（Error）—— Attribute application@icon value=(@mipmap/ic_launcher) from AndroidManifest.xml:7:9-43

出现这个问题可以尝试在AndroidManifest.xml文件中进行一下修改

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.duxiaoye.project649_9005"
    xmlns:tools="http://schemas.android.com/tools"> //****修改****

    <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/Theme.AppCompat.Light.NoActionBar"  //****修改****
        tools:replace="android:icon, android:theme"> //****修改****
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
