I'm sorry if this is a stupid question, but my knowledge is very limited on this subject. I'm not asking for a complete solution, I just need a little push in the right direction.
I have an adroid tablet with a lot of pdf files on the sdcard. Now I want to make a tool to scan a barcode with the filename and open this pdf file. The barcode will be like test and the corresponding file will be file://sdcard/pdf/test.pdf.
The barcode scanner gives an enter after scanning so I only need a textbox on screen and the enter key to initiate the opening activity. We'd rather not connect this tablet to our network, so it doesn't have an internet connection.
I have tried to make an app for this, but since my android programming skills are pretty limited this didn't work out for me.
Now I am trying to make a web app with either php or javascript. This isn't really working out for me since my experience with either of those is limited as well. Initially I was thinking of an MS Access tool in VBA but since there's no runtime for Android this idea doesn't work out.
I've already searched for a solution, but haven't found anything I could use.
Does anyone have a suggestion on with kind of tool I should use? And perhaps put me in the right direction. For more information, please ask.
UPDATE 1:
Right now I've created a webpage using HTML and JavaScript. My code is as the following:
<!DOCTYPE html>
<html>
<head>
<meta content="text/html; charset=windows-1252" http-equiv="content-type">
<script type="text/javascript">
function clickyClick() {
url = 'file:///mnt/sdcard/documents/instructies/' + document.getElementById("barcode").value + '.pdf'
window.open(url, '_blank');
document.getElementById("barcode").value = "";
}
</script> <title>Open werkinstructie</title>
</head>
<body>
<form><span style="font-weight: bold; font-family: Helvetica,Arial,sans-serif; font-size:50px;">Barcode:</span>
<input autofocus="autofocus" style="font-size:50px" name="barcode" id="barcode"
onkeydown="if (event.which == 13) clickyClick()" type="text"> </form>
<br>
<button style="height: 85px; width: 120px; font-size: 30px; font-weight:bold;"
onclick="clickyClick()">Open</button>
</body>
</html>
Which I open with Firefox on the tablet. For now I can't get it to work using the Barcode scanner or the enter key, the button however does work. This code opens the file in Adobe Reader, which is exactly what I want to do.

In your layout add an EditText as this:
<EditText
android:id="#+id/editText1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
>
<requestFocus />
</EditText>
In your activity add this in onCreate method:
final EditText mEditText = (EditText) findViewById(R.id.editText1);
mEditText.setImeActionLabel("Done", KeyEvent.KEYCODE_ENTER);
EditText.OnEditorActionListener exampleListener = new EditText.OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId,
KeyEvent event) {
Log.d(TAG, "onEditorAction, key="+event.getKeyCode() + " action="+event.getAction());
if (event.getAction() == KeyEvent.KEYCODE_ENTER) {
openPDF(mEditText.toString());
}
return true;
}
};
To open a PDF, install a PDF app from market and in your activity open PDF as this:
private void openPDF(String fileName){
File file = new File("/sdcard/pdf/"+fileName+".pdf");
if (file.exists()) {
Uri path = Uri.fromFile(file);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(path, "application/pdf");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
try {
startActivity(intent);
} catch (ActivityNotFoundException e) {
Toast.makeText(this, "No reader",
Toast.LENGTH_SHORT).show();
}
}

I created a simple app to taking photos that will store in the SURVEYASSIST folder in the SD card. It is working fine in my mobile Redmi 3s prime (Android version Marshmallow 6.0.1), but when I open the app in Redmi Note 5 pro (Oreo 8.1.0) and click on the camera button, the app is crashing. And error code is attaching as seen in the image.
public class MainActivity extends AppCompatActivity {
public static final int CAPTURE_IMAGE_FULLSIZE_ACTIVITY_REQUEST_CODE = 1777;
private DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
public static final String Demo_ImagePath ="/storage/emulated/0/SURVEYASSIST/";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
String imgcurTime = dateFormat.format(new Date());
String _path = Demo_ImagePath + File.separator + imgcurTime + ".jpg";
File file = new File(_path);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));
startActivityForResult(intent, CAPTURE_IMAGE_FULLSIZE_ACTIVITY_REQUEST_CODE);
}
});
}
}
The FileUriExposedException is what is being thrown. From documentation:
The exception that is thrown when an application exposes a file:// Uri to another app.
There's a good article on how to fix this here but I will summarize in case the link goes dead at some point:
Add this to your manifest:
<manifest ...>
<application ...>
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/provider_paths"/>
</provider>
</application>
Create XML file res/xml/provider_paths.xml
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="."/>
</paths>
Change your code:
From:
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));
To:
Uri apkURI = FileProvider.getUriForFile(
this,
this.getApplicationContext()
.getPackageName() + ".provider", file);
intent.setDataAndType(apkURI, "image/*");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
I'm working on maven web application with JSP and Servlets. I have a href which has a applet class call which loads my applet success fully from certain Servlet but on my windows only.

if I load the url separately in my internet browser it works and I can
access the camera. how every not thru the app.
There are two way to implement this feature.
Use native call from webview by javascript method
For more information :
Binding JavaScript code to Android code
Set WebChromeClient in Webview :
For Example:

I am currently working on a Java application that uses a JavaFX webview to display its UI (with HTML/CSS).
Everything is working fine but I have trouble loading a new page in the system. When I do, the communication between the Java and the new page's JavaScript seems to be broken.
Here is my code :
** Broser **
public class Browser extends Region {
final WebView browser = new WebView();
final WebEngine webEngine = browser.getEngine();
public Browser() {
//apply the styles
getStyleClass().add("browser");
// load the web page
webEngine.load(some_url);
JSObject jsobj = (JSObject) webEngine.executeScript("window");

** Bridge **
public class Bridge {
private static Bridge instance = null;
private WebEngine webEngine;
public Bridge () {
}
public static Bridge getInstance() {
if(instance == null){
instance = new Bridge();
}
return instance;
}
public void init(WebEngine webEngine) {
if(this.webEngine == null) {
this.webEngine = webEngine;
}
}
public void btnStartSessionOnClick(String sessionName, String speakerNickname) {
// Load the new page
webEngine.load(some_other_url);
}
}
Whenever the web engine loads a new page, it replaces the DOM, so there is a different window object. The jsobj you define is only set once, so when a new page is loaded it will be pointing to the wrong object. You need to reset this object every time the page loads, which you can do by observing the engine's load state.
Your design doesn't make a whole lot of sense to me: it makes more sense to me to have the window (jsobj) object as part of the Bridge class, rather than the application class. And since the Browser is not a singleton, it doesn't make sense to make the Bridge a singleton (what if you had multiple web views in your application, for example?).
Here's an SSCCE:
package application;
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.TextField;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.HBox;
import javafx.scene.web.WebEngine;
import javafx.scene.web.WebView;
import javafx.stage.Stage;
public class WebViewTest extends Application {
#Override
public void start(Stage primaryStage) {
WebView webView = new WebView();
WebEngine engine = webView.getEngine();
Label output = new Label();
Bridge bridge = new Bridge(engine);
engine.load(getClass().getResource("/resources/First.html").toExternalForm());
Button first = new Button("Load First");
first.setOnAction(e -> engine.load(getClass().getResource("/resources/First.html").toExternalForm()));
Button second = new Button("Load Second");
second.setOnAction(e -> engine.load(getClass().getResource("/resources/Second.html").toExternalForm()));
TextField textField = new TextField();
Button button = new Button("Send");
EventHandler<ActionEvent> handler = e -> {
bridge.execute(result -> output.setText(result.toString()),
"showText", textField.getText());
textField.setText("");
};
button.setOnAction(handler);
textField.setOnAction(handler);
HBox controls = new HBox(5, first, second, textField, button, new Label("Web page says: "), output);
controls.setPadding(new Insets(10));
BorderPane root = new BorderPane(webView, null, null, controls, null);
Scene scene = new Scene(root);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
The Bridge class:
package application;
import java.util.function.Consumer;
import javafx.concurrent.Worker.State;
import javafx.scene.web.WebEngine;
import netscape.javascript.JSObject;
public class Bridge {
private JSObject window ;
public Bridge(WebEngine engine) {
engine.getLoadWorker().stateProperty().addListener((obs, oldState, newState) -> {
if (newState == State.SUCCEEDED) {
window = (JSObject) engine.executeScript("window");
window.setMember("application", this);
}
});
}
public void execute(Consumer<Object> callback, String function, Object... args) {
callback.accept(window.call(function, args));
}
}
And some simple test HTML files, which I have in a resources folder in the root of the classpath.
First.HTML:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>First</title>
<script>
function showText(text) {
document.getElementById("text").innerHTML = text;
return text;
}
</script>
</head>
<body>
<p>This is the first page</p>
Go to the second page
<div id="text"></div>
</body>
</html>
and Second.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Second</title>
<script>
function showText(text) {
document.getElementById("text").innerHTML = text;
return text;
}
</script>
</head>
<body>
<p>This is the second page</p>
Go back to the first page
<div id="text"></div>
</body>
</html>
I have my smart banner working, but Google AdMob ad serving has been disabled to my application
Violation explanation
ADS AND CONTENT OVERLAP: As stated in our program policies, publishers are not permitted to alter the behavior of AdMob ads in any way. This includes placing ads so that they cover any part of the application content or parts of an application covering any portion of the ads. If your app has drop-down menus they are not permitted to cover AdMob ads.....
Appreciate any help I can get, thank you!
