Can't load any external fonts in android studio

Update:
I created an asset folder and inside of it is a century.ttf file. First I got a wrong encoding problem but after I followed these steps after File was loaded in the wrong encoding 'UTF-8' while pasting new font to Assets Folder in Android Studio the error message disappeared.
Then I wrote into my MainActivity:
FOURTH UPDATE:
Typeface typeface = Typeface.createFromAsset(getAssets(),"century.ttf");
Text.setTypeface(typrface);
But then my app suddenly stops.

FOURTH UPDATE:

Follow the instructions in the link below and go to the manifest file and add android:name="the-below-implementation" under application xml tag
https://github.com/chrisjenx/Calligraphy

Considering you use ttf fonts in asset folder, generate typeface like this.
Typeface typeface = Typeface.createFromAsset(getAssets(),"YourFontName.ttf");
Text.setTypeface(typrface);

Your code is requesting font/century (see: Caused by: java.lang.RuntimeException: Font asset not found font/century). The actual asset is font/century.tff (according to your comment), or possibly font/century.ttf (which would be the more likely file extension for TrueType fonts).
The font path you provide needs to match the actual path in assets/, including file extensions.

Try putting the ttf file into a "fonts" folder inside the "Assets" folder and then change the source path "fonts/century.ttf". My guess is that the file isn't being recognized as a font file.
This is how I have it set-up in one of my projects:

Android didn't find application class crash

In Manifest I declared
<application
android:name=com.example.App>
When the app starts, sometimes this crash happens:
java.lang.RuntimeException: Unable to instantiate application com.example.App: java.lang.ClassNotFoundException: Didn't find class "com.example.App" on path: DexPathList[[zip file "/mnt/asec/com.example.myapp-1/pkg.apk"],nativeLibraryDirectories=[/mnt/asec/com.example.myapp-1/lib, /vendor/lib, /system/lib]]

Is it possible to fix it somehow?

This doesn't seems to be an app crash. This is just a verbose message raised when dalvik reinstall the apk.It won't occur on end-user's device.To fix it on your development machine, just clean and rebuild.

Usually the app stops working if your code contains errors.
Are there errors in your code? What does the LogCat say?

The database only shows 1 active connection, so I know it is not because of too many open connections. I have tried rebooting the server, but it didn't help. I am using the MySQL JDBC Connector/J version 5.1.23. The phone that works is running Android version 2.3.5 and the one that doesn't work is running Android version 4.0.4. Does anyone have any ideas as to what might be wrong?
Thanks!

You can't do network IO on the main thread. Move it to an AsyncTask or thread.
