Is it possible to have 2 projects in 1 android? - android

I need to make one project of 2 projects. I had copied all files from 1 to other, there was no problem. But the problem is generating R file as there a different packages.
Maybe i can some how make manifest of 2 projects that there would be both projects packages.
Please correct me if on my question as i don't know how to ask this. Basically i want to make 2 manifest in one.
Thanks.

Convert one of your project into Android Library and use that library in your second project to merge it together as one single project.
For more info, refer to refer to android's TicTacToe sample project

I am not sure, maybe you have to change the package name of two projects to the same one, then clear your project and then you will get just one R.java
There are something you have to pay attention. The package name in two "AndroidManifest.xml" file also need to be change. And you maybe want to merger two "AndroidManifest.xml" file into one and just let one of activity as MAIN.
Good luck.

Merge all Android project classes in one file with the Android Studio

I have maybe strange question, but would be appreciate if someone helps.
I need to merge all the code from classes ( which are part of the packages ) in one text or class file for Android project in Android Studio.
So I have for example such a structure
And I need to merge the code from NewAlbumDialog, MenuAdapter, MenuItem etc classes in one big file.
Maybe somebody know how can I do it with the Android Studio.
Would be appreciate your help.
I don't think there is a tool for this. Just use a text editor.
However be aware that a Java file is not valid as soon as it includes more than one public class - see Multiple classes in single file

How to Use Ant Script replace strings, switch resources folders, auto generate R.java and compile final Apk?

We hope to build multiple applications based on the same source code. The base source code will be stored in SVN so at daily development we just need to modify one codebase.
While for different customers, we hope to given some some level of branding. Mostly changing images and titles, these can be done by just change the resources.
After some research, We find that it is really touch to do these multiple version applications. The main problem is that R.java is generated based on the package name. And package name identify the application. In the source code there are many files import this package.name.R, which means for different application, there will be different package name, and different R's reference need to be change in most source code file.
We find some articles on web about using Ant to do this task, but none of them are really specified. We hope someone could help!
Generally the workflow will be like this:
Changing the package name in AndroidManifest.xml
Go over all source code file, find and replace anything referenced to R to the new package name.
Switch the res folder to the new client's res folder (We will have this folder ready)
Auto generate R.java file.
Start normal compile and build process.
Get Apk.
We hope someone could point out how can we achieve these task by using Ant, or any other better solution.
Thank you!
I think you should create an Android Library Project (http://developer.android.com/tools/projects/index.html#LibraryProjects) with the common code, check it into VCS, and then create separate projects for every customer which you should also check into VCS to keep track of them.
You will be able to generate different customized versions from same source code.

Android Multiple APK from same code base

My goal is to create multiple android APKs. All that is different is the package name and I manually override some things in the res folder.
I understand you can do a library project. The problem with that is we have to manage multiple manifest files and the version with that. That is not what I want to do.
I was looking into aapt to create the new package name and shared res folder. The problem is I do not know where to start. I see lots of examples like:
Custom Android build.xml for rename manifest package
also below is exactly what I want to do:
http://blog.uncommons.org/2010/07/19/building-two-versions-of-the-same-android-app/
Can anyone provide direction on where to start?
The best way to do this is to create a library project, and than create separate projects for each of the APKs that you want to have. Each APK project can than have its own Manifest and reference the Library Project. Believe me when I tell you that this is much easier than trying to rename packages during build/compile time. You can easily call into activities that are shared in the library package just as long as you use the fully qualified name in the individual APK's manifest file.

I had the same problem before and made a batch file to copy files like images, mp3 files, etc. to the workspace folder where I have my application folder in it. You have to make everything dynamic if you don't want to use the library project. I hope this helps, else you can ask me anything you want.

Creating a project to be reused

I'm sure you can help such a newbie like I am.
I created a project in android and I want to use it as a model for next 10 and more apps, just changing the raw sources.
I mean I want to make some products i.e. 10 videocharts about norway, I make one project with the needed activity and resources so each app will differ only for the content value.
I will keep of course the same file name too if needed.
How can I save the project?
Cause I tried to make a new project from resource but I get an error on top of the tab saying Manifest is not present in the folder while manifest is actually there, and I cannot proceed further.
Thank you

This sounds like a place to use an Android library project.

How to distribute the android reusable code in a package?

I have developed some reusable android component which is basically a class . This class has some resource dependencies e.g. some png drawables, some xml layouts etc. So this class referenced the auto-generated R file.I would like to distribute this code in a single package like jar file to other developers for use in their applications.
I have read that the only possible solution is to distribute code together with all my resources, which others have to copy to their "res" folder (source).
So I created a jar file having the class file (say MyClass which is in the package com.xyz.android.app) and resources and tried to use this in my new application.
So I added the jar file to my new applications build path using add external jars option in eclipse and copied all the resources to my new application's res folder. (The activity class say MainActivity of my new application is in com.abc.myapplication package, just for the case if it may helpful)
But when I run this new application there is java.lang.ClassCastException in the MyClass class. I tried to debug the application and then I found that in the MyClass class, there is "R cannot be resolved" problem.
Then I changed MainActivity's package to com.xyz.android.app (which is not the way, other developers will be happy to do), But again the same problem.
But When I just copy the source java file such that both MainActivity.java and MyClass.java are in com.xyz.android.app package then application runs fine.
So if I need to distribute such that other users need not to bother these package naming things,
how can I accomplish this? Please help !!
Edit
In android.jar, there are also some resources. How are they referenced in a project? How are they used in android classes? There is also android.R file?
Is it not possible to do the same thing i.e. to make jar file like android.jar for my reusable code?
As Nic Strong noted, there is nothing much built into the project to manage this, and current indications are that the upcoming changes to the SDK tools may only help a bit.
I am organizing some other tools to help deal with this problem. I hope to have developer documentation published in a few days.
This is not so easy to do at the moment. The problem is the project using your jar does not know to look in there for drawables etc.
The good news is it should soon be possible (hopefully with SDK 2.2 which is rumoured to be released at IO next week). See this blog post http://mobilebytes.wordpress.com/2010/04/27/android-tools-version6-coming/
I've been playing with Mark Murphy's ParcelHelper class at http://github.com/commonsguy/cwac-parcel. In a nutshell, it's a collection of methods that let you access the components of 'R' by name without needing to import 'R' into your code.
If I understand your question right, this is exactly what you want. You may still need to copy some resources, such as styleables, into your project.
