a library for android which can help you to find heavy methods in your code when your app blocked, base on 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;
- BlockCanaryEx add gc sampler，we can know whether and when gc happened during we blocked.
- add view performance sampler, we can know the detail about view measure, layout, draw during we blocked.
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:0.9.9.5'
}
}model build.gradle
apply plugin: 'blockcanaryex'debugCompile 'com.letv.sarrsdesktop:BlockCanaryExJRT:0.9.9.4'
releaseCompile 'com.letv.sarrsdesktop:BlockCanaryExJRTNoOp:0.9.9.4'
testCompile 'com.letv.sarrsdesktop:BlockCanaryExJRTNoOp:0.9.9.4'init BlockCanaryEx before other method when your application attachBaseContext
public class TestApplication extends Application {
@Override
public void attachBaseContext(Context context) {
super.attachBaseContext(context);
boolean isInSamplerProcess = BlockCanaryEx.isInSamplerProcess(this);
if(!isInSamplerProcess) {
BlockCanaryEx.install(new Config(this));
}
if(!isInSamplerProcess) {
//your code start here
}
}
}done, now BlockCanaryEx be enabled when you app in debug mode.
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
}
