Android :: How To Share Data Between Applications With No Dependency
Sep 19, 2010
I want to share data between 2 applications. the idea is both applications can write and read the SAME data and there is no dependency which one of the apps is installed or first created the data. I have 2 version of the same app: regular and premium and I don't know which of them will be first installed and both of them can change it.I tried to use ContentProvider but the problem is that only the first app can create the Provider and when it is uninstalled it deletes that custom Provider. I want the Content to be kept for the second app. Also, I tried to use Settings.System which keeps the data regardless if the application is installed or not but I don't want to use the permission for that (it is very problematic from user perspective). BTW, it seems that I can change ANY of the Settings.System which is not secured from Android OS perspective - but this is a subject for other post.

I want to know how to know the dependency between applications. Calender needs CalendarProvider, Phone needs TelephonyProvider etc And more complex example is that com.android.music depends on android.process.media and /system/bin/mediaserver.

I did a few searches but couldn't find anything specific to what I'm talking about. My wife and I both got Droids the other day and love them. We are enjoying finding apps and all that stuff, but one thing I haven't been able to figure out is how we can share applications between us. Granted I dont want to illegally share apps with random people and friends, just between my wife. Not big into paying for 1 app 2 times so that we can share an experience. We both have ipod touch's, and we have always been able to share the apps with that by my 'authorizing' her ipod to match mine. She still has her email and all that, just we share a purchasing account. I imagine there is a backdoor way to copy apps and api's, but i dont want to get into that. I used to have a custom rom winmo and part of the appeal of the droid was it would do everything i want without having to crack it. I heard google was thinking about app sharing, and app2sd is in official development, but is there anything I can do now?

I have an app that creates a new data entry in a sqlite db with several columns. I would like to have a simple share button on the final activity so they can share the results (or even a simple text field) with apps that accept it (email, mms, twitter, etc..). I did some reading on ContentProviders but the more I read, the more I'm thinking i'm heading down the wrong path.

I've added the intent-filter. And when I tap "share" in the Gallery, it will launch my activity.
<intent-filter>
<action
android:name="android.intent.action.SEND" />
<category
android:name="android.intent.category.DEFAULT" />
<data
android:mimeType="image/*" />
</intent-filter>
But I don't know how to get the correct data from the current intent.

I want to create an app that contains a Service S and an Activity A. The Service S is responsible for preprocessing, such as preparing the data shown on the UI of the Activity A, before the Activity A gets invoked.I want to be able to invoke the Service S from outside the package, say from another Android app's Activity class B, do the preprocessing, and then when the data is ready, invoke Activity A. What is the best way to share data between the Service S and Activity A?How can the external activity B communicate with the Service S to determine if it has completed with all its preprocessing, and the Activity A is ready to be invoked?

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...

Suppose you have an app with a lite version and a full version. The app stores some user data in SharedPreferences, and some data in a SQL database. If a user tests the app for a few days, generating data all the time, and then decides to switch to the paid version, how do you copy or share the data between the two? Some code examples would be appreciated - but for some reason I have a feeling this is much, much more complex than I hope.

"Facebook for Android" is great, but I just wonder that whether my application can use the share function of it. Or, does the ""Facebook for Android"" release some apis and let other applications use the built in functions like "share" or "feed"?

I looked into some examples of sharing data to other apps using content Provider. All these examples talks about sharing sqlite dbs. I need to share data under shared Preferences of my app to other apps using content Provider. Can I use content Provider to do that ?. Please let me know some pointers or sample code to share data other than sqlite db using content provider.

It would be nice if StackOverflow had a section where we could post tutorials like mine so that I can answer literally hundreds of questions that have been asked here with a single blow. See... every day I read questions about how to pass complex objects between activities, how to save state so that your app can resume after orientation change, how to update listviews when the data changes, etc, etc. Here is the second part of a tutorial series I posted on my blog... I hope that you actually read it... because I haven't seen any examples like it anywhere... and it has changed how I think about developing for Android across the board. The question is... is there a downside or negative affect of developing like this?
Beyond Smart Lists - How Observable Singletons change the game. Please read through both of these tutorials carefully... I will answer any questions about it here that I can... I really want to know what you think about this and if it might solve issues for you. NOTE TO MODERATORS: there are no advertisements of any kind on my blog.. so don't just close this because you think I am spamming somehow... I am not going to duplicate my post here.

I'm looking for a solution to connect one android phone to another over bluetooth to share voice and maybe data service. What I want to do is use my old Dell Streak as a GPS/media player in my car without having service to it. I would like it to connect to my current phone so I can make call through it, like a headunit with hands free bluetooth calling. I'm not so much worried about data, though it would be a plus but I don't think Android supports connecting to ad-hoc networks. I can't seem to find any app that supports this, and I'm not seeing anywhere on the Android system where this is possible. I haven't owned a car stereo that supports bluetooth calling so I'm not sure what to look for.

Password manager that can sync between multiple devices? The only one I found was Keeper but it's $10 for each install which would run me 20-30 bucks for 2-3 devices. My wife and I need to be able to access password/logins and share the data.

Trying to make Tasker automatically open and populate Astrid todo's task edit fields the way that so many other apps can using the Share menu. With pretty much any app being able to do this using Share, I figured it wouldn't be too hard to make Tasker do the same, but I'm having trouble finding out how.
I'm using the beta of Tasker so Send Intent replaces the previous two intent actions. The fields available are Action, Category, Mime Type, Extra, Package, Class, and Target. Right now Package is set to com.timsu.astrid and Class to com.todoroo.astrid.activity.TaskEditActivity, which manages to open the task edit screen. That intent is however from the Astrid widget so I don't know if that's even the right thing to use if doing this via the Share ability.

I have a module called MyApp, and another module called MyAppTests which has a dependency on MyApp. Both modules produce APKs, one named MyApp.apk and the other MyAppTests.apk.I normally build these in IntelliJ or Eclipse, but I'd like to create an ant buildfile for them for the purpose of continuous integration.I used "android update" to create a buildfile for MyApp, and thanks to commonsware's answer to my previous question I've been able to build it successfully using ant.I'd now like to build MyAppTests.apk using ant. I constructed the buildfile as before using "android update", but when I run it I get an error indicating that it's not finding any of the classes in MyApp.Taking a que from my previous question, I tried putting MyApp.apk into my MyAppTests/libs, but unfortunately that didn't miraculously solve the problem.

I'm using google moderator as a simple way to collect feedback for my application. There's a google moderator app on the market that provides a better interface than the website for mobile users.Getting to the point: Is there a way to get it to install along with your application or a reasonable way to identify if another package is available so I can direct users to the market to download it?

I have a and Android project and its test project. I can run tests successfully in the emulator. As the Android project has dependencies on a third library project, I want to use classes of the third project in the test cases too. For this, I need to add a dependency from the test project to the third project as well. Compile-time this works, but when I do a remote run of my AndroidTestCase, all tests fail. For each test, I get a NoClassDefFoundError, but not for third project classes, but for a class in the Android project itself!

I have a preference where I'd like to toggle the state of a preference depending on the state of a checkbox. This works wonderfully if I want something visible when it's checked.However I want another preference to be visible when it's NOT checked.Is there a way to specify "android:dependency= !"pref_server_active" or android:dependency= NOT("pref_server_active") ?

I'm using maven-android-plugin in my android application. I'm a dependency which maven download from remote repository before APK build. But if I want to debug the APK in emulator it does not include the those maven dependency and as a result APK does not run with normal Run (using Eclipse) and can not be debug as well. Could someone know how to debug in this situation?

Is there XML attribute that does the exact opposite of android:dependency? What I would like the dependent preference to be enabled when the other is not checked and disabled when it is checked. Maybe the issue isn't with android:dependency maybe there is an xml attribute that I can add to make the default for that preference disabled and then android:dependency will toggle it the opposite way like I want. I tried setting android:enabled="false" in the preference and it disables it like I want but even with it being dependent on the other preference it didn't enable it like I had hoped.
