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'}

使用說明

建立RefWatcher全局變量

使用RefWatcher去監控引用，Activity,Fragment等中的內存泄漏

例子

第一步：定義RefWathcher全局變量

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

第二步：監控Activity中的內存泄漏問題

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;@Overridepublic 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>

第三步：生成的泄漏結果圖
