I am implementing a syncadapter for an android app and would like to make the settings for the account available under the "Accounts & sync" menu. I have seen this done in the DropBox app(as shown below), but I have not been able to find documentation on how to do this. I have the accounted added, just want to add a link to the account settings in this menu.
In your Android Manifest, you should have a section like this to define your account authenticator:
<service android:name="AccountAuthenticatorService"
android:exported="true" android:process=":auth">
<intent-filter>
<action android:name="android.accounts.AccountAuthenticator" />
</intent-filter>
<meta-data android:name="android.accounts.AccountAuthenticator"
android:resource="@xml/authenticator" />
</service>
The meta-data tag above should point to an XML file that defines your account, like this:
<account-authenticator xmlns:android="http://schemas.android.com/apk/res/android"
android:accountType="fm.last.android.account"
android:icon="@drawable/icon"
android:smallIcon="@drawable/icon"
android:label="@string/app_name"
android:accountPreferences="@xml/account_preferences"/>
The android:accountPreferences attribute above points to an XML file that defines your preferences screen, like so:
<PreferenceScreen
xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory
android:title="General Settings" />
<PreferenceScreen
android:key="account_settings"
android:title="Account Settings"
android:summary="Sync frequency, notifications, etc.">
<intent
android:action="fm.last.android.activity.Preferences.ACCOUNT_SETUP"
android:targetPackage="fm.last.android"
android:targetClass="fm.last.android.activity.Preferences" />
</PreferenceScreen>
</PreferenceScreen>
The above PreferenceScreen will launch an intent to display a settings screen, but you can also define the settings directly in the XML file.
