#### Just wanted to give a try for android app development. 



I just accepted the 30 days challenge by **Miss Saumya Singh**. Her 30+ android dev videos are available on [YouTube](https://youtube.com/playlist?list=PLTV_nsuD2lf4UCTV6xwvNPvFdmCNKyhc8&si=TeQeeUKgmylKG1Mx) for free. I will be updating here my day wise things learnings and practice materials. All my source codes will also be placed in this repo. I am super excited to start my android dev journey.

Day 01 (18th October 2023)



1. Downloaded and installed Android Studio from [here](https://developer.android.com/studio). I can see my installed app details as below :



~~~

Android Studio Giraffe | 2022.3.1 Patch 2

Build #AI-223.8836.35.2231.10811636, built on September 15, 2023

Runtime version: 17.0.6+0-b2043.56-10027231 amd64

VM: OpenJDK 64-Bit Server VM by JetBrains s.r.o.

Windows 10 10.0

GC: G1 Young Generation, G1 Old Generation

Memory: 1280M

Cores: 12

Registry:

    external.system.auto.import.disabled=true

    ide.text.editor.with.preview.show.floating.toolbar=false

~~~



2. Created `First Demo App` from a template kind of thing with name `Empty Activity`. It took 6-7 minutes for me for completed gradle build/sync.



3. Configured `Google Pixel 7` as my emulator. I downloaded `API 34` as my system image for the emulator. It was around 1.4 GB. And I noticed `Pixel 3a` was already available for me to use as emulator.

Day 02 (19th October 2023)



1. In [this 2nd video](https://youtu.be/oUYgLzmUl0o?si=3twinfVD6-GQYVB_) I got a nice overview / structural and components understanding of the Android Studio. I checked them out myself in my system. Tried navigating all the buttons / getting ready to make hand dirty!!!

2. In [this 3rd video](https://youtu.be/ppPX65NU7ko?si=-O4M1lgS0P24AOhK) I understood / learnt some Kotlin or I can say Android Dev things, created my first Android App (tried myself in my phone + shared with my friends as well). From [here](https://github.com/Krushna-Prasad-Sahoo/test-android/blob/main/high-low-app_19thOct2023.apk) the same app can be downloaded & tried. The name I have given as `high-low-app_19thOct2023.apk`. And don't worry, it don't have any virus hahah xD

Day 03 (20th October 2023)



1. In this [4th video](https://youtu.be/qllC71SYHz4?si=5xp9e-AKqDdPHz6b) I learnt and tried to build a simple interactive app. Where there will be 2 buttons (black & tale). If you click black, the app backgroud / layout will be black and the same goes for other button. It was simple and niceeee :)



---

Day 04 (21st October 2023)



1. In this [5th video](https://youtu.be/QltvZXWsba4?si=TcRAy_XnMuNOnbtD) I understood the concept of multiple Layouts such as `Constraint Layout`, `Linear Layout` & `Relative Layout`. I saw some of their example use cases & I feel after implementing or playing around that will make me realise the concept thoroughly.



---

Day 05 (22nd October 2023)



1. Some motivation from [this video](https://youtu.be/hzAgqLkyRX4?si=c8Eezu8mQDuZpnHk).

2. I have tried Java earlier, but truly its tough for me. And I never tried anything with Kotlin ever. And [this video](https://youtu.be/fgfQeclyZiU?si=prXuP2FGnUZYXQL8) inspires me to continue this android dev course (makes me feel better that I accepted this challenge) -- even if I am noob with these languages. #continuouslearning

Day 06 (24th October 2023)



1. In this [6th video](https://youtu.be/1sjA4e_wG3w?si=UCP77uTSp2o60Mg7) I came to know about the Android Activity Lifecycle. There are a core set of six callbacks: `onCreate()`, `onStart()`, `onResume()`, `onPause()`, `onStop()`, and `onDestroy()`. There we discussed one more called `onRestart()` as well. I quickly went through the [Android Developer Official Guide](https://developer.android.com/guide/components/activities/activity-lifecycle#kotlin) for more understanding on this concept. So well explained!

Day 07 (25th October 2023)



1. From this [7th video](https://youtu.be/RHFrA6QPWPQ?si=0Ke1yXwc7eSrrjf6) I understood the concept of `Text View` and `Scroll View`. Its so nice, I tried to implement in my Android Studio, got some error like `API 33` is not working, need `API 34`. Tried to rectify it, but I don't where I clicked mistakenly the view of my studio got changed. I am not feeling well today about that. But my app was ready. I had 2 images, some long paragraph under image1, so that text scrolling can be tested. Will try again after taking a nap. Will let you know how it goes!



2. On my next attempt after few hours break I could build the app and run on emulator (also tried in my phone). Unfortunately, the 2 images didn't show up this time, but text view was scrolling as expected. I will try again building the images only with some dummy text. Before that let me tell you where I rectified to resolve the issue.

  - Go to `AppName > app` -> click on that , you will see a file called `build.gradle.kts` -> open it

  - There I changed 2 values to 34 :

     - compileSdk = 34

     - targetSdk = 34

  - Then click `Sync now` -> wait for a minute & then build. It will be done successfully.



3. I tried only puting a single image in `LinerLayout` and it worked. Now I will try with some text -> then will try the same app I was trying before "some scrolling text sandwiched between two images".

4. In my next attempt it wokred 100% as expected. Some scrolling texts are sandwiched between 2 images. Though this app is not much interactive, only can be seen n text can be scrolled, I learnt something new and interesting.

5. One thing I noticed that I would like to highlight that in any dummy text if a `&` symbol stay, the studio throws an error. I don't know why, but by seeing the logs & error messages I could understand them. I changed all `&` into `and` -> then it worked perfectly.

6. From [here](https://github.com/Krushna-Prasad-Sahoo/test-android/blob/main/scroll-text-app_26thOct.apk) the final app `scroll-text-app_26thOct.apk` can be downloaded and tested.

Day 08 (26th October 2023)



1. Received some hints from [this video](https://youtu.be/1VuTaNbRkkQ?si=8wToZW_X4Hm9yWkG) on troubleshooting many issue while working in Android Studio. I'm already working on this ...



---

Day 09 (27th October 2023)



1. In this [8th video](https://youtu.be/47teINBTF08?si=zdxyRa6jX_5PW6p1) I understood a new concept. When we have use case such as when you click a button -> new app opens up or if you click a button & another page of the same app open up -> then in that case we have to use `Intents`. There are 2 types of Intents.

   - Explicit Intent : Explicit intents are used for communication inside the application. Like changing activities inside the application.

   - Implicit Intent : They are used for communication across two different applications.

2. I just loved it... I am truly amazed with the APP I created now after one hour work. Its size is 25 MB, so I am not able to upload it here in GitHub but yeah I will explain you how it works. So I have used the concept called `Explicit Intent`. So when you open my app -> it will show you a place picture & its name, below the picture you will see 3 buttons as `Visit XyZ` -> So when you click it you will be seeing another page with that place & 3 button below (to come back to the 1st place or to visit some different place) . I was so amazed because it worked in my first attempt without any errors.

3. I have a plan to create a homepage & keep thier 5 buttons to visit 5 different places. Every place will be available on different page with a image, some text on the place and a back button to come back to home page. Then I will share it with my family and friends. I will start from a scratch new project for this. I am so excited!

Day 10 (28th October 2023)



1. In [this video](https://youtu.be/gG7sqvJjLaE?si=95Qab813AqIDrOix) I got the commands to push the android projects to github repository. I was aware of this thing earlier and the commands as well. So it was a nice revision for me. I am working on the project that I mentioned yesterday, I will upload that in the same way - in a new repo.

2. First you need to download git/gitbash in your local setup. Then you can use git commands to push the project files after authenticating.

3. Sharing the commands below :



~~~    

- Check status : `git status`

- Initialise  : `git init`

- Add remote location with name `origin` : `git remote add origin https://github.com//`

- Check remote location : `git remote`

- More details on remote location : `git remote -v`

- Put all files into staging area : `git add .`

- Check status : `git status`

- Save all changes : `git commit -m "Adding all project files"`

- Check status : `git status`

- Check branch : `git branch`

- Push to remote repo in `master` branch : `git push origin master`

~~~

Day 11 (29th October 2023)



1. It was a busy day for me. I haven't done any thing with respect to Android Dev today. Will first complete the yesterday's project. Then will continue learning new things.

2. The project is ready now! i.e PlaceSage is your gateway to India's finest destinations. Explore, discover, and uncover the treasures of Delhi, Mumbai, Kolkata, Bangalore, and Bhopal – all in one app.

Day 12 (1st November 2023)



1. From this [video](https://youtu.be/YVfBEowGBU8?si=T-rNdr2psH9reub8) I did learn about `Implicit Intent Concept` in Android. Implemented it as well. My app was working well on my phone, but the emulator on Android Studio was failing when the `camera` was opening or `chrome` browser was opening. It was not throwing any error, but I felt like it was getting restarted.

2. Also, I understrood another view called `CardView` and implemented that in this test.



---

Day 13 (3rd November 2023)



1. In this [video](https://youtu.be/VmPo5OV70yM?si=Ka38heiBVQEHxN_B) I got a new concept of `WebView`. It was really interesting. With this power I was able to make multiple website's clone mobile app in few minutes. And also I have few friend who have their personal website or portfolio. I gifted them with a mobile app of their portfolio or website. Hahaha xD. This was awesome.

2. Also in this video I came to know how to take user permission for _Internet_ and also I learnt how to create a function in Kotlin using `fun` keyword.



---

Day 14 (4th November 2023)



1. In this [video](https://youtu.be/a5tc0QALO-w?si=RryqSbnDHBWFzxCh) I received an idea (or better to say an assignment) to try and implement it. It uses all the concepts learned till now, incluing buttons, multiple views, explicit & implicit intents and to make the app little interactive. Need to find few things by own. Let's see when I can try it.

2. I am planning to add Implicit Intent concept in my previous project i.e `Place Sage` -> a simple button to call or send a mail kind of thing.

3. I did that yesterday (13th Nov) - button added, logic added, but sadly it not working. App is crashing upon pressing the call button. I am sad.



---

Day 15 (5th November 2023)



1. In this [13th video](https://youtu.be/kGb2aQV2H1c?si=FunHLTlL5tCl-0cI) I understood few concepts on how to capture user data, and pass them to another screen.

2. Implemented a small demo app - `Nothing Cafe` where user can pass some name of the food then press the _Order Now_ button, in the next page it will just show that orders placed.

3. During this mini app, I learnt about `companion object` concept, `toString()`, passing data via `key` and value in `intent.putExtra()` .



---

Day 16 (6th November 2023)



1. [This video](https://youtu.be/kGYOGJeBPhY?si=GEqsxJ9QZ8Q34IUw) was really great. A long one but worthy, learned a lot about `LogCat` - how to check the logs and troubleshoot, filtering out logs, adding tags in application code etc.

2. Secondly leanred and implemented another concept called `Splash Screen` using `Handler().postDelayed()` method.

3. Also, got a trick i.e to hide the action bar we can use `supportActionBar?.hide()` method.

4. Here the interesting thing(`?`) is used to handle the Null value (in case it is present).

Day 17 (7th November 2023)



1. In [this video](https://youtu.be/7TyaGn0I2d0?si=FJ-JthYoJcRw5DWQ) I understood about `gradient` colour creation in Android Studio as per own requirement and how to use that as app background.

2. I learned and created a `vector assest` of a person, mail, password in `drawable` folder, implemented that on login page.

3. Nice colourfil login page created, will proceed further with next class.
