I have tried to remove the particular application ,but it not removing that application and sometimes it is disconnecting in that situation .
How did you do that?
Does the log show any errors while you are trying to remove the app?
I have run in to this problem a lot.
For me the log would always show something along the lines of “no such path /foo/bar”
The only way I could stop the error from occurring was to run my app unsandboxed. That might not be a solution for you, but it might be worth trying to see if it fixes it for you.
For removing the application you can use :
app remove “application”
There is an alternative way with update-pack tool to remove an application in the target from your Linux host, example :
update-pack -ar helloWorld -o helloWorld.remove.update
After that you flash the target with helloWorld.remove.update
