About Developer Tools
Using this app you can see which resource qualifiers that are being used, which system features that are available, and see details about the display and its sizes.
Also I wanted to create an app where everything I needed was just one click away. The full list of features:
- See resource qualifiers in use
- See available system features
- See screen dimensions in dp, pt, in, sp, px, mm
- Start Dalvik Explorer (third party app)
- Start aLogcat (third party app for viewing logcat)
- Start ManifestViewer (third party app for viewing AndroidManifest.xml ++)
- Start Clean Status Bar (third party app for taking tidying up status bar for screenshots]
- Go directly to the Android 4.3's permission manager (App Ops)
- Go directly to the device's developer settings
- Go directly to the list of installed applications
Works for Android 1.5 and up. Doesn't need any permissions to run. Please give me a word if there's something you'd like to see included in this app. :)
I have open sourced the version 2 of the app. It can be found at https://github.com/roys/java-android-developertools .
