AndroidStudio MAT LeakCanary 内存分析之 LeakCanary

现在我们换一种更清晰方便的方式：LeakCanary https://github.com/square/leakcanary

首先将LeakCanary绑在我们的app上 
build.gradle

dependencies{
 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'
 }

public class SunApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        Global.mContext = SunApplication.this.getApplicationContext();
        initializeLeakDetection();
    }

    private void initializeLeakDetection() {
        if (BuildConfig.DEBUG) {
            LeakCanary.install(this);
        }
    }
}

Manifest 添加权限WRITE_EXTERNAL_STORAGE、不然会发生错误、如下代码 
android 6.0以上另外获取权限、详情请见我的博文 Android 6.0 最简单的权限获取方法 RxPermition EasyPermition

  <!--Required by Debug.startMethodTracing() -->
    <!--LeakCanary need this Unable to resume activity
    {com.rvitemtouch.sun.sundagger2application/com.squareup.leakcanary.internal.DisplayLeakActivity}:
    java.lang.UnsupportedOperationException: Could not create leak directory
    /storage/emulated//Download/leakcanary-com.rvitemtouch.sun.sundagger2application-->
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

安装好了、运行app、继续将之前写的（Android AndroidStudio MAT LeakCanary 内存分析之 AndroidStudio 内存泄漏分析 Memory Monitor）

Activity反复翻转屏幕、导致内存泄漏

出现内存泄漏提示

Leaks 会伴随我们的app一块install、那么打开leaks、等待一会

找到我们定位的泄漏 打开

就能看出详细的链式结构、上面写的很明白了、正如之前我们所料 
是Memory..Activity的引用被Runnable占用了
