Attempt to Invoke Interface Method 'boolean com.facebook.react.brige.ReadableMap.hasKey(java.lang.String)' on a null object reference

See original GitHub issue

My code works fine on iOS, the trouble begins in Android. Whatever I do, I face this error: screen shot 2017-11-16 at 17 37 08

This is how I invoke image picker:

uploadFile() {
		ImagePicker.launchImageLibrary(null, (response)  => {
			console.log('Response = ', response);

Solution

You shouldn’t set option to null as it will cause the error. You better use an empty object {} instead. Adding some robustness can help other developers not to encounter this error.

react-native-cli: 2.0.1 react-native: 0.46.3 react-native-image-picker 0.26.7 Android MacOS
