message and BuildConfig.java file) I do not understand why the String OPEN_WEATHER_MAP_API_KEY is automatically being created as just a group of letters and numbers without quotes around them, but if I edit the code to read:

public static final String OPEN_WEATHER_MAP_API_KEY = "c882c94be45fff9d16a1cf845fc16ec5";

或

public static final String OPEN_WEATHER_MAP_API_KEY = 'c882c94be45fff9d16a1cf845fc16ec5';

在BuildConfig.java自动改变自己。 我不知道我做错了，我查了许多Udacity的视频时并没有对这个问题的任何信息。请让我知道，如果你知道如何解决这个问题。

the BuildConfig.java automatically changes itself. I am not sure what I am doing wrong and I checked many of the Udacity videos which did not have any information about this issue. Please let me know if you know how to fix this.

问候。

推荐答案

修改

 buildTypes.each {
     it.buildConfigField 'String', 'OPEN_WEATHER_MAP_API_KEY', 'c882c94be45fff9d16a1cf845fc16ec5'
 }

与

 buildTypes.each {
     it.buildConfigField 'String', 'OPEN_WEATHER_MAP_API_KEY', "\"c882c94be45fff9d16a1cf845fc16ec5\""
 }

这样 OPEN_WEATHER_MAP_API_KEY 应正确转义
