1 Work with Android 8.1
FriendlyElec provides a full Android8.1 BSP for {{{1}}}. The source code is hosted at gitlab.com and is open source. The BSP supports GPU and VPU hardware acceleration.
1.1 Connect MIPI Camera to {{{1}}}
FriendlyElec developed a MIPI camera CAM1320 for board and it works under Android. You can use this camera to take pictures and record video. The operation is straightforward. You just need to connect the camera at your board's MIPI interface, boot your board to Android and start Android's camera app.
1.2 Android8.1 hardware access
You can use the FriendlyThings SDK to access and control hardware resources on the motherboard in the Android App, such as Uart, SPI, I2C, GPIO and other interfaces. For details, please refer to the following two documents.：
1.3 Android Neural Networks SDK Sample
Android8.1 BSP comes pre-installed with Rockchip's Android NN SDK for Android 8.1, supporting GPU acceleration.。
Sample program for Android NN pre-installed in the Android8 firmware we provide：TfLiteCameraDemo，This is a MobileNet classifier demo using Rockchip AndroidNN GPU acceleration，The camera module is required to be connected to the motherboard during operation. The USB camera and CSI camera are supported，The sample program is launched by clicking the "TfLiteCameraDemo" icon on the home page. The running effect is as follows：
For a detailed description of the Android NN SDK, you can refer to this document：[RK3399_Android8.1_AndroidNN_SDK_V1.0_20180605发布说明.pdf]

1.4 Using the adb
1. The first time you start the system, if you need to change the system files, you need to turn off security verification (note: apk installation does not need to be closed), and restart after turning off security verification
adb root adb disable-verity adb reboot
