我正在尝试AccountManager.addAccount()在 android 上添加自定义帐户。我正在关注本教程。当我试图用AccountManagerCallback'srun方法得到结果时，我得到AuthenticatorException了 message: android.accounts.AuthenticatorException: bind failure。
经过一番研究，我发现了两种可能的解决方案，但我已经在标签内声明了验证器，并检查了我的帐户类型。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，并在几个模拟器和物理设备上进行了尝试。application
这是我的AndroidManifest.xml，也是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" >

</service>
<meta-data

</manifest>
我也尝试过.model.utility.MyAuthenticatorService没有效果的命名服务。
身份验证器.xml：
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">

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" />

<SwitchPreference android:title="Debug Logs" android:key="logsVerbose" android:summary="Show debug logs on LogCat"/>
</PreferenceScreen>
这里是MyAuthenticatorService：
public class MyAuthenticatorService extends Service {
@Nullable
@Override
public IBinder onBind(Intent intent) {
MyAuthenticator myAuthenticator = new MyAuthenticator(this);
return myAuthenticator.getIBinder();
}
}
这里是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);
}
}
调试时，会抛出错误Bundle bnd = future.getResult();，future 有状态 3 和结果android.accounts.AuthenticatorException: bind failure。艰难的执行永远不会到达 LoginActivity，或者至少没有触发断点，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？
