I'm developing an application that will most likely be preinstalled on devices. It will be also available on Google Play. Is there a way to update those instances that are not downloaded through Google Play, since Google Play won't notify users about an update.
I was thinking about, as suggested here, trying to contact my site periodically, and when update is available, download it.
Is there a way to do this update automatically, or even silently, so that user doesn't have to do anything (like running the package manually). Or, when my site shows update is available, to offer users an update through Google Play, even though it's not installed through Market (EDIT: This Google play option would be preferable, because than users wouldn't have to check "allow install of non-Market sources".)
i had the same issue, now i check at the start of my app if theres a new version in my configuration xml.
I compare the actual version with the tag "< app_version >1.1< /app_version >" of my configuration.xml
if its lower i ask with a custom AlertDialog if the user proceed with the upgrade
Intent intent = new Intent(Intent.ACTION_VIEW ,Uri.parse(myapk_link));
startActivity(intent);
after the download the user has to run the package manually.
if you choose the update from the Android market use:
Intent intent = new Intent(Intent.ACTION_VIEW ,Uri.parse("market://details?id=com.package.name"));
startActivity(intent);
com.package.name must be the "package" of your app
or
Intent intent = new Intent(Intent.ACTION_VIEW ,Uri.parse("market://search?q=" + APP_NAME));
startActivity(intent);
Just found a way that works. Fire an Intent for a Market that searches for my application.
Tested with OpenIntent Newsreader because for it was easy to find an older version .apk. Market finds an application, and when user clicks install, replaces older version with the one from the Market. I think that is much easier solution for a user than downloading manually .apk and running it.
Intent intent = new Intent(Intent.ACTION_VIEW ,Uri.parse("market://search?q=" + APPLICATION_NAME));
startActivity(intent);
Is there a way to update those instances that are not downloaded through Google Play, since Google Play won't notify users about an update.
Old question, new answer:
After digging on exact the same question (pre-installed app on device, how can I provide a update through Google-Play) I found this information on support.google.com*:
Google Play can manage updates to preloaded applications, provided the following conditions are met:
The preloaded app needs to be in the system partition
The preloaded app needs to be free
The preloaded app needs to be signed with the same signature as the app published in Google Play
The Package Name of the preloaded and updated app needs to be the same
The Version Code of the updated app needs to be greater than that of the preloaded app

Then you need to be talking to the device manufacturers and asking them your questions. Nobody else will be able to tell you what is and is not possible, given their device and the carrier(s) that will distribute it. The answers will depend heavily on how they create their firmware, whether your application will be part of the firmware or "installed" as a normal app, what their arrangement with the carrier is vis a vis firmware updates, etc. You may not even get a vote in the matter.
Here is the option for latest version update
https://developer.android.com/guide/app-bundle/in-app-updates#update_readiness
try this google library to update from the application
dependencies {
implementation 'com.google.android.play:core:1.5.0'
...}
I hope this will help anyone
If whoever bundled the app on the device does a proper job of it, then the app will still have a market link (even as a system app) and Market will prompt the user to upgrade it if a new version is available. After all, that's exactly what happens with an app like GMail that's pre-installed on phones.
You cannot install or upgrade a package automatically. Only the Android Market is capable of doing this (i.e. it silently updates itself).
You can certainly download a package and fire the Intent to install it, but the user will have to have the "Allow non-Market apps" options enabled, and they'll still have to manually approve the install/upgrade.
One place to possibly investigate is how Google Maps does it. This is generally pre-installed, but always appears to be shown as an update in the Android Market app, I believe. Whether there's a special flag in the packages.xml or manifest, I don't know.
There is a nice service that helps your app keep itself updated. Take a look at https://www.pushlink.com
In this product there is a NINJA mode that allows to perform updates without user interaction.
For other "modes", enabling "Install non-market app" is still needed. If it not enabled, the installation process is going to ask for it and redirect the user to the Application Settings, and after that, the user can install the app.
It's possible to fully automatically update an app, if you can sign an app as a system app. We wrote an app for specific hardware, we created an update app that the manufacturer signed for us. The update app runs on device startup, checks current version of the app and the new version, and installs the new version if necessary.
The use case would be a kiosk app, on tablets of one make and model, that don't have Google Play.

Is it possible to 'block/prevent' users from using an old Android app?
I mean - I've already unpublished app from Play. This means that app is not available anymore for downloading.
But I'd like to restrict users to carry on using current installed app (which has been unpublished from Play).
Is it somehow possible?
Regards,
There isn't a way to check if the app is currently published to the Play Store, however you can check if there is a new version available.
From the link above:
String response = SendNetworkUpdateAppRequest(); // Your code to do the network request
// should send the current version
// to server
if(response.equals("YES")) // Start Intent to download the app user has to manually install it by clicking on the notification
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("URL TO LATEST APK")));
Treating your users like this is not something you should do. Users have an expectation that once they have acquired an app they can keep using it, and you should respect that expectation.
But let's suppose there was a seriously good reason for doing it. Suppose your signing key and developer account had been compromised by an ex-employee, and you wanted to make sure users moved from the compromised app to a new app with a new package name.
You could then issue an update to the app which when loaded did nothing except display a message saying something like "This app is out of date and will no longer be updated. Please move to this app" and have a link to the new app in the Play store. Existing users would get the update, and while the old app is available to them, most users would not be able to get it.
As I said, this is very disrespectful behavior to your users in most situations, and I'd only recommend doing it if critical for user security.
I am currently investigating ways of remotely updating an Android app installed on a number of devices. The app in question is to be used on phones which we will provide to a number of demonstrators as part of product presentations. For this reason we don't want to publish the app on Google Play to be available for the public at large.
I've read that you can restrict access to the device on Google Play, but only according to criteria such as location, device type, android version, etc. Another way is to set up a version for beta testing, for which you can select testers, however this is only available to those who are part of a Google group or a Google+ community (according to here).
I've come across another post which details how to install an apk programmatically, however it appears to install the apk automatically, ie it doesn't appear to check whether or not the update is actually a new version.
One idea I have in mind is to upload new version on a repository and broadcast to devices which have the app installed, of which we have stored device ids. Is this possible?
What we do is sync periodically to a remote server during data entry on the app. During this sync, we check to see whether the device has the latest version of the software. If it doesn't, the new apk is downloaded and the user is prompted to install the software.
This is accomplished using a separate installer app we created. We have a service that keeps the app alive in the background, so it looks like the user never actually leaves the app during the install.
Would be happy to post code on the installer.
You can see the self installer here: https://github.com/techartist/SelfInstall-Jelly-Bean/
You should try Beta by Crashlytics, it's email-based.
You should try beta or alfa testing in gplay.
Also you can hardcode the date of ending and not to open application after this date.
I am trying to install APKs from our file server, and it needs to be done silently without the user being able to choose whether or not it's installed or accept permission settings/changes. This is a legit business requirement as we are working with a device vendor to preload our applications into /system/app. This is a custom Android tablet device, and as such, our business unit want to ensure we can push app updates (i.e. force the latest version).
I understand the usual security restrictions, but there seems to be a mechanism to install applications silently for vendor/manufacture level apps. However the information on how to do this seems very spotty at best.
It seems the package installer must be in /system/app and the installer must have the same signing cert key as the app being installed. That's not a problem, but info on how to implement this feature using this flow is something I have yet to find.
Anyone ever done this before?
I'm fairly certain you'll need to ship them a custom Android ROM that allows you to be able to do this (which I doubt their business will enjoy).
The Amazon App Store on a normal device can't install silently in the background like Google Play can. Maybe the Kindle Fire can do this (I don't own one), but if it can, its because its running on a custom ROM built by Amazon.
The best thing you could do is launch an intent that tells brings the user to the app needs to be updated, which brings them to installer activity, which then requires user interaction.
Not exactly an answer. However, we recently faced similar requirement for an android client-server app.
Whenever the application contacts server with a request, it sends the current versionCode as well.
PackageInfo pInfo = getPackageManager().getPackageInfo(getPackageName(), 0);
//pInfo.versionCode;
//pInfo.versionName;
On server side we check the versionCode and if we have a new version, informs the client and client forces the user to upgrade to the new version. The client app will not work until it is upgraded to the new version. But obviously user can choose to not install etc.
Hope it helps.
If i have a system app on an Android with the same package signature and that has a new version on the Android Market will the Market detect it and be able to update it?
(For example an app that a Carrier adds to the OS).
UPDATE:
Managed to validate this anwswer (marked it as resolved already)...but a new one appeared: Why doesnt the market show the system app on "my apps" when an update is available?)
In short: Yes.
After you install them, you will have the option of "uninstall updates" instead of "uninstall" as you see for the regular apps.
However, most carrier apps don't have updates through market, only google apps do. (For example: Gmail updates fairly often while SpringID may never update because they are not on the market)
In one of our projects where we are implementing an application using Android/HTML5/JavaScript there is a requirement for having an Android Auto update kinda feature which is as described below:
Update Native version: The Native version of our application should be easy to update. New versions should be possible to “push”, or at least notify, the user of. Does this require that we publish it to the Android Market?
As of now Notification of the new version can be send to the device but we need an approach to automatically download the new version and install ie., either update the existing version or overwrite it. Hosting the new version in Android market is the last option according to the client
If someone/somebody has earlier come across or implemented such a feature, could you kindly reply back.
If you are using the Android market , the best solution is to just notify the user that an update is available. Depending on the update or Application you may decide not to allow the user the access the app if an update is available.
You will always need to push a new APK to the market , the user may setup the auto update feature but I believe there is no way for an app to force the setting.
Any method which will allow the app to auto update would either need more privileges from users or a routed device , which I guess is not a big enough percentage of users to try the feature.
The android market allow to auto-update applications. Is you want to do it without using the android market, your users will have to enable apk install from unknown sources and they will have to confirm each installation (unless their phones are rooted I think)
There is a nice service called http://push-link.com
This hosts you APK and manage updates. You can choose how the user is going to be notified and see the progress installation of all version.
Cheers...
