Camera Permission programatically

In newer version android needs types of permission that user need to ask user to allow , here i will show you one of the Camera permission that how we can use in android programatically.

First you have to add permission in Menifest.xml file

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

Below code you have to add where you want to ask for permission for Camera.

ActivityCompat.requestPermissions(MainActivity.this,new String[]{Manifest.permission.CAMERA},

1);

Then the below code you have to put.

@Overridepublic void onRequestPermissionsResult(int requestCode,
                                       String permissions[], int[] grantResults) {
    switch (requestCode) {
        case 1: {

            // If request is cancelled, the result are empty.            

if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                // permission was granted,  Do the code
               
            } else {

                // permission denied, 
                Toast.makeText(MainActivity.this, 

"Permission denied to read your External storage", Toast.LENGTH_SHORT).show();
            }
            return;
        }

    }
}
