this question is how to apply java script by link to webview https://dl.dropboxusercontent.com/s/lmibwymtkebspij/background.js after the page is fully loaded the background should turn green here is a sample code for loading the page
webView = findViewById(R.id.Web);
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebChromeClient(new MyWebChromeClient());
thank you in advance
maybe someone will come in handy load the text of the script into the script variable using get request to link the address of the script like this:
#SuppressLint("StaticFieldLeak")
class ProgressTask extends AsyncTask<String, Void, String> {
#Override
public String doInBackground(String... path) {
try {
content = getContent(path[0]);
} catch (IOException ex) {
content = ex.getMessage();
}
return content;
}
#Override
public void onPostExecute(String content) {
scriptbg = content;
Log.d("debug", scriptbg);
}
public String getContent(String path) throws IOException {
BufferedReader reader = null;
try {
URL url = new URL(path);
HttpsURLConnection c = (HttpsURLConnection) url.openConnection();
c.setRequestMethod("GET");
c.setReadTimeout(10000);
c.connect();
reader = new BufferedReader(new InputStreamReader(c.getInputStream()));
StringBuilder buf = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
buf.append(line + "\n");
}
return (buf.toString());
} finally {
if (reader != null) {
reader.close();
}
}
}
then we apply the script to our webView when the page is fully loaded like this:
public void onPageFinished(WebView view, String url) {
webView.loadUrl("javascript:" + Script);
Log.d("debug", "finish");
}
I'm trying to send some stuff via mail or Bluetooth etc but not working very well.
I would like to see a text like this:
" Respiration Rate: 0 2.0 5.0 16.0 "...
To do that I've implemented a button and Resut.java stuff. When I try to click on the button and I choose e-mail, app open a mail and the text is only "Respiration Rate"
here click-button:
SRR.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
Bundle bundle = new Bundle();
bundle.putDoubleArray("TryThis",plot_array);
sendIntent.putExtras(bundle);
sendIntent.putExtra(Intent.EXTRA_TEXT, "Respiration Rate: " );
sendIntent.setType("text/plain");
startActivity(Intent.createChooser(sendIntent, getResources().getText(R.string.send_to)));
}
});

Does anyone have an idea about it?
what's wrong or missing?
Thanks in advance
From Android official site:
public static final String EXTRA_TEXT
A constant CharSequence that is associated with the Intent, used with
ACTION_SEND to supply the literal data to be sent. Note that this may
be a styled CharSequence, so you must use Bundle.getCharSequence() to
retrieve it.
So you should convert your double array to String first before calling email app.
Step 1: Write a method which convert a double array to a string.
private String convertDoubleArrayToString(double[] array) {
StringBuilder sb = new StringBuilder();
for (double number: array) {
sb.append(number).append(" ");
}
return sb.toString();
}
Step 2: Change your code to
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "Respiration Rate: " + convertDoubleArrayToString(plot_array));
sendIntent.setType("text/plain");
startActivity(Intent.createChooser(sendIntent, getResources().getText(R.string.send_to)));
That's because all you want to show must be part of the EXTRA_TEXT:
sendIntent.putExtra(Intent.EXTRA_TEXT, "EVERYTHING YOU WANT TO PRINT HERE" );
So you have to build a string with your data, then you create the extra with the complete string.
I have an android webapp and its using a different format from the other webview clients I've been using. However, it doesn't execute javascript which is needed for the file upload button. The default chrome browser can handle the uploads but the previous webview clients cannot, Thats why I chose to use this project.
I will give you the whole MainAvivity.java file.

This is a full solution for all android versions, I had a hard time with this too.

}
Also I want to add that the "upload page" like the one in this example, wont work on < 4 versions, since it has an image preview feature, if you want to make it work use a simple php upload without preview.
Update:
Please find the solution for lollipop devices here and thanks for gauntface
Update 2:
Found complete solution for all android devices including marshmallow here see its github project for more.
I have viewpager and there is webview inside, the webview has swipe capability then when I swipe the webview it changes the whole viewpager, but I want if the swipe in the webview is finished then it changes the viewpager here is mycode
Pager adapter
#Override
public int getCount() {
return pageModels.size();
}
#Override
public boolean isViewFromObject(View view, Object object) {
return view==object;
}
#Override
public Object instantiateItem(ViewGroup container, int position) {
View view = LayoutInflater.from(context).inflate(R.layout.singlepage,container,false);
webView = (WebView) view.findViewById(R.id.webview);
webView.getSettings().setJavaScriptEnabled(true);
webView.setScrollContainer(true);
webView.bringToFront();
webView.getSettings().setUseWideViewPort(true);
String readerContent = null;
File f = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+File.separator+"check.html");
Log.d("readerContent",readerContent);
webView.loadUrl("http://192.168.0.108/book");
webView.setWebViewClient(new WebViewClient());
((ViewPager) container).addView(view);
return view;
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
((ViewPager) container).removeView((View)object);
}
public String getString(InputStream i) throws IOException {
ByteArrayOutputStream result = new ByteArrayOutputStream();
byte[] buffer = new byte[1024];
int length;
while ((length = i.read(buffer)) != -1) {
result.write(buffer, 0, length);
}
return result.toString("UTF-8");
}
You need to create custom ViewPager to prevent swipe.
Second, using WebView's javascript bridge to communicate native java code.
Briefly, js code might set your ViewPager swipeable or not.
+) When you inside html page reached end of swipe, call custom js function to notify native viewpager can be swipeable.
I have a android method which one is called from Javascript for getting the selected filepath info from phone gallery. Now i want to send the filepath name to the javascript method but if i return the filepath name from the android function then it will always return the last filepath info not the current one (May be its for callback!) or if i call any javascript method to send the file info after getting the file path then its show on debug console
like that:
05-04 22:07:50.274: ERROR/Web Console(331): ReferenceError: Can't find variable: SetImageFileName at undefined:1
And here is my Code what i have done...

I
s there anybody who can help me on this issue ...
Looks to me like you need to put this line
webview.loadUrl("javascript:SetImageFileName('"+ selectedImagePath +"')");
in a different method which is then called from onActivityResult once your user has selected the picture
