About this app

A powerful debugging app for Android. Developer Assistant makes debugging native Android apps as simple as debugging web pages using Chrome’s Developer Tools. It allows you to inspect the View hierarchy, verify Layout, Style, preview Translations and more. Everything can be done directly from the mobile device. Works for most Android apps.

Developer Assistant uses a mixture of official APIs and sophisticated heuristics in order to show at runtime more than possible for other tools. It’s tailored to increase productivity of professionals like Developers, Testers, Designers and Power Users in their day to day geeky tasks.

Developer Assistant is… right, the assistant app, you can invoke it at any time by a simple gesture like long pressing the home button.

INSPECT ALMOST ANY ANDROID APP

Developer Assistant can inspect Android applications based on official Android SDK. It supports also web-based apps and websites rendered by Google Chrome web browser. Support for other kinds of apps can be limited.

KEEP CALM & PRIVACY

Developer Assistant doesn’t require root or any specific requirements. It respects system security and user privacy. Any data collected from a screen is processed locally (offline). Apps and views declared as secure are respected, Developer Assistant even can’t access their content. Android assistant apps have access to screen data only after manually invoked by a user.

WHAT YOU GET FOR FREE

A 30day trial of probably the most advanced assistant app dedicated to Android Developers, Testers, Designers and Power Users. After this period, decide: get a professional license or stay with free, a bit limited, however still usable assist app.

CHECK CURRENT ACTIVITY

Developers can check class name of a current activity, especially helpful for larger projects. Testers will appreciate a unified solution to access the app version name, version code along with common actions like ‘app info’ or ‘uninstall’.

INSPECT VIEW HIERARCHY

Testers writing automation tests and developers chasing bugs can inspect hierarchy of elements displayed on the screen, directly from the mobile device. The concept is similar to the inspection of web pages with well-known dev tools shipped with the leading web browsers.

✔ Inspect view identifiers, class names, text style or color.
✔ Preview the best matching layout resources displayed next to their root views.

VERIFY LAYOUT

Designers, testers and developers can finally check size and position of various elements presented directly on the mobile device. Did you ever wonder what is the exact distance of a given button to a given text label on a particular device? Or maybe, what is the size of a particular element in density points? Developer Assistant provides a toolkit to help verify and satisfy requirements from designers like the pixel or rather the DP perfect design.

SEE CONTEXT OF TRANSLATIONS

Developer Assistant gives translation offices possibility to display translation keys next to text elements, directly on a mobile device. Translators get what’s the most important in order to provide a quality translation: the context where a given text is used.

✔ Translation keys displayed next to text elements.
✔ Translations for other languages can be previewed (no need to change the language of a mobile device).
✔ Minimum and maximum length among existing translations.

AND MORE...

Developer Assistant is under development, stay tuned for new features to come!

The app told me to wait for more than 30 minutes to show some internals for the selected object on the screen, then my phone couldn't take screenshot. I waited the 30+ minutes (in one case about an hour with app open at all times), the promised information wasn't shown. Then the timer would reset if I changed to a different tab. I don't know if you consider this normal mechanics, but the timer could easily be dropped down to 30 seconds (most ads are). The info's cut off too I have changed to 3 ⭐

Hi Jon, The idea is to give a user a chance to select his favourite tab, then use it without any limitations even with the free version of the app. If you are using the free version and one month of unlimited usage passed, then you will be limited from changing tabs too often (they can be changed max one time per hour).

It didn't work on my Redmi 6A, I did all the necessary steps like setting it as default assist app and giving all the permission it needed but I'm still unable to run it. I tried long pressing the home button and did the alternative swipe action but none of those two works. :( I would suggest to add a floating navigation instead where we can choose to run, pause, and stop the app. since it's more simple and convenient than remapping button to start this app.

Great App. Is good for loading it onto older family members to help walk them thru certain scenarios. Also helps keep me on track with tasks, additionally it's ui flows smoothly and has many different features that are easily available as well as descriptions of actions if and then. Amazing for the new user and the natives.

What's new

✔ The Element tab presents matching XML resources like layouts, styles, colors, drawables (possible thanks to the vastly improved heuristics which allow Developer Assistant to understand inspected apps better than before).
✔ Assist app setup wizard has been refreshed, covers cases related to the Android 10 gestures and custom button mappings seen on selected devices.
