Contacts Provider Not Appears In "google Contacts Application"

I wrote a Contacts provider. It is quite configurable via 'Settings/Accounts', it correctly sync contacts from remote server and these contacts are visible in the 'Google contacts'

Solution 1:

I assume you've created an xml file for you SyncProvider, that xml file has a field userVisible, make sure it's true:

<?xml version="1.0" encoding="utf-8"?><sync-adapterxmlns:android="http://schemas.android.com/apk/res/android"android:contentAuthority="com.example.my_sync_provider"android:accountType="com.example.my_type"android:userVisible="true"android:supportsUploading="true"android:allowParallelSyncs="true"android:isAlwaysSyncable="true" />

read more here: https://developer.android.com/training/sync-adapters/creating-sync-adapter.html and also this is a must read: http://www.c99.org/2010/01/23/writing-an-android-sync-provider-part-1/ (part 2 as well)

Solution 2:

thanks. I have this attribute. I discovered that the problem was generated by a doubled calendar-related xml which refer an undefined account type
