Android :: How To Factor Code For Free / Paid App Versions?

Jan 19, 2010

I have a project which I want to split into a paid and a free version. I do not care to double my management of the res/ folder and would even like the Android Manifest.xml to be the same file except for the package line. Worrying little about hacking (at this stage - my app is not copy protected anyhow so other avenues of vulnerability are already open), it might be sufficient for me to have all the logic in the free app, and to enable/disable functions based on the app's own package info. What strategies have others used in this regard? I have soft-linked the source from a new Android Eclipse project folder tree to the existing one (the new is to become the paid version and the old one will become the free one with some logic paths being conditionally stubbed at runtime), reserving the new source file hierarchy in the new one to the sole purpose of containing an My Main Activity.java file (as it will need to be in a different package- folder than the one for the free app's). But the res folder appears as though it might be more difficult.

Android :: Split App - Eg Free - Pro Versions Using 95% The Same Code

Mar 11, 2010

I have a free app out there and am going to write a pro version with some extra functionality that I'll charge for.

The plan is to use the same code for both apps, although I need different Eclipse projects to use different manfiest files. The obvious way is to have all my code in a shared library which the free and pro projects reference.

Android :: Maintaining Both Free And Pro Versions Of Application

Mar 27, 2010

I want to create a PRO version of my application for Android and was wondering how to structure my repository. For know I have a trunk and feature branches. I'd like to put a pro version in another branch but maybe there is a better way? For example, maybe I should create two branches - one for free version, the other for pro?

Pro version will have additional features and will be ads-free, so e.g. I don't want to include AdMob libraries in the pro version. Do you have any experience or suggestions as to what would be the best way to structure the repository in this case? I think I've found the best solution (for my app) in this thread:
http://groups.google.com/group/android-developers/browse_thread/thread/4ad3d67f735f16d7/948b4f9eee2490a3

The trick discussed there is about having another application that only serves the purpose of unlocking PRO functionality in the actual application. The unlocking app is paid in the market and the actual app merely checks for the existence of it on the device.

Android : Implement Free Versions Of Applications?

Dec 31, 2009

I already mentioned this briefly in another post as part of another publishing topic.

But I think it is pretty important for a lot of us to know good ways to make free versions that can't be cracked too easily etc. After all most people just download the free stuff, I know I do, so its important for numbers.

I just made a game called ScrollSlider and I want to make a free version with limited evaluation period perhaps, but I could use some advice on how to do it. I'm also having problems with data persistence as views appear and disappear and managing game loop view thread accordingly.

Android :: How To Convert Free App To Paid App?

Mar 4, 2009

From what I learn, a developer cannot convert his FREE app to a PAID app. I was looking out for some alternative ways to make this happen. I have an app with about 10K users. Users have their data stored inside the application. Lets call the existing FREE version com.my app I would like to sell my app for $10. How do I go about it? If I create a new application, it does not accept com.my app since it says I already have an app on the store with the same name. Create a new app: com.paid my app does not help because how do the existing 10K users get their data from FREE version (my app) to PAID version (paid my app)

Android :: How To Release Paid Upgrade For Free App?

Oct 28, 2010

Is there a way to change free app into paid app in Market? I.e. you release com.foo.xxx as free but later you'd like to charge for app and drop free version completely.. I do not see anything like this in Market console at the moment. I know I can release com.foo.xxx.pro for example but my intention would be to keep package name as is so current users would see there's upgrade available. Alternatively, if there's no way to do that can I completely remove app from market so com. would be reusable for other app?

Android :: How To Import Data From Free App Db To Paid App Db?

Feb 8, 2010

I currently have a free application on the market and I'd like to offer a paid version of it as well. Once the paid version is installed, I want to import the db and shared preferences from the free version so users can un install it without losing anything. The problem is this: in my free version, I don't have a android:shared UserId set. If I add one, the app's id on the system changes and I can't access the data anymore. Both apps will be signed using the same certificate. How can I import the data without messing up the permissions of the free app?

Android :: Free And Paid Version For Share Data

Jun 5, 2010

I have a free app in the market and use the data directory of the app to store some files. Now I think about offering a paid (donate) version of the app, so that people who want to pay a few pennys will be able to do so. But AFAIK the new (paid) app needs a new name, so I won't be able to use the stored data of the free version. That means, that existing users would have to re-enter a lot of personal settings - which probably would be a no-no for a lot of users. So my question: Is there a smart way to have a free and a paid version in the market, where the later installed payed version can use the data of the free version? I thought about using the SD-card for data storage, but there might be devices without any SD-card...

Android :: How Licensing Work In Transitioning From Free App To Paid?

Feb 11, 2009

Here's the scenario: The app is on the market for free. The publisher then decides to make it a pay app and changes the status. I'm assuming you can just do that, but my questions are:
1) Will the publishing console require us to upload a new version if it is to be a pay app, or can we just change it on-the-fly? 2) If we can change it on-the-fly, how will that affect users that have downloaded the free version? Do they get the license to the paid one as well (so they can delete but reinstall the app for free, get updates, etc?) I've finished a game but I've been just waiting for the paid apps to come on line before publishing it. I'm now thinking that I wouldn't mind a 1 week free period before going paid but something felt like the users who download it for free would never have to pay even after I change it to paid and add some sort of desirable update that makes them want to download the new version (and pay then to get it if they have to).

Android :: Share A Database Between A Free And Paid Version Of An Application

Oct 2, 2009

I have an application for which I am planning to release both a free and a paid version. I found that this will require the two versions of the application to each have different package names.

When a user upgrades from the free version to the paid version, the paid version needs to be able to access the database built by the free version. I am trying to understand the best way to make sure that upgrade does not disrupt the user's data.

I have read that the AndroidManifest file setting for shared user id should allow both applications to access the same data. I don't need the applications to both be running simultaneously, as I expect the user will uninstall the free version after upgrading to the paid version. However I need to make sure that if possible the user's data is not lost and is still accessible and usable by the paid version of the application.

I have read about a problem with the shared user id where uninstalling one application will cause the other shared application to stop working because its permissions get deleted, (see details at http://code.google.com/p/android/issues/detail?id=2773 ) Apparently this issue is fixed in doughnut, but since all the currently deployed android phones do not have doughnut yet, this still seems like a significant problem.

In addition to the database information, I would also like to preserve the user's default shared preferences settings after the upgrade. However the default shared preference settings are not as critical as the data in the database.

Android :: How To Handle Application Upgrades From Free To Paid Version / While Preserving Any Data

Jun 10, 2010

I want to have a free version and a premium version of the same application. When people buy the application, I want them to be able to "upgrade" without losing their data, i.e. the premium version should install over the free version.I want to use the same code base and just switch a setting to build the premium version.
Andoid Market does not let me convert a free app to a paid app, so the trivial option is not available.I am curious if someone has tried this successfully. How does Android Market identify an application - will it think that the premium version is a different app and just install it in parallel?
