In Linux, or any other form of unix, os.execl and friends are a good choice for this — you just need to re-exec sys.executable with the same parameters it was executed with last time (sys.argv, more or less) or any variant thereof if you need to inform your next incarnation that it’s actually a restart. … Read more

It receives the current version & the URL from where download the new version, if necessary. The main app … Read more
Have you looked at the Java Web Start? It checks for updated module on the server and downloads it only if required otherwise things are cached locally on the client PC and starts from there.
Step 1: Add dependency (build.gradle (app)): dependencies { implementation ‘com.google.android.play:core:1.7.3′ … } Step 2: Check for update availability and start if it’s available private AppUpdateManager mAppUpdateManager; private static final int RC_APP_UPDATE = 11; In onStart() method: mAppUpdateManager = AppUpdateManagerFactory.create(this); mAppUpdateManager.registerListener(installStateUpdatedListener); mAppUpdateManager.getAppUpdateInfo().addOnSuccessListener(appUpdateInfo -> { if (appUpdateInfo.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE && appUpdateInfo.isUpdateTypeAllowed(AppUpdateType.FLEXIBLE /*AppUpdateType.IMMEDIATE*/)){ try { mAppUpdateManager.startUpdateFlowForResult( appUpdateInfo, AppUpdateType.FLEXIBLE … Read more
Google Play does not provide any official APIs for retrieving metadata. You could however, check the unofficial API at http://code.google.com/p/android-market-api/. Specifically, take a look at the Wiki page HowToSearchApps. The response to the query contains version information: { “app”: [ { “rating”: “4.642857142857143”, “title”: “Ruboto IRB”, “ratingsCount”: 14, “creator”: “Jan Berkel”, “appType”: “APPLICATION”, “id”: “9089465703133677000”, … Read more

All you need is to use your own Application class, not default one. public class MyApp extends Application { public MyApp() { // this method fires only once per application start. // getApplicationContext returns null here … Read more
To the best of my knowledge the shortest path for a Windows Scheduled Task to “do something useful in Access VBA” is: Create a Public Function (not Sub) in the database. For example: Option Compare Database Option Explicit Public Function WriteToTable1() Dim cdb As DAO.Database Set cdb = CurrentDb cdb.Execute “INSERT INTO Table1 (textCol) VALUES … Read more
To replicate this update behavior you need two things: An updater application which checks for updates regularly. If an update is found it should install it automatically. Most commercial setup authoring tools include good updater applications. You can try writing an updater yourself, but it’s not as easy as it sounds. Per-user installations for each … Read more
Have spent a long time trying to disable updates (literally hours, reading forums and testing various (some exotic) solutions), and this was driving me crazy. But there what seems an infallible solution (see further down). Even using the official Google page with the templates did NOTHING: https://support.google.com/installer/answer/146164?hl=en I followed scrupulously the instructions of that page, … Read more
