Our Purpose

All for users, make users getting the best experience!

Introduction

Xiaomi Application Accelerator (MiSpeed) provides developers with the interface to apply for system resources,
which can improve the performance of developers in key application scenarios and enhance the user experience.

Our Advantages

• Lightweight Access
  Accessing through JAR file, the size is only a few KB, which will not burden developers' applications.
• Fast System Communication
  Communicate with the system layer directly through binder, request system resources, fast and efficient.
• Scenario Customization
  Provide different levels of system resources in different scenarios.

Access Note

Applying for debugging permission

Please provide the following information and send it to [email protected] to apply for debugging permission.
Subject：xx Company，Applying for MiSpeed debugging permission。

We will reply you with an authentication code for debugging.

Note: What is VAID, how to get it?

1. VAID means Vender Anonymous Device ID
2. Refer http://msa-alliance.cn/col.jsp?id=120
3. You can refer to the example in TestMiBridge. (Testing getVAID)

APIs

Permission apis

1. boolean checkDebugPermission(Context context, String pkg, int uid, String auth_key)
   Description：Check whether the application has debugging permission.
   

   parameters：
   context : application context
   pkg : Package Name
   uid : android.os.Process.myUid()
   auth_key : authentication code
   

   return value：
   true : Permission granted
   false : Permission not granted
   

2. boolean checkPermission(String pkg, int uid)
   Description：Check whether the application has formal permission，please refer 3.Applying for fromal permission
   After obtaining the formal permission, use this interface to check the permission without using the authentication code.
   

   parameters：
   pkg : Package Name
   uid : android.os.Process.myUid()
   

   return value：
   true: Permission granted
   false: Permission not granted
   

APIs for request system resouce

3. int requestCpuHighFreq(int uid, int level, int timeoutms)
   Description： Reqeust CPU frequency
   

   parameters：
   uid : android.os.Process.myUid()
   level : Expected cpu frequency level，system will set different CPU frequency according to different models
   

   Level	Explanation (take Xiaomi 8 as an example)
   1	Level 1 Set the CPU frequency to MAX
   2	Level 2 Set the CPU frequency to higher example：Xiaomi 8, Set big core at least 2.2GHz, little core at least 1.5GHz
   3	Level 3 Set the CPU frequency to above normal example：Xiaomi 8, Set big core at least 1.9GHz, little core at least 1.0GHz

   Attention：Please using Level 1 with caution。Level 1 scenarios is limited to 5，
   Level 2 is limited to 20，Level 3 no limits。
   timeoutms : duration
   

   return value：
   0: Success
   -1: Fail
   -2: Permission not granted!
   

4. int cancelCpuHighFreq(int uid)
   Description：Cancle cpu frequency request
   

   parameters：
   uid : android.os.Process.myUid()
   

   return value：
   0: Success
   -1: Fail
   -2: Permission not granted!
   

5. int requestThreadPriority(int uid, int req_tid, int timeoutms)
   Description：Request thread for higher priority, running in big core.
   

   parameters：
   uid : android.os.Process.myUid()
   req_tid : thread id
   timeoutms : duration
   

   return value：
   0: Success
   -1: Fail
   -2: Permission not granted!
   

6. int cancelThreadPriority (int uid, int req_tid)
   Description：Cancel request
   

   parameters：
   uid : android.os.Process.myUid()
   req_tid : thread id
   

   return value:
   0: Success
   -1: Fail
   -2: Permission not granted!
   

Applying for fromal permission

Please provide the following information and send it to [email protected] to apply for formal permission.
Subject：xx Company，Applying for MiSpeed formal permission。
Note：To apply for formal permission,relevant business agreements need to be signed.
1. APIs using scenarios

2. Performance Test

Note：We will also do performance test according to the scenarios provided by you.

3. Power consumption test

Note：We will also do power consumption test according to the scenarios provided by you.

More cooperation

More APIs will be supported in the future
requestGpuHighFreq，requestIOHighFreq，requestMemory，requestNetwork and so on.

Other supports that can be provided in the future
Provide more support for your application (e.g. memory leak detection), improve the performance of the application, and improve the user satisfaction.
