Trying to get the text of the post VK.

VKRequest request = VKApi.wall().get(VKParameters.from(VKApiConst.OWNER_ID,-****,VKApiConst.EXTENDED,0,VKApiConst.COUNT,1,VKApiConst.FIELDS,"text")); request.executeWithListener(new VKRequest.VKRequestListener() { @Override public void onComplete(VKResponse response) { VKList<VKApiPost> posts = (VKList<VKApiPost>) response.parsedModel; VKApiPost post = posts.get(0); Log.d("Post:", post.toString()); String textpost = post.text; TextView textView = findViewById(R.id.myText); textView.setText(textpost); } });

The error takes off:

Similar request

 VKRequest request = VKApi.friends().get(VKParameters.from(VKApiConst.FIELDS,"first_name,last_name"));

passes without errors.

As I understand it, the request for posts comes up empty.

I checked the parameters on https://vk.com/dev/wall.get , there is an answer.

Tell me, please, what is the problem

    You use the VKApiConst.FIELDS parameter. The documentation says: Обратите внимание, этот параметр учитывается только при extended=1 . You have it is zero. Your request should look like this:

     VKRequest request = VKApi.wall().get(VKParameters.from(VKApiConst.OWNER_ID,-****,VKApiConst.EXTENDED,1,VKApiConst.COUNT,1,VKApiConst.FIELDS,"text"));
