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();
    }
}

这是完整的堆栈跟踪：

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.
