You can open the logcat and in the error section start reading the log error messages.
It is best to look at the logcat to find the exact point of error. This might sometimes help you automatically remember or recall what mistake was made and which part of the app is causing that. Suppose you have built an application with multiple activities or fragments or both then you need to observe and see which action causes the application to crash.
OutOfMemoryError – When an object cannot be allocated more memory by its garbage collector. IOException – Exceptions produced by failed or interrupted I/O operations. NullPointerException – When expecting from null variables, objects, or classes. To open Logcat Click View > Tool Windows > Logcat (Alt + 6 or from the toolbar window). Logcat window in Android Studio is used to display real-time system messages and messages that are added in the Log class of the app. In Android Studio one of the most used tools is Logcat. So, this is a very useful component for the app development because this Logcat dumps a lot of system messages and these messages are actually thrown by the emulator. Then, Logcat Window is going to help you to debug the output by collecting and viewing all the messages that your emulator throws. Suppose, you are running your application and the program crashes, unfortunately. Logcat Window is the place where various messages can be printed when an application runs. In this situation, the Logcat acts as our best friend. But my app still stops working or some features don’t work the way I want it to? #MESSAGES APP ANDROID CRASHING CODE#
Now the question is – We have written 100’s and 1000’s lines of error less codes or I should syntax error free code that compiles and runs without any problem. Runtime and Logical errors are the common ones and cannot be detected in the editor. Whereas we have many other kinds of errors that might cause our app not to work the way we want it to be. Because the editor only helps in detecting the syntax error in the code. Now we can write error-less code and our app should run, right? Well, NO. We can say that because the editor detects that in real-time and warns us with red underlining at that line. Well, in the above image we can see that the error occurs due to a closing bracket after orderLists in Line 58. We know that there’s an error since the editor automatically detects in real-time and highlights it in red color like this
While developing applications in Android Studio we might encounter many errors while writing code in the editor.
