In the below attached code , I am able to select file from internal storage using file picker, but unable to open the file for reading the file. code for reading the file is written, looks like its not picking the right path for opening the file, so throwing exception. Can anyone help me diagnose the issue.

You didn't attach anything. You could also just post a snippet:
[code]in.read(buf);[/code]

The problem is that your intent.getData() is returning a content URI, not a file URI. There is no path.
https://developer.android.com/reference/android/content/Intent#ACTION_GET_CONTENT
https://developer.android.com/reference/android/content/ContentResolver#openInputStream(android.net.Uri)
Java:
Uri uri = intent.getData();
ContentResolver cr = getContentResolver();
InputStream in = cr.openInputStream(uri);

Thank you so much for your help now code is working

I have currently created a simple tcp socket client application that sends and receives messages from a dotnet server application I have created. The application itself actually works however there are a few things I would like to know if they are possible or not. Also this is my first ever droid application and my first ever java application so I am sure there is a better way to do what I have written so please go easy on me.
The problem that I am having is I need a way to monitor the status of the socket so that if the connection gets dropped whether it is from the server application ending or a network drop that the android client would disconnect and put a notification on the screen letting me know. Currently if I end the server application nothign happens on the client and it acts like the connection is still open. Granted this is probably due to the way I have it written so I am looking for samples or suggestions on how to change this so I can monitor this. Any help would be great. Eventually this will be put into a much larger project for my home but I am starting off small so I can do it correctly the first time rather than having someing messy later on.
My code is listed below.
Thanks
KJ

So what is exactly the point of this thread?
I am trying to make an app that on launch reads the current on/off(1,0) value of /sys/class/mdnie/mdnie/negative, then changes it to "0 or 1. Someone suggested the below, and I tried it and it does nothing any help is apreciated. Obvously I am a beginner and barely know how to write code but hey gotta start somewhere, this is for a visually impaired friend to toggle negative color mode by assigning a shortcut key to the app. I think it has to do with needing root permision to edit those settings.

if ("1".equals(value.trim())) {
writeStringToFile(FILEPATH, "0");
}
else {
writeStringToFile(FILEPATH, "1");
}}
