[android-developers] Why Can't My Java Server And Android Client Send Any Messages?

2012-07-16 Thread Jeresam515 
for an mmo  I am attempting to create, I have an android client connecting 
to a java server. The android is running on the emulator while the server 
is running straight on my computer. They can connect fine and acknowledge 
the connection but  unless I close either the client or the server the 
other can't recieve the former's message but they can if I do close one.

The server's WorkerThread's Run method:
[code]

public void run() {
try {
InputStream input  = clientSocket.getInputStream();
OutputStream output = clientSocket.getOutputStream();
String returns=;
String s=;
try{
s= inputStreamToString(input).toString();
}
catch(Exception e)
{}
   output.write((HTTP/1.1 200 OK\n\nWorkerRunnable:  +
   this.serverText +  -  +
   ).getBytes());
output.close();
input.close();
} catch (IOException e) {
//report exception somewhere.
e.printStackTrace();
}
}[/code]

The InputStream stringbulider:
[code]
private static StringBuilder inputStreamToString(InputStream is) {
String line = ;
StringBuilder total = new StringBuilder();

BufferedReader rd = new BufferedReader(new InputStreamReader(is));

try {
while ((line = rd.readLine()) != null) {
total.append(line);
}
} catch (Exception e) {
}

return total;}
[/code]

The client's connection method:

[code]  public String sendMessage(String message)
  {
try{ clientSocket = new Socket(10.0.2.2, 9000);

  String modifiedSentence;
  DataOutputStream outToServer = new 
DataOutputStream(clientSocket.getOutputStream());
  BufferedReader inFromServer = new BufferedReader(new 
InputStreamReader(clientSocket.getInputStream()));
  outToServer.writeBytes(message+\n);
  //Stops here
  modifiedSentence = inFromServer.readLine();
  outToServer.close();
  inFromServer.close();
  clientSocket.close();
  Log.v(modifiedSentence, modifiedSentence);
  return modifiedSentence;}
catch(Exception e)
{
return ;}
 
  }[/code]

Thanks, any help will be appreciated.

It does seem to decode the string into bytes(ie: not null), but the image 
that is made from thos bytes by the bitmapfactory is null.

2012-05-22 Thread Jeresam515 


 I don't know how I'd do that, but I have made sure the r used in the 
 decoding is correct by pasting the encoding of the image into there as r. 
 Using an online decoder I decoded it manually and it worked.

[android-developers] How can I send an image from an sql database to an android client?

2012-05-21 Thread Jeresam515 


I'm trying to send an image from an sql database to an android client. I'm 
doing this by way of a php middleman. The code stops working due to a null 
returning of the method below. My php code(works fine to encode image into 
base64(decoded the encoding and it worked)):

?php
//get image
function ob_base64_encode($c) {
$a=base64_encode($c);
$arr = array('base64' = $a);
  return json_encode($arr);
}
$image=resize(48,80,$image);
// And pass its name as a string
ob_start('ob_base64_encode');
imagepng($image);
ob_end_flush();
?

My android code:

public static Bitmap getIm(String IP, int height, int width)
{
ArrayListNameValuePair nameValuePairs = new ArrayListNameValuePair();
//Network queries and gets response(works)
String result = Network.getResponse(IP, nameValuePairs);
//manually decode string since for some reason JSON decode won't work(also 
works)
String r=result.split(:\)[1];
r=r.split(\)[0];
//decode string
byte[] decodedString = Base64.decode(r, Base64.DEFAULT);
Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, 
decodedString.length); 
return decodedByte;
//returns null
}

[android-developers] Android to PHP error- Unidentified Index

2012-05-12 Thread Jeresam515 


when sending data to a php server through android I cam across this error: 
Notice: Undefined index: IT in C:\xampp\htdocs\hello.php on line 4. After 
a few hours of messing around with it I can't solve my issue.

hello.php :

?php
mysql_connect(localhost,user,pass);
mysql_select_db(mmo);
$r=mysql_query(update players set X = '.$_REQUEST['IT'].' where 22=22);
if(!$r)
echo Error in query: .mysql_error();
mysql_close();
header('Refresh: 0.01; URL=http://localhost/hello.php');
?

update method in android:

public void UpdateSeverWithPlayer()
{ListNameValuePair nameValuePairs = new ArrayListNameValuePair();  
nameValuePairs.add(new BasicNameValuePair(IT,3));
try{
 HttpClient httpclient = new DefaultHttpClient();
 HttpPost httppost = new HttpPost(http://10.0.2.2/hello.php;);
 httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

 HttpResponse response = httpclient.execute(httppost);
 HttpEntity entity = response.getEntity();
 is = entity.getContent();
 }catch(Exception e){
 Log.e(log_tag, Error in http connection+e.toString());
}}

I am working on the android emulator and do have the internet permission. 
As always help is greatly appreciated. EDIT 1: It appears the issue is in 
the android and not the php code.

I'm trying to convert a double to a string without notation, and tried
this:

f=
Double.valueOf(c.getString(c.getColumnIndex(NotesDbAdapter.KEY_VALUE)));
NumberFormat formatter = new DecimalFormat(###.##);
However, the value of 7^3^7 is returning as: 558546
opposed to 558545864083284007. As always help would be greatly

The insert row ID code is:

public void createNote(double value, boolean isroot, boolean ispower,
boolean ismultiply, boolean isdivisor, boolean add,
boolean issubtract, double roototpowerval, boolean
paranthaseesend, boolean paranthaseesstart) {

The fetchRow code is:

public Cursor fetchNote(long rowId) throws SQLException {

Cursor mCursor =

mDb.query(true, DATABASE_TABLE, new String[]
{KEY_ISPS,KEY_ISPE,KEY_VALUE,KEY_ISROOT,KEY_REALROWID,KEY_ISPOWER,KEY_POWERORROOTNUMBER,KEY_ISDIVISOR,KEY_ISMULTIPLIER,KEY_ISADD,KEY_ISSUBTRACT},

if (mCursor != null) {
mCursor.moveToFirst();

return mCursor;

}

It can change views here:
public void onClick(View v) {

mDbHelper.createNote(d, false, false, false, false,

However, It doesn't here:
public void onClick(View v) {

[android-developers] Why can't this database make rows?

2012-02-19 Thread Jeresam515 
This database has been unable to make any rows as illustrated by the
fact that testcount always = 0.

Here is my variable initialization:
public static final String KEY_VALUE = x;
public static final String KEY_ISROOT = y;
public static final String KEY_ROWID = _id;
public static final String KEY_REALROWID = _ids;
public static final String KEY_ISPOWER = z;
public static final String KEY_POWERORROOTNUMBER = b;
public static final String KEY_ISDIVISOR = a;
public static final String KEY_ISMULTIPLIER = c;
public static final String KEY_ISADD = d;
public static final String KEY_ISSUBTRACT = e;
public static final String KEY_ISPS = f;
public static final String KEY_ISPE = g;
private static final String TAG = NotesDbAdapter;
private DatabaseHelper mDbHelper;
private SQLiteDatabase mDb;
private static final String DATABASE_NAME = data;
private static final String DATABASE_TABLE = notes;
private static final int DATABASE_VERSION =20;
private static final String DATABASE_CREATE =
   create table  +DATABASE_TABLE+  (
 +KEY_VALUE+  double,  
 +KEY_REALROWID+  integer,  
 +KEY_ROWID+  integer primary key autoincrement,  
+KEY_ISPOWER+  boolean,  
+KEY_ISDIVISOR+  boolean,  
+KEY_ISMULTIPLIER+  boolean,  
+KEY_ISADD+  boolean,  
+KEY_ISSUBTRACT+  boolean,  
+KEY_ISPS+  boolean,  
+KEY_ISPE+  boolean,  
+KEY_POWERORROOTNUMBER+  double,  
 +KEY_ISROOT+  boolean);;

Here is the create row:
 public void createNote(double value, boolean isroot, boolean ispower,
boolean ismultiply, boolean isdivisor, boolean add,
boolean issubtract, double roototpowerval, boolean
paranthaseesend, boolean paranthaseesstart) {
ContentValues initialValues = new ContentValues();
initialValues.put(KEY_VALUE, value);
initialValues.put(KEY_ISROOT, isroot);
initialValues.put(KEY_ISPOWER, ispower);
initialValues.put(KEY_ISMULTIPLIER, ismultiply);
initialValues.put(KEY_ISDIVISOR, isdivisor);
initialValues.put(KEY_ISADD, add);
initialValues.put(KEY_ISSUBTRACT, issubtract);
initialValues.put(KEY_POWERORROOTNUMBER, roototpowerval);
initialValues.put(KEY_ISPE, paranthaseesend);
initialValues.put(KEY_ISPS, paranthaseesstart);
  long r= mDb.insert(DATABASE_TABLE, null, initialValues);
  int a = testCount();
  ContentValues argsa = new ContentValues();
  argsa.put(KEY_VALUE, value);
  argsa.put(KEY_ISROOT, isroot);
  argsa.put(KEY_ISPOWER, ispower);
  argsa.put(KEY_ISMULTIPLIER, ismultiply);
  argsa.put(KEY_ISDIVISOR, isdivisor);

  argsa.put(KEY_ISPS, paranthaseesstart);
  mDb.update(DATABASE_TABLE, argsa, KEY_ROWID + = + r, null);
}

Finally, here is testCount():
public int testCount() {
 Cursor c = mDb.rawQuery(select count(*) from notes, null);
 int tst = 0;
 if (c.moveToNext()) {
 tst = c.getInt(c.getColumnIndex(count(*)));

[android-developers] How should one delete all of the table(but not the table itself without making the thread using that database give an error

2011-12-30 Thread Jeresam515 
So I'm trying to have a menu button to clear my database when it is
pressed, that works fine. However, as soon as new information is sent
to the database the app force closes. How should i stop this? Here is
the clear part:

@Override public boolean onMenuItemSelected(int featureId, MenuItem
item) { switch(item.getItemId()) { case INSERT_ID: //reset just makes
all the variables in the thred reinitialize at base values
mLemonadeMainMenuView.reset(); NotesMade = 0;
mDbHelper.deleteAllNotes(); return true; }

Here is deleteallnotes(): public boolean deleteAllNotes() { return
mDb.delete(DATABASE_TABLE,1, null)  0; }

Here is the new data information:

@Override public boolean onTouchEvent(MotionEvent event)
{ mDbHelper.createNote(event.getX(), event.getY(), 1); NotesMade ++;
mLemonadeMainMenuView.setCoords(NotesMade); return true; }

Finally, here is the recieving end:

while(mNotesMademNoteId) {mNoteId++; Cursor note =
mDbHelper.fetchNote(mNoteId); Float x; Float y; Float size; x =
Float.valueOf(note.getString(note.getColumnIndexOrThrow(NotesDb

=Float.valueOf(note.getString(note.getColumnIndexOrThrow(NotesD

[android-developers] Is my OnTouchEvent() not working correctly?

2011-12-30 Thread Jeresam515 
So I'm making a simple painting app for the Android SDK. However, the
onTouchEvent() is only getting some of the events not all of them(if I
drag my finger across the screen it gets roughly half of the
events(points)) Here is my OnTouchEvent():

@Override
public boolean onTouchEvent(MotionEvent event) {
mDbHelper.createNote(event.getX(), event.getY(), 11);
NotesMade ++;
mLemonadeMainMenuView.setCoords(NotesMade);
return true;
}


private void doDraw(Canvas canvas) {
  canvas.drawColor(Color.TRANSPARENT);
Paint paint = new Paint();
paint.setColor(Color.BLUE);
paint.setStyle(Style.FILL);
int mNoteId = 0;
 while(mNotesMademNoteId)
{mNoteId++;
 Cursor note = mDbHelper.fetchNote(mNoteId);
 Float x;
 Float y;
 Float size;
 x =
Float.valueOf(note.getString(note.getColumnIndexOrThrow(NotesDbAdapter.KEY_X)));
 y=

 size =

[android-developers] How should one delete all of the table(but not the table itself) without making the thread using that database give an error?

2011-12-29 Thread Jeresam515 
So I'm trying to have a menu button to clear my database when it is
pressed, that works fine. However, as soon as new information is sent
to the database the app force closes. How should i stop this? Here is
the clear part:

@Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {
switch(item.getItemId()) {
case INSERT_ID:
//reset just makes all the variables in the thred reinitialize at base
values
mLemonadeMainMenuView.reset();
NotesMade = 0;
mDbHelper.deleteAllNotes();
return true;
}

Here is the new data information:

  @Override
public boolean onTouchEvent(MotionEvent event) {
mDbHelper.createNote(event.getX(), event.getY(), 1);
NotesMade ++;
mLemonadeMainMenuView.setCoords(NotesMade);
return true;
}
Finally, here is the recieving end:

 while(mNotesMademNoteId)
{mNoteId++;
 Cursor note = mDbHelper.fetchNote(mNoteId);
 Float x;
 Float y;
 Float size;
 x =
Float.valueOf(note.getString(note.getColumnIndexOrThrow(NotesDbAdapter.KEY_X)));
 y=
Float.valueOf(note.getString(note.getColumnIndexOrThrow(NotesDbAdapter.KEY_Y)));
 size
=Float.valueOf(note.getString(note.getColumnIndexOrThrow(NotesDbAdapter.KEY_X)));
  canvas.drawCircle(x, y, 1, paint);}
}
