Use the Zebra Printer SDK -

https://www.zebra.com/us/en/products/software/barcode-printers/link-os/link-os-sdk.html

This SDK has Bluetooth connection classes, status, and methods to send ZPL.

The following example shows much of what you want to do. Replace the looper usage with the newer threading methods.

The issue seems to be related to poor handling of HttpURLConnection object. There are issues in the downloadUrl() method implementation in the class DownloadWebpageTask, which may be relevant to the queries 1-3, the variable responseCode is never used.

If the response is not HttpURLConnection.HTTP_OK , try reconnecting ( or till a custom timeout) or return a null string. On slow internet or bad connection, the response will not be HttpURLConnection.HTTP_OK, hence trying to reference the json-object may lead to undefined behavior.

Can AWS Amplify do MQTT?

Asked 2020-Jul-10 at 21:38

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

Yes, you can use the AWS IoT SDK for Android. The AWS IoT SDK uses MQTT as its messaging transport. An example use is here. The source code is here. Here is the artifact in maven.

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

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.
I want to achieve this without creating cognito user.
Is it possible to make this happen without pool ID ?

The second argument to the KinesisVideoAndroidClientFactory is a generic AWSCredentialsProvider.

The AWSMobileClient, which provides authentication via Cognito, is one example of an AWSCredentialsProvider.

However, there are other implementations of the AWSCredentialsProvider. One of the simplest possible solutions is to use a StaticCredentialsProvider, to provide some BasicAWSCredentials.

In Kotlin:

QUESTION

Use cognito login instead of certificates to authenticate and subscribe to aws IoT MQTT topics?

Asked 2020-May-06 at 18:39

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?

...

ANSWER

Answered 2020-May-06 at 18:39

Short answer, Yes, it is possible. To do that you should do the following:

Create Cognito user pool. User Pool ID and App client id will be used in the next step. You can find more information here.
Create Cognito Identity pool. Under Authentication Providers you should give User Pool ID and App client id, more information here. When you create this, it will create two Roles for Authenticated and Unauthenticated users in IAM. You should add IoT access permissions (Connect, Publish, Subscribe and Receive) to those roles.
On client side (your App), after choosing your preferred AWS SDK (Android, iOS, React, JS, etc.) and configuring User pool ID, Identity pool and App client ID you should first authenticate the user by sending the user information (usually Email/Username and Password) to the Cognito user pool. In return, you will get some tokens.
Among those IdToken (JWT) will be sent to the Identity pool and in return you will get User Identity ID along with credentials (accessKeyId, secretAccessKey, sessionToken) needed to access AWS other services like IoT.
Last step would be using aws-iot-sdk for your App along with those credentials to publish and subscribe to your IoT topics. You can find more information about aws-iot-sdk here.

QUESTION

Android LibVLC, take snapshot of RTSP stream without TextureView

Asked 2020-Jan-06 at 03:01

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.

The question is how can I create a snapshot (either into file, or into buffer) on Android with libVLC, without using TextureView? Update1:

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:

Answered 2020-Jan-06 at 03:01

A few ways to go about this...

Here's a crossplatform thumbnailer example using libvlc https://code.videolan.org/mfkl/libvlcsharp-samples/blob/master/PreviewThumbnailExtractor.Skia/Program.cs It should work on Android without much editing since it doesn't use any OS specific feature in the script. Should be able to translate it to Java/Kotlin as well I guess.
There is a libvlc function that allows to take snapshot. Just go the time you want and call it. https://www.videolan.org/developers/vlc/doc/doxygen/html/group__libvlc__video.html#ga9b0a3870ce962aa0358050b2d5a59143
In VLC Android, the medialibrary now manages thumbnails.
LibVLC 4 now bundles a thumbnailer https://github.com/videolan/vlc/blob/d40eb012b10cc355ea9ad7a13eaf494b8e826d78/include/vlc/libvlc_media.h#L845
