我还有下一年级

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0-rc01'
    implementation 'com.android.support.constraint:constraint-layout:1.1.2'
    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.google.android.material:material:1.0.0-rc01'
}

但当我想要构建应用程序时,我得到下一个日志:

Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0-alpha3] AndroidManifest.xml:22:18-91
    is also present at [androidx.core:core:1.0.0-alpha3] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
    Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:5:5-19:19 to override.

好!去显化并去做:

<?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="ru.chopcode.myapplication">

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

</manifest>

然后我在我的Logcat中得到这个错误:

Manifest merger failed with multiple errors, see logs that I have Linked with it

首先,一定要在manifest标签中添加这一行

xmlns:tools="https://schemas.android.com/tools"

然后在Android studio中添加工具替换建议的工具

其他回答

从Android P开始,支持库已经转移到AndroidX

请从本页重构你的库。

首先,一定要在manifest标签中添加这一行

xmlns:tools="https://schemas.android.com/tools"

然后在Android studio中添加工具替换建议的工具

1.在app/build.gradle的末尾添加了这些代码:

configurations.all {
   resolutionStrategy.force 'com.android.support:support-v4:28.0.0' 
   // the above lib may be old dependencies version       
    }

2.修改sdk和tools版本至28:

compileSdkVersion 28
buildToolsVersion '28.0.3'
targetSdkVersion  28

3.在你的AndroidManifest.xml文件中,你应该添加两行:

<application
    android:name=".YourApplication"
    android:appComponentFactory="AnyStrings"
    tools:replace="android:appComponentFactory"
    android:icon="@drawable/icon"
    android:label="@string/app_name"
    android:largeHeap="true"
    android:theme="@style/Theme.AppCompat.Light.NoActionBar">

或者简单地

进入Refactor (Studio -> Menu -> Refactor) 单击“迁移到AndroidX”。它的工作 这是工作。

我在和Groupie合作时也犯了同样的错误。 实现“com.xwray:追星:tripwire”

我通过将版本改为实现“com.xwray:groupie:2.1.0”来解决这个问题。

遵循以下步骤:

去重构和点击迁移到AndroidX 单击执行重构
