Android应用程序在getContentResolver（）。查询时崩溃

请查找附加代码以检索来电的联系人姓名。在这里，我将数字硬编码为“123”。我已在模拟器中添加了此联系人。但是应用程序在getContentResolver（）。查询时崩溃了。请帮忙。

    String number = "123";
 // define the columns I want the query to return
    String[] projection = new String[] {
            ContactsContract.PhoneLookup.DISPLAY_NAME,
            ContactsContract.PhoneLookup.NUMBER };

    // encode the phone number and build the filter URI
    Uri contactUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));

    // query time
    Cursor c = getContentResolver().query(contactUri, projection, null,
            null, null);

    // if the query returns 1 or more results
    // return the first result
    if (c.moveToFirst()) {
        String name = c.getString(c
                .getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME));
        Log.i("Map", "Contact Name " + name);
    }

答案 0 :(得分：2)

ERROR/DatabaseUtils(145): java.lang.SecurityException: Permission Denial: reading
com.android.providers.contacts.ContactsProvider2 uri
content://com.android.contacts/phone_lookup/9895318420 from pid=406, uid=10024 requires
android.permission.READ_CONTACTS

解决方案正好在您发布的错误日志中。将权限READ_CONTACTS添加到您的AndroidManifest您还需要一些其他相关权限，请查看文档以查看内容。 - 您需要的将取决于您如何使用API​​。

答案 1 :(得分：1)

你能从logcat提供日志输出吗？ 您需要一个上下文来调用getContentResolver（）。您是在活动类或其他地方调用此方法吗？

编辑：您需要添加权限才能从手机的地址簿中读取联系人。请点击此链接： http://developer.android.com/reference/android/Manifest.permission.html#READ_CONTACTS
