how to add custom image as emoji in android InputMethodService. i have tried using
ImageGetter imageGetter = new ImageGetter() {
public Drawable getDrawable(String source) {
StringTokenizer st = new StringTokenizer(str, ".");
Drawable d = new BitmapDrawable(getResources(),emoticons[Integer.parseInt(st.nextToken()) - 1]);
d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
return d;
}
};
Spanned cs = Html.fromHtml("<img src ='"+ str +"'/>", imageGetter, null);
getCurrentInputConnection().commitText(cs,1);
but only getting 
a obj text image.
is there any way to add custom emoji to message(whatsapp /twitter) in android
Edit :
in my application if i type hello using my custom keyboard i have to insert a custom hello picture in edit field for every app installed in phone.
can it achieved ?
Edit : 2
i have checked it using convert mage to base64 also but nothing happen with Tag
ImageGetter imageGetter = new ImageGetter() {
@Override
public Drawable getDrawable(String source) {
byte [] encodeByte=Base64.decode("iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==",Base64.DEFAULT);
Bitmap bitmap=BitmapFactory.decodeByteArray(encodeByte, 0, encodeByte.length);
Drawable d = new BitmapDrawable(bitmap);
Log.e("Chk", "Height : "+d.getIntrinsicHeight());
Log.e("Chk", "Width : " + d.getIntrinsicWidth());
return d;
}
};
Spanned cs = Html.fromHtml("<img src='data:image/png;base64, iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg=='/>", imageGetter,null);
Log.e("Chk", "12 : " + 12);
getCurrentInputConnection().setComposingText(cs,1);
Edit : 3
