Question

我的应用程序在playstore中有一个错误。它仅在OREO设备中发生。跟踪在下面。您能帮我找到原因吗？

D:\Trabalhos\Mobile\node\cordova>cordova -v
8.0.0

D:\Trabalhos\Mobile\node\cordova>node -v
v10.10.0

顺便说一句，我有一个下面的方法。它返回已安装应用程序的列表。列表的元素是“ MainActivity_App”。在方法中，首先，我一个接一个地获取应用程序的图标，程序包名称和名称，然后使用它们创建MainActivity_App。该代码可能会发生错误吗？

Answer 1

我找到了此异常的原因。然后，我为该异常提出了解决方案。

原因：加载图标时，可以返回在OREO和更高版本中可绘制的位图。因此，如果您使用；

   imageView.setBackground(info.loadIcon(getPackageManager());

当info.loadIcon（）方法返回bitmapDrawable时，您将获得java.lang.IllegalArgumentException。您可以使用以下方法来解决此问题。

   X = info.loadIcon(getPackageManager();
   if (X instanceOf Bitmap)
       imageView_appIcon.setImageBitmap(X);
   else
       imageView_appIcon.setBackground(X);

希望，它会有所帮助。
