I want to generate any view of android phone as an image and also share that generated image via whatsapp, skype and mail

Question

Here is my code can anybody suggest me what to do also NOTE: My app only supports from android 6 to 10 devices only so suggest me accordingly

private fun shareInvoice(){

    binding.consLayout1.isDrawingCacheEnabled = true
    binding.consLayout1.buildDrawingCache()
    binding.consLayout1.drawingCacheQuality = View.DRAWING_CACHE_QUALITY_HIGH
    val bitmap:Bitmap = binding.consLayout1.drawingCache

    val sdf = SimpleDateFormat("dd-MM-yyyy hh:mm:ss", Locale.getDefault())
    val root = Environment.getExternalStorageDirectory().absoluteFile
    val file = File(root,"/Pictures")
    val imageName = "ServiceInvoice_${businessName}_${sdf.format(System.currentTimeMillis())}"
    val myFile = File(file,imageName)

    if (myFile.exists()){
        myFile.delete()
    }

    try {
        val fos = FileOutputStream(myFile)
        bitmap.compress(Bitmap.CompressFormat.JPEG,100, fos)
        fos.flush()
        fos.close()
        showMessage("Invoice generated successfully")
        binding.consLayout1.isDrawingCacheEnabled = false

        Log.e("INVOICE TAG", "shareInvoice:$myFile")

    }catch (e:Exception){
        Log.e("FOS TAG", "shareInvoice:$e")
    }
}

Follow the method

private Uri saveImageExternal(Bitmap image) {
    //TODO - Should be processed in another thread
    Uri uri = null;
    try {
        File file = new File(getExternalFilesDir(Environment.DIRECTORY_PICTURES), "to-share.png");
        FileOutputStream stream = new FileOutputStream(file);
        image.compress(Bitmap.CompressFormat.PNG, 90, stream);
        stream.close();
        uri = Uri.fromFile(file);
    } catch (Execption e) {
        Log.d(TAG, "IOException while trying to write file for sharing: " + e.getMessage());
    }
    return uri;
}

private void shareImageUri(Uri uri){
    Intent intent = new Intent(android.content.Intent.ACTION_SEND);
    intent.putExtra(Intent.EXTRA_STREAM, uri);
    intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
    intent.setType("image/png");
    startActivity(intent);
}

So Call

Uri uri  = saveImageExternal(bitmap);
shareImageUri(uri);

Don't Forget to add in manifest and Request The Permission

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" android:maxSdkVersion="18"/>

Hello somnath, Thank you for your valuable reply, So i am using kotlin so getExternalFilesDir() is showing error — Yug Mewada, Nov 02 '22 at 12:53
Use "val file: File = File(context?.getExternalFilesDir(Environment.DIRECTORY_PICTURES), "to-share.png")" — , Nov 02 '22 at 13:12

Here i get the final solution of my question if anybody wants to implement this functionality in their application Thank you people those who posted their suggestion and interest.

This code i have tested in Android version 9,10,11 and 7

private fun scanFile(path: String) {
        try {
            MediaScannerConnection.scanFile(context, arrayOf(path), null) { path, uri ->
                Log.d(
                    "Tag",
                    "Scan finished. You can view the image in the gallery now."
                )
            }
        } catch (e: Exception) {
            e.printStackTrace()
        }
    }

    private fun shareInvoice(){
        val file1 = File(
            context?.getExternalFilesDir(Environment.DIRECTORY_PICTURES)?.path,
            Common.APP_DIRECTORY
        )
        if (!file1.exists()) {
            file1.mkdirs()
        }

        val fileName = file1.absolutePath + "/" + System.currentTimeMillis() + ".jpg"
        val bitmap =  binding.sectionScreenShot.getBitmapFromView()

        try {
            val fos = FileOutputStream(File(fileName))
            bitmap?.compress(Bitmap.CompressFormat.JPEG, 100, fos)
            fos.flush()
            fos.close()
            showMessage(getString(R.string.message_invoice_generated))
            scanFile(fileName)

            val uriForFile = FileProvider.getUriForFile(requireContext(),
                requireContext().applicationContext.packageName + ".provider",
                File(fileName))

            val share `enter code here`= Intent(Intent.ACTION_SEND)
            share.type = "image/jpg"
            share.putExtra(Intent.EXTRA_STREAM, uriForFile)
            lifecycleScope.launch {
                delay(1000)
                startActivity(Intent.createChooser(share, "Share Invoice"))
            }

        } catch (e: Exception) {
            Log.e("FOS TAG", "shareInvoice:$e")
        }
    }

I want to generate any view of android phone as an image and also share that generated image via whatsapp, skype and mail
