Android App reports "not installed" due to permission error
===

On a tablet I installed a apk develloped in Eclipse under Ubuntu. The App works on the AVD and is already installed on a phone and working.
The installation of the apk gives no error, however when starting the App it gives a "not installed" toast message.

In the aLogCat output I see a Permission denial message of the Launcher for WRITE_EXTERNAL_STORAGE. Note that the USB connection is not connected when I started the App.

Furthermore I noticed the following line in aLogCat and I noted that the "-1" was added to the package name.
>        New package installed in /data/app/com.company.AppName-1.apk 

In the manifest the lines 

>        <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
>        <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="15" />

are in the manifest block and
>        <android:permission="android.permission.WRITE_EXTERNAL_STORAGE">

in the application block.

Why is this working on a Android 2.3 phone and in a Android 4.0.3 AVD, but not on a Android 4.0.3 tablet?

Platform info: Eclipse 3.7.2, Tablet: Yarvik TAB461EUK; Installed with "ES File Explorer"
