how to change android app name in the build gradle file - gradle

Question

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 .

Answer 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.

Answer 2

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.

Answer 3

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.

Answer 4

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"]
}
}
