GameMaker: Studio Global Game Settings for Android

This Android tab of the Global Game Settings is split into two separate sub-tabs (accessible on the left of the window) to make changing and updating the information for your game clearer and less complicated. These tabs are explained in the following sections.



The first thing to do is fill in the details about your game, including its Display Name, its Package Name and the Version info. The package name can only be made up of letters from A-Z and numbers 0-9, with no symbols or other special characters at all, nor should it have uppercase characters. It should follow the format“com.domain.myapp”.

To the right of the page, you can add a splash screen to your APK, which will be shown while the game loads on the device. This screen should be a 24bit PNG file, and is recommended to be the same size as the first room (or view) in your game.

On this page you can also set the following options for your final APK file:

  • Architectures - This is the CPU type that your game will support. The most common ones are chosen by default (99% of all devices use these), but you can choose those that you think appropriate. Bear in mind that each one will add about 1MB to the final apk size, don't go ticking them all unless this is not a problem!
  • Orientation - Here you can choose to lock the game to a specific orientation by checking either landscape, portrait, landscape-flipped or portrait-flipped. Note that if you have selected Portrait and Portrait Flipped, then this is handled as sensor Portrait, but not all devices will allow the Portrait Flipped orientation in this mode.
  • Misc - This section permits you to add extra support for certain features:
    • you can add iCade Support or Bluetooth gamepads (see the functions for GamePad Input
    • you can add Haptic Effects which will permit the use of vibration in your game. Haptics are dependant of you accepting the Immersion EULA that pops up. If you decline to accept the agreement, then haptic effects will not be enabled, and if you have code for them in your game, the game will fail to compile. For more information on the GameMaker: Studio haptic effects, see the section in the documentation for Immersion Haptics.
    • if your game is being created for the OUYA games console, then you can specify that the final APK should be packaged in accordance with the console specifications here.
    • you can set the Install Location for your game. This can either be set to auto, in which case the game will be installed to the location chosen by the user on their device, or it can be set to Prefer External which will always try to install the game to the external storage of the device.



The graphics tab has three sections to it - OptionsIcons and Texture Pages. The first of these controls the display options for your game, with the first one being the Interpolate colours Between Pixels flag. This turns on interpolation, which basically "smooths" pixels, so for crisp pixel graphics, it should be off, but if you have nice alpha blends and smoothed edge graphics it is better left on.

Next, you can set the Screen colour Depth to either 16bit or 24bit. This will affect the compatibility with some older devices if it is set to 24bit, and will also increase the ashmem that is needed (this is the shared memory on Android devices).

The next here is the Device Support for your game. You can choose to support any device, or only those that have a GPU. Basically, if your game has any advanced drawing functions like alpha blending, additive blending, surfaces, etc... you should limit it to those devices that have a GPU otherwise you run the risk of getting negative comments and poor rating for your game due to graphical errors or crashes on older devices.

Finally there is the option for scaling to the device screen. Here you can choose to maintain aspect ratio (so a 4:3 room, for example, will be "letter boxed" on a 16:9) or to scale fully (stretching the image to fit the full screen).

WARNING! Switching off the application surface in your code will disable all the scaling options set in the Global Game Settings until it has been switched back on again. See The Application Surface for further details.

After these options there is the section for setting the size of the Texture Page. The default (and most compatible) size is 1024x1024, but you can choose from anywhere between 256x256 up to 2048x2048. There is also a button marked View which will generate the texture pages for this platform and then open a window so that you can see how they look. This can be very useful if you wish to see how the texture pages are structured and to prevent having texture pages larger (or smaller) than necessary.

On the right of the page you can set the game icons. These are used in various situations on the Store and in your Game, and should be creates as 24bit PNG files of the appropriate sizes given.

Note: Be aware that the larger the size of the texture page, the less compatible your game will be.



This tab permits you to enable social functions for your Android game with either Amazon GameCircle or Google Play. Both markets permits you to add achievements and leaderboards for your games in a simple way, allowing worldwide highscores as well as local ones. Once you have ticked the appropriate checkboxes, you will need to code the functionality into your game using the Achievements and Leaderboards functions.

If you are using GameCircle, you can also enable WhisperSync which is an Amazon based cloud storage service (see the section on Cloud Services for more information).

If you use Google Play you will need to add your App Id into this tab for the functions to work (this can be found from your Google Play Developers dashboard).



From this tab you can change some of the permissions that your game may request within the Android ManifestGameMaker: Studio allocate permissions automatically as required, however you may find you require a permission for your game that we haven't assigned in which case tick the requisite permission box on the tab. The list below outlines those that are available:

  • WRITE_EXTERNAL_STORAGE - Will permit your game to write to external storage.
  • READ_PHONE_STATE - Allow read only access to the phone state.
  • ACCESS_NETWORK_STATE - Permit your game to access information about networks.
  • INTERNET - Permit your game to open network sockets.
  • BLUETOOTH - Will permit your game to connect to paired Bluetooth devices.
  • RECORD_AUDIO - Will permit you to record audio

NOTE: If you are not sure that you need these, you should probably just leave them un-checked by default and let GameMaker: Studio deal with the permissions for your game.
