Launcher is a system bootloader program. They come in different types - some control the launch of the operating system, others change its appearance. Let us describe the frequently occurring problems with them in Android and Windows operating systems. Let's start with Android devices: launcher 3 what is this application and how to restore it to normal operation.
The Android OS is developing and improving. Smartphones and tablets under its control are used all over the world. It's a shame when a demanded mobile device crashes - applications stop starting or a phone number is not dialed.
What is a launcher on Android is a shell program that allows you to change icons, desktop design, menus, widgets, add new functions. Launchers are placed on top of the OS, transforming it externally, while all system procedures remain the same. Some manufacturers - for example, ASUS and many Chinese companies - specifically design a proprietary interface for their devices, making them stand out from many others.
Now you know what a launcher 3 shell on Android is. As with any program, bugs and freezes sometimes occur when the launcher is running. We will tell you how to deal with them.
Clearing the cache
If you see a message on the device screen: "An error has occurred in the launcher application", click OK and restart the device. On not the most powerful smartphones, simplify the interface - reduce the number of desktops and icons, disable rarely used widgets.
If the application error persists, data:
- In the menu open Settings - Applications - All.
- Find launcher 3 or a similar name in the list of programs.
- Open the "Properties" menu of the launcher, click "Stop".
- Select the items to clear data and cache.
- Power off and on completely.
- Launch launcher3 again.
Removing programs
What if, after clearing the cache, launcher 3 does not want to work correctly? Remember if you installed new applications before the problem occurred. They can conflict with the launcher, causing it to malfunction. In this case, try uninstalling the latest installed programs.
If you repeat the errors, delete the launcher itself. To do this, open the "Settings" menu item, go to the list of applications, find the program in it. Select its properties, click "Delete".
Installing a different shell
Sometimes installing a new shell helps to fix the problem. There are many launchers on the Google Play store, the most popular are Nova, GO EX, Buzz, Apex, Solo. They differ in the number of built-in themes and additional features. Download a verified application and select it as the default bootloader - this will help remove the consequences of the previous one.
Factory reset
If even uninstalling the launcher did not fix the normal operation of the device, try the full one. This will delete all data and programs from the internal memory, your smartphone or tablet will become as clean as after purchase - only basic programs (calls, messages, calendar, etc.) will be saved in the system.
Transfer all important information - phone book, photos and videos to your computer in advance. In the "Settings" menu, find the item "Restore and reset", select "Factory data reset".
On some versions of Android, you need to call the system menu to access the function. Most often, for this you need to turn off the device, then hold down and hold the Power and Volume Down buttons. The key combination is different for some manufacturers:
- Samsung: Power, Home, Volume Up.
- LG: Power, Home, Volume Down. When the LG icon appears, press Power, hold the remaining 2 until Recovery appears.
- HTC: Hold Volume Down and press Power once.
- Huawei: Power and both volume buttons.
- Sony Ericsson: Power, Volume Down and Camera Key.
In the submenu that appears, go to Factory reset.
Device firmware
What if after all the operations the launcher 3 error continues to appear? The last step is to completely change the firmware. This action is not easy - so look on the Internet for instructions specifically for your model (you will definitely need Root rights) or take your mobile device to a qualified service.
On Windows
On Windows, you may encounter a launcher too. If you see a delayed launcher application in the system startup, do not panic, this is not a virus. This utility controls the launch of programs when the computer is turned on, setting certain delays for loading. This order allows you to start Windows faster by distributing system resources - first one application is launched in memory, then another.
You can always disable this launcher by unchecking the corresponding checkbox from it in the startup window. There you will also see its location - the path to the exe file. But do not just delete the exe using the link, this will lead to system errors - use the built-in "Uninstall Programs" function.
Perhaps this is the most banal, but quite effective way. At times, the operating system crashes, and when turned on, not all files are downloaded in the correct order. Due to such troubles, the launcher application may not open correctly and give an error. To get started, don't panic, just try restarting your device.
Clear unnecessary data
At the bottom of the inscription "An error has occurred in the launcher application" there is always an "OK" button. You can click on it. After that, you need to go to the menu and clear the bootloader cache. How to do it?
To do this, you need to go to the gadget settings, from where you go directly to the launcher application. It has "Erase Data" and "Stop" buttons. Then click on the exit or Home button. This will restart the launcher. So the program will start over and, possibly, stop giving an error.
Try another launcher
When an error occurred in the com android launcher, you can try to get to the "Market", from where to install another program. There are actually a lot of options:
- Nova Launcher;
- ZenUI Launcher;
- Evie Launcher;
- CM Launcher;
- Hola Launcher.
This is not the entire list that can be found for devices on the Android platform. Each of them is easy to customize to suit your needs and requirements. They have different variations of labels, visualizations, and so on.
Software conflict
If the problem appeared after installing an application, even if it was taken from the Market, it may make sense to try to remove it. Why could this situation have happened? There are several reasons, but the main one is the halt in the development of one of the applications. This happens when developers stop a project, and their applications remain in the public domain.
Factory settings
If the previous methods cannot be used due to the fact that the text "An error occurred in the launcher application" on the tablet or smartphone does not allow you to do anything, or for any other reason, you can try to reset all settings to factory defaults. This can be done in two ways - through settings or recovery.
Even a child can master the first method. To implement it, you need to enter the menu and the "Recovery" section. There is a button we need to reset all settings to the factory settings. Everything will have to be installed and configured again. Be aware that everything that was saved in the device's memory will also be deleted, including photos, SMS messages and numbers.
Recovery
This method is suitable for more advanced users. In each device, the entrance to the recovery takes place in a different way. But in most cases, this is pressing several keys at the same time, for example, the power button and the volume rocker. In order to find out exactly how your gadget goes into this mode, just type the name of the model of your gadget into the Internet and add the word "recovery". Next, the search engine will give you the most suitable options.
Once in the desired mode, you need to select the wipe data \ factory setting item with the volume buttons and confirm your choice with the power key. All gadget settings will be reset to factory settings.
Flashing
If the previous method did not help you or only gave you a short-term relief from the annoying inscription "An error has occurred in the launcher application", android can be reflashed. In order for everything to go well, you need to calm down and concentrate as much as possible. Information on how to properly flash your particular gadget can be found on numerous large forums. Try to choose the most discussed firmware with a high rating and follow the instructions clearly. If you have little experience, it is recommended not to experiment too much. When an error occurs in the launcher, it may be necessary to establish Root rights, and this is not an easy task.
When self-repairing, you need to understand that there is a risk of completely losing the device by making the wrong step. For those who do not like to take risks, there are always many qualified specialists who have undergone special training and can solve the problem as competently as possible.
Preventing such a situation
The text "An error has occurred in the launcher application" can be very scary for the user of the gadget. To avoid such an incident, keep an eye on the number of icons on your desktop. Try not to load the desktop all at once. Monitor all new installations. Keep order even on this desktop.
The standard interface gets boring over time. Therefore, users are looking for an alternative to stock skins and turn to the services of third-party launchers. But behind a beautiful interface, there is often unoptimized code that leads to errors. So let's take a look at what Launcher 3 is and how to fix application errors.
About the program
It is a graphical system shell that includes the desktop, menus, widgets, icons, lock screen, etc. Each of these elements can be fine-tuned "for yourself".
Some Chinese-made smartphones use Launcher 3 as standard, so removing it or force stopping it will cause more serious problems. 
Errors in Launcher 3 occur due to failures in the process of exchanging packet data, which, although they are restored after a while, are pretty annoying by the frequent appearance on the smartphone screen. Those. the problem has a more cosmetic effect than predicting a major failure in the device's operating system.
How do I fix the application error?
After digging around on mobile forums, I found many ways to work around the ill-fated error. Some users solved the problem drastically: resetting the device to factory settings or performing a full flashing of the smartphone. I do not agree with the opinion of the members of the forum, tk. the above methods should only be used as a last resort.
And I will present an easy and quick way that does not entail deleting user files and resetting the settings:
- Disconnect your phone and remove the battery.
- After a minute, assemble the device and turn it on.
- Go to "Settings" - "Applications" - "All".
- Find Launcher 3 and tap on it.
- Stop the application and click on the "Storage" item.
- In the window that opens, click on "Delete data" and "Clear cache".
If you installed the application yourself and want to uninstall it, then after completing the fourth point, click the "Remove" button and confirm the operation.
After these steps, the error will no longer be displayed on the smartphone screen, but this does not guarantee that it will not appear in the future. Therefore, it is recommended to install another shell, for example
Occasionally, Android crashes that backfire on the user. These include the constant appearance of messages "An error has occurred in the application." Today we want to tell you why this happens and how to deal with it.
In fact, the appearance of errors can have not only software reasons, but also hardware ones - for example, the failure of the internal memory of the device. However, for the most part, the cause of the problem is still the software part.
Before proceeding with the methods described below, check the version of the problematic applications: they may have been recently updated, and due to a programmer's flaw, an error appeared that causes the message to appear. If, on the contrary, the version of this or that program installed in the device is rather old, then try updating it.
If the failure appeared spontaneously, try restarting the device: perhaps this is an isolated case that will be fixed by clearing the RAM upon restart. If the version of the program is newer, the problem appeared suddenly, and restarting does not help, then use the methods described below.
Method 1: Clearing data and application cache
Sometimes the cause of the error can be a failure in the service files of the programs: the cache, data and the correspondence between them. In such cases, you should try to reset the application to the form it has just installed by clearing its files.
- Go to "Settings".
- Scroll through the options and find "Applications"(otherwise "Application Manager" or "Application Manager").
- Once you get to the list of applications, switch to the tab "Everything".
Find the program that is causing the crash in the list and tap on it to enter the properties window.
- An application running in the background should be stopped by clicking on the corresponding button. After stopping, press first "Clear cache", after - "Clear data".
- If the error appears in several applications, go back to the list of installed ones, find the rest, and repeat the manipulations from steps 3-4 for each of them.
- After clearing data for all problematic apps, restart your device. The error will most likely go away.
If error messages appear constantly, and system errors are present, refer to the next method.
Method 2: Factory reset
If the messages "There was an error in the application" are related to the firmware (dialers, SMS applications or even "Settings"), most likely you have encountered a problem in the system that cannot be fixed by clearing the data and cache. The hard reset procedure is the ultimate solution to many software problems, and this one is no exception. Of course, in this case, you will lose all your information on the internal storage, so we recommend copying all important files to a memory card or computer.
If none of the options helped, you are most likely experiencing a hardware problem. You won't be able to fix it yourself, so contact the service center.
Conclusion
Summing up, we note that the stability and reliability of Android is growing from version to version: the newest versions of the OS from Google are less prone to problems than the old ones, albeit still relevant.
