我在运行该应用时出现此错误：
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:1.0.0] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:6:5-30:19 to override.
当我在清单tools:replace="android:appComponentFactory"元素中添加<application>时，现在出现此错误：
Manifest merger failed with multiple errors, see logs
我不知道这意味着什么。.我只是想在我的应用程序中提供一些介绍，以便首次为我们的应用程序用户提供指南。
我有以下依赖性：
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation 'com.android.support:design:28.0.0'

}
这些清单代码：

我不知道这些错误是什么 和 我是我们应用程序的首次用户使用此Intro类：
package com.example.admin.test2;
import android.os.Bundle;
import android.widget.Toast;
import com.github.paolorotolo.appintro.AppIntro;
import com.github.paolorotolo.appintro.AppIntroFragment;

import androidx.fragment.app.Fragment;
public class Intro extends AppIntro {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
SliderPage sliderPage = new SliderPage();
sliderPage.setTitle("Track your expenses");
sliderPage.setDescription("You can check the list of your expenses along with the residual balance in the home screen");
sliderPage.setImageDrawable(R.drawable.home_screen);
sliderPage.setBgColor(getResources().getColor(R.color.pastelGreen));
addSlide(AppIntroFragment.newInstance(sliderPage));
SliderPage sliderPage2 = new SliderPage();
sliderPage2.setTitle("Change current date period");
sliderPage2.setDescription("You can change the current date period categorized to Daily, Monthly, Yearly, and All.");

addSlide(AppIntroFragment.newInstance(sliderPage2));

sliderPage3.setImageDrawable(R.drawable.income_tab);

addSlide(AppIntroFragment.newInstance(sliderPage3));
SliderPage sliderPage4 = new SliderPage();

sliderPage5.setImageDrawable(R.drawable.distribution2);

sliderPage6.setImageDrawable(R.drawable.savings2);
sliderPage6.setBgColor(getResources().getColor(R.color.pastelGreen));
addSlide(AppIntroFragment.newInstance(sliderPage6));
}
@Override
public void onDonePressed(Fragment currentFragment) {
super.onDonePressed(currentFragment);
Toast.makeText(Intro.this, "Pakyu tong introng to!", Toast.LENGTH_SHORT).show();
}
}
答案 0 :(得分：0)
第1步：在gradle.properties中添加以下代码段
android.enableJetifier=true
android.useAndroidX=true
第2步：在dependencies-Module:app文件的build.gradle部分中的以下代码段中添加
implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
implementation 'com.google.android.material:material:1.1.0-alpha04'
希望这会对您有所帮助。
