There are several ways to debug Java code. When developing, you can use the tools available in your IDE or debugger. Once the application is deployed to production, you can capture the logs or use an error monitoring solution. Let’s explore each of these ways in more detail. Debugging wi...
In order to debug from your device, we need to rely on adb logcat. Logcat is a command-line tool that dumps a log of system messages, including stack traces when the device throws an error and messages that you have written from your app with the Log clas...
The bytecode files contain all the information needed to run your application. The JVM (Java Virtual Machine) reads these files and uses JIT (Just In Time) compilation to execute them at runtime. So what’s inside a Java bytecode file? Huh? That’s what I wrote? This is the intermedia...

something in the packagecom.myproject(it’s on the 3rd line here), then scan to the end of the line to see where the code is (MyProject.java:17). That line will contain some code that callsFraction.getFraction. This is the starting point for investigation: What is passed togetFraction...
Eclipse:Eclipse is a popular Java IDE that provides a built-in debugger for analyzing stack traces. The debugger allows you to step through your code, set breakpoints, and examine variables and objects at runtime. IntelliJ IDEA:IntelliJ IDEA is another Java IDE that provides advanced debugging ...
As the runtime has access to all the capabilities of the phone, the JavaScript will do also. The JavaScript library will then act as a gateway between both worlds. Moreover, the good point of using this library is that your code will most of the time works as-is on the PhoneGap ...
