Hooking a android.webkit.WebSettings method does not work...

[pnill]

Not sure what's going wrong here, I've added the following to hooks.json:

    {
        "class_name": "android.webkit.WebSettings",
        "method": "setJavaScriptEnabled",
        "thisObject": false,
        "type": "content"
    },

And have an apk with the following code: setContentView(R.layout.activity_main);

    WebView m =  findViewById(R.id.webview1);

    WebSettings n = m.getSettings();
    n.setJavaScriptEnabled(true);
    m.setWebContentsDebuggingEnabled(true);

I never see the setJavaScriptEnabled show up in droidMon as being hooked and I also never get an error produced.

String logVerbose = "JavaScriptDebugging: " + n.getJavaScriptEnabled(); Log.v( "Security App Test",logVerbose);

Doing the following I can see that javascript has in-deed been enabled though.

Wondering if you can help correct this.

Was able to correct this by tracing what getSettings was returning from the webview it turns out it doesn't reference a WebSettings object but rather something deeper which extends it.

https://android.googlesource.com/platform/frameworks/webview/+/android-4.4_r1.1/chromium/java/com/android/webview/chromium/ContentSettingsAdapter.java

So by hooking com.android.webview.chromium.ContentSettingsAdapter's setJavaScript method I was able to get the desired result.
