清单合并失败（AppIntro）

Question

运行应用时，我的应用中出现此错误：

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<application>元素中添加tools:replace="android:appComponentFactory" ，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..我只想在我的应用程序中介绍我们的应用程序的第一次用户的一些指南。

我有这些依赖：

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'
    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:support-v4:28.0.0'
    implementation 'com.android.support:recyclerview-v7:28.0.0'
    implementation 'com.github.razerdp:AnimatedPieView:1.2.4'
    implementation 'org.jetbrains:annotations-java5:15.0'
    implementation 'com.rengwuxian.materialedittext:library:2.1.4'
    debugImplementation 'com.amitshekhar.android:debug-db:1.0.5'
    implementation 'com.github.AppIntro:AppIntro:v5.1.0'
}

这些清单代码：

<?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.example.admin.test2">

        android:label="Pocket Budget"
        android:roundIcon="@mipmap/pblauncher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme"
        tools:ignore="GoogleAppIndexingWarning">

        <activity android:name=".MainActivity"

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".ScreenOne"
            android:windowSoftInputMode="adjustNothing"
            android:screenOrientation="portrait">
        </activity>
        <activity android:name=".Intro"
            android:screenOrientation="portrait"/>

    </application>

</manifest>

我不知道这些中的错误是什么，我的应用程序用户第一次使用此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 com.github.paolorotolo.appintro.model.SliderPage;

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.");
        sliderPage2.setImageDrawable(R.drawable.period2);
        sliderPage2.setBgColor(getResources().getColor(R.color.pastelGreen));
        addSlide(AppIntroFragment.newInstance(sliderPage2));

        SliderPage sliderPage3 = new SliderPage();
        sliderPage3.setTitle("Add your income");
        sliderPage3.setDescription("This is where you settle the amount of money needed in order to pay the expenses or how much money you have.");
        sliderPage3.setImageDrawable(R.drawable.income_tab);
        sliderPage3.setBgColor(getResources().getColor(R.color.pastelDarkbBlue));
        addSlide(AppIntroFragment.newInstance(sliderPage3));

        SliderPage sliderPage4 = new SliderPage();
        sliderPage4.setTitle("Add your expenses");
        sliderPage4.setDescription("This is where you put your expenses together with some details such as the amount, date, and others.");
        sliderPage4.setImageDrawable(R.drawable.expense2);
        sliderPage4.setBgColor(getResources().getColor(R.color.pastelRed));
        addSlide(AppIntroFragment.newInstance(sliderPage4));

        SliderPage sliderPage5 = new SliderPage();
        sliderPage5.setTitle("See the distribution of expenses");
        sliderPage5.setDescription("This is where the segments of the total expenses are found. It is shown in a pie chart form to easily recognize the difference of each expense.");
        sliderPage5.setImageDrawable(R.drawable.distribution2);
        sliderPage5.setBgColor(getResources().getColor(R.color.pastelPink));
        addSlide(AppIntroFragment.newInstance(sliderPage5));

        SliderPage sliderPage6 = new SliderPage();
        sliderPage6.setTitle("Record savings");
        sliderPage6.setDescription("You can check the total balance of your money and verify the savings that you will gain depending on the expenses that were added.");
        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();
    }
}

第1步：在gradle.properties中添加以下代码段

android.enableJetifier=true 
android.useAndroidX=true

第2步：在Module:app - build.gradle文件的dependencies部分中添加以下代码片段

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'

希望这会帮助你。
