Same issue here. Do you have an update?

[UnleashedMind]

Did you try to use the solution by nara posted in #172?

[balwinder4264]

i was facing this issue because i instaall package image slider having react-native in it try to unlink plugin when you start facing this issue.

@UnleashedMind I tried #172 and it did not help me as it requires the following code to run react-native run-android --config=rn-cli.config.js while --config is not a part of the CLI. Do you have any suggestions?

After publishing this. I did the below setup and it worked.

1. I created a file name rn-cli.config.js
2. I then open the file and add ``` module.exports = { resolver: { blacklistRE: /#current-cloud-backend/.*/ } };

This is the same setup that other developers mention in issue #172 
3. I relaunch my Android Studio and run my Virtual Phone.
4. I run ``` react-native start --config=rn-cli.config.js --resetCache ``` and like Magic, my app was working. 
5. I am still to figure out how to get this to work with ``` react-native run-android ``` I'm open for suggestions. 


The issue is resolved for me. Thank you all for your help.
