    How to get video for processing with openCV (camera2)

    Posted: 05 Jan 2020 07:37 AM PST

    I want to get video and process it in real time. I think there's some way to pipe the preview to somewhere other than the screen, but I haven't found any guide to help me.

    Also if anyone has a good guide for camera2, figuring it out by reading documentation has been a less than enjoyable experience.

    How to cast sound files contained in assets directory?

    Posted: 05 Jan 2020 05:55 AM PST

    My apps contains some mp3 file stored in the assets directory, I want to cast them programmatically but the MediaInfo.Builder seems to work only with urls, I've found some posts suggesting to install a web server and cast from it but I don't like this solution, I'm missing some API or it's really so hard to stream a simple file to cast programmatically?

    Need a way to record intermittent video/audio

    Posted: 05 Jan 2020 04:00 AM PST

    Need a way to record intermittent video/audio

    Hi developer friends,

    I'm currently developing an app and I'm a bit stuck. I'm absolutely non familiar with this thing called "asking for help" but, it will save me a real deal of time (>10y developing and it's the first or second time I ask smth).

    So, please help me reddit \o/

    In Java, I have four data streams, all in real time and all can be interrupted and resumed. Two are audio and two video. I need to record them in a single file.

    Example :

    https://preview.redd.it/kythxgvd7y841.png?width=936&format=png&auto=webp&s=748f2e3fd82cad2459686e0cd4f9bf4ca3ebb80a

    I could use the mp4 multitrack solution proposed in the native muxer doc (even if the android +26 is a big penalty) but I don't know if it supports a stream to be interrupted in the middle while "preserving the absence of data".

    Is there an existing way to do it ? I prefer to avoid creating my own.

    Admob strange stats

    Posted: 04 Jan 2020 12:32 PM PST

    Hi all,

    I recently launched an app with integrated admob and I see strange numbers that dont really correspond with the numbers of installs...

    For example, an ad is requested after 2 minutes into the game, but the ad itself is shown after match end (1 match can be anywhere between 2-30 minutes depending on match rules). But in any case, there should be at least 1 request per every app start (provided the users kept the app open for at least 2 mins) right?

    For example yesterday reports shows 188 downloads and admob reports only 16 requests?!

    For last 7 days I have 466 downloads with only 81 request and 32 impressions with 100% match rate.

    Could anyone please advise if this is normal?

    I am new to this but from my point of view:
    A) users use adblockers or close my app sooner than 2 minutes after startup etc.
    B) something is wrong with admob

    AFAIK I have everything set up correctly, I triple checked every setting. When I asked few of my friends from different countries to try the app I can see the reports are fine in those cases...

    I am using google ads campaign with very cheap bids and 80% users are from India in case it would mean anything...

    Also, I can see that most users actually opened the app after installation. For the last 7 days, Unity analytics reports 420 sessions...

    Thanks for any help!

    Learning Android (Kotlin), looking for some code review

    Posted: 04 Jan 2020 12:23 PM PST

    Any guidance would be very much appreciated. Here is the repository:
    https://github.com/kav0rka/dndSpellTracker

    It is an app for people who play Dungeons and Dragons. Basically, it allows the user to track their spells and abilities while they play and across game sessions. It is not a full character creator but if you punch in your characters info it will auto generate the spells and abilities you have access to.

    I am "attempting" to use the MVVM pattern but I am sure I went astray at some parts. I am using Room to help with the database.

    Currently there are some things on the view models that are not being used, I have been thinking on some refactoring but wanted to get some feedback before going into it (and potentially going in the wrong direction).

    Thank you again for any feedback you might have :)

    Common location for shared files between apps?

    Posted: 04 Jan 2020 09:30 AM PST

    I'm looking to share files between a demo version of my app and the full version, so that the full version (once purchased) can access the save from the demo game and carry over the user's progress. I've been trying to get the AndroidX FileProvider system set up, but I'm having a lot of trouble getting it working in my project (which is made in Unity, not so much using Android Studio). This had lead me to wonder, does there exist some storage location which all apps have read/write access to on Android devices? The save file doesn't contain any sensitive data, so I wouldn't mind skipping out on the security provided by the FileProvider system, in exchange for the ease of setup between my apps.
