利用 LeakCanary 来检查 Android 内存泄漏 6.0以上版本空指针解决

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

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...
  }
}
