So far, it looks

MaciejGórski if you don't mind (if you do, I will remove this post) I compiled your code into ready to use method:

private LatLngBounds boundsOfTile(int x, int y, int zoom) {
    int noTiles = (1 << zoom);
    double longitudeSpan = 360.0 / noTiles;
    double longitudeMin = -180.0 + x * longitudeSpan;

    double mercatorMax = 180 - (((double) y) / noTiles) * 360;
    double mercatorMin = 180 - (((double) y + 1) / noTiles) * 360;
    double latitudeMax = toLatitude(mercatorMax);
    double latitudeMin = toLatitude(mercatorMin);

    LatLngBounds bounds = new LatLngBounds(new LatLng(latitudeMin, longitudeMin), new LatLng(latitudeMax, longitudeMin + longitudeSpan));
    return bounds;
}
