# ONE store Key Management System and the Android App Bundle

### **Can I sell the same app in other markets using the Android App Bundle?** <a href="#onestorekeymanagementsystemandtheandroidappbundle-canisellthesameappinothermarketsusingtheandroidapp" id="onestorekeymanagementsystemandtheandroidappbundle-canisellthesameappinothermarketsusingtheandroidapp"></a>

* Signing keys must match to sell the same app and support updates in other markets.
* You can update it only when you register the signing key created by yourself without using the signing key created by the ONE store or other markets.

### **Can I switch back to APK if I switch the product being sold to AAB?** <a href="#onestorekeymanagementsystemandtheandroidappbundle-caniswitchbacktoapkifiswitchtheproductbeingsoldtoa" id="onestorekeymanagementsystemandtheandroidappbundle-caniswitchbacktoapkifiswitchtheproductbeingsoldtoa"></a>

* Once you switch to AAB, you cannot switch to APK again. Please keep this in mind when deciding to switch to AAB.

### **Can I register an app with the Dynamic Feature Delivery function of the Play Store?** <a href="#onestorekeymanagementsystemandtheandroidappbundle-caniregisteranappwiththedynamicfeaturedeliveryfunc" id="onestorekeymanagementsystemandtheandroidappbundle-caniregisteranappwiththedynamicfeaturedeliveryfunc"></a>

* Yes. However, users can download the product only through Universal APK.

### **Can I register the app with the Asset Delivery function of the Playstore?** <a href="#onestorekeymanagementsystemandtheandroidappbundle-caniregistertheappwiththeassetdeliveryfunctionofth" id="onestorekeymanagementsystemandtheandroidappbundle-caniregistertheappwiththeassetdeliveryfunctionofth"></a>

* Only install-time can be registered among the delivery types of Asset Delivery in the Play Store.

### **I have registered and published multiple APKs. Can I use the key management system?** <a href="#onestorekeymanagementsystemandtheandroidappbundle-ihaveregisteredandpublishedmultipleapks.caniusethe" id="onestorekeymanagementsystemandtheandroidappbundle-ihaveregisteredandpublishedmultipleapks.caniusethe"></a>

* To use the key management system, it must be published as a single binary and not as a multi-binary. Please update the binary to a single binary to use the key management system.

**The verification will be completed after a verification request using the Apply Immediately option, the status will appear as sale pending.**

* As AAB products need time to create a binary that fits the terminal, you may experience a delay. The delay will depend on the file size. However, the process is expected to be completed within 30 minutes.<br>
