Tiny Dancer

A real time frames per second measuring library for Android that also shows a color coded metric. This metric is based on percentage of time spent when you have dropped 2 or more frames. If the application spends more than 5% in this state then the color turns yellow, when you have reached the 20% threshold the indicator turns red.

New Double tap overlay to hide!

Getting started

In your build.gradle:

 dependencies {
   debugCompile 'com.github.brianPlummer:tinydancer:0.0.7'
 }

In your DebugApplication class:

public class DebugApplication extends Application {

  @Override public void onCreate() {
   TinyDancer.create()
             .show(this);
             
   //alternatively
   TinyDancer.create()
      .redFlagPercentage(.1f) // set red indicator for 10%
      .startingGravity(Gravity.TOP)
      .startingXPosition(200)
      .startingYPosition(600)
      .show(this);

   //you can add a callback to get frame times and the calculated
   //number of dropped frames within that window
   TinyDancer.create()
       .addFrameDataCallback(new FrameDataCallback() {
          @Override
          public void doFrame(long previousFrameNS, long currentFrameNS, int droppedFrames) {
             //collect your stats here
          }
        })
        .show(this);
  }
}

You're good to go! Tiny Dancer will show a small draggable view overlay with FPS as well as a color indicator of when FPS drop. You can double tap the overlay to explicitly hide it.
