How to check android application permissions on runtime using ContextCompat.checkSelfPermission()?

Question

Need to check for the grant of the required permissions(specifically to read user device sms)by the android application user as per android 6 and above standards. I am specifically looking for the ContextCompat.checkSelfPermission() method described on android developer site. See here: link

Please follow this tutorials Here is complete source code

static final int PERMISSION_ALL = 1;
    String[] PERMISSIONS =
            {Manifest.permission.ACCESS_COARSE_LOCATION,
                    Manifest.permission.ACCESS_FINE_LOCATION};

     protected void runtimePermission() {
        if (!hasPermission(ContactUS.this, PERMISSIONS)) {
            ActivityCompat.requestPermissions(this, PERMISSIONS, PERMISSION_ALL);
        }
    }

    public static boolean hasPermission(Context context, String... permissions) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null) {
            for (String permission : permissions) {
                if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
                    return false;
                }

            }
        }
        return true;
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        switch (requestCode) {
            case PERMISSION_ALL:
                if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    //permission granted
                    //your logic here
                } else {
                    //permission denied
                }
                break;

        }
    }

you can add run time permission like this follow this steps

step 1 :- first add this permission in manifiest file

android.Manifest.permission.ACCESS_FINE_LOCATION,
android.Manifest.permission.ACCESS_COARSE_LOCATION,

now, than

step 2 : ask runtime permission

String permission = android.Manifest.permission.ACCESS_FINE_LOCATION;
        if (ActivityCompat.checkSelfPermission(SearchCityClass.this, permission)
                != PackageManager.PERMISSION_GRANTED && ActivityCompat.
                checkSelfPermission(SearchCityClass.this, android.Manifest.permission.ACCESS_COARSE_LOCATION)
                != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(SearchCityClass.this, new String[]
                    {permission}, PERMISSION_GPS_CODE);

        }

step 3: finallly handle permsiion result in onRequestPermissionsResult

 @Override
 public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
                                   @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == PERMISSION_GPS_CODE) {
    if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {


        Toast.makeText(this, location_permission_granted_msg, Toast.LENGTH_SHORT).show();

    } else {

        Toast.makeText(this, location_permission_not_granted_msg, Toast.LENGTH_SHORT).show();
    }
}

}

if the permission is granted by :

checkSelfPermission(Manifest.permission.READ_CONTACTS)

Request permissions if necessary

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;
    }

Handle the permissions request response

@Override
public void onRequestPermissionsResult(int requestCode,
        String permissions[], int[] grantResults) {
    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_READ_CONTACTS: {
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                /* permission granted */

            } else {

                /* permission denied */
            }
            return;
        }

        /* check for other permissions */
    }
}

Also you can use a library like this, anyway good luck!
