try {
JSONObject obj = new JSONObject();
obj.put("type", LOCATION_CHANGED_EVENT);
obj.put("location", url);
sendUpdate(obj, true);
} catch (JSONException e) {
Log.d("ChildBrowser", "This should never happen");
}
}
}
}
These are the errors I am getting in my ChildBrowser.java page:
Description Resource Path Location Type
ctx cannot be resolved ChildBrowser.java /childBrowser/src/com/phonegap/plugins/childBrowser line 228 Java Problem

You are looking at a wrong place.... To get the updated and working copy of childbrowser check here https://github.com/phonegap/phonegap-plugins/tree/65be38cf02466748a3b3e93c2d18cb2c198feb28/Android/ChildBrowser
UPDATE:-
Refer this http://simonmacdonald.blogspot.fi/2012/07/phonegap-android-plugins-sometimes-we.html
You need to modify few things like this
ctx.getContext() replaced with cordova.getContext()
ctx.startActivity() replaced with cordova.getActivity().startActivity()
ctx.getSystemService() replaced with cordova.getActivity().getSystemService()
ctx.getAssets() replaced with cordova.getActivity().getAssets()
ctx.runOnUiThread() replaced with cordova.getActivity().runOnUiThread()
ctx.getApplicationContext() replaced with cordova.getActivity().getApplicationContext()
ctx.getPackageManager() replaced with cordova.getActivity().getPackageManager()
ctx.getSharedPreferences() replaced with cordova.getActivity().getSharedPreferences()
ctx.unregisterActivity() replaced with cordova.getActivity().unregisterActivity()
ctx.getResources() replaced with cordova.getActivity().getResources()
import com.phonegap.api.* replaced with import org.apache.cordova.api.*
