java.lang.RuntimeException：将结果ResultInfo {who = null,request = 1,result = -1,data = intent}传递给活动失败

在我的应用程序中,我点击了一个名为Pick Photo的按钮,它加载了图库.当我单击图库中的图像时,应用程序强制关闭,在我的logcat中,我收到以下内容：

    java.lang.RuntimeException: Failure delivering result ResultInfo{who=null,request=1,result=-1,data=Intent { dat=content://media/external/images/media/3369 (has extras) }} to activity {cap.shot/cap.shot.LolcatActivity}: java.lang.NullPointerException

最佳答案

getDrawable在你的情况下返回null.
您用于setimageURI的uri可能无效,因此您将获得null.

对drawable执行null检查,如果drawable为null,则需要保释.

编辑：

if(drawable == null)
  return;
