Multiple Permission at once not working in android

I am trying to get 2 permissions at once but Iam unable to do so.

if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {

    if (ContextCompat.checkSelfPermission(context, Manifest.permission.READ_CONTACTS)
                != PackageManager.PERMISSION_GRANTED) {

        ActivityCompat.requestPermissions(context, Array<String>(2) { 
            Manifest.permission.READ_CONTACTS; 
            Manifest.permission.WRITE_EXTERNAL_STORAGE},
        1);
    }
}

It only asks for WRITE_EXTERNAL_STORAGE permission and not READ_CONTACTS. Actually, If I write WRITE_EXTERNAL_STORAGE one first and READ_CONTACTS after that then it will only ask for contact and not WRITE_EXTERNAL_STORAGE.

Array(size: Int, init: (Int) -> T)

is the constructor for the Array class which takes the number of elements it should contain, and an init function which maps the index to an actual array element.

Here is what your code does, written in a more verbose way

val a = Array<String>(size = 2, init = { index: Int ->
    Manifest.permission.READ_CONTACTS; // nothing
    Manifest.permission.WRITE_EXTERNAL_STORAGE // returned by the lambda for each index
})

Result:

[Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE]

So, you would be better of using the arrayOf function in this case, since you don't want to genereate your array elements but rather specify them explicitely.

Use this code for multiple permission in kotlin

 ActivityCompat.requestPermissions(context as Activity,
                                arrayOf(Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE),
                                PERMISSION_CAMER)

Array<String>(2) { 
    Manifest.permission.READ_CONTACTS ; 
    Manifest.permission.WRITE_EXTERNAL_STORAGE
}

This initializer always returns WRITE_EXTERNAL_STORAGE, the first line does not do anything. You should probably be using the arrayOf function to construct the array instead.
