当我在依赖项中添加到这一行时，implementation 'com.theartofdev.edmodo:android-image-cropper:2.8.+'它会导致错误

*我的错误*

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:8:5-25:19 to override.

和

implementation 'com.android.support:appcompat-v7:28.0.0'

这条线变成红线

我认为问题是版本原因

我怎样才能避免这种冲突呢？

我已经尝试更改版本并在清单中添加代码

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<usespermissionandroid:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

但没用

这是我的清单

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

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

    <application
        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">
        <activity android:name=".Activities.LoginActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".Activities.RegisterActivity" />
        <activity android:name=".Activities.PostActivity" …

迁移 androidx 后，当我单击按钮时，它会向我显示\n为什么会发生这种情况？

当我点击按钮打开日历时我想要做什么

这是我点击按钮时的错误

  java.lang.ClassNotFoundException: Didn\'t find class "com.example.blogapp.whateverString" on path: DexPathList[[zip file "/system/framework/org.apache.http.legacy.boot.jar", zip file "/data/app/com.example.blogapp-BjDX\n

这是我的 Manifest.xml，其中有任何字符串的形式

<?xml version="1.0" encoding="utf-8"?>\n<manifest xmlns:android="http://schemas.android.com/apk/res/android"\n    xmlns:tools="http://schemas.android.com/tools"\n    package="com.example.together">\n    <!--\n         The ACCESS_COARSE/FINE_LOCATION permissions are not required to use\n         Google Maps Android API v2, but you must specify either coarse or fine\n         location permissions for the \'MyLocation\' functionality.\n    -->\n    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <!-- \xeb\xa7\xb5 \xec\x9d\xb4\xec\x9a\xa9\xed\x95\x98\xea\xb8\xb0 \xec\x9c\x84\xed\x95\xa8 -->\n    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />\n    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <!-- \xeb\x8b\xa4\xec\x9d\x8c \xec\xa7\x80\xeb\x8f\x84 -->\n    <uses-permission android:name="android.permission.INTERNET" …
