MemoryLeakDetector is a native memory leak monitoring tool developed by Xigua video android team. It has simple access, wide monitoring range, excellent performance and good stability. It is widely used in native-memory-leak-governance of ByteDance's major apps, and the benefits are significant!

Apps using MemoryLeakDetector

Get started

Step 1: Add the JitPack repository to your build file

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

Step 2: Add the dependency

dependencies {
    implementation 'com.github.bytedance:memory-leak-detector:0.2.1'
}

Step 3: Add code for simple usage (This step is not necessary for using broadcast control)

// Using MemoryLeakDetector to monitor specified so
Raphael.start(
    Raphael.MAP64_MODE|Raphael.ALLOC_MODE|0x0F0000|1024,
    "/storage/emulated/0/raphael", // need sdcard permission
    ".*libxxx\\.so$"
);
// Using MemoryLeakDetector to monitor current process
Raphael.start(
    Raphael.MAP64_MODE|Raphael.ALLOC_MODE|0x0F0000|1024,
    "/storage/emulated/0/raphael", // need sdcard permission
    null
);
## broadcast command for specified so
adb shell am broadcast -a com.bytedance.raphael.ACTION_START -f 0x01000000 --es configs 0xCF0400 --es regex ".*libXXX\\.so$"
## broadcast command (RaphaelReceiver component process)
adb shell am broadcast -a com.bytedance.raphael.ACTION_START -f 0x01000000 --es configs 0xCF0400

Step 4: Print result

// code control
Raphael.print();
## broadcast command
adb shell am broadcast -a com.bytedance.raphael.ACTION_PRINT -f 0x01000000

Step 5: Analysis

## analysis report
##   -r: report path
##   -o: output file name
##   -s: symbol file dir
python3 library/src/main/python/raphael.py -r report -o leak-doubts.txt -s ./symbol/
## analysis maps
##   -m: maps file path
python3 library/src/main/python/mmap.py -m maps

Step 6: Stop monitoring

// code control
Raphael.stop();
## broadcast command
adb shell am broadcast -a com.bytedance.raphael.ACTION_STOP -f 0x01000000
