java - 为什么 Accountmanager.get(context).getAccounts() 返回 securityException？

Question

据我了解，Accountmanager.get(context).getAccounts 无法返回安全异常，因为它不需要权限。来自文档:

Clients of this method that have not been granted the GET_ACCOUNTS permission, will only see those accounts managed by AbstractAccountAuthenticators whose signature matches the client.

https://developer.android.com/reference/android/accounts/AccountManager.html#getAccounts()

因此，看起来好像您没有 GET_ACCOUNTS 那么没关系，但我的应用程序在调用该方法时崩溃，但出现以下异常:

caller uid # lacks any of android.permission.GET_ACCOUNTS

为什么会发生这种情况？

Account[] accounts = AccountManager.get(parentActivity).getAccounts();

Answer 1

您的应用在 list 中缺少匹配的权限。 添加

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

到你的AndroidManifest.xml

编辑:对于 Android 6.0，在运行时请求:http://developer.android.com/training/permissions/requesting.html

GET ACCOUNTS: Allows access to the list of accounts in the Accounts Service. Protection level: dangerous
