butterKnife10.1.0使用說明及報錯解決

一、引入步驟

1.在app的build.gradle中添加依賴

dependencies {
    implementation 'com.jakewharton:butterknife:10.1.0'
    annotationProcessor 'com.jakewharton:butterknife-compiler:10.1.0'
}
           

2.在app的build.gradle中添加java編譯版本說明

android {
    // Butterknife requires Java 8.
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}
           

二、注意事項

問題現象

引入後編譯報錯

Manifest merger failed : Attribute [email protected] value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91
    is also present at [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
    Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:36:5-364:19 to override.
           

按照以下提示修改了manifest檔案後繼續報錯

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:processDebugManifest'.
           

其實問題原因在于：Androidx和Android support庫不能共存

解決方法：轉換成androidX

1. 将build tools更新到3.2.0，gradle更新到4.6，依賴庫統一更新到28.0.0

2. 在gradle.properties檔案中添加

android.useAndroidX=true
android.enableJetifier=true
           

3. 工具欄選擇→Refactor→Migrate to Androidx...

4. 選中所有需要重命名的目錄，執行Do Refactor

5.修改所有類中的引用
