    Default How to prevent Android Applications from crashing or freezing

    A lot of applications crash or freeze and it does become annoying, sometimes the only way to start the application is to close it and then start it again, once the phone allows you to do so, because if it freezes then typically you are stuck with a application screen which you can not do anything about, unless you switch the phone off.

    The reasons why applications tend to crash because of certain permission which may not have been given at the time of installation, which can be resolved by third party applications. Not everyone like using third party applications, so that is another door closed to resolving problem.
    This is not the only reason for applications freezing and it can also occur because of storage space in your mobile phone. In this case you would need to clean up application caches and deleted and uninstall unused applications which would make a big difference. To make life easier downloading the application Clean Master, which would clean application caches on a regular basis.

    The last point which may affect the applications freezing is the system not being updated. In order to update your system you need to go into the settings option in your phone, then select the about phone option and then system update. You should do this at least once every month.

    Good thread. Would reinstalling the application also prevent any problems occuring like crashing or freezing?

    It may resolve the crashing problem if the fault is in the application, but if its due to something in regards with the phone then the above mentioned suggestions need to be applied.

    You can set check for system updates automatically once connected to internet.

    I would like to add that there are two options for system check either with a WiFi connection or with data pack, so it is vital you make the correct choice otherwise our data would be used up if you have a lot of applications and they would be updated on a regular basis.

    Phones generally freeze when sometimes more than one applications are running simultaneously, and this depends on the phone and its features on ow well it can do this. With the low end phones you would expect a phone to freeze if two applications were running but the high end phones have this capability.

    It also depends on the actuall application as well, sometimes applications have problems in them as well, so it is vital that you download and use a verfied application.

    also depends on how much free space is available in the external memory, if the application is set to SD card

    OK. OK. Android Apps freezing is such a big issue for discussion, that a thread wouldn't be sufficient for it.

    In the android OS, an app uses two main layers of execution, one is the main thread, and the other layer contains all other threads which execute through the main layer. The main thread/layer is the one which performs most of the CPU IO, kinda like the main controller. When an application is running, and some process uses the main thread for too long, you will see and ANR (Application Not Responding) message. If the Main thread has to wait for some process for too long, you might see an ANR. If there is malware on your device and it writes to the memory constantly, the main thread will have to wait for longer periods of time to get CPU or memory(RAM) access. This will throw an ANR. You have an app that needs to show you an advt. before it allows you to access the main menu, and if your internet connection is slow, or not available, it may throw an ANR.
    And the list goes on like that...
    Now-a-days, Android OS has been polished so far that such fickle ANRs are not shown altogether, and if a program causes longer writes to the main thread, it is terminated automatically, and we view this as a crash.

    Who said that only Androids have ANRs? In iOS, ANRs are hidden from the user and the application quits (actually crashes), but their app store uploads are screened more stringently than any other, and thus these crashes are seldom seen, but they do exist.

    I have a lot of spare space in my phone, and yet my phone is still slow at times, can it be that some applications take up some extra usage?

    It is the application itself which is causing issues then and not the problem in the phone. I downloaded Candy Crush and when I used it on my phone within 10 minutes my phone got so hot and became so slow. I have the clean master application and that used to send alerts every 4 hours because it used up a lot of RAM.

    Games are a big problem and cause for phones getting hot and taking up a lot of space. Ever since I have uninstalled games from my phone, number one my battery lasts longer, I have more space in phone and the phone does not get hot as much. It is best to play games on a tablet.

    I think you can easily download an anti virus for your mobile phone as well. Clean master has a virus check feature as well.

    First of all it depends on your device. You have to be sure that your device can handle the application above the minimum required settings. There are applications which can run on minimum required settings and will cause crashes most of the time.
    Second, check for applications running in the background. Most applications installed run in the background even if you don't use them. Either remove some applications or just deactivate the background applications running.
    Third, your device might have malware or viruses. I really don't use anti virus software so I just stick to the usual websites just to be sure. If I really need to look into shady websites I do it on a different device which I can safely format or don't connect to my network.
    Lastly, you can use a booster application (provided that your phone is well above the minimum required settings). Try using one like Dr. Booster for running your app or Dr. Safety for checking malware.

    If all else fails, maybe the application is really bugged and crashes all the time because of faulty programming. Well it happens especially for games.

    I hope this helps

    I don't think you can remove the crashing from the phone, it will happen. But try to quit the background apps so it won't use too much of your RAM. My phone is old so a lot of apps are crashing (sometimes even the system ) and I don't mind it. If it happens a lot you will get used to it.

    There is not much you cando to prevent them rom crashing. Most of the times it's related to bugs in the app itself and all you can do is wait for updates to fix those bugs, other times it's your own device that is not very compatible and the app will never work properly. There are also a few times that the app takes longer to load or to display a menu and tha majority of people is impatient and start touching the screen to see if something happens, and the device will shut down the app because it is being overflooded with actions (the multiple touches from your fingers). All I can say is: make sure the app is compatible with your device, and wait for the app to load and don't start touching the screen randomly.
