The Android cache is the data that applications create during their execution. They are necessary for faster work of these programs. For example, image viewers create thumbnails of images in order to immediately display them in the future, rather than load the processor each time in order to create miniature copies. In the case of browsers, the cache is needed so that in order to display the site that was once previously opened in the application, do not load data that usually does not change (for example, images).
Why do I need to clear cache android?
Despite the fact that the cache stores useful data that allows applications that have created them to work faster and consume less energy, sometimes they can deliver one significant disadvantage to the user – resulting in a lack of space on the drive. This is understandable, because the corresponding files with time may appear very much, and some of them will have an impressive size.
For example: if there are 25 applications installed on the device, which are regularly used, then a month later the cache is likely to grow to 7 gigabytes, and perhaps more. If the device has a drive of only 32 gigabytes, then the presence of such a large amount of relevant data will become a problem. As a result, you need to clear the Android cache.
What happens when you clear the cache on your phone?
In general – cleaning the cache in the android is completely safe, with one exception – you can lose not saved information in running applications. Therefore, before clearing the cache, you need to save all the important information for you in already running applications.
The cache in the Android operating system is divided into three types:
- system cache;
- application cache.
Dalvik-Cache is data created by the Dalvik virtual machine. It stores the optimized files of applications that are needed for faster execution of programs. Those, in turn, are on a special section that is invisible to the user who does not use special applications.
The system cache stores program data that is embedded in Android. In the process, the system creates files into which it records information that can be reused.
The application cache is a repository of data that was created by third-party applications (for example, downloaded from the Play Market). It may contain: thumbnails of images, images uploaded in the browser, game files, etc.
The main ways to clear the cache in Android
The system and application cache can be cleared in two ways: through the built-in utility and using one of the special programs that are available in the Play Market.
Deleting the cache with the built-in utility is a safer way to get rid of the relevant data. The system is guaranteed not to harm the files that are needed for the programs and the system, as well as user information. When working with third-party applications, in turn, should be more careful.
How to clear the cache on Android
Now let’s go directly to the question of how to clear the cache on the Android phone.
To delete the relevant data without using third-party software you will need:
- go to “Settings” (through the menu or curtain);
- find the category “Device” and select “Memory”;
- click on the item “Cache data”;
- in the pop-up dialog box, click on “OK”.
After a few seconds (the exact time depends on the size of the accumulated files), the mentioned window will disappear, and the value “Available” will increase by a number equal to the number of megabytes/gigabyte, which was previously indicated in “Cache data”.
How to clear the cache of only one application
Now how to clear the cache on Android for only one specific application. To do this you will need to perform the following series of actions:
- go to “Settings”;
- select “Memory”;
- Tap on “Application data …”;
- go to the tab “All”;
- find and select the application whose cache you want to clear;
- on the displayed screen, click on “Clear cache”;
- confirm the action by clicking on “OK”.
After a few seconds, the cache data of this application will be deleted.
After deleting the application data, you may need to log in again (for example, in the case of social networking clients). Therefore, before cleaning, make sure that you have access details to the account to which you go to connect through the application.
Android application for cleaning the cache
One of the most popular applications that allow you to clear the cache on Android is Clean Master. This program can be downloaded for free from the Play Market. Using it is easy:
- first you need to download and install it;
- starting, you will need to click on the “JUNK FILES”;
- on the screen that appears, select the application whose cache you want to clear;
- click on “CLEAN JUNK”
This application can be configured to clean the cache at a specific time.
There are also other programs for cleaning the cache, for example, App Cache Cleaner, Power Clean, CCleaner and others.
App Cache Cleaner – an application that, in addition to clearing the cache in manual and automatic mode (at a specified interval), can also transfer certain application data to a memory card. Suitable for those who have little space on the internal drive, but installed MicroSD.
Power Clean is an application that has many features. With it, you can not only clear the cache, but also delete old files that have not been used for a long time, speed up the system, cool the processor, etc.
CCleaner is a mobile version of the well-known application for personal computers on Windows. It has functionality similar to Power Cleaner.
