I have two evaluate java script one is returing a null value and the other is returnng a emptylist[1] when the list size not greater than 0
both of them were giving output in when run in powershell with node on local windows machine
here is the android code
public void ProfileData(String url, AllMediaCallback callback) {
final ArrayList<String>[] arrayOfLists = new ArrayList[3]; // Change the size to match the number of lists you need
arrayOfLists[0] = new ArrayList<>(); // Initialize the first ArrayList
arrayOfLists[1] = new ArrayList<>(); // Initialize the second ArrayList
arrayOfLists[2] = new ArrayList<>(); // Initialize the third ArrayList
AtomicInteger evaluationCounter = new AtomicInteger(); // Define the evaluationCounter here
ExecutorService executor = Executors.newSingleThreadExecutor();
Handler handler = new Handler(Looper.getMainLooper());
webView.loadUrl(url);
// Delayed operation
webView.setWebViewClient(new WebViewClient() {
@Override
public void onPageFinished(WebView view, String url) {
new Handler().postDelayed(() -> webView.evaluateJavascript("javascript: \n" +
" const pressableContainers = document.querySelectorAll('data-pressable-container=\"true\"');\n" +
" const profileImgUrls = [];\n" +
" pressableContainers.forEach(container => {\n" +
" const draggables = container.querySelectorAll('draggable=\"false\"');\n" +
" draggables.forEach(draggable => {\n" +
" const srcValue = draggable.getAttribute('src');\n" +
" profileImgUrls.push(srcValue);\n" +
" });\n" +
" });\n" +
" \n" +
" profileImgUrls;\n", value -> {
Collections.addAll(arrayOfLists[0], value);
// Increase the evaluation counter
evaluationCounter.getAndIncrement();
// Check if both evaluations are done
if (evaluationCounter.get() == 3 && callback != null) {
callback.onAllMediiaStatusRecived(arrayOfLists);
}
}), 2000);
new Handler().postDelayed(() -> webView.evaluateJavascript(
"javascript: \n" +
" const pressableContainers = document.querySelectorAll('data-pressable-container=\"true\"');\n" +
" const profileImgUrls = [];\n" +
" pressableContainers.forEach(container => {\n" +
" const videos = container.querySelectorAll('video');\n" +
" \n" +
" videos.forEach(video => {\n" +
" const srcValue = video.getAttribute('src');\n" +
" profileImgUrls.push(srcValue);\n" +
" });\n" +
" });\n" +
" \n" +
" profileImgUrls;\n", value -> {
Collections.addAll(arrayOfLists[1], value);
// Increase the evaluation counter
evaluationCounter.getAndIncrement();
// Check if both evaluations are done
if (evaluationCounter.get() == 3 && callback != null) {
callback.onAllMediiaStatusRecived(arrayOfLists);
}
}), 2000);
// Ignore this one its not related to evaluatejavascript
executor.execute(new Runnable() {
@Override
public void run() {
try {
Document document = Jsoup.connect(url).get();
Elements metaTags = document.getElementsByTag("meta");
for (Element metaTag : metaTags) {
String property = metaTag.attr("property");
String content = metaTag.attr("content");
if (property.equals("og:description")) {
arrayOfLists[2].add(content);
}
if (property.equals("og:image")) {
content = content.replace("&", "&");
arrayOfLists[2].add(content);
}
}
} catch (IOException e) {
e.printStackTrace();
}
handler.post(() -> {
// Increase the evaluation counter
evaluationCounter.getAndIncrement();
// Check if both evaluations are done
if (evaluationCounter.get() == 3 && callback != null) {
callback.onAllMediiaStatusRecived(arrayOfLists);
}
});
}
});
}
});
}
public interface AllMediaCallback {
void onAllMediiaStatusRecived(ArrayList<String>[] ArrayOfLists);
}
ProfileData(linkUrl, new AllMediaCallback() {
@Override
public void onAllMediiaStatusRecived(ArrayList<String>[] ArrayOfLists) {
if (ArrayOfLists[0].size() > 0) {
for (String strImage : ArrayOfLists[0]) {
Toast.makeText(getApplicationContext(), strImage, Toast.LENGTH_SHORT).show();
}
} else {
Toast.makeText(getApplicationContext(), "Empty List[0]", Toast.LENGTH_SHORT).show();
}
if (ArrayOfLists[1].size() > 0) {
for (String strImage : ArrayOfLists[1]) {
Toast.makeText(getApplicationContext(), strImage, Toast.LENGTH_SHORT).show();
}
} else {
Toast.makeText(getApplicationContext(), "Empty List[1]", Toast.LENGTH_SHORT).show();
}
}
});
and here is node js script , please note in here i have used puppter for loading the webpage , as it is not needed in webviewclient in android
Image.js
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
// Replace 'your_url_here' with the actual URL you want to load
await page.goto('https://www.threads.net/@sagar_v_raval');
// Wait for the content to load (you might need to adjust the selector and waiting time)
await page.waitForSelector('[data-pressable-container="true"]');
const srcValues = await page.evaluate(() => {
const pressableContainers = document.querySelectorAll('[data-pressable-container="true"]');
const srcValues = [];
pressableContainers.forEach(container => {
const draggables = container.querySelectorAll('[draggable="false"]');
draggables.forEach(draggable => {
const srcValue = draggable.getAttribute('src');
srcValues.push(srcValue);
});
});
return srcValues;
});
console.log(srcValues);
await browser.close();
})();
Video.js
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch({ headless: 'new' });
const page = await browser.newPage();
// Replace 'your_url_here' with the actual URL you want to load
await page.goto('https://www.threads.net/@sagar_v_raval');
// Wait for the content to load (you might need to adjust the selector and waiting time)
await page.waitForSelector('[data-pressable-container="true"]');
const srcValues = await page.evaluate(() => {
const pressableContainers = document.querySelectorAll('[data-pressable-container="true"]');
const srcValues = [];
pressableContainers.forEach(container => {
const videos = container.querySelectorAll('video'); // Select video elements with the 'video-class' class
videos.forEach(video => {
const srcValue = video.getAttribute('src');
srcValues.push(srcValue);
});
});
return srcValues;
});
console.log(srcValues);
await browser.close();
})();
from Evaluate Javascript returning empty list , but working in powershell and cmd
