Developer Assistant

A powerful debugging app for Android. Developer Assistant makes debugging native Android apps as simple as debugging web pages using Chrome’s Developer Tools. Allows you to inspect the View hierarchy, verify Layout, Style, preview Translations and more. Everything can be done directly from the mobile device. Best suited for apps based on Views and Fragments, with limited support of technologies like Android Compose, Flutter and Web apps.

Developer Assistant uses a mixture of official Assist and Accessibility API, augmented by sophisticated heuristics. This combination helps 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 NATIVE AND HYBRID ANDROID APPS

Developer Assistant can inspect Android applications based on the official Android SDK. It is best suited for apps based on Views and Fragments. Has also limited support for Android Compose, Flutter, Web-based apps and webpages.

KEEP CALM & PRIVACY

Developer Assistant DOES NOT require root. It respects system security and user privacy. Any data collected from the screen is processed locally (offline) and only on explicit user request - when the assist function is invoked. For basic operation, Developer Assistant needs to be chosen as the default Digital Assistant app. Optionally, it may be granted with Accessibility Service permission (which increases accuracy of inspection for non standard apps).

WHAT YOU GET FOR FREE

A 30 day 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 application.

CHECK CURRENT ACTIVITY

Developers can check the 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 the 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 the 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 the 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.
