我的项目运行良好，没有在我的应用程序中实现ViewPager2 gradle。但是当我在项目中使用gradle implementation 'androidx.viewpager2:viewpager2:1.0.0-alpha01'时，它给了我这个Log-cat错误...

与此
implementation group: 'androidx.viewpager2', name:'viewpager2', version: '1.0.0-alpha01'相同的错误然后我创建了另一个空项目并实现了
implementation 'androidx.viewpager2:viewpager2:1.0.0-alpha01'它给了我这个错误.....
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:1.1.0-alpha04] 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.
在特定于错误的上方，在
android.support.v4.app.CoreComponentFactory和implementation 'com.android.support:appcompat-v7:28.0.0'之间存在冲突。所以我从项目中删除了implementation 'androidx.viewpager2:viewpager2:1.0.0-alpha01'库。现在正在工作。
我的问题是
如果删除
support:appcompat，则无法使用AppCompatActivity及其用途。这存在于我现有的应用程序中。如何解决呢？
如何同时使用
support:appcompat和ViewPager2？编辑
在清单的
support:appcompat标记内添加tools:replace="android:appComponentFactory"后，@ ManoharReddy。它给我这个错误org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:processDebugManifest'.

最佳答案
我找到了解决方案。
正如@Kishore和@Shweta告诉您的，在项目中迁移AndroidX是解决方案。
手动添加android.useAndroidX=true和android.enableJetifier=true给了我很多时间。因为它抛出了一些错误或Suggestion: add 'tools:replace="android:appComponentFactory"' to <application>
要在项目中启用Jet-fire，android Studio中有一个选项
选择您的项目--->右键单击
app ---->重构---->迁移到AndroidX
如下图所示：
单击“迁移到AndroidX”后。
它将要求您确认并备份您的项目。
最后一步，它将要求您进行重构。
完成重构后，检查gradle.properties是否具有android.useAndroidX=true和android.enableJetifier=true。如果不是，则将这两行添加到gradle.properties文件中：
android.useAndroidX=true
android.enableJetifier=true
