内置第三方apk总结

本篇集中说明第三方应用集成 写法，以及怎么集成可卸载第三方应用。

写法

签名

1. 自签名

android_app_import {
    name: "SogouInput",
    system_ext_specific: true,
    presigned: true,
    dex_preopt: {
        enabled: false,
    },
    apk: "SogouInput_android_oem_baoneng.apk",
}

2. 系统签名

# system signal
android_app_import {
    name: "SogouInput",
    system_ext_specific: true,
    certificate: "platform",
    apk: "SogouInput_android_oem_baoneng.apk",
}

集成位置

1. system/app

android_app_import {
    name: "SogouInput",
    presigned: true,
    dex_preopt: {
        enabled: false,
    },
    apk: "SogouInput_android_oem_baoneng.apk",
}

2. system_ext/app

android_app_import {
    name: "SogouInput",
    system_ext_specific: true,
    presigned: true,
    dex_preopt: {
        enabled: false,
    },
    apk: "SogouInput_android_oem_baoneng.apk",
}

3. system/pri-app

必须声明在permission白名单内。
aosp路径：frameworks/base/data/etc/
手机路径：system/etc/permission/

android_app_import {
    name: "SogouInput",
    privileged: true,
    presigned: true,
    dex_preopt: {
        enabled: false,
    },
    apk: "SogouInput_android_oem_baoneng.apk",
}

4. product/app

android_app_import {
    name: "SogouInput",
    product_specific: true,
    presigned: true,
    dex_preopt: {
        enabled: false,
    },
    apk: "SogouInput_android_oem_baoneng.apk",
}

5. vendor/app

android_app_import {
    name: "SogouInput",
    proprietary: true,
    presigned: true,
    dex_preopt: {
        enabled: false,
    },
    apk: "SogouInput_android_oem_baoneng.apk",
}

第三方可卸载apk集成方法

1. MTK 平台方案

• 将包名添加到配置文件（vendor\mediatek\proprietary\frameworks\base\data\etc\pms_sysapp_removable_system_list.txt）
• mk文件完成拷贝

// device/mediatek/common/
 ifneq ($(strip $(MTK_BASIC_PACKAGE)), yes)
+  PRODUCT_COPY_FILES += $(call add-to-product-copy-files-if-exists,vendor/mediatek/proprietary/frameworks/base/data/etc/pms_sysapp_grant_permission_list.txt:system/etc/permissions/pms_sysapp_grant_permission_list.txt)
   PRODUCT_COPY_FILES += $(call add-to-product-copy-files-if-exists,vendor/mediatek/proprietary/frameworks/base/data/etc/pms_sysapp_removable_system_list.txt:system/etc/permissions/pms_sysapp_removable_system_list.txt)
   PRODUCT_COPY_FILES += $(call add-to-product-copy-files-if-exists,vendor/mediatek/proprietary/frameworks/base/data/etc/pms_sysapp_removable_vendor_list.txt:$(TARGET_COPY_OUT_VENDOR)/etc/permissions/pms_sysapp_removable_vendor_list.txt)
 endif

• 源码分析

// PMS中添加
if ((pkg, updatedPkg, ps, scanFile))
    return null;
//()
//MtkSystemServiceFactoryImpl (vendor/mediatak/proprietary/frameworkes/base/.../)
// (vendor/mediatak/proprietary/frameworkes/base/.../)
 @Override
    public boolean needSkipScanning( pkg,
            PackageSetting updatedPkg, PackageSetting ps, File scanFile) {
       if (!() &&
           (isRemovableSysApp() || locationIsOperator(scanFile)) &&
           (ps == null && updatedPkg == null)) {
            if (()) {
                if (isRemovableSysApp()
                        && !()) {
                    (TAG, "New added removable sys app by OTA:" + );
                    return false;
                }
                if (locationIsOperator(scanFile)
                        && ()
                        && !()) {
                    (TAG, "New added operator app by OTA:" + );
                    return false;
                }
            }
           (TAG, "Skip scanning uninstalled sys package " + );
           return true;
       } else if (ps == null && updatedPkg != null) {
           (TAG, "Skip scanning uninstalled package: " + );
           return true;
       }
 
       return false;
    }
