LeakCanary 是一个开源的在debug（Relese）版本中检测内存泄漏的java库,链接：

你也许会遇到如下类似错误

1.3. 在6.0预览版报错

* FAILURE:

java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.lang.String.equals(java.lang.Object)' on a null object reference

at com.squareup.leakcanary.HeapAnalyzer.findLeakingReference(HeapAnalyzer.java:160)

at com.squareup.leakcanary.HeapAnalyzer.checkForLeak(HeapAnalyzer.java:95)

at com.squareup.leakcanary.internal.HeapAnalyzerService.onHandleIntent(HeapAnalyzerService.java:57)

之前我们的配置也许是这样的：

dependencies { debugCompile 'com.squareup.leakcanary:leakcanary-android:1.3'

releaseCompile 'com.squareup.leakcanary:leakcanary-android-no-op:1.3'

}

在Application中：

publicclassExampleApplicationextendsApplication{

@OverridepublicvoidonCreate(){

super.onCreate();

LeakCanary.install(this);}}

新更新的SDK 1.5版本，已经完美解决、android6.0以上运行时权限，Notification无法弹出的问题，需要重新配置

build.gradle:

 dependencies {   debugCompile 'com.squareup.leakcanary:leakcanary-android:1.5'   releaseCompile 'com.squareup.leakcanary:leakcanary-android-no-op:1.5'   testCompile 'com.squareup.leakcanary:leakcanary-android-no-op:1.5' }public class ExampleApplication extends Application {  @Override public void onCreate() {    super.onCreate();    if (LeakCanary.isInAnalyzerProcess(this)) {      // This process is dedicated to LeakCanary for heap analysis.      // You should not init your app in this process.      return;    }    LeakCanary.install(this);    // Normal app init code...  }}
