Notify users when there is new updates in Android - android

Is there anyway to notify the users (inside of my application) if newer versions is published? perhaps through Dialog?

Usually in web client android application we make a request to the server for getting the current version.
Use
String versionName = context.getPackageManager().getPackageInfo(context.getPackageName(), 0 ).versionName;
And compare and notify the user with a dialog.

Santosh's solution just allow you to access to the "android:versionName" attribute in your manifest.
look at Android Market Application Updates.

Defining custom uses_feature in android app

I know we can define a custom permission in one app and other app can ask for this permission using uses_permission tag.
My problem is, I have 2 apps and one app is dependent on other to work as expected. As both the apps will be updated from play store over time, their versions has to be in sync so that they can interact and work without any issues.
User should be able to install/update app B to version 2 only if they have already installed/updated version 2 of app A.
My idea is, if this can be handled by defining something (uses_feature where we can define version also, just like glesVersion) in manifest file itself, then user will not see update available of app B, if they have not updated app A already.
I hope I have explained my problem clearly. Please suggest some solution.
While opening your launcher activity all you ought to do is check
the version of that package you have installed and then show them the
update.
You need to figure out what is the right package name of your installed application on your device.
Getting Package Info:
PackageInfo pinfo = null;
pinfo = getPackageManager().getPackageInfo("com.yourapplication.android", 0);
//getVersionCode is Deprecated, instead use getLongVersionCode().
long verCode = pinfo.getLongVersionCode();
//getVersionName is Deprecated, instead use versionName
String verName = pinfo.versionName;
Then you can check in here like,
if(verName.contentEquals("your new version") {
// do something such as update
}
else {
// function normally
}
Hope it helps!

Force update for the latest version of android app

I am trying to figure out how to forcefully update the latest version from play store.
As the older version of my android app is already in play store where i haven't implement the check to get the current version of the app and compare with the play store app version like specified in the link update android app forcefully
I want that when I upload my new version on play store then user should not be able to use the app till he update the new version.
Could you please help me out.
I have to do the same thing but what i did i gonna share you i hope this will help you.
1> I get the previous code version of my application and store it the string.xml. like my live app version code is 1. And my new app version code is 1.1.
This code is tell us our app version code.
PackageInfo pinfo = getPackageManager().getPackageInfo(getPackageName(), 0);
int versionNumber = pinfo.versionCode;
String versionName = pinfo.versionName;
2> Than check
if (newcodeversion > previouscodeversion) {
// open any activity or pop up
}
3> And in the new activity place Text view with text "you have update version" and a button.And on the click of that button navigate to google play store.
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse("Your application URL"));
startActivity(i);
It is not possible if the logic of comparing the versionCode and blocking the user isn't already placed inside the current app on PlayStore.
This is not difficult to do. Simply bar the user from having the core functionality of what ever your app is responsible for.
Example, if it is a calling app, do a version check, and if the user has not updated as yet, restrict the use of call making entirely.
According to #pieter-b, taken from Forcing Updates:
For this to work, some kind of logic the app uses needs to be under your control. And then without that part of logic the app won't work
and you can show a message: "your app is out of date, please download
the new version to continue use."
Consider a messenger app where traffic goes through your servers. Just
refuse to deliver messages of clients using an outdated version.

How to autoupdate android app without playstore? Like Facebook app or any Contest app

How do apps update internally automatically without updating from playstore?
I mean the internal data of app is changed (via internet) without updating from playstore. For eg any Contest app, or Facebook app. Here the newsfeed is updated automatically.
What is the technical term for that?
Any tutorial on it?
If you would like to check if you app has updates (without interacting with Google Play), you'd have to poll a server (providing your current version) and let the server check if there is a newer version available. If that is the case, let the server respond with a changelog and an url to the newer version.
Luckily, there are libraries to do this:
AppUpdater. Android Library that checks for updates on your own server (or Google Play, Github, etc). Great documentation. This library notifies your apps' updates by showing a Material dialog, Snackbar or notification.
Android Auto Update. Chinese library, but should do the trick, one of the most popular libraries to do this, but this can be just because Google Play is not available in China.
AppUpdateChecker A simple non-Market way to keep your app updated.
All it requires to set up is a URL pointing to a JSON document describing your app's changes.
Auto Updater This project allows to automatically update a running APK application using a private update server (see apk-updater) instead of Google Play updater. Also comes with a server script.
SmartUpdates. Older library, but instructions in English and also provides a server script.
WVersionManager. Checks for updates, but actual update has to be downloaded from the Play Store.
Answer from Mdlc is about updating the app itself but not the content.
What initially asked is how to create an App with dynamic content such Facebook or any other newsfeed app.
Any kind of such apps has 2 parts:
Server
Client
Server stores the whole information you need and client make requests to that server and displays information.
Let's say server stores in DB one entry called News#1. Client requests list of news and get back array[News#1] as response and show one tile on screen. Then somebody creates new entry News#2. On next request to the server client will get array of 2 elements: array[News#1, News#2] and displays this dynamic content.
REST Api Client is what to start with.
https://github.com/bitstadium/HockeySDK-Android/blob/develop/hockeysdk/src/main/java/net/hockeyapp/android/tasks/DownloadFileTask.java#L194 has the perfect and still working implementation on opening a downloaded APK file...
private fun install(downloadedAPK: File, context: Context) {
val intent = Intent(Intent.ACTION_INSTALL_PACKAGE)
intent.setDataAndType(Uri.fromFile(downloadedAPK),
"application/vnd.android.package-archive")
intent.flags = Intent.FLAG_ACTIVITY_NEW_TASK
var oldVmPolicy: StrictMode.VmPolicy? = null
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
oldVmPolicy = StrictMode.getVmPolicy()
val policy = StrictMode.VmPolicy.Builder()
.penaltyLog()
.build()
StrictMode.setVmPolicy(policy)
}
context.startActivity(intent)
if (oldVmPolicy != null) {
StrictMode.setVmPolicy(oldVmPolicy)
}
}
Also have a look on AppCenter (Former HockeyApp) in-app updates https://learn.microsoft.com/en-us/appcenter/distribution/inappupdates
Here is the alternate
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'
...}
You can try this library: implementation 'com.github.vermat516:HelperLibrary:1.0.1'
This is best from my view we only have to write is:
new UniversalHelper(this).updateApp();
Rest of the work will automatically done by the library
This is response how your app will look like[This]

how to do updation through an external button for android app(cordova)

I know that for updating we need to increment the versionCode and versionName in androidManifest file and then playstore will find if there is any mismatch in these value then it'll notify the user that update is available.
But I want a button for update which will check and notify accordingly.
If it is an application on the Market, then on app start-up, fire an Intent to open up the Market app hopefully which will cause it to check for updates.
Otherwise implementing and update checker is fairly easy. Here is my code (roughly) for it:
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")));
You can host a service on a server which returns the current version of the application which is out there on the market. According to the value you can decide to intimate the user. If you want to do it programmatically, you would have to write a plugin for your cordova app.

how to determine an application version from own application

IThe scenario is that my application search all installed application in order to determine versions of those applications. Then store name of the application with its versions on the same file. If new version of the application is available, then give notification to the user. The question is "how can I learn the version of the other application from my application ?"
Thanks for all your help
Something like this should work to get the current version:
List<PackageInfo> packages = getPackageManager().getInstalledPackages();
for(int i=0;i<packages.size();i++)
{
int version = packages.get(i).versionCode;
// do whatever with it here
}
Getting the most recent version in the Play Store doesn't really work, though. Like A--C said, you could check versionName instead, and just notify as updated if the two aren't exactly the same(don't worry about higher/lower, just inequality).
You can do following (inside of Activity or any other Context)
getPackageManager().getPackageInfo(getPackageName(), 0).versionName
getPackageManager().getPackageInfo(getPackageName(), 0).versionCode
