Android Framework - Introduction to HIDL in Android

Hi All,
In this video I have explained the concept of HIDL in android

[@jeraldtg5369]

One update, as per my understanding, c/c++ have many libraries so it is not avoidable.
C/cpp is fast, memory efficient etc.
Java is easy to learn compared to c/cpp, also jni support c/cpp by default. In java gc doesn't clear memory always. So java used by google because it's easy and have more libraries tutorial etc.
Google created kotlin as oracle filed for royalty. Now case is in favor of google so android is supporting mainly c/cpp/java/kotlin
Python has much popularity, larger library but is not supported officially. It may be because of it's performance issues.

Hi Dimple your videos are great 👍, I'm also learning AOSP. How you got such deep knowledge? I know it's come from experience & exploring but if there is any resources which you can share that will be very helpful.
thank you

[@dimples_android_geek]

Thank you very much .. no particular resource in such .. I refer to developer.android.com

Hi Dimple, Thanks for posting video like this. Its very useful for me. I have an issue in hwBinder for "null pointer dereference" in AOSP 10. Its reason for using HIDL instead of AIDL?

[@dimples_android_geek]

Thank you, no using AIDL is not mandatory, only on your need basis you can switch . This error will not have anything to do with IDL/AIDL. Need to check from your code end

[@My_Name_Is_Prashant]

Correction required ?
You said HIDL is deprecated and replaced by aidl..

[@dimples_android_geek]

From Oreo onwards HIDL was introduced.. but now Google is replacing it with AIDL .. so from A11 onwards AIDL will be used

[@My_Name_Is_Prashant]

@@dimples_android_geek ohh great..
Thank you..
We need to know only aidl for ipc 😍

[@ajaykeshri971]

Hi @Dimple S, Do you have any video or library to implement local profile assistants (LPAs) on eSIM-enabled Android devices

[@dimples_android_geek]

Sorry I don't have idea about eSIM framework

[@cid007007]

I have doubt If hidl will be replace by aidl then OTA from A10 to A11 will be possible Without any issue ?

[@dimples_android_geek]

I need to understand it as its new feature ... Will let you know

[@amitchaturvedi2246]

THANK YOU .

Hi dimple

[@dimples_android_geek]

Hi

I think HAL is replaced by HIDL

[@dimples_android_geek]

HIDL is an interface for existing HAL
