I've developed an application using Eclipse and when I run it on my Droid Ultra the application runs when running through Eclipse. To my understanding when that happens the application should be installed on the device. However, when I unplug the device and try to run the app by going through my phone applications it displays a toast message saying "App isn't installed". Does anyone know why this is happening? Is this a code problem, an environment issue, anything?
Here is my manifest if it helps?

Do you already have the app installed previously on the device?If so please uninstall the existing app and try again with eclipse.The problem may be due to incorrectly signed certificates.

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?

It is a simple structure in the app. LoginActivity as Start-Activity and a TabbedActivity for the NFC-Stuff.
here is the project I got from my tutor, I got the error after running it on my test phone. I tried the answers on stackovetflow but nothing helps. The logcat and manifest.xml are as follows

try to change your
android:name=".MainActivity"
to fully specified name
android:name="com.imagerecognition.MainActivity"
sometime eclipse act weird.
if it does not work you can try this
unable to find activity
This following method worked for me. Right click on your project and select properties. The "Properties for " panel will open. From the menu on the left go to Java Build Path -> Order and Export . From the list below uncheck the box next to Android Dependencies. Finally clean your project and run.

Try removing the imports and importing them manually again.
Have a problem with an already-published application on Google Play.
The application is in the store, but no one can download, because of an error Supported devices 0.
I did refactor the project, removed all unnecessary with the manifest. Compiled a new apk, and again "Supported devices 0".
I use pdfbox-android-1.8.8.jar.
If I remove the pdfbox from project, then are "Supported devices 7700".
I build project with Eclipse.
What does this mean?

I have copied my Manifest XML File. I am just not able to figure out the error. The application is running on my Redmi 1S but it is not running on my Micromax Canvas A110 I have already tried all the solutions which are already there on Stackoverflow related to this.

clean your project and if it doesn't work than close
the project and restart, create new apk and install
This error is come due to different android version of your both android phones.
Please check the configuration for both the phones and change according to that in manifest.xml file
android:minSdkVersion="11"
android:targetSdkVersion="19"
Thanks

You can't.
Third party developers cannot set their own app as default applications. Only the users of your app can do this on their own devices.
You can however, register to receive intents of the types your app supports so that users can select your app as their default. For example, to register your app as a music player, see here.
This is impossible. this can not be done using code . if one application need to set as default it must do by the user.not thrid party
