How to Use

• First

You nees decelar the permission what you need in your "AndroidManifest.xml" file. like

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.CAMERA" />

• Request the permissions which you need

• 申请你所需要的权限

         //ask camera permission
        PermissionHandler.requestPermission(this, AppPermission.CAMERA.INSTANCE);

        //ask storage permission
        PermissionHandler.requestPermission(this, AppPermission.READ_EXTERNAL_STORAGE.INSTANCE);

• In the permissions dialog of the system,listen the click event of user

• 在系统的权限申请弹窗中，监听用户的点击事件

if you do this, the first thing what you need to do is that overrive the onRequestPermissionsResult funtion ,like this

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {

        PermissionHandler.onRequestPermissionsResultReceived(requestCode, permissions, grantResults, appPermissionGranted -> {

            Toast.makeText(this, " Permission Granted", Toast.LENGTH_SHORT).show();
            // you select granted
            return null;

        }, appPermissionDenied -> {

            Toast.makeText(this, " Permission Defined", Toast.LENGTH_SHORT).show();
            // you select  defined
            return null;
        });


    }

• Check to see if you have the permissions what you need

• 检查是否拥有你所需要的权限

here is some code what check camera permsiion, storage permission..so on

   private void checkCameraPermission() {

        PermissionHandler.checkPermission(this, AppPermission.CAMERA.INSTANCE,

                //this permission was granted already
                granted -> {
                    Toast.makeText(this, "Camera Permission Granted", Toast.LENGTH_SHORT).show();
                    return null;
                },
                //this permission was denied already
                denied -> {
                    Toast.makeText(this, "Camera Permission Denied", Toast.LENGTH_SHORT).show();
                    return null;
                },

                //user select dot not ask again already
                rationale -> {
                    Toast.makeText(this, "Camera Permission Not Ask Again", Toast.LENGTH_SHORT).show();
                    return null;
                });
    }

    private void checkStoragePermission() {
        PermissionHandler.checkPermission(this, AppPermission.READ_EXTERNAL_STORAGE.INSTANCE,

                //this permission was granted already
                granted -> {
                    Toast.makeText(this, "Storage Permission Granted", Toast.LENGTH_SHORT).show();
                    return null;
                },
                //this permission was denied already
                denied -> {
                    Toast.makeText(this, "Storage PermissionDenied", Toast.LENGTH_SHORT).show();
                    return null;
                },

                //user select dot not ask again already
                rationale -> {
                    Toast.makeText(this, "Storage Permission Not Ask Again", Toast.LENGTH_SHORT).show();
