Calling ActivityCompat.requestPermissions does not display the UI dialog box.
ActivityCompat.requestPermissions(MainActivity.this, new String[]{"Manifest.permission.READ_SMS"}, REQUEST_CODE_ASK_PERMISSIONS);
However, if I change the minSDKversion to 23 and run
requestPermissions(new String[]{"android.permission.READ_SMS"}, REQUEST_CODE_ASK_PERMISSIONS);
the dialog appears. Why? BTW. to run it on the emulator requires that the emulator will be targeting API 23.

Sets the permission delegate for ActivityCompat . Gets whether you should show UI with rationale before requesting a permission. Start new activity with options, if able, for which you would like a result when it finished. Start new IntentSender with options, if able, for which you would like a result when it finished.
shouldShowRequestPermissionRationale return the boolean indicating whether or not we should show UI with rationale for requesting a permission (dangerous permission, ACCESS_FINE_LOCATION) Now in this code (taken from the documentation itself) : if (ContextCompat. checkSelfPermission(thisActivity, Manifest. permission.
Here's an example of using requestPermissions (): First, define the permission (as you did in your post) in the manifest, otherwise, your request will automatically be denied: Next, define a value to handle the permission callback, in onRequestPermissionsResult ():
Android provides several methods that can be used to request permission, such as requestPermissions (). ActivityCompat. requestPermissions (MainActivity.this, permissionArray, requestCode); Here permissionArray is an array of type String.
To display the system permissions dialog when necessary, call the launch () method on the instance of ActivityResultLauncher that you saved in the previous step. After launch () is called, the system permissions dialog appears.
If you want to request the permissions specific to call logs and SMS messages and publish your app to the Play Store, you must prompt the user to set your app as the default handler for a core system function before requesting these runtime permissions.
Why?
Probably because you have the wrong permission name in the first code snippet. Either use:
Manifest.permission.READ_SMS
or use:
"android.permission.READ_SMS"
Do not use:
"Manifest.permission.READ_SMS"
