Failed to execute aapt with cordova

I am working on a cordova project that has been working fine for a while, and suddenly I started to get a very strange error whenever the build reaches ":app:processArm64DebugResources" when builing with the command "cordova run android --device".
I have tried removing and adding platforms, running the clean command, updating plugins and more. This error only affects one of my Cordova projects though, when I try to build other projects there is no error.
Here is the output:

Add this plugin to the project and it will fix everything
cordova plugin add cordova-android-support-gradle-release --fetch
This has something to do with an update Google did to Android 28 rc that adds two new fields. Thank the gods someone shared a plugin to the world to fix it.

I tried the solution shown here, and now, I built successfully with Android.
Open file platforms/android/app/build.gradle
add
configurations.all {
resolutionStrategy {
force 'com.android.support:support-v4:27.1.0'
}
}
after
dependencies {
...
}

This happened to me in July 2020 on a Ionic V1 project, my way to fix it was to upgrade cordova-android from 7.1.4 to the most recent, which was 9.0.0 at the time, and also change the min android sdk version.
ionic cordova platform rm android
// if your project had much trouble building and you prefer a clean build, you may do:
// rm -rf node_modules platforms plugins package-lock.json
// npm install (and maybe npm audit fix later)
ionic cordova platform add android#latest
In config.xml, change or add this (the value 22 may be different in your time):
<preference name="android-minSdkVersion" value="22" />
And finally I was able to build with
ionic cordova build --release android

I had the same error. In my case I had to remove in my config.xml the following line:
<preference name="Orientation" value="all" />

EDIT:
I solved the Problem by deinstalling all plugins an installing them one by one.
The plugin BarcodeScanner was the problem (here). Changing the value compile 'com.android.support:support-v4:+' to compile 'com.android.support:support-v4:23+' in the starter-barcodescanner.gradle file under platforms/android/phonegap-plugin-barcodescanner resolved the problem.

Some plugins may encounter incompatibilities due to new updates of Android Support Libraries as explained in other replies here.
Easiest fix is by installing "cordova-android-support-gradle-release" plugin. This plugin will automatically align the version of the plugin which crashed and you can continue to use your plugin.
Also this fix is persistent compared with manually change the version directly into the plugin.
cordova plugin add cordova-android-support-gradle-release --fetch
Also you may have a look into the documentation and other related issue here

This build failure is due to a major version release of the Google Play Services and Firebase libaries on June 17.
Worked for me
Run:
ionic cordova platform rm android
if your using firebase
cordova plugin remove cordova-plugin-firebase
cordova plugin add cordova-plugin-firebase-lib
Run:
ionic cordova plugin add cordova-plugin-androidx
Run:
ionic cordova plugin add cordova-plugin-androidx-adapter
Run:
ionic cordova platform add android#8.0.0
Enjoy with your apk
ionic cordova build android --prod --release

I found my answer here:
Build Error -Ionic Cordova fails for android
Also, mine required a similar fix as above only it was in the de.appplant.cordova.plugin.local-notification plugin. I changed ‘com.android.support:support-v4:+’ to ‘com.android.support:support-v4:23+’ and then removed and added the android platform and it built. However, I had an extra brace '}' in my build-extras.gradle that had to be removed also.

I can verify the gradle-plugin fixed it.
Tried the support-version numbers before but the plugin was the only thing that solved it for me after 3 weeks of debugging!

Android Studio 3.0.1 - Getting AAPT2 errors

So I am kinda new with making apps in Android Studio. I want to make this personal project, an app timetable of incoming buses for my city transit. When I started the project, the app would sucessfully load without errors, but lately I've been getting these AAPT2 exception errors and failings with manifest processing.
The Android Studio version is 3.0.1
I heard that it is possible to fix some errors with AAPT2 by updating the "Android SDK build-tools", the version now is 27.0.1.
I also tried to add android.enableAapt2=false to gradle.properties, but nothing was fixed.
Someone suggested to change compileSdkVersion. It is set at 27 now and changing it doesn't do anything.

I seriously don't know what happened. I tried moving the project to a different computer, but the errors are still there.
Thank you.

Try disabling the AAPT2 by adding android.enableAapt2=false to your gradle.properties file.
For AAPT2 it required formated AndroidMenifest file follow the below link for further details
Reference : here
I was using Android studio 3.0.1 In which I disabled the AAPT2 and it resolved my error.

Android Studio "error: failed to read metadata" after update to 3.0.0

I've updated Android Studio to v3.0.0 and now I cant build my project.
Android Studio add .flat to resources file names on build and the build crash because it can't recognize the .flat extension.
I've tried to clean the project and rebuild it but I still get this error.
I don't have any idea of what could cause this.
I hope someone can help me solve my problem cause since Studio can't do a successful build, it can't find my dependencies and I can't work.

I believe this is a bug in the new version of AAPT that comes with Android Studio 3.0.0
As a workaround, you can revert to an earlier version of AAPT by adding the line:
android.enableAapt2=false
to the file:
gradle.properties
This should also fix other problems with the upgrade to AAPT2.

The problem isn't the .flat files format. The issue is that AAPT2 has trouble linking some raw files (all files bigger than 68 MB, some files that are smaller too). Please follow the issue tracked on https://issuetracker.google.com/68425589 for updates.
Update:
The issue has now been fixed, so if you use AGP 3.2.0-alpha11 or newer you should not be getting this error anymore.
