Android Remote Debugger - remote debugging Android applications

Debugging is an important step in software development. Search and bug fixes allow you to develop quality products.

In this article I want to talk about debugging exactly Android applications. Android Studio provides us with various profiling tools, such as:

• logcat is a tool for viewing application logs, including crash exceptions. It can be used both in Android Studio and in the terminal, via adb;
• Android profiler is a powerful tool that allows you to view all network requests, CPU, memory and battery usage.

There are also many third-party solutions that allow you to view network traffic, databases, shared preferences, etc.
All of these tools have advantages and disadvantages. Their minuses include the following:

• many dependencies of various tools;
• complexity of use - as a rule, all tools are focused on developers and inconvenient for other team members, for example, testers, analysts or back-end developers. Typically, the latter have to pull the android developers to view any logs;
• Mandatory connection of the phone to the computer, for example, via a usb cable.
