Telescope

A simple tool to allow easy bug report capturing within your app.

Usage

Place a TelescopeLayout at the root of your hierarchy.

Add a callback to the view group with setLens(Lens). Telescope provides two default implementations:

  • EmailLens: Compose an email with the provided addresses and subject (optional).
  • EmailDeviceInfoLens: Enhances EmailLens by pre-populating the email body with app and device info

Screenshots will be stored on the external storage in your app's private directory. To have Telescope clean up the screenshots folder, call TelescopeLayout.cleanUp(Context). Ideally, this would be called in the onDestroy() method of your Activity or Fragment.

If you are using the Gradle-based build system, you can wrap this view group around your activity layouts only in the debug builds.

See the u2020 project for a more advanced example.

Permissions

Pre-KitKat, WRITE_EXTERNAL_STORAGE is required for saving screenshots. Screenshots can be disabled using the configuration options below.

Configuration

The view group can be configured as follows:

  • Set the number of fingers to trigger with app:telescope_pointerCount / setPointerCount(int)
  • Set the progress color with app:telescope_progressColor / setProgressColor(int)
  • Change the screenshot method with app:telescope_screenshotMode / setScreenshotMode(ScreenshotMode)
  • Screenshot children only with app:telescope_screenshotChildrenOnly / setScreenshotChildrenOnly(boolean)
  • Set the screenshot target withsetScreenshotTarget(View)
  • Disable vibration with app:telescope_vibrate / setVibrate(boolean)
