Modifying the "build.gradle"
On android, you can modify the "build.gradle" file inside /android/app/build.gradle.
Remember, it is NOT the file in /android/app/gradle/build.gradle.
then, go to the sited file and search for:
def jscFlavor = 'org.webkit:android-jsc:+'
then replace like this
//def jscFlavor = 'org.webkit:android-jsc:+'
def jscFlavor = 'org.webkit:android-jsc-intl:+'
you should comment this line both are not equal
