如果用户更改设备或再次安装应用程序时，async存储值要持续下去怎么办？

您不会相信它，但是它可以与Android一起使用！

首先，我们需要在android/app/src/main/AndroidManifest.xml文件中启用备份选项：

    <application
      android:allowBackup="true"
      android:dataExtractionRules="@xml/backup_rules"

文档：koude1

然后创建具有应添加到备份的文件列表的android/app/src/main/res/xml/backup_rules.xml文件：

<?xml version="1.0" encoding="utf-8"?>
<data-extraction-rules>
  <cloud-backup>
    <!-- your rules -->
  </cloud-backup>
  <device-transfer>
    <!-- your rules -->
  </device-transfer>
</data-extraction-rules>

文档：Backup and restore

测试

下面列出了更多规则，但首先，让我们看一下如何测试它们。

  1. 您可以使用模拟器或真实设备
  2. 需要启用备份：Setting => System => Backup5
  3. 然后使用adb您可以创建/还原备份： 
# Replace `com.mycompany.myapp` with your app package!!!

adb shell bmgr backupnow com.mycompany.myapp # Create backup

adb shell bmgr restore 1 com.mycompany.myapp
                    # ^^^ use a fake id `1` to show list of available sets
# No matching restore set token.  Available sets:
#  3a945fc11efadf47 : Google Pixel 7 Pro
# done

adb shell bmgr restore 3a945fc11efadf47 com.mycompany.myapp # Now use a real id, to restore backup

规则

我为您的方便起见为最受欢迎的本机包制定了一系列准则。

<include domain="database" path="RKStorage"/>
<include domain="database" path="RKStorage-journal"/>

koude8

SharedPreferences.setName("my_name"); // js part

<include domain="sharedpref" path="my_name.xml" /> // android part

koude9

<include domain="file" path="./mmkv" />

koude10 cookies 

<include domain="root" path="./app_webview"/>

<include domain="file" path="./default.realm" />
<include domain="file" path="./default.realm.lock" />
<include domain="file" path="./default.realm.management" />
<include domain="file" path="./default.realm.note" />

koude12

<include domain="root" path="./watermelon.db"/>
<include domain="root" path="./watermelon.db-wal"/>
<include domain="root" path="./watermelon.db-shm"/>

如何创建自己的规则 

adb shell

run-as com.mycompany.myapp # Replace `com.mycompany.myapp` with your app package!!!

find . -type f # will print all files

# 1) For files in directory `./files/*`
#     <include domain="file" path="./mmkv" />
#                                  ^^^^^^ ./files/mmkv

# 2) For `./shared_prefs/*.xml`
#    <include domain="sharedpref" path="my_name.xml" />
#                                       ^^^^^^^^^ ./shared_prefs/my_name.xml
