Update an Android app (without Google Play store visit)
Solution 1
Absolutely. You will need to build a mechanism, though, for your app to call home to the server, find out if there's a newer version of the app, and if there is, pull it down and install it. Once you've determined that you do need to pull down an update, you can do that with something similar to this AsyncTask:
protected String doInBackground(String... sUrl) {
String path = "/sdcard/YourApp.apk";
try {
URL url = new URL(sUrl[0]);
URLConnection connection = url.openConnection();
connection.connect();
int fileLength = connection.getContentLength();
// download the file
InputStream input = new BufferedInputStream(url.openStream());
OutputStream output = new FileOutputStream(path);
byte data[] = new byte[1024];
long total = 0;
int count;
while ((count = input.read(data)) != -1) {
total += count;
publishProgress((int) (total * 100 / fileLength));
output.write(data, 0, count);
}
output.flush();
output.close();
input.close();
} catch (Exception e) {
Log.e("YourApp", "Well that didn't work out so well...");
Log.e("YourApp", e.getMessage());
}
return path;
}
// begin the installation by opening the resulting file
@Override
protected void onPostExecute(String path) {
Intent i = new Intent();
i.setAction(Intent.ACTION_VIEW);
i.setDataAndType(Uri.fromFile(new File(path)), "application/vnd.android.package-archive" );
Log.d("Lofting", "About to install new .apk");
this.context.startActivity(i);
}

Yes it is possible, here is roughly what you can do:
Get the current application versionCode
PackageInfo packageInfo = getPackageManager().getPackageInfo(context.getPackageName(), 0); int curVersionCode = packageInfo.versionCode;
Have a server where you host the apk file and create a simple plain file containing only one integer, which represents the latest application version code.
When the app starts (or whenever you want to check for an update), retrieve the latest versionCode from the server (i.e via an HTTP request) and compare it with the current app version.
If there is a new version, download the apk and install it (will prompt a dialog for the user).
Edit:
You can use the code of @Blumer for this.
Solution 3
it is possible, however keep in mind that the user will have to have "Allow installation of non-Market-applications/unknown sources" enabled in their settings.
Solution 4
FYI, i just read about this at http://blog.vivekpanyam.com/evolve-seamlessly-deploy-android-apps-to-users/?hn
Evolve is a library for Android Developers that lets them deploy new versions of an app without going through Google Play or asking users to download an update. It works by using reflection and dynamic bytecode generation to "trick" Android into running new code.
Its alpha though, but it seems possible via a lot of hoops. I doubt if its worthwhile except for malicious software..

Official support/library for In-app updates Google play core
- In-app updates is a Play Core library feature that prompts active users to update your app. The in-app updates feature is supported on devices running Android 5.0 (API level 21) or higher, and requires your app to use Play Core library version 1.5.0 or higher. Additionally, in-app updates are only supported for Android mobile devices, Android tablets, and Chrome OS devices.
Below are type of Update flows
- Flexible updates (Sample screen)
- Immediate updates (Sample screen)

I wrote a Beta version of the application. It will be available for download through the web (I will not publish it to the Play Market). Is it possible to update this application without Play Market visit when the new version will be released?
-
Eluvatar over 11 yearsyes it is possible. Outside of that, what have you tried? and how in depth do you want it to go? auto update download and install? or open browser download and install?
-
IQW over 11 yearsThanks for your answer, but Blumer have already gave me an answer with example of code. I think for my case it's enough. Thanks again)
-
TheCoderGuy about 5 years@IQW Can you please show the code what did you try because I have the same problem I need to check from a domain there I have uploaded my apk and to check if there is new version or not ?

KingAlex1985 almost 10 yearsQuestion: What happens with "publishProgress((int) (total * 100 / fileLength));"? Where will this Methode be called and what is it doing? Thanks in advance.
-
chandimak about 9 yearsHave you got an idea what happens if above setting disabled at the time of uploading the app.
-
stephanlindauer about 9 yearsuploading to where? the market? its a setting on the device not in the binaries or the market. this is what i mean: tech-recipes.com/wp-content/uploads/…
-
chandimak about 9 yearsSorry. Misspelled. I wanted to say 'updating' not 'uploading'. So, when there's an update to the app and at that time the status of the above setting is 'disable' what would happen. Does it automatically allow updating or user explicitly need to set above setting 'enable' again.
-
stephanlindauer about 9 yearsas far as i can remember: you would be able to download the apk but you wouldnt be able to install it. but its worth checking the current state of affairs. i think google wanted to completely ban those self initiated updates.
-
stephanlindauer about 9 yearswill the apk be automatically deleted afterwards?
-
johndodo almost 8 yearsA few points to consider if you use this solution: 1) yes it must be external storage - internal is not shared between apps and is not visible to "installation app" 2) you can't use content provider because this is not supported by "installation app" (needs to be file://...) and 3) you probably want to use
Environment.getExternalStorageDirectory()
instead of hardcoded path. Otherwise this solution works, thanks! -

Dan Harris about 6 yearsOn Oreo (Possibly older versions too) if you don't have that permission set the OS will tell you this is required and take you to the appropriate setting. You can configure from there the list of apps that can install from unknown sources - The user will need to set your app to allow this

TheCoderGuy about 5 yearsAnd as what is the
publishProgress
declared because I used this code but thepublishProgress
is not declared ? And it is the same with the@Override
