How to add custom font in react native android

Question

I want to set fontFamily to roboto thin of my toolbar title.

I have added roboto thin ttf in assets/fonts folder of my android project, however it seems that it is creating issues while running app. I am getting this issue while running

react-native start

ERROR  EPERM: operation not permitted, lstat 'E:\Myntra\android\app\build\gener ated\source\r\debug\android\support\v7\appcompat' {"errno":-4048,"code":"EPERM","syscall":"lstat","path":"E:\\Myntra\\android\\app \\build\\generated\\source\\r\\debug\\android\\support\\v7\\appcompat"} Error: EPERM: operation not permitted, lstat 'E:\Myntra\android\app\build\genera ted\source\r\debug\android\support\v7\appcompat'     at Error (native) 

When I am removing the font then it is working fine. I am unable to fix this issue. What's the reason?

Answer 1

1. Add your fonts file in

   • Project folder/android/app/src/main/assets/fonts/font_name.ttf
2. Restart the package manager using react-native run-android
3. Then you can use your font in your style e.g
   • fontFamily: 'font_name'

UPDATE

Many answers are here for adding custom font in react-native for version < 0.60.

For those who are using react-native version > 0.60 , 'rnpm' is deprecated and custom fonts will not work.

Now, in order to add custom font in react-native version > 0.60 you will have to :

1- Create a file named react-native.config.js in the root folder of your project.

2- add this in that new file

module.exports = { project: {     ios: {},     android: {}, }, assets: ['./assets/fonts'] }; 

3- run react-native link command in the root project path.

PS Make sure you have the right path for the fonts folder before running react-native link command
