Basically, it works like a stack where each view is stacked on top of the other.

Create a drawable file for shadow view and assign the name image_shadow and add the below code in this file.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <corners android:radius="10dp" />
    <gradient
    android:angle="270"
    android:centerX="300%"
    android:endColor="#99000000"
    android:startColor="#00000000"
    android:type="linear" />
    <size
    android:width="270dp"
    android:height="60dp" />
    <stroke
    android:width="1dp"
    android:color="#878787" />
</shape>

Now, open xml file and add the below code into it, and set this drawable file as view background.

<androidx.appcompat.widget.LinearLayoutCompat
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context=".MainActivity">
<androidx.constraintlayout.widget.ConstraintLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <androidx.appcompat.widget.AppCompatImageView
        android:id="@+id/imageView"
        android:layout_width="250dp"
        android:layout_height="250dp"
        android:scaleType="centerCrop"
        android:src="@drawable/shopping_image"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"/>
    <View android:id="@+id/view"
        android:layout_width="250dp"
        android:layout_height="250dp"
        android:background="@drawable/image_shadow"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"/>
    <androidx.appcompat.widget.AppCompatTextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="10dp"
        android:textColor="@android:color/white"
        android:text="Write your text here"
        android:textSize="25sp"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintBottom_toBottomOf="@+id/view"/>
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.appcompat.widget.LinearLayoutCompat>

That's it. You should be ready to go.

Here we will learn, how to import annotations saved in the database using PDFTron.

In my last blog, we have learned how to save annotation in the database.

Events for import annotation

At the time of document load, we will get all annotations saved in the database using AJAX call and then we'll import that annotation. Now the question is if we import annotation than that will be drawn and again annotation changed event will fire and again annotation will be saved (as I say in my last blog), so this will become an infinite flow, but we can overcome this problem by checking if an annotation is imported or not. If an annotation is not imported then only we'll do save annotation in the database process otherwise we'll ignore it.\

When we draw any annotation "annotationChanged" event will be fired, and check if it is an imported annotation, then we can ignore it(eg, save annotation process).

Here is an example of how to import annotation from the database.

Example

WebViewer({
    path: 'path_to_the_PDFTron_'lib'_folder_on_your_server',
    css: 'webviewer_css',
    licenseKey: 'YOUR_PDF_TRON_LICENSE_KEY',
    initialDoc: 'YOUR_FILE URL' //url of a file to load
}, document.getElementById('viewer'))
    .then(function (instance) {
        let docViewer = instance.docViewer;
        let annotManager = instance.annotManager;
       
        annotManager.on('annotationChanged', (annots, action, e) => {
            //if annotation is imported we'll return
            if (e.imported) return;
            //when document will loaded we'll get annotations fro db
            docViewer.on('documentLoaded', function () {
                $.ajax({
                    url: `URL_TO_SAVE_ANNOTATION`,
                    type: 'GET',
                    success: function (result) {
                        if (result.success) {
                            result.data.forEach(annotationObj => {
                                annotManager.importAnnotations(annotationObj.annotation);
                            });
                        }
                    },
                    error: function (result) {
                        console.log(result);
                    }
                });
            });
        });
    });

Simply put, the rule of 10 X is taking any target you set for your company or sales team, and multiplying it by 10.

So if the goal is to increase revenue by 5% using the 10X rule, you will increase that goal to 50%.

What the 10X rule does is force you and your sales team to think in terms of LEVERAGE. Because all of a sudden, instead of focusing on the “real” goal, the goal is achieved through the roof.

Contact customer acquisition with a solid plan. Build a foundation by developing relationships with your target audience.

Achieve customers differently as you progress toward strategic goals. Here are four lessons to guide your team:

1. Create an engagement

It is highly unlikely that a first time visitor will stumble upon your website and automatically purchase your products. Potential customers should be fully engaged with your brand before making a purchase.

2. Be present on social media

If you are not present on social media, you are lost in a huge market that your competitors are already taking advantage of.

Having a social media presence should also not be expensive. Creating a business account on Facebook, Twitter, Instagram, and LinkedIn is free. Just join discussions and groups related to your industry. Provide helpful answers to questions and insights on various posts to make yourself known.

3. Keep your sales simple

Everyone is on sale, even if your job or business has no impact, Cardo told those in attendance. And many entrepreneurs and professionals overreact to it.

Sales is a game of touch. It’s about finding someone who can buy, who has the power to make decisions, and who is interested. Then you contact them with offer fur, talk price, and ask. It's not always easy, though it's really easy. The most successful salespeople focus on simplifying their sales process.

4. Put your problem customers

We have it all - the customers that we meet today or in the future take up more of our time for business.

5. All your customers are committed to staying in touch after purchasing from you

Keep an eye out for ways you can sell them extra items. Don’t keep your customers engaged to monopolize your time, but you can help them gain an understanding of strategy opportunities.

6. Host an event

Hosting an event is a great way to do this because it gives potential customers the opportunity to meet your brand on a more personal level. Depending on your product or service, you can either host a personal event where customers can meet you or host an online webinar where it still feels personal - just like you are in front of your audience.

Development:

What is a Balanced Scorecard (BSC)?

• A Balanced Scorecard is a performance metric used to identify, improve, and control a business's various internal processes and resulting outcomes.
• Balance Scorecard is a framework to implement and manage strategies.
• The Balance scorecard is derived from the idea of looking at strategic measures to get a more balanced view of performance. The concept of a Balanced Scorecard evolved beyond the simple use of perspectives, every business can implement it according to the requirements and therefore it is a holistic system for managing strategy.

Why do we need to implement it?

• The key benefit of using a BSC framework is that it gives way to the organization  to "Connect the Dots" between various components of strategic planning and management and it means there will be a visible connection between Projects and Programs that people are working on it.
• BSC framework also helps management to meet pre-decided targets.

Perspectives of Balanced Scorecard:

The framework Balanced Scorecard divided into four areas (perspectives) that are critical to business success as given below.

1. Financial 
2. Internal process 
3. Learning and Growth 
4. Customer 

1. Functional testing test cases

1. Does the application work as intended when starting and stopping?  
2. Does the app work accordingly on different mobile and operating system versions?
3. Does the app behave accordingly in the event of external interruptions?
4. (i.e. receiving SMS, minimized during an incoming phone call, etc.)
5. Can the user download and install the app with no problem?
6. Can the device multitask as expected when the app is in use or running in the background?
7. Applications work satisfactorily after installing the app.
8. Do social networking options like sharing, publishing, etc. work as needed?
9. Do mandatory fields work as required?  Does the app support payment gateway transactions?
10. Are page scrolling scenarios working as expected?
11. Navigate between different modules as expected.
12. Are appropriate error messages received if necessary? 

2. Performance testing test cases

1. Can the app handle the expected cargo volumes?
2. What are the various mobile app and infrastructure bottlenecks preventing the app from performing as expected?
3. Is the response time as expected?  Are battery drain, memory leaks, GPS and camera performance within the required guidelines?
4. Current network coverage able to support the app at peak, medium and minimum user levels?
5. Are there any performance issues if the network changes from / to Wi-Fi and 2G / 3G / 4G?
6. How does the app behave during the intermittent phases of connectivity?
7. Existing client-server configurations that provide the optimum performance level? 

3. Battery usage test cases

1. Mobile app power consumption 
2. User interface design that uses intense graphics or results in unnecessarily high database queries
3. Battery life can allow the app to operate at expected charge volumes
4. Battery  low and high performance requirements
5. Application operation if used when battery is removed Battery usage and data leaks
6. New features and updates do not introduce new battery usage and data 
7. Related:  The secret art of battery testing on Android 

1. The buttons are of a user-friendly size. 
2. The position, style, etc. of the buttons are consistent within the app
3. Icons are consistent within the application
4. The zoom in and out functions work as expected
5. The keyboard can be minimized and maximized easily.
6. The action or touching the wrong item can be easily undone.
7. Context menus are not overloaded.
8. Verbiage is simple, clear and easily visible.
9. The end user can easily find the help menu or user manual in case of need.
10. Related: High impact usability testing that is actually doable
