I have given app_name as below :
<string name="app_name">My \'App</string>
to use apostrophe I used \ in it.
But, still it giving me below error:
Error:(2) Apostrophe not preceded by \ (in My 'App)
So, I removed ' from the app_name and write it as simply My App. But, still it giving me same error, I have restarted android studio, cleaned project and even restarted my system but,still getting same error.
Replace your line
<string name="app_name">My \'App</string>
with
<string name="app_name">My 'App</string>
