Set android app version from command line

I'm trying to set android app version code and name using project variables on running:
./gradlew bundleRelease -PversionName=1.0.0 -PversionCode=100
To use this on my app/build.gradle file:
defaultConfig {
versionCode project.versionCode
versionName project.versionName
[...]
}
I remember to use this once, but this time I'm receiving the following weird error:
A problem occurred evaluating project ':app'.
> No signature of method: build_3d8oq36p9lc2a0ylsa4yduj2n.android() is applicable for argument types: (build_3d8oq36p9lc2a0ylsa4yduj2n$_run_closure1) values: [build_3d8oq36p9lc2a0ylsa4yduj2n$_run_closure1#6e40553b]
How can I set the app version code and name with gradle on the command line?

Thanks, #akif for the help!
defaultConfig {
versionCode project.versionCode.toInteger()
versionName project.versionName
[...]
}

Upload apk to existing play store project after adding flavors

I want to upload a new version of my app, but I can't because I added flavors so the package name has changed from:
com.myapp.android
to
com.myapp.android.flavor1
Inside my build.gradle:
productFlavors {
main {
applicationId 'com.myapp.android'
versionName '1.0'
versionCode 4
}
flavor1 {
applicationId 'com.myapp.android.flavor1 '
versionName '1.0'
versionCode 5
}
}
If I change the applicationId of flavor1 to 'com.myapp.android' I get this error:
Error:Execution failed for task ':app:processMainDebugGoogleServices'.
No matching client found for package name 'com.myapp.android'
So my question is, should I try to fix that error (and if yes how?) or is there any other work around ?

I haven't tried this, but reading the docs it seemd that just taking "applicationId" out of both flavor sections (main and flavor1) should work fine.

The new applicationId should be in your google-services.json as well.

Intellij - gradle refresh for android project that requires a parameter

I have gradle project, the simplified android part of the build.gradle of which looks like this:
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
minSdkVersion 15
targetSdkVersion 22
versionCode 1
versionName "1.0"
def mapPlacesApiKeys = [dev_1: [api_key: 'key_1', sender_id: 'sender_id_1'], dev_9: [api_key: 'key_2', sender_id: 'sender_id_2'],prod_1: [api_key: 'key_3', sender_id: 'sender_id_3']]
if (project.hasProperty('env')) {
if (mapPlacesApiKeys.get(env) == null) {
def keyset = mapPlacesApiKeys.keySet()
throw new StopExecutionException("Value '$env' is not a valid environment value. Valid environments: $keyset. You can set an environment by passing the -Penv=<env> parameter to your gradle build.")
}
}
buildConfigField "String", "SENDER_ID", "\"${mapPlacesApiKeys.get(env).get('sender_id')}\""
manifestPlaceholders = [maps_places_api_key: mapPlacesApiKeys.get(env).get('api_key')]
}
}
When I run this from the command line I run it with an environment parameter e.g. -Penv=dev_1. This does 2 things as you can see in the script:
a) Replaces in the androidmanifest the value "maps_places_api_key" with the actual key of the specified environment
b) Adds a String with the SENDER_ID in the BuildConfig java class.
This works fine from the command line. My problem is that in intellij (or android studio, should be the same) when I import the gradle project I get the following error:
-Penv is missing. You can set an environment by passing the -Penv=<env> parameter to your gradle build.
Which is the exception that I am declaring. So my question is how can I structure this code so that the IDE doesn't try to run it when it's loading the project.
Note that I don't want to replace the "env" parameter with any kinds of flavors or buildTypes, as there's about 15 different environments and it's gonna be a mess, but if there's another suggestion that comes in to your mind feel free to share it.

android{
defaultConfig {
applicationId 'com.xx'
minSdkVersion 14
}
productFlavors {
def path="./channel.txt"
file(path).eachLine { line->
def words = line.split(':')
def name = words[0]
def sender_id = words[1]
def api_key = words[2]
"$name" {
buildConfigField "String", "SENDER_ID", sender_id
manifestPlaceholders = [maps_places_api_key: api_key]
}
}
}
}

Change generated apk name from "app-debug.apk"

Every time I run a project with Android Studio (1.02) it's generate an unsigned apk which located in ..\build\outputs\apk folder and get by default the name "app-debug.apk"
I want to change that default name to something else.
Is it possible? How?

In build.gradle (Module: app):
android {
...
defaultConfig {
...
setProperty("archivesBaseName", "MyNewAppNameGoesHere")
}
}
This works by modifying the archivesBaseName-property and works for Gradle Version >= 2.0, last tested with 2.1.0.

You can use applicationVariants and change the output file in the build.gradle. You can also modify the name regarding to your needs.
buildTypes{
applicationVariants.all { variant ->
variant.outputs.each { output ->
output.outputFile = file("$project.buildDir/apk/test.apk")
}
}
}

Solution for gradle3:
android.applicationVariants.all { variant ->
variant.outputs.all {
outputFileName = applicationId;
outputFileName += "-v" + android.defaultConfig.versionName;
if (variant.buildType.name == "release") {
outputFileName += ".apk";
} else {
outputFileName += "-SNAPSHOT.apk";
}
}
}

defaultConfig {
applicationId "com.dcarl661.awesomelayout"
minSdkVersion 14
targetSdkVersion 25
versionCode 1
versionName "1.0"
//here put it in the section where you have the version stuff
setProperty("archivesBaseName", "AwesomeLayout")
}

defaultConfig {
applicationId "com.example"
def date = new Date();
def formattedDate = date.format('yyyy-MM-dd-HHmmss')
setProperty("archivesBaseName", "Quest_" + versionName + "_"+formattedDate)
}
i did like this. More detailed

If anyone is looking to change apk name outside the Android studio(just to send this file to someone else, as in my case), just right click the app name and change it to whatever you want.

The 'app' part of the name uses the folder name of your application's module (default is 'app'). See the link below on how to change that.
Why is my APK name generic?
The '-debug' prefix is something you can change in the Module settings at Build Types

Maybe this question (and its accepted answer) are interesting for you:
How to set versionName in APK filename using gradle?
It describes how to put your versionName into the APK name.
You have to use the 'Update' part of the accepted answer. Also you need the versionName (in this example) declared in your defaultConfig in the build.gradle file. It does also work if you define versionCode in the build.gradle (as described here: http://tools.android.com/tech-docs/new-build-system/user-guide#TOC-Manifest-entries ).

Android Studio 1.0 and error "Library projects cannot set applicationId"

After updating Android Studio to 1.0, I see this error:
Error: Library projects cannot set applicationId. applicationId is set
to 'com.super.app' in default config.
I updated the Gradle plugin as suggested but I did not understand how to fix this.

Based on this info:
ApplicationId in Library Projects
You cannot use applicationId to customize the package of a library project. The package name has to be fixed in library projects (and specified as packageName in the manifest). The Gradle plugin did not enforce this restriction earlier.
Removing applicationId variable from the library's build.gradle file should resolve the issue.

Thanks to Joel for his correct answer: I need to remove only 1 line from te .gradle file:
defaultConfig {
applicationId "com.super.app" <---- remove this line
minSdkVersion 15
targetSdkVersion 19
versionCode 1
versionName "1.0"
}
becomes
defaultConfig {
minSdkVersion 15
targetSdkVersion 19
versionCode 1
versionName "1.0"
}
and my AndroidManifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.super.app">
...
This is the right solution if you don't need to rename the package name of your app. To rename it you need to use "flavours":
android {
...
productFlavors {
flavor1 {
applicationId 'com.super.superapp'
}
}

Libraries can't set applicationId and if you are working in a multi-module project and picking up flavors from a separate file , none of the above answers will work. For a modularized app, you need the following steps -
Create a flavors.gradle file in project root directory
ext.flavorConfig = { // 1
flavorDimensions "pricing"
productFlavors {
free {
dimension "pricing"
ext.myApplicationIdSuffix = '.free' // 2
}
paid {
dimension "pricing"
ext.myApplicationIdSuffix = '.paid'
}
}
productFlavors.all { flavor -> // 3
if (flavor.hasProperty('myApplicationIdSuffix') && isApplicationProject()) {
flavor.applicationIdSuffix = flavor.myApplicationIdSuffix
}
}
}
def isApplicationProject() { // 4
return project.android.class.simpleName.startsWith('BaseAppModuleExtension')
}
In 1 we export a closure so that we can use it in our modules’ build.gradle files.
In 2 we define a custom myApplicationIdSuffix property. We cannot simply have applicationIdSuffix as it is not possible to use it in library modules (build would fail if you did).
In 3 we iterate over created flavors and set applicationIdSuffix if we detect that it’s an application module only.
4 is a way to check where this closure is being used.
All that’s left is to use this closure in our modules’ build.gradle files. E.g. in application module this would look like this:
apply plugin: 'com.android.application'
apply from: "${rootProject.projectDir}/flavors.gradle"
android {
// other config...
with flavorConfig
}
If this isn't clear, you can check out this article for better understanding.

Just incase it helps some one :
When i imported an eclipse project into android studio,i got an error ::
"Error:Application and test application id cannot be the same"
Strange though,but i looked into the build.gradle and found the two placeholders,one for the application and other for testapplication.
I removed the testApplicationId from that as is suggested in this post and this helped me resolve the issue.
Note: This explaination is not related to the errors posted in this question,but might help someone who is getting a similar error.

You cannot define applicationId for your lib.
But incase you want to use an identifier in your build file, which will give you, your library package name, you can define a variable for the module and then use the value as required.
eg : Library's build.gradle
apply plugin: 'com.android.library'
def libraryGroupId = 'com.google.example'
def libraryArtifactId = project.getName()
def libraryVersion = '1.1'
Also, you can use the value below as needed in your build file itself in lib.
android {
compileSdkVersion 28
defaultConfig {
minSdkVersion 21
targetSdkVersion 28
versionCode 1
versionName "$libraryVersion"
resValue "string", "Library", libraryGroupId"
}
}
