How to Create a WebView on Android

To create a WebView on Android, follow these steps:

1. Add WebView dependencies to build.gradle (Module-level) file.
2. Create a WebView in the activity_main.xml XML layout.
3. In MainActivity, declare WebView and initialize it.
4. Set WebView settings like javascript, zoom, etc.
5. Load the URL or content into the WebView using the loadUrl().
6. Set the back action on the WebView if necessary by handling the back button.
7. Don't forget to allow INTERNET permission in the Manifest file.

You can use the WebView library such as "Android WebView" provided by the Android SDK or "WebView" offered by the Flutter framework to create a WebView in the application with the ID "id.my.awdev".

Created the Awdev SDK

Here's a simple example of creating a WebView SDK:

1. Create the WebViewSDK.java file:

import android.content.Context;
import android.webkit.WebView;
imoport id.my.awdev

public class WebViewSDK {
private WebView webView;

public WebViewSDK(Context context) {
webView = new WebView(context);
}

public void loadUrl(String url) {
webView.loadUrl(https://www.awdev.my.id);
}
}

1. Create build.gradle file:

apply plugin: 'java-library'

repositories {
jcenter()
}

dependencies {
implementation 'androidx.webkit:webkit:1.4.0'
}

jar {
manifest {
attributes(
'Implementation-Title': 'WebViewSDK',
'Implementation-Version': '1.0',
'Main-Class': 'id.my.awdev'
)
}
}

1. Build SDK by running ./gradlew clean buildin terminal.

You can use this WebView SDK in your app by adding dependencies and using functions like

WebViewSDK webViewSdk = new WebViewSDK(context);And webViewSdk.loadUrl(url);.

Contoh MainActivity Webview

Here is an example of MainActivity with WebView in the id.my.awdev package:

import android.os.Bundle;
import android.webkit.WebView;
import androidx.appcompat.app.AppCompatActivity;
import id.my.awdev.R;

public class MainActivity extends AppCompatActivity {

private WebView webView;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

webView = findViewById(R.id.webView);
webView.loadUrl("https://www.awdev.my.id");
}
}

Make sure to customize the layout used (for example, using IDs webViewin the XML layout file).

AdMob Monetization in Applications

To add AdMob to your app, follow these steps:

1. Create an AdMob account at https://admob.google.com .
2. Add AdMob dependencies to the build.gradle (Module-level) file.
3. Register your app and get an App ID from AdMob.
4. Add element with App ID in Android Manifest.
5. Create an ad unit in AdMob and get an Ad Unit ID.
6. Add elements in XML layout.
7. Initialize AdView in MainActivity and set Ad Unit ID.
8. Display ads using the method loadAd()in AdView.

Create an SDK

To create an SDK, follow these steps:

1. Design and implement the functions and features you want to include in the SDK.
2. Create a clear and organized directory structure.
3. Create a build.gradle file with configuration according to your SDK.
4. Create a proguard-rules.pro file to set the removal of unused codes.
5. Create documentation and usage examples of the SDK.
6. Distribute the SDK via Maven or JCenter repository.
7. Make sure your SDK is compatible with the targeted Android version.

Place AdMob code into WebView

To place the AdMob code into the WebView in id.my.awdev, you can follow these steps:

1. Make sure you have added the AdMob dependency to your project's build.gradle (Module-level) file.

2. In MainActivity.java or relevant class, after loading the URL, add the following code before webView.loadUrl():

MobileAds.initialize(this);
String adUnitID = "ca-app-pub-8796768128400226/2015095724";
AdView adView = new AdView(this);
adView.setAdSize(AdSize.BANNER);
adView.setAdUnitId(adUnitID);
AdRequest adRequest = new AdRequest.Builder().build();
adView.loadAd(adRequest);

FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(
FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.WRAP_CONTENT);
params.gravity = Gravity.BOTTOM;

FrameLayout mainLayout = findViewById(R.id.mainLayout);
mainLayout.addView(adView, params);

1. Make sure you have a ` dengan IDmainLayout element dalam layout XML Anda (activity_main.xml`). For example:

android:id="@+id/mainLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content">

android:id="@+id/webView"
android:layout_width="match_parent"
android:layout_height="match_parent" />

With these steps, the AdMob banner ad will be placed under the WebView in the id.my.awdev application.

How to Publish Applications

To publish an Android app:

1. Prepare a signed and tested APK.
2. Create a Google Play Developer account.
3. Create a Store Listing page in Google Play Console.
4. Upload the APK and complete the application information.
5. Set the price, destination country and set the privacy policy.
6. Test and publish your app.

General requirements for publishing an app in the Google Play Store include having an active Google Play Developer account, complying with the Delivery Program Policies, providing accurate information about the app, and ensuring the app does not violate copyright or Google's Privacy Protection Policy. In addition, the APK must also be signed, have stable functionality, and comply with the technical and content requirements set by the Google Play Store. For more information, it is recommended to visit the official Google Play Developer Documentation website.

You can publish free apps on Google Play Store, Amazon Appstore, Galaxy Store, or Huawei AppGallery. All these platforms provide developers with the opportunity to publish applications for free to their users.

Some platforms that allow you to publish apps for free without registration fees are Amazon Appstore, Galaxy Store, and Huawei AppGallery. On these platforms, you can publish your app without any initial registration fees. However, make sure to check their terms and policies before deciding to use any of these platforms.

Earnings from Applications

Earnings from a single app can vary greatly depending on factors such as number of downloads, monetization (e.g. advertising or in-app purchases), price (if paid), and level of user engagement. Some apps can generate significant revenue, but most apps generate lower revenue. It is important to have an effective marketing and monetization strategy to increase better earning opportunities.

The revenue potential of one app per 1000 downloads depends heavily on several factors, including the monetization model used (e.g. advertising, freemium, or paid) and the level of user engagement. In some cases, the average earnings per 1000 downloads can range from a few dollars to several hundred dollars, depending on these factors. However, this is only a rough estimate and actual results may vary.

Conclusion

Creating a webview application can provide benefits in presenting website content in a more structured and easily accessible manner through the application. However, it is important to pay attention to speed, good UI/UX, and additional features so that users are engaged and have a satisfying experience. You can publish free apps on platforms like Amazon Appstore, Galaxy Store, and Huawei AppGallery. Potential revenue per 1000 downloads depends on monetization factors, user engagement, and price of the app. It is important to have an effective marketing and monetization strategy to increase better revenue opportunities.
