我使用LeakCanary来检测我的应用程序中的内存泄漏。我的代码有什么问题，为什么会出现这种情况？一开始，我将fragment管理器引用为一个新对象，然后我尝试使用getSupportFragmentManager()，但是还是出现了相同的情况。
以下是日志：
```
ApplicationLeak(className=com.dev.myApp.ViewDialog, leakTrace=

├─ android.app.ActivityThread
│ Leaking: NO (ActivityThread↓ is not leaking and a class is never leaking)

以下是Java代码
ViewDialog dialog;
public void showMyDialog(int position, String type){
Bundle bundle = new Bundle();
bundle.putInt(CONST.POSITION, position);
bundle.putString(CONST.TYPE, type);
dialog = new ViewDialog();
dialog.setArguments(bundle);
dialog.show(getSupportFragmentManager(), "apps_list");
}
public void hideDialog(){
if (dialog != null) {
dialog.dismiss();
}
}
