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!
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 0xCF0400Step 4: Print result
// code control
Raphael.print();## broadcast command
adb shell am broadcast -a com.bytedance.raphael.ACTION_PRINT -f 0x01000000Step 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 mapsStep 6: Stop monitoring
// code control
Raphael.stop();## broadcast command
adb shell am broadcast -a com.bytedance.raphael.ACTION_STOP -f 0x01000000- Communicate on GitHub issues
