如何生成字符串类型的 buildConfigField

问题描述

在我的 Android Studio 项目中有两个 build configuration 和一些 buildConfigField:

In my Android Studio project there are two build configuration with some buildConfigField:

    buildTypes {
    def SERVER_URL = "SERVER_URL"
    def APP_VERSION = "APP_VERSION"

    debug {
        buildConfigField "String", SERVER_URL, "http://dev.myserver.com"
        buildConfigField "String", APP_VERSION, "0.0.1"
    }

    release {
        buildConfigField "String", SERVER_URL, "https://myserver.com"
        buildConfigField "String", APP_VERSION, "0.0.1"

        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

我得到如下错误:

/path/to/generated/BuildConfig.java
    Error:(14, 47) error: ';' expected
    Error:(15, 47) error: ';' expected

生成的BuildConfig.java如下:

public final class BuildConfig {
    public static final boolean DEBUG = Boolean.parseBoolean("true");
    public static final String APPLICATION_ID = "com.mycuteoffice.mcoapp";
    public static final String BUILD_TYPE = "debug";
    public static final String FLAVOR = "";
    public static final int VERSION_CODE = 1;
    public static final String VERSION_NAME = "1.0";
    // Fields from build type: debug
    public static final String APP_VERSION = 0.0.1;
    public static final String SERVER_URL = http://dev.mycuteoffice.com;
}

我认为 APP_VERSION 和 SERVER_URL 没有正确生成，因为它们是没有引号的字符串类型.

I think the APP_VERSION and SERVER_URL are not getting generated properly as being String type they do not have quotes.

我不确定为什么会以这种方式生成它.请让我知道如何解决此问题.

I am not sure why it is being generated in such a way. Please let me know how can I resolve this issues.

推荐答案

字符串类型的构建配置字段应该这样声明:

String type build config fields should be declared like this:

buildConfigField "String", "SERVER_URL", ""http://dev.myserver.com""

引号中的字段名称，转义引号中的字段值.

the field name in quotes, the field value in escaped quotes additionally.
