i want to send data from android SqLite database to my Codeigniter web App controller which take the post data and save it to MySql database
so i made buttn to make this sync task in android app and its code:
public void syncAttendance(View v) {
try
{
/** Retrieving data from database **/
//use cursor to keep all data
//cursor can keep data of any data type
Cursor c=db.rawQuery("select * from mytable", null);
int memNum = 1;
//move cursor to first position
c.moveToFirst();
//fetch all data one by one
do
{
//we can use c.getString(0) here
//or we can get data using column index
String memID = c.getString(c.getColumnIndex("memID"));
String currTime = c.getString(c.getColumnIndex("currTime"));
String dayName = c.getString(c.getColumnIndex("dayName"));
////////////////////////////////////////
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://mywebsite.com/index.php/admin/attendance/scan_qr");
JSONObject json = new JSONObject();
/** try {**/
// JSON data:
json.put("memID", memID);
json.put("currTime", currTime);
json.put("dayName", dayName);
JSONArray postjson=new JSONArray();
postjson.put(json);
// Post the data:
httppost.setHeader("json",json.toString());
httppost.getParams().setParameter("jsonpost",postjson);
// Execute HTTP Post Request
System.out.print(json);
HttpResponse response = httpclient.execute(httppost);
// for JSON:
if(response != null)
{
InputStream is = response.getEntity().getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {

} catch (IOException e) {
e.printStackTrace();
}
}
text = sb.toString();
}
//tv.setText(text);

//////////////////////////////////////////
/** show confirmation toast **/
Toast toast = Toast.makeText(this, memNum + memID + currTime + dayName, Toast.LENGTH_LONG);

/** show confirmation toast **/
Toast toast = Toast.makeText(this, "Synchronization Completed", Toast.LENGTH_LONG);

}
catch(Exception e)
{

}
}
and the php codeigniter controller code is:
public function scan_qr()
{
$json = $_SERVER['HTTP_JSON'];
var_dump($json);
$data = json_decode($json);
var_dump($data);
$memID = $data->memID;
$currTime = $data->currTime;
$dayName = $data->dayName;
$ma7abawy_year = 3;
$data= array(
'member_id' => $memID,
//'points' => $points,
'presence_time' => $currTime,
//'event' => $eventname,
'event_date' => $dayName,
'ma7abawy_year' => $ma7abawy_year
);
$this->db->insert('attendance',$data);
}
i have no exception but nothing is happened
any ideas would be appreciated
I would suggest to use retrofit (see API docs) library to consume the service. Afterwards, see what you get back in the response and it will be a simple matter of saving the data to the sqlite3 db. See example for saving data.
I Have this JSP which just check the username and password and "out.write" 1 or 0 based on true or false.
<%# page import="java.io.*" %>
<%
if(request.getParameter("username").equals("anas") && request.getParameter("password").equals("azeem"))
{
out.write("1");
}
else
out.write("0");
%> </br>
Now my android code is somerhing like this
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_agent_login);
edit_username = (EditText) findViewById(R.id.edit_username);
edit_password = (EditText) findViewById(R.id.edit_password);
btn_login = (Button) findViewById(R.id.btnLogin);
if (android.os.Build.VERSION.SDK_INT > 9) { // must add this code in
// order not to get the
// Exception while executing
// program
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
.permitAll().build();
StrictMode.setThreadPolicy(policy);
}
btn_login.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
username = edit_username.getText().toString();
password = edit_password.getText().toString();
Log.d(TAG, "Username:" + username);
Log.d(TAG, "Password:" + password);
try {
new Thread() {
public void run() {
try {
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://10.0.2.2:8080/MyApp/login.jsp");
List<NameValuePair> pairs = new ArrayList<NameValuePair>(2);
pairs.add(new BasicNameValuePair("username",edit_username.getText().toString()));
pairs.add(new BasicNameValuePair("password",edit_password.getText().toString()));
post.setEntity(new UrlEncodedFormEntity(pairs));
HttpResponse response = client.execute(post);
HttpEntity httpEntity = response.getEntity();
xml = EntityUtils.toString(httpEntity);
Log.d("xml", ""+xml.length()); //To confirm anything is there in the "xml"
} catch (Exception e) {
e.printStackTrace();
}
}
}.start();
} catch (Exception e) {
Log.d("xml", xml.toString());
Log.d("Server", e.toString());
}
try {
if (Integer.parseInt(String.valueOf(xml.charAt(10))) == 1) { //****HERE*******
Toast.makeText(getApplicationContext(), "LoginSuccessful",Toast.LENGTH_SHORT).show();
Intent intent = new Intent(Agent_Login.this,AgentHome.class);
startActivity(intent);
} else {
Toast.makeText(getApplicationContext(),"Invalid Username or Password", Toast.LENGTH_SHORT).show();
edit_password.setText("");
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
}
Now on HERE (in comment) there gives a NullPointerException, which is I think because the xml is empty.
So, my question is how can I get the reply from the JSP in Android. I tested it on PC with an HTML form and its working absolutely fine.
Any help would be greatly appreciated.
A varaible is named xml but it will probably not contain any XML, as far is I can see; you're returning HTML.
Why would the 1 be located at position 10 in the returned string?
You're logging the content of xml; what is its value?
One assumed using the Tumblr API to upload images would be easy. It isn't. (EDIT It is now, see Edit 2 at the end of this entry)
My app is supposed to upload an image to tumblr. I would prefer doing that from a service but for now I use an activity that closes itself as soon as its done uploading. In OnCreate() the user is authenticated:
consumer = new CommonsHttpOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);
// It uses this signature by default
// consumer.setMessageSigner(new HmacSha1MessageSigner());
provider = new CommonsHttpOAuthProvider(REQUEST_TOKEN_URL,ACCESS_TOKEN_URL,AUTH_URL);
String authUrl;
try
{
authUrl = provider.retrieveRequestToken(consumer, CALLBACK_URL);
Log.d(TAG, "Auth url:" + authUrl);
startActivity(new Intent("android.intent.action.VIEW", Uri.parse(authUrl)));
}
This opens a browser activity where the user can add username and passoword and then the app returns to the activity (this is also why I have to use an activity, I don't know how to do this from a service)
Returning from the browser the data is extracted:
Uri uri = context.getIntent().getData();
if (uri != null && uri.toString().startsWith(CALLBACK_URL))
{
Log.d(TAG, "uri!=null");
String verifier = uri.getQueryParameter("oauth_verifier");
Log.d(TAG, "verifier"+verifier);
try
{
provider.setOAuth10a(true);
provider.retrieveAccessToken(consumer, verifier);
Log.d(TAG, "try");
}
catch (Exception e)
{
Log.e(TAG, e.toString());
e.printStackTrace();
}
OAUTH_TOKEN = consumer.getToken();
OAUTH_SECRET = consumer.getTokenSecret();
Most of these two snippets I got from here and they work well.
With these tokens I can now try putting data on tumblr. When I try to add Text this works fine using this method:
private void createText()
{
if(!OAUTH_TOKEN.equals(""))
{
HttpContext context = new BasicHttpContext();
HttpPost request = new HttpPost("http://api.tumblr.com/v2/blog/" + blogname + ".tumblr.com/post");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("type", "text"));
nameValuePairs.add(new BasicNameValuePair("body", "this is just a test"));
try
{
request.setEntity(new UrlEncodedFormEntity(nameValuePairs));
}
catch (UnsupportedEncodingException e1)
{
Log.e(TAG, e1.toString());
e1.printStackTrace();
}
if (consumer == null)
{
consumer = new CommonsHttpOAuthConsumer(OAuthConstants.TUMBR_CONSUMERKEY, OAuthConstants.TUMBR_SECRETKEY);
}
if (OAUTH_TOKEN == null || OAUTH_SECRET == null)
{
Log.e(TAG, "Not logged in error");
}
consumer.setTokenWithSecret(OAUTH_TOKEN, OAUTH_SECRET);
try
{
consumer.sign(request);
}
catch (OAuthMessageSignerException e)
{
}
catch (OAuthExpectationFailedException e)
{
}
catch (OAuthCommunicationException e)
{
}
HttpClient client = new DefaultHttpClient();
//finally execute this request
try
{
HttpResponse response = client.execute(request, context);
HttpEntity responseEntity = response.getEntity();
if (responseEntity != null)
{
Log.d(TAG, "responseEntety!=null");
try
{
Log.d(TAG, EntityUtils.toString(responseEntity));
}
catch (ParseException e)
{

Log.e(TAG, e.toString());
}
catch (IOException e)
{

Log.e(TAG, e.toString());
} // gives me {"meta":{"status":401,"msg":"Not Authorized"},"response":[]} when I try to upload a photo

PostToTumblr.this.finish();
}
As you can see here http://www.tumblr.com/blog/snapnowandroid (at least as of this time) the text "this is just a test" is posted.
However, when I try to post images, it gets strange. Now I have checked around and apparently this is a well known issue with the tumblr API, which has excessively been discussed here and some have solved it in other programming languages (for example here) but I have been unable to repeat those successes.
The method (in its entirety below) has the exact same structure to the above method (that works), the nameValuePairs are just different
The method is given a Bitmap variable called photo:
private void uploadToTumblr(Bitmap photo)
This bitmap is converted into an array:
ByteArrayOutputStream stream = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] bytes = stream.toByteArray();
The nameValuePairs are filled as follows:
nameValuePairs.add(new BasicNameValuePair(URLEncoder.encode("type", enc), URLEncoder.encode("photo", enc)));
nameValuePairs.add(new BasicNameValuePair(URLEncoder.encode("caption", enc), URLEncoder.encode(text, enc)));
nameValuePairs.add(new BasicNameValuePair("data", Base64.encodeToString(bytes, Base64.URL_SAFE)));
The result is a {"meta":{"status":400,"msg":"Bad Request"},"response":{"errors":["Error uploading photo."]}} from the tumblr api.
I have tries encoding the picture differently as discribed in this article but without any changes.
//http://www.coderanch.com/t/526487/java/java/Java-Byte-Hex-String
final char[] hexArray = {'0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F'};
char[] hexChars = new char[bytes.length * 3];
int v;
for ( int j = 0; j < bytes.length; j++ )
{
v = bytes[j] & 0xFF;
hexChars[j * 3] = '%';
hexChars[j * 3 + 1] = hexArray[v >>> 4];
hexChars[j * 3 + 2] = hexArray[v & 0x0F];
}
String s = new String(hexChars);
s = URLEncoder.encode(s, enc);
nameValuePairs.add(new BasicNameValuePair(URLEncoder.encode("data", enc), s));
Here the entire method (without the hex encoding):
private void uploadToTumblr(Bitmap photo)
{
if(!OAUTH_TOKEN.equals(""))
{
ByteArrayOutputStream stream = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] bytes = stream.toByteArray();
String text ="SNAP";
HttpContext context = new BasicHttpContext();
HttpPost request = new HttpPost("http://api.tumblr.com/v2/blog/" + blogname + ".tumblr.com/post");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
String enc = "UTF-8";
try
{
nameValuePairs.add(new BasicNameValuePair(URLEncoder.encode("type", enc), URLEncoder.encode("photo", enc)));
nameValuePairs.add(new BasicNameValuePair(URLEncoder.encode("caption", enc), URLEncoder.encode(text, enc)));
nameValuePairs.add(new BasicNameValuePair("data", Base64.encodeToString(bytes, Base64.URL_SAFE)));
}

Now, while there are several things I am unhappy with (for example that this is done using an activity instead of a service) the big issue here is clearly the problem of uploading images. I am by no means the first to have this problem, so has anyone been able to get this done in java?
Edit 1
Have not made any progress with the problem at hand but created a workaround that might be nice for people who have the same issue. Tumblr offers posting via mail and you can programm android to send emails in the background as shown here. This works very well but you need to ask users to provide their mail account data and the Tumblr-mail Adress to post.
Edit 2
Years have pased and using email is no longer the easy way to do it. With jumblr there is finally a good API for Java that will work on android. OAuth-Authentication is no fun (it never is) but once you get past this, its fantastic.
Now, technically the question of how to do the authentication does not belong here but It's my overly long question, so I'll just paste some code here and if it's not interesting to you just skip it.
This uses a jar called jumblr-0.0.10-jar-with-dependencies.jar

Why don't you use Jumblr the official Java client for Tumblr.
Regards.
You can easily do this using jumblr - Tumblr java client
JumblrClient client = new JumblrClient(Constant.CONSUMER_KEY,Constant.CONSUMER_SECRET);
client.setToken(preferences.getString("token",null), preferences.getString("token_secret", null));
PhotoPost pp = client.newPost(client.user().getBlogs().get(0).getName(),PhotoPost.class);
pp.setCaption(caption);
// pp.setLinkUrl(link);
// pp.setSource(mImage); // String URL
pp.setPhoto(new Photo(imgFile));
pp.save();
This worked for me...
nameValuePairs.add(new BasicNameValuePair(URLEncoder
.encode("type", "UTF-8"),
URLEncoder.encode("photo", "UTF-8")));
Log.e("Tumblr", "Image shareing file path" + filePath);
nameValuePairs.add(new BasicNameValuePair("caption", caption));
nameValuePairs.add(new BasicNameValuePair("source", filePath));`
where filePath is http url.

EDIT : First Upload image to Web Server then get Url and try to Post with uploaded Url or File path. it will work fine sure... :)
I have Service and AsyncTask in it, which due to check updatings on the server. It have to be reexecuted if it get some data and also if it doesn't. So my AsyncTask implementation is :
private class DklabExecute extends AsyncTask<Void, String, Void> {
int count;
Calendar calendar = Calendar.getInstance();
java.util.Date now = calendar.getTime();
java.sql.Timestamp currentTimestamp = new java.sql.Timestamp(now.getTime());
String url = "http://192.168.0.250:81/?identifier=nspid_"+md5(LoginActivity.passUserId)+
",nspc&ncrnd="+Long.toString(currentTimestamp.getTime());
HttpGet rplPost = new HttpGet(url);
protected Void doInBackground(Void... args)
{
Log.i("service count", Integer.toString(count));

If I send some data to the server, it gives me back in JSON format via rpl server. Everything works good, but the problem is when I get some data from the server, AsyncTask reexecuted in onPostExecute() method and it is the same reapeted one or two times data in my list of orders. If I do not reexecute AsyncTask the listening happens only in onStartCommand() method but not permanently. Tell me please how can I implement this in the best manner...
if it's a service there's no reason to use an AsyncTask.
AyncTasks were build to deliver content back on the original thread (normally a UI thread), but services don't have those.
I suggest you use a ScheduledExecutorService instead http://developer.android.com/reference/java/util/concurrent/ScheduledExecutorService.html
private ScheduledExecutorService executor;
// call those on startCommand
executor = Executors.newSingleThreadScheduledExecutor();
executor.scheduleWithFixedDelay(run, 250,3000, TimeUnit.MILLISECONDS);
and have a Runnable doing the work
private Runnable run = new Runnable() {
#Override
public void run() {
// do your network stuff
}
};
and don't forget to cancel everything when your service stops
executor.shutdown();
edit:
or to use a thread in loop you can:
boolean isRunning;
.
// this on your start
Thread t = new Thread(run);
isRunning = true;
t.start();
the runnable
private Runnable run = new Runnable() {
#Override
public void run() {
while(isRunning){
// do your network stuff
}
}
};
and again, don't forget to finish it whenever the service finishes with:
isRunning = false;
