How to add manifest permission to an application?

Permission name is CASE-SENSITIVE

In case somebody will struggle with same issue, it is case sensitive statement, so wrong case means your application won't get the permission.

WRONG

<uses-permission android:name="ANDROID.PERMISSION.INTERNET" />

CORRECT

<uses-permission android:name="android.permission.INTERNET" />

This issue may happen ie. on autocomplete in IDE

Assuming you do not have permissions set from your LogCat error description, here is my contents for my AndroidManifest.xml file that has access to the internet:

<manifest xlmns:android...>
 ...
 <uses-permission android:name="android.permission.INTERNET" />
 <application ...
</manifest>

Other than that, you should be fine to download a file from the internet.
