Unfortunately (app) has stopped android developer error

Question

I am getting an "unfortunately (app) has stopped" error when I try to run my app on my android phone. The app is supposed to provide an easy interface for controlling a arduino with a bluetooth module Below is my Logcat. Please provide help with this error, I am a first time eclipse user so as many details as possible would be great.

Answer 1

The error message is very specific:

Need BLUETOOTH permission: Neither user 10117 nor current process has android.permission.BLUETOOTH.

You need to declare that permission in your application's manifest.

Answer 2

As chrylis already mentioned, error-message speaks for itself: Need BLUETOOTH permission

Your AndroidManifest.xml should be like this:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.appname" >

<uses-permission android:name="android.permission.BLUETOOTH"/>
<application
    <<<there goes the rest of manifest>>>
