I made applicaton for linux system which opens port and read/write is working fine.

Same App i compiled for Android armV7 and deployed apk in android device,

 while opening port it is giving error: "Permission denied"
(here it needs root permission to "ttyACM0" file)

what can be solution??

On Android direct access to hardware is forbidden. You ned to look into Android APIs and possibly JNI.
