Answer 1

That is the request code you need to pass to the request permisson method,
once user grants/deny the permissions,call back method 
onRequestPermissionsResult will be called with permission result.  
public static final int REQUEST_PERMISSIONS = 100;//Any integer

ActivityCompat.requestPermissions(MainActivity1.this,
new String[]{Manifest.permission .WRITE_EXTERNAL_STORAGE, 
Manifest.permission.READ_CONTACTS}, REQUEST_PERMISSIONS);
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, 
@NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (grantResults.length > 0
&& grantResults[0] == PackageManager.REQUEST_PERMISSIONS) {
goToCamera(null);
} else {
// permission denied, boo! Disable the
// functionality that depends on this permission.
}
}

REQUEST_PERMISSIONS是一个整数值，用于指定某些权限的请求代码。在您的活动顶部写下以下行。

private static final int REQUEST_PERMISSIONS=1232;//This can be any integer value and field name can also be changed
