Hi, We received VAR-DVK-MX6 capacitive (with quadcore) but it doesn't want to finish boot process of Android 6.0.1. Sometimes freezes on bootanim, sometimes reboots during bootanim. Keymaster v1.0 key blobs are wrapped inside keystore blobs, which are in turn stored as files in /data/misc/keystore/userX, as before (where X is the Android user ID, starting with 0 for the primary user). Keymaster blobs are variable size and employ a tag-length-value (TLV) format internally.
I’m trying to run AwesomeProject on my Nexus5 (android 5.1.1).
I’m able to build the project and install it on the device. But when I run it, I got a red screen saying
Unable to download JS bundle. Did you forget to start the development server or connect your device?
In react native iOS, I can choose to load jsbundle offline. How can I do the same thing for Android? (Or at least, where can I configure the server address?)
Update
To run with local server, run the following commands under your react-native project root directory
- react-native start > /dev/null 2>&1 &
- adb reverse tcp:8081 tcp:8081
please take a look at dsissitka’s answer for more details.
To run without a server, bundle the jsfile into the apk by running:
- create an assets folder under
android/app/src/main
curl 'http://localhost:8081/index.android.bundle?platform=android' -o 'android/app/src/main/assets/index.android.bundle'
please take a look at kzzzf’s answer for more details.

Update 2: @scgough We got this error because React Native (RN) was unable to fetch JavaScript from the dev server running on our workstations. You can see why this happens here:
If your RN app detects that you’re using Genymotion or the emulator it tries to fetch the JavaScript from GENYMOTION_LOCALHOST (10.0.3.2) or EMULATOR_LOCALHOST (10.0.2.2).
Otherwise it presumes that you’re using a device and it tries to fetch the JavaScript from DEVICE_LOCALHOST (localhost).
The problem is that the dev server runs on your workstation’s localhost, not the device’s, so in order to get it to work you need to either:

Ok, I think I’ve figured what the issue is here. It was to do with the version of
watchman
I was running.In a new shell, run
then:
then:
brew update
then:
brew unlink watchman
then:
brew install watchman
now, you can run
react-native start
from your project folderI leave this shell open, create a new shell window and run:
react-native run-android
from my project folder. All is right with the world. ps. I was originally on version 3.2 of watchman. This upgraded me to 3.7.
pps. I’m new to this so that might not be the swiftest route to the solution but it has worked for me.

Delete the App from your phone! I tried several steps, but that did it eventually.
- If you tried to run your app before but failed, delete it from your android device.
- Run
$ react-native run-android
- Open the React Rage Shake Menu from within your app on your android device, go to
Dev Settings
and then toDebug server host & port for device
. There enter your server IP (IP of your computer) and host8081
, e.g.192.168.50.35:8081

I was getting this on Linux after stopping down the
react-native run-android
process. Seems the node server is still running so the next time you run it, it won’t run properly and your app can’t connect. The fix here is to kill the node process which is running in an Xterm which you can kill by
ctrl-c
ing that window (easier) or you can find it using lsof -n -i4TCP:8081
then kill -9 PID
. Then run
react-native run-android
again. Answers:
Check your wifi connection.
Another possibility could be you are either not connected to wifi, connected to the wrong network, or the ip address is wrong in your dev settings. For some reason, my android disconnected from the wifi and I started to get this error, unknowingly.

I have found another answer.
- adb reverse: only work on Android 5.0+ (API 21).

An update
Now on windows no need to run react-native start. The packager will run automatically.
Answers:
Here are the simple steps to run your app on android(release):
1. Go to your application root.
2. Run this command.
react-native bundle –platform android –dev false –entry-file
index.android.js –bundle-output
android/app/src/main/assets/index.android.bundle –assets-dest
android/app/src/main/res
index.android.js –bundle-output
android/app/src/main/assets/index.android.bundle –assets-dest
android/app/src/main/res
All your files are copied.
3. Create signed APK.
Open android studio.
Build > Generate Signed APK > [Fill required details, keystroke has to be generated before this step]
Your APK should be generated without any errors. Install on your device and this should work without any issues.
You can also connect your device and directly hit Run icon on android studio for testing.
Generating Keystroke:
- Goto C:Program FilesJavajdkx.x.x_xbin
- Run
keytool -genkey -v -keystore d:my_private_key.keystore -alias
my-key-alias -keyalg RSA -keysize 2048 -validity 10000
my-key-alias -keyalg RSA -keysize 2048 -validity 10000
Nov 25, 2016 It took really a long time and I was running out of time and losing my patience. The GPG isn’t generated even after I waited for almost an hour. I am not aware of GPG key generation process at that time, and I have never created one before. So I dig a little in Google and found out that I need to generate enough Entropy for GPG key. Trying to generate a key for a server. Gpg -gen-key We need to generate a lot of random bytes. It is a good idea to perform some other action (type on the keyboard, move the mouse, utilize. Feb 28, 2016 gpg-keygen. A readme and a script to generate PGP keys using GnuPG, using the current best practices. Its goal is to provide a concise and up-to-date description of best practices regarding the usage of GnuPG. Gpg generate key long time free.
It will probably ask you to fill in some details. Do it and your have your keystroke file(my_private_key.keystore) which can be used to sign your apk.

The initial question was about reloading the application in a phyisical device.
When you’re debugging the application in a physical device (ie via adb), you can reload the JS bundle by clicking on the top left “action” button of your device. This will open the option menu (Reload, Debug JS remotely…).
Hope this helps.

You can follow the instruction mentioned on the official page to fix this issue. This issue occur on real device because the JS bundle is located on your development system and the app inside your real device is not aware of it’s location.
