我想在android上添加AccountManager.addAccount()的自定义帐户.我正在关注this tutorial.当我尝试使用AccountManagerCallback的run方法获取结果时,我收到带有消息的AuthenticatorException：androID.accounts.AuthenticatorException：bind failure.

经过一些研究后,我发现了两个可能的解决方案,但我已经在应用程序标签内部declared authenticator和checked my account type.我还将清单权限与教程中的权限进行了比较.我正在使用androID studio 1.4,我在几个仿真器和物理设备上尝试过它.

这是我的AndroIDManifest.xml,还有authenticator.xml和account_preferences.xml：

<?xml version="1.0" enCoding="utf-8"?><manifest xmlns:androID="http://schemas.androID.com/apk/res/androID"    package="com.test.myproject" >    <uses-permission androID:name="androID.permission.INTERNET" />    <uses-permission androID:name="androID.permission.USE_CREDENTIALS" />    <uses-permission androID:name="androID.permission.GET_ACCOUNTS" />    <uses-permission androID:name="androID.permission.READ_PROfile" />    <uses-permission androID:name="androID.permission.READ_CONTACTS" />    <uses-permission androID:name="androID.permission.AUTHENTICATE_ACCOUNTS"/>    <uses-permission androID:name="androID.permission.MANAGE_ACCOUNTS"/>    <application        androID:allowBackup="true"        androID:icon="@mipmap/test_logo"        androID:label="@string/app_name"        androID:theme="@style/Apptheme" >        <activity            androID:name=".vIEw.MainActivity"            androID:label="@string/app_name" >            <intent-filter>                <action androID:name="androID.intent.action.MAIN" />                <category androID:name="androID.intent.category.LAUNCHER" />            </intent-filter>        </activity>        <activity            androID:name=".vIEw.LoginActivity"            androID:label="@string/app_name">        </activity>        <service            androID:name="com.test.myproject.model.utility.MyAuthenticatorService">            <intent-filter>                <action androID:name="androID.accounts.AccountAuthenticator"/>            </intent-filter>            <Meta-data                androID:name="androID.accounts.AccountAuthenticator"                androID:resource="@xml/authenticator" />        </service>        <Meta-data            androID:name="com.Google.androID.gms.version"            androID:value="@integer/Google_play_services_version" />    </application></manifest>

我也试过命名服务.model.utility.MyAuthenticatorService没有任何效果.

authenticator.xml：

<?xml version="1.0" enCoding="utf-8"?><PreferenceScreen xmlns:androID="http://schemas.androID.com/apk/res/androID">    <account-authenticator xmlns:androID="http://schemas.androID.com/apk/res/androID"        androID:accountType="com.test.myproject"        androID:icon="@drawable/test_logo"        androID:smallicon="@drawable/test_logo"        androID:label="@string/not_implemented"        androID:accountPreferences="@xml/account_preferences"        /></PreferenceScreen>

account_preferences.xml：

<?xml version="1.0" enCoding="utf-8"?><PreferenceScreen xmlns:androID="http://schemas.androID.com/apk/res/androID">    <Preferencecategory androID:title="@string/not_implemented" />    <CheckBoxPreference androID:title="Use deBUG server"        androID:key="isDeBUG"        androID:summary="Connecting to a deBUG server instead of prod server"/>    <SwitchPreference androID:title="DeBUG Logs" androID:key="logsverbose" androID:summary="Show deBUG logs on LogCat"/></PreferenceScreen>

这是MyAuthenticatorService：

public class MyAuthenticatorService extends Service {    @Nullable    @OverrIDe    public IBinder onBind(Intent intent) {        MyAuthenticator myAuthenticator = new MyAuthenticator(this);        return myAuthenticator.getIBinder();    }}

这是MyAuthenticator：

public class MyAuthenticator extends AbstractAccountAuthenticator {    private Context context;    public MyAuthenticator(Context context) {        super(context);        this.context = context;    }    @OverrIDe    public Bundle addAccount(AccountAuthenticatorResponse response, String accountType, String authTokenType, String[] requiredFeatures, Bundle options) throws NetworkErrorException {        final Intent intent = new Intent(context, LoginActivity.class);        intent.putExtra(LoginActivity.ARG_ACCOUNT_TYPE, accountType);        intent.putExtra(LoginActivity.ARG_AUTH_TYPE, authTokenType);        intent.putExtra(LoginActivity.ARG_IS_ADDING_NEW_ACCOUNT, true);        intent.putExtra(AccountManager.KEY_ACCOUNT_AUTHENTICATOR_RESPONSE, response);        final Bundle bundle = new Bundle();        bundle.putParcelable(AccountManager.KEY_INTENT, intent);        return bundle;    }   //other overrIDe methods (they all return null for Now)}

这是MainActivity：

public class MainActivity extends AppCompatActivity {    private Toolbar toolbar;    private NavigationVIEw navigationVIEw;    private DrawerLayout drawerLayout;    private SharedPreferences sharedPreferences;    private AccountManager accountManager;    private static final String ACCOUNT_TYPE = "com.test.myproject";    @OverrIDe    protected voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentVIEw(R.layout.activity_drawer);        this.accountManager = AccountManager.get(this);        signIn(ACCOUNT_TYPE, "access_token");        //other stuff    }    private voID signIn(String accountType, String authTokenType) {        final AccountManagerFuture<Bundle> future = accountManager.addAccount(ACCOUNT_TYPE, authTokenType, null, null, this, new AccountManagerCallback<Bundle>() {            @OverrIDe            public voID run(AccountManagerFuture<Bundle> future) {                try {                    Bundle bnd = future.getResult();                    showMessage("Account was created");                    Log.d("udinic", "AddNewAccount Bundle is " + bnd);                } catch (Exception e) {                    e.printstacktrace();                    showMessage(e.getMessage());                }            }        }, null);    }}

当debBUGing时,在Bundle bnd = future.getResult();上抛出错误,并且future具有状态3和结果androID.accounts.AuthenticatorException：绑定失败.艰难的执行永远不会到达LoginActivity,或者至少不会触发断点,这里是：

public class LoginActivity extends AccountAuthenticatorActivity {    public final static String ARG_ACCOUNT_TYPE = "ACCOUNT_TYPE";    public final static String ARG_ACCOUNT_name = "AUTH_TYPE";    public final static String ARG_AUTH_TYPE = "ACCOUNT_name";    public final static String ParaM_USER_PASS = "USER_PASS";    private AccountManager accountManager;    @OverrIDe    protected voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentVIEw(R.layout.activity_login);        this.accountManager = AccountManager.get(getBaseContext());    }    public voID login(VIEw vIEw) {        EditText usernameEditText = (EditText)findVIEwByID(R.ID.textLoginUsername);        EditText passwordEditText = (EditText)findVIEwByID(R.ID.textLoginPassword);        String ownerUsername = usernameEditText.getText().toString();        String ownerPassword = passwordEditText.getText().toString();        String clIEntID = "test";        String clIEntSecret = "test";        AccountManager manager = AccountManager.get(this);        TokenRequestTask tokenRequestTask = new TokenRequestTask();        tokenRequestTask.execute(ownerUsername, ownerPassword, clIEntID, clIEntSecret);    }    private class TokenRequestTask extends AsyncTask<String, VoID, Intent> {        @OverrIDe        protected Intent doInBackground(String... params) {            final String accountType = getIntent().getStringExtra(ARG_ACCOUNT_TYPE);            String ownerUsername = params[0];            String ownerSecret = params[1];            String clIEntID = params[2];            String clIEntSecret = params[3];            String authToken = signIn(clIEntID, clIEntSecret, ownerUsername, ownerSecret, "password");            Bundle resultData = new Bundle();            resultData.putString(AccountManager.KEY_ACCOUNT_name, ownerUsername);            resultData.putString(AccountManager.KEY_ACCOUNT_TYPE, accountType);            resultData.putString(AccountManager.KEY_AUTHTOKEN, authToken);            resultData.putString(ParaM_USER_PASS, ownerSecret);            final Intent resultIntent = new Intent();            resultIntent.putExtras(resultData);            return resultIntent;        }    }    private String signIn(String clIEntID, String clIEntSecret, String ownerUsername, String ownerSecret, String grantType) {        MyAPI20ServiceImpl service = (MyAPI20ServiceImpl)new ServiceBuilder().provIDer(MyAPI20.class)                .APIKey(clIEntID)                .APISecret(clIEntSecret)                .signatureType(SignatureType.queryString)                .build();        Token token = service.getAccesstoken(ownerUsername, ownerSecret, grantType);        return token.getToken();    }}

有人可以帮我解决这个问题吗？

解决方法:

好的,所以,它真的是一个复制粘贴错误,它让我发疯.在authenticator.xml中：

<?xml version="1.0" enCoding="utf-8"?><PreferenceScreen xmlns:androID="http://schemas.androID.com/apk/res/androID">    <account-authenticator xmlns:androID="http://schemas.androID.com/apk/res/androID"        androID:accountType="com.test.myproject"        androID:icon="@drawable/test_logo"        androID:smallicon="@drawable/test_logo"        androID:label="@string/not_implemented"        androID:accountPreferences="@xml/account_preferences"        /></PreferenceScreen>

&LT / PreferenceScreen&GT不应该在这里.

如果您收到此错误,请检查您的xml文件.
