Let's take a look at the effect first. . .
upper code
AppUpdate.cs
using System.Collections;
using System.IO;
using UnityEngine;
using System;
public class AppUpdate: MonoBehaviour

}
catch (Exception e)

Put the following UTool.java code into Unity's Plugins/Android/ folder
UTool.java

}
private Context context;
public void Init(Context context)
{
Toast.makeText(context, "init", Toast.LENGTH_LONG).show();
this.context = context;
}
public void installApk(String apkFullPath)
{
try
{
File file = new File(apkFullPath);
if (null == file){
return;
}
if (!file.exists()){
return;
}
Intent intent = new Intent(Intent.ACTION_VIEW);
Uri apkUri =null;
if(Build.VERSION.SDK_INT>=24)
{
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
apkUri = FileProvider.getUriForFile(context, context.getPackageName()+".fileprovider", file);
//intent.setDataAndType(apkUri, "application/vnd.android.package-archive");
}else{
apkUri = Uri.fromFile(file);
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
}
intent.setDataAndType(apkUri, "application/vnd.android.package-archive");
Toast.makeText(context, apkUri.getPath(), Toast.LENGTH_LONG).show();
context.startActivity(intent);
}
catch (Exception e)
{
Toast.makeText(context, e.getMessage(), Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
}
The jar package android-support-v4.jar that android needs to use
is placed in the Plugins/Android/libs/ folder of Unity
The android file configuration AndroidManifest.xml
is placed in the Plugins/Android/ folder of Unity
and com.xxx.xxx is set as the package name of your project
<?xml version="1.0" encoding="utf-8"?>
