    <p>I keep getting lots of notifications from this question, so I thought I'll share this info. This is how you add SyncAdapter without Account. You can put this in <code>onCreate</code> of <code>MyApplication extends Application</code> class. This assumes you already have a <code>SyncAdapter</code> and <code>ContentProvider</code> implemented. You can do that by following the tutorials listed in the question.</p> <pre><code>final String ACCOUNT_NAME = "MyApp"; final String ACCOUNT_TYPE = "com.myapp.account"; final String PROVIDER = "com.myapp.provider"; Account appAccount = new Account(ACCOUNT_NAME,ACCOUNT_TYPE); AccountManager accountManager = AccountManager.get(getApplicationContext()); if (accountManager.addAccountExplicitly(appAccount, null, null)) { ContentResolver.setIsSyncable(appAccount, PROVIDER, 1); ContentResolver.setMasterSyncAutomatically(true); ContentResolver.setSyncAutomatically(appAccount, PROVIDER, true); } </code></pre> <p>res/xml/syncadapter.xml</p> <pre><code>&lt;sync-adapter xmlns:android="http://schemas.android.com/apk/res/android" android:contentAuthority="@string/provider" android:accountType="@string/account_type" android:userVisible="true" android:supportsUploading="true" /&gt; </code></pre> <p>res/xml/authenticator.xml</p> <pre><code>&lt;account-authenticator xmlns:android="http://schemas.android.com/apk/res/android" android:accountType="@string/account_type" android:icon="@drawable/app_icon" android:smallIcon="@drawable/app_icon" android:label="@string/app_label" /&gt; </code></pre>

    1. COcalling `setMasterSyncAutomatically(true)` here is bad practice, in my opinion...

    2. CONot only is it bad practice, but it requires android.permission.WRITE_SYNC_SETTINGS. You shouldn't be overriding your users' choice to disable sync. And especially not the master setting.

    3. COWhere does `authenticator.xml` get used? Don't you need to subclass `AbstractAccountAuthenticator` as well?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
