Trace

Trace is a gradle plugin for android project to trace java method invocation, it uses the Transform API and Javassist to manipulate the bytecode, and print the java method with elapsed time to logcat.

Getting Started

Configure this build.gradle like this:

buildscript {
    repositories {
        mavenLocal()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0' // Or higher version
        classpath 'com.sdklite.trace:gradle-plugin:0.0.2' // HERE
    }
}

Then apply the trace plugin below the android plugin

apply plugin: 'com.sdklite.trace'

Finally, build your project and install the application to your android device, then you can filter the logcat like this:

adb logcat -s trace

Performance optimization

Trace gradle plugin is useful and convinient for performance optimization by dumping the trace log via logcat:

1. Clean logcat

   adb logcat -c

2. Launch app

3. Dump trace log

   adb logcat -d -s trace | awk -F: '{print $NF}' | awk '{printf "%s, %s\n", $1, substr($2, 2)}'

   or filter by elapsed time

   adb logcat -d -s trace | awk -F: '{print $NF}' | awk '{et=strtonum(substr($2,2)); if (et > 30) { printf "%s, %s\n", $1, et}}'
