Answer 1

I faced the same issue and nothing worked. But finally after 3 hours it worked.

Solution: I found that It works fine until we delete that image from our image gallery. After that It starts returning null. But suddenly I tried changing title and description name and it worked like a charm.

So I've added a date with the title and description of bitmap. In case, user deletes bitmap manually from file manager. Still It works.

  private fun insertImage(cr: ContentResolver,
        source: Bitmap?,
        title: String,
        description: String
    ): String? {

        val sdf = SimpleDateFormat("MM-dd-yyyy-hh.mm.ss.SSS.a", Locale.US)
        val date=sdf.format(Date())

        val values = ContentValues()
        values.put(Images.Media.TITLE, title)
        values.put(Images.Media.DISPLAY_NAME, title+date)
        values.put(Images.Media.DESCRIPTION, description+date)
        values.put(Images.Media.MIME_TYPE, "image/jpeg")
        // Add the date meta data to ensure the image is added at the front of the gallery
        values.put(Images.Media.DATE_ADDED, System.currentTimeMillis() / 1000)
        values.put(Images.Media.DATE_TAKEN, System.currentTimeMillis())

        var url: Uri? = null
        var stringUrl: String? = null    /* value to be returned */

        try {
            url = cr.insert(Images.Media.EXTERNAL_CONTENT_URI, values)

            if (source != null) {
                val imageOut = cr.openOutputStream(url!!)
                try {
                    source.compress(Bitmap.CompressFormat.JPEG, 50, imageOut)
                } finally {
                    imageOut!!.close()
                }


            } else {
                cr.delete(url!!, null, null)
                url = null
            }
        } catch (e: Exception) {
            if (url != null) {
                cr.delete(url, null, null)
                url = null
            }
        }

        if (url != null) {
            stringUrl = url.toString()
        }

        return stringUrl
    }

I Implemented to share news bitmap in this app and it's working fine. Enjoy!
