Android. Pass data from activity to firefox addon

Add-ons Development
#1

Is it able to run firefox with parameters to my addon, which will execute suitable code? Or create callback for intent.startActivity from here https://github.com/cscott/skeleton-addon-fxandroid/blob/jni/bootstrap.js

This is a good question. Won’t Intents work? You can use JNI from addons -

Also here is some examples of jni using intents -

Here is an example of Firefox using intents to launch a config page

// Opening a preference screen from JS.
let jenv;
try {
  jenv = JNI.GetForThread();

  let GeckoAppShell = JNI.LoadClass(jenv, "org.mozilla.gecko.GeckoAppShell", {
    static_methods: [
      { name: "getContext", sig: "()Landroid/content/Context;" },
    ],
  });
  let Intent = JNI.LoadClass(jenv, "android.content.Intent", {
    constructors: [
      { name: "<init>", sig: "(Landroid/content/Context;Ljava/lang/Class;)V" },
    ],
  });
  let GeckoPreferences = JNI.LoadClass(jenv, "org.mozilla.gecko.preferences.GeckoPreferences", {
    static_methods: [
      { name: "setResourceToOpen", sig: "(Landroid/content/Intent;Ljava/lang/String;)V" },
    ],
  });
  let Context = JNI.LoadClass(jenv, "android.content.Context", {
    methods: [
      { name: "startActivity", sig: "(Landroid/content/Intent;)V" },
    ],
  });

  let context = GeckoAppShell.getContext();
  let intent = Intent["new"](context, GeckoPreferences);

  // preferences_privacy is the resource name for the privacy screen.
  // All the preferences resources are defined here:
  // http://mxr.mozilla.org/mozilla-central/source/mobile/android/base/resources/xml/
  GeckoPreferences.setResourceToOpen(intent, "preferences_privacy");
  context.startActivity(intent);

} finally {
  if (jenv) {
    JNI.UnloadClasses(jenv);
  }
}

So basically you can set up to listen to intents.

Yes, I was able to open my activity, now from my activity I want to pass data back in my addon , how can I do that?

#4

Setup your code to listen to intents. Then you can send it anything you want.

Yes, I used that code and opened my actvity successfuly, but now I want something like onActivityResult method in my addon. After closing my activity I want to get Data from it.
