10 Performance messen Laufzeiten Tacho Thaddäus Zoltkowski 10
11 Performance messen Laufzeiten Log long start = System.nanoTime(); /** Do things... */ Log.d(TAG, Doing took +(System.nanoTime()-start)); 11
12 Performance messen Laufzeiten Timing Logger TimingLogger timings = new TimingLogger(TAG, "murl"); /** Do cache */ timings.addsplit( cache"); /** Do load */ timings.addsplit( load"); /** and scale */ timings.addsplit( scale"); timings.dumptolog(); $> adb shell setprop log.tag.tttask VERBOSE TTTask D murl: begin D murl: 4 ms, cache D murl: 1819 ms, load D murl: 8 ms, scale D murl: end, 1831 ms 12

14 Performance messen Laufzeiten Traceview 14
15 Performance messen Laufzeiten Traceview 15
16 Performance messen Laufzeiten Systrace ab API Level 16 (4.1) 16

18 Performance messen Frames 18
19 Performance messen Frames (Blau) Draw is the time spent building display lists in Java. It indicates how much time is spent running methods such as View.onDraw(Canvas). 19
20 Performance messen Frames (ROT) Process is the time spent by Android s 2D renderer to execute the display lists. The more Views in your hierarchy, the more drawing commands must be executed. 20
21 Performance messen Frames (Orange) Execute is the time it took to send a frame to the compositor. This part of the graph is usually small. 21
