Eclipse LogCat error associated with custom font

Question

When I launch my app I get the message "Unfortunately [app name] has stopped" on my emulator.

According to my LogCat, the problem is caused by an error on line 19.

Line 19 in MainActivity.java is part of my custom text view code.

If I completely delete my custom text view code in MainActivity.java and the associated TextView in activity_main.xml I do not get the error. Therefore, I have pinpointed that this custom text view seems to be the root of the problem.

I have tried the following troubleshooting:

• ensuring the .ttf font file is written in lower case
• ensuring the .ttf font file is actually a .tff file
• storing the .ttf font file under assets
• storing the .ttf font file under fonts subfolder in assets

I have actually been on this simple issue for days. I have read numerous threads that address what seems to be my same problem, but no simple fix seems to work.

Cheers in advance for your help

Font file is located under assets/fonts/quicksandlight.ttf

Answer 1

setContentView(R.layout.splash);

But your textview is in activity_main.xml

This

txt.setTypeface(font); 

will give you NUllPointeException

Should be

setContentView(R.layout.activity_main);

findViewById looks for a view with the id in the current infalted layout.

Answer 2

you are using wrong layout file in your activity, that is why your TextView txt is null, change setContentView(R.layout.splash); to setContentView(R.layout.activity_main);
