How to ask multiple permissions at the same time in android 6.0+

Question

i want to ask the user to accept the following permissions at the same time(one by one), the permissions are like: checkLocationPermission, checkReadSMS, checkCallingPermission, checkReadState, checkContactWriteState. So, how i can ask all these permissions in my first screen itself. Please help me out in this regard. Thanks in advance.

You have to first check that user phone build version is 23.

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    askPermissions(true);
} else {
    startActivity(new Intent(PermissionsActivity.this, SplashActivity.class));
    finish();
}

If version is 23 then you need to ask permissions.

private void askPermissions(boolean isForOpen) {
    isRationale = false;
    List permissionsRequired = new ArrayList();

    final List<String> permissionsList = new ArrayList<String>();
    if (!checkPermission(permissionsList, Manifest.permission.WRITE_EXTERNAL_STORAGE))
        permissionsRequired.add("Write External Storage");
    if (!checkPermission(permissionsList, Manifest.permission.CALL_PHONE))
        permissionsRequired.add("Call phone");
    if (!checkPermission(permissionsList, Manifest.permission.READ_PHONE_STATE))
        permissionsRequired.add("Read phone state");
    if (!checkPermission(permissionsList, Manifest.permission.READ_CONTACTS))
        permissionsRequired.add("Read Contacts");
    if (!checkPermission(permissionsList, Manifest.permission.RECEIVE_SMS))
        permissionsRequired.add("Receive SMS");
    if (!checkPermission(permissionsList, Manifest.permission.GET_ACCOUNTS))
        permissionsRequired.add("Get Accounts");
    if (!checkPermission(permissionsList, Manifest.permission.ACCESS_COARSE_LOCATION))
        permissionsRequired.add("Location");
    if (!checkPermission(permissionsList, Manifest.permission.ACCESS_FINE_LOCATION))
        permissionsRequired.add("Location");

    if (permissionsList.size() > 0 && !isRationale) {
        if (permissionsRequired.size() > 0) {

        }
        if (isForOpen) {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                ActivityCompat.requestPermissions(this, permissionsList.toArray(new String[permissionsList.size()]),
                        11);
            }
        }

    } else if (isRationale) {
        if (isForOpen) {

            new android.support.v7.app.AlertDialog.Builder(this, R.style.AppCompatAlertDialogStyle)
                    .setTitle("Permission Alert")
                    .setMessage("You need to grant permissions manually. Go to permission and grant all permissions.")
                    .setPositiveButton("OK", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            dialog.dismiss();
                            Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
                            Uri uri = Uri.fromParts("package", getPackageName(), null);
                            intent.setData(uri);
                            startActivityForResult(intent, 123);
                        }
                    })
                    .show();
        }
    } else {
        startActivity(new Intent(PermissionsActivity.this, SplashActivity.class));
        finish();
    }
}

private boolean checkPermission(List permissionsList, String permission) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        if (ContextCompat.checkSelfPermission(this, permission) != PackageManager.PERMISSION_GRANTED) {
            permissionsList.add(permission);
            // Check for Rationale Option
            if (!isFirst) {
                if (!ActivityCompat.shouldShowRequestPermissionRationale(this, permission)) {
                    isRationale = true;
                    return false;
                }
            }
        }
    }
    return true;
}

on the onRequestPermissionsResult you need to check which permissions granted

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    switch (requestCode) {
        case 11:
            Map<String, Integer> perms = new HashMap<String, Integer>();
            // Initial
            perms.put(Manifest.permission.WRITE_EXTERNAL_STORAGE, PackageManager.PERMISSION_GRANTED);
            perms.put(Manifest.permission.CALL_PHONE, PackageManager.PERMISSION_GRANTED);
            perms.put(Manifest.permission.READ_PHONE_STATE, PackageManager.PERMISSION_GRANTED);
            perms.put(Manifest.permission.READ_CONTACTS, PackageManager.PERMISSION_GRANTED);
            perms.put(Manifest.permission.RECEIVE_SMS, 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.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED &&
                    perms.get(Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED &&
                    perms.get(Manifest.permission.READ_PHONE_STATE) == PackageManager.PERMISSION_GRANTED &&
                    perms.get(Manifest.permission.READ_CONTACTS) == PackageManager.PERMISSION_GRANTED &&
                    perms.get(Manifest.permission.RECEIVE_SMS) == PackageManager.PERMISSION_GRANTED) {
                // All Permissions Granted
                startActivity(new Intent(PermissionsActivity.this, SplashActivity.class));
                finish();
            } else {
                // Permission Denied
                Toast.makeText(this, "Some Permission is Denied.", Toast.LENGTH_SHORT)
                        .show();
                isFirst = false;
                askPermissions(true);
            }
            break;
        default:
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);

    }
}

If user has set the permission to never ask again then the application setting screen will open. User will allow/Deny permission there. You need to check again on the activityResult.

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    askPermissions(true);
}
