How to prevent the installation of an Android application if there is no SDCard?

My code logic requires an SD card installed on the device. I added a check for this case to the application’s splash screen, but I would like to inform users before they download / install this application. Is there any way to achieve this?

Thank!

There is no way to do this before the application is installed, as the only way to limit such things is to use a tag <uses-feature>. However, this tag has no parameters for storage requirements. The best warning you can give is to include it in the description of your application.

  • The unique container in which your application is stored is encrypted with a randomly generated key that can only be decrypted by the device that originally installed it. Thus, the installed application on the SD card only works for one device.
  • The user can move your application to the internal storage through system settings.
