配置 

build.gradle

dependencies {
debugCompile 'com.squareup.leakcanary:leakcanary-android:1.4-beta2'
releaseCompile 'com.squareup.leakcanary:leakcanary-android-no-op:1.4-beta2'
testCompile 'com.squareup.leakcanary:leakcanary-android-no-op:1.4-beta2'
}

 

使用说明

建立RefWatcher全局变量

使用RefWatcher去监控引用，Activity,Fragment等中的内存泄漏

例子

第一步：定义RefWathcher全局变量

package com.app.client;

import android.app.Application;
import android.content.Context;

import com.squareup.leakcanary.LeakCanary;
import com.squareup.leakcanary.RefWatcher;

public class MyApplication extends Application {

public static RefWatcher getRefWatcher(Context context){

MyApplication application = (MyApplication) context.getApplicationContext();
return application.refWatcher;
}

private RefWatcher refWatcher;

@Override
public void onCreate() {
super.onCreate();
refWatcher = LeakCanary.install(this);
}
}

 

第二步：监控Activity中的内存泄漏问题

package com.app.client;

import android.app.Application;
import android.content.Context;

import com.squareup.leakcanary.LeakCanary;
import com.squareup.leakcanary.RefWatcher;

public class MyApplication extends Application {

public static RefWatcher getRefWatcher(Context context){

MyApplication application = (MyApplication) context.getApplicationContext();
return application.refWatcher;
}

private RefWatcher refWatcher;

@Override
public void onCreate() {
super.onCreate();
refWatcher = LeakCanary.install(this);
}
}

 

Manifest配置

<application
android:name=".MyApplication"
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme" >
<activity android:name=".MainActivity" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
