Question

我在我的应用程序中使用accountmanager。我首先检查一个帐户，看它是否存在。如果没有，则明确添加。该代码在addaccountexplicitly()

中崩溃

Account[] accounts = AccountManager.get(this).getAccountsByType(getString(R.string.authtype));
        if(accounts.length==1)
        {
            Toast.makeText(this,accounts[0].name,Toast.LENGTH_SHORT).show();
            Intent i = new Intent(Splash.this, MapsActivity.class);
            startActivity(i);
            finish();
        }
        else
        {
            boolean accountCreated = mAccountManager.addAccountExplicitly(new Account("sasa",getString(R.string.authtype)), "", null);

            Intent i = new Intent(Splash.this, MainActivity.class);
            startActivity(i);
            finish();
        }

要使设备处理自定义帐户类型，必须为该帐户类型注册验证器。

获得验证者后，将其声明为清单中的服务：

        <service
            android:name=".MyAuthenticationService"
            android:exported="false" >
            <intent-filter>
                <action android:name="android.accounts.AccountAuthenticator" />
            </intent-filter>

            <meta-data
                android:name="android.accounts.AccountAuthenticator"
                android:resource="@xml/authenticator" />
        </service>

然后/res/xml/authenticator.xml会告诉系统您的帐户类型：

<account-authenticator xmlns:android="http://schemas.android.com/apk/res/android"
    android:accountType="@string/authtype"
    android:label="@string/app_name"
    android:icon="@drawable/ic_launcher"
    android:smallIcon="@drawable/ic_launcher" />

您还需要获得许可

    <uses-permission android:name="android.permission.AUTHENTICATE_ACCOUNTS" />
