Android App ist running on Device in USB-Debug-Mode but not after APK-Install

I am very new In Android Development and developed a "Time Stamp Clock - App" which reads NFC-Tags.
Everything fine, it is running on Device via USB-Debug-Mode without Errors as expected. When I build APK and install on the same Device, the installing is without errors, but after that, the open-button is grayed out and inactive and there is no desktop-icon to launch. In the APPS Overview it is displayed, but not able to open.
Can someone tell me, what can i do, to figure it out, what is going wrong there?
EDIT:

It is a simple structure in the app. LoginActivity as Start-Activity and a TabbedActivity for the NFC-Stuff.

Tag <uses-permission> attribute name has invalid character ' '

I am getting an error in manifest continiously.
Tried a lot but unable to fix it.

My efforts:
I tried to remove error by myself but failed again and again !
Searched on google ....searched all possible links for it.
Any help wil be appreciated ! Thanks in advance :)
..
Problem is with debug/AndroidManifest.xml.

My suspicion is that it has to do with the com.google.android.providers.gsf.permission.READ_GSERVICES permission. The newer documentation does not show that it's a requirement for location stuff: https://developers.google.com/maps/documentation/android-api/location
I was able to solve this issue by taking out all of the permissions and adding them one by one, rebuilding the project each time I added a permission back. The permission that gave me an issue, caused the error. Good luck :)

logcat report of push not being enabled correclty

I'm using Parse as a back end for my app and I used their quick start guide to setup push notifications.
I've followed it step by step and do not get pushes. Also I get this report in logcat when I start the app
08-22 18:46:34.785 4325-4325/maxbleggi.afstudentplanner D/com.parse.ParsePushChannelsController﹕ Tried to subscribe or unsubscribe from a channel, but push is not enabled correctly. Push is not configured for this app because the app manifest is missing required declarations. Please add the following declarations to your app manifest to use GCM for push: make sure that these permissions are declared as children of the root <manifest> element:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />

<permission android:name="maxbleggi.afstudentplanner.permission.C2D_MESSAGE" android:protectionLevel="signature" />
<uses-permission android:name="maxbleggi.afstudentplanner.permission.C2D_MESSAGE" />
Also, please make sure that these services and broadcast receivers are declared as children of the <application> element:

here is where I start parse
...
Parse.setLogLevel(Parse.LOG_LEVEL_DEBUG);
ParseInstallation.getCurrentInstallation().saveInBackground();
ParsePush.subscribeInBackground("", new SaveCallback()
{
#Override
public void done(ParseException e)
{
if (e == null)
{
} else
{
}
}
});
When I use my device I do not receive this logcat report but I do receive it when I use an emulator

If using Genymotion as emulator and it does not have Google Apps installed on it, that might cause the issue. Try to Install ARM translation and check again. For more see Unable to get push notification when using Genymotion as my emulator of my android app

I know there could be complex emulator problems but picking a simple one you seem to be missing a permission
<uses-permission android:name="maxbleggi.afstudentplanner.permission.C2D_MESSAGE" />

You application 'disappeared' because you commented these lines at SplashActivity section:
<!--
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
-->
as for share provider, which part are you stuck at?
