a library for android which can help you to find heavy methods in your code when your app blocked, base on BlockCanary.

What's the difference between BlockCanaryEx and BlockCanary

  • BlockCanaryEx java runtime code are modified form BlockCanary, ui and features are mostly same;
  • BlockCanaryEx add MethodSampler, knows every method's execute info (like cost-time, called-times...) when blocked;
  • BlockCanaryEx focus on the method which cost most of time when your app blocked, and display it directly to developer;
  • add gc sampler,we can know whether and when gc happened when we blocked.

Download

root build.gradle

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0' //version must >= 1.5.0
        classpath 'com.letv.sarrsdesktop:BlockCanaryExPlugin:0.9.6'
    }
}

model build.gradle

apply plugin: 'blockcanaryex'
debugCompile 'com.letv.sarrsdesktop:BlockCanaryExJRT:0.9.6.1'
releaseCompile 'com.letv.sarrsdesktop:BlockCanaryExJRTNoOp:0.9.6'
testCompile 'com.letv.sarrsdesktop:BlockCanaryExJRTNoOp:0.9.6'

Basic Usage

init BlockCanaryEx before other method when your application created

public class TestApplication extends Application {
    @Override
    public void onCreate() {
        boolean isInSamplerProcess = BlockCanaryEx.isInSamplerProcess(this);
        if(!isInSamplerProcess) {
            BlockCanaryEx.install(new Config(this));
        }
        super.onCreate();

        if(!isInSamplerProcess) {
            //your code start here
        }
    }
}

done, now BlockCanaryEx be enabled when you app in debug mode.

Advance Usage

BlockCanaryEx do method sample by inject MethodSampler into your code when compile time, the scope to inject MethodSampler is the src of your project and subProject by default. projectLocalDep, subProjectLocalDep, externalLibraries is ignored. If you want to change the scope to watch more method performance, you can do the config in gradle.

  apply plugin: 'blockcanaryex'

  block {
      debugEnabled true //enable MethodSampler when debug mode, default true
      releaseEnabled false //enable MethodSampler when release mode, default false
      excludePackages [] //exclude the package you don't want to inject MethodSampler, eg: ['com.android', 'android.support']
      excludeClasses [] //exclude the class you don't want to inject MethodSampler
      includePackages [] //only include the package you want to inject MethodSampler, packages which don't included will not be injected

      scope {
          project true //inject MethodSampler for app project, default true
          projectLocalDep false //inject MethodSampler for app libs(eg: .jar), default false
          subProject true //inject MethodSampler for subProject of app project, default true
          subProjectLocalDep false //inject MethodSampler for subProject libs, default false
          externalLibraries false //inject MethodSampler external libs, default false
      }
  }

you also can override more Config method to customize BlockCanaryEx runtime

  public class TestApplication extends Application {
      @Override
      public void onCreate() {
          super.onCreate();
          BlockCanaryEx.install(new Config(this) {
              /**

               */
              public Looper provideWatchLooper() {
                  return Looper.getMainLooper();
              }

              /**

               */
