Android不显示READ_CONTACT WRITE_CONTACTS的权限请求对话框

Question

我遵循了安卓指南，为运行VERSION的安卓设备请求权限。M及以上即(运行时权限(，但没有显示权限请求对话框，而是自动拒绝权限。

我请求用户获得"读/写联系人"权限以及我下面的清单所示的其他权限。

该应用程序请求其他权限，如访问文件、电话、短信，但不请求读取联系人权限。

这是我的清单文件

<uses-permission

这是我明确的读取联系人权限请求块

private void loadDeviceContactsOnAndroid_M() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (checkSelfPermission(Manifest.permission_group.CONTACTS) == PackageManager.PERMISSION_GRANTED) {
Log.e(getClass().getSimpleName(), "Read contacts permission granted");
loadAndDisplayConfiguredRecipients();
} else {
Log.e(getClass().getSimpleName(), "Read contacts permission Not granted");
if (shouldShowRequestPermissionRationale(Manifest.permission_group.CONTACTS)) {
Toast.makeText(getApplicationContext(), "mPHR messaging feature requires your contacts", Toast.LENGTH_LONG).show();
}
ActivityCompat.requestPermissions(this,new String[]{Manifest.permission_group.CONTACTS}, 101);
}
} else
Toast.makeText(getApplicationContext(), "Android Version is " + Build.VERSION.SDK_INT, Toast.LENGTH_LONG).show();
}

这是我的onRequestPermissionResult回调方法

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
if (requestCode == 101) {
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Toast.makeText(this, "Hurray permission granted ", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(this, "Until you grant the permission, we cannot display the names", Toast.LENGTH_SHORT).show();
}
}
}

这是我的联系人加载程序方法块

Cursor cursor = contactController.querySystemContacts("");
if (cursor.moveToFirst()) {
do {
String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
messageRecipients.add(name);
} while (cursor.moveToNext());
}
cursor.close();

该应用程序不会向用户请求联系人权限，当我绕过此权限并尝试继续访问设备上的联系人时，我得到了拒绝权限的安全错误；

java.lang.SecurityException: Permission Denial: opening provider com.android.providers.contacts.ContactsProvider2 from ProcessRecord{13c53b7 14017:my/app/package/name/u0a183} 
(pid=159017, uid=10183) 
requires android.permission.READ_CONTACTS or android.permission.WRITE_CONTACTS

我正在安卓8物理设备上运行测试。

当我使用相同的代码时，例如，ACCESS_COARSE_LOCATION_PERMISSION，它工作得很好，但当我使用READ_CONTACT或WRITE_CONTACTS 时失败

我没有尝试过你的代码，但请不要直接使用checkSelfPermission。按照谷歌的建议，使用ContextCompat.checkSelfPermission方法。

if (ContextCompat.checkSelfPermission(thisActivity, Manifest.permission.WRITE_CALENDAR)
!= PackageManager.PERMISSION_GRANTED) {
// Permission is not granted
}

https://developer.android.com/training/permissions/requesting#java

当我添加权限检查代码时，我是单独进行权限检查的，这意味着我是逐个检查权限，而不是检查权限组。所以我稍后会试试。但目前，请尝试使用ContextCompat方法。

编辑：

请不要按权限组进行请求。安卓M中的权限请求模型仅适用于个人权限。以下是你能做的。

private void checkPermission() {
if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED
|| ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_CONTACTS) != PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.READ_CONTACTS) || ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.WRITE_CONTACTS)) {
Toast.makeText(this, "Necessary permissions are not granted",
Toast.LENGTH_LONG).show();
} else {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.READ_CONTACTS, Manifest.permission.WRITE_CONTACTS},
MY_PERMISSIONS_REQUEST_CODE);
}
} else {
// Permission has already been granted
}
}

编辑：

请不要在您的清单中使用以下内容。

<uses-permission android:name="Manifest.permission.READ_CONTACTS"
tools:remove="android:maxSdkVersion"/>
<uses-permission android:name="Manifest.permission.WRITE_CONTACTS"
tools:remove="android:maxSdkVersion"/>
<uses-permission android:name="Manifest.permission.CONTACTS"/>

您可以用以下内容替换它们。

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

Answer 2

您可以在需要使用应用程序或运行时请求权限。试试这个库(https://github.com/nabinbhandari/Android-Permissions)。它为您提供了很多选项，比如当用户拒绝或授予权限时，您还可以请求多个权限。

示例

单一权限

Permissions.check(this/*context*/, Manifest.permission.READ_CONTACTS, null, new PermissionHandler() {
@Override
public void onGranted() {
// do your task.
}});

多重权限

String[] permissions = {Manifest.permission.READ_CONTACTS, Manifest.permission.WRITE_EXTERNAL_STORAGE};Permissions.check(this/*context*/, permissions, null/*rationale*/, null/*options*/, new PermissionHandler() {
@Override
public void onGranted() {
// do your task.
}});

注意使用库不是一个好的做法，除非它们得到了良好的维护
