是否可以在 Gradle 中声明一个可在 Java 中使用的变量?基本上我想在 build.gradle 中声明一些变量,然后在构建时(显然)得到它.就像 C/C++ 中的预处理器宏...
Is it possible to declare a variable in Gradle usable in Java ? Basically I would like to declare some vars in the build.gradle and then getting it (obviously) at build time. Just like a pre-processor macros in C/C++...
声明的一个例子是这样的......:
An example of declaration would be something like that ... :
android {
debug {
A_VAR_RETRIEVABLE_IN_JAVA = 42
}
release {
A_VAR_RETRIEVABLE_IN_JAVA = 42+52
}
}
有没有办法做这样的事情?
Is there a way to do something like that ?
这里有两种从 Gradle 传递值以在 Java 中使用的方法;
Here are two ways to pass value from Gradle to use in Java;
android {
buildTypes {
debug {
buildConfigField "int", "FOO", "42"
buildConfigField "String", "FOO_STRING", ""foo""
buildConfigField "boolean", "LOG", "true"
}
release {
buildConfigField "int", "FOO", "52"
buildConfigField "String", "FOO_STRING", ""bar""
buildConfigField "boolean", "LOG", "false"
}
}
}
您可以使用 BuildConfig.FOO
android {
buildTypes {
debug{
resValue "string", "app_name", "My App Name Debug"
}
release {
resValue "string", "app_name", "My App Name"
}
}
}
您可以使用 @string/app_name
或 R.string.app_name
