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.

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 ⭐

My Google account was cloned without my knowledge & permission. I spent the last 2 year's frustrated with technology & unable to figure out how / what was going on in the background of my phone due to a firewall partition. With FREE trial I was able to identify & figure out how to [undo] the rewritten script & what programs had been compromised. I'm not the I. T. type & didn't know what the Play Store was 2 year's ago, but thanks to this app I was finally able to solve the problem. Thank you!

I would have given it 5 stars easily if this app hasn't been such a pain in the *ss. I emailed them, but they seem to have died, probably, there was no answer. The app crashes or simply turns off every minute. I have to keep going to the settings every 1 minute and switch the home button of my phone and choose their app. So yeah, I'm uninstalling the app.

I got problem , when i change the default assist app, this app doesn't know that I changed it at all , and keep show message "You recently visited the system settings, where you could change the default assist app. However, you didn't choose the Developer Assistant. Would you like to repeat?" OnePlus 7 pro Android 11

Could you please write texts that make any sense? "In this limited mode, your assistant can be a bit sleepy. However, when awake, he will stay on duty." Are you telling me I need to buy a licence to use this or are you telling me I need to do something else? The same thing goes for the "intro" which makes absolutely zero sense. What is your goal here? Be as unclear as possible?

I've used it before but for some reason it's not working. I installed it.It says go to your settings to enable text and screen capture on my samsung. I go to the screen.I toggle those things on.They were actually turned on already.And then when I go back the app tells me.I didn't complete the action. There's nothing I can do on my side.I've gone back and forth many , many times. All I can do is cancel or go back to the settings screen completely Completely stuck. It's a good app But not working

I alpha/beta test many applications. Developer Assistant makes it easier to give BugReports, especially when I can find the bug 🪲 on my own. I'm also sure it's easier for the application developer, that gets more exact BugReports, and if i found the bug, a huge "help", when a alpha/beta user (like myself), get a chance to "show off" and tell them what's wrong i their alpha/beta 🤘🏼

Its definately a great app but currently I am rating this 3 stars coz ,after updating my OnePlus 7T Pro to Oxygen OS 11 (Android 11) , this app fails to detect change in the assistant. I don't know either it's app's issue or oxygen os , but I can't get it working , EDIT :- Got it working , but have to manually search in settings , default assistant app, instead of digital assistant , both options are present in settings but 'deafult assistant app' actually has effect
