我正在开发一个应用程序，该应用程序允许您在应用程序中创建联系人，并且可以使用联系人提供程序将其导出到本机联系人数据库，也可以使用我的应用程序将联系人同步到服务器。
我正在使用SyncAdapter来实现双向联系人同步。我已经使用AccountName用AccountType和AuthenticatorService创建了一个帐户
public class AuthenticationService extends Service {
private Authenticator mAuthenticator;
public AuthenticationService() {
mAuthenticator = new Authenticator(this);
}
public class Authenticator extends AbstractAccountAuthenticator {
// Simple constructor
public Authenticator(Context context) {
super(context);
}
@Override
public Bundle editProperties(AccountAuthenticatorResponse response, String accountType) {
return null;
}
@Override
public Bundle addAccount(AccountAuthenticatorResponse response, String accountType, String authTokenType, String[] requiredFeatures, Bundle options) throws NetworkErrorException {
return null;
}
@Override
public Bundle confirmCredentials(AccountAuthenticatorResponse response, Account account, Bundle options) throws NetworkErrorException {
return null;
}
@Override
public Bundle getAuthToken(AccountAuthenticatorResponse response, Account account, String authTokenType, Bundle options) throws NetworkErrorException {
return null;
}
@Override
public String getAuthTokenLabel(String authTokenType) {
return null;
}
@Override
public Bundle updateCredentials(AccountAuthenticatorResponse response, Account account, String authTokenType, Bundle options) throws NetworkErrorException {
return null;
}
@Override
public Bundle hasFeatures(AccountAuthenticatorResponse response, Account account, String[] features) throws NetworkErrorException {
return null;
}
}
@Nullable
@Override
public IBinder onBind(Intent intent) {
return mAuthenticator.getIBinder();
}
}
下面是我的authenticator.xml
<?xml version="1.0" encoding="utf-8"?>
<account-authenticator
xmlns:android="http://schemas.android.com/apk/res/android"
android:accountType="com.contacts.example"
android:icon="@drawable/ico_reply_all_svg"
android:smallIcon="@drawable/ic_launcher_background"
android:label="@string/app_name"/>
下面是我的ContactSyncAdapterService
public class ContactSyncService extends Service {
private static SyncAdapterImpl sSyncAdapter = null;
private static final Object sSyncAdapterLock = new Object();
private static Context mContext;
private static ContentResolver cr;
private static class SyncAdapterImpl extends AbstractThreadedSyncAdapter {
public SyncAdapterImpl(Context context,ContentResolver c) {
super(context, true);
mContext = context;
cr = c;
}
@Override
public void onPerformSync(Account account, Bundle extras, String authority, ContentProviderClient provider, SyncResult syncResult) {
Log.d("TEST", "onPerformSync Called");
// run sync with server
}
}
@Override
public void onCreate() {
super.onCreate();
synchronized (sSyncAdapterLock) {
if(sSyncAdapter == null) {
sSyncAdapter = new SyncAdapterImpl(getApplicationContext(), getContentResolver());
}
}
}
@Nullable
@Override
public IBinder onBind(Intent intent) {
return sSyncAdapter.getSyncAdapterBinder();
}
}
和syncadapter.xml
<?xml version="1.0" encoding="utf-8"?>
<sync-adapter
xmlns:android="http://schemas.android.com/apk/res/android"
android:contentAuthority="com.android.contacts"
android:accountType="com.contacts.example"
android:userVisible="true"
android:supportsUploading="true"
android:allowParallelSyncs="false"
android:isAlwaysSyncable="true"/>
以下是我如何使用accountName和accountType将联系人导出到本机联系人数据库的方式
public void addContact() {
ArrayList<ContentProviderOperation> ops =
new ArrayList<ContentProviderOperation>();
int rawContactInsertIndex = ops.size();
ops.add(ContentProviderOperation.newInsert(RawContacts.CONTENT_URI)
.withValue(RawContacts.ACCOUNT_TYPE, "com.contacts.example")
.withValue(RawContacts.ACCOUNT_NAME, "dummyaccount1")
.withValue(RawContacts.RAW_CONTACT_IS_READ_ONLY, "0")
.build());
ops.add(ContentProviderOperation.newInsert(Data.CONTENT_URI)
.withValueBackReference(Data.RAW_CONTACT_ID, rawContactInsertIndex)
.withValue(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE)
.withValue(StructuredName.DISPLAY_NAME, "DoomsDay2")
.withValue(Data.IS_READ_ONLY, 0")
.build());
try {
getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
} catch (Exception e) {
e.printStackTrace();
}
}
帐户创建代码如下：
public static Account CreateSyncAccount(Context context) {
public static final String ACCOUNT_TYPE = "com.contacts.example";
// The account name
public static final String ACCOUNT_NAME = "dummyaccount1";
// Create the account type and default account
Account newAccount = new Account(
ACCOUNT_NAME, ACCOUNT_TYPE);
// Get an instance of the Android account manager
AccountManager accountManager =
(AccountManager) context.getSystemService(
ACCOUNT_SERVICE);
/*
* Add the account and account type, no password or user data
* If successful, return the Account object, otherwise report an error.
*/
if (accountManager.addAccountExplicitly(newAccount, null, null)) {
/*
* If you don't set android:syncable="true" in
* in your <provider> element in the manifest,
* then call context.setIsSyncable(account, AUTHORITY, 1)
* here.
*/
} else {
/*
* The account exists or some other error occurred. Log this, report it,
* or handle it internally.
*/
}
return newAccount;
}
下面是面对的问题：
请帮助我解决这个问题！！预先感谢。
