You need to follow below points while working with react native application, this ultimately solve your issue.

1. Make use Component hierarchy should be maintain, for example all components like Text, ListView, TextInput etc should be wrapped inside the parent component that is View. 
lets see the below example : 
<View>
    <Text>
       CORRECT
    </Text>
</View>

2. Make sure all the Component tag should be closed properly.

3. Make sure unnecessary semicolons should be removed from the react native layout components & functions.
