How to pass an enum in AIDL?

How to pass an enum in AIDL? - android

Im trying to pass enums using AIDL and it's wrapping a Parcelable but it's still failing to compile with the following error:

implementing hilt in android with kapt Execution failed for task ':app:kaptDebugKotlin'

I have been using hilt in my several android projects. But since I have updated my android studio to latest version Chipmunk// 2021.2.1, this error comes every time when I just build project
Execution failed for task ':app:kaptDebugKotlin'.
A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptWithoutKotlincTask$KaptExecutionWorkAction
java.lang.reflect.InvocationTargetException (no error message)
I am checking it on sample app which is just just one dependency injection, using hilt and kapt.

Try using "annotationProcessor" instead of the "kapt" in the build.gradle dependencies. Worked for me.

gRPC code not being generated from proto file

I followed this guide to add gRPC to my Android project, but the proto file does not seem to generate code.
I placed book.proto under app\src\main\java\com\example\android together with my Kotlin code.

// Tar's:

What could be the problem?

Looks like the path of proto file is not correcttly. Try to move proto files to src/main/resouces/proto or set path in protobuf plugin configuration.
This is works well with kotlin DSL.
import com.google.protobuf.gradle.*
plugins {
java
idea

id("io.freefair.lombok") version "5.3.0"

implementation("io.grpc:grpc-netty:${grpcVersion}")

implementation("org.slf4j:slf4j-api:${slf4jVersion}")
implementation("org.slf4j:slf4j-simple:${slf4jVersion}")
testImplementation("junit:junit:4.13")
}
// Look here for set path
sourceSets {
main {
proto {
srcDir("src/main/resources/proto")
}
}
}
protobuf {
protoc { artifact = "com.google.protobuf:protoc:${protocVersion}" }
plugins {
id("grpc") {
artifact = "io.grpc:protoc-gen-grpc-java:${grpcVersion}"
}
}
generateProtoTasks {
ofSourceSet("main").forEach {
it.plugins {
id("grpc")
}
}
}
}

Cannot implement #Parcelize annotation

I am trying to implement #Parcelize annotation in kotlin to a data class, but it looks as if I forgot to implement something. Even when I try to import kotlinx.parcelize, Android Studio does not know the parcelize option. I implemented kotlin-parcelize and kotlin version is 1.4.21, which should be okay.
Here are my Gradle files:

How I tried to implement it.
import kotlinx.parcelize.Parcelize
import android.os.Parcelable
#Parcelize
data class Cipher(val id: Int, val name: String): Parcelable

Apply kotlin-android before kotlin-parcelize:
plugins {
id 'com.android.application'
id 'kotlin-android'
id 'kotlin-parcelize'
}

This works for me Add this to your build.gradle file
plugins {
id 'kotlin-android-extensions'
}

The setValue() function has Unresolved reference

fun saveImageInFirebase(){
var currentUser =mAuth!!.currentUser
val email:String=currentUser!!.email.toString()
val storage=FirebaseStorage.getInstance()
val storgaRef=storage.getReferenceFromUrl("gs://gameudemy.appspot.com")
val df=SimpleDateFormat("ddMMyyHHmmss")
val dataobj=Date()
val imagePath= splitString(email) + "."+ df.format(dataobj)+ ".jpg"
val ImageRef=storgaRef.child("images/"+imagePath )
imageSpace.isDrawingCacheEnabled=true
imageSpace.buildDrawingCache()
val drawable=imageSpace.drawable as BitmapDrawable
val bitmap=drawable.bitmap
val baos=ByteArrayOutputStream()
bitmap.compress(Bitmap.CompressFormat.JPEG,100,baos)
val data= baos.toByteArray()
val uploadTask=ImageRef.putBytes(data)
uploadTask.addOnFailureListener{
Toast.makeText(applicationContext,"fail to upload",Toast.LENGTH_LONG).show()
}.addOnSuccessListener { taskSnapshot ->
var DownloadURL= taskSnapshot.storage.downloadUrl.toString()!!
myRef.child("Users").child(currentUser.uid).child("email").setValue(currentUser.email)
myRef.child("Users").child(currentUser.uid).child("ProfileImage").setValue(DownloadURL)
loadTweets()
}
}
The setValue method called turns red and says Unresolved reference.
