Answer 1

Use InputConnectionCompat something like this:

private void commitImage(Uri contentUri) {
    InputContentInfoCompat inputContentInfo = new InputContentInfoCompat(contentUri, new ClipDescription("", new String[]{"image/jpg"}), null);
    InputConnection inputConnection = getCurrentInputConnection();
    EditorInfo editorInfo = getCurrentInputEditorInfo();
    int flags = 0;
    if (android.os.Build.VERSION.SDK_INT >= 25) {
        flags |= InputConnectionCompat.INPUT_CONTENT_GRANT_READ_URI_PERMISSION;
    }
    InputConnectionCompat.commitContent(inputConnection, editorInfo, inputContentInfo, flags, null);
}

on kotlin:

private fun commitImage(contentUri: Uri) {
    val inputContentInfo =
        InputContentInfoCompat(contentUri, ClipDescription("", arrayOf("image/jpg")), null)
    val inputConnection = currentInputConnection
    val editorInfo = currentInputEditorInfo
    var flags = 0
    if (Build.VERSION.SDK_INT >= 25) {
        flags = flags or InputConnectionCompat.INPUT_CONTENT_GRANT_READ_URI_PERMISSION
    }
    InputConnectionCompat.commitContent(
        inputConnection,editorInfo,inputContentInfo,flags,null)
}

In short, it's not possible. I had a job awhile back where I was trying to essentially do that exact thing, and I found that it's only possible to pass images if they are unicode characters. I further found that I could only pass certain ones on pre-Lollipop devices, because they didn't have the full set.

If you're only looking to deploy to Lollipop+ and your images are unicode, you can use getCurrentInputConnection().commitText("\\u2602", 1); for an umbrella like this ☂
