Monetise your Android app | Admob integration | with code...

-
Making an Android app is one thing but earning from it is other. There are many ways to earn from apps like premium packs, subscription, buying stuff, ads. 
The advertisement would be the most efficient one and will give you good revenue. There are many advertising networks but Google provides AdMob which is more preferable in terms of standard and revenue too.

So let us start to code. I'll explain two types of ads only if you want me to explain the other two, comment for the same.

Steps to integrate AdMob into your Android app:

 1. Creating an Admob account

  • Go to AdMob site sign in with your Google account.
  • Create an app and note down the App Id, which we'll use in our app to authenticate.


2. Import Mobile Ads' SDK

  • Open your gradle files and in your project-level gradle, put the below code, inside allprojects {} section.



3. Add Dependencies

  • Add the following in your app-level gradle.
  • The version may change you might want to check: Google Play Services





4. Update Manifest file

  • Add the following code to your manifest.xml, it includes metadata that'll authenticate your app with the AdMob app.


5. Initialize Mobile Ads

  • Add the Java code in your Acitivity.java file to initialize the Ad SDK.
  • Google encourages developers to use the sample app id for testing purposes, hence use the sample id.


6. Choose Ad Format

  • There are 4 ad formats provided by Google. For an app that includes a single page of multiple user interactions than I'll suggest going for Banner ad which appears at the bottom and will not distract the user.


Implementing Banner ad:

 Before moving forward, go to the AdMob account, click AdUnit add one Banner ad, note down the Ad Id.


 a. Add AdView to the layout file

  • This will add the ad to the activity layout, you don't need to make changes here since Google will manage the resource formatting. Also, sizes can differ, follow the page for sizes: Banner Sizes


 b. Or create AdView using Java code

  • Simple process, but recommend using the XML style.


 c. Load an Ad

  • Use the following code to initialize the AdView and assign money-making ads.


 d. Ad Events (Optional)

  • Use some events for customizing ads on your device.




Implement an Interstitial ad:

  Before moving forward, go to the AdMob account, click AdUnit add one Interstitial ad, note down the Ad Id.

 a. Create an object of the Interstitial ad:

 b. Load an Ad:


 c. Show the Ad:

 d.  Ad Events for reloading


Source Code:

  • Sample Interstitial app on GitHub
  • Sample Banner app on GitHub

Audio de-noising using Python (Wavelets)

-
What is audio de-noising? Audio de-nosing is a process of removing noise(unwanted sound/signals from audio). You might have heard of noise cancellation headphones, these remove all the noise from the audio.  This process has various applications in media creation and learning. Also, de-noising is not only done on audio but also done on images. There are various methods to do this. We will see 2 methods and implement one. Method 1: FFT (Fourier Transform)    There are multiple different implementations of FT: FFT (fast FT), STFT (Short time FT). Also, there are inverse for each of them IFT respectively. So what is it? In short, FFT converts signals from one form to another, in audio, the time-series signal is converted to the frequency domain. More shortly, the dominant audio (your voice) will have more power than the non-dominant(noise). The following video will explain (a really good video):  Denoising with FFT (in Python)  Method 2: Wavelets (faster than FT)    These are complicated

Using FFMPEG to trim your videos

-
 There are multiple methods to trim or clip videos with the help of FFMPEG, but sometimes looking at the documentation can confuse lots of us, and we cannot derive the output we want. And the examples on the documentation are simpler than what we want to do. So I will show few methods to combine, trim or clip video files using FFMPEG. I won't be going through installation process and will assume that you already have it installed. 1. Using timestamps to clip the video 🕐   ffmpeg -i video.mp4 -ss 00:00:00 -to 00:10:00 -c copy output.mp4   This command will copy the clip from 0 sec to 10 min without re-encoding, since we specify not to re-encode. Break down of command:      -i  : input video file     -ss : starting timestamp you can define in hh:mm:ss or just secs     -to : ending timestamp, this is the timestamp of the video     -c copy : codec is copy, which doesn't require re-encoding   If you want to copy the video from some other time to some duration    ffmpeg -ss 00
