Basic Troubleshooting for Android Games
1. Restart your device
If you are having trouble with a game on your Android device, please first try simply turning your device off and on again. It's a cliche for a reason--it often does the trick!
2. Clear the app data and cache
You're often advised to clear your browser's cache, but on Android devices, you have the same ability with apps, and it's helpful in just the same ways. Imagine a robot walking along a track, and it comes to an obstruction of some sort. The robot doesn't have a way to change course and walk around; it's just going to keep bumping into the object. If you clear the cache, you remove the blocker, and the robot can move forward again.
Open your device's Settings menu, and look for the app in question on the list of installed apps. Tap its name in the list to open the expanded menu. There will be buttons labelled Clear Data and Clear Cache. If you try Clear Cache, and it doesn't work, you can then try Clear Data. If you try Clear Data first, it will clear the cache at the same time!
3. Force-quit the app
When you've launched an app, it remains active in the background unless you manually close it. This is great, because it lets the app load faster the next time you want to use it, but it can also cause problems. Sometimes a program simply needs to be allowed to sleep a moment and wake back up.
Open your device's Settings menu, and look for the app in question on the list of installed apps. Tap its name in the list to open the expanded menu. Tap the Force Stop button to quit the app completely.
4. Force-quit other apps
As we established above, the apps you launch will remain active in the background for faster loading. But how many apps have you launched? How many programs are still taking up processing power while you're not even using them? If you're going on a hike, and you've packed your backpack with provisions, it will weigh you down some, but you need everything in there. But what if you just threw your hiking gear into your laptop bag without taking out the computer first? You don't need a laptop on a mountain, and carrying it'll just slow you down.
Go to the Settings menu. In the Apps list, there is a tab labelled Running, which lists all currently active apps. One at a time, you can view each app and hit Stop. In this process, be cautious; you only want to stop apps you originally installed! The list of running apps also includes processes that are components of your device's Operating System. So the rule is, if you don't recognize it as something you deliberately added to your device, you probably shouldn't touch it.
5. Uninstall the app and download it again
This is the final basic step in any software troubleshooting process. It's usually effective when all else has failed. You do, of course, need to be sure you're going to be able to download it again! Make sure you know your Google Play account information to reinstall apps purchased through that marketplace. You may need to contact Amazon Android AppStore support for assistance reinstalling games from their store.
To uninstall an app, go to the Settings menu and find your app. Tap the button marked Uninstall.
