配置文件

AndroidManifest.xml

这个文件中的 android:icon="@mipmap/ic_launcher_foreground" 需要替换成 你自己的 图标或者修改为系统默认的图标才行，不然会报错

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

    <application android:allowBackup="true" android:icon="@mipmap/ic_launcher_foreground" android:label="@string/app_name" android:roundIcon="@mipmap/ic_launcher_round" android:supportsRtl="true" android:theme="@style/AppTheme">
