Install Via USB not working - The device is temporarily restricted

I was trying to install apk via USB but I was not able to install it. I was getting problem while enabling the 'Install via USB' in settings of mobile in Red MI 4 phone.

Error:


1. the device is temporarily restricted 3-3 in mobile

2. When I was runing react-native app:

What went wrong:
Execution failed for task ':app:installDebug'.

> com.android.builder.testing.api.DeviceException: com.android.ddmlib.InstallException: Failed to finalize session : INSTALL_FAILED_USER_RESTRICTED: Install canceled by user

Solutions:


1. After searching on internet, I found couple of options but it not worked.
Disable WIFI and enable mobile network

2. Finally, I installed VPNFlex app from google play store and selected CHINA-SHANGHAI in the app.

Now, I enabled 'Install via USB' option from settings and it is working without any error.

unable to load scripts from assets 'index.android.bundle' on real device

When I was runing below run-android then, I was getting unable to load script from asset error on emulator as shown below:

sachin@sachin-E470:~/react-native/test1$ react-native run-android

Then, I ran below commands,

sachin@sachin-E470:~/react-native/test1$ mkdir android/app/src/main/assets

sachin@sachin-E470:~/react-native/test1$ 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

sachin@sachin-E470:~/react-native/test1$ react-native run-android

Below is the result screenshot.

But, Now problem is, when I am changing App.js, changes are not reflecting in emulator device.
Any help for the same???
