File Extension APK

What is ?

An APK (Android Application Package) or file with the .apk extension contains an application for the Android operating system.

It is an acronym for Android Application Package fFormat. It is very similar to the executable we have in Windows (.exe or .msi) from which we install software.

This format is basically a compression format similar to the ZIP. Inside it contains all the necessary data for an Android application to work.

In summary, this format contains, the installer for applications or games. With these  you can get applications outside of Google Play.

These allow us to install applications outside of Google Play. Thanks to these  we can get filtered apps. Also, versions of applications different from those offered by Google Play, friend apps or opensource applications that are not published in the Google Play Store.

So it means having things that only a few have. New and interesting Apps that would not otherwise be accessible.

Download

To install these  on our smartphone or tablet, we first have to download it from the internet.

There are several sources to get it with applications like APKMirror, for example where you can get some not available in Google Play.

But beware when installing paid applications. Because they may contain viruses, malware or be malicious applications.

 

How to install

In order to install this format we must first disable a security option. Android is configured by default so that only Google Play applications are installed.

To activate the installation of applications with unknown origins we must enter Settings> Security and mark the option of Unknown origins. We will have a warning with the risks and we will have to accept to activate the option.

Now we can search it on our smartphone or if we have downloaded it from the download notification. Now you just have to select it and the application installer will launch automatically.

Click on install and it will take a while to install depending on the size of the application.

A.P.K. is the format in which apps and Android games are distributed. When we download an Android application from any website different from the Play Store. Either on the device itself or if we download them (or compile ourselves) on our computer.

This type of files also has a series of information included that gives us clues about the operation of the application or game. Information that, if we want to consult it from Windows before passing it to the phone, we can easily do so using a free tool called APK-info.

 

 

APKInfo

It is a free application for Windows designed to allow us to see all the information included in any .APK of Android directly from Windows. This can be done without having to copy it to our device or use an Android emulator to see all this information.

The information that allows us to consult this program of the Android files is the name of the app or the game.

Also, the version and compilation, the name of the app package. Moreover, the minimum and objective versions of the SDK, size and resolution of the screens for which it is optimized, the permissions that the application requires to work and if it has other additional features.

In addition, this application also allows us to automatically rename including the name and the version of the app or game. It is very useful to have it always at hand if we save it on our computer.

How it works

This application is completely free and open source. To download it, we simply access its official GitHub repository and download the latest version from there. The application does not need installation. So once downloaded, simply unzip it on the desktop and execute it.

When executing the application we can see a window of the Windows Explorer from which we must look for the route where we have saved the ones that we want to analyze.

We look for it in our computer and, when we select it, we will be able to see a new window, like the following one, where we will see all this information related to it.

This application does not offer us much more than what we already see, but it perfectly fulfills its mission: to allow us to consult the information of the files.

If we want, next to the program's own filenames we can find two Windows registry type that will allow us to add this application to the contextual menu, being able to analyze any one more quickly by simply clicking with the right button on it.

We remind you that, for security, it is always advisable to download the applications from the Play Store itself, since one of the main sources of malware distribution for Android are downloads from third-party stores that are not trusted.

The Play Store, although on multiple occasions it has been compromised, at least it usually controls a little the applications that are published, being more difficult to infect from this store than from, for example, Aptoide or webs of download of apks.

 

 

How to download from playstore

Normally Android applications can be downloaded to our tablets and smartphones from the corresponding application of Google (Play Store), but it may happen that for one reason or another we want to ask the installer.

For example, to have a backup of all our applications to avoid having to download the application again in case of formatting the mobile.

 

In order to download we will need:

  • Have Chrome (or Chromium) browser installed.
  • Install a plugin in the browser.
  • Get the DeviceID of our android.

The plugin  can be downloaded from the author's website. We will download it with format .crx which we must drag on the window of extensions of the browser so that it is installed.

 

Once installed it will appear in the list of browser formats.

 

We must click on "configuration" to access the configuration. Here we must enter our email address, our password and the ID of our device.

To obtain the ID of our device we must install the DeviceID application available in the Play Store and write it in the plugin.

Once the data has been entered, we will click on Login to activate it with our configuration. After this, we will have it running.

To test it we access the Play Store on any application and we should see an icon in the address bar to download it. We click on it and the download will begin.

The developer has disabled it for payment applications. It is not aimed at piracy actions. It also warns us to use it at our own risk since it violates the term of license 3.3 and you never know how Google can respond.

We must also think that we are providing some sensitive data to an application of unknown origin. Although the developer tells us that it does not store any data, we do not have access to the source code to see that it is true. You have to be careful when using this type of applications.

Surely more than once you have encountered the problem that your new smartphone or tablet seems not compatible with Google Play and you have been unable to install from there the application that interested you or that you had recommended.

Obviously we are not going to attribute a merit that does not correspond to us, so we are obliged to praise the work done by the developers of APKDownloader. Which will allow us to download directly on our computer to install them on our device or store them to be able to install them in the future without having to access Google Play.

 

How to download from Google Play directly

 

Simple operation to get free applications from Google Play

The operation of APKDownloader is really simple. Although we must emphasize that it only works with those applications that are free.

In order to get the .apk of the app that we want to get, we will only have to write in the corresponding window the name of the application package - which in the URL of Google Play is what we will find behind? Id = - or the complete link to the page of said app in the online store of the American giant.

After doing so, we just have to click on "Generate download link" . Then on "Click here to download ..." to obtain our precious booty. Now it's time to remind you once again how to quickly install the applications on your smartphone or tablet, starting only from it.

Once we have downloaded it to our computer, all we have to do is send it by email, as an attachment, to the address that we have configured on our device.

Once received on the tablet or mobile phone, we will only have to execute that app that we have previously attached and start the installation normally.

You can also Download your favorite applications with this program.
