Stories similar to Android Bluetooth as client i cant connect with my arduino

I am quite new to java and currently working on a project. I have managed to turn on and off bluetooth from within my app. I also have a list view with a list of paired devices. I have created an "onListItemClick" method. However,I can't seem to figure out how to establish a connection with one of the paired devices. Any help would be appreciated.

I have a simple socket server running on my PC and I made a client for the pc to talk to itself however I wanted to adapt it for Android but it keeps crashing telling me something is wrong in the closeChat() method but I cannot figure out what.

I am trying to establish a chatting application between a server and a client, but the application could not run because of this line of code : message = (String) input.readObject(); because at first, inputStream is null ! any one can help please ?

I am new to java and currently working on a project. I am trying to get familiar with the bluetooth. So far, i have been able to turn on and off bluetooth from within the app. The problem i have is that the screen does not refresh after an action has been carried out. For example, when i turn on the bluetooth, it comes on, but the text in the textview doesn't update until i flip the phone over.

The code works fine in java console but when in android emulator it gives an error.
