应用程序无法在Android 4.0及更高版本中运行

概述我试图在编辑文本中显示图像和文本,但它不适用于冰淇淋三明治和Jellybean ..  它在以下版本中运行良好. 当活动暂停并再次恢复时,它会在编辑文本中显示图像名称而不是图像以及文本. 请参考图像和相关代码 public class MainActivity extends Activity implements OnClickListener, OnItemClickListe 我试图在编辑文本中显示图像和文本,但它不适用于冰淇淋三明治和Jellybean ..

当活动暂停并再次恢复时,它会在编辑文本中显示图像名称而不是图像以及文本.

请参考图像和相关代码

解决方法 我想我们需要一些追踪才能更好地了解出了什么问题.但是当你无法加载图像时,我想知道是否可能失去了对外部存储目录的访问权限 总结
