Android是否有多个同步适配器项，例如Google帐户? [英] Android multiple sync adapter items like Google Account?

问题描述

我目前已设置Android应用程序以使用Android的AccountManager功能，并使用SyncAdapter和经过身份验证的帐户来自动执行同步.

I currently have my Android app set up to use the AccountManager feature of Android, using a SyncAdapter and an authenticated account to performs syncs automatically.

我只有一个运行中的同步适配器，它可以同步所有内容，但是我想将其分开，以便以不同的间隔对不同的内容执行同步.

I only have 1 sync adapter running which syncs all content, but I would like to separate this out to performs syncs for different content at different intervals.

我如何像Google一样拥有多个同步项目?

How can I have multiple sync items like Google does?

推荐答案

您只需要使用相同的帐户类型定义多个同步适配器即可.

You just have to define several sync adapters, using the same account type.

清单包含:

<service android:exported="true" android:name="com.example.FooSyncAdapterService">
  <intent-filter>
    <action android:name="android.content.SyncAdapter" />
  </intent-filter>
  <meta-data android:name="android.content.SyncAdapter" android:resource="@xml/syncadapter_foo" />
</service>
<service android:exported="true" android:name="com.example.BarSyncAdapterService">
  <intent-filter>
    <action android:name="android.content.SyncAdapter" />
  </intent-filter>
  <meta-data android:name="android.content.SyncAdapter" android:resource="@xml/syncadapter_bar" />
</service>

syncdataper_foo是

<sync-adapter xmlns:android="http://schemas.android.com/apk/res/android"
    android:contentAuthority="foo"
    android:accountType="com.example"
    android:allowParallelSyncs="true" />

syncdataper_bar是

<sync-adapter xmlns:android="http://schemas.android.com/apk/res/android"
    android:contentAuthority="bar"
    android:accountType="com.example"
    android:allowParallelSyncs="true" />

请注意，在帐户类型为"com.google"的情况下，同步适配器甚至是由其他应用程序提供的(驱动器，文档，表格，Gmail，日历等).

Note that in the case of the account type "com.google", the sync adapters are even provided by different applications (Drive, Docs, Sheets, Gmail, Calendar, etc.).
