Android常用系统定制

H618 Android 12.0 为官方 tv 系统，兼容 tv 版本的 APP，安装使用 tablet 或 phone 版本的 APP 可能会存在兼容性问题。

屏幕方向与旋转

ADB命令旋转屏幕

支持使用adb命令进行旋转

// 正常显示
adb shell settings put system user_rotation 0

// 90°
adb shell settings put system user_rotation 1

// 180°
adb shell settings put system user_rotation 2

// 270°
adb shell settings put system user_rotation 3

软件默认修改显示方向

(SDK)$ vim android/device/softwinner/ceres-c3/ceres_c3.mk

    #ro.surface_flinger.primary_display_orientation=ORIENTATION_90
    #ro.surface_flinger.primary_display_orientation=ORIENTATION_270

支持 ORIENTATION_0、ORIENTATION_90、ORIENTATION_180、ORIENTATION_270

示例：修改屏幕默认显示旋转90°

(SDK)$ vim android/device/softwinner/ceres-c3/ceres_c3.mk

PRODUCT_PROPERTY_OVERRIDES += \
- ro.surface_flinger.primary_display_orientation=ORIENTATION_0
+ ro.surface_flinger.primary_display_orientation=ORIENTATION_90

开机LOGO

开机动画

支持 bootanimation.mp4 以及 bootanimation.zip 两种文件格式的开机动画

已知问题：mp4格式开机动画系统第一次上电启动会显示安卓开机动画

两种文件同时存在播放 mp4 优先级比 zip 高，具体优先级见 frameworks/base/cmds/bootanimation/BootAnimation.cpp

第一步，存放动画文件（zip 或 mp4 格式）

device/softwinner/apollo/common/media/bootanimation/bootanimation.zip
device/softwinner/apollo/common/media/bootanimation/bootanimation.mp4

第二步，修改编译配置

bootanimation.zip 格式

PRODUCT_COPY_FILES += \
-		$(BOOTANIMATION_CONFIG_PATH)/bootanimation.mp4:system/media/bootanimation.mp4

        return out;

    // construct a locale value from the individual locale components.

    const std::string productRegion = GetProperty("ro.product.locale.region", "US");

    return productLanguage + "-" + productRegion;
}

预装APP

示例：新增 test.apk

第一步，新增目录 testapk 在 h618-android12.0\vendor\aw\public\prebuild\ 下。

第二步，存放 test.apk 和 Android.mk（或Android.bp）文件；

$ ls vendor/aw/public/prebuild/testapk
test.apk
Android.mk (Android.bp)

Android.mk

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)

LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)

LOCAL_CERTIFICATE := PRESIGNED

LOCAL_ENFORCE_USES_LIBRARIES := false
LOCAL_DEX_PREOPT := false

LOCAL_MODULE := test

LOCAL_SRC_FILES := $(LOCAL_MODULE).apk

include $(BUILD_PREBUILT)

LOCAL_CERTIFICATE 支持 testkey、platform（系统签名）、shared、media、PRESIGNED（保留原签名）
LOCAL_MODULE 模块名称
LOCAL_SRC_FILES 模块源码路径

Android.bp

android_app_import {
    name: "test",
    apk: "test.apk",

    presigned: true,
    //certificate: "platform", 
    dex_preopt: {
        enabled: true,
    },

    privileged: true,
    //product_specific: true,
    //proprietary: true,
    enforce_uses_libs: false,
}

name 模块名称
apk 模块源码路径

第三步，添加模块编译（对应模块名称）

$ vim /vendor/aw/homlet/homlet.mk
+ PRODUCT_PACKAGES += \
+       test

APK签名

如果需要给APK签名，查看 Android_Apk_Signing 文档。

kickpi-book/common/en/android/Android_Apk_Signing.md
kickpi-book/common/zh/android/Android_Apk_Signing.md

ADB 功能

adb连接

板卡使用type-c线连接电脑，等板卡蓝灯闪烁时查看系统设备管理器是否识到是安卓设备，如果识别到的设备如图所示则需手动安装驱动

手动安装驱动

win键+R打开“运行” 输入cmd打开命令行

命令行中输入adb shell即可连接

系统若没有adb命令支持可自行参考安装Windows 10 安装 ADB (Android Debug Bridge，Android 调试桥)-CSDN博客

adb offline 问题

$ adb devices
List of devices attached
6c00107150d147e1d52     offline

reconnect 即可

$ adb reconnect
reconnecting 6c00107150d147e1d52 [offline]

网络ADB

网口ADB需要先adb启动5555端口服务后

PS C:\Users\16708\Desktop> adb tcpip 5555
PS C:\Users\16708\Desktop> adb connect 192.168.77.170
connected to 192.168.77.170:5555
PS C:\Users\16708\Desktop> adb devices
List of devices attached
7c001075a313c7c1c12     device

PS C:\Users\16708\Desktop> adb -s 192.168.77.170:5555 shell
apollo-p2:/ $ su

开机默认启动5555端口

需要通过USB adb操作

 adb root
 adb remount
 adb pull /system/build.prop
 //在build.prop中加入
 //添加这一行
 service.adb.tcp.port=5555
 //替换进入
 adb push .\build.prop /system/build.prop
 adb reboot

常见问题

APP特殊权限问题

若APP为特殊应用（system-app 或 priv-app），如果没有相关权限，会出现系统无法起来问题，需要抓取 APP 相关 log 日志

# logcat | grep com.example.myapplication3
09-14 10:36:06.662  3826  3826 W PackageManager: Privileged permission android.permission.INSTALL_PACKAGES for package com.example.myapplication3 (/system/priv-app/LauncherJingWei) not in privapp-permissions allowlist
09-14 10:36:08.437  3826  3826 W PackageManager: Privileged permission android.permission.INSTALL_PACKAGES for package com.example.myapplication3 (/system/priv-app/LauncherJingWei) not in privapp-permissions allowlist

com.example.myapplication3 为（Androidapk的包名）
android.permission.INSTALL_PACKAGES 为预装APP缺少的权限

方式一

修改源码，根据 log 中的 android.permission.INSTALL_PACKAGES 报错添加对应 APP 的权限允许，其他报错类似：
