android-samples | Samples demonstrating how to use Maps SDK for Android | Learning library

I'm trying to understand how I can integrate Google Drive API in my Android App(using Android Studio). I have tried the example app that I found here(https://github.com/googleworkspace/android-samples/tree/master/drive/deprecation) but after Google API console configuration my app stucks in an infinite loop when I choose an Account. Why? Where is the problem? I tried also with this(https://youtu.be/5bSEIQYJzKs) tutorial but I have the same problem. Here my build.gradle specific lines:

I) Below is code for parsing data async from google sheet and works fine as long as the internet speed is good but crashes on slow speed. How to address this? I have fixed for no internet.

II) If the google sheet is opened for update ( one a row at a time), the system crashes on trying to open. How can I skip the rows which are not assessible ( or updating) ?

III) Is there any way to find time when the google sheet was last updated ?

IV) How to tell google maps not to open the map till the parsing is done?

On the github page https://github.com/aws-amplify/aws-sdk-android it says:

For new projects, we recommend interacting with AWS using the Amplify Framework.

On the Amplify Framework page about JS developement (https://docs.amplify.aws/lib/q/platform/js), there's a library called PubSub that should do MQTT connection.

But if I switch to Android developement (https://docs.amplify.aws/lib/q/platform/android), that option is not there anymore.

Is there a way to use MQTT with Amplify and GraphQL? Or I need to refer to the android aws sdk and more specifically to this example: https://github.com/awslabs/aws-sdk-android-samples/blob/main/AndroidPubSub/src/com/amazonaws/demo/androidpubsub/PubSubActivity.java

I am using Amazon KVS Video Streaming Service. I need help in below 2 points.

1. I know that vedio streaming can be done in 2 ways. First using web RTC and second using KVS video Streaming. I want to know how can it be done using KVS video Streaming? I have Access Key ID and Secret Access Key.
2. I want to achieve this without creating cognito user.
3. Is it possible to make this happen without pool ID ?

I am following below reference.

• https://docs.aws.amazon.com/kinesisvideostreams/latest/dg/producersdk-android-downloadcode.html
• https://github.com/awslabs/aws-sdk-android-samples/tree/main/AmazonKinesisVideoDemoApp

I'm new to learning AWS and I'm trying to figure out if my use-case is possible. I want to create a mobile app where the user can login (email/facebook/google etc.) and then subscribe to a few MQTT topics on aws IoT to receive realtime sensor data for a gardening system. There are many tutorials on AWS that show you how to do this (prime example: https://github.com/awslabs/aws-sdk-android-samples/blob/master/AndroidPubSub/README.md)

but all of them require you to download certificates, insert app IDs, secret keys etc. in the code/keystore itself. I'd really like to avoid all of this and just use the login as all the authorization you would need to subscribe to these topics.

is this possible? or do I need to build some custom system?

Found sample on Sample-Bridgefy, but not able to run successfully!

Consider using libVLC for Android, based on the official recommended way.

I went through the compilation process without problems (but took some time).

I'd like to have the snapshot functionality, but I've found some very old (2-3 years old) threads around which states that this feature is still not available (2016) at least "not out of the box' by this thread (2014).

Snapshot functionality is available on other platforms.

Also there are some solutions where they switch from SurfaceView to TextureView.

However I prefer sticking to SurfaceView as TextureView brings some performance drawbacks (according to this topic).

Also on an official android page it's stated:

In API 24 and higher, it's recommended to implement SurfaceView instead of TextureView.

In 2014 there were only 2 dependecies of the snapshot function based on the thread I've mentioned earlier:

• enabling sout module
• enabling png as encoder

When looking the "VLC-Android" repository of VideoLAN, there is a file responsible for building libVLC.

In line 396, sout module seems to be enabled by default.

Before compilation I've enabled png as encoder in vlc/contrib/src/ffmpeg/rules.mak as pointed out in the forum.

However there is still no function related to snapshot in either org.videolan.libvlc.MediaPlayer or in org.videolan.libvlc.VLCVideoLayout.

Fact1: Found the reason on why it's unavailable on Android. In VLC's core source tree, in file lib/video.c on line 145 there is the snapshot function with a massive FIXME warning:
