To send some instructions to a server process I needed to send UDP packets from an Android device. Normally I would \u201cgo native\u201d and java\/kotlin but for this one I tried phonegap. This is a reminder of a couple of tweaks needed.<\/p>\n\n\n\n

You need this package:-<\/p>\n\n\n\n

cordova-plugin-chrome-apps-sockets-udp <\/p>\n\n\n\n

ie cordova plugin add cordova-plugin-chrome-apps-sockets-udp <\/p>\n\n\n\n

I also wanted to check a web page so used the cordova “in app browser<\/a>“<\/p>\n\n\n\n

That worked on older Android but on on newer versions gave the error net::ERR_CLEARTEXT_NOT_PERMITTED .<\/p>\n\n\n\n

To fix that needs tweaks in the project config.xml needed the xml android namespace adding as below<\/p>\n\n\n\n

<widget id=\"com.whatever.app\" version=\"1.0.0\" \nxmlns=\u201dhttp:\/\/www.w3.org\/ns\/widgets\u201d \nxmlns:android=\u201dhttp:\/\/schemas.android.com\/apk\/res\/android\"\nxmlns:gap=\"http:\/\/phonegap.com\/ns\/1.0\"><\/code><\/pre>\n\n\n\n
and in the platform stanza<\/p>\n\n\n\n
<platform name=\"android\">\n<edit-config file=\"app\/src\/main\/AndroidManifest.xml\" mode=\"merge\"   target=\"\/manifest\/application\">\n  <application android:usesCleartextTraffic=\"true\" \/>\n<\/edit-config>\n........rest of the platform entry\n<\/platform><\/code><\/pre>\n\n\n\n
