多功能即時應用崩潰問題

Question

我是android中的Instant app的新手，請點擊以下鏈接以供參考： https : //codelabs.developers.google.com/codelabs/android-instant-apps/#6

具有單個功能的可安裝APK和Instant App運行正常。

但是，當我嘗試運行多功能即時應用程序時，它會崩潰（遵循上述鏈接中的步驟7）。

崩潰報告：

 E: FATAL EXCEPTION: main
    Process: com.bhaveshdesai.topekaapk, PID: 17609

Feature Gradle文件：

apply plugin: 'com.android.feature'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.0"
    dataBinding {
        enabled true
    }

    defaultConfig {
        minSdkVersion 19
        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 project(':topeka-base')
}

請幫助我解決此崩潰。

Answer 1

經過這么多嘗試，我發現了問題。

問題是由於使用android.support.v4.app.Fragment

將android.support.v4.app.Fragment更改為android.app.Fragment其工作即可。

Answer 2

當您對庫進行不兼容的二進制更改並且不重新編譯客戶端代碼時，通常會發生IncompatibleClassChangeError 。 請參閱什么原因導致java.lang.IncompatibleClassChangeError？ （但這可能不是造成您問題的真正原因）

在哪一步之后您會崩潰？

但是，我現在看到的是您的Feature gradle文件具有以下依賴項implementation project(':topeka-base') ，而該文件應包含api project(':topeka-base') 。 （假設您的Feature gradle = topeka-ui gradle）

topeka-ui / build.gradle

將所有預先生成的依賴項替換為以下依賴項：

 dependencies { api project(':topeka-base') } 

請仔細檢查代碼實驗室說明，以確保您沒有錯過任何步驟。
