Downgrading to react-native 0.48.4 solved the problem. Still not an optimal solution, so I won't mark this as the answer.

_# ###SOLUTION

react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res 

OUTPUT will be :
c:\Users\lenger\Desktop\webrowser>react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res
Scanning folders for symlinks in c:\Users\lenger\Desktop\webrowser\node_modules (43ms)
Scanning folders for symlinks in c:\Users\lenger\Desktop\webrowser\node_modules (38ms)
Loading dependency graph, done.
bundle: start
bundle: finish
bundle: Writing bundle output to: android/app/src/main/assets/index.android.bundle
bundle: Done writing bundle output

and after 

Run react-native run-android again, you will find your modification work.

Try,

<pre><code>rm -rf /usr/local/var/run/watchman &amp;&amp; npm uninstall watchman &amp;&amp; npm install watchman
</code></pre>

or

<pre><code>rm -rf /usr/local/var/run/watchman &amp;&amp; brew uninstall watchman &amp;&amp; brew install watchman
</code></pre>

Then

<pre><code>react-native run-android
</code></pre>

I have a react native app, right now when I make changes to it hot-reloading is triggered but the changes do not show up in the app. E.g. changing a background color from green to white in a stylesheet causes app to say "Hot Reloading" but then the color stays white. Fully reloading the app will then show the green background. 

Things I have tried:

<a href="https://github.com/react-community/create-react-native-app/issues/88" rel="nofollow noreferrer">Setting root component to a class.</a> 

<a href="https://github.com/facebook/react-native/issues/10889" rel="nofollow noreferrer">Removing yarn.lock</a> 

<a href="https://github.com/facebook/react-native/issues/10889" rel="nofollow noreferrer">Reinstalling watchman</a>

<a href="https://github.com/bvic23/babel-plugin-functional-hmr" rel="nofollow noreferrer">Installing Babel Functional HMR</a>

Running simulator via Xcode and <code>react-native run-ios</code>.

Running with only hot-reload, both hot-reload and live-reload, only live-reload. With and without remote-debugging.

System: 
MacOS: 10.13.2 
React-Native: 0.51.0 
React-Native-Cli: 2.0.1 
Xcode (for running the simulator): 9.2

What is going wrong here? How can I get hot-reloading to work? 

EDIT:

Looks like this is an <a href="https://github.com/facebook/react-native/issues/16505" rel="nofollow noreferrer">bug</a>. Keeping this question open incase someone has a workaround.

我有一个反应本机应用程序，现在，当我对它进行更改-热重加载被触发，但变化没有显示在应用程序。例如，在样式表中将背景颜色从绿色更改为白色，会导致应用程序说“热重加载”，但随后颜色将保持白色。完全重新加载，然后应用程序将显示绿色背景。我尝试过的事情： (由于解决方案过时而无法工作)通过Xcode和react-native ...
