Create an aar with all flutter libraries and dependencies inside

I need to create an aar with all the libraries of my flutter project inside, I created a flutter module and now I've to create an sdk in android to be embedded in a client app for that it would be nice to have a single aar file. I tried Mobbeel fat AAR Gradle plugin but with no avail. I know I can create a maven repository but that is not the solution I'm looking for right now.
my project build.gradle
buildscript {
repositories {
maven { url "https://plugins.gradle.org/m2/" }
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.1'
classpath "com.mobbeel.plugin:fat-aar:2.0.1"
}
}
allprojects {
repositories {
google()
jcenter()
}
}
and the app build.graddle
def flutterPluginVersion = 'managed'
apply plugin: 'com.android.library'
apply plugin: "com.mobbeel.plugin"
android {
compileSdkVersion 28
compileOptions {
sourceCompatibility 1.8
targetCompatibility 1.8
}
defaultConfig {
minSdkVersion 21
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
buildDir = new File(rootProject.projectDir, "../build/host")
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
api (project(':flutter'))
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation 'androidx.annotation:annotation:1.1.0'
implementation 'androidx.lifecycle:lifecycle-common:2.0.0'
}
aarPlugin {
includeAllInnerDependencies false
packagesToInclude = ["mobbeel"]
}
EDIT: I found a solution, but I'm not an android developer so a made some changes to the mobbeel plugin and add it to the build.gradle. After that I was able to add all the libraries to my aar by doing api project(":vibrate")

Add Android native library into your project in Android Studio: File -> New -> New module -> Android Library.
After that add this plugin https://github.com/kezong/fat-aar-android into the project and replace 'implementation' by 'embed' keyword.
Then your project structure will look like:
In flutter_library directory run command flutter build aar -v. Note: flutter_library contains Flutter related files, e.g lib/, .android, .ios, pubspec.yaml, etc
In root project directory run ./gradlew assemble
aar will be located in library/build/outputs/aar
See my example: https://github.com/askarsyzdykov/native_flutter_lib

The aar file doesn't contain the transitive dependencies and doesn't have a pom file which describes the dependencies used by the library.
It means that, if you are importing a aar file using a flatDir repo you have to specify the dependencies also in your project.
I know that it is not the solution you are looking for but you should use a maven repository to solve this issue.
In this case, gradle downloads the dependencies using the pom file which will contains the dependencies list.

Android gradle change resources on merge

I have a json config file and I put it in res/raw folder. previously I have a gradle script that updates the file contents when it was necessary.
def fetchMeta(buildVariant) {
def flavor = buildVariant.productFlavors.get(0).name
def buildType = buildVariant.buildType.name
def middleMetaFolder = "${buildDir}/intermediates/meta/${flavor}"
def pathToMiddleMeta = "${middleMetaFolder}/latest.json"
def rawFolder = "${buildDir}/intermediates/res/merged/${buildVariant.dirName}/raw/"
def f = new File(pathToMiddleMeta)
boolean doDownload = (!f.exists()) || (f.lastModified() < (System.currentTimeMillis() - 86400000))
// Force on production release
if (doDownload || (flavor == "production" && buildType == "release")) {
new File(middleMetaFolder).mkdirs()
def serverAddress = "https://example.com"
String srcUrl = serverAddress + "/latest.json"
println "Downloading Meta from: " + srcUrl + " to " + pathToMiddleMeta
new URL(srcUrl).withInputStream { i -> f.withOutputStream { it << i } }
} else {
println "Skipping Meta as it exists here: " + pathToMiddleMeta
}
copy {
from pathToMiddleMeta
into rawFolder
}
}
android.applicationVariants.all { variant ->
variant.mergeResources.doLast {
fetchMeta(variant)
}
}
But as of android gradle plugin 3.0 merge strategy changed and files are with flat extension. How can I update the contents of my file after these changes?

had the same issue, which comes with the update from aapt to aapt2
issue is already assigned at google issue-tracker
https://issuetracker.google.com/issues/65220623
as a workaround right now you can set android.enableAapt2=false in your gradle.properties

Gradle, task to copy mapping file

It's necessary to have mapping.txt file to check crashes come from your app (because of ProGuard), in many cases developers forget to copy mapping file and back it up and after next release it will be changed and useless to check previous version bugs.
how to copy mapping file after release and copy version as suffix to it's name in particular path using gradle task automatically?

This is the snippet I use. It does depend on having a productFlavor defined but that is only to help name the file and allow the same snippet to be reused in multiple projects without modification but that dependency could be refactored out if you wanted a different filename format.
As it stands, the apk and the mapping file (if required) will be copied to the defined basePath in the format:
FilePath\appname\appname buildtype versionname (versioncode)
e.g
A:\Common\Apk\MyAppName\MyAppName release 1.0 (1).apk
and
A:\Common\Apk\MyAppName\MyAppName release 1.0 (1).mapping
Amend as you see fit.
android {
productFlavors {
MyAppName {
}
}
//region [ Copy APK and Proguard mapping file to archive location ]
def basePath = "A:\\Common\\Apk\\"
applicationVariants.all { variant ->
variant.outputs.each { output ->
// Ensure the output folder exists
def outputPathName = basePath + variant.productFlavors[0].name
def outputFolder = new File(outputPathName)
if (!outputFolder.exists()) {
outputFolder.mkdirs()
}
// set the base filename
def newName = variant.productFlavors[0].name + " " + variant.buildType.name + " " + defaultConfig.versionName + " (" + defaultConfig.versionCode + ")"
// The location that the mapping file will be copied to
def mappingPath = outputPathName + "\\" + newName + ".mapping"
// delete any existing mapping file
if (file(mappingPath).exists()) {
delete mappingPath
}
// Copy the mapping file if Proguard is turned on for this build
if (variant.getBuildType().isMinifyEnabled()) {
variant.assemble.doLast {
copy {
from variant.mappingFile
into output.outputFile.parent
rename { String fileName ->
newName + ".mapping"
}
}
}
}
// Set the filename and path that the apk will be created at
if (output.outputFile != null && output.outputFile.name.endsWith('.apk')) {
def path = outputPathName + "\\" + newName + ".apk"
if (file(path).exists()) {
delete path
}
output.outputFile = new File(path)
}
}
}
//endregion
}

Android: add date/time to gradle output apk filename

How to add date/time stamp to Gradle Android output file name?
Should be like project_v0.5.0_201503110212_public.apk
Already looked at
how append date build to versionNameSuffix on gradle
How to pass arguments from command line to gradle

I'm assuming that you want it in the format you specified, so here's one possible solution.
In your gradle file you can define a new function to get the date time string like you desire:
import java.text.DateFormat
import java.text.SimpleDateFormat
def getDateTime() {
DateFormat df = new SimpleDateFormat("yyyyMMddHHmm");
return df.format(new Date());
}
Then for all variants you can simply run this:
android {
//...
buildTypes {
//...
android.applicationVariants.all { variant ->
variant.outputs.each { output ->
def file = output.outputFile
output.outputFile = new File(file.parent, file.name.replace(".apk", "-" + getDateTime() + ".apk"))
}
}
}
}
Note that this doesn't really output the apk name like you posted, but I guess it's enough to help you out.

This code working for me.
applicationVariants.all { variant ->
variant.outputs.each { output ->
def project = "Your App Name"
def SEP = "_"
def flavor = variant.productFlavors[0].name
def buildType = variant.variantData.variantConfiguration.buildType.name
def version = variant.versionName
def date = new Date();
def formattedDate = date.format('ddMMyy_HHmm')
def newApkName = project + SEP + flavor + SEP + buildType + SEP + version + SEP + formattedDate + ".apk"
output.outputFile = new File(output.outputFile.parent, newApkName)
}
}

I also add a formatted date to my build. In first place I used some kind of "now" with new Date(), but this leads to trouble when starting the build with Android Studio, like in one of the comments above. I decided to use the timestamp of the latest commit. I found some inspiration here: https://jdpgrailsdev.github.io/blog/2014/10/14/spring_boot_gradle_git_info.html
Adding the timestamp is handled like below:
def getLatestCommitTimeStamp() {
def revision = 'git rev-list --max-count 1 --timestamp HEAD'.execute().text.trim()
def gitCommitMillis = java.util.concurrent.TimeUnit.SECONDS.toMillis(revision.split(' ').first() as long)
return new Date(gitCommitMillis).format("_HH.mm.ss_dd-MM-yyyy", TimeZone.getTimeZone('Europe/Berlin'))
}
My renaming part looks like this:
android.applicationVariants.all { variant ->
if (variant.buildType.name == 'release') {
def lastCommitFormattedDate = getLatestCommitTimeStamp()
variant.outputs.each { output ->
def alignedOutputFile = output.outputFile
def unalignedOutputFile = output.packageApplication.outputFile
// Customise APK filenames (to include build version)
if (variant.buildType.zipAlignEnabled) {
// normal APK
output.outputFile = new File(alignedOutputFile.parent, alignedOutputFile.name.replace(".apk", "-v" + defaultConfig.versionName + "-" + variant.buildType.name.toUpperCase() + "-${gitSha}" + lastCommitFormattedDate + ".apk").replace("-" + variant.buildType.name, "").replace(project.name, "otherName"))
}
// 'unaligned' APK
output.packageApplication.outputFile = new File(unalignedOutputFile.parent, unalignedOutputFile.name.replace(".apk", "-v" + defaultConfig.versionName + "-" + variant.buildType.name.toUpperCase() + "-${gitSha}" + lastCommitFormattedDate + ".apk").replace("-" + variant.buildType.name, "").replace(project.name, "otherName"))
}
}

An alternative solution is to set $dateTime property in defaultConfig as shown below:
defaultConfig {
setProperty("archivesBaseName", "Appname-$dateTime-v$versionName")
}

This is mine hope to help you
android.applicationVariants.all { variant ->
variant.outputs.each { output ->
def file = output.outputFile
output.outputFile = new File(
(String) file.parent,
(String) file.name.replace(
file.name,
// alter this string to change output file name
"APigLive_Android_" + variant.name + "_" + variant.versionName + "_" + releaseTime() + ".apk"
)
)
}
}
def releaseTime(){
return new Date().format("MM:dd:HH:mm", TimeZone.getTimeZone("GMT"))
}

You can just add the code below inside the defaultConfig section located in android section.
setProperty("archivesBaseName", "yourData-$versionName " + (new Date().format("HH-mm-ss")))

Access a path from .bashrc in gradle.build on a macbook pro

I have a set a path in my .bashrc which I wanna have access to from my build.gradle file.
I'm using the commandLine method in gradle, but I can't seems to get it working.
My .bashrc:

In my gradle.build file I have the following code:
def getOutputPath = { ->
def stdout = new ByteArrayOutputStream()
exec {
commandLine 'echo', '$APK_PATH'
standardOutput = stdout
}
return stdout.toString().trim()
}
applicationVariants.all { variant ->
def newName;
def versionNumber = variant.versionName;
def appName = variant.name.replace("Release","");
def date = getDate();
if (variant.buildType.name == "release") {
newName = appName + "_" + date + ".apk";
releaseDir = getOutputPath() + "/" + appName;
} else {
newName = variant.name;
}
variant.outputFile = new File(releaseDir, newName);
}
When i'm trying to make a release build I get the following error:
Unable to open '$APK_PATH/ostran/ostran_20141209.apk' as zip archive

Instead of using the .bashrc file you can use your local gradle.properties which I found WAAAY easier!
You can place a gradle.properties file in the Gradle user home directory. The properties set in a gradle.properties file can be accessed via the project object. The properties file in the user's home directory has precedence over property files in the project directories.
If this property does not exist, an exception will be thrown and the build will fail. If your build script relies on optional properties the user might set, perhaps in a gradle.properties file, you need to check for existence before you access them. You can do this by using the method hasProperty('propertyName') which returns true or false.
my flavors.gradle
applicationVariants.all { variant ->
if (project.hasProperty('APK_PATH')) {
def appName = variant.name.replace("Release", "");
def releaseDir = variant.outputFile.parent
def newName = variant.name;
if (variant.buildType.name == "release") {
newName = appName + "_" + getDate() + ".apk";
releaseDir = APK_PATH + appName;
}
variant.outputFile = new File(releaseDir, newName);
}
}
