Debugging is an essential part of swift app development. Android Studio provides a comprehensive debugger that allows you to identify and fix errors in your code. In this guide, we'll explore how to use the Android Studio debugger to debug your app.
To begin debugging, you need to enable debugging on your device or emulator. If you're using a connected device, make sure to enable debugging in the device developer options. For the emulator, debugging is enabled by default. Next, run a debuggable build variant that includes debuggable true in the build configuration.
Once you've set up your project for debugging, it's time to start setting breakpoints. Breakpoints are essential for identifying where errors occur in your code. You can set line breakpoints or method breakpoints, depending on your needs.
When setting breakpoints, select a device from the target device menu and click Debug. If your app is already running on the device, you'll be prompted to switch from Run to Debug mode. To keep the same instance of the app running, cancel debugging and attach the debugger instead.
The Android Studio debugger provides several features for inspecting variables and evaluating expressions at runtime. The Debug window includes execution and navigation toolbar, thread selector, evaluation and watch expression entry, stack display, variables pane, and more.
You can also select a debug type to use for your project. There are three options: Detect Automatically, Java Only, and Native Only (available only with C/C++ code). The Detect Automatically debug type is the default and automatically selects the best option based on whether your project includes Java or C/C++ code.
Native debugging works on devices that support run-as and have ptrace enabled. You can check for these requirements by running commands on the ADB shell.
In addition to line breakpoints, you can also set method breakpoints that pause the execution of your app when it enters or exits a specific method. This is useful for identifying where errors occur in your code.
By following these steps and using the features of the Android Studio debugger, you'll be able to identify and fix errors in your swift app development project.
