Some mobile devices are experiencing issues with Android webview not executing javascript functions

Everything was running smoothly on my webview app on the HUAWEI RNE-L22 and iPhone. However, when I tried to run the app on the samsung SM-G530H, it failed to execute my JavaScript function. Surprisingly, the function worked fine on a normal phone browser.

The code snippet below will not work:

function alertFunction(message){
 alert(message);
}
$(document).ready(function(){
    alertFunction("Welcome");
});

Only this version works:

$(document).ready(function(){
    alert("Welcome");
});

I am unsure if this issue stems from my Android webview or the website that I am loading into it.

Answer №1

It is recommended to implement a JavascriptInterface:

mWebView.addJavascriptInterface(mWebBridge, "Android");

within the Bridge class:

@JavascriptInterface
public void ShowAlert(String message) {
    //Implement custom Android dialog here
}
