Android :: How To Use Paid Version Of App As A "key" To Free Version?

Jun 17, 2010

Let's say for example that I have some Android app that does X. The free version has ads or basic features. I want to have a paid version that removes the ads and adds extra features. How can I use the paid app as a "license key" to unlock the features in the free app? So the user would install the free app, then install the paid app to get the extra features, but they would still run the free app (which would now be unlocked). What's the best approach to doing this?

Android :: Maintaining A Free And Paid Version & Maybe Other Version

Apr 5, 2010

I used to be a C/C++ programmer before getting in to android. I am not sure how people maintain 2 versions of a program without using #ifdef preprocessor macros. Right now I am changing the package name in eclipse and changing the code manually, but this seems really inefficient. Can anybody suggest a good way of having 2 or more projects that share most of the code?

Android :: What's Difference Between Free Version And Paid Version?

May 25, 2010

I'm planning on getting LockBot when I get my EVO and I was wondering, what's the difference between the free version and paid version. I basically want the Moto Droid lock screen on my EVO for the slide to toggle sound on/off feature due to the lack of an external switch on the EVO. Would I be best to get the paid version or will the free version do that?

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 :: 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?

Games :: Just Released Word Warz Game Free/Paid Version

Oct 3, 2010

I just released Word Warz yesterday on the android market. Still looking for some valuable feedback! Tell me what your think about my first application.

Game Description:
Word Warz is a competitive spelling game. In the game players take turns adding letters to a board to spell a word. However, you don't want to be the last person to spell the word, because you will be out of the round. The strategy in the game centers around picking the letters at critical points that will force other players to spell a word. Also, a player can bluff by adding a letters that don't spell a word, and risk being called out by the next player. If a player calls a bluff, and the previous player was bluffing they are removed from the round. If the previous player wasn't bluffing the player that called the bluff is removed from the round. The last man standing during each round receives a point. The first player to 7 points wins the game.

Right now the game supports four offline human players, and 3 different computer players. The demo supports 2 players(either 2 human players or a human player versus chubs(the easy computer player)

Android :: Releasing Demo Application From Paid Version - Fork Code?

Jun 4, 2009

We have a paid app in the market place, we would like to release a demo of the paid app. I was hoping we could just recompile w/ the same package name, but apparently that does not work. I have tried manually changing package name etc, but it is a chore, and it seems that several things that automatically happen in eclipse cause more harm than good when renaming the package name. Which brings me to my next question. If having a new package name is the only way to accomplish this. Is there an easy way to fork the paid app, where keeping the changes synchronized is easier? Some kind of Source Control?

Android :: Way To Give Out A Device Specific License Free Version?

Jul 27, 2010

I just finished reading the docs on Google's new Android License Verification Library. I often give out free copies of my applications to beta testers. I don't, however, want the beta testers to share the app with their friends. What's the best way to give out a device-specific license free version? From what I can tell I will need to create a custom policy and then maintain a list of authorized devices/accounts in my own backend that I can check. Is that what other devs are doing?
