Android apps always face the challenge of CPU and memory threshold; therefore, the library aims to detect, analyze, and optimize performance.

Detect tools

adb shell top and python script

1: check the process name of apps, for example, com.jack.performance

adb shell ps | grep com.jack.performance

2: get the consumption of CPU and memory

adb shell top -p {pid} -H

3: Using python script to capture datas, the data will be saved in the Desktop file

source ./venv/bin/activate
python getTop.py com.jack.performance

4: generate the chart figure

source ./venv/bin/activate
python3 cpu-chart.py xxx.txt

Perfetto

Option 1: Capture data by command line

1: setup probes(injection), then save the config.gpx

2: Copy and save the config.gpx

real file -> /configure/cpu-config.gpx

3: execute command

cat config.pbtx | adb shell perfetto -c - --txt -o /data/misc/perfetto-traces/trace.pftrace

4: pull the trace file

adb pull /data/misc/perfetto-traces/trace.pftrace
