Android: How to convert Bitmap to Uri?

UriToBitmap.md

fun getImageUriFromBitmap(context: Context, bitmap: Bitmap): Uri{
    val bytes = ByteArrayOutputStream()
    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bytes)
    val path = MediaStore.Images.Media.insertImage(context.contentResolver, bitmap, "Title", null)
    return Uri.parse(path.toString())
 }

it's giving me a black color instead of transparent, I've changed JPG to PNG but nothing works

I've updated the Kotling version, can you please try it? @Mouadabdelghafouraitali

I am getting the crash for this

Hello @shivayogih,
What is the crash?

work for me

giving null not working MediaStore.Images.Media.insertImage(context.contentResolver, bitmap, "Title", null) this is deprecated any other solution for this ?

With this problem I was trying but cannot resolve problem so I think you can try using this code to open camera val value = ContentValues() value.put(MediaStore.Images.Media.TITLE, "New Picture") value.put(MediaStore.Images.Media.DESCRIPTION, "From the camera") imageURI = currentActivity.contentResolver.insert( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, value ) val intent = Intent(MediaStore.ACTION_IMAGE_CAPTURE) intent.putExtra(MediaStore.EXTRA_OUTPUT, imageURI) startActivityForResult(intent, CAMERA_REQUEST) We will have uri is imageURI and not need get from Intent. And if you want get bitmap from uri you can using this code mBitmap = BitmapFactory.decodeStream( activity!!.contentResolver.openInputStream(imageURI!!) I try and success. I hope this code can help you. Vào Th 4, 19 thg 5, 2021 vào lúc 19:22 Anil Kumar < ***@***.***> đã viết:

does anyone come out with the solution ??
if yes, please share with all it will be of great help

I ended up using this useful lib : implementation 'com.blankj:utilcodex:1.30.6'

ImageUtils.save(bitmap, cached_path, Bitmap.CompressFormat.JPEG);
Uri bitmap2Uri = UriUtils.file2Uri(FileUtils.getFileByPath(cached_path));

cached_path ? how to define it

no one had solved the problem?

@MUhammadasadnazar what is the problem that you have?

I want to convert bitmap to image_uri but the app is going to crash with error path is null

There's no way to convert a Bitmap to URI, you should store the bitmap as a file in the user device, then use that file to get the URI, once you're finishing with it, remove it, I'm using the following code to achieve that :

First, I save the bitmap as a file :

cachedPath = "CREATE A FOLDER AND ADD (.) BEFORE THE FOLDER NAME TO MAKE IT INVISIABLE TO THE USER"
ImageUtils.save(YOUR_BITMAP, cachedPath, Bitmap.CompressFormat.PNG);

Once the file is saved, you can get the URI like that :

Uri uri = UriUtils.file2Uri(FileUtils.getFileByPath(cachedPath));

I'm using implementation 'com.blankj:utilcodex:1.30.6' to make things easier for me.

let me just try thanks

val path = MediaStore.Images.Media.insertImage([email protected], result ,"Tittle",null)
val uri = Uri.parse(path.toString())

java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String java.lang.String.toString()' on a null object reference

got error in the MediaStore.Images.Media.insertImage([email protected], result ,"Tittle",null) is null. Whats really weird is that it used to work in my exercise app. when I try making another app, it worked for a while then it crash(I didn't do anything that disturb the code). and when I try my old exercise app that used to work in case I changed something in my new app that caused the crash, my old app crash also(I didn't even do anything to my old app) and with the same error

There is a problem with the storage when using that implementation - it works fine until you have 32 (2^5) pictures taken from the app saved in your gallery, that's when it crashes.
if you delete one photo you taken in the app from the gallery you can take another one in the app before it crashes again - until you get to 32 again.
Don't know the reason it happens though.
