Issue with phonegap plugin for adjusting screen orientation

I encountered the following issue:

Uncaught TypeError: Object # has no method 'exec' at file:///android_asset/www/JS/pg-plugin-screen-orientation.js:4

var screenOrientation = function() {}
    
    screenOrientation.prototype.set  = function(str, success, fail) {
    
     PhoneGap.exec(success, fail, "ScreenOrientation", "set", [str]); // ERROR OCCURS HERE
     
    };
    
    navigator.screenOrientation = new screenOrientation();

I have carefully followed the instructions provided in this document: https://github.com/champierre/pg-plugin-screen-orientation

After making necessary changes, the functionality is working correctly. However, the application crashes when executing this line of code:

activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

Answer №1

Could you please specify the version of PhoneGap/Cordova you are currently utilizing? It's worth noting that in more recent iterations, the PhoneGap object has been rebranded as cordova. Therefore, it may be necessary to revise the JS file to reference cordova.exec as opposed to PhoneGap.exec.

Answer №2

Whenever I try to execute the exec function before the onDeviceReady() event is triggered, I encounter this error.

The onDeviceReady() event must be fired first.

This error occurs when the event has not yet been triggered.
