I have developed an Android application that launches a Google Translate Activity using the following code:
...
Intent i = new Intent();
i.setAction(Intent.ACTION_VIEW);
i.putExtra("key_text_input", "What time is it?");
i.putExtra("key_text_output", "");
i.putExtra("key_language_from", "en");
i.putExtra("key_language_to", "es");
i.putExtra("key_suggest_translation", "");
i.putExtra("key_from_floating_window", false);
i.setComponent(new ComponentName("com.google.android.apps.translate",
"com.google.android.apps.translate.translation.TranslateActivity"));
startActivityForResult(i, 0);
...
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.i("yoyo", "in onActivityResult()");
// data is null
}
The parent onActivityResult() is called in my application from the Google Translate Activity, but data is null. Therefore, I assume that there is no way to return any translated text from Google Translate back into my application. Is this correct?
Also, if there was a way to do this, would it be a violation of the API's terms of service? Would it still be a violation if using the Google Translate offline language packs/translation?
If a Google developer (employee) happens to see this and could weigh in, I would appreciate it. I'm really looking for an official response.
Thanks!
I also am curious to know if this is possible.
Meanwhile, if you need to translate simple text here a class that wrap the Google Translate Http Service.
I've never used it in a production enviroment (read a released app) becouse I'm not sure if it's legal.
So if a Google (employee) will answer to your question..maybe could let me know if this approach is legal.
For convenience here the simple AsyncTask that wrap the Google Translate Http Service:
import java.io.IOException;
import java.util.Arrays;
import java.util.Collections;
import java.util.Locale;
import java.util.Random;
import org.json.JSONArray;

I want to read html code of arduino web server.
I can make web server simply with from example 4. code is below.
#include <SoftwareSerial.h>
#include "WiFly.h"
#define SSID "yum2"
#define KEY "yum000000"
// check your access point's security mode, mine was WPA20-PSK
// if yours is different you'll need to change the AUTH constant, see the file WiFly.h for avalable security codes
#define AUTH WIFLY_AUTH_WPA2_PSK
int flag = 0;
// Pins' connection
// Arduino WiFly
// 2 <----> TX
// 3 <----> RX
SoftwareSerial wiflyUart(2, 3); // create a WiFi shield serial object
WiFly wifly(&wiflyUart); // pass the wifi siheld serial object to the WiFly class
void setup()
{
wiflyUart.begin(9600); // start wifi shield uart port
Serial.begin(9600); // start the arduino serial port
Serial.println("--------- WIFLY Webserver --------");
// wait for initilization of wifly
delay(1000);
wifly.reset(); // reset the shield
delay(1000);
//set WiFly params
wifly.sendCommand("set ip local 80\r"); // set the local comm port to 80
delay(100);
wifly.sendCommand("set comm remote 0\r"); // do not send a default string when a connection opens
delay(100);
wifly.sendCommand("set comm open *OPEN*\r"); // set the string that the wifi shield will output when a connection is opened
delay(100);
Serial.println("Join " SSID );
if (wifly.join(SSID, KEY, AUTH)) {
Serial.println("OK");
} else {
Serial.println("Failed");
}
delay(5000);
wifly.sendCommand("get ip\r");
char c;
while (wifly.receive((uint8_t *)&c, 1, 300) > 0) { // print the response from the get ip command
Serial.print((char)c);
}
Serial.println("Web server ready");
}
void loop()
{
if(wifly.available())
{ // the wifi shield has data available
if(wiflyUart.find("*OPEN*")) // see if the data available is from an open connection by looking for the *OPEN* string
{
Serial.println("New Browser Request!");
delay(1000); // delay enough time for the browser to complete sending its HTTP request string
// send HTTP header
wiflyUart.println("HTTP/1.1 200 OK");
wiflyUart.println("Content-Type: text/html; charset=UTF-8");
wiflyUart.println("Content-Length: 244"); // length of HTML code

wiflyUart.print("<br/><button>My Button</button>");
wiflyUart.print("</body>");

}
}
}
the web server work well.
I wrote simple android code to read html is below.
package com.example.http;
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
public class MainActivity extends AppCompatActivity {
private TextView tv;
String urlAddress = "192.168.0.10"; // doesn't show
// String urlAddress = "http://www.kma.go.kr/weather/main.jsp#1159068000"; // work well
Handler handler = new Handler();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv = (TextView)findViewById(R.id.textView1);
Button b = (Button)findViewById(R.id.button1);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
loadHtml();
}
});
}
void loadHtml() {
Thread t = new Thread(new Runnable() {
#Override
public void run() {
final StringBuffer sb = new StringBuffer();
try {
URL url = new URL(urlAddress);
HttpURLConnection conn =
(HttpURLConnection) url.openConnection();
if (conn != null) {
conn.setConnectTimeout(2000);
conn.setUseCaches(false);
if (conn.getResponseCode()
== HttpURLConnection.HTTP_OK) {
BufferedReader br
= new BufferedReader(new InputStreamReader
(conn.getInputStream()));
while (true) {
String line = br.readLine();
if (line == null) break;
sb.append(line + "\n");
}
br.close();
}
conn.disconnect();
}
Log.d("test", sb.toString());
handler.post(new Runnable() {
#Override
public void run() {
tv.setText(sb.toString());
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
});
t.start();
}
}
It work very well with String urlAddress = "http://www.kma.go.kr/weather/main.jsp#1159068000";
but it doesn't show when using
String urlAddress = "192.168.0.10"; instead of before one.
the 192.168.0.10 is allocated ip of arduino from DHCP that i can check on serial monitor.
there is any way to read html from arduino web server??
Your urlAddress isn't a URL, it's just an IP address. You should fully qualify the address with the protocol and the path you want to land on, for example:
String urlAddress = "http://192.168.0.10/";
I would expect you're getting a MalformedURLException.
My current code works perfectly fine to get current version from google store,
But is theres away to get both current version and whats new in the same response ?
I want to recommend the user an update if the application is updated on play store and the user still using an older version.
Here's my code below
public class AppVersion extends AsyncTask<String, Void, String> {
private final String packageName;
private final Listener listener;
public interface Listener {
void result(String version);
}
AppVersion(String packageName, Listener listener) {
this.packageName = packageName;
this.listener = listener;
}
#Override
protected String doInBackground(String... params) {
return getPlayStoreAppVersion(String.format("https://play.google.com/store/apps/details?id=%s", packageName));
}
#Override
protected void onPostExecute(String version) {
listener.result(version);
}
#Nullable
private static String getPlayStoreAppVersion(String appUrlString) {
String
currentVersion_PatternSeq = "<div[^>]*?>Current\\sVersion</div><span[^>]*?>(.*?)><div[^>]*?>(.*?)><span[^>]*?>(.*?)</span>",
appVersion_PatternSeq = "htlgb\">([^<]*)</s";
try {
URLConnection connection = new URL(appUrlString).openConnection();
connection.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows; U; WindowsNT 5.1; en-US; rv1.8.1.6) Gecko/20070725 Firefox/2.0.0.6");
try (BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()))) {
StringBuilder sourceCode = new StringBuilder();
String line;
while ((line = br.readLine()) != null) sourceCode.append(line);
// Get the current version pattern sequence
String versionString = getAppVersion(currentVersion_PatternSeq, sourceCode.toString());
if (versionString == null) return null;
// get version from "htlgb">X.X.X</span>
return getAppVersion(appVersion_PatternSeq, versionString);
}
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
#Nullable
private static String getAppVersion(String patternString, String input) {
try {
Pattern pattern = Pattern.compile(patternString);
if (pattern == null) return null;
Matcher matcher = pattern.matcher(input);
if (matcher.find()) return matcher.group(1);
} catch (PatternSyntaxException e) {
e.printStackTrace();
}
return null;
}
}
and to call the method i use
new AppVersion(context.getPackageName(), version ->
Log.d("app version test", String.format("App version: %s", version)
)).execute();
In my opinion this is a bad design for your App. You should not rely on scraping to Play store to show a prompt to the user to upgrade. What if the Play Store decides to change design of their HTML? You could leave all your users in a buggy situation.
A much better solution would be to use something like Firebase Remote Config. Have your app read the minimum allowed version code from this. Then it is completely controllable by you, and you don't even have to write a server - firebase does it for you.
You can get App version from BuildConfig Class:
BuildConfig.VERSION_CODE.toString()
1 more thing i want to clear that you cannot get the app version of published app on playstore..
You can put your version code on your backend server and then check this code with your current app version through api call.
i think this will help you.

here is the url of my php page
enter image description here
And some more information: I have Genymotion installed and also bluestack, and VirtaulBox. Do they confilct about port? I mean could these softwares cause conflicting ports Apache xampp and their ports?
My Xampp was working with Port: 80 as shown in below image. So writing below ip address as http://10.0.2.2:80/ worked for me.
If you have wifi and your computer and real device (mobile) is connected to the same wifi you can use NGROK software tool to run and debug your app in your real device.
Run the ngrok.exe and type ngrok http 80, it will give you an address like the below image.
Just use the url in your app where you use your ip address.
It is best to use.
This answer assumes, that the browser screenshot shows a successful page load. I believe, the error page is a bit more gray.
There might be a firewall issue at hand. Since you are using a non-standard port, the firewall exceptions that are installed with XAMPP might not cover that.
Go to the Windows Firewall Advanced settings -> inbound rules. Now add a rule that allows for traffic on the TCP port 800. Make sure, that you uncheck the public profile so that if you are on a public wifi, nobody will be able to connect to this application.
Now check with a browser from the smartphone, if your PHP Application is accessible.
Hi i have searched the internet and stackoverflow all day without any solution! :(
My problem is:
I have to show some schedules in a app, and the data is stored on a webpage, normally on PC you visit the page, enter your id, and it shows the schedule...
but how do i get to the schedule without interacting with a webview or stuff like that? i have to save some specific html data after login...
i have tired with jsoup, but after login, then the url changes, and i dont know how to get it, therefore i tried with webview, but this didnt work either
please help :)

But it didn't work. The server code is just:
echo 'cbfunc({"query":{"count":1,"created":"2013-08-24T13:38:58Z","lang":"en-US","results": {"quote":{"symbol":"MSFT","AverageDailyVolume":"47950000","Change":"+2.36","DaysLow":"34.00","DaysHigh":"35.20","YearLow":"26.26","YearHigh":"36.43","MarketCapitalization":"289.5B","LastTradePriceOnly":"34.75","DaysRange":"34.00 - 35.20","Name":"Microsoft Corpora","Symbol":"MSFT","Volume":"225493744","StockExchange":"NasdaqNM"}}}})';

You should use:
http://10.0.2.2/21/test03.php
10.0.2.2 is the special alias to your host loopback interface (i.e., 127.0.0.1 on your development machine)
See: Emulator Network Address Space in the official docs
Though you could have added a logcat, this is most likely why your app fails to obtain the content:
static String yahooStackInfo = "http://localhost/21/test03.php";
This tells your android device to try and access itself. Localhost is the device itself. substitute that with the hostname or IP address of your host.
You might need to check firewall settings too...
Update
Updated with the IP in the comment:
static String yahooStackInfo = "http://223.18.60.177/21/test03.php";
