Anybody succeeded with Room and multi modules?

// shared module, not depending on android
interface Dao {
  suspend fun getAll(): List<A>
}

// android
@Dao
interface RoomDao {
    @Query("select * from a")
    override suspend fun getAll(): List<A>
}

I am always getting

An abstract DAO method must be annotated with one and only one of the following annotations: Insert,Delete,Query,Update,RawQuery - Dao.getAll()

Do I really have to annotate the

Dao.getAll

too, even if I override this function in RoomDao with the one annotation? https://medium.com/androiddevelopers/7-pro-tips-for-room-fbadea4bfbd1#dd40

How to get the status of bluetooth on/off using broadcast receiver defined in Manifest

<receiver
    android:name="org.kp.m.arrivalnotification.usecase.BluetoothStatusReceiver"
    >
    <intent-filter>
        <action android:name="android.bluetooth.adapter.action.STATE_CHANGED" />
    </intent-filter>
</receiver>

this doesn’t help. I was thinking, this is exempted list of receivers 🤔 Appreciate the help in advance 😇

Can we use this kind of response For paging library 3 ?

Hey anyone know how to disable 3rd party keyboard in our app. Thanks in advance

Hi, we’re working on our upgrade from Kotlin 1.4.32 to 1.5.21. We’re seeing a large regression in both app size and startup performance, which seems to be due to R8 now poorly handling lambda classes (eg, merging seems to not be working). Anyone else face this or have ideas how to resolve?

hi guys, is this the right way to use

@Parcelize

on kotlin sealed classes:

sealed class MySealedClass : Parcelable {
    @Parcelize object Object1: MySealedClass()
    @Parcelize object Object2: MySealedClass()
    @Parcelize object Object3: MySealedClass()
}

I am getting the error:

android.os.BadParcelableException: ClassNotFoundException when unmarshalling: com.myapp.data.MySealedClass$Object1

when try to create the Intent….

Hi guys, I did set up Hilt dependency following this. I am using @HiltAndroidApp on BaseApplication class and @AndroidEntryPoint on MainActivity. But I am getting this error:

java.lang.RuntimeException: Unable to instantiate application com.sample.gitapp.BaseApplication: java.lang.ClassNotFoundException: Didn't find class "com.sample.gitapp.BaseApplication" on path: DexPathList[[zip file "/data/app/com.sample.gitapp-2/base.apk"],nativeLibraryDirectories=[/data/app/com.sample.gitapp-2/lib/arm64, /system/lib64, /vendor/lib64, /system/vendor/lib64]]

Any idea on it?

Hi! Is it still better to use Android Studio over Intellij Ultimate for android projects?

Hey Guys! Just wanted to ask that Is there any better way to refresh the item views of a recycler view without actually notifying the adapter to refresh the whole thing?

Good day guy, I am new to android programming. May you please share with me any jetpack-compose library for a donut chart.

😶 is excessive IMHO. Curious if the community feels strongly in favour of not allowing #android discussion which isn't related to the #kotlin language?

Are there any performance benchmarks for

Flow

support in Room ? How many updates it could consistently reflect? I have a fragment with recyclerview listening for realtime DB changes using

Flow<List<T>>

for a

select *

query and am performing ~10 writes/sec with

REPLACE

strategy, in the background. This results in dropping out some records (if there are 2 records in the list being updated frequently, they get merged into one, while having different values for primary key) I'm not sure what exactly is a bottleneck here because SQLITE can easily handle these many writes.

Hello everyone, I'm looking for a good example of combining compose and an existing app, maybe someone has a link?

Using the Jetpack Navigation library, how do you handle an optional Long id that you send to an add/edit screen? Longs can't be nullable in the Navigation library so do I set the default value to -1 instead?

I have a problem for load data in server using retrofit some idea for what's a problem? i'm using my own server this in azure.

How do I bing a service with kotlin

    bindService(nokeServiceIntent, mServiceConnection, Context.BIND_AUTO_CREATE)
}

thats the function I'm trying to implement but can't seem to figure out how to bind the service

Hello, is it ok to use a ViewModel for different fragments/activities?

Hello. Is there any way to send data to previous activity other than using startActivityForResult or storing it in preferences?

“Cascade if can be replaced with when” warning but sometimes it’s a false positive, for example if I have an
