我正在尝试从联系人ACTION_PICK意图名称，电话号码和照片返回的联系人中访问许多内容。检索姓名和电话号码没有问题，但是当我尝试访问照片时，我每次都会收到SecurityException，并说明需要GLOBAL_SEARCH权限。这是logcat ......
Caused by: java.lang.SecurityException: Permission Denial: reading com.android.providers.contacts.ContactsProvider2 uri content://com.android.contacts/contacts/14/photo from pid=4526, uid=10223 requires android.permission.GLOBAL_SEARCH, or grantUriPermission()
我已经梳理了stackoverflow并尝试了我发现的每一种方法，并且作为一项完整性检查我现在正在使用谷歌推荐的方法，如下所示
public InputStream retrieveContactPhoto() {
Uri contactUri = ContentUris.withAppendedId(Contacts.CONTENT_URI, Long.valueOf(mContactID));
Uri photoUri = Uri.withAppendedPath(contactUri, Contacts.Photo.CONTENT_DIRECTORY);
Cursor cursor = getContentResolver().query(photoUri,
new String[] {Contacts.Photo.PHOTO}, null, null, null);
if (cursor == null) {
return null;
}
try {
if (cursor.moveToFirst()) {
byte[] data = cursor.getBlob(0);
if (data != null) {
return new ByteArrayInputStream(data);
}
}
} finally {
cursor.close();
}
return null;
}
但是，我在每种情况下都得到相同的SecurityException。它在contentResolver查询行中抛出。显然，没有办法获得GLOBAL_READ权限，所以我不太清楚如何解决这个问题。 此外，由于我能够毫无问题地检索姓名和电话号码，我无法想象我是如何创建意图的，但是为了完整性，这是startActivityForResult（）调用
Intent contactIntent = new Intent(Intent.ACTION_PICK, Contacts.CONTENT_URI);
startActivityForResult(contactIntent, INTERVIEWEE_FROM_CONTACTS);
我已经浏览过互联网，无法找到有人接收此SecurityException的案例，我所看到的只是需要READ_CONTACTS和WRITE_CONTACTS权限的应用，因此我确信我和忽略了一些显而易见的东西，但我只是完全被难倒了。我在运行Nougat的Nexus 6p上进行测试。 请帮忙！

您通过以下方式检查是否授予了权限：
checkSelfPermission(Manifest.permission.READ_CONTACTS)
必要时请求权限
if (checkSelfPermission(Manifest.permission.READ_CONTACTS)
!= PackageManager.PERMISSION_GRANTED) {
requestPermissions(new String[]{Manifest.permission.READ_CONTACTS},
MY_PERMISSIONS_REQUEST_READ_CONTACTS);
// MY_PERMISSIONS_REQUEST_READ_CONTACTS is an
// app-defined int constant
return;
}
处理权限请求响应
public void onRequestPermissionsResult(int requestCode,
String permissions[], int[] grantResults) {
switch (requestCode) {
case MY_PERMISSIONS_REQUEST_READ_CONTACTS: {
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// permission was granted, yay! do the
// calendar task you need to do.
} else {
// permission denied, boo! Disable the
// functionality that depends on this permission.
}
return;
}
// other 'switch' lines to check for other
// permissions this app might request
}
}
