Kotlin - Can not access <uses-permision> in AndroidManifest file to make permission request

I'm trying to request permission to use the READ_EXTERNAL_STORAGE and WRITE_EXTERNAL_STORAGE but when I add them to the AndroidManifest file like so, I am not able to call them from my activity when I go to request permission:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
if I add the following request to my MainActivity I get an error on the names of the permissions:
ActivityCompat.requestPermissions(this,
arrayOf(Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_EXTERNAL_STORAGE), RQ_PERMISSION)
However, if I have them in the manifest like this, there is no error but the permissions don't get requested.
<permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
What am I doing wrong?

Make sure that you have import android.Manifest or can use
ActivityCompat.requestPermissions(this,
arrayOf(android.Manifest.permission.WRITE_EXTERNAL_STORAGE, android.Manifest.permission.READ_EXTERNAL_STORAGE), RQ_PERMISSION)

XIAOMI MI4W with android 6.0.1 not set SMS_READ permission by programmatically

I'm setting up permission in Manifest file
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.VIBRATE"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.RECEIVE_SMS"/>
<uses-permission android:name="android.permission.READ_SMS" />
But unfortunatly I can't get SMS permissin, after I setted up application, I should go to security property of smartphone and set it by myself. What the reason, is it reason of MI restrictions or I must set somthing else in 6 version of Android. This worked on previos version on this smartphone.

From Android marshmallow you need to give run time permission.
Add below given code in your launch activity onCreate() method.
String permission = Manifest.permission.READ_SMS;
if (ContextCompat.checkSelfPermission(getContext(), permission) != PackageManager.PERMISSION_GRANTED){
permissionList.add(permission);
if (!ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), permission)){
requestPermissions(new String[]{permission}), SMS_PERMISSION);
}
}

Android Uses-Feature VS. Uses-Permision Optimization

I have the following permissions explicitly requested in my manifest.
I would like to optimize store visibility by switching as many as possible of them to implicit 'uses-feature' declarations. I will also handle this additionally in code checking for features before I access them.
Internet access is the only thing that's truly required for my app, other features I can enable/disable conditionally based on hasFeatures().
Question:
Which of these permissions can I change?
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.VIBRATE"/>
<uses-permission android:name="com.android.vending.BILLING" />
<permission android:name="com.appName.supportmapfragment.permission.MAPS_RECEIVE" android:protectionLevel="signature"/>
<uses-permission android:name="com.appName.supportmapfragment.permission.MAPS_RECEIVE"/>
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<uses-feature android:glEsVersion="0x00020000" android:required="true" />

Set required to 'false' if your app doesn't require something to run:
To control filtering, always explicitly declare hardware features in
elements, rather than relying on Google Play to
"discover" the requirements in elements. Then, if
you want to disable filtering for a particular feature, you can add a
android:required="false" attribute to the declaration.
http://developer.android.com/guide/topics/manifest/uses-permission-element.html (in the right-hand sidebar)
The documentation has this example:
<uses-feature android:name="android.hardware.camera" android:required="false" />

Phone call function intent not working in android

I have made a simple app,In that i want to make a phone call on click of a text view,But I am getting an exception that "No activity found that can do this action"..I have tried a lot and gives all permission to manifest,But still having the same error".
main.java
Intent dialer = new Intent(Intent.ACTION_CALL,
Uri.parse("9033309332"));
startActivity(dialer);
manifest.xml
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.CALL_PRIVILEGED" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.INTERACT_ACROSS_USERS_FULL" />

Try to use this code.
Intent callIntent = new Intent(Intent.ACTION_DIAL);
callIntent.setData(Uri.parse("tel:9033309332"));
startActivity(callIntent);

I also had the same problem. Most probably it may be because our device grant the permission to that app then it may work. Just go to settings and grant the permission.

Android - Simple permissions - Why don't I need this permission?

I'm currently working images using
mBitmap = BitmapFactory.decodeFile(filePath);
ExifInterface exif = new ExifInterface(filePath);
My permissions are:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
I thought I needed a read storage permission to get the files from the gallery. Why can I access files from my Gallery without this permission?
If it helps, I'm using the ACTION_SEND intent filter to start the activity via a "Share" dialog.
Edit: Just to clarify, my application works perfectly. I thought I would need a special permission to read files from the SD card (such as images). Is this not the case?

this is
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
