Android强制关闭imageview

Question

In folder res/drawable/ I have stored my image pic.jpg, but the application force closes when I run it on my device. The android project was automatically generated, except I have changed the RelativeLayout that encloses everything to a LinearLayout. Inside of this LinearLayout I have only coded a single ImageView. The application force closes without displaying anything. Please, what am I doing wrong?

Relevant XML:

<ImageView
    android:layout_width="85dp"
    android:layout_height="85dp"
    android:src="@+drawable/pic"
    android:contentDescription="@string/none" 
/>

Here is the logcat:

Answer 1

android:src="@+drawable/pic"

should be without a + sign. Accessing /res/drawable resources is constant - they can't be dynamically generated so having a + shouldn't work.

android:src="@drawable/pic"

Also make sure that your pic picture file is copied into the drawable folder. Linking from the filesystem is not the same since the file is not actually in the folder. Linking will result in a no resource found that matches the given name error.
