Hello,
I am trying to create Authenticator, but when I try to create new account I get java.lang.ClassNotFoundException error
I tried to lookup for solutions, but I didn´t find anything that helped

my Manifest:

<?xml version="1.0" encoding="UTF-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="1" android:versionName="1.0" package="Apptest.Apptest"> <uses-sdk android:minSdkVersion="12" /> <uses-permission android:name="android.permission.GET_ACCOUNTS" /> <uses-permission android:name="android.permission.USE_CREDENTIALS" /> <uses-permission android:name="android.permission.MANAGE_ACCOUNTS" /> <uses-permission android:name="android.permission.AUTHENTICATE_ACCOUNTS" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.WRITE_SETTINGS" /> <uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" /> <uses-permission android:name="android.permission.READ_CONTACTS" /> <uses-permission android:name="android.permission.WRITE_CONTACTS" /> <uses-permission android:name="android.permission.READ_SYNC_STATS" /> <uses-permission android:name="android.permission.READ_SYNC_SETTINGS" /> <uses-permission android:name="android.permission.WRITE_SYNC_SETTINGS" /> <uses-permission android:name="android.permission.ACCOUNT_MANAGER" /> <application android:label="@string/app_name"> <service android:name=".AuthenticatorService" android:exported="false"> <intent-filter> <action android:name="android.accounts.AccountAuthenticator" /> </intent-filter> <meta-data android:name="android.accounts.AccountAuthenticator" android:resource="@xml/authenticator" /> </service> <activity android:name=".AuthenticatorActivity" android:label="@string/ui_activity_title" android:theme="@android:style/Theme.Dialog" android:excludeFromRecents="true"></activity> <activity android:name=".MainActivity" android:label="@string/ui_activity_title" android:theme="@android:style/Theme.Dialog" android:excludeFromRecents="true"></activity> </application> </manifest>

and my class:

`namespace Apptest
{
class AuthenticatorService : Service
{
private static string TAG = "AuthenticatorService";
private Authenticator mAuthenticator;

    public override void OnCreate() {
        mAuthenticator = new Authenticator(this);
    }


    public override void OnDestroy() {
    }
    public override IBinder OnBind(Intent intent) {
        return mAuthenticator.IBinder;
    }
}

}`

Thanks in advance

I'm not sure if putting your service in the app manifest is the best way to go. You can simply put an attribute in your service class.

[Service (Exported=false)]
public class AuthenticatorService {
....
