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

Answer 1

Android-M ie, API 23 introduced Runtime Permissions for reducing security flaws in android device, where users can now directly manage app permissions at runtime.so if the user denies a particular permission of your application you have to obtain it by asking the permission dialog that you mentioned in your query.

So check before action ie, check you have permission to access the resource link and if your application doesn't have that particular permission you can request the permission link and handle the the permissions request response like below.

@Override
public void onRequestPermissionsResult(int requestCode,
        String permissions[], int[] grantResults) {
    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_READ_CONTACTS: {
            // If request is cancelled, the result arrays are empty.
            if (grantResults.length > 0
                && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                // permission was granted, yay! Do the
                // contacts-related task you need to do.

               } else {

                // permission denied, boo! Disable the
                // functionality that depends on this permission.
            }
            return;
        }

        // other 'case' lines to check for other
        // permissions this app might request
    }
}

So finally, It's a good practice to go through behavior changes if you are planning to work with new versions to avoid force closes :)
