Can you provide more details?

For instance, using adb logcat, you can see more logs, and about the same time it crashes there should be some error in the log related to Node.js Mobile.

@Priyanshu-psiborg As the error says, it cannot find main.js, which is the entry point for your Node.js subprogram inside the mobile app. You may have done or moved the main.js somewhere such that nodejs-mobile-react-native cannot find it (thus cannot move it into the mobile app). Have you renamed sample-main.js to main.js?

[Priyanshu-psiborg]

Yes It was renamed when i tried reinstalling the module .
Another thing, do we need to create whole build every time after every change ?
