title: Do I have to declare both WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE?
body: <p>Is it enough to declare <code>&lt;uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /&gt;</code> or do I also have to declare <code>&lt;uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /&gt;</code>?  The Javadocs omit this important information.</p>
