FreeBuilder library in Android Studio project - android-studio

I'm trying to use FreeBuilder library. It is a library for the implementation of the Builder design pattern. When I build the project no error are shown and the project is build successfully, but I connot run it because of some errors on generated files. Android studio, however, doesn't recognize generated builder and the methods of the builder. I'm trying the example on the README of the library page.

Create Kotlin Library

I am trying to achieve what is extremely simply in other languages, however I am new to Kotlin and Android Studio.
I wish, when creating a project, to reuse code by having it in a seperate directory to the project, but to be able to create instances of a Kotlin class in a given project, and also to be able to edit the class definitions and rebuild the 'library' in that open project
Before anyone shoots me I have read
Create a Kotlin library in Android Studio
this however does not work and simply results in

how to add library to android studio not the single project

I want to add library to my android studio, the only way that i know is through the gradle.build file like:
implementation 'com.android.volley:volley:1.1.1'
the problem here is that the volley library is added to the current project only, and if i created an new project i will have to write this line of code again and sync project, is there's any way to add the library to android studio itself so that any time i open new project i have no need to write this line of code and sync project?
You need to create one common build file where you put all library dependencies and common dependencies build file is used app build file or other build file as apply plugin.
Ex: apply plugin: 'common_build.gradle'

Incorporate 3rd Party Native Libs into Android Studio project

I am trying to setup an NDK library module structured very similar to the gen-libs module in the Android-NDK sample project. It identifies what I want in an Android NDK library module to allow me to incorporate 3rd party Native Libs:
src/main/cpp
CMakeLists.txt
Android manifest
build.gradle
I am NOT looking to add C or C++ source files to my app module.
Instead, I am looking to create an Android-NDK library module within Android Studio, so that I can incorporate 3rd Party Native Libs.
However, I am Unable to easily reproduce the structure of the gen-libs module in Android-NDK sample hello-libs.
More specifically, Android Studio does not provide any option to create a "New => Module => Android Library => Add NDK/C++ support"
I suppose I can recreate this NDK module manually, but before I do that, I would like to ask the community if, for a brand new project, is there any easy way to auto-create the gen-libs module structure from hello-libs beside manual method?
Feel free to use your copy/paste skills to produce the project manually. The wizard won't do it for you, at least for now.
You can also create an app project and switch it to library by changing one line in build.gradle.
You can also create a library module, right click on this module, and choose 'Link C++ Project with Gradle' from the popup menu (or from File menu).

Building tess-two into a project using Android Studio's gradle build

There are answers about getting the tess-two project integrated into an Android project within Android Studio, but many are out-dated and none used the current capabilities defined here:
Using Android Studio 2.2 and higher, you can use the NDK to compile C and C++ code into a native library and package it into your APK using Gradle, the IDE's integrated build system. Your Java code can then call functions in your native library through the Java Native Interface (JNI)
What specific steps would be required to make tess-two functionality a part of the resulting APK, using functionality within Android Studio, rather than external file placement, manipulation and command line tools? So taking the building, creation of *.so files into the IDE. Specifically using just Android Studio's integrated build system (Gradle) as described here.
1. Start a new project
2. Import Tess-Two into the project
2b. Add any needed plug-ins
3. Add code in the main activity to get native functionality
4. Configure Android Studio build so that native functionality is available
This is where the specifics are required
4. Configure Android Studio build for native functionality
4a. Link C++ Project with Gradle
First, check the tess-two project for build files. You may select CMakeLists.txt or Android.mk files. Both are currently supported.
In this case, I used ndk-build, which seemed like a good bet for integrating the native code.
For more information, see Android Studio documentation
4b. Manage Long Commands
In Windows, errors may be encountered if the command length grows too large. To prevent problems, use LOCAL_SHORT_COMMANDS AND APP_SHORT_COMMANDS in the Android.mk file.
The "e=87" error is what you are avoiding by doing this:
For more on that topic, see stackoverflow question about error 87.
4c. Add Module Dependency for tess-two
In File > Project Structure > Dependencies use the + to add the tess-two dependency:
4d. Build the Project and check .apk file for .so files
The build, which takes a long time, should complete now. Validate that the .apk file contains the .so files, created during the build. With the tess-two libraries in an static initializer, run the project on your Android device:

Sharing own module across projects Android Studio

I'm struggling badly with moving from Eclipse to Android Studio.
Basically, I get that an Android Studio project is more like a workspace and a module more like a project...
However, in the Android Studio start page you can only create projects, so how do you share a module (i.e. a project in eclipse terms) across projects?
Basically, I have a number of apps that use a shared library I've created, in Eclipse all I do is flag it as a library and in each project simply link to it.
I have absolutely no idea how to do this in Android Studio. The examples for creating modules seem to take you as far as creating a module for no real purpose other than to use it within one app.
I first imported my library as a project in android studio, but that proved pointless, thinking that was how to do it because I want it kept separate in my version control system.
I then created a temporary module inside my app, but then it stores it within the project and in my other apps I cannot find a way to import the modules, so I really don't see what the point of a module is when it's embedded in a project and can't be separated or referenced anywhere else.
Thanks for any help.
Consider your library project name common-lib
Open build.gradle of the projects to which you want to add library add add the following
dependencies {
compile project(':common-lib')
}
and sync gradle
