Android marshmallow request permission?

Question

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);
        }
    }
