LogCat output debugging help

My Logcat output for my program failing. It apparently can't access some kind of SD card, but I'm using the emulator. I'm on x64 windows 7, and I ran as administrator.

In FileHandle.java in your code you're trying to write something to the SD card (line 153). The error "Permission Denied", therefore I assume you didn't add the correct permission to your AndroidManifest.xml. Add:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

And it should be ok. Make sure you have an SD card configured in the emulator (using the AVD)
