Adreno Profiler
高通的GPU调试工具，使用mono开发，特别介绍一下，这是唯一可以比较方便导出渲染资源的工具，可以在不破解的情况下扒取游戏贴图，模型，shader等资源。不过导出的资源会丢失一些信息需要工具还原。

Snapdragon Profiler
https://developer.qualcomm.com/software/snapdragon-profiler

snapdragon profiler is profiling software that runs on the windows, mac, and linux platforms. it connect with android devices powered by snapdragon processors over USB. snapdragon profiler allows developers to analyze cpu, gpu, dsp, memory, thermal 热量, and network data, so they can find and fix performance bottlenecks.

features and benefits

real-time view makes it easy to correlate system resource usage on a timeline.
a) analyze cpu, gpu, dsp, memory, power, thermal, and network data metrics.
b) selert from over 150 different hardware performance counters in 22 categories.
trace capture mode allows u to visualize kernel and system events on a timeline to analyze low-level system events across the cpu, gpu, and dsp.
a) view cpu scheduling and gpu stage data to see where your application is spending its time
snapshot capture*** mode allows u to capture and debug a rendered frame from any opengl es app.
a) step through and replay a rendered frame draw call-by-draw call
b) view and edit shaders and preview the results on your device
c) view and debug pixel history
d) capture and view gpu metrics per draw call
gpu aips: opengl es 3.1, opengl 2.1 and vulkan 1.0**

Requires a Snapdragon 820 (or later) processor
** Requires Android N (or an Android 6.0 device with a graphics driver that supports Vulkan)
*** Requires a Snapdragon 805 (or later) processor and Android 6.0 (or later)

这个注册，需要一天，我找了别人下载了给我：
同时安装的时候，需要安装gtk，所以下载好之后先安装：
在这里插入图片描述
C:\Program Files (x86)\GtkSharp\2.12
官方下载地址: https://developer.qualcomm.com/software/snapdragon-profiler

安装时会要求安装这个 gtk-sharp-2.12.44.msi - https://dl.xamarin.com/GTKforWindows/Windows/gtk-sharp-2.12.44.msi

这两个软件安装好之后，就是打包一个android的包了：
具体参考：https://blog.youkuaiyun.com/unity_http/article/details/79929454

1、新建工程
在这里插入图片描述

D:\Program Files\Unity2018\Editor\Data\PlaybackEngines\AndroidPlayer\Variations\mono\Release\Classes

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="demo.xiaoming.com.xiaominglib">
      <application
        android:allowBackup="true"
        android:label="@string/app_name"
        android:supportsRtl="true">
            <activity android:name=".MainActivity2" android:label="@string/app_name">
                <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>
            </activity>
        </application>
</manifest>

下面是使用这个jar包：
新建unity项目，我这里使用的是unty2018

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class NewBehaviourScript : MonoBehaviour
{
    public Text text;
    private AndroidJavaClass unity;

    private void Start()
    {
        if (unity == null)
        {
            unity = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        }
    }
    public void Add()
    {
        AndroidJavaObject currentActivity = unity.GetStatic<AndroidJavaObject>("currentActivity");
        int a = currentActivity.Call<int>("Add", 2, 5);
        text.text = a.ToString();
        Debug.LogError("add = " + a);
    }
}
