| How long did it take for you all to finish your associate android developer certificate exam ? Posted: 13 Nov 2021 10:40 PM PST I'm planning to write it today in sometime. I've heard and read that it is of 8 hours but wanted to know if 8 hours is sufficient or barely enough to finish the exam ? [link] [comments] | ||
| Posted: 13 Nov 2021 11:55 PM PST hello everyone I started learning Android programming about a month ago I can make some simple applications in the Java language, but I find it difficult to find some of the tasks that I program So can you guide me to some site that give tasks for beginners I want to know what to do if my level is improving or not [link] [comments] | ||
| 16" Macbook Pro M1 Pro Testing Posted: 13 Nov 2021 12:31 PM PST For those interested in the new Macbook Pro, here are the Android Studio results I am seeing with the 16" M1 Pro. The following build times are the best of three, using the --offline flag to ensure network connections aren't making a difference. Rocket Player release build times
Boy does this laptop feel fast. My only regret is not getting the M1 Max version. I don't think Android Studio will perform any better on an M1 Max, but I no longer want to use my iMac, and the M1 Max can drive three monitors instead of just two. But losing a monitor is worth it to have something this fast to developer on. (I did not try an emulator. I don't use them.) [link] [comments] | ||
| Do we really need to use Dependency Injection Framework? Posted: 13 Nov 2021 05:55 PM PST I understand what DI is but the examples using framework like Hilt looks complicated for me. Can anyone share example of how code becomes simpler using Hilt & compare it to code without Hilt? [link] [comments] | ||
| Is Android canvas holder.lockCanvas blocking UI thread beginning Android SDK 30? Posted: 14 Nov 2021 05:51 AM PST I have a design that works perfectly fine in Android SDK 29 where my experiment to have some delay (using Sleep) in canvas holder.lockCanvas doesn't block the UI thread. (I just want to experiment and see that the UI thread is not blocked by the slow processing within the canvas drawing. ) However, in Android SDK 30 and later, this is no longer true, even though I explicitly send the canvas drawing background. Has something changed in Android SDK 30 and later or is this a bug? The issue (with actual sample design provided) is further described in https://stackoverflow.com/questions/69963569/why-in-sdk-30-and-later-the-background-thread-sleep-function-within-holder-lock.

| The fastest way to save Bitmap as a file. Posted: 14 Nov 2021 02:34 AM PST Hi, I hope you're doing well, I'm following these steps to make some changes to a video : 1 - Extraction: extract all frames (frame_1.jpg, frame_2.jpg ...) from the video using FFmpeg 2 - Apply changes: getting the bitmap from a file (extracted frame → bitmap), then applying the change to each bitmap. 3 - Making video file: since FFmpeg works with the file path, I saved each processed frame as a file and save it to a folder, when all frames were processed, I create a new video file using those processed frames. Current issue : This process takes too long, e.g. a 5seconds video may take up to 2 min to finish processing. After some investigating, I found that the save bitmap as file process is the reason why the process takes a long time to finish. I tried to decrease the quality and use JPEG instead of PNG, but the process still take too long. Question : Is there any faster way to save the bitmap as a file? Thank you. [link] [comments] | ||
| How to learn Android development for an iOS developer? Posted: 13 Nov 2021 04:51 PM PST I'm looking to get into Android development and I'm trying to find a course to help me with it. I'm not new to programming so I don't need something that goes very slow and explains the basics of coding. Does anyone know of any courses on Udemy or elsewhere that can help me?

| How do you reverse engineer or make a clone of an Android app? Posted: 14 Nov 2021 06:32 AM PST I saw a Christian community app called YouVersion Bible app which is awesome with some functionality, features I like and obviously it is in English. I want to make an app which is same as this but everything will be in my local language (Gujarati). So instead of making everything from scratch is it possible to take the existing app and tweak its code? BTW this project will be completely funded by me and no monetization whatsoever. Will there be copyright issues if I make an app like them? I don't want to copy someone else work I just want to contribute to our community here by making a app in our local language. So yeah, that is my idea. Any suggestions or thoughts are welcome. Thanks. [link] [comments] | ||
| Is RxBus or similar event delivery methods still a good practice? Posted: 13 Nov 2021 01:54 PM PST I've seen some RxBus implementations in pretty old apps, usually built with MVP architecture, but now I'm surfing the Internet to learn a little bit more about event-delivery methods and I'm kinda confused. Why isn't the approach of asynchronous uncontrollable bus deprecated or restricted? Doesn't it violate principles of good app architecture? Sending events directly from Receiver/Service to Service or Activity, which doesn't even active at the moment looks like inappropriate way, quickly destroying any sort of architecture and bringing implicitly strongly connected parts of code? Please, share your opinion with me, what are real use cases, when it's okay to use "cross-component" event delivery? Is it better, than delegation/callbacks? Any information about event-sharing between different app components is much appreciated. Thanks. [link] [comments] | ||

| Increase performance when device is running only one App Posted: 13 Nov 2021 08:56 AM PST I'm developing an App, which runs on a Smartphone, which is mounted on top of a Rover. The App is responsible for real-time object detection. Therefore, it may do some heavy computation. I can't ditch Bluetooth and Internet (LTE), because the app needs them. It needs the Camera as well. I want to squeeze every last drop of performance out of the hardware. It only needs to run the App. Nothing else. What I already did:
Are there any tricks to boost performance even more? Thanks in advance [link] [comments] |
