Android - Passing JSON object from webview javascript to java - Stack Overflow

programmeradmin7浏览0评论

I have an Activity with a webview and a javascript interface on the java side.I would like to write a method in Java that can accept a json paramater from the webview.

@JavascriptInterface
public String test(Object data) {
    Log.d("TEST", "data = " + data);
}

on my webview javascript I call:

MyAPI.test({ a: 1, b: 2 });

but the data variable is null.

How can I pass JSON objects from webview javascript into native method?

Thanks

  • 3 You can only pass Strings and primitives. – njzk2 Commented Feb 25, 2014 at 22:01

Reset to default 3

You can use GSON library or similar to create Stringified JSON to Java object, and JSON.stringify(data) on JS side

@njzk2 is right, do it like this:

In JAVA:

@JavascriptInterface
public String test(String data) {
   Log.d("TEST", "data = " + data);
   return "this is just a test";
}

In JS:

// some code 
var result = test("{ a: 1, b: 2 }");
alert(result);
//some code

function test(args) {
   if (typeof Android != "undefined"){ // check the bridge 
      if (Android.test!= "undefined") { // check the method
         Android.test(args);
      }
   }
}
