Solutions to Android custom Fonts

About Android custom Fonts
I used the following statement to customize the font of the content:

Textview TV = (textview) findviewbyid (R. Id. maintitle );
// Change the font
Typeface face = typeface. createfromasset (getassets (), "fonts/hyyy. TTF ");
TV. settypeface (FACE );

Import the font file hyyy. TTF in assets/front. The size is 3.37 MB.

But the program does not know why it cannot run.
The following figure shows the logcat:

How can I modify it?

------ Solution --------------------------------------------------------
There is no problem with the Code. 3 m + is too big. Use fontcreator to crop it, several hundred K.
I guess this is probably because native typeface cannot be made.

The file format is defined as MP3 or zip, so there is no size limit, so it is still used in use, you try
