我正在开发一个 Android 帐户应用程序。现在我可以在 Android 中添加我自己的帐户。但是当我打开联系人应用程序并切换到群组寻呼机时，它会显示“没有群组。要创建群组，您需要一个帐户。 ”。那么如何让android知道我的账号可以加群呢？
下面是我的xml文件：
AndroidManifest.xml：
<!-- The sync service -->
<service
android:name="com.snail.android.sync.SyncService"
android:exported="true"
android:process=":sync">
<intent-filter>
<action android:name="android.content.SyncAdapter"/>
</intent-filter>
<meta-data
android:name="android.content.SyncAdapter"
android:resource="@xml/contacts_sync_adapter"/>
<meta-data
android:name="android.provider.CONTACTS_STRUCTURE"
android:resource="@xml/contacts"/>
</service>
联系人.xml：
<?xml version="1.0" encoding="utf-8"?>
<ContactsAccountType>
<EditSchema>
<!--
Name:
- maxOccurs must be 1
- No types.
- Currently all the supportsXxx attributes must be true, but here's the plan for the
future:
(There's some hardcoded assumptions in the contact editor, which is one reason
for the above restriction)
- "Family name" and "Given name" must be supported.
- All sync adapters must support structured name. "display name only" is not
supported.
-> Supporting this would require relatively large changes to
the contact editor.
- Fields are decided from the attributes:
StructuredName.DISPLAY_NAME if supportsDisplayName == true
StructuredName.PREFIX if supportsPrefix == true
StructuredName.FAMILY_NAME (always)
StructuredName.MIDDLE_NAME if supportsPrefix == true
StructuredName.GIVEN_NAME (always)
StructuredName.SUFFIX if supportsSuffix == true
StructuredName.PHONETIC_FAMILY_NAME if supportsPhoneticFamilyName == true
StructuredName.PHONETIC_MIDDLE_NAME if supportsPhoneticMiddleName == true
StructuredName.PHONETIC_GIVEN_NAME if supportsPhoneticGivenName == true
- DataKind.PSEUDO_MIME_TYPE_DISPLAY_NAME is always added.
- DataKind.PSEUDO_MIME_TYPE_PHONETIC_NAME is added
if any of supportsPhoneticXxx == true
