I met this problem after load JS, any idea for this ? many thanks.
TypeError: expected dynamic type 'string', but had type 'int64'.
The error is caused by react-native using the gradle package on the repository which is pre-built. If your version of react-native is from github then you are most likely to run into incompatible binaries.
Solution is to change the file in ProjectName/android/app/build.gradle
compile 'com.facebook.react:react-native:0.11.+'
to
compile project(':ReactAndroid')
That way it will depend on your local library (and ofcourse you need to move the ReactAndroid folder to its correct position & you will need the android-ndk )
I would strongly recommend to wait for sometime.
