Checking input in VideoCapture in Android Studio-CodePudding

I have imported OpenCV into Android Studio and created an EditText option for the user to input their camera's streaming URL.

I want to use VideoCapture in OpenCV to get the video feed from the camera but first I want to check whether the inputted streaming URL is valid and give an appropriate output. Something along the lines of:

if (VideoCapture(input) == true)
{
    // toast camera detected
}
else
{
    // toast camera not detected
}

I am unsure of the exact syntax to do this and would highly appreciate some help.

CodePudding user response：

Use URLUtil to validate the URL as below.

 URLUtil.isValidUrl(url)

It will return True if URL is valid and false if URL is invalid.

if (URLUtil.isValidUrl(url))
{
    // toast camera detected
}
else
{
    // toast camera not detected
}
