The LeakCanary plugin provides developers with Flipper support for [LeakCanary](https://github.com/square/leakcanary), an open source memory leak detection library.
|
|
|
|
## Setup
|
|
|
|
Note: this plugin is only available for Android.
|
|
|
|
### Android
|
|
|
|
First, add the plugin to your Flipper client instance:
|
|
```java
|
|
import com.facebook.flipper.plugins.leakcanary.LeakCanaryFlipperPlugin;
|
|
|
|
client.addPlugin(new LeakCanaryFlipperPlugin());
|
|
```
|
|
|
|
Next, build a custom RefWatcher using RecordLeakService: (see [LeakCanary docs](https://github.com/square/leakcanary/wiki/Customizing-LeakCanary#uploading-to-a-server) for more information on RefWatcher)
|
|
```java
|
|
import com.facebook.flipper.plugins.leakcanary.RecordLeakService;
|
|
|
|
RefWatcher refWatcher = LeakCanary.refWatcher(this)
|
|
.listenerServiceClass(RecordLeakService.class);
|
|
.buildAndInstall();
|
|
```
|
|
|
|
## Usage
|
|
|
|
Leaks detected by LeakCanary will appear automatically in Flipper. Each leak will display a hierarchy of objects, beginning from the garbage collector root and ending at the leaked class.
|
|
Selecting any object in this list will display contents of the object's various fields.
