How to start the PIN code of the android Simulator

Find the sim_card.c file in the external/qemu/telephony/directory of the android source code and change it:

Asimcard asimcard_create (void)

{
......
Card-> Status = a_sim_status_pin; (it should be a_sim_status_ready before modification ).
......

}

Then re-make the source code, after completing the out/host/linux-x86/bin directory of the emulator executable file overwrite the emulator.exe under the android-sdk-linux_86/toolsdirectory

Finally, restart the simulator and verify the PIN code when starting the system.
