How to solve crashes in Google Play Console? - crash

Question

In Google Play Console on the dashboard of your application there
is a graph with Crashes & ANRs.
What is the best practice to solve
crashes to provide the best service to your users? My application is
written in Python in Kivy framework.

Answer 1

Navigate to Quality -> Android Vitals -> Crashes and ANRs.
This lists each event and on the right you will see a "->" arrow labelled "View Details".
Click this, scroll down past the graph and you'll see the Stack traces.
This is what you need to look at to fix your code.
The top line will be the error, then it'll show the line of code where the error occurred, for example:
[code]
java.lang.NullPointerException:
at com.test.MyApp.doSomethingCool (MyClass.java:123)
at com.test.MyApp.somethingElse (AnotherClass.java:321)
[/code]
Here you have some null value causing an issue in the "doSomethingCool" function of your app and that code should be on line 123 of "MyClass.java".
The trace lines after that show what called that function that failed, so above, this is showing that "doSomethingCool" was called from function "somethingElse" on line 321 and that code is in "AnotherClass.java".
This example is for Java.
--Updated--
If you are coding in Python, then the stack trace may not show you where in your own code the problem lies. Instead your best bet is to search on Google for the top line error and hope that the answer is online.
Separately from stack trace analysis I would highly recommend that you place your project into source control with GIT or SVN, specifically so that you can see what changes might have caused an error.
Update your code in the repository only when it's working and then you will always have a safe saved version that is known as working. You can then easily compare your current code and see what changes might have caused an error. This is especially useful for Android, which regularly updates versions of shared libraries.
