The source code cannot be disclosed if it tried to ensure security (especially if it is a branded thing).

But there are ways to fully or partially uncover the code.

• Ida Pro is the best of free hackers, some macros may allow you to convert the code back. But not always. Borland products are particularly revealed.
• Hiew.exe. free utility, very small, allows you to edit the code in the assembler language. You can rule text and entire constants. It is possible to even make the "translation" program to another language, to lose the name of the company, etc.
• If there is a PDB file, or the Debug-Info is submitted to the file, then the code can be obtained in the development environment (if the debug-info is complete) rarely can be used. The source code cannot be obtained, but you can get "Row numbers and source names", as well as the names / values \u200b\u200bof all constants, local variables, to avoid "fragmentation of functions" as well as get classes with a class filling (almost all structures except the program text) Significantly simplify the understanding of the program's work. For some libraries (DLL), PDB files can be downloaded separately. Hardly self-respecting firm will allow the leakage of the PDB of its worthy product.
• Debug Info, there is a debuginfo-information built-in in EXE. If there is such information, and the corresponding utility (for example, on Borland Delphi is assembled, and it is in stock), you can make a similar one to the previous item. But it is unlikely that a self-respecting company will allow such a "stupid" error (similar to PDB).
• If the file is written on C #, it can be almost completely viewed in codes using DISSHARP (such programs are "plugged" in the import table only MSCORLIB and all). DISSHARP badly disassemble some parts of the program, but its paid version or a paid version of such utilities reveals the code better.
• If the file is written on FohPro, Clipper and other similar byte-code languages \u200b\u200b- it is revealed by special utilities (for example).
• The exescope.exe resourcehacker.exe utility and its-like utilities allow you to watch the header connected to the libraries (you can understand What the program is written) and edit the program resources (resource-form V.T.ch. Delphi, icons, pictures, resource-string tables).
• If you are known than the code created - I think there are special utilities capable of disclosing it (they are paid and lowered).

Again, this is provided that there is no code packer (then you must first apply a depickerker), encrypter / self-modifling code. If it is not broken by the obfuster so do not unravel. The greater the code - the harder it is to understand.

P.S. Personally, my opinion - it is revealed - everything is broken, but it needs to spend a lot of time. Perhaps the year or more (depends on the experience and tools, there is no good tool in free access).

Most likely on your phone already installed by default QR code scanner, you can easily scan the first QR code to scan. Make it very easy. Just follow our instructions.

1. Open the QR code reader on your phone.

2. Keep the device over QR code so that it is well visible on the screen of your smartphone.

If you hold the smartphone correctly over the QR code, then in this case the following will happen:

• The phone automatically scans the code.
• In some applications for scanning code, you must click on the image, and not the button as to create a photo on your smartphone.

3. Press the specified button if required.

Super! Your smartphone reads the code and move on a given link, which does not always happen instantly. On most devices it may take a few seconds.

You will begin to see QR codes everywhere. They are used for training, informing, explanations and for many other things. Find them and scan! QR codes will save you a lot of time and effort.

How to scan QR codes on Android

And now we will tell you how to use the scan application for QR codes on Android.

Briefly:
1. Open Play Market .
2. Search qR code reader .
3. Select QR Code Reader. (via SCAN).
4. Click " Establish.
5. Open the program reading QR-Code.
7. Direct the chamber to the QR code.
8. Click " OK".

Step 1. Open the Play Market on Android. This is an icon in the application or on the main screen.

Step 2. Enter the QR code reader in the search engine.A list of applications for reading QR code will appear.

• This article explains how to use the Reader QR code, but you can choose that the application you enjoy. Just do not forget to read about the application before downloading.
• Steps should be the same for all QR code reading applications.

Step 7.Align the QR code in the Camera frame. A little bit like you do photos, except that you do not need to press any buttons. When the barcode scanner reads the code, a pop-up window will appear with the URL in the code.

Step 8.Click "OK" to open the website. It launches your default web browser and moves to the URL in QR code.

Will not be exaggerated to say that the world mobile devices Right operating systems with open source. Android is still an opens of the project, although, due to the set of proprietary software on Android devices, it does not seem like this.
Do Android have decent open source competitors? To answer this question, let's consider the seven of the most popular OPENSOR mobile operating systems based on Linux. The OS below are listed in random order.

Best Open source Android alternatives

1. Kai Os.

Did you know that Kai OS claims to become the third largest mobile operating system in the world? Most probably not.
Well, it is not surprising. Kaios went to the market not so long ago - in 2017 - but for incomplete two years old became a platform for huge number Mobile phones.
What is the secret here? Unlike other operating systems, KAI OS "sharpened" is not for smartphones, but under Fichthons - classic cell PhonesEquipped with advanced options. The low price in combination with the functionality inherent in the "smart" phones provides Fichchons rather popular.

Being a Firefox OS for the Firefox OS (see below), KAI OS is also based on the Linux kernel.
It is possible to estimate the potential of Kai OS by the fact that Google recently invested $ 22 million into this operating system.

2. Tizen.

The Tizen Opensor Mobile Operating System is supported by the Linux Foundation community, because of which it is often referred to as the official mobile OS Linux. In addition to Linux Foundation, Tizen also supports technhyrants such as Samsung and Intel. The release of the first smartphone with Tizen, Samsung Z was held in January 2015 (although it was originally scheduled for the end of 2013) in the South Asian market. Unfortunately, SAMSUNG Z did not take much success in the Indian market.

Despite the fact that the Tizen operating system is based on the Linux kernel, it has repeated vulnerability in it. Honestly, in the future of this OS is hard to believe. It seems that sooner or later Tizen will outliers.

3. Plasma Mobile

In 2015, the KDE desktop developers created a mobile operating system with open source Plasma Mobile. The application is based on the Kubuntu OS and is essentially mobile version desktop user interface Plasma. In this case, Plasma Mobile is compatible with other operating systems.

Plasma Mobile works on Nexus 5 and Oneplus One. Mobile OS supports KDE Plasma widgets and allows you to download desktop applications on the smartphone.

4. Postmarketos.

pOSTMARKETOS (abbreviated PMOS) is pre-configured and optimized for touch control based on Alpine Linux with its own software packages that can be installed on smartphones.

It is known that Android and iOS cease to release updates for models after several years. At the same time, Linux works without problems on old computers. Purpose PostMarketos - to introduce this experience and on mobile platform, ensuring the 10-year-old life cycle smartphones.

Currently, the project is under development, so take advantage of Postmarketos right now, most likely will not work.

5. Librem

Librem is not even a mobile operating system, but a safe encrypted mobile phone With an open source, which the developers of the Linux-distribution of Pureos plan to be launched in the near future.

The device will get optimized for the touch control version of Pureos, Debian, Ubuntu, SuSe, Fedora and even Arch Linux.

Librem is positioned as a "phone, default security oriented and confidentiality." Smartphone works on free and open software, on the GNU + Linux operating system, and his mission is to "create a utopia of free development in contrast to the fenced gardens of other telephone providers."
We will observe whether the undertaking will be possible.

6. Lineageos.

LineageOS is a Android distribution, in other words, the user firmware. The operating system has replaced a much more successful Android-distribution of CyanogenMod and is its fork.

Released in December 2016, today LineageOS supports 178 models of smartphones, and the number of installations operating systemAccording to the developers, reached 1.7 million.

7. / E / (EELO)

/ E / (EELO EELO) is an Android-Distribution based on LineageOS from the Mandrake Linux developer. The goal of the project is to create an open source mobile operating system that is not attached to Google.
It is assumed that the OS will have its own cloud and email service. Platform / E / should appear in stable version in the near future. The project name is scheduled to change again.

Sailfish OS [Closed source code]

When Nokia refused to develop Mobile OS MeeGo, some employees decided to save the project. It was assumed that Meego would develop the Linux Foundation community within the Tizen project, but the latter received independent development and stopped associated with MeeGo. The continuation of MeeGo is considered Sailfish OS. It was the basis of the MER operating system, which became the MeeGo branch.

The first devices based on Sailfish OS steel Jolla smartphones received hot support Fans of Nokia.
Today, this operating system officially supports more than ten mobile devices.
Although Sailfish OS has a closed sourceIt can be considered as an alternative to Android, iOS and Windows.

Firefox OS [Sales stopped]

It is easy to guess that Firefox OS is Mozilla's OPENSORS, the creator of the Internet browser Mozilla Firefox.. At one time, the announcement of the release of smartphones based on Firefox OS cost only $ 25 made a lot of noise. The target project audience was developing markets like Brazil and India. Unfortunately, it turned out that to repeat the success of the Raspberry Pi alone of the low price tag not enough. As in the case of Tizen, the ZTE devices based on Firefox OS are not gained popularity and at the end of 2015 Mozilla has stopped selling them. However, experiments with Firefox OS continue.

Ubuntu Touch [Supported by Community]

In 2013, the king of desktop operating linux systems I got a mobile version - Ubuntu Touch. Canonical launched a crowdfunding campaign, intending to collect $ 32 million to develop the first Ubuntu - EDGE smartphone. It was possible to collect only 12 million, but also this amount became a record.

After the caught confluence campaign, the Canonical managed to release Ubuntu Phone together with the Spanish manufacturer of BQ mobile devices and Chinese - Meizu.
Subsequently, several other models appeared on Ubuntu Touch. In 2017, Canonical decided to stop the development of their mobile OS, but the UBPORTS community still supports Ubuntu Touch afloat.

What do you think?

Honestly, we strongly doubt that some of the above mobile operating systems will be able to make decent competition android competition. What do you think?
Does the Mobile OS on the Linux database a chance to press Android on the pedestal? Or do they have to be desperate to fight for a little less acceptable share in the market as the desktop OS Linux? Share your opinion in the comments.

Every day, Android applications are becoming more and more. Millions of interesting games and useful programs You can find B. Play Market.. They all have convenient interface and cope with the task. Without them difficult to present the modern world information technologies. This article is focused on people who not only appreciate the functionality and appearance applications, and also interested in their internal device.

If you have ever wondered what is "under the hood" of your favorite application, and you are a little sense in programming - this article is for you. We will tell you how to view Android application source code directly on your gadget. Go!

General

Most of the programs for Android, as much as most of the operating system itself are written in programming language. This means that looking at the source code of Android programs, we most likely see Java code with using Android SDK (which includes Android platform tools). I repeat: To understand the source code of the applications, you need to have basic knowledge of Java and the principles of Android.

How to find out the source code of Android applications?

To start, download the application, the source code of which you are interested. Then go to the Play Market and download the utility called Show Java. It is she who will deal with decompiling. Installed? Excellent, and now we turn to the most interesting - extracting the source code Android program. Run Show Java.

Choose need app From the installed, or find it on the SD card. Now you need to select the decompiler. I usually choose CRF. If problems arise - try jadx.

Upon completion of the process, you will receive a list of packets with sources. Android applications. Of course, this is not a 100% copy of the code, which the developers of this application wrote. But the main logic is preserved, it is not difficult to disassemble. What to do with the source? Anything. See, disassemble, maybe you will be interested in some "features" or features to implement the program functional.

Browser developers took care of the convenience of those who create sites opened in these browsers, namely about webmasters. They added B. standard functions developer tools with which you can easily open and view Site Page source code in browser: HTML, CSS, JavaScript (JS), get different useful data on the site structure, conduct its technical analysis. In general, see a lot of useful.

Of course, these tools use not only the creators of sites for work, but also simple users to which the source code allows you to view various useful data.

From this thing you will learn how in the browser to view the source code of the site page (how to open HTML, CSS, JavaScript site code).

How to open the source code of the page in the browser

Open the source code of the web page in the browser in two ways:

1. With hot keys;
2. Open from the context menu.

Ctrl + U. - Combination of hot keys to view the source code of the entire page of the site in a separate new window. Standard for all browsers: Google Chrome., Opera, Mozilla Firefox, Yandex Browser, IE.

Also in developer tools can be logged in as follows:

In order to quickly find the desired code, word or text on the page, you can use the standard for all browsers a combination of hot search keys: Ctrl + G.

Video instruction:

View code code | Explore element | Inset element

If suddenly you need to view not all source code, but to display only a separate part of it, some kind of plot on the page, the previous tool will not fit. For this, the developer's tools have another feature that will be discussed below.

How to view an item code on page:

In addition, you can use keyboard shortcuts for quick access To inspect the element.

Hot keys (buttons):

Google Chrome: Ctrl + Shift + I and Ctrl + SHIFT + C

Opera: Ctrl + Shift + I and Ctrl + SHIFT + C

Mozilla Firefox: Ctrl + Shift + I and Ctrl + SHIFT + C

Yandex Browser: Ctrl + Shift + I and Ctrl + SHIFT + C

After the actions done, the source code of the web page will open in the same browser window:

All HTML code will be in the left large column. BUT CSS styles - in the right.

Advantage this methodOf course, it is also the fact that the user has the ability to change the source code, edit styles. That is, you can edit styles on the site and see how it will look with those or other styles, without having to immediately make changes to the files that are on hosting servers. To change or add program code, It is necessary to make a double click on the desired fragment or plot. Of course, the correction of the code in the browser is not listed on hosting servers. Therefore, in the future, in any case, you have to copy this code and register into files.

In this video instruction, it is described in detail and shown in detail how to work with the developer tools:

That's just just online, right in the browser, you can see the source code of the site page, get the basic data on HTML and CSS code, change and copy them, without having to download the files of this site to the computer.

By the way, inexperienced Internet users who changed the page code and waiting, which will continue, is waiting for disappointment. After all, after updating the page, all changes will disappear on it. This is not enough to hack the site 🙂

How to view the source code on the phone android

I would also like to note that the developer tools are available not only in the desktop version of the browsers, that is, on computers and laptops. On the phones and tablets (Android, iOS) you can also view the source code.

To do this, add the View-Source inspected page to the URL:

For example:

view-Source: https: // Site / Turbo-Rezhim-Opera /
