Preparations (UniversalClassifiers need to be downloaded in advance.)

sync project

Open UniversalClassifier

The following page is displayed. If the page is displayed, skip this step.

Beautify the app.

a) Add a model file.

1. Replacing a Model File

2. Open the customized project (mindsporeDemo) trained by using the HMS ToolKit plug-in zero code, and find the model file .ms and tag file in app/src/main/assets.

3. Copy the two files in the same path as app/src/main/assets in this project.

Statement

MinsporeDemo is the demo generated in the previous article. This project and universalClassifier in this document are two projects.

Copy the model file trained by MindsporeDemo to the new app.

In app\src\main\java\com.huawei.mlkit.sample\activitys\CustomActivity, if the model file is generated by Mindspore, you only need to change the name in the red box in the following figure.

b) Change the home screen background.

Place the image to be replaced in app\src\main\res\drawable. If the following page is displayed, click split.

c) Change the background of the button.

Method 1:

For details, see the app\src\main\res\layout\activity_main file.

To invoke the button whose background needs to be changed, use the android:background=”@drawable/file name” button to save the image to the address of the directory where the button is located.

app\src\main\res\drawable

Change the name of the circle_stroke_background image in android:background=”@drawable/circle_stroke_background” to replace the button background.

Method 2

Open

The content is as follows:

You can also add your own Android controls to the app. Modify the configuration according to the preceding figure. For details about how to use the control, see the CSDN.

All buttons and texts can be dragged.

d) Change the text on the main interface.

Find android:text=”MLKIT” in the label in app\src\main\res\layout\activity_main. MLKIT is the set font. Replace it.

Android: textColor: Sets the font color (# + hexadecimal color code).

Android:textSize Sets the font size (positive integer).

Android: testStyle setting fonts

Text STYLE:

Normal: Default

BOLD

ITALIC

BOLD_italic

Process of generating digital signatures and packing APKs that can be released

a) Generate JKS and related configuration

b) Start packing the APK.

Note: If the build varitants button on the left does not exist,

Click this button (ignoring the pop-up dialog box).

Location of the last generated APK that can be released

Putting an Huawei AppGallery on the shelf

a) Log in to the Huawei Developer website.

https://developer.huawei.com/consumer/en/

  1. Click Management Center. If no management center is available, log in to the system first. If no developer is registered

2. After the registration is complete, real-name authentication is required. After logging in to the account, click to access the management center in the upper right corner.

3. You can select individual authentication or company authentication based on your account type.

Note:

l Individual developer authentication: You need to use your ID card number and bank card number for authentication. (Note: If you have already authenticated another account using your real name, you cannot use your own account for authentication again.) For details, see the website page.

l Enterprise developer authentication: For enterprises in China, you need to prepare the unified social credit code, account opening bank, and public account. For enterprises in foreign regions, you need to prepare information such as the legal entity name, company address, business license, and bank account number. For details, see the website requirements. Note that enterprise certification may take about two business days.

Global release: You can determine whether to release your application globally based on your application situation.

Whether to integrate cloud services: MLKit provides cloud and device services. For details, see:

Create an app in AppGallery Connect and select a data storage area based on your region.

Create multiple (a maximum of four) apps with different package names in AppGallery Connect and select the data storage region based on the region where the app is installed. To provide the same service experience in different regions around the world, you are advised to install different apps in four regions (China Mainland, EU/EEA, Russia, and other regions). Different applications differ in data storage locations.

For details about how to create an application, see:

https://developer.huawei.com/consumer/en/doc/development/HMS-Guides/ml-add-agc;
