How can I check if my device is capable of displaying Emoji images correctly?

I am using Unicode as. On most devices, the images look fine, but on one of my younger devices (android 2.3) they appear as small squares.

Can I check if my device supports emoji? So I can post my apk until I show ugly squares on some devices.

This is a late answer, but I faced a similar problem. I needed to filter through List<String>

and filter out emojis that could not be displayed on the device (i.e. if the device was old and did not support rendering them).

As a result, I used Paint

to measure the width of the text.

Paint mPaint = new Paint();
private boolean emojiRenderable(String emoji) {
    float width = mPaint.measureText(emoji);
    if (width > 7) return true;
    return false;
}


The part is width > 7

especially hackish, I would have expected the value to be 0.0

for unimplemented emoji, but after a few devices I found that the value did indeed range from 3.0

to 6.0

for non-renderable and 12.0

to 15.0

for renderable. Your results may vary, so you can check this. I believe the font size has an effect on the output as well measureText()

, so keep that in mind.

Overall I'm not sure if this is a great solution, but this is the best I've come up with so far.

check the source code of the Googles Mozc project. The EmojiRenderableChecker class works really well! https://github.com/google/mozc/blob/master/src/android/src/com/google/android/inputmethod/japanese/emoji/EmojiRenderableChecker.java



it is similar to the compatible version for Paint.hasGlypgh (added in Marshmallow). https://developer.android.com/reference/android/graphics/Paint.html#hasGlyph(java.lang.String)
