Android :: Transfer Preferences From Demo To Paid Application
Nov 16, 2010
This comes up because I am changing the model for my freed and paid apps. Besides all the other things I need to figure out to build this (I'm trying the library method), I'd like to transfer preferences smoothly from DEMO app to paid App. I'm sure that some of you are old hands at this and can give some advice. I've tried the Demo and License, where a license app will unlock the Demo app and make it full.
The Market users can't handle that. My customers didn't want to have two app icons once they installed the license. So I made it invisible. Now I have users that say they can't "open" the license after purchase. It states very clearly in the app description that they need to install the free version first, but I've discovered that not everyone reads that vast 325 character description before buying even some of the most expensive apps on the Market.
I've decided not to fight it. I do believe that customers will be more happy overall and there will be less refunds, if they do try the demo app first. It gives them 16 days to try instead of 24 hours to get a refund. But I'm not going to force that. So, I'll be going down the Demo and Full model route. Just as an aside, I really wish the market would support time limited trials. There is difference between real support and faking it as I have been.

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?

this question is now obsolete, as Android Market includes much more countries and such services as PayPal Mobile Payments Library are available.I'd like to sell my Android application, but I live in Poland and in my country* Android Market supports only free apps (we cannot sell and we cannot buy too).What is the best way to sell application in such situation? I can accept PayPal money transfers, but I don't know how to distribute APK package without exposing it to getting pirated. Did someone tried it already and succeeded? you may be surprised, paid apps are supported only in 12 countries worldwide.

I purchased a Galaxy a few months ago and installed the Galaxico ROM. Using the market enabler I was able to purchase paid apps (I'm from Ireland where we don't have a paid apps store). I've recently switched to a Milestone. To the best of my knowledge the market enabler will not work with the Milestone because it is not rooted yet.
Is there a way I can get the apps I've paid for already from my Galaxy to my Milestone? I bought CoPilot sat nav app, and this is what I'm thinking abut most. It was pretty expensive, and I'm not going to buy it again.
I contacted CoPilot and they told me I had to wait until the paid app store comes to Ireland. Is there any (legal) way I can get my CoPilot on my Milestone?

When I switch from my Droid to the Incredible, any chance the apps I paid for will be downloadable at no cost? I know going from a droid to a droid it wouldnt be a problem, but didn't know if the case was them same when going to a completely different model.

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?

I stepped on my first Eris (don't ask) and had to get a replacement through Asurion. Well, I thought when I got my new phone I would be able to redownload all the apps I had purchased but I cant. The Market wants me to pay for them all again. I guess the market tracks you specifially with your phone, not your account. So I called Verizon, of course they were no help. The chick didn't even try to help, I asked her if I could get those apps back and she stalled for a second like she really didnt know but also didnt want to take the time to find out, then she said NOPE. I was like man, that sucks, she said YEP! That was the end of the conversation. Surely there is a way for me to get these apps back without paying for them again? I know they are inexpensive but when you have 10 or so they start to add up! Not to mention I had my first phone for less than a month and hardly got to enjoy the apps I purchased. I've thought about emailing the dev's but dont know if thats a good approach or not.

I am using a PreferenceActivity to let the user set some values. I am feeding it the xml file with the defined preferences.
I have set all the android:defaultValue="" for them.
When I start my application, I need the preferences, or if they are not set yet manually, I want the default values:
CODE:.................
However, when android:defaultValue="true" I still get false. So, it looks like the defaultValues set in the XML are not used anywhere but when initializing the preferences-screen.
I don't want to hardcode the default values in the getBoolean() method. So, is there a way get the default-values with only defining these in 1 place?

I have a app that only consists of 2 services and a broadcast receiver (they check the internet periodically). I need to store preferences that can be shared across those services. Is this the same as for an activity? Just use getsharedpreferences()? This doesn't seem to be documented very well.

I have been looking for a method to change the default SMS application's preference programmatically.
I found that those preferences are stored as "shared preferences", probably in data/data/com.android.sms/something.xml, but I am not able to get to that directory since I haven't rooted my phone.
Do you have any clue?

I want to start with a consistent test environment so I need to reset/clear my preferences. Here's the SetUp for test I have so far. It's not reporting any errors, and my tests pass, but the preferences are not being cleared.
I'm testing the "MainMenu" activity, but I temporarily switch to the OptionScreen activity (which extends Android's PreferenceActivity class.)
I do see the test correctly open the OptionScreen during the run.
CODE

StartNewActivity Code:

Right now I've finished an application that I want to distribute on Android Market. It will have a payed version and a free version with some limited features. While developing it, I was doing obviously just the main project of fully featured release. And now after finished I've included a "boolean" DEMO_VERSION=true that restrict those features. My question is if it's possible to generate both apk from the same project? Or should I create new project with the same source but changing the Java package to tell android market that they're two different applications.

My application is used on multiple platforms so it saves it preferences to a file (rather than to the standard Android SharedPreferences).
Is there any easy of reusing the PreferenceActivity to save preferences to a file or is it a case of creating a whole new activity to do the job? If the latter is the case is there a layout I can use that will make the activity look like the normal preferences screen? PreferenceActivity uses com.android.internal.R.layout.preference_list_content but this doesn't appear to be available to apps for reuse.

What is "window.demo.clickOnAndroid()"? I know that clickOnAndroid is a method in my Android application. But what is window and demo? My file is called demo.html. Is that it?

I want to sell an application developed by me, but this service is not supported in my country (Romania).
So I want to ask a friend of mine who lives in a country (France or US) where selling paid applications is possible to help me with this.
Now I don't know exactly what to tell him about the process:
What is required by his side ? A bank account or a credit card ? How the money are transferred to him ? What exactly Google checks to verify if the developer is in one of the supported countries ?

I have an issue related publishing the paid app to android market. (My application is internet connection based app.) If I've put the app to the android market, can user who bought the app pass to anyone? How is its security (I mean safe of .apk file)? Also, what is payment tool of android market? My main point is choosing the best way to link paid user to our system. Actually I don't know how to link paid user account to my system(by email address or device unique ID? What is better way?).

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'm nearing the end of a small project to develop an android app. As a first time developer, and a one-man band, I am anticipating selling it at a low price point. I have followed some of the discussions on the Android blog and elsewhere about licensing and obfuscation, and I am in two minds. Part of me thinks that I have spent a long time on the development, so why should I make it easy for people to pirate the app? The other part thinks that it could be fairly time consuming to implement licensing and obfuscation, stop people using the app from non-google supported countries and wondering how much of an issue it is anyway for a small app.
However, if you google even a small app and add .apk at the end the number of "warez" downloads is fairly shocking if it's true. Just wondering whether anyone has any opinions either way, about the impact of piracy on a small developer. I'm not expecting to make my fortune with this app, and would aim for I guess 1000 downloads or so. I may even release an ad-supported version some way down the line depending on how sales held up, which would solve most of the problem I guess.

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?

I've been rooting my phone for about a month now, and I'm currently running Kangerade 5.0.9 (great job Jrummy) but I have a quick question about Titanium Backup. I have a feeling you will all be hesitant to answer, but Im going to ask anyway. Note I have no intentions of stealing here, Im just curious to see if this is a bug.
If I purchase a paid application from the market, back it up, and then refund the application, would titanium backup be able to restore it?

I have read on the market support that "If you have previously published an application for free, you cannot change it to have a price". But I was wondering, if at the contrary I change my app from paid to free and some time after I want to re change it from free to paid! Can I? And if yes, Have I to wait some period (I have read something like this in the contract)?

My android application has two kinds of preferences:
1) I have user preferences defined in res/xml/preferences.xml so that users can manage their preferences with a PreferenceActivity.
2) I'd like to define another file for global configuration preferences of my app.
What is the best way to manage my app config preferences? Should I create another XML file with config values or should I specify those config values in strings.xml? What is the best practice for managing config preferences?
