Question

我想使用最新的android studio，并且导入了旧版本代码并在更新后更新android studio我遇到以下错误 gradle android studio更新后

Manifest merger failed : Attribute application@appComponentFactory
 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:5:1-38:15 to override.

我在清单中添加了上述错误中提到的一个标签

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

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.GET_ACCOUNTS" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        tools:replace="android:appComponentFactory"
        android:theme="@style/AppTheme">

但是在此之后发生另一个错误，请我解决我从前一天就被卡住了这个错误

    org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:processDebugManifest'.
    at org.gradle.api.internal.tasks.execution.ExecuteActionsTaskExecuter.executeActions(ExecuteActionsTaskExecuter.java:103)

    at org.gradle.api.internal.tasks.execution.SkipUpToDateTaskExecuter.execute(SkipUpToDateTaskExecuter.java:59)

我的gradle文件是

     compileSdkVersion 28
    defaultConfig {
        applicationId "app.digiskills.com.digiskillsapp"
        minSdkVersion 19
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {

    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.2'

    annotationProcessor 'com.google.dagger:dagger-compiler:2.10'
    implementation "com.mikepenz:materialdrawer:6.1.0"

Answer 1

最后，我通过替换此问题解决了

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'com.android.support:appcompat-v7:28.0.0-alpha3'
    implementation 'com.android.support.constraint:constraint-layout:1.1.1'

    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

    implementation 'com.android.support:design:28.0.0-alpha3'
    implementation 'com.android.support:cardview-v7:28.0.0-alpha3'
}

Answer 2

通常，要查看错误是什么，您可以在Android Studio中查看合并的清单文件

转到清单文件

单击底部的“合并清单”标签

在右侧屏幕上的“其他清单文件”中，检查是否由于梯度而导致任何错误

Answer 3

在tools:replace="android:appComponentFactory"上添加AndoridManifest.xml也不能解决我的问题。

与mentioned here一样，在这里（Getting Started），您可能需要转到：

Refactor -> Migrate to Android X

然后，就可以使用了。

_{请注意，您还需要在xml端更改xml代码。}

例如（那些应该以{{1}}开头）：

androidx

Answer 4

将android:appComponentFactory添加到您的清单

<application
  android:appComponentFactory="android.support.v4.app.CoreComponentFactory"
  tools:replace="android:appComponentFactory">

在3.1.4上更新android studio 3.2时出现清单合并问题
