Publish to Google Play Instant

Starting with Cocos Creator v2.0.4, creating games for the Google Play Instant is officially supported. Google Play Instant relies on Google Play, and it is not a new distribution channel, but closer to a game micro-end solution.

It can realize the game to be played without installing, which is useful for game's trial play, sharing and conversion. The main differences between Google Play Instant and the Android Instant App are:

  • Both the first package and the APK add-on are limited to 10MB (instead of 4MB)
  • Dynamically load resources without binary code from third-party CDN (JS is also available)
  • APK add-on packages can only be downloaded from the Google Play Store, can contain binary code and resources, can be loaded in the background, do not need to switch activity

With games developed by Cocos Creator, just choose Google Play Instant as the publishing platform, which can automatically complete the standard adaptation work. Developers can quickly publish games that meet the Google Play Instant technical standards

Using Cocos Creator publish to Google Play Instant with one click


  • Android Studio 3.0+
  • Android Phone 6.0+
    Attention: Devices with Android SDK version between 6.0 and 7.0 need to install Google Service Framework. And Android 8.0 or higher does not need.
  • The recommended NDK version is r17 - r19.

Instant Games Publish Process

  1. Using Cocos Creator open the project that needs to be published. Open the Build panel from the Menu bar. Select Android Instant in the platform of the Build panel, choose android-instant in the template, and the API Level selects android-26 and above.

  2. If you want to package directly without using the refactor feature, you can hook the Skip Record & Refactor box, then click Build -> Compile, connect android phone to the computer and then click the Play button, when process complete you can run Google Play Instant on the phone.

    If you compile for the first time, you need to open the post-built project with Android Studio to download Google Play Instant Development SDK (windows platform) Support package, Mac platform is the Instant Apps Development SDK support package. If the download fails, it is recommended to set up an HTTP proxy for Android Studio.

  3. If you need refactor, you can click the Record button in the build panel, and simulator will be opened. The simulator will automatically record the resources used. What we need to do is to play the game according to the game flow and let the simulator record resources information.

  4. After the recording is completed, click Refactor, and the Refactor panel will be opened to complete the refactor operation. For specific refactor steps, please refer to Refactor.

  5. After the refactor is complete, select the Record config path -> ... in the Build panel. This step will open the profiles folder to select the path where the refactor record is located (Refactor records are saved in the path_to_your_project/temp/android-instant-games/profiles directory). We can delete unwanted refactor records by deleting the corresponding folder.

  6. Clicking Build in the Build panel will use the refactor record to split the first package. Then click Compile -> Play and make sure the phone is on the same LAN as the PC, and you can test the Google Play Instant running.

    If you have already run a game, to run the new project again, you need to close the previous game process on your phone, otherwise the new project will not run on the phone because the port is occupied.

The main configuration notes in the Build panel about publishing to Google Play Instant are as follows:

  • Server Address: The download address of the remote resource, can be a CDN address. Put the build/android-instant/remote_res folder into the server or CDN, Cocos Creator will go to this address to download the resources that are not in the first package.
  • Default URL: Android will load your instant app by this URL. This parameter can be empty, if it is not empty, you must ensure that the URL entered is accessible when submitting the package to the Google Store. See Google Instant App documentation for details.
  • Record config path: Cocos Creator will use this record config to generate first package and remote_res folder.

Attention: If the Google Play Instant package has more permissions than the app on Google Store, it may not install properly when you install the app:


The Refactor is used to edit the first package of the game and select the resources to be placed into the first package.


  1. When you finish the Record, Click Refactor to open Refactor panel.

  2. The Refactor opens the latest record by default. If you need to open another record, you can click + Open record. The Refactor can also open multiple records at the same time for comparison.

  3. Drag the end point, you can choose to divide the resources into the first package. When you drag the end point, you can find the data of the file list and the total size and other data changes. Select the size of the first package suitable for the game and we can finish the first step of the record.

  4. Refactor can adjust all resources, on the page of the file list, expand the nodes of each category, and we can see the size of each file, we can remove the resource by uncheck the resource item.

  5. If some resources are not in the first package, but we want to put it in the first package, we can click the + Manual button to open the Manual panel, the rest of the resources will be presented here. Check the resources that you need to put into the first package and tick the resource, then click the Add button, you will find that it has been added to the Refactor panel.

  6. If you need to add other resources to the first package, you can also select resources from the Assets panel and drag them into the Refactor panel.

  7. Finally, click Save button to save the first package info into record.

  8. In the Record config path option of the Build panel, select the record we just edited, and then click the Build button, Cocos Creator will use this record to generate the first package and other resources.
