Android gives error “Cannot fit requested classes in a single dex file”

Question

I don\'t know why but it\'s impossible to launch my app on my mobile this morning. I get this error message:

Cannot fit requested classes in a single dex

Answer 1

Running RN 0.62 and this worked for me with successful build.

Update build.gradle

classpath('com.android.support:multidex:1.0.3')

Update defaultConfig

multiDexEnabled true

After those 2 changes, restart the gradle build again.
