kandi X-RAY | volley Summary
Volley is a benchmarking tool for measuring the performance (latency in particular) of server networking stacks. It can be used to determine the performance of the lower levels of the stack (i.e. the kernel), of the server application's programming language abstractions for sockets, or of the libraries and code running within the application. Volley spawns a configurable number of concurrent clients that all connect to the server, and then performs ping-pong-like single-word operations with the server to gather statistics. It will continue doing so for as many iterations as it takes to produce statistically relevant results.

The first thing that you have to do is determine the schema of the database.
Looking at your data you have a lots of MyData objects, each of which will have 0 or more Unit objects.
Thus you could have a table for the MyData objects and table for the Unit objects. Each Unit will have a parent MyData object. So in addition to the data for each Unit you could have a column that references (maps, associates) the MyData (probably it's food_id assuming that this uniquely identifies the MyData).
Using a shortened version of MyData (just the food_id, food_name) and a shortened version of Unit (unit, amount and calory) to demonstrate then you could have two classes as:-
QUESTION
I have a .pdf file (which can change content daily, so must be downloaded daily) on my server which is downloaded to the device using Volley. The api uses authentication tokens.
I can successfully call the web service and write the pdf (byte[]) to my app's internal storage by using context.getExternalFilesDir.
The problem i am having is once the pdf is saved and i contruct the path, the webView will not show the pdf. The webView is working fine as i have done a test by placing a test html in the project's raw directory. The webView can display this fine.
The following does not load the pdf.
...ANSWER
Answered 2022-Jan-14 at 13:37well, WebView
is designed to open web pages, PDF isn't such content type... yeah, desktop browser can do it, even some mobile ones, but this is additional feature. not available in WebView
, you have to handle such file by yourself (e.g. using PdfRenderer
). another way is to use some library, first example from search engine: AndroidPdfViewer on GitHub
edit: just realised that your PDF is local only, so below probably isn't an option for you...
way simpler would be to use some web application, which can read PDF and show it as a web page, readable by WebView
. for example try to load below URL

I´ve been trying to do a GET request to my php file using Volley Library. The problem I´m having is that I can´t stablish a connection with my URL. The error I´m getting is this one: com.android.volley.AuthFailureError
This is my code:
...ANSWER
Answered 2021-Nov-26 at 04:23It´s me again. I´ve solved my problem. By default, XAMPP and WAMP Apache servers have a default configuration that doesn´t allow foreign access to your php files. The configuration can be modified in the following file (in WAMP): httpd-vhosts.conf. This is how I accessed it:
The configurations contained in the file are the following:
By default, the setting Require is setted to local. For external access, that´s what the android app needs, it´s necesary to change it to Require all granted. Therefore, this is how the config file should look: This solved the problem for me.

...ANSWER
Answered 2021-Nov-25 at 18:33As I understand it you are trying to identify all possible matches for the jumbled string in your list. You could sort the letters in the jumbled word and match the resulting list against sorted lists of the words in your data file.
