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!

Min SDK

Tiny Dancer min sdk is API 16

Unfortunately this will not work on Android TV

Getting started

In your build.gradle:

 dependencies {

 debugCompile "com.github.brianPlummer:tinydancer:0.1.2"
 releaseCompile "com.github.brianPlummer:tinydancer-noop:0.1.2"
 testCompile "com.github.brianPlummer:tinydancer-noop:0.1.2"  
}

In your DebugApplication class:

public class DebugApplication extends Application {

 @Override public void onCreate() {

  TinyDancer.create()

  .show(context);

//alternatively
 TinyDancer.create()

 .redFlagPercentage(.1f) // set red indicator for 10%....different from default

 .startingXPosition(200)

 .startingYPosition(600)

 .show(context);

  //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(context);

}
 
}

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.
