My project has 3-4 module and one base module projects. I have already integrated all setup for multi feature instant app as per sample provide by google. https://github.com/googlesamples/android-instant-apps/tree/master/multi-feature-module

I have one module(apimodule) where i have added all libraries and API dependencies. Following is my project dependencies structure.

AppModule

Added all module as implementation

implementation project(':base')
implementation project(':module1')
implementation project(':module2')
implementation project(':module3')
wearApp project(':wear')

BaseModule ( Also added application project(':app') )

Added baseFeature true in gradle

feature project(':module1')
feature project(':module2')
feature project(':module3')
api project(':apimodule')

3. apimodule

Added baseFeature true in gradle

Here is my one module1 gradle file.

apply plugin: 'com.android.feature'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 26
    defaultConfig {
        minSdkVersion 23
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation project(':base')
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'

}

回答1:

As per my question I have added baseFeature true in two gradle files. One of base module gradle and one API module gradle and API module added as dependency project in base module.

What I have done is that refactor all code of API module into base module and make only one base module with baseFeature true.

This is only case solved my problem.
