Android SecurityException:uid xxxxx无法显式添加帐户 [英] Android SecurityException: uid xxxxx cannot explicitly add accounts

问题描述

我收到错误消息

java.lang.SecurityException: uid 10178 cannot explicitly add accounts of type: net.roughdesign.swms

即使是我可以创建的最基本的示例.它包括:

even with the most basic example I could create. It consists of:

strings.xml中的帐户类型

<string name="accounts__account_type">net.roughdesign.swms</string>

authenticator.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <account-authenticator xmlns:android="http://schemas.android.com/apk/res/android"
            android:accountType="@string/accounts__account_type"
            android:icon="@drawable/ic_add_black_24dp"
            android:smallIcon="@drawable/ic_add_black_24dp"
            android:label="@string/global__authenticator_account_label"
            />

</resources>

SwmsAccountAuthenticator.kt

class SwmsAccountAuthenticator(val context: Context) : AbstractAccountAuthenticator(context) {

    override fun addAccount(
        response: AccountAuthenticatorResponse, accountType: String, authTokenType: String?,
        requiredFeatures: Array<out String>?, options: Bundle?
    ): Bundle? {
        return null
    }


    override fun confirmCredentials(response: AccountAuthenticatorResponse, account: Account, options: Bundle?)
            : Bundle? {
        return null
    }


    override fun editProperties(response: AccountAuthenticatorResponse?, accountType: String?): Bundle? {
        return null
    }


    override fun getAuthToken(
        response: AccountAuthenticatorResponse, accountInput: Account, authTokenType: String, options: Bundle?
    ): Bundle? {

        return null
    }


    override fun getAuthTokenLabel(authTokenType: String): String? {
        return null
    }


    override fun hasFeatures(response: AccountAuthenticatorResponse, account: Account, features: Array<out String>)
            : Bundle? {
        return null
    }


    override fun updateCredentials(
        response: AccountAuthenticatorResponse, account: Account, authTokenType: String?, options: Bundle?
    ): Bundle? {
        return null
    }
}

SwmsAuthenticatorService.kt

class SwmsAuthenticatorService : Service() {
    override fun onBind(intent: Intent?): IBinder? {
        val authenticator = SwmsAccountAuthenticator(this)
        return authenticator.iBinder
    }
}

最后，在AndroidManifest.xml

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

<application ... >

    <service
            android:name=".users.SwmsAuthenticatorService"
            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>

   ...
</application>

尝试使用它

我尝试以此创建一个帐户:

Trying to use it

I try to create an account with this:

val username = "myUserName"
val password = "myPassword"

val accountManager = AccountManager.get(this)
val accountType = getString(R.string.accounts__account_type)
val account = Account(username, accountType)

val accountAdded = accountManager.addAccountExplicitly(account, password, null)

然后对于最后一行(accountManager.addAccountExplicitly)，我收到上述错误:

then for the last line (accountManager.addAccountExplicitly), I receive the aforementioned error:

   java.lang.SecurityException: uid 10178 cannot explicitly add accounts of type: net.roughdesign.swms
        at android.os.Parcel.readException(Parcel.java:2013)
        at android.os.Parcel.readException(Parcel.java:1959)
        at android.accounts.IAccountManager$Stub$Proxy.addAccountExplicitly(IAccountManager.java:1205)
        at android.accounts.AccountManager.addAccountExplicitly(AccountManager.java:878)
        at net.roughdesign.swms.swmsandroid.users.AuthenticateActivity.submit(AuthenticateActivity.kt:68)
...

我完全不知道这里仍然是什么问题.据我所知，通过在清单中添加<service>部分，帐户类型(net.roughdesign.swms)已在我的应用程序中注册"，但我认为android不接受这是我的".

I have absolutely no idea what could still be the issue here. As far as I'm aware, the account type (net.roughdesign.swms) is "registered" with my app by adding the <service> part in the manifest, but I think android doesn't accept that "it's mine".

这里仍然是什么问题?

推荐答案

常规解决方案-如何调试

在android studio的logcat视图中，默认过滤器设置为仅显示选定的应用程序".我 did 收到有关我的帐户服务无法注册的日志，包括原因.但是，使用默认的过滤器设置，它们不会显示！

General solution - how to debug this

In android studio's logcat view, the default filter setting is "Show only selected application". I did receive logs about my account service being unable to register, including the reason why. However, with the default filter setting, they were not shown!

因此，为了了解此处实际发生的情况，请将过滤器设置切换为无过滤器".这将使有问题的错误消息出现.

So, in order to get an idea what is actually happening here, switch the filter setting to "No Filters". That will make the error message in question appear.

但是，它会显示 all 条日志消息，因此您将获得一吨日志消息.我必须滚动很多才能看到该错误消息.我的建议是，在您获得所需的内容后，将过滤器重新显示为仅显示选定的应用程序".

However, it shows all log messages, so you'll get you a ton of them. I had to scroll quite a bit to see that error message. My advice would be to turn the filter back to "Show only selected application" after you got what you need.

问题出在authenticator.xml上.该文件不应包含<resources>元素. <account-authenticator>必须是顶层元素；完整的文件应如下所示:

The problem was with authenticator.xml. This file should not have a <resources> element. <account-authenticator> needs to be a top level element; the complete file needs to look like this:

<?xml version="1.0" encoding="utf-8"?>
<account-authenticator xmlns:android="http://schemas.android.com/apk/res/android"
        android:accountType="@string/accounts__account_type"
        android:icon="@drawable/ic_add_black_24dp"
        android:label="@string/global__authenticator_account_label"
        android:smallIcon="@drawable/ic_add_black_24dp" />
