android-app | example Android application , which is based on Rails | Android library

I tried connecting Firebase with my app and this error came

This is my build.gradle (Project)

I would like to add multiple icons with shortcuts on home screen. For example i would like to add two icons with specific shortcuts:

1. First icon-> Open Google.com in Google Chrome
2. Second icon -> Open YoutubeApp

I don't want to use shortcuts with one default icon, like in this example: enter link description here

I would like to generate separately icon for specific shortcut.

Is it possible at all?

I would like to run an Android-app with two services using 'service' tag.

I am following this AWS Android CI/CD pipeline guide. It builds is successfully, but artifacts are not uploaded on S3.

My buildspec.yml:

I am doing this course on Coursera, and in the 3rd week 1st block video, the instructor has us write the following line of code:

In our android app, I am unable to register the app for enrollment. Everything is set up according to this sample "https://github.com/msintuneappsdk/Taskr-Sample-Intune-Android-App" but still i am always receiving"AUTHORIZATION_NEEDED" error code when i call registerAccountForMAM().

I am using MSAL with intune SDK and the app is registered as multi tenant.

I have a simple browser app. It loads some IP and displays it using WebView. I want to access the source code of the loaded URL and store into Android string so I can use it.

For an example :

Suppose it is loaded 10.0.0.1 and the webpage shows this.

So, I want to store that "HELLO THERE". And further want to process if string is equal to "HELLO THERE", a toast will be shown.

I managed to load the URL, and I know how to make Toast. The problem is, I am not able to store that "HELLO THERE" in string.

Solution Tried :

1. http://blog.weinigel.se/2014/03/05/getting-html-source-from-android-webview.html
2. Is there a way to get the HTML in a webview in an Android app?
3. How I get page source from WebView?

I have tried all of above solutions. But, none worked. It would be great if I get the answer using specific scenario of mine.

I stumbled upon this problem some time ago and made this post: Is my QML android application running on software and how can I fix this?.

The answers suggested that the app is actually being rendered on GPU and I just need to optimize my code with a profiler but I didn't find any kind of complicated bindings or anything that could be significantly optimized. But I did notice that shadows are what causes all the lags. I decided to experiment with it and created a very simple program: two spinning rectangles with a shadow applied to both of them.

Here's the code:

First of all, this question is NOT about how I can prevent the app from being killed. Actually I want it to be killed.

Now the problem. My application connects to a BLE devices and I want the connection to be maintained when the app is in the background, but I don't want it to be maintained when the user removes the app from recent apps.

I implemented a Service that I run when the connection is started, which I send to foreground when app goes to background. I tried both with only bound service which is destroyed when the activity is destoyed, and also with started service which I stop in onTaskRemoved. Both cases have the same issue.

The problem is that when I wasn't using the service and removed the app from recents, it got properly killed and the BLE connection was being ended, but when I started using service, the application process seems to be still active and the BLE connection is persisted.

I did some investigation using Android Studio profiler, and I can see that after I removed the app from recents, there is no Activity and there is no Service running in my app, but the Application object is still there.

Leakanary dosn't report any memory leaks either.

It seems that it may be similar to this issue, but there was no answer. It is also a bit similar to this issue, but I use clean Android, not cordova.

I investigated the Logcat and in the flow without service I get:
