The error message will state the name of the file and line number causing the error. Scroll through the Logcat messages until you find a line containing one of your app's files is highlighted in blue. Either way, the Logcat will record the reason for the crash.īut how do you identify which error is causing the app to crash? Well, the best place to start is to find an error relating to a specific bit of your code. Maybe your app crashes the moment it loads, or perhaps the app crashes when you attempt a certain action. You can now refer to the error messages that appear in the Logcat at the moment your app crashes. We can filter the messages to see which relate to errors by changing one of the Logcat dropdown menus from 'Verbose' to 'Error'. You will likely see a continuous stream of messages. So, load up your app and expand the Logcat. The Logcat is best used while your app is running on a virtual device. You can access the Logcat by clicking the tab in the bottom left corner.

Android Studio also contains a Logcat which displays system messages (including errors). Red errors are not the only way of spotting bugs in your code.

Some good places to check are Stack Overflow, the Android Developers website and your trusty Coders' Guidebook. That's where Google comes in! Simply copy and paste the Android Studio error description into Google and see what the Android community can come up with. While not all resolutions are that simple, chances are somebody else has encountered the same error before and fixed it. To resolve this error, we can simply change the function to take Int as a parameter instead of Recipe. In the example below, recipeToShow is throwing a 'Type mismatch' error and Android Studio even shows what it was expecting (Int as a parameter instead of Recipe). If you hover over the error in Android Studio with your mouse then it should describe the issue. In which case, it may be time to turn to the great wide web for help. Maybe removing one error creates another, or perhaps the proposed solution just isn't relevant. Sometimes the suggested resolutions from Android Studio don't quite solve the problem.

Sometimes you need to rename the reference and fix a typo (like in this example), other times you may need to import a missing function or perform another task to get your code working. A drop-down menu will then appear with some possible fixes.

Simply select the red code then press the alt and enter keys on your keyboard. In addition to finding the error, Android Studio will often offer potential resolutions.

In this case, the phrase 'setContntView' is highlighted because of a typo. If you then open the file you will find the offending code highlighted in red. In the example below, it is the MainActivity.kt file that contains the bug. Simply press Project > app and scan the folders for files underlined in red. You must resolve all red warnings before your app will run. If Android Studio spots something that will crash your app then it will often highlight it in red. 1 - Find any red warningsĪndroid Studio is generally pretty good at finding bugs in your code.
