how to change android app name in the build gradle

问题:

I'm creating different flavors using gradle for 2 small android apps ,i wanna just know if i can edit app name on the xml file in the build.gradle , for my different flavors .

回答1:

What do you mean by app name? the application package name in the manifest or the application name as it appears in the launcher?

If the former, do:

android {
  productFlavors {
    flavor1 {
      packageName 'com.example.flavor1'
    }
    flavor2 {
      packageName 'com.example.flavor2'
    }
  }
}

It's possible to override the app name as well but you'd have to provide a flavor overlay resource instead.

So create the following files:

• src/flavor1/res/values/strings.xml
• src/flavor2/res/values/strings.xml

And in them just override the string resource that contains your app name (the one that your manifest use for the main activity label through something like @string/app_name). You can also provide different translations as needed.

You can use resValue, eg.

debug {
    resValue 'string', 'app_name', '"MyApp (Debug)"'`
}
release {
    resValue 'string', 'app_name', '"MyApp"'
}

Make sure your AndroidManifest uses android:label="@string/app_name" for the application, and remove app_name from strings.xml as it will conflict with gradle's generated strings.xml when it tries to merge them.

Actually... For a more definitive explanation;

In main build.gradle :

ext {
    APP_NAME = "My Fabulous App"
    APP_NAME_DEBUG = "My Fabulous App debug"
}

In app build.gradle :

android {
    buildTypes {
        debug {
            manifestPlaceholders = [appName: APP_NAME_DEBUG]
        }
        release {
            manifestPlaceholders = [appName: APP_NAME]
        }
    }
}

so in AndroidManifest.xml

<application
    ...
    android:label="${appName}"
    >

is possible. Voilà! you have different application names for release and debug.

This answer is based on Tom's, it works the best and you can work with gradle.properties to allow further animation in build process.

In build.gradle:

debug {
  resValue 'string', 'app_name', APP_NAME
}

In gradle.properties:

APP_NAME="Template 1"

Manifest

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="com.myapp"> 


<application
    tools:replace="android:label"
    android:label="${appName}"
    android:theme="@style/AppTheme">

 <activity
    android:name=".MainActivity"      
    android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
    android:label="${appName}"
    android:windowSoftInputMode="adjustResize">
    <intent-filter>
         <action android:name="android.intent.action.MAIN" />
         <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>

Gradle

buildTypes {
    release {
         minifyEnabled enableProguardInReleaseBuilds
         proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
         signingConfig signingConfigs.release
//       manifestPlaceholders = [appName: appConfig.appName]
         manifestPlaceholders = [appName: "Your app Name"]

    }

    debug {
         signingConfig signingConfigs.release
//       manifestPlaceholders = [appName: appConfig.appName]
         manifestPlaceholders = [appName: "Your app Name"] 

    }
}
