Android : Possible To Make A Free Demo Version Of Game To Be Used For Contest
Jul 21, 2009
I'm finishing to write my game and i'm thinking to participate to the ADC2. Since I also want to start selling the game to the android market asap, I want to know if is it possible to make a free demo version of the game to be used for the contest and a full paid version that is available to users that want to buy it before the contest has finished. Is it a violation of TOS or it can be done at my own risk (because the demo valued by judges is not the complete version?

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)

I want to release a demo version of my app. I added a restriction that the app could only be used 5 times by storing a counter in the db. However a user can easily uninstall and install the demo again! What the best way to manage this?

What is the recommended way of creating a demo version for an application. Basically, the demo version will be fully functional, but will be limited to running it 25 times. My worry is that if the user uninstalls and reinstalls, the count will be reset. I thought about writing a data file to the SD Card with the count of executions (hoping that would persist after uninstall), but I do not want to add that permission if I can avoid it. Any suggestions on how to have some type of demo flag persist after an uninstall?

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?

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?

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?

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?

I have pretty common question: is there any bug-free way to implement sound effects in a game?Or we only have unpredictable SoundPool with its horrible bugs? Or MediaPlayer that can only play one sound at once and which is not solution for a game at all?In fact, it is disturbing question for numerous developers right now!

How can I link my free android application to the "paid" version so a user of the free one can instantly click on the link and be taken to the android market page for the full version.

Angry Birds is free on Android, available now ? Cell Phones & Mobile Device Technology News & Updates | Geek.com didn't see this anywhere else in the fascinate forum. In this article it says that this offer crashed the server and that you can still get it free on getjar.com which is what I did. It works. Most popular mobile game ever made for free. Small ads in the bottom right corner that disappear after about ten seconds.

New to smartphones. Example: Just bought Picsay Pro. I see the free version is still on the phone. Can I delete it, or does the Pro version utilize and build on the free one? Another example is Documents to Go. OK to delete free versions after upgrading to pay versions?

I am releasing two versions of an app--free and paid. The differences between the two are few, and I would like to release both using the same codebase (maybe a different constant defined for the other build?). Has anyone done this? Can someone point me in the right direction?

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...

I just installed the new version of AdFree from the market and they finally got rid of the annoying bug that made it a pain to update (for those that don't know it blocks most ads in rooted android phones). Just a heads up to my fellow adventurers in Rootland...

I've been working on a new kind of math puzzle game only for Android. Try it out and tell me what you think! NumNom (Free!) - Android app on AppBrain. The game is all about making sets of numbers that add up to "the target" (changes depending on the game # -- like freecell). I suck at any kind of graphic design, so sorry there are no "magical sparkly's"! I still think the game is really fun, and most of my friends (who are cool enough to use Android) seem to love it.Let me know what you think! I'd love to hear real feedback from people I don't already know. Oh, and if you have questions about Android development or selling apps on the market, ask away.

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?

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.

I have been developing an Android game in the evenings for the past 6 weeks or so. It has finally got to the point where I am happy putting it on the market.. It would be great to get some downloads and feedback! The game is similar to match-3 style games with a hint of pacman and tetris There are now two game modes in the game, 'classic' and 'drop'. In the first your aim is to stop the timer going down by popping and eating fish. In drop, fish fall from the top and you must keep eating to stop the screen from filling! You can check it out (video etc) at.

CREDIT TO GOODANDEVO.NET. u'll be redirected to the EVO-optimized site where you'll see a limited offer to get Let's Golf at no cost if you download the company's HD games bookmark, which can be uninstalled with no consequence after you get the game. As with all of Gameloft's HD games, Let's Golf usually costs a penny shy of . The game can't be transferred to another device or reinstalled (even if it's backed up), so don't uninstall it or do a hard reset unless you want to contact Gameloft to see if you can get it again.It isn't clear how much longer the free game will be available, so get it now! o download go to the gameloft.com site on your evo using ou default browser.

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?
