Look at the Manifest

<uses-sdk android:minSdkVersion="16" />

Your Device is 15.

About the message Unable to find unity activity in manifest., try adding the following line inside the <activity> tag in AndroidManifest.xml (found in Assets/Plugins/Android):

<meta-data android:name="unityplayer.UnityActivity" android:value="true" />
