Android – how to use Google play to update apps and force Downloads

I am using Android studio. I have developed an application and now I want to upload it to Google play. I have a license and have uploaded an application before, but I really didn't know what I was doing

What I want is to upload my application to Google play and upgrade it without losing comments and ratings. What do I do?

Moreover, what is the best way to force users to download updates? I want to upload the app to Google play and Amazon Appstore (for Android), so linking to Google play or similar content may not be the best solution. I was thinking - toast "please update the app". What do you think?

resolvent:

To update an existing APK on the Google play store:

1) Go to your Google play developer console

2) Select all applications, and then select your applications

3) Select upload APK

4) Select from the production, beta or alpha channels, and then select upload APK

More information about upload, publish, etc

Force user updates: there are three things

1) It cannot be used in the Google play store unless the user has set up automatic update

2) You can use external libraries, such as updatechecker, Appupdater, and so on

3) You can change the application structure in the following ways: whenever the user starts, the internal content of the application will be updated. (I guess this is not a feasible option)

What is KeyStore?

It is used to build a single APK

Keep the keystore in a secure location. If you lose the keystore, you need to publish the application with a new package name and a new key. If you need to do so, you should also cancel publishing the original application and update its description
