React-native: [JS] Automatically run `adb reverse tcp:8081 tcp:8081` when starting packager

[mkonicek]

This would make developing on a device easier:

@mkonicek That is a great idea and would definitely make it easier to develop on a physical device!

Note that you can easily add npm scripts to make your team's life easier.
For instance, in your package.json under scripts you can add something like this :

"android-dev": "adb reverse tcp:8081 tcp:8081 && react-native run-android"

Then you can simply run npm run android-dev and you're all set.

Added in https://github.com/facebook/react-native/pull/8345 🎉

Well done @burgalon! 💯

@mkonicek Hi! am trying to run the application in android 4.2.2(JB) physical device, am facing the exact same problem. But adb reverse won't work, can you please help me find solution for this. Thanks in advance.

Please tap on android simulator and Try F10 it works for me..

adb reverse was not working for me too for some strange reason after updating my one plus 3 device,
i used ngrok as a tunnel to port 8081 and changed the 'server address' under 'dev settings' in debug menu of app to point to ngrok url.

@kamek-pf when i run react-native* run-android* in ubuntu i'm getting the following error:

This build could be faster, please consider using the Gradle Daemon: https://docs.gradle.org/2.14.1/userguide/gradle_daemon.html
Running adb -s e0e3d69d reverse tcp:8081 tcp:8081
Android Debug Bridge version 1.0.31
-a - directs adb to listen on all interfaces for a connection
-d - directs command to the only connected USB device
returns an error if more than one USB device is present.
-e - directs command to the only running emulator.
returns an error if more than one emulator is running.
-s - directs command to the device or emulator with the given
serial number or qualifier. Overrides ANDROID_SERIAL
environment variable.
-p - simple product name like 'sooner', or
a relative/absolute path to a product
out directory like 'out/target/product/sooner'.
If -p is not specified, the ANDROID_PRODUCT_OUT
environment variable is used, which must
be an absolute path.
-H - Name of adb server host (default: localhost)
-P - Port of adb server (default: 5037)
devices [-l] - list all connected devices
('-l' will also list device qualifiers)
connect [:] - connect to a device via TCP/IP
Port 5555 is used by default if no port number is specified.
disconnect [[:]] - disconnect from a TCP/IP device.
Port 5555 is used by default if no port number is specified.
Using this command with no additional arguments
will disconnect from all connected TCP/IP devices.
device commands:
adb push - copy file/dir to device
adb pull [] - copy file/dir from device
adb sync [ ] - copy host->device only if changed
(-l means list but don't copy)
(see 'adb help all')
adb shell - run remote shell interactively
adb shell - run remote shell command
adb emu - run emulator console command
adb logcat [ ] - View device log
adb forward --list - list all forward socket connections.
the format is a list of lines with the following format:
" " " " "\n"
adb forward - forward socket connections
forward specs are one of:
tcp:
localabstract:
localreserved:
localfilesystem:
dev:
jdwp: (remote only)
adb forward --no-rebind
- same as 'adb forward ' but fails
if is already forwarded
adb forward --remove - remove a specific forward socket connection
adb forward --remove-all - remove all forward socket connections
adb jdwp - list PIDs of processes hosting a JDWP transport
adb install [-l] [-r] [-s] [--algo --key --iv ]
- push this package file to the device and install it
('-l' means forward-lock the app)
('-r' means reinstall the app, keeping its data)
('-s' means install on SD card instead of internal storage)
('--algo', '--key', and '--iv' mean the file is encrypted already)
adb uninstall [-k] - remove this app package from the device
('-k' means keep the data and cache directories)
adb bugreport - return all information from the device
that should be included in a bug report.
adb backup [-f ] [-apk|-noapk] [-shared|-noshared] [-all] [-system|-nosystem] [ - write an archive of the device's data to .
If no -f option is supplied then the data is written
to "backup.ab" in the current directory.
(-apk|-noapk enable/disable backup of the .apks themselves
in the archive; the default is noapk.)
(-shared|-noshared enable/disable backup of the device's
shared storage / SD card contents; the default is noshared.)
(-all means to back up all installed applications)
(-system|-nosystem toggles whether -all automatically includes
system applications; the default is to include system apps)
( the -all or -shared flags are passed, then the package
list is optional. Applications explicitly given on the
command line will be included even if -nosystem would
ordinarily cause them to be omitted.)
adb restore - restore device contents from the backup archive
adb help - show this help message
adb version - show version num
scripting:
adb wait-for-device - block until device is online
adb start-server - ensure that there is a server running
adb kill-server - kill the server if it is running
adb get-state - prints: offline | bootloader | device
adb get-serialno - prints:
adb get-devpath - prints:
adb status-window - continuously print device status for a specified device
adb remount - remounts the /system partition on the device read-write
adb reboot [bootloader|recovery] - reboots the device, optionally into the bootloader or recovery program
adb reboot-bootloader - reboots the device into the bootloader
adb root - restarts the adbd daemon with root permissions
adb usb - restarts the adbd daemon listening on USB
adb tcpip - restarts the adbd daemon listening on TCP on the specified port
networking:
adb ppp [parameters] - Run PPP over USB.
Note: you should not automatically start a PPP connection.
refers to the tty for PPP stream. Eg. dev:/dev/omap_csmi_tty1
[parameters] - Eg. defaultroute debug dump local notty usepeerdns
adb sync notes: adb sync [ ]
can be interpreted in several ways:
- If is not specified, both /system and /data partitions will be updated.
- If it is "system" or "data", only the corresponding partition
is updated.
environmental variables:
ADB_TRACE - Print debug information. A comma separated list of the following values
1 or all, adb, sockets, packets, rwx, usb, sync, sysdeps, transport, jdwp
ANDROID_SERIAL - The serial number to connect to. -s takes priority over this if given.
ANDROID_LOG_TAGS - When used with the logcat option, only these debug tags are printed.
Could not run adb reverse: Command failed: adb -s e0e3d69d reverse tcp:8081 tcp:8081
Starting the app on e0e3d69d (adb -s e0e3d69d shell am start -n com.sample/com.sample.MainActivity)...
Starting: Intent { cmp=com.sample/.MainActivity }

It seems * adb reverse tcp:8081 tcp:8081* command in not working.
