I'm new to Android development using Kotlin. I'm trying to practice uploading image from a mobile phone to my app using some methods as codes in the code below. everything works just fine with some processes such as I can select on the imageview then screen popup that can let me select image in my phone. unfortunately, after selecting the image, It shows empty/blank, shows nothing in the app. I've tried to search for help but It didn't work out. Hopefully, I can get a hand here. thanks in advance!

ImageView has a member to load an image from an uri.
And you have an uri data.data.
So use it.

what is new defind for MediaRecorder() not Deprecated ?
give me error
java.lang.NoSuchMethodError: No direct method (Landroid/content/Context;)V in class Landroid/media/MediaRecorder; or its super classes (declaration of 'android.media.MediaRecorder' appears in /system/framework/framework.jar!classes2.dex)
Use an if/else to set the property using the supported constructor:
recorder = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) MediaRecorder(this) else MediaRecorder()
Down the road it is possible Jetpack will add a helper function that would do this for you, something like MediaRecorderCompat.newInstance(this). However, it has been so long I think we can assume they will probably not be adding it.
I used the following script in an app published on the Playstore
fun prepare_audio_and_directories(v : View) {
var tempDir : File
// current_filename = (v.findViewById(R.id.audio_filename_xml) as TextView).text.toString()
current_dir = main?.dir!!
tempDir = current_dir
main?.filenameCompletePath = tempDir?.toPath().toString() + "/" +current_filename + "."+ main?.ext
main?.filename_text = current_filename
Log.d("$TAG:prepare_audio_and_directories:main?.filenameCompletePath=", main?.filenameCompletePath!!
)
Log.d("$TAG:prepare_audio_and_directories:main?.filename_text=", main?.filename_text!!)
Log.d("NoiseSuppressor.isAvailable()=", NoiseSuppressor.isAvailable().toString() )
mediaRecorder = MediaRecorder()
mediaRecorder?.setAudioSource(MediaRecorder.AudioSource.MIC)
mediaRecorder?.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4)
mediaRecorder?.setAudioEncoder(MediaRecorder.AudioEncoder.AAC)
mediaRecorder?.setAudioEncodingBitRate(128000)
mediaRecorder?.setAudioSamplingRate(96000);
mediaRecorder?.setOutputFile(main?.filenameCompletePath)
}
The versions I tested it with are API 28,29,30 and 31.
I have a Galexy S10+ cell phone. In the contacts app, there are preloaded AT&T service numbers. On the internet, I was able to find instructions on how to disable these numbers from loading, but the instructions are for an old cell phone model. So first anyone know how to keep these from loading?
Here is the old http instructions:
https://www.google.com/search?q=samsung+cell+phone+delete+att+contacts+2020&rlz=1C1CHBF_enUS977US977&oq=&aqs=chrome.0.69i59i450l8.27328431j0j15&sourceid=chrome&ie=UTF-8#kpvalbx=_Dbo4Y9nqDf-j5NoPuZGegA8_21
Alternatively, I would like to do this programmatically, but excluding a string such as "AT&T" from the search in my app. So based upon my code, see below, either on the search line on the cell phone or embedded in the code, I need to alter what is contained in the search string "%$p0%" in the code. Any suggestions. Thanks.

Thanks for your help everyone. I have found the answer to my question. Actually what I was looking for is called overlay
viewFinder.overlay.add(tvText)
use the element "elevation" with 2dp
I have done some code which is working fine everywhere except settings app -> accessibility menu or device admin apps menu
I need to display overlay in settings -> accessibility and device admin apps menu
I have a application where i see this type of overlay you can see below image
First image from settings app
Second image from settings app
You can see above second image when i open -> device admin app -> then my app overlay got hidden but another app overlay is still visible I don't know why?
Please help me guys to fix this issue??

First of all in onInitializationSuccess set player instance to a global field. Then Add a onClickListener to listview. After that in onClick method call player.setCue() method with the video id that you want to play. And at the last play the video with player.play().
