I want to use Flutter to create an Android app which depends on a third-party SDK that wrapped in an aar file. So far, I have only found the article Accessing Platform and Third-Party Services in Flutter. It seems that I have to build the Flutter project with additional Java files using Android Studio. This is complicated and not what I want.
Is there any way to directly load aar files or *.so files in Dart code? Something like how JNI works.
After learning the Flutter example - hello services, I have successfully built my Flutter project with aar file.
Basic Steps:
Download the Flutter source code.
Open flutter/examples/hello_services/android in Android Studio.
Click File > New > New Module and choose Import .JAR/.AAR Package.
Press F4 to open Project Structure, and then add the dependent module.
Write Java code to invoke APIs that defined in aar file.
Import flutter/examples/hello_services to Intellij IDEA.
Build and run the Flutter app.
I've pushed the source code to GitHub.
If you want to add .aar file to your Flutter project and faced problem in Android Studio saying
" can't understand Gradle settings file, please add the path ':moduleName' manually"
this tutorial is how to add Android .aar module to your flutter project manually.

I have an Android project for a library (using the com.android.library plugin), that includes C++ code. When I run the assemble task in gradle, the outputted AAR contains the native library in the /jni folder. However, there is no "prefab" folder. The only documentation I can find about creating Android libraries is here: https://developer.android.com/studio/projects/android-library
The bottom section suggests that the /prefab folder should be there.
I can find information on how to set up a project to import prefabs from an AAR, but I can't find any information on how to build an AAR with prefab exports. Is there a way to set up an Android project with gradle to do this? Are there settings I have to add to specify which native libraries should be exposed?
I'm using Android Studio 4.1.1, gradle 6.8, and Android gradle plugin 4.1.1.
This is covered by the samples. Not sure where it is in the docs, they definitely used to be on DAC. https://github.com/android/ndk-samples/tree/main/prefab/prefab-publishing
I am trying to import an android project created in eclipse into android studio. This main project also refers to another library project in the same eclipse workspace. The folder structure is like this:
workspace\app1
workspace\lib1
When I import the main project into android studio, the library project is automatically imported as a sub-project (or shall we call it a module) within the main project. That's not what I want. The library project is shared by multiple apps I am maintaining. It should sit in parallel with other app projects in terms of folder structure. I wouldn't want it to go understand any particular app project.
Please help explain how I can make the library project stand its own and refer to the library project from other app projects in android project. I am fairly new to the gradle build system. So detailed instructions would be highly appreciated. Thanks a lot!
Since you are importing in android studio, I assume you are moving to gradle build system. In your case , I think, it would be best to have a separate AS project for library. Use that project to generate a jar file and then import that jar using gradle build script in each project you want to use it.
If you are sharing the same library across multiple, you can configure them as separate AS project and have "aar" file as output. (In your gradle you put>> apply plugin: 'android-library'). You then define them as dependency in your gradle file. (either through maven repo or putting it in your libs directory and defining it in your dependencies section). You can find more info at http://tools.android.com/tech-docs/new-build-system/user-guide#TOC-Library-projects
You can use version control tool such as git to synchronize the library project in every main project. But you need to use a version control tool to manage all your projects first.
Read here on "AS Modules"
review 57.1.2 on "common behavior"
Take a look at a project built on AS pattern of modules as libs used in eclipse (gradle.settings) pictured
all the includes are modules
maybe you can rethink the idea of how to get AS to work for you in reusing code....
First of all I'm new to Gradle and I've a limited knowledge in it.
I've an android project. What I need is to integrate a Gradle library project with my project.
So my question is, IS it possible to add Gradle library project with an android Project without converting the android project to Gradle Project???
Can any one Help me to find the solution? I'm using eclipse as the tool.
Thanks in advance!!!
Yes. you can do it
Try these methods
Method1: Manually reconfigure your gradle based library project folder structure like your regular eclipse projects
Method2: Import project then Properties > java build path > source tab....remove path to src....add path to java folder in the source code using add folder button... then build your project as usual
Novice question.
What is the recommended way to run the sample apps, included in the Facebook SDK, in Android Studio (0.8.6)?
The ideal answer would include step-by-step instructions.
I'm using Android Studio version 0.8.0, and Facebook SDK 3.18.
When I tried to open a sample as a separate project, it can't find Gradle and wasn't able to run it. However, when I imported /samples folder as a root, all sample projects were imported and was able to run each samples.
File > Import Project > Select FACEBOOK_SDK_PATH/samples > OK > Create project from existing sources
and then, click next/ok as Android Studio's default setting.
Hope it helps!
Suposing you already downloaded and unzipped the SDK.
Create your android project. Gradle based.
File -> Import Module. Navigate to the unzipped folder and select the unzipped folder.
Add the library dependency in your main module (the one created with your project) adding this line in your build.gradle:
Synchonize project.
If you want to continue creating your own app, you might add the dependency module build.gradle file:
android {
dependencies {
compile project (':facebook')
}
}
I've done to create a phonegap 2.5.0 project template by following Getting Started with Android on Windows.
I'm using the ADT Bundle IDE from Get the Android SDK. After I setup new Android project from existing code, I get few errors that prevent building the project. I've solved AndroidManifest.xml, main.xml, strings.xml, config.xml. But I'm still getting the major error which is
Archive for required library: '~/libs/cordova-2.5.0.jar' in project 'xxx' cannot be read or is not a valid ZIP file
Does anyone facing this problem before?
To make things easy, you can create the project by using the command create provided with the phonegap package. Once created, you should be able to directly compile it without any errors.
To answwer your question, make sure you have cordova-2.5.0.jar in your libs. If not, add it using right click on project -> Build Path -> Add external archives. Then choose the jar.
