3.0.0
General
RuStore In-app updates SDK enable users to be kept up to date with the latest app version on their device. This allows them to stay informed about any performance enhancements or bug fixes that have been implemented.
User scenario example
Additionally, the SDK offers the ability to notify users of a new version and provide an option to install it. The installation process can occur in the background, while the user can track the progress of the update.

Prerequisites
For RuStore In-app updates SDK to operate correctly, the following conditions need to be met:
- Android 7.0 or later..
- RuStore app version on the device is up-to-date..
- The user is authorized in RuStore.
- RuStore app is allowed to install applications.
Connecting to project
- Copy the plugin projects from the official RuStore repository to GitFlic.
- In your IDE, open the Android project from the
unreal_plugin_libraries
folder. - Build your project with the command
gradle assemble
.
If the build is successful, files will be created in unreal_example / Plugins / RuStoreAppUpdate / Source / RuStoreAppUpdate / ThirdParty / Android / libs
and unreal_example / Plugins / RuStoreCore / Source / RuStoreCore / ThirdParty / Android / libs
:
- RuStoreUnityAppUpdate.aar.
- RuStoreUnityCore.aar.
- Copy the contents of
unreal_example / Plugins
folder to thePlugins
folder inside your project. Restart Unreal Engine. - In the plug-in list (Edit > Plugins > Project > Mobile) select RuStoreAppUpdate and RuStoreCore.
- In the
YourProject.Build.cs
file ofPublicDependencyModuleNames
list, connect theRuStoreCore
andRuStoreAppUpdate
modules. - In the project settings (Edit → Project Settings → Android) set the Minimum SDK Version parameter at least to 24 and Target SDK Version parameter to 31 or later.
Создание менеджера обновлений
Create update manager before calling library methods.
How to initialize a library
Initialize the library before calling its methods.
URuStoreAppUpdateManager::Instance()->Init();
All operations with the client are also accessible from Blueprints. Below is an initialization example.
![img](/help/en/assets/images/e15a78a1e10ef50433ef69d09c0703b2-dbccbc22deb17f0c5445daa29d4e2065.jpg)
The Init
call ties the object to the scene root, and, If no further work with the object is needed, execute the Dispose
method to free memory. The Dispose
method call will untie the object from root and securely complete all sent requests.
Deinitialization
URuStoreAppUpdateManager::Instance()->Dispose();
![img](/help/en/assets/images/6fd48121e64626989ccc8ecb49db1c5a-f30e25e3e10dcfc97f842fb8e6e88a65.jpg)
Initialization check
If you need to check whether the library is initialized, use the GetIsInitialized
method. Method returns a bool
value type:
true
— if the library is initialised;false
— ifInit
has not yet been called.
bool bIsInitialized = URuStoreAppUpdateManager::Instance()->GetIsInitialized();

Проверка наличия обновлений
Before requesting an update, check if it is available for your application To check for updates, call the GetAppUpdateInfo
method. When this method is called, the following conditions will be verified:
- The current version of RuStore is installed on the user's device.
- The user and the app should not be blocked in RuStore.
- RuStore app is allowed to install applications.
- The user is authorized in RuStore.
Upon calling this method, the FURuStoreAppUpdateInfo
object will be returned which contains information regarding any required updates. It is recommended to request and cache this object in advance, ensuring a prompt and convenient update download process for the user.
GetAppUpdateInfo
request returns a requestId
that is unique within a single application run. Each event returns the requestId
of the request that triggered the event.
long requestId = GetAppUpdateInfo(
[](long requestId, TSharedPtr<FURuStoreAppUpdateInfo, ESPMode::ThreadSafe> response) {
// Process response
},
[](long requestId, TSharedPtr<FURuStoreError, ESPMode::ThreadSafe> error) {
// Process error
}
);

The Success
callback notification returns a FURuStoreAppUpdateInfo
structure in the Response
parameter. The structure contains a set of parameters required to determine the update availability.

After the update's availability is confirmed, you can receive the update's download status in OnStateUpdatedInstanceEvent
of the URuStoreAppUpdateManager
object.
DECLARE_DYNAMIC_MULTICAST_DELEGATE_TwoParams(FRuStoreOnStateUpdatedInstanceDelegate, int64, listenerId, FURuStoreInstallState, state);
UPROPERTY(BlueprintAssignable, Category = "RuStore AppUpdate Manager")
FRuStoreOnStateUpdatedInstanceDelegate OnStateUpdatedInstanceEvent;
FScriptDelegate Delegate;
Delegate.BindUFunction(YourUObjectPtr, FName("YourCallbackMethod"));
URuStoreAppUpdateManager::Instance()->OnStateUpdatedInstanceEvent.Add(Delegate);
UFUNCTION()
void YourCallbackMethod(int64 listenerId, FURuStoreInstallState state) {
// Process callback
}
Subscribe to a listener event from Blueprint:

The OnStateUpdatedInstanceEvent
event returns a FURuStoreInstallState
object in the state
parameter describing the current download status. FURuStoreInstallState
is described in Checking the update download status.

The URuStoreAppUpdateManager
class implements a standard listener. You can create your own listener class using the IRuStoreInstallStateUpdateListenerInterface
interface.
UINTERFACE(Blueprintable)
class RUSTOREAPPUPDATE_API URuStoreInstallStateUpdateListenerInterface : public UInterface
{
GENERATED_BODY()
};
class IRuStoreInstallStateUpdateListenerInterface
{
GENERATED_BODY()
public:
UFUNCTION(BlueprintCallable, BlueprintNativeEvent, Category = "RuStore InstallStateUpdate Listener Interface")
void OnStateUpdated(int64 listenerId, FURuStoreInstallState& state);
};
The OnStateUpdated
event returns a FURuStoreInstallState
object in the state
parameter describing the current download status. FURuStoreInstallState
is described in Checking the update download status.
Calling the RegisterListener
method performs registering the listener.
For the default URuStoreAppUpdateManager
listener, calling RegisterListener
is not required.
int64 listenerId = URuStoreAppUpdateManager::Instance()->RegisterListener(YourListenerPtr);
YourListenerPtr
— object of a class that implements IRuStoreInstallStateUpdateListenerInterface

If you no longer need a listener, use the UnregisterListener
method to remove a listener, passing a previously registered listener to the method. UnregisterListener
must be called for all listeners before the application terminates.
For the default URuStoreAppUpdateManager
listener, it is not necessary to call UnregisterListener
on application shutdown.
bool bIsDone = URuStoreAppUpdateManager::Instance()->UnregisterListener(YourListenerPtr);
YourListenerPtr
— object of a class that implements IRuStoreInstallStateUpdateListenerInterface
.
![img](/help/en/assets/images/unreal-UnregisterListener-1219587207aa36300baf8cce9d5d23f3.jpg)
If you implement your own listener, you can also unregister the default listener to save resources.
auto instance = URuStoreAppUpdateManager::Instance();
bool bIsDone = instance->UnregisterListener(instance);
