| 17 | # Android Technical Information # |
| 18 | Welcome to the Android technical documentation section of the site. Here you |
| 19 | can find technical information useful to people and organizations who are |
| 20 | looking to modify, contribute to, or port the Android software. This is "under |
| 21 | the hood" information intended for engineers. |
| 22 | |
| 23 | ## Dalvik Technical Information ## |
| 24 | The Dalvik Virtual Machine is the heart of Android. It's a fast, just-in-time |
| 25 | compiled, optimized bytecode virtual machine. Android applications are |
| 26 | compiled to Dalvik bytecode and run on the Dalvik VM. This section includes |
| 27 | detailed information such as the Dalvik bytecode format specification, |
| 28 | design information on the VM itself, and so on. |

| 33 | ## Bluetooth Technical Information ## |
| 34 | The Android Open-Source Project includes a bluetooth subsystem currently based |
| 35 | on the upstream bluez project. Android then layers various IPC and similar |
| 36 | libraries to link the bluez library with the Android Bluetooth stack and API. |

| 41 | ## NFC Technical Information ## |
| 42 | The Android Open-Source Project also includes an NFC implementation. Unlike |
| 43 | the Android Bluetooth stack, much of the Android NFC stack is new code |
| 44 | originally contributed to the Android Open-Source Project. This code links the |
| 45 | Android NFC API to a device's NFC hardware. This section also includes |
| 46 | information on related Android technologies, such as the simple NDEF Push |
| 47 | Protocol. |

| 52 | The Android Open-Source Project includes the ability to encrypt the user's data. |
| 53 | This document is written for 3rd parties developing Android devices who want to |
| 54 | include support for encryption on their device. It covers the few things that |
| 55 | must be done so encryption will work. |
