  java.lang.SecurityException异常：权限拒绝：阅读com.android.providers.contacts.HtcContactsProvider2
URI内容：从PID = 14938，UID //com.android.contacts/data/2158 = 10125要求android.permission.READ_CONTACTS
 

我已阅读，当用户通过手的接触appliaction被授予所需的权限。但是在某些手机上不起作用（HTC EVO 3D）。

这是为什么happending？有一种解决方法，例如在运行时，要求此权限的能力吗？

解决方案

  

HTC ONE并不需要：＆LT;使用许可权的android：NAME =android.permission.READ_CONTACTS/＆GT; 上HTC EVO 3D然而，随着code抛出一个异常

如果在乌里你正在从 ACTION_PICK 即将或 ACTION_GET_CONTENT ，你是否拥有该联系人的临时读取权限将通过接触采摘的应用程序有所不同。

  

我已阅读，当用户通过手的接触appliaction被授予所需的权限。但是在某些手机上不起作用（HTC EVO 3D）。

有没有要求所有接触采摘的应用程序授予您的联系人临时读取访问。其实，我不清楚，如果第三方联系人管理器必须授予您的联系人临时读访问的能力。

  

是否有这样一种解决方法是要求在运行此权限的能力吗？

您不能要求在运行时的权限。

您的选择是：

1. 在清单总是询问 READ_CONTACTS 。这将确保你可以做你想做的，在请求另一个许可，一个未来的用户可能不喜欢的费用。




2. 办理的 SecurityException异常，只是离不开你试图查询的数据（），如果该数据不是必须的。




3. 编写与可以作为一个插件为您的应用程序，安全地取回代表你的主要应用程序的联系人数据的 READ_CONTACTS 权限的单独的应用程序。然后，您可以将用户路由谁获得 SecurityException异常来安装您的联系人插件。这是棘手，而不会引入安全漏洞来写，所以我会鼓励你使用任何其他选项。

I have a HTC ONE M7 (GPE 4.2.2) and HTC EVO 3D (4.0.3) HTC Sense 3.6

HTC ONE does not need:

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

on HTC EVO 3D however, following code throws an exception:

 public static String getPhoneNumberFromIntent(Context context, Intent data) throws SecurityException {
    String contactNumber = null;
    final Uri contactUri = data.getData();
    if (contactUri != null) {
        Cursor c = null;
        try {
            // Read contact number from contacts provider
            String[] projection = new String[] {ContactsContract.CommonDataKinds.Phone.NUMBER};
            c = context.getContentResolver().query(contactUri, projection, null, null, null);
            if (c != null && c.moveToFirst()) {
                int maxNumberLength = context.getResources().getInteger(R.integer.max_phone_number_cze);
                contactNumber = cutOnlyLastPhoneNumberDigits(c.getString(0), maxNumberLength);
            }
        } finally {
            if (c != null) {
                c.close();
            }
        }
    }
    return contactNumber;

java.lang.SecurityException: Permission Denial: reading com.android.providers.contacts.HtcContactsProvider2
uri content://com.android.contacts/data/2158 from pid=14938, uid=10125 requires android.permission.READ_CONTACTS

I have read that appliaction is granted required permissions when user selects contact by hand. However on some phones this does not work (HTC EVO 3D).

Why is this happending? Is there a workaround such is ability to ask for this permission at runtime ?

解决方案

HTC ONE does not need: <uses-permission android:name="android.permission.READ_CONTACTS" /> on HTC EVO 3D however, following code throws an exception

If the Uri you are getting is coming from ACTION_PICK or ACTION_GET_CONTENT, whether or not you have temporary read permissions for that contact will vary by contact-picking app.

I have read that appliaction is granted required permissions when user selects contact by hand. However on some phones this does not work (HTC EVO 3D).

There is no requirement that all contact-picking apps grant you temporary read access to the contact. In fact, I am unclear if third-party contact managers would have the ability to grant you temporary read access to the contact.

Is there a workaround such is ability to ask for this permission at runtime ?

You cannot ask for a permission at runtime.

Your choices are:

1. Always ask for READ_CONTACTS in the manifest. This ensures you can do what you want, at the cost of requesting another permission, one that prospective users might not like.

2. Handle the SecurityException and simply do without the data that you are trying to query(), if that data is not essential.

3. Write a separate app with the READ_CONTACTS permission that can serve as a "plugin" for your app, securely retrieving contact data on behalf of your main app. You can then route users who get the SecurityException to install your contacts plugin. This is tricky to write without introducing security flaws, so I would encourage you to use either of the other options.
