Answer 1

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)
