Use Play Core library to achieve same / better results.
ForceUpdate
Force your users to update the app, or notify about non-critical updates.
This library is currently in concept phase. Feel free to star it, but do not try to use it :-)
Download
Download the latest JAR:
or include via Gradle:
compile 'net.skoumal.forceupdate:force-update:0.1.0'Recommended usage
Only few lines of code are needed to notify and force your users to update your application in serious cases, such as a critical error or backend incompatibility with an old version of your app.
First, create a JSON file in this format and publish it:
{
"min_allowed_version": "1.0.0",
"excluded_versions" : [ { "version" : "1.0.3" }, { "version" : "2.0.1" }]
}Now add ForceUpdate initialization to your Application.onCreate():
new ForceUpdate.Builder()
// required - needs android.app.Application object
.application(this)
// load all data from your json file
.masterVersionProvider(new JsonHttpMasterVersionProvider("http://your.domain/path/to/above.json"))
// with exception for new version notifications
.recommendedVersionProvider(new CarretoGooglePlayVersionProvider())
// we are done
.buildAndInit();Now all your users will be:
- forced to update all installations with versions below 1.0.0
- forced to update installations with versions 1.0.3 and 2.0.1
- notified about available update with every new version on Google Play
Version providers
You can load your version requirements from any place and any format. There is set of ready-to-use version providers, but you can also create your own if you need something special.
By default, every provider is polled once every 24 hours for its version.
new ForceUpdate.Builder()
// required - needs android.app.Application object
.application(this)
// custom provider for minimal required version
.minAllowedVersionProvider(new MyCustomVersionProvider())
// poll the min-allowed-version provider every 4 hours
.minAllowedVersionCheckMinInterval(4 * 3600)
// custom provider for recommended version provider
.recommendedVersionProvider(new AnotherCustomVersionProvider())
// poll the recommended-version provider every 6 hours
.recommendedVersionCheckMinInterval(6 * 3600)
// custom provider for exluded version list
.excludedVersionProvider(new MyExcludedVersionListProvider())
// poll the excluded-version provider every 8 hours
.excludedVersionCheckMinInterval(8 * 3600)
// you can also load apk version your own way if needed
.currentVersionProvider(new ApkVersionProvider())
.buildAndInit();Sometimes you need to load more data from one physical source, like in the first example where we load min-allowed and excluded versions from one JSON file:
{
"min_allowed_version": "1.0.0",
"excluded_versions" : [ { "version" : "1.0.3" }, { "version" : "2.0.1" }],
"recommended_version" : "3.0.3"
}You can load all three versions from JSON file above
new ForceUpdate.Builder()
// required - needs android.app.Application object
.application(this)
// one provider for all versions, can be overwritten by methods above
.masterVersionProvider(new JsonHttpMasterVersionProvider("http://your.domain/path/to/above.json"));
.buildAndInit();View customization
Simply define your own views for Force-Update Activity and/or for recommended-update Dialog:
new ForceUpdate.Builder()
// required - needs android.app.Application object
.application(this)
// defaults to predefined activity
.forcedUpdateView(R.layout.force_update_activity)
// defaults to predefined dialog
.recommendedUpdateView(R.layout.recommend_update_dialog)
.buildAndInit();Use your own activities:
new ForceUpdate.Builder()
// required - needs android.app.Application object
.application(this)
// defaults to predefined activity
.forcedUpdateView(MyForceUpdateActivity.class)
// defaults to predefined dialog
.recommendedUpdateView(MyRecommendedUpdateActivity.class)
.buildAndInit();Or provide completely custom implementation of UpdateView interface:
new ForceUpdate.Builder()
// required - needs android.app.Application object
.application(this)
// defaults to predefined activity
.forcedUpdateView(new MyUpdateView())
// defaults to predefined dialog
.recommendedUpdateView(new OtherUpdateView())
.buildAndInit();Usage
This library was designed with full customisability in mind. Whole library is based on three simple terms:
-
VersionProvider - provides version from a source, for example from your APK, Google Play, your server, or any other third party service. You can choose one of existing VersionProviders or create your own.
-
UpdateView - abstraction of the way how we notify user about new version available (recommended update) or about necessary update (forced update). Predefined Activities and dialogs are available as well.
-
CheckInterval - how often should we poll VersionProvider for new data. The under-the-hood strategy is to poll with every Activity.onResume() event if MinInterval is already reached.
Use the simple builder in your Application to init ForceUpdate:
new ForceUpdate.Builder()
// required - needs android.app.Application object
.application(this)
// defaults to NULL - no force update view will ever appear
.minAllowedVersionProvider(new MyCustomVersionProvider())
// defaults to 24 hours
.minAllowedVersionCheckMinInterval(4 * 3600)
// defaults to version from http://carreto.pt/tools/android-store-version/?package=<your package>
.recommendedVersionProvider(new CarretoGooglePlayVersionProvider())
// defaults to 24 hours
.recommendedVersionCheckMinInterval(6 * 3600)
// defaults to NULL - no force update view will ever appear
.excludedVersionProvider(new MyExcludedVersionListProvider())
// defaults to 24 hours
.excludedVersionCheckMinInterval(8 * 3600)
// defaults to current apk version
.currentVersionProvider(new ApkVersionProvider())
// defaults to predefined activity
.forcedUpdateView(new ForcedVersionActivityView())
// defaults to predefined dialog
.recommendedUpdateView(new RecommendedVersionView())
// one provider for all versions, overrides all VersionProviders
.masterVersionProvider(new MyMasterProvider());
// alias for .build().init()
.buildAndInit();Extras
ForceUpdate is able to detect crash during last version check and hangs main thread during next app start to avoid any other code execution and allow successful version check. If there is a new version available it automatically fires a notification.
