Android: PreviewView causes crash in dynamic feature module

Question

I am trying to create an on-demand feature module using the androidx.camera package. I am getting a crash when the activity inflates the layout which includes the PreviewView. Note, the module loads correctly and show the correct layout if I just use something simple like a TextView, so I don't think (hopefully anyways) that it's an issue with my dynamic feature setup/download.

Also this all works fine if I include the camera dependencies in the base app module, however it seems like I should be able to do that in the dynamic feature module. I'm not sure what i'm missing.. Anyone come across this before?

feature-module's build.gradle:

apply plugin: 'com.android.dynamic-feature'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-kapt'

android {
    compileSdkVersion 29

    defaultConfig {
        minSdkVersion 23
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}
dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation project(':app')

    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.3.71"
    implementation 'androidx.appcompat:appcompat:1.2.0'
    implementation 'androidx.core:core-ktx:1.3.1'

    def constraintLayoutVersion = "2.0.0-beta3"
    implementation "androidx.constraintlayout:constraintlayout:$constraintLayoutVersion"

    // CameraX core library
    def camerax_version = "1.0.0-beta06"
    implementation "androidx.camera:camera-core:${camerax_version}"
    implementation "androidx.camera:camera-camera2:${camerax_version}"
    implementation "androidx.camera:camera-lifecycle:${camerax_version}"
    implementation "androidx.camera:camera-view:1.0.0-alpha13"
    implementation "androidx.camera:camera-extensions:1.0.0-alpha13"

    implementation "androidx.gridlayout:gridlayout:1.0.0"
    implementation "androidx.palette:palette:1.0.0"
    implementation "androidx.recyclerview:recyclerview:1.0.0"

}

activity layout file:

<?xml version="1.0" encoding="utf-8"?>
<layout
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:android="http://schemas.android.com/apk/res/android"

    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    <androidx.camera.view.PreviewView
        android:id="@+id/viewFinder"
        android:layout_width="match_parent"
        android:layout_height="450dp"
        app:layout_constraintTop_toTopOf="parent" />
    </androidx.constraintlayout.widget.ConstraintLayout>
</layout>

Activity in feature module:

class PhotoActivity: AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_photo)
    }

    override fun attachBaseContext(newBase: Context?) {
        super.attachBaseContext(newBase)
        SplitCompat.installActivity(this)
    }
}

Answer 1

It might help someone out there, my issue was not including the required

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

in my app's build.grade file. It's mentioned here

Answer 2

For anyone else that might run across something like this -- My fix was to include the LiveData dependency in my base module:

implementation "androidx.lifecycle:lifecycle-livedata-ktx:2.2.0"

In our case, the use of CameraX preview in the feature module was causing an xml inflate exception Error inflating class androidx.camera.view.PreviewView , adding the above code to the base module fixed the issue. Hope it helps. – Hagood

Answer 3

My issue was also the same. The error I got was

 Caused by: java.lang.NoSuchMethodError: No direct method <init>(Ljava/lang/Object;)V in class Landroidx/lifecycle/MutableLiveData; or its super classes (declaration of **'androidx.lifecycle.MutableLiveData'** appears 

By adding androidx.lifecycle.MutableLiveData dependency to the base module fixed the issue.

implementation "androidx.lifecycle:lifecycle-livedata-ktx:2.3.1"
