Google Associate Android Developer Practice Exam

1. Exam Overview

Hello. Let's pick the developer certification exam. I'll show you what to do with our sample exam before submitting it for grading. Let's start with a review of what we have at the beginning; we are going to have the result. First of all, we have some tasks to perform. Secondly, we have source code. Zap is already buildable for the project, and according to the tasks, we need to realise some features in our project. Also, we have an updated specification with descriptions of different screens, their sizes, and so on. The result should be the source project for review. We realise it comes from our tasks. So let's go to the next video.

2. Define a local database model and data access object (DAO) using the schema app/schemas/tea.json for the data structure

So let's start with our first task. At the beginning, we need to define a local database model and data access object dial using this chamber data structure. Let's go to our first German. We could see descriptions of databases. Here we have a stable name "T," several column names, and so on. Let's compare it with our data model. In data we could see for example table name,table description start with uppercase d in tier jasondescription starts with lowercase d and so on. As a way to compare is launch our project. I told them at the start that the project is buildable, so we could run it and get a generated JSON with a database description, which we could compare to the edgeson. So a comparison of data structures told us that there are mismatches with table names, novel values, these column names, and so on. So let's start with fixing it in the Tia Fix-N-Now constructor. We could see that it contains title access to a table, prompting us to rename it here too. So now it looks cool. After the second launch of our location, we could get the next generated version of this on file here and, after comparison, we could delete differences like version and primary cave type, which are not important for now. Let's go to the next video.

3. Use the getSortedTeas method from the DataRepository to create a sortable rawquery for the data in the list

Let's continue with our first task. In this step, we will use the sorted tiers helpful class and the guest tiers method from the data repository to create a sort of query for the tier, at least. Let's go to data repository get started here atfirst what we can see here Get all the mail from teardown that is used here. Take note of any sorting. So it's not cool. Let's use another method. We'll name it get all sortedas parameter clear from sorted fields. We need to add something like this. Now how do we use the guest method? Let's go to the ListView model. Let's add live data here we have data pageat least and we will fill it with repositoryget started and we are ready to return it. It doesn't matter where you are this week or not, it doesn't matter where you are in the date repository. But let's get back to the list model view. So we're ready to work on getting all tiers, and it'll be a short tier at the very least. So that's all ball this step. Go to the next video.

4. Populate initial content into the database from res/raw/sample_teas.json

As a result, the final step of our first task is to populate the database with initial content from restaurants. Let's go to a restaurant. We could see data for populating the database with correct column names and so on. Let's go now to our database. And we can see here that we are ready to populate it with loading JSON, but the method is still running. Data is never used. As a result, loading is a breeze. Also, we can see that it's instanced in your database, which you declared but never told to return always now.So let's start with what we could do. If the instance is now, we should generate it with the database builder, and an important thing to remember when creating data is a callback; once the database is created, we want to execute our newly generated task to operate sync and methods. In the background, the Kilobytes starting date is executive, so this should work. If we don't want to use the same task, we could enable it, but it's not good practice. So I think the task looks better for me. So that's all we need to get started.

5. Display a card showing the data most recently added to the list in the MainActivity. The card should update when a new data is added

The card should update when a new tier is added, so let's go to the main activity. First, several fields that are commented out. Next, the feeling of the card image is something strange, so let's comment this. We need to add a tierview model here and work with several observers and observers to fill the table something like this: filling name, description, a description, a description, a description, a description, a description, a description, a description, a what about set favourite itself Here's something to change so let's do this way we're going to change his favourite regular like in the checkbox in repository error looks mostly good but one more moment something could look like not good because incremented and ordered by favourite and ask is something not cool let's change this in this way now we're going to get the last added .

6. Create a list-item layout for the RecyclerView using ConstraintLayout

In our first step, we need to create a list item layout for the result review using constant layout. First of all, let's go to our specification to look for our list item style. So here is our list and our list items and descriptions of list items, elements, sizes, colors, and so on. Now let's go to the layout and create a new layout. At least one resource file should be named item. We could work with a decision tree or with a text editor. Let's demonstrate in the text editor that, first and foremost, the parent layout should be nonstate layout, and that within all of our text, you can see only to add magic. The next step is to add a text view with the account name style and it should be all specific is this moment when layout can stay top to bottom off and the last moment we are going to text with a steep timer, and now it appears that our item layout is ready, so let's move on to the next redo.

7. Bind LiveData to the RecyclerView list item using the paging library

In our first tab, we need to bind live data to the static review list item. Using the page library, you can see that the list item layout was edited in a previous step. So now we need to get a way to bind data to its fields. So first of all, let's go to the tier adapter. We need something like page at least of tiers andwe need to change catrey holder and holder methods. So let's say our boundary holder and our colorview holder are connected with this item. What about the boundary holder? Hold on. Let's change "bind" to "let's connect with our values" in this item layout. So this is a way to bind a list item. Now let's go to the list activity where the adapter should be used. So we want to add here an adapter to work with the history model. One important thing we want to take care of is this, and we want to connect it with preference data from settings ordered by sort of. So when we change our preferences, it's stored, and we want to have a way to get it. So I will add a simple package that is already added. It's preferences packages and preference helper class justgenerated and what we want to do here. Let's go to the text window now that our TDs view model is connected and selected in our setting preferences.

8. Create a notification in WorkManager that shows a notification to users once a day with a random data and on click opens TeaDetailActivity

In our view step, we need to create a notification in Work Manager that shows a notification to users once a day for a random team and then click Open State Activity. We need to use random whenconstructing Kavaq to return random data. First of all, I want to take careabout that notification depends on our wherever toshow notification No, it depends on whether switch preference/prefer notification K is on or not. Default value is false. I'd like to move default to resource fileto Boolean and in bulls XML created previouslycreated resource file default value false. I should have used it later when I tried to get the preference value "dynamic loan," so now let's go to our searching segment to show when this preference changes. One more thing that could be important indescription in our task, there are no explanationwhen exactly should notification be showed at first. So no moment when notification shouldbe showed at first time. So I'd like to do as I understand this: every time the preference case is on, I try to start my notification welcome, and it should be repeatable every 24 hours. So once a day from switches on when switches off,I'd like to cancel our workers with worker talk. So let's go to our notification worker itself. We can see the channel ID, so we need to use channel if it's possible; let's type "change Duval preferences for help." I already mentioned this class, which consists of just a few getters to help us get our preference value generated from preferenceXML, and I attempted to use channel for the next step, sending notification in notification Builder, where we want to describe the style and behaviour of our notification. First of all, let's look in our specification for details about our notification. Here, we can see how it should look and the icon title text feed. So let's continue our title message icon, and next, what we should be focused on is what happens when location is clicked on. Charge Activity should be open so that we can transfer data from our education intent pending content to our additional data, which is your name. Let's take care about the name here isreally random team get random from the repository. Take us to tear down this one cure just a setupfrom t word type something not strange, not useful here. So let's take care of this. So this way looks better. It's not only one possible way, but just one of them. So our notification worker should now do what it should. Let's go to the next video.

9. Address the following comment form our QA team: When I view TeaDetailActivity and click on the favorite icon in the menu nothing happens.

Step six attests the following comment from our QA team: "When I view their data activity and click on the favourite icon on the menu, nothing happens." So let's go to our tier data activity so not surewhat do they want really several problems here first of all. Nothing happens our icon four favourite and nothing happens withdata for our display team so first of all. Let's it's not but we have several same logic favourite duckso let's create the same one all the difference is withcar all data is the same so just copy past andfor car changed go back to our data activity not best We talked about it being a good show, so what happens? Display team is executed from observer, so it could be executed before on the options menu after it this moment, so if the menu is not already ready set, we should change the icon, or if we are not ready to work with manual, we should change it after new is created, so this idea could be another realization, but now, return should be true, and what to do when an option system is selected. if action favourite we should change state of favourite 40 inour database so we should do this awesome task because it'snot safe to work this way should work look like that'sall go to the next video.

10. Implement a custom SteepProgress view in TimerActivity and display a time of 4:00 minutes when launched from MainActivity

Step seven implements the custom step progress view in the timer activity and displays time on 40 zero when launched from the main activity first. So now let's go to our time and activity. We need to implement the progress and model view here, so let's do the time review model from our time. We need a check mark. Our timer is constant from the timer remodel; it's already set to 240,000 milliseconds, which equals four minutes. The next step is to set up the server for the timer view module to get the time for the timer to change. teep progress and let's go to our timer view modernone only moment here is that construct time we'll set the steep timer here Next video.

11. Write a UI test to validate that clicking on the Filter by Favorites icon in the toolbar updates the RecyclerView

Step eight, right? I tested to validate that clicking on the filter by favourite icon on the toolbar changed the result on view. First of all, let's talk about our source project. There are some problems when our action filter icon in the toolbar is clicked on. click would see that ouralts the page increased data for our soccer view isnot updated when favourite filter is updated. So it's not observers for the filter or dependencies. So we need to take care about it. What if updating filter executed repository updating, but that's not the way to go, so let's go with all three. We wanted to create our page list with tiers in the same way as previously. So it should not be final. Now sort by "Show favorites," and let's go back to the list of activities again. Show favourites with our Preferences helper class to "set veil" from our settings ordered by veil in preferences, and our OGS has changed its new object now. So we need to recreate observers for it. So our old tiers are observed again. So we are ready to walk with UI test itself now. To create a UI test, we need to click Control Plus Shift Plus T to add a new test. It's already here for me. So let's go to it. So that was just a moment. We need to take care about dependencies. Because not all required dependencies could be added in build gradle. So with Imports we will need something like this. With the activity test tool, we should work with our tierlist activities, where our view is stated, and our toolbar. So let's go. What about testing itself? So to compare, the recalculation is updated. There are numerous instances of me and coffee. We compare result view objects with result view adapter objects. I'm going to compare the result view and the adapter item count. There could be only one problem if all items were favorites. So clicking on the filter by fair rate icon should do nothing. Should not call change in our visible recycle you. But it's a description of the test. So let's continue with your test. First of all, adapter size before and after Let's try to get them. We will get the same result of view from our activity team as in the list activity and get item counts in its adapter. Next, we need to implement a click-to-filter by favourite icon. It's action filtering into a bar. So let's try to click it. And finally, we need to compare if the adapter size before is equal to the adapter size after. And if it's too testy, it should pass something like that. To run the test, we need to, for example, select here or click the Write button. So that's all for our last step, center.
