How to modify BuildConfig.java on my Android project?
提问by Emiliano Rodriguez
I'm working on an online course and i had these lines of code:
我正在上一门在线课程，我有以下几行代码：
String baseUrl = "http://api.openweathermap.org/data/2.5/forecast/daily?q=94043&mode=json&units=metric&cnt=7";
String apiKey = "&APPID=" + BuildConfig.OPEN_WEATHER_MAP_API_KEY;
URL url = new URL(baseUrl.concat(apiKey));
So, the API key apparently had to be set up on the BuildConfig.java file.
因此，显然必须在 BuildConfig.java 文件上设置 API 密钥。
I tried to do that, by adding this line of code to the BuildConfig.java file:
我试图通过将这行代码添加到 BuildConfig.java 文件中来做到这一点：
public static final String OPEN_WEATHER_MAP_API_KEY = 111111111111111111;
The first issue is that the string was saved without quotation marks and wouldn't let me compile.
第一个问题是字符串保存时没有引号，不会让我编译。
The second, and main issue is that i can't modify that file anymore. Every time i delete the line or add those missing quotation marks, and then try to compile, the line reverts to it's flawed version and compilation stops.
第二个也是主要的问题是我不能再修改那个文件了。每次我删除该行或添加那些缺少的引号，然后尝试编译时，该行都会恢复为有缺陷的版本并且编译停止。
I also get this message when i try to modify BuildConfig.java : "Generated source files should not be edited. The changes will be lost when sources are generated."
当我尝试修改 BuildConfig.java 时，我也收到此消息：“不应编辑生成的源文件。生成源时更改将丢失。”
Any help will be welcome.
欢迎任何帮助。

Values in BuildConfigcome from the build system. Custom BuildConfigvalues like OPEN_WEATHER_MAP_API_KEYcome from buildConfigFieldstatements in your build.gradlefile. The BuildConfig.javafile is off of your build/directory; files in there are generated by the build process and cannot be modified by hand. Instead, examine your build.gradlefiles and find where your API key is defined.
值BuildConfig来自构建系统。自定义BuildConfig值，例如OPEN_WEATHER_MAP_API_KEY来自文件中的buildConfigField语句build.gradle。该BuildConfig.java文件不在您的build/目录中；那里的文件是由构建过程生成的，不能手动修改。相反，检查您的build.gradle文件并找到您的 API 密钥的定义位置。

buildTypes.each { it.buildConfigField 'String', 'OPEN_WEATHER_MAP_API_KEY', "11111111111111111111111" }
put your API key inside ' '
将您的 API 密钥放在“ ”中
buildTypes.each { it.buildConfigField 'String', 'OPEN_WEATHER_MAP_API_KEY',' "11111111111111111111111"' }
and sync the gradle again, it'll solve the issue.
并再次同步gradle，它会解决问题。

I have just finished a similar course. I used the OpenWeatherMap API to. You need to get an APK Key from the OpenWeatherMap site. And put that in '1111111111111111111111111111111'
我刚刚完成了一个类似的课程。我使用了 OpenWeatherMap API。您需要从 OpenWeatherMap 站点获取 APK 密钥。并将其放入'11111111111111111111111111111111'
