Android Studio Refuses to Connect to React Native Server - android

Hi I'm trying to get the basic React Native tutorial here set up, under the CLI quickstart tab, but I keep running into issues. Please note that I'm trying to run this on an emulator.
Here are the specifics of my set up:
Mac OS: Mojave 10.14.5
Node: 14.15.5
npx: 6.14.11
gem: 3.2.3
watchman: 4.9.0
Android Studio: 3.5.3
JRE: 1.8
Running the command "react-native start" opens up Metro, shows this, but it never says "Done."
Running the command "npx react-native run android" causes this message on the terminal
BUILD SUCCESSFUL in 25s
27 actionable tasks: 5 executed, 22 up-to-date
info Connecting to the development server...
adb: error: cannot bind listener: Operation not permitted
warn Failed to connect to development server using "adb reverse": Command failed: /Users/Library/Android/sdk/platform-tools/adb -s emulator-5554 reverse tcp:8081 tcp:8081
info Starting the app on "emulator-5554"...
Starting: Intent { cmp=com.awesomeproject/.MainActivity }
On the emulator, this is what I see
I've hit the reload button, and gotten this screen on the emulator
then followed instructions detailed here and set up the IP address but still no luck. I've tried using the command "react-native run android" and it gives the same results as above.
This is the most basic project I can set up and I've followed the instructions listed on the tutorial to the letter multiple times with many fresh projects. I'm really not sure what more I can do or where I could've messed up. I've seen similar issues posted on other forums but they've all been closed without proper resolution. I've tried using "adb reverse tcp:8081 tcp:8081" as commonly suggested and it changed nothing.
iOS gives a separate issue entirely but I'll probably make that into a separate question. Does anyone how I can resolve this? What could the issue be here? It seems to be a common enough problem but there's no single agreed solution. Running the app directly in Android Studio results in the same issues too.
I've been trying to make this work for about two weeks now so I appreciate any help people can offer. Thanks.

Error while trying to push/install .apk using adb

I've recently started encountering problems while trying to run my application from Android Studio on my MacOS machine. I tried to run the command from adb myself but I still can't get it to work, although the error appears different.
The errors I get are as follows;
Android Studio
10/02 09:54:53: Launching app $ adb push /Users/{username}/{path-to-apk}.apk /data/local/tmp/{package}
java.io.IOException: Broken pipe
Error while Installing APK
adb (via Terminal.app)
$ adb push /Users/{username}/{path-to-apk}.apk /data/local/tmp/{package}
adb: error: 65536-byte write failed:
Undefined error: 0
Now I've tried a lot of different things, some of which are just stretches because the problem appears to lie in something adb related, but none of this seems to change anything;
Different applications/apks
Different Android devices (total of 5)
Different USB-ports (all 4,
with and without USB-hub).
Different (or no) USB-dongles (USB-C to USB-A)
Restart/Invalidate Caches (Android Studio)
Reinstall Android Studio
Reinstall Android SDK
New (separate) install of Android SDK through homebrew
Reset NVRAM/PRAM
Reset SCM
Update to MacOS Mojave (and retry all of the above).
At this point I am at a loss. Has anyone encountered these errors before without having any of the above solutions fix it? Next thing on my list is a reinstall of the OS, but that feels like a bit of overkill.
I am running on MacOS Mojave on a 2016 Macbook Pro, but everything appeared to have the same effect on High Sierra.
Edit
Weird update on the behaviour, I can get the installing to work continuously after a restart by doing the following steps;
Login
Start Terminal.app
Manually repeat adb push command
(Command executes successfully)
Start Android Studio
Everything works fine...
However, if I start Android Studio without first manually doing the adb push in Terminal, everything is broken as described above.
Edit 2
Even calling adb start-server in Terminal before starting Android Studio makes everything work. So something appears to be faulty when Android Studio is responsible for starting the adb server..
I got the same error. I have no idea but start-server before starting Android-studio
Restart adb with the following command,
adb kill-server && adb start-server
Not really an answer but my issue appears to be solved with the latest release of Android Studio.

Visual Studio Code IDE returns error when attempt to debug React Native project: Could not find device with the id: "simulator"

My environment.
Windows 10 with Android SDK and AVD Manager and VS Code 1.26.1
Android Nexus S simulator with SDK API 23 Android 6.0 x86_64
react-native: 0.55.4
Problem:
I am failing to debug my sample app.js in Visual Studio Code IDE and fail to stop at any breakpoint.
I have AVD emulator running and when I simply run my simple project, the simulator loads it without issues. So, I do not see a problem with my project.
I also can execute “react-native run-android” in Terminal window of VS Code IDE and it returns success, for example:
BUILD SUCCESSFUL Total time: 10.283 secs Running
C:\Users\myusername\AppData\Local\Android\Sdk/platform-tools/adb -s
emulator-5554 reverse tcp:8081 tcp:8081 Starting the app on

emulator-5554 shell am start -n
com.vscodereactdebug3/com.vscodereactdebug3.MainActivity)... Starting:
Intent { cmp=com.vscodereactdebug3/.MainActivity }
However, when I attempt to debug it through Visual Studio IDE (Debug/Start Debugging), the Debug Console shows the following:
OS: win32 x64 Adapter node: v8.9.3 x64 vscode-chrome-debug-core: 3.17.3 Could not debug. Unknown error: not all success patterns were matched. It means that "react-native run-android" command failed.
Please, check the View -> Toggle Output -> React Native, View ->
Toggle Output -> React Native: Run android output windows.
So, below is output from React Native: Run Android:
[Warning] Target simulator is not supported for Android platform. If you want to use particular device or simulator for launching Android
app, please specify device id (as in 'adb devices' output)
instead. [Info] local.properties file doesn't exist. Using

e:\Software\Android\VSCodeReactDebug3\node_modules (20ms) Could not
find device with the id: "simulator". Choose one of the
following: [ 'emulator-5554' ]
I searched forums for the greater wisdom and saw a few posts related to this erratic behavior but those, while sharing good troubleshooting clues, did not solve my problem:
https://github.com/Microsoft/vscode-react-native/issues/624
My project is very simple, almost empty few liners. So, very likely the problem is with my environment, but I cannot find anything that could explain it. I do not recall assigning ID “simulator” to anything. And do not know where it is controlled.
Any ideas are greatly appreciated.
Update.
Today I came across of post React Native debug with Visual Studio Code not working
and attempted uninstalling react-native package and installing react-native-cli. I literally ran following commands in that sequence to use create-react-native-app:
npm install react-native --global
npm uninstall -g react-native
npm install -g react-native-cli
So, now the IDE debugs and stops on breakpoints as before.
I am yet to learn what happened and why my other project suddenly stopped being debugged. I, perhaps, broke my environment attempting to recover from some other problem.
And I still cannot explain the error related to "Could not find device with the id: "simulator"" in the Debug output.

Can't get React Native to work on Ubuntu

I am trying to get React Native running on Ubuntu 16.04. I have used it with create-react-native-app and expo on my Windows machine with both the Android Studio virtual device and a tablet connected by USB. Now I have a new Ubuntu laptop and a Ubuntu dual boot on my PC and am trying to set it up there but have failed miserably.
Let's deal with the laptop. Following the instructions, I have installed Expo and Genymotion. Expo could never work right so now I'm just trying to get it going more directly. I have also installed Java 8 and watchman. I've installed and tried too many things to mention. I've put in about 20 hours so far.
Here is what happens when I try to start things.
If I plug in my tablet, I get:
kevin#kevin-Kudu:~/programming/rn4$ adb devices
adb server is out of date. killing...
* daemon started successfully *
List of devices attached
5205132d4f9011af device
(As a side note, it seems that my adb server is always out of date.) When I try to run the default code installed by react-native-cli by running react-native run-android, I get:
kevin#kevin-Kudu:~/programming/rn4$ react-native run-android
Scanning folders for symlinks in /home/kevin/programming/rn4/node_modules (9ms)
Starting JS server...
Building and installing the app on the device (cd android && ./gradlew installDebug)...
Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object
Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:
https://facebook.github.io/react-native/docs/getting-started.html
I've researched these errors and can't find a solution that works.
If I start an Android Studio virtual device (N6, API 23), it starts up. adb devices gets me:
kevin#kevin-Kudu:~/programming/rn4$ adb devices
adb server is out of date. killing...
* daemon started successfully *
List of devices attached
5205132d4f9011af device

Building and installing the app on the device (cd android && ./gradlew installDebug)...

Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:
https://facebook.github.io/react-native/docs/getting-started.html
Again, I haven't been apple to find a solution.
When I try to do the same thing through genymotion and do adb devices, I get:
kevin#kevin-Kudu:~/programming/rn4$ adb devices
adb server is out of date. killing...
cannot bind 'tcp:5037'
ADB server didn't ACK
* failed to start daemon *
error:
I get the same result when I try to run the app.
Any ideas what I should try next? Please bear in mind that I am still fairly new to linux so please be specific. If you tell me, "Simply change the RX74 constant in the Fetzer config file" I'm not going to have any idea what you are talking about. (I've had bad experiences with linux advice that assumes that I know what every file on the system is and where to find it.)
Thanx in advance.
ADDENDUM 1 #Vigas Deep:
When I check which -a adb:
kevin#kevin-Kudu:~$ which -a adb
/usr/bin/adb
/usr/bin/adb
/home/kevin/Android/Sdk/platform-tools/adb
So I have more than one. I'll figure out why one is getting called twice, for now I just rename it, and now I get:
kevin#kevin-Kudu:~$ which -a adb
/home/kevin/Android/Sdk/platform-tools/adb
I fire up the Android Studio virtual device and check it:
kevin#kevin-Kudu:~$ adb devices
List of devices attached
emulator-5554 device
And when I try to run a RN starter app:
kevin#kevin-Kudu:~/programming/rn4$ react-native run-android
Scanning folders for symlinks in /home/kevin/programming/rn4/node_modules (18ms)
Starting JS server...
Building and installing the app on the device (cd android && ./gradlew installDebug)...

Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:
https://facebook.github.io/react-native/docs/getting-started.html
Interestingly, when I try to restart the adb server, I get:
kevin#kevin-Kudu:~/programming/rn4$ sudo adb kill-server && adb start-server
[sudo] password for kevin:
sudo: adb: command not found
Does the adb in the SDK not have those commands?
Just for kicks, I reboot and try pluggin in a tablet:
kevin#kevin-Kudu:~$ adb devices
List of devices attached
5205132d4f9011af device
(But for some reason only shows up when plugged into the USB2 port, very inconveniently located.)
When I try to run the RN project:
kevin#kevin-Kudu:~/programming/rn4$ react-native run-android
Scanning folders for symlinks in /home/kevin/programming/rn4/node_modules (21ms)
Starting JS server...
Building and installing the app on the device (cd android && ./gradlew installDebug)...
Error occurred during initialization of VM

Sorry, that's all the testing I can do for now. Any other ideas?
ADDENDUM 2 #Vigas Deep:
"just to make sure that its using the adb located inside sdk; use this command for now: /home/kevin/Android/Sdk/platform-tools/adb devices"
OK, I get the same result whichever I use.
"and do not use sudo for adb command because we are not going to run react-native run-android as sudo."
OK. All the examples I saw used sudo to start and kill the adb server. Strangely, now it works without sudo but not with. Before, I think it was the opposite, but I haven't tried it without in a long time so I can't be sure.
"Also; are you using openJDK or oracleJDK ; how did you install the JDK?"
I thought I remembered going to the Oracle site, but when I do "java -version", I get:
kevin#kevin-Kudu:~/programming/rn4$ java -version
java version "1.7.0_95"
OpenJDK Runtime Environment (IcedTea 2.6.4) (7u95-2.6.4-3)
OpenJDK 64-Bit Server VM (build 24.95-b01, mixed mode)
This would seem to indicate otherwise. Should I change it?
ADDENDUM 3 #Vigas Deep:
OK, I looked up how to remove openjdk and followed it. I found instructions about how to install the jdk8, just to be sure. I am getting the same error when I try to run the RN app. When I check java -version:
kevin#kevin-Kudu:~/programming/rn4$ java -version
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)
and
kevin#kevin-Kudu:~/programming/rn4$ readlink -f $(which java)
/usr/lib/jvm/java-8-oracle/jre/bin/java
When I check the jvm folder:
kevin#kevin-Kudu:/usr/lib/jvm$ ls
java-8-oracle
Just in case, here is my current $PATH:
kevin#kevin-Kudu:/usr/lib/jvm$ echo -e ${PATH//:/\\n}
/home/kevin/bin
/home/kevin/.local/bin
/usr/local/sbin
/usr/local/bin
/usr/sbin

/usr/local/games

/usr/lib/jvm/java-8-oracle/db/bin
/usr/lib/jvm/java-8-oracle/jre/bin
/home/kevin/Android/Sdk/tools
/home/kevin/Android/Sdk/platform-tools
Any other ideas? Am I missing something? (highly likely)
ADDENDUM 4 #Vigas Deep:
OK, so completely removed Java, mainly following this.
I reinstalled it using this.
After some monkeying around with genymotion, I was able to get an app started on create-react-native-app that ran on genymotion.
Thank you #vigas-deep. If you're even in Oakland, I owe you a beer, or whatever your beverage of choice is. Thanx!
I have eight years of experience with Ubuntu and other Linux based OSes.
I think the problem is you are having multiple versions of ADB.
run the following command to know if that's right.
which -a adb
And if you have multiple versions of adb, just keep the adb version which is inside your android sdk and remove/rename others.
prefer rename just incase if you need those executables again.
I'd be happy to help more if needed.

adb socket not working and daemon

I am getting this type of error
error: could not install smartsocket listener: cannot bind to

of 'adb version'
my genymotion device is running but it shows me that no device
I came across the same error. I provided the below command and the issue got solved.
COMMAND :- taskkill /f /im adb.exe
Close Eclipse or Android Studio if either is running (Optional).
Open Command Prompt.
Go to the Android SDK platform-tools directory.
Type adb kill-server.
Type adb start-server.
If no error message is thrown while starting ADB server, then adb is started successfully.
OR
Go to Task Manager, open the Processes tab, and end the adb.exe process.
Then restart Android Studio.
This may work if there is any problem with adb.
In my case, none of the above solution worked. I solved it strangely maybe it can be a bug.
Do not run Genymotion emulator before Android Studio. Firstly, I opened android studio then I clicked run project and select deployment target windows appeared. Then I run genymotion emulator and now the emulator is shown in the select deployment target windows in Android Studio. Then deployed to the emulator without errors. Done!
As another way, you can try to set Genymotion sdk to the same as Android studio sdk. To do this, first find your sdk location. You can find it by right clicking the Android Studio project -> Open Module Settings-> Select SDK location -> under Android SDK location, it is shown. Then open Genymotion -> Settings -> ADB tab -> Click Use custom Android SDK tools radio button -> navigate to SDK folder used by Android studio -> Restart Genymotion virtual device
If none of the above worked for you, just make sure that you have closed Genymotion emulator as it caused this issue with me.
Easiest Way! I just ran into this issue trying to connect a React-Native App to an Android Studio emulator. If you read the error message it tells you that "Only one usage of each socket address (protocol/network address/port) is normally permitted." So you can assume that something other than React-Native is also attempting to connect to the emulator.
Terminate The Connections:
Leave the emulator running.
Close out of and uninstall any Android Studio/Eclipse Apps you have on the emulator. This terminates apps trying to connect.
Close Eclipse or Android Studio if either are running. Android Studio doesn't have to be open in order for the emulator to work (This is important). This terminates software trying to connect.
After doing so I went back into my React-Native App and connected to Expo no problem.
All you have to do is terminate all connections. However you so choose.
I came across the same error, it worked simply after restarting the AS on windows, of course, it asked for SDK update.

Can't start Genymotion Emulator from Android Studio Plugin

I've seen many posts with a similar problem and tried many solutions but so far none have helped. This all started after I upgraded Genymotion from 2.5.2 to 2.6.0.
I'm using Android Studio 1.5.1 on Ubuntu 15.10 64 bit. The Genymotion plugin is version 1.0.7. VirtualBox is 5.0.12 r104815
When I try to start a Genymotion Emulator I get:
I have several machines defined and all do this.
However, I can start them from the Genymotion app.
One other piece of information...if I have Android Studio and Genymotion running I get the following error when I try to issue any adb command from the command line:
adb server is out of date. killing...
cannot bind 'tcp:5037'
ADB server didn't ACK
* failed to start daemon *
error:
I've tried restarting the computer, restarting Android Studio, and removing and reloading the plugin. I've also set Genymotion to use the same adb that Android Studio uses.
Any ideas? Let me know if you need more info.
Thanks,
Rich
This is actually 2 separate problems and I've found the solution for one and a workaround for the other.
Can't start Genymotion Emulator from Android Studio Plugin - I resolved this for now by reverting to Genymotion 2.5.2. I'll still need to figure out why 2.6.0 causes a problem but for now I can start emulator machines from the Android Studio plugin.
adb server is out of date - This is caused by more than one instance of adb on the machine. In my case, Android Studio was using the one in ~/Android/Sdk/platform-tools, but when I tried issuing adb commands in terminal it was using the one in /usr/bin. I'll either try creating a symbolic link in /usr/bin to point to ~/Android/Sdk/platform-tools, or I'll add ~/Android/Sdk/platform-tools to my Path environment variable.
