react-native-signature-canvas can not upload signature in android

[grinisoufyane]

it works fine in ios, but on android, I can't draw the image, and when I try to send an image it doesn't work. "expo": "~46.0.9", "react-native": "0.69.5", "react-native-webview": "11.23.0", "react-native-signature-canvas": "^4.4.1",

what are the errors you received?

even though sometimes the real error is not the reflected ones in the log, they do help you pinpointing the real issue

I am having a similar issue. Works fine on IOS but it seems the onOK prop isnt being triggered on Android.

<Signature
                // backgroundColor={drawpadBackgroundColor}
                backgroundColor={drawpadBackgroundColor}
                penColor={def.atrPenColor}
                onOK={() => {
                    console.log("TAPPED");
                }}
                // onOK={saveSignature}
                onEmpty={() => console.log("empty")} // Will add engine handler here for when empty sig is saved
                descriptionText={def.labelLanguageHint}
