I am currently working on an application that requires several \"dangerous\" permissions. So I tried adding \"ask for permission\" as required in Android Marshmallow(API Lev

    For multiple permission at a time you can use this. This work for me.. I got another solution. if you give your targetSdkVersion bellow 22 it works for me. and it behavior as like getting permission from manifest.xml. Tested and works for me.

    final private int REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS = 124;
    
        private void insertDummyContactWrapper() {
            List permissionsNeeded = new ArrayList();
    
            final List permissionsList = new ArrayList();
            if (!addPermission(permissionsList, Manifest.permission.ACCESS_FINE_LOCATION))
                permissionsNeeded.add("GPS");
            if (!addPermission(permissionsList, Manifest.permission.READ_CONTACTS))
                permissionsNeeded.add("Read Contacts");
            if (!addPermission(permissionsList, Manifest.permission.WRITE_CONTACTS))
                permissionsNeeded.add("Write Contacts");
    
            if (permissionsList.size() > 0) {
                if (permissionsNeeded.size() > 0) {
                    // Need Rationale
                    String message = "You need to grant access to " + permissionsNeeded.get(0);
                    for (int i = 1; i < permissionsNeeded.size(); i++)
                        message = message + ", " + permissionsNeeded.get(i);
                    showMessageOKCancel(message,
                            new DialogInterface.OnClickListener() {
                                @Override
                                public void onClick(DialogInterface dialog, int which) {
                                    requestPermissions(permissionsList.toArray(new String[permissionsList.size()]),
                                            REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS);
                                }
                            });
                    return;
                }
                requestPermissions(permissionsList.toArray(new String[permissionsList.size()]),
                        REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS);
                return;
            }
    
            insertDummyContact();
        }
    
        private boolean addPermission(List permissionsList, String permission) {
            if (checkSelfPermission(permission) != PackageManager.PERMISSION_GRANTED) {
                permissionsList.add(permission);
                // Check for Rationale Option
                if (!shouldShowRequestPermissionRationale(permission))
                    return false;
            }
            return true;
        }
    
    
    
    
    
    
    @Override
        public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
            switch (requestCode) {
                case REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS:
                    {
                    Map perms = new HashMap();
                    // Initial
                    perms.put(Manifest.permission.ACCESS_FINE_LOCATION, PackageManager.PERMISSION_GRANTED);
                    perms.put(Manifest.permission.READ_CONTACTS, PackageManager.PERMISSION_GRANTED);
                    perms.put(Manifest.permission.WRITE_CONTACTS, PackageManager.PERMISSION_GRANTED);
                    // Fill with results
                    for (int i = 0; i < permissions.length; i++)
                        perms.put(permissions[i], grantResults[i]);
                    // Check for ACCESS_FINE_LOCATION
                    if (perms.get(Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED
                            && perms.get(Manifest.permission.READ_CONTACTS) == PackageManager.PERMISSION_GRANTED
                            && perms.get(Manifest.permission.WRITE_CONTACTS) == PackageManager.PERMISSION_GRANTED) {
                        // All Permissions Granted
                        insertDummyContact();
                    } else {
                        // Permission Denied
                        Toast.makeText(MainActivity.this, "Some Permission is Denied", Toast.LENGTH_SHORT)
                                .show();
                    }
                    }
                    break;
                default:
                    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
            }
        }
