你有NullPointerException在线169。不知道是什么行是...

我们知道你的代码块是：

Uri selectimage=intent.getData(); 
Log.d("take","pic"); 
img1.setImageURI(selectimage); 

因为你ResultInfo显示request=2, result=-1。这意味着你的空指针在那里。

最可能的原因是img1为空。我看到你在上面使用它，但是它在后面的范围内是未知的。不知道如何或何时初始化，很难说。

这里没有太多可以发生的事情。唯一的另一种可能性是intent为空，但我不算太多。你的ResultInfo清楚地显示回来的意图。

未来，您可以自己在logcat中找到这些东西。只要寻找类似：

Caused by: java.lang.NullPointerException 
    at com.inspectreport6784.NewInspection.onActivityResult(NewInspection.java:169) 

对于简单的空指针，它很容易缩小。它为您提供文件，类，方法和行。
