Multiple Runtime Permissions in Android Without Any Third-Party Libraries

Nov 11, 2018

In my current project at work, I had a task to add run time permissions in an android app whose code is very old and using legacy methods and frameworks/tools. Normally, I use Ted Permissions in all my apps for the runtime permissions and I must say that it’s one hell of an amazing library I ever saw and given the complex scenario and flow of runtime permissions in Android (thanks to Google who always makes sure to make every thing more complicated than ever), this library makes the runtime permissions like a breeze.

Today, when I was working on a project, so I had a situation where I had to perform a very tiny operation in background in Android.

Converting JSONObject to HashMap<>

Nov 11, 2018

Today, I had a huge Json in my app and I wanted to fetch all these values in a general way. I also wanted to parse Json for only one time to avoid try/catch each time I access any value. So, first thing I had in mind was to convert the JSONObject in the HashMap or Map<> etc. So if you are using Gson in your apps for json mapping, then you can use this one line code for conversion.

Overestimating the “Underestimating”

I don’t know much about this but I will try my best! Photo of Deosai Plains (Pakistan) February 2018. I left my previous job and started looking for a new job. I had some interviews lined up.

Podcast — What’s Open Source? And What’s Hacktoberfest?

Oct 10, 2018

I have always been more focused on writing and reading medium than the listening and speaking. But, recently I have started giving talks and doing public speaking a little. And I must say that I have been enjoying it a lot. And then an opportunity knocked my door and presented an other option for me to explore. That was podcasting and sharing my knowledge through audio channels. I have never created or talked in any podcast, so I was curious and interested at same time to explore this and see how this plays for me.

I Didn’t Accept Job Offer at Facebook. Here’s Why.

I woke up at around 5:30 AM in morning. I was feeling very sleepy as I slept late at night. But it was no time for laziness as I had to get ready for traveling. I made tea and ate some bread as quick breakfast, got shower, locked my home and called Uber. Uber took me to a bus stop where I booked a seat in a bus. The bus was late about 20 minutes, but I left Karachi — the city of lights — at 7:20 AM.

The Road to 1000 Followers on Medium Since the childhood, I have remained a silent but talkative person. Now you must be thinking about how someone can be silent as well as talkative both at same time. There’s no middle ground in those two attributes. Well, my answer to that is at start I am a shy and silent person to any new person. But when I become comfortable to him/her, then I think (s)he can’t stop my on talking.
