Tailor

简体中文版说明 >>> Tailor is a general-purpose hprof cropping and compression tool developed by Xigua video android team. Through it, a mini hprof file can be dump directly during exception handling. There is no sensitive information in the file。More importantly, the file is small but the data is relatively complete, which is very suitable for offline analysis of oom and other exceptions

Apps using Tailor

Get started

Step 1: Add the JitPack repository to your build file

gradle

allprojects {
    repositories {
        maven { url 'https://jitpack.io' }
    }
}

Step 2: Add the dependency

gradle

dependencies {
    implementation 'com.github.bytedance:tailor:1.1.6'
}

Step 3: Add code for simple usage

java

if (e instanceof java.lang.OutOfMemoryError) {
    String path = Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator + "mini.hprof";
    try {
        Tailor.dumpHprofData(path, true);
    } catch (IOException ex) {
        ex.printStackTrace();
    }
}

java

// Crop and compress the existing hprof files directly
Tailor.cropHprofData(source, target, true);

Step 4: Upload data

## !!! App needs to implement upload logic by itself

Step 5: Process data (Python version >= 3.5)

bash

## Data recovery
python3 library/src/main/python/decode.py -i mini.hprof -o target.hprof

bash

## Hprof verify
