Android Emulator Worked after a lot of hard work

It was most awaited thing to see the app running on the emulator of Eclipse (worked from 6pm and I could resolve the errors and see the app running at 2:53 am ).

I used Android Studio initially for the developing. It is very easy to work with as it involves dragging of the widgets when it comes to front-end development.

Later I switched to Eclipse.In Android Studio when you click on RUN button it runs the emulator without running the app even though your code may contain errors. But in Eclipse it is opposite it runs the app on the emulator only when the errors are fixed.



                                                          

Most common complaint : "R cannot be resolved to a variable"


Here are couple of things to do to get rid of this annoying error:

i)   You must right click on your project name
ii)  Go to Properties
iii) Select Android , and check the Android v.x   (v & x are integers)
iv) Next select JavaBuild Path check the Android v.x   (v & x are integers)
v)  Close the Properties window and open the Project menu and click on Clean... and next
     Build.

                                               Man !! It is not yet resolved:


Careless thing is that we don't check the package name in the AndroidManifest.xml and the android:attribute values. Make the appropriate changes and you can run your app if "R cannot be resolved to a variable" is the only error

$1337 YouTube Community (Posts) bug

YouTube Community  is a feature that is only available for Channels with  1. Verified Phone numbers 2.  A significant history, more content for years. In the early June I started hunting for Security flaws on YouTube I was roaming around the features but most of the places have been found secure or already potential features had the bugs fixes in place. The Community Tab is now Posts So, I thought to exploit Youtube Community feature. I was trying to delete the Posts using IDOR attacks but it didn't work I was tired of trying various attacks but thought to compromise to the least "Privilege escalation".  The Security flaw... A user (victim) created a YT Community post, later an attacker while being an Admin of the same Channel has saved the HTTP Request that deletes a Community Post / Poll, then the attacker can replay that HTTP Request after he's demoted from Admin to Subtitle Editor  that would delete the Post / Poll. I exploited this flaw I tried after 15 ...

Google form setting Bypass - Making my way to the Google's Hall of Fame !

  G o o g l e ! Bug : Circumventing "Limit to 1 response" of  Google forms  ( Parameter Injection )        Discovered on: 30th, November 2016.            Research Time: 2:00 p.m to 9:30 p.m. Earn more by display ads on blog with  Lithific Ads The setting is "Limit to 1 response" which means only one response per user. Once you filled the form there will be no chance to edit the responses or again fill a new form. If you open the form to fill again, the response would be like the image below. There is no way to edit or fill another form (Hurdle 1). I created a test form and checked "Edit after submit". Once this test form is filled I can change the previous response.  I clicked on the "Edit your  response"and intercepted the request.  I changed the form id and forwarded the request. I was able to see the form that was submitted. When I edited the form and submitted, a blank form ...
