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?

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 :: Non Free Open Source License For Android Application?

Nov 7, 2010

I'm working on an Android App, and I want to provide a free demo and a paid full-version from the Android Market. However, I also want to provide the source code. I don't mind if people want to play with the code and install modified versions on their own devices. However, I don't want to see any free full-version binaries on the web, and a license like the GPL would allow anyone to offer some, probably even making profit that way.

If some people would rather build and deploy the app themselves instead of paying 1-5$, they can go ahead. But a convenient one-click-download button and other people making money from my efforts is not what I want. Is there any pre-existing license I can use for something like that? Furthermore, if I want to start an app as free and open source, but later decide that I want to make money from selling it, is there a FOSS license that allows me to move to the license I'm asking about above later?

Android :: Load Specific Lines Of Code According To OS Version?

Aug 23, 2010

Is there a simple line of code that would allow only loading the code if the OS version meets the requirements? Lets say I have my target OS as 2.2 but the min sdk is 3 for android 1.5 so even if i have some code in my project that isn't compatable with 1.5 it will still compile since the target OS is 2.2. Anyway, I want to ad a feature that requires code that's not in the 1.5 SDK and will cause a crash if it's loaded on a 1.5 phone. Is there a simple thing like this that I can do? So i dont have to make the entire app not available to 1.5 users?

if (Android OS == >2.1){
//Insert code here that requires 2.1 and up}
else{
//insert code that would appear is OS is <2.1}

Android :: Way To Install A Specific Version Of Droid On Phone For Testing?

Sep 20, 2010

My boss recently gave me an HTC Wildfire phone for doing an Android version of one of our mobile apps, which is all fine and good, except that the app requires API level 8 (ie Android 2.2), and the phone itself only has Android 2.1 installed. After much googling, I discovered that this phone does support Android 2.2, and carriers will be rolling out updates over the air for this model phone "in the near future". Since I'm not entirely certain what our lazy carrier's definition of "near future" is, it would be nice if I could download images for particular releases and install them on my phone. Coming from the world of the iPhone, it seems that this should be something rather necessary in order to successfully develop an Android app. Yet, it doesn't seem that Google offers any Android OS updates themselves. Have I no choice but to wait for the carrier to release an update?

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 :: 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 :: Generating Device Specific Serial Number

Aug 12, 2010

I would like to be able to generate unique serial numbers for each Android device for use in unlocking an application. How could I do this? EDIT: The reason is I want to revamp a paid application and provide users who have paid for the old version, which will have a different package name, a way to obtain the full version by downloading an unlikable free version of the application. I would push an update to the old version that would generate and display the code that they could enter to turn the Free version into a fully functional version.

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 : Possible To Make A Free Demo Version Of Game To Be Used For Contest

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?

Android :: Install Error - Parsing The Package - Occurring For One Specific Device

Jan 21, 2010

My .apk file is confirmed working, however for users of the Motorola Milestone (which runs the same android version 2.0 and up) they receive the error upon attempt to install. I've googled and searched through the other questions here. The error seems to normally only appear if you did something wrong in the signing wizard or renamed the file. Is it possible that some kind of software difference on the OS build on these Milestones is preventing the install?

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?
