从MAT检测内存泄漏

Question

我正在使用内存分析器工具检测我的应用程序中的可能内存泄漏，下面是堆配置文件的图像，它说我有5个IntroActivity对象，下面是我的入侵性代码，我无法找到多次创建此对象的位置

public class IntroActivity extends AppCompatActivity {

    private ViewPager viewPager;
    private MyViewPagerAdapter myViewPagerAdapter=new MyViewPagerAdapter();
    private LinearLayout dotsLayout;
    private TextView[] dots;
    private int[] layouts;

    private Button btnSkip, btnNext;


    @Override

        super.onCreate(savedInstanceState);

        // Checking for first time launch - before calling setContentView()

        context=IntroActivity.this;
        // Making notification bar transparent
        if (Build.VERSION.SDK_INT >= 21) {
            getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
        }

    @Override

        super.onDestroy();


    }

任何人都可以帮助找到可能的泄漏任何帮助是适当的

不，你没有5个IntroActivity对象 堆配置文件说有一个IntroActivity实例和4个实例是IntroActivity的内部类 内部课程如下，包括匿名课程。
