1、预装 app

一般就三种情况，预装不可卸载，预装可卸载恢复出厂恢复，预装可卸载恢复出厂不能恢复

可参考内置apk

1.1、预装不可卸载

这种情况 app 最终位于 system/app 或 system/priv-app 即可，作为系统应用，不可卸载

Android.mk 中不配置输出路径则默认打包到 system/app

要想打包到 system/priv-app 则配置 LOCAL_PRIVILEGED_MODULE := true

1.2、预装可卸载恢复出厂恢复

这种情况就比较特殊了，不同的厂商会有自己的方法。

MTK 将 app 依旧作为系统 app，增加了一个包名清单可配置要卸载的系统应用，

这样就确保了能卸载，恢复出厂系统应用又能自动恢复。

RK 也是将 app 作为系统 app，通过放置到特殊文件夹确保可卸载，卸载时会将包名写入缓存文件，

恢复出厂系统会读取缓存文件判断是否需要安装对应 app。

SQRD 也有自己的方法，将 app 打包到 system/vital-app 或 system/preloadapp 即可

这两个目录区别如下

preloadapp 目录中的应用在开机的过程是异步安装的（有利于加快开机速度），存在开机后在 home 界面，

该目录下的应用一个个显示出来的现象。如果是开机急于使用的应用，

例如说在 Launcher 上配置了文件夹存放第三方应用，建议放在 vital-app 目录中，如果不要求开机即使用，建议存放在 preloadapp 目录。

vital-app 目录中的应用在开机的过程中是同步安装的，开机后不会出现上述 preloadapp 下应用一个个出现的现象，

但是会造成开机时间相应变长。一般需要开机进入待机就要安装好的应用（如输入法应用）才建议预置到该目录。

Android.mk 中增加配置

LOCAL_MODULE_PATH := $(TARGET_OUT)/preloadapp

LOCAL_MODULE_PATH := $(TARGET_OUT)/vital-app

1.3、预装可卸载恢复出厂不能恢复

这种情况一般都是将 app 打包到 data/app 目录即可

Android.mk 中增加配置

LOCAL_MODULE_PATH := $(TARGET_OUT_DATA_APPS)

10.0 存在 bug data/app 中放置了 apk，烧写后系统不能正常启动，会自动进入 recovery 界面，提示需要清除 usedata 数据

也就是 data/app 下的 apk。解决办法 androidQ(10.0) 预装集成apk到data分区

2、系统主题风格切换

apk 中有很多资源文件，包括应用图标和名称。国产手机在系统主题切换这块做的很顶，网上思路很多，这里用一种偷懒的办法单机版本。

aosp 本身 app 图标和名称是非常丑的，这就需要我们给它美化一番。

2.1、获取这些 app 包名

按个点击进入这些 app，依次执行 adb shell dumpsys window | findstr mCurrentFocus 获取包名

2.2、自己搜罗一套精美 icon

2.3、开始替换之旅

替换图标

将 icon 资源文件 copy 至 frameworks/base/core/res/res/drawable-xhdpi/

配置 icon 为 drawable 资源

frameworks/base/core/res/res/values/symbols.xml

+  <!-- //20210323 cczheng add for  Chromium icon S -->
+  <java-symbol type="drawable" name="ic_app_deskclock" />
+  <java-symbol type="drawable" name="ic_app_settings" />

+  <java-symbol type="drawable" name="ic_app_vedio" />
+  <java-symbol type="drawable" name="ic_app_email" />
+  <!-- end --><java-symbol type="drawable" name="default_wallpaper" />

6、解锁 OEM 方法

展讯设备解锁需要在 linux 环境下执行相关指令

sudo apt-get install android-tools-adb
sudo apt-get install android-tools-fastboot

1、虚拟机-可移动设备-选中手机从主机切换为虚拟机

2、adb devices 显示 no permissions
lsusb 获取设备 vid 和 pid

sudo vim /etc/udev/rules.d/51-android.rules 没有这个文件就自己新建一个

SUBSYSTEM==“usb”,ATTRS{idVendor}“vid”,ATTRS{idProduct}“pid”,MODE=“0666”

sudo chmod a+rx /etc/udev/rules.d/51-vboxadd.rules

3、重新插拔设备，齐活

环境搞定了，接下来整理需要的几个关键文件

将下面三个文件 copy 到新建文件夹中

signidentifier_unlockbootloader.sh
rsa4096_vbmeta.pem
fastboot

vendor\sprd\proprietories-source\packimage_scripts\signidentifier_unlockbootloader.sh
vendor\sprd\proprietories-source\packimage_scripts\signimage\sprd\config\rsa4096_vbmeta.pem

4、开始解锁

4.1、获取设备 Product SN 序列号
a、设备开机后连接ubuntu电脑，执行adb reboot bootloader，将设备启动到fastboot模式。
b、通过下面的命令获取SN序列号

$ sudo ./fastboot oem get_identifier_token
(bootloader) Identifier token:

(bootloader) 3631313536383435303133303839
3538383432353430353737363239
OKAY [ 0.018s]
Finished. Total time: 0.018s

4.2、生成解锁凭证certificate.bin
Linux 环境下使用完整 SN 序列号生成证书（certificate.bin）。

生成证书的命令
$./signidentifier_unlockbootloader.sh 3631313536383435303133303839 rsa4096_vbmeta.pem certificate.bin

4.3、使用证书 certificate.bin 解锁

a、设备开机后连接ubuntu电脑，执行adb reboot bootloader，将设备启动到fastboot模式。
b、ubuntu电脑上执行如下的解锁指令

$ sudo ./fastboot flashing unlock_bootloader certificate.bin
[sudo] password for liuyg:
Sending ‘unlock_message’ (0 KB) OKAY [ 0.000s]
unlocking bootloader OKAY [ 59.671s]
Finished. Total time: 59.671s

c、按设备音量-键确认

4.4、完成
重启设备后，引导加载程序会先检查设备状态是 LOCKED 还是 UNLOCKED。
如果设备状态是UNLOCKED，设备在开机第一帧 Logo 界面左上角会显示：
“INFO： LOCK FLAG IS : UNLOCK!!!”
“WARNING: LOCK FLAG IS : UNLOCK, SKIP VERIFY!!! ”

7、状态栏左上角显示运营商信息

frameworks\base\packages\SystemUI\res\values\config.xml

<!-- Whether to show operator name in the status bar -->
<bool name="config_showOperatorNameInStatusBar">true</bool>

以前都是自己加一个在状态栏右边的，现在发现源码中其实已经自带了，打开这个配置就行

CollapsedStatusBarFragment.java --> initOperatorName() OperatorNameView.java

8、状态栏右边增加 SIM 未插入图标

9、Launcher3 去除 HotSeat 栏

packages\apps\Launcher3\src\com\android\launcher3\DeviceProfile.java

 hotseatBarSizePx = ResourceUtils.pxFromDp(inv.iconSize, dm) + (isVerticalBarLayout()? (hotseatBarSidePaddingStartPx + hotseatBarSidePaddingEndPx): (res.getDimensionPixelSize(R.dimen.dynamic_grid_hotseat_extra_vertical_size)+ hotseatBarTopPaddingPx + hotseatBarBottomPaddingPx));android.util.Log.d("DeviceProfile","1   hotseatBarSizePx="+hotseatBarSizePx);

+  float hotseatCellWidth = 0;//(float) widthPx / inv.numHotseatIcons;int hotseatAdjustment = Math.round((workspaceCellWidth - hotseatCellWidth) / 2);mHotseatPadding.set(hotseatAdjustment + workspacePadding.left + cellLayoutPaddingLeftRightPx,hotseatBarTopPaddingPx,hotseatAdjustment + workspacePadding.right + cellLayoutPaddingLeftRightPx,hotseatBarBottomPaddingPx + mInsets.bottom + cellLayoutBottomPaddingPx);

11、去除 Launcher 图标右上角未读消息小圆点提示

Settings.Secure.putInt(getContentResolver(), Settings.Secure.NOTIFICATION_BADGING, 0);

12、WIFI 已连接，但无法访问互联网

展讯自己把 CAPTIVE_PORTAL_MODE 默认值修改为0了，所以当你真正连接到没有物联网的wifi时，不会提示无法访问互联网。

注释这个 CAPTIVE_PORTAL_MODE 默认赋值就行

adb shell settings get global captive_portal_mode

0：彻底禁用检测
1：检测到需要登录则弹窗提醒
2：检测到需要登录则自动断开此热点并不再自动连接

frameworks/base/packages/SettingsProvider/src/com/android/providers/settings/DatabaseHelper.java

  //loadIntegerSetting(stmt, Settings.Global.CAPTIVE_PORTAL_MODE,//       R.integer.captive_portal_mode);

这个放开后，wifi 连接后会有校验，真正能上网的wifi也会提示无法访问互联网

将下面校验网址改成国内可以访问到的即可

packages/modules/NetworkStack/res/values/config.xml

    <!-- HTTP URL for network validation, to use for detecting captive portals. --><string name="default_captive_portal_http_url" translatable="false">http://www.googleapis.cn/generate_204</string><!-- HTTPS URL for network validation, to use for confirming internet connectivity. --><string name="default_captive_portal_https_url" translatable="false">http://www.googleapis.cn/generate_204</string>

去除展讯自己加的wifi连接成功后网络主界面多增当前连接Preference

packages/apps/Settings/src/com/android/settings/network/MultiNetworkHeaderController.java

 @Overridepublic int getAvailabilityStatus() {return CONDITIONALLY_UNAVAILABLE;}
