创建Account服务
public class XXAuthService extends Service { private XXAuthenticator mAuthenticator; @Override public void onCreate() { mAuthenticator = new XXAuthenticator(this); } private XXAuthenticator getAuthenticator() { if (mAuthenticator == null) mAuthenticator = new XXAuthenticator(this); return mAuthenticator; } @Override public IBinder onBind(Intent intent) { return getAuthenticator().getIBinder(); } class XXAuthenticator extends AbstractAccountAuthenticator { private final Context context; private AccountManager accountManager; public XXAuthenticator(Context context) { super(context); this.context = context; accountManager = AccountManager.get(context); } @Override public Bundle addAccount(AccountAuthenticatorResponse response, String accountType, String authTokenType, String[] requiredFeatures, Bundle options) throws NetworkErrorException { // 添加账号 示例代码 final Bundle bundle = new Bundle(); final Intent intent = new Intent(context, AuthActivity.class); intent.putExtra(AccountManager.KEY_ACCOUNT_AUTHENTICATOR_RESPONSE, response); bundle.putParcelable(AccountManager.KEY_INTENT, intent); return bundle; } @Override public Bundle getAuthToken(AccountAuthenticatorResponse response, Account account, String authTokenType, Bundle options) throws NetworkErrorException { // 认证 示例代码 String authToken = accountManager.peekAuthToken(account, getString(R.string.account_token_type)); //if not, might be expired, register again if (TextUtils.isEmpty(authToken)) { final String password = accountManager.getPassword(account); if (password != null) { //get new token authToken = account.name + password; } } //without password, need to sign again final Bundle bundle = new Bundle(); if (!TextUtils.isEmpty(authToken)) { bundle.putString(AccountManager.KEY_ACCOUNT_NAME, account.name); bundle.putString(AccountManager.KEY_ACCOUNT_TYPE, account.type); bundle.putString(AccountManager.KEY_AUTHTOKEN, authToken); return bundle; } //no account data at all, need to do a sign final Intent intent = new Intent(context, AuthActivity.class); intent.putExtra(AccountManager.KEY_ACCOUNT_AUTHENTICATOR_RESPONSE, response); intent.putExtra(AuthActivity.ARG_ACCOUNT_NAME, account.name); bundle.putParcelable(AccountManager.KEY_INTENT, intent); return bundle; } @Override public String getAuthTokenLabel(String authTokenType) { // throw new UnsupportedOperationException(); return null; } @Override public Bundle editProperties(AccountAuthenticatorResponse response, String accountType) { return null; } @Override public Bundle confirmCredentials(AccountAuthenticatorResponse response, Account account, Bundle options) throws NetworkErrorException { 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; } } }
声明Account服务
<service android:name="**.XXAuthService" android:exported="true" android:process=":core"> <intent-filter> <action android:name="android.accounts.AccountAuthenticator"/> </intent-filter> <meta-data android:name="android.accounts.AccountAuthenticator" android:resource="@xml/authenticator"/> </service>
其中authenticator为:
<?xml version="1.0" encoding="utf-8"?> <account-authenticator xmlns:android="http://schemas.android.com/apk/res/android" android:accountType="@string/account_auth_type" android:icon="@drawable/icon" android:smallIcon="@drawable/icon" android:label="@string/app_name" />
使用Account服务
同SyncAdapter,通过AccountManager使用
。申请Token主要是通过 AccountManager.getAuthToken)系列方法
。添加账号则通过 AccountManager.addAccount)
。查看是否存在账号通过 AccountManager.getAccountsByType)
