Bugjaeger Mobile ADB – Develop & Debug via USB OTG - Interview with the developer of a fantastic app

Did you have any prior development or coding experience?

I’ve been developing Android apps for a couple of years now. I’m a self-taught programmer and the first applications that I’ve developed were reporting tools for a company in the financial sector. Developing Android apps was just a free time activity at first. Later it became my main focus. I’m really enjoying it. I developed various apps related to image processing, audio, or even industry automation. Bugjaeger is one of my tech tools.

What was the most challenging aspect of developing mobile app?

Getting a better understanding of the underlining technologies and combine them to create the app. I needed to spend a lot of time studying the sources of the Android system before I could write even one line of code. Additionally, the app is a combination of Java/Kotlin code and native C/C++ code, which slows down the development.

My name is Roman Sisik. I'm an app developer, entrepreneur and tech blogger.
I created the Bugjaeger app for all tech-savvy Android enthusiasts out there. I'm the owner of sisik.eu blog where I write about all kinds of mobile technologies and embedded systems.

Name a few of your favorite apps and reason you love them.

Waze – I like the accuracy. The app really helped me to avoid traffic and find the fastest way. It saved me so much time.
Audible app – Listening to audio books is my favorite activity when driving or doing sports. But the app itself is also handy and easy to use.
WhatsApp – Reliable, fast, and easy to use. And I also like that it offers a desktop version seamlessly synchronized with the app.

How long have you been working on this app?

I started to work on Bugjaeger during the summer of 2017 and I published the initial version end of October of the same year. Since then there were so many changes – various new features, UI improvements, bug fixes.

What need of the user did you have in mind when developing this app?

I wanted to give the user who is interested in Android technology the possibility to use the tools that are normally only available on the development machine directly from his phone. The tech-savvy user should be able to do tasks like executing scripts, checking logs, taking screenshots without even using his laptop. Just with a couple of taps on his phone/tablet.

In what way do you think your app is better than similar apps on the market? Please describe in detail what innovation you think you bring and what you are proud of in your app.

I think enabling access via USB OTG (not only WiFi), so that the user can use the app in a similar way as the desktop tools he is already familiar with, was one of the differentiating things.

Another thing is streamlined commands packed into a mobile interface, so that instead of typing in and executing various ADB shell commands, you just need to do a couple of taps.

One additional thing is packing the two important development and flashing tools (fastboot + ADB) into one mobile app. So that the user can have access to the functionality of both tools (which is I think are related) from one app.

What are your future plans and expected features of the coming new versions of this app?

There are so many things that I would like to implement. First, there will probably be some improvements and additional features related to file manipulation, fastboot and logs.

I also would like to give the user more configuration options, so that he can tweak the app according to his preferences.

Later I would like to give users more options to share scripts, logs, or other content extracted by the app with each other.

Assuming new users of your app are reading this page. What do you want to ask them to do (contact you about X, Share the app, etc.)?

The app has a bit of a learning curve, so I would suggest that the users check my blog posts with “Bugjaeger” tag. This should help them see all the possibilities that the app offers.

If they like the app, I’d really be glad when they would tell about it to their tech-savvy friend who’s interested in Android-related stuff.

Additionally, if they have suggestions or issues, they should really let me know. Explaining the suggestions or issues that they have in detail can really help to improve the app.

Bugjaeger Mobile ADB – Develop & Debug via USB OTG

About App:

Bugjaeger tries to give you the expert tools used by Android developers for better control and deep understanding of your Android device internals.

Multitool that can save you the hassle of carrying a laptop.

If you're an Android power user, developer, geek, or hacker, this app might be something for you.

How to use

1.) Enable developer options and USB debugging on your target device
Note: On Huawei devices you might first need to turn on USB tethering before you enable USB debugging
2.) Connect the device where you've installed this app to the target device via USB OTG cable
3.) Allow the app to access USB device and make sure the target device authorizes USB debugging

Inspecting Android device internals, running shell scripts, checking logs, making screenshots, inspecting backup files, and many more tasks that are normally done on your laptop can now be performed directly between 2 mobile devices.

This app works as sort of Android to Android ADB (Android Debug Bridge) - it offers some features similar to ADB (Android Debug Bridge) and Android Device Monitor, but instead of running on your development machine, it runs directly on your Android device.

You connect your target device through USB OTG cable or through WiFi and you'll be able to play around with the device.

ADB protocol is supported also by Android devices other than phones & tablets. That means that you should also be able to control your Android TV, Wear OS watch, or even Raspberry Pi with Android Things OS.

Main features:

  • running custom shell scripts on the target device
  • remote interactive shell
  • reading, filtering and exporting device logs (logcat)
  • pull APK files
  • creating and restoring backups, inspecting and extracting the content of backup files
  • capturing screenshots
  • performing various commands for controlling your device (rebooting, going to bootloader, rotating screen, killing running apps, ...)
  • uninstalling and installing packages, checking various details about installed apps
  • copying apps between phones
  • monitoring the processes, showing additional information related to processes, killing processes
  • showing various details about Android version(e.g., SDK version, Android ID,..), Linux kernel, CPU, abi, display
  • showing battery details (like e.g., temperature, health, technology, voltage,..)
  • file management - pushing and pulling files from a device, browsing the file system
  • search and connection to Android devices on your network that configured adbd to listen on port 5555
  • reading bootloader variables & info via fastboot protocol (e.g. dump some hw info, security state, or if the device was tampered)
  • exec fastboot commands
  • Requirements

    • Enabled USB debugging in Developer options and authorise the development device
    • Fastboot protocol support if you want bootloader info (note that the amount and type of information that can be displayed via fastboot will vary between different devices)
    • Please note
      This app uses the normal way of communicating with Android devices which requires authorisation.
      The app does not bypass Android's security mechanisms or anything similar!
      This also means the app won't be able to perform some privileged tasks on non-rooted devices.
