我需要从XAML应用程序内部创建一个新的 private void askForPermission(String permission, Integer requestCode) {

// Should we show an explanation?
if (ActivityCompat.shouldShowRequestPermissionRationale(Main2Activity.this, permission)) {
//This is called if user has denied the permission before
//In this case I am just asking the permission again
ActivityCompat.requestPermissions(Main2Activity.this, new String[]{permission}, requestCode);
} else {
deviceSetting(getApplicationContext());
ActivityCompat.requestPermissions(Main2Activity.this, new String[]{permission}, requestCode);
}
} else {
deviceSetting(getApplicationContext());
Toast.makeText(this, "" + permission + " is already granted.", Toast.LENGTH_SHORT).show();
}
}
private void deviceSetting(Context context) {
GoogleApiClient googleApiClient = new GoogleApiClient.Builder(context)
.addApi(LocationServices.API).build();
googleApiClient.connect();

locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
locationRequest.setInterval(10000);
locationRequest.setFastestInterval(10000 / 2);

builder.setAlwaysShow(true);
PendingResult<LocationSettingsResult> result = LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build());

，因为我想使用CoreWindow为其分配交换链。
我不将IDXGIFactory2::CreateSwapChainForCoreWindow与SwapchainPanel结合使用的原因是因为Nvidia Nsight之类的工具无法识别我的窗口。 PIX是唯一可以与IDXGIFactory2::CreateSwapChainForComposition一起使用的图形调试器。
