流程状态 - 阻塞状态(Process states - blocked state)

 我刚刚在这里针对不同的productFlavors回答了类似的问题。 
 
 在你的情况下它是调试/生产。 我不知道为什么你需要在生产和调试之间切换，但我认为你可以像我提出的口味一样。 
 
 创建两个额外的文件夹src/release和src/debug ，在每个文件夹中放置相应的google-services.json ，这样你就可以： src/release/google-services.json和src/debug/google-services.json 
 
 现在在gradle添加这个： 
 
android {

// set build config here to get the right gcm configuration.
//def myBuildConfig = "release"
def myBuildConfig = "debug"

// this will copy the right google-services.json file to app/ directory.
if (myBuildConfig.equals("release")) {
    println "--> release copy!"
    copy {
        from 'src/release/'
        include '*.json'
        into '.'
    }
} else {
    println "--> debug copy!"
    copy {
        from 'src/debug/'
        include '*.json'
        into '.'
    }
}

// other stuff
}

I have just answered a similar question here for different productFlavors. 
 
In your case it's debug/production. I don't know why you need to switch between production and debug but i think you can do the same as what I proposed for flavors.
 
Create two extra folders src/release and src/debug , in each of the folders you put the corresponding google-services.json , so you will have: src/release/google-services.json and src/debug/google-services.json
 
Now in gradle add this :
 
android {

// set build config here to get the right gcm configuration.
//def myBuildConfig = "release"
def myBuildConfig = "debug"

// this will copy the right google-services.json file to app/ directory.
if (myBuildConfig.equals("release")) {
    println "--> release copy!"
    copy {
        from 'src/release/'
        include '*.json'
        into '.'
    }
} else {
    println "--> debug copy!"
    copy {
        from 'src/debug/'
        include '*.json'
        into '.'
    }
}

// other stuff
}
