does your project use kapt?
If so, you can disable the cache of kapt.
Open your build.gradle file in the app module, and set the useBuildCache to false, and sync the Gradle.
Try to rebuild your code.
kapt {
useBuildCache = false
}
If everything goes fine, you can enable useBuildCache again.

Execution failed for task ':react-native-keychain:compileReleaseJavaWithJavac'. when trying to ./gradlew bundleRelease

I am trying to get the .aab and the .apk files to publish the android side of a react-native app to the Google Play Store.
After about 2 minutes of working Task :react-native-keychain:compileReleaseJavaWithJavac FAILED is printed.
It gives a little more information but I have been unable to find anything that fixes this error.
Execution failed for task ':react-native-keychain:compileReleaseJavaWithJavac'.

Note: Recompile with -Xlint:deprecation for details.
I have also run the app in android studio and get the same error. I am especially confused because the app works when I run the npx react-native run-android command.
If any more information is needed please let me know and thank you in advance for any help!

One of the below should work for you:
Edit your build.gradle like below
allprojects {
tasks.withType(Javadoc).all { enabled = false }
repositories {
...
}
}
If the above did not work, try below
simply comment out supportLibVersion from your build.gradle then clean and rebuild.

Library module not working in my projects app module android

I have created a library module which contains some activity and transactions logic, which will further be used by different existing applications. The library module uses androidx but my existing projects dont uses the androidx. Also I dont want to messed up with my existing project.
Added module dependency to the project
implementation project(':abcdSDKModule')
After importing the library module I got lots of error like

Realm messes with Android data binding

I have an app that builds OK but as soon as I make one of my classes Realm-aware by either #RealmClass/RealmModel or RealmObject I get a ton of errors like those below.
Is this a bug or am I doing something wrong?

open class AccountData (

set(value) { _type = value.name }
var currency : CurrencyType // <-- this is not a supported field type
get() = CurrencyType.valueOf(_currency)
set(value) { _currency = value.name }
}
You need to mark unsupported "helper" fields with #Ignore annotation.
#field:Ignore
var type : AccountType // <-- this is not a supported field type
get() = AccountType.valueOf(_type)
set(value) { _type = value.name }
#field:Ignore
var currency : CurrencyType // <-- this is not a supported field type
get() = CurrencyType.valueOf(_currency)
set(value) { _currency = value.name }
}

While building Project, error in :app:compileDebugJava. It says error: package android.support.v7.app does not exist

I have all the required dependencies in the Module Settings. I have also installed all the support libraries using the sdk manager.
I get the following output from the Gradle Console

I have tried multiple existing posts regarding this but have failed to find a solution that works.
EDIT: My build.gradle file.
apply plugin: 'com.android.application'
android {
compileSdkVersion 21

defaultConfig {
applicationId "com.projectunicorn.shoppingwithfriends"

compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.google.android.gms:play-services:6.5.87'
compile ('com.android.support:appcompat-v7:21.0.3')
compile ('com.android.support:support-v4:21.0.+')
}
I'm using Android Studio 1.0.2 on OS X Yosemite.

Installing the library is not enough. You also need to add it to the list of dependencies of your project.
To do that, add this line to the dependencies section of your build.gradle:
dependencies {
...
compile ('com.android.support:appcompat-v7:21.0.3')
compile ('com.android.support:support-v4:21.0.3')
}
This was taken from the official docs:
v7 appcompat library
Note: This library depends on the v4 Support Library. If you are using Ant or Eclipse, make sure you include the v4 Support Library as part of this library's classpath.
So don't forgot to add both v4 and v7.

What versions do you choose when create project? (target, minimum, etc)
I change all to one version - API 21, it works for me.
