ionic cordova run android fails at invalid adb location?

I'm trying to get a brand new set up in place to run the example Ionic 4 app on an android device. I'm running on a brand new iMac and have installed all the needed prerequisites (ionic cli, npm, JDK8, Gradle, Android SDK, set up environmental variables, etc.) All latest version, fresh install.
I'm able to create the example app, add android platform, and build fine. But when I try to run to a device I get this error:
cordova build android
native-run android --app platforms/android/app/build/outputs/apk/debug/app-debug.apk --forward 8100:8100
[native-run] Error: spawn /Users/mike/Library/Android/sdk/platform-tools/adb ENOENT
[native-run] at Process.ChildProcess._handle.onexit (internal/child_process.js:267:19)
[native-run] at onErrorNT (internal/child_process.js:469:16)
[native-run] at processTicksAndRejections (internal/process/task_queues.js:84:21)
[ERROR] An error occurred while running subprocess native-run.
What concerns me is the file path shown (.../sdk/platform-tools/adb) is different from where I see the location when navigating there myself (i.e. the fresh install of Android Studio has this at the location .../sdk/platform-tools/platform-tools/adb .... (note the extra "platform-tools" folder.
When I run "adb devices" it works, but only when I have the environmental variable (PATH) set to .../platform-tools/platform-tools/adb but when I try the ionic run command its obviously trying the other location. How? Why? What did I install wrong???

After much toiling... final step was to completely uninstall and remove all components of Android Studio, then reinstall again. This solved it and removed the duplicate folders. No idea how it would have happened on a standard install but if anyone else experiences it, this would be my recommendation.

Can't able to run react native application on android device

Im Using MacBook Pro.. Im New To React Native.. After Creating An Project Im Running On iOS Device It's Running.. At The Same Time While I'm Running On Android Device Means Im Getting This Error.. Any One Please Help Me To Resolve This Error.. Im Using Visual Studio Code IDE For React Native Application
Thanks In Advance..

So you have two errors to fix here as your error log
local.properties file doesn't exist.
Failed to launch the emulator
local.properties file issue fixing
Open your react native project android folder using Android Studio.
Wait for gradle sync and clean the project and rebuild it using Android Studio
After that make sure you have local.properties file is been created inside android folder
If not try these steps to make local.properties file manually
Right click top level of project and Create new file 'local.properties' then add: sdk.dir=/Users/<YourUsername>/Library/Android/sdk
Clean and build
Before running your react native project on android make sure you have turn on the Android Emulator by AVD Manager in Android Studio
If you have not create any emulators then try this link - I have posted full answer on how to make Android Emulator -
React native failed to launch emulator
EDIT :
For adb error you need to install adb drivers on you Mac
Follow these steps
First install Homebrew using this command
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
or this command
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
After that install adb using homebrew
brew cask install android-platform-tools
Try to re run

Android Emulator does not run my app in react-native run-android

I get a react native configuration error when I run react-native run-android. The command gives this error message:
JS server already running.
Building and installing the app on the device (cd android && gradlew.bat installDebug)...
Error: Could not find or load main class JAVA_OPTS=-Xms256M
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 can not solve this. I installed all the dependencies. My emulator is also running but the application does not start.

try set up your Android development environment. config environment variable(like path), sure your android sdk tools (like adb) be find on runtime!

Build failed with ionic android

Maybe it can help you on build error with ionic/cordova error with android platform on windows
After install ant/ionic with :
%ANDROID_HOME%\tools;%ANDROID_HOME%\platform-tools;%ANDROID_HOME%\build-tools
start a new projet : ionic start hello blank ->ok
ionic platform add android -> ok
ionic build android - Error:
BUILD FAILED
C:\SDK\android-sdk\tools\ant\build.xml:954: The following error occurred while executing this line:

You may not have the required environment or OS to build this project
Paths are OK and if I start a new cordova projet (not ionic) build is a success.
If I check problem on c:\android-sdk\build.xml and I add
<echo>aapt: ${aapt}</echo>
I can see aapt.exe path is on android-21 (target is android-19)
For me, problem is I have two android sdk : android 19 and android 21. If I use CLI on windows, ionic/cordova choose android-21\aapt.exe by default and no android-19\aapt.exe
I tried to force Path with android version : %ANDROID_HOME%\build-tools\19.0.0 with no success.
To resolve this problem I changed paths to force on aapt executable path to point on android 19:
File c:\android-sdk\tools\ant\build.xml :
<aapt executable="C:\android-sdk\build-tools\19.0.0\aapt.exe" ...
</aapt>
This is not the best way, but I have not found another.

Instruction 1:
After adding your ANDROID_HOME, make sure you do the below:
Restart your System or run source ~/.bash_profile
Remove Android platform from your project ionic cordova platform rm android or ionic platform rm android
Add Android platform ionic cordova platform add android
Then ionic cordova run android or ionic run android
Instruction 2:
To set your ANDROID_HOME and JAVA_HOME, follow the below steps:
Run command open ~/.bash_profile
Paste the below in the file that opens on your Text editor
export ANDROID_HOME=/usr/local/Cellar/android-sdk/24.4.1_1
export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools
Save - "Command S" or "Ctrl S"
Then Follow the "Instruction 1:" above
NOTE: Make sure you have **24.4.1_1 SDK**
Hope this helps.

Build not found in Phonegap 3.0 for android

I have installed Cordova along with Phonegap and installed node.js in my system(ubuntu)
by using following commands:
Install Nodejs http://nodejs.org/
Install Cordova 3.0.x
$ sudo npm install -g cordova
Install Phone Gap 3.0.x
$ sudo npm install -g phonegap
Then i created project using phonegap command:
$ phonegap create hello
Trying to run into my local by using following command:
$ phonegap local run andriod
Now at first i am getting following error:
shoaib#shoaib:~/Documents/hello$ phonegap local run android
[phonegap] adding the Android platform...
[error] An error occured during creation of android sub-project. /home/shoaib/.cordova/lib/android/cordova/3.0.0/bin/create: line 54: jar: command not found
This i solved by running following command:
ls -la /home/shoaib/.cordova/lib/android/cordova/3.0.0/bin
Now when i again run
$ phonegap local run andriod
I am getting below error:
root#shoaib:/home/shoaib/Documents/hello# phonegap local run android
[phonegap] compiling Android...
[error] An error occurred while building the android project. /bin/sh: 1: /home/shoaib/Documents/hello/platforms/android/cordova/build: not found
I am using Android SDK 17
and version as 4.2.2 .
Any solution for this issue?

I had a similar problem. build and run were missing along with a few other files and lib was an empty directory. Downloaded cordova-android from here extracted and copied everything from its /bin/templates/cordova/ to the project (/platforms/android/cordova/). Then I could build and install the app.
Still had to start the emulator, check the running emulator with platforms/android/cordova/lib/list-started-emulators and then pass it when installing or it would take forever to install it on an emulator.
$ platforms/android/cordova/lib/list-started-emulators
emulator-5554
$ phonegap install --emulator=emulator-5554 android

I had already installed the JDK but the same error.
To fix this I just removed the phone test project and make sure that:
Java, javac and jar where in the path
(both should work)
java -version
javac -version
jar -version
Android sdk path was properly set and JAVA_HOME environment variable was properly set.
Then I remake the project and everything worked.

Hey got the solution.
I install open jdk 6.0 and problem is resolved.
