When trying to install an application signed using system signature on device throws [INSTALL_FAILED_SHARED_USER_INCOMPATIBLE] exception while it is getting installed properly in emulator. I have signed it following steps from How can I sign my application with the system signature key?

Please help me know how i can install it into device without rooting the device.

I have to publish the app and if it works only on rooted how can I go with it, please correct me if i am wrong.

  1. You cannot install apps that require system permissions without them being signed with a system signature.
  2. You cannot install apps with a system signature on an unrooted device.
