After installing this, clean your projects and rebuild.

4.Android and calculating the size of a one-line string in a given font and font size?

Paint p = new Paint();

p.setTypeFace(TypeFace obj); // if custom font use `TypeFace.createFromFile`
p.setTextSize(float size);
float textWidth = p.measureText("Your string"); // you get the width here and textsize is the height.

mPaint = new Paint();
mPaint.setAntiAlias(true);
mPaint.setStrokeWidth(5);
mPaint.setStrokeCap(Paint.Cap.ROUND);
mPaint.setTextSize(64);
mPaint.setTypeface(Typeface.create(Typeface.SERIF, Typeface.ITALIC));
// ...
float w = mPaint.measureText(text, 0, text.length());
