支持開(kāi)源鴻蒙/Linux /Andriod 11/麒麟，兼容樹(shù)莓派 ;

四核A55，最高1.8G主頻，Mali G52-2EE GPU ;

支持OpenGL/CL/Vulkan/1T NPU/8M ISP ;

支持TensorFlow/MXNet/PyTorch/ Caffe ;

支持1*千兆以太網(wǎng)、3*USB2.0、1*USB3.0、3*UART、2*SPI、2*I2C、28*GPIO、1*MIPI DSI、1*HDMI ;

支持OpenHarmony3.2/4.0/4.1版本，開(kāi)放SDK源代碼 ;

活躍的開(kāi)發(fā)者社區(qū)， 更多牛人在線技術(shù)支持 ;

超小尺寸，極致性?xún)r(jià)比，只需249元 ;

一、APP自啟

1.1 添加自啟服務(wù)

修改文件：

frameworks\base\core\java\com\android\internal\app\ResolverActivity.java

1.2 添加APP

將需要自啟的APP放置
device/rockchip/rk356x/rk3566_r/preinstall_del/目錄下

（沒(méi)有preinstall_del目錄就手動(dòng)創(chuàng)建一個(gè)即可），并添加以下文件：

Android.mk

xxx.apk（APP）

preinstall.mk

Android.mk文件內(nèi)容：

include $(call all-subdir-makefiles)
preinstall.mk文件內(nèi)容：

PRODUCT_PACKAGES += neu

注意：

neu為APP名字，例如neu.apk。

該目錄也是APK的預(yù)安裝目錄，如果有新的APK要預(yù)安裝，可把APK拷貝到preinstall_del/目錄下，并且把APK名字添加到preinstall.mk文件即可。

1.3 添加APP包名

修改文件：
device/rockchip/rk356x/rk3566_r/rk3566_r.mk
例如包名為：
com.mdptech.neuronappandroidhu

--- a/device/rockchip/rk356x/rk3566_r/rk3566_r.mk +++ b/device/rockchip/rk356x/rk3566_r/rk3566_r.mk @@ -46,4 +46,5 @@ PRODUCT_PROPERTY_OVERRIDES += persist.bt.power.down=true PRODUCT_PROPERTY_OVERRIDES += persist.sys.timezone=Asia/Shanghai PRODUCT_PROPERTY_OVERRIDES += ro.vendor.hdmirotationlock=true #PRODUCT_PROPERTY_OVERRIDES += vendor.hwc.device.primary=HDMI-A-1 PRODUCT_PROPERTY_OVERRIDES += vendor.hwc.device.primary=DSI +PRODUCT_PROPERTY_OVERRIDES += persist.sys.def_launherpag=com.mdptech.neuronappandroidhu

包名命令行方式查看：pm list package -3，修改后 make 編譯源碼即可。

二、修改導(dǎo)航欄/狀態(tài)欄

2.1 導(dǎo)航欄

修改文件：

frameworks/base/packages/SystemUI/res/layout/navigation_bar.xml

--- a/frameworks/base/packages/SystemUI/res/layout/navigation_bar.xml +++ b/frameworks/base/packages/SystemUI/res/layout/navigation_bar.xml @@ -22,6 +22,7 @@ xmlns:systemui="http://schemas.android.com/apk/res-auto" android:layout_height="match_parent" android:layout_width="match_parent" + android:visibility="gone" android:background="@drawable/system_bar_background"> + android:layout_height="match_parent" + android:visibility="gone"/>

2.2 狀態(tài)欄

修改文件：

frameworks/base/packages/SystemUI/res/layout/status_bar.xml

--- a/frameworks/base/packages/SystemUI/res/layout/status_bar.xml +++ b/frameworks/base/packages/SystemUI/res/layout/status_bar.xml @@ -26,6 +26,7 @@ android:id="@+id/status_bar" android:orientation="vertical" android:focusable="false" + android:visibility="gone" android:descendantFocusability="afterDescendants" android:accessibilityPaneTitle="@string/status_bar" >

修改后重新make編譯即可。
