android - Custom sync not working with Google Account (com.google) on some Samsung devices -

i implemented sync task same way basicsyncadapter example except google account in answer:

https://stackoverflow.com/a/2972918/2072569

it works on allmost devices except samsung sm-p600 (galaxy note 2014) android 4.4.2 , other samsung tablets.

my contentprovider in manifest file has label. cause of bug according this post @ android version of samsung tablets.

has samsung blocked adding sync tasks google account reason?

the sync added this:

removeallsynctasks(); contentresolver.setissyncable(maccount, content_authority, 1); contentresolver.setsyncautomatically(maccount, content_authority, true); contentresolver.addperiodicsync(maccount, content_authority, bundle.empty, sync_frequency); 

manifest part:

        <service             android:name=".data.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/syncadapter" />         </service>           <provider             android:name=".data.provider.levenscontentprovider"             android:authorities="@string/authority"             android:label="@string/app_name_sync"             android:exported="false"             android:syncable="true" /> 

syncadapter xml:

<?xml version="1.0" encoding="utf-8"?> <sync-adapter     xmlns:android="http://schemas.android.com/apk/res/android"     android:contentauthority="@string/authority"     android:accounttype="com.google"     android:uservisible="true"     android:supportsuploading="true"     android:allowparallelsyncs="false"     android:isalwayssyncable="true"/>  

when manually start sync. syncservice not starting @ samsung tablets (it works on other devices).

it turns out had nothing samsung / os version...

the constructor of synchelper was:

 public synchelper(context context, string accountname) {         account account = null;         account[] accounts = accountmanager.get(context).getaccounts();         (account acc : accounts) {             if(acc.name.equals(accountname)){                 account = acc;             }         }         if(account == null){             throw new invalidparameterexception("account not found");         }         init(context, account);     } 

this not check type of account. there account of type com.evernote in list , used sync , ofcourse won't work.

added solve it:

 public synchelper(context context, string accountname) {         account account = null;         account[] accounts = accountmanager.get(context).getaccounts();         (account acc : accounts) {             if(acc.name.equals(accountname) && acc.type.equals(account_type)){                 account = acc;             }         }         if(account == null){             throw new invalidparameterexception("account not found");         }         init(context, account);     } 

now can start bumping head against wall... ;-)
