Is it possible to recover classes from apk or through Android Studio?


Is it possible to recover classes from apk or through Android Studio?



I made an ironically horrible mistake while trying to backup my android project, and managed to almost destroy it with a botched up "move".



I am trying to recover the code from my classes. the project was fairly simple. I tried using dex2jar and then jd-gui on the .apk I have installed on my phone but I don't seem to be getting the same results other people are getting. There's nothing remotely close to my classes on the end product.



Is there a way to recover my code? Either through reverse engineering or maybe Android Studio has some sort of function where it keeps code in a temp file or something?





try search in local history. Similar to stackoverflow.com/questions/30049250/…

Wow local history seems great. I moved my project back to its original location and used local history on all the classes to revert to last changes. However after I click revert , all the class files I just reverted seem to disappear. Where do they go? If I can find them and they have successfully reverted then you saved my life dude. @peter

Recovered code would be very ugly. Comments and variable names within methods can't be recovered, because they were discarded once compiled. It is possible but if you can recover deleted code files from your disk that would be much better.

Reverse Engineering is overly complicated for recovering code in my opinion. I'm not sure how "move" command works, but you might be able to recover the files with a program dedicated to recovering lost/deleted files. Pori form has a program for that for example, but it's hard recovering if the files got overwritten and not deleted or something.



Maybe you've made some backups yourself somewhere?



The question is how much time and work you are willing to put into getting exactly your code back, because if simple recovery methods don't work you might be faster just rewriting your code, but it really depends on the project size.

api-platform.com Unable to generate an IRI for the item of type

api-platform.com Unable to generate an IRI for the item of type I'm trying to setup my first api-platform instance and have run into some presumably noob questions around IDE. What i'm trying to do is setting up an register and reset entity in order to deal with registrations and password reminders from an app. And then have the entity's passed to a custom controller to do some checks, balances and mails afterwards (haven’t gotten around to that yet). But I keep running into this error when posting to my custom entities: { "@context": "/api/contexts/Error", "@type": "hydra:Error", "hydra:title": "An error occurred", "hydra:description": "Unable to generate an IRI for the item of type "AppXXXUserBundleEntityRegister"", "trace": [ { "namespace": "", "short_class": "", "c

PHP contact form sending but not receiving emails

PHP contact form sending but not receiving emails I have created a contact form using PHP to send the data. The form seems to send fine as there are no errors and success message appears, however I am not receving the emails into the designated inbox. I am using PHPMailer as I originally tried just using the php 'mail' command which I now understand is a bit hit and miss. I cannot see why I would not be receving the emails so I would be very grateful for any help that could be given. I'm quite new to PHP so please be patient with me :) <?php use PHPMailerPHPMailerPHPMailer; use PHPMailerPHPMailerException; $msg = ""; if (isset($_POST['submit'])) { require 'phpmailer/src/Exception.php'; require 'phpmailer/src/PHPMailer.php'; require 'phpmailer/src/SMTP.php'; function sendemail ($to, $from, $body) { $mail = new PHPMailer(true); $mail->setFrom($from); $mail->addAddress($to); $ma

Do graphics cards have individual ID by which single devices can be distinguished?

Do graphics cards have individual ID by which single devices can be distinguished? I have several graphics cards of the same manufacturer and same model and I want to distinguish them not only by the pcie socket they reside in but by some individual value I can read from the hardware. Is there such value and if so what would it be called and how could I access it? Right now I'm using modern nvidia cards (10xx series) and nvidia inspector.but I'd prefer if there was any value that was also applicable to amd. I have programming and scripting knowledge. I am running Windows 10 1 Answer 1 This is a powershell example to pull information from video cards. The DeviceID is supposed to be unique but only if the manufacturer supports Windows Display Driver Model (WDDM).
