You open the app, but it immediately closes. You open it again, it does the same. There is clearly a problem here, but clearing app data and cache can be a fairly simple fix.
Like any other operating system, Android stores certain application data that stores your settings, logins, and so on. That's why you can just fire up Facebook or Instagram and not have to log in every time. But sometimes this data can become corrupted and cause problems.
There are two main types of files that can be cleared from apps: cache and data. Cache files are just temporarily saved files downloaded by an application. For example, when playing music, the app can preload songs during playback to avoid any crashes. These files are then saved as cache files. After clearing the cache, the app will just need to reload any files it has saved for temporary use.
Data is important information stored in the application. They contain login information, application settings, and so on. When you clear app data, it's like uninstalling and reinstalling an app. Cleans up everything stored in apps, making it work like new. This is sort of a "worst case" solution - if clearing the cache doesn't help, then clearing the data should do the trick.
Clear app cache and data
If you have a problem with an app, you should start by clearing your cache. This may not be the cause of your problem, but it is a simple and safe first step.
To do this, first open the "Settings" menu and then go to the "Apps & notifications" section.
If your phone is running Android Oreo or later, you'll need to tap the App Details button to view the full list. Otherwise, just find the app you're having problems with.
Once you find the application, the first thing you need to do is to kill all running instances. Click the "Stop" button, and then confirm this action in the pop-up window.
When the application is closed, click on the "Storage" item.
In the "Storage" menu, click the "Clear Cache" button.
Try running the application again. If the problem persists, you can repeat the above steps, but instead click the "Manage Location" button and then "Delete All Data". Just be aware that you will lose your data associated with this app.
If next to the "Clear cache" button is the "Erase data" button instead of "Manage space", then click on it.
The next time you launch the app, you'll need to set it up as if it was just installed, but hopefully this fixes the problems you're experiencing.
If none of these steps fix the problem, the problem may not be on your side. This could be a buggy update released by the app's developer, at which point it's best to file a bug report with the developer and hope it gets fixed.
What is a cache? What is it for? How to clean it and why is it necessary? Such questions are often asked by novice users of smartphones and tablets running the Android operating system. Let's take a look at these questions.
What is cache in android?
The cache is a special place in the internal memory of the device, which contains temporary files of games and applications. These can be audio and video files, application data, images, scripts, etc.
The cache in Android is needed to reduce data access time and, accordingly, increase the speed of applications, as well as to reduce the load on RAM. The caching algorithm in Android OS works in such a way that the most frequently requested data is stored in cache memory, from where it can be retrieved faster the next time it is accessed. The main purpose of the cache is to speed up the system.
To make the caching algorithm clear, let's give a simple example at the household level. Imagine a library where the librarian lends books to readers. Books are stored in the hall, from where the employee takes out the requested publications. Some books are in high demand, and some are not in demand. To cut down on his work, the librarian begins to store popular books next to him, so as not to go to the hall once again and speed up customer service. In this example, the library is the internal memory of the device, the books are the data, the reader is the application requesting data to be processed, the librarian is the memory controller serving the requests, and the rack of popular books next to the librarian is the cache.
Why do you need to clear the cache?
Based on the above, we can see that caching applications is a useful process, however, the cache sometimes needs to be cleared. The main reasons for this action are the growth of memory for data and the incorrect operation of the application. With active and prolonged use of applications, their cache grows, and if the device has a shortage of internal memory, then cleaning to some extent will help resolve this issue.
Clearing the data of a crashing app can help get rid of its incorrect behavior. After all, it also happens that erroneous data is stored in the cache, which leads to a failure in the application. You need to understand that clearing the cache is not uninstalling the program, but only deleting temporary files.
The cache can be cleaned in two ways: using the regular application manager and special programs, the so-called cleaners.
Clearing with the application manager is somewhat inconvenient and more suitable to clear the data of a specific application.
Cleaning with special applications is the fastest and most convenient way. The official store has a large number of applications for cleaning up junk files in Android. One of the required functions in such programs is clearing the cache. The most popular among them are Clean Master and CCleaner.

Cache(cache) is a part of RAM (or disk) memory for storing previously used data, which speeds up the process of repeatedly accessing them. For example, browsers use a cache to store copies of frequently visited sites. However, an uncontrolled cache tends to grow to unprecedented sizes, take up memory and slow down the computer. And this means that the cache is needed.

Cache- a set of pictures, video files, snapshots of pages and other materials from the sites you visit. Each of your visits to a new site is accompanied by a record of such data. When you re-view, loading Internet resources is faster, since many of the displayed materials are not taken from the Internet, but from the cache. But a large amount of stored information can slow things down. For this reason, the cache is recommended to be cleared periodically. A few simple steps will help you do this.

Now in the Google Play Store you can find a bunch of applications that offer you to take care of other programs and, among other things, clear the cache of third-party applications. But in fact, in Android, this does not need to be done so often. In most cases, it’s not worth doing such things at all, since this can only disrupt the operation of installed applications or lead to re-consumption of traffic, etc. But sometimes there are times when clearing the cache is necessary.
What is a cache and why is it needed?
When you install applications, most of them begin to collect some kind of their own local cache, where the data that the program needs all the time to work correctly and quickly is dumped.
The simplest example with maps. Have you noticed, for example, when you download Yandex.Maps on Android for the first time, the application starts downloading a map from the Internet? If you run the program again, for example, in a day, then the same area will be opened and displayed instantly. Because some area of the map has already been downloaded to the internal memory of the phone, the program cached it, and now it gets the files from the cache, and does not download them again.
Or, for example, when you communicate with Telegram, and someone sends you a photo, it is also cached in the Telegram service directory, so that when you access it again, open it instantly.
The Instagram client and other applications installed on your device behave similarly.
When do you need to clear the cache on Android?
- If the application behaves unstable, crashes, crashes or slows down a lot, but before everything was fine.
- If free memory on the device has run out, and space is now vital.
Of course, it is better not to bring it up to the second case. If you need to save data somewhere, then you should get a more capacious memory card or immediately buy a smartphone with a large number of gigabytes available to the user. You can also transfer some of the data, for example, photos and music, to the clouds, and store only the most necessary things on your smartphone, which should always be available even offline.
Moreover, cleaning the cache to free up memory usually does not win much. Even if you resort to the help of the most corrosive applications from Google Play. A couple of hundred megabytes, it is unlikely that you will succeed much more.
In the first case, if an application that previously worked correctly suddenly began to behave inappropriately, it is worth clearing its cache. This can save you from reinstalling the program by losing settings or completely resetting your smartphone to factory settings. Everything is easily done by the means of the system, you don’t even need it.
How to clear the cache on Android?
This is done simply. In the global settings of Android, you need to go to the list of all installed applications. Next, scroll the list to the desired one and use the tap to go to the information about the program. Then we look for the "Clear cache" button there.

No matter how much memory an ultra-modern tablet has, sooner or later it becomes clogged with all sorts of unnecessary files. Therefore, before each owner of such a gadget, a completely logical and logical question arises about whether the browser is on Android? After reading this article, you will learn how to do this in several different ways.
Why is there a need to delete files?
Before you start to figure out how to "Android" you need to try to understand what is meant by this term and why there is such a need. The system cache is nothing more than a set of videos, images, text and other auxiliary files that are responsible for the most correct display of Internet browser pages.
Surely, many of those who are interested in how to clear the cache on Android have repeatedly paid attention to the fact that it takes some time to load a web page. Sometimes this process is fast, and sometimes you have to wait quite a long time. The more you use the Internet, the more files are stored in the cache of your device. On the one hand, this saves Internet traffic. On the other hand, the question arises of the advisability of storing a large number of unnecessary files, many of which may never be used.
The same is true for games and apps. Any action or achievement is stored in the cache, and it is completely incomprehensible why this data is accumulated if the user wants to get rid of the annoying game or application.
Cleaning with built-in tools
Before you clear the cache on Android, you should figure out what we win as a result of such actions. It must be said right away that such manipulations allow us to solve several important problems at once. Clearing free space in memory contributes to a significant acceleration of the entire system.
In any modern device running on the Android operating system, there is a special function that allows you to get rid of unnecessary files. To use it, you should open the gadget settings and, by going to the “Memory” section, go to the “Cached data” tab. As a result of these actions, a proposal will appear on the screen to free up memory from unnecessary files. After clicking “Ok”, the cleaning will be performed. However, it should be understood that repeating this algorithm too often can harm the system.
How to perform a full cleaning of the device?
For those who do not know how to clear the cache on Android, it will probably be interesting that this can be done by resetting to factory settings. This will completely clean the device, erasing everything that was recorded from it after purchase. To get rid of all unnecessary files, you can go to the gadget settings and find the “Privacy” tab there. After that, the user just needs to press the "Reset settings" button and reboot the device.
Getting rid of junk files using third-party programs
Those who are interested in how to clear the cache on a tablet ("Android" is installed quite often on these devices) will be surprised to understand that this can be done using special software. The work of all "cleaners" is based on the same principle. Therefore, the user needs to open the appropriate program and, after running the memory analysis, wait for a report on the files found that can be disposed of. To start deleting data, you need to activate the function
One of the main advantages of using such utilities is that they immediately show how much memory will be freed as a result of getting rid of cached files.
