# MemoryLeakDetector
[简体中文版说明 >>>](/README_cn.md)

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
```gradle
allprojects {
repositories {
maven { url 'https://jitpack.io' }
}
}
```
Step 2: Add the dependency
```gradle
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)
```java
// 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$"
);
```
```java
// Using MemoryLeakDetector to monitor current process
Raphael.start(
Raphael.MAP64_MODE|Raphael.ALLOC_MODE|0x0F0000|1024,
"/storage/emulated/0/raphael", // need sdcard permission
null
);
```
```shell
## broadcast command for specified so
adb shell am broadcast -a com.bytedance.raphael.ACTION_START -f 0x01000000 --es configs 0xCF0400 --es regex ".*libXXX\\.so$"
```
```shell
## broadcast command （RaphaelReceiver component process）
adb shell am broadcast -a com.bytedance.raphael.ACTION_START -f 0x01000000 --es configs 0xCF0400
```
Step 4: Print result
```java
// code control
Raphael.print();
```
```shell
## broadcast command
adb shell am broadcast -a com.bytedance.raphael.ACTION_PRINT -f 0x01000000
```
Step 5: Analysis
```shell
## 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/
```
```shell
## analysis maps
## -m: maps file path
python3 library/src/main/python/mmap.py -m maps
```
Step 6: Stop monitoring
```java
// code control
Raphael.stop();
```
```shell
## broadcast command
adb shell am broadcast -a com.bytedance.raphael.ACTION_STOP -f 0x01000000
```
