Problem

When using fetch to make a get to an external api, and if debugging in chrome is active, then it never reaches the second "then" until there is an interaction with the UI, such as a tap on the screen, but if debugging is turned off then this problem goes away. [code block] Using React Native 0.22 Only occurs on Android (both Genymotion and on device (5.0)) Using a Mac

react-native-cli: 0.2.0
react-native: 0.22.2

Quick workaround is to add empty timeout execution:

``` javascript
fetch('http://example.com')
    .then(response => {
        setTimeout(() => null, 0);
        return response.text();
    })
    .then(response => {
        console.log(response);
    });
