Value getting toasted but not getting in textview?

I am developing the android application in which sever sends the command to client and client side works on command and sends the result.
I am using handler in client side on every 15 sec to write the data on server side.
My problem is i am getting the output from client side and toasted correctly but the value is assigning to Textview first time which comes from client when the second time the value comes its getting toasted correctly but not assigning to Textview
Here my code Goes

I toasted my string in run method of connectthread class
like
Toast.makeText(getApplicationContext(), "messagelog="+msgLog, Toast.LENGTH_LONG).show();
And after that i am assigning the value to the textview
I am getting the correct value in toast.
i am getting the problem at server side near
if(count<5)
{
Toast.makeText(getApplicationContext(), "messagelog="+msgLog, Toast.LENGTH_LONG).show();
contact.setText(msgLog);
}
this code
In 'contact' textview i am setting the value
Thanks in advance

Since you are using msgLog in UIThread,
thus its value replace when this thread repeat run method.
try to append new value on msgLog not just replace it
msgLog="";
while (true) {
if (dataInputStream.available() > 0) {
String newMsg = dataInputStream.readUTF();
msgLog += newMsg;
ServerSocketNew.this.runOnUiThread(new Runnable() {
#Override
public void run() {
// infoIp.setText(msgLog);
// Toast.makeText(getApplicationContext(), "prev="+prev, Toast.LENGTH_LONG).show();
// Toast.makeText(getApplicationContext(), "messagelog="+msgLog, Toast.LENGTH_LONG).show();
Log.e("Number",msgLog);
e2.setText(msgLog+"#"+msgLog);
if(count<5)
{
Toast.makeText(getApplicationContext(), "messagelog="+msgLog, Toast.LENGTH_LONG).show();
// Flags="False";
// contact.setText("");
// contact1.setText("");
//contact1.setText(msgLog2);
contact.setText(msgLog);
}

}

How to create file in internal memory of android so that later i can attach it to email

I want to create file in internal memory of android.
then i have to attach it to email.
please help me.
I dont know where this file is stored.???

Read through http://developer.android.com/guide/topics/data/data-storage.html and if you still have questions, post something more specific.

Its easy and try / follow this, i hope it will help you
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.main);
buttonSend = (Button) findViewById(R.id.buttonSend);

textMessage = (EditText) findViewById(R.id.editTextMessage);
buttonSend.setOnClickListener(new OnClickListener() {

}
Add this line in AndroidManifest.xml file:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-
permission>

Here is the code for Create and Read a file,
public class ReadNWriteFile extends Activity {
final String TEST_STRING = new String("Hello Android");
final String FILE_NAME = "SAMPLEFILE.txt";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView tv = new TextView(this);
fileCreate();
tv.setText(readFile());
setContentView(tv);
}
private void fileCreate() {
try {
OutputStream os = openFileOutput(FILE_NAME, MODE_WORLD_READABLE);
OutputStreamWriter osw = new OutputStreamWriter(os);
osw.write(TEST_STRING);
osw.close();
} catch (Exception e) {
Log.i("ReadNWrite, fileCreate()", "Exception e = " + e);
}
}
private String readFile() {
try {
FileInputStream fin = openFileInput(FILE_NAME);
InputStreamReader isReader = new InputStreamReader(fin);
char[] buffer = new char[TEST_STRING.length()];
// Fill the buffer with data from file
isReader.read(buffer);
return new String(buffer);
} catch (Exception e) {
Log.i("ReadNWrite, readFile()", "Exception e = " + e);
return null;
}
}
}
To get path, /data/data/package_name/yourFile_Name

Progress Download Dialog

How do you implement Progress Download Dialog based on the codes below? My codes downloads images from a specific URL then it saves the image file into SD Card and set the image as wallpaper. I want to show a Progress Download Dialog when the user touches the options menu button setwallpaper().
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.set_wallpaper:
SetWallpaper(image_url);
return true;
default:
return false;
}
}
public void SetWallpaper(String image_url)
{
URL myFileUrl = null;
try
{
myFileUrl = new URL(image_url);
}
catch (MalformedURLException e)
{
e.printStackTrace();
}
Bitmap bmImg = null;
try {
HttpURLConnection conn = (HttpURLConnection) myFileUrl.openConnection();
conn.setDoInput(true);
conn.connect();
//int length = conn.getContentLength();
InputStream is = conn.getInputStream();
bmImg = BitmapFactory.decodeStream(is);
}
catch (IOException e)
{
e.printStackTrace();
}
try {
String path = myFileUrl.getPath();
String idStr = path.substring(path.lastIndexOf('/') + 1);
File filepath = Environment.getExternalStorageDirectory();
File dir = new File (filepath.getAbsolutePath() + "/Wallpaper/");
dir.mkdirs();
String fileName = idStr;
File file = new File(dir, fileName);
FileOutputStream fos = new FileOutputStream(file);
bmImg.compress(CompressFormat.JPEG, 75, fos);
fos.flush();
fos.close();
WallpaperManager wpm = WallpaperManager.getInstance(getBaseContext());
wpm.setBitmap(bmImg);
}
catch (Exception e){
e.printStackTrace();
}
}
My attempt : Caught Exception . Please refer below codes
public class SingleMenuItemActivity extends Activity {
// XML node keys
static final String KEY_TITLE = "title";
static final String KEY_ARTIST = "artist";
static final String KEY_THUMB_URL = "thumb_url";

#Override

}
public class loadImageTask extends AsyncTask<String, Void, Void>
{
//Drawable imgLoad;
URL myFileUrl = null;
Bitmap bmImg = null;
#Override
protected void onPreExecute() {
// TODO Auto-generated method stub

} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
super.onPreExecute();
progressbar.setVisibility(View.VISIBLE);
}
#Override
protected Void doInBackground(String... params) {
// TODO Auto-generated method stub
try {
HttpURLConnection conn = (HttpURLConnection) myFileUrl.openConnection();
conn.setDoInput(true);
conn.connect();
InputStream is = conn.getInputStream();
bmImg = BitmapFactory.decodeStream(is);
}
catch (IOException e)
{
e.printStackTrace();
}
try {
String path = myFileUrl.getPath();
String idStr = path.substring(path.lastIndexOf('/') + 1);
File filepath = Environment.getExternalStorageDirectory();
File dir = new File (filepath.getAbsolutePath() + "/Wallpaper/");
dir.mkdirs();
String fileName = idStr;
File file = new File(dir, fileName);
FileOutputStream fos = new FileOutputStream(file);
bmImg.compress(CompressFormat.JPEG, 75, fos);
fos.flush();
fos.close();
}
catch (Exception e)
{
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(Void result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
if(progressbar.isShown())
{
progressbar.setVisibility(View.GONE);
}
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
Intent in = getIntent();
String image_url = in.getStringExtra(KEY_THUMB_URL);
switch (item.getItemId()) {
case R.id.save_image:
new loadImageTask().execute(image_url);
return true;
default:
return false;
}

Here you can use the AsyncTask for the show the progressbar/dialogbox .
Show the progress bar visible inside the onPreExecute() method. And performs the image loading operations inside the doInBackground() method. Once this operation is done, we will make progress bar invisible and make imageview visible with that loaded image inside the onPostExecute() method.
For more information check this LINK

Try using this
final ProgressDialog dialog = ProgressDialog.show(
YourACtivity.this, "", "Loading...please wait");
new Thread(new Runnable() {
#Override
public void run() {
SetWallpaper(image_url);
if (dialog != null && dialog.isShowing()) {
dialog.dismiss();
}
}
}).start();
}
instead of
SetWallpaper(image_url);
in the onOptionsItemSelected(MenuItem item)
and next use Handlers to handle http://developer.android.com/reference/android/os/Handler.html

How to download file/image from url to your android app

I need my android app to make request to url to download an image from this url
so I have built this class to help me, BUT it didn't work ???
public class MyAsnyc extends AsyncTask<Void, Void, Void> {
public static File file;
InputStream is;
protected void doInBackground() throws IOException {
File path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
file = new File(path, "DemoPicture.jpg");
try{
// Make sure the Pictures directory exists.
path.mkdirs();
URL url = new URL("http://androidsaveitem.appspot.com/downloadjpg");
// Open a connection to that URL.
URLConnection ucon = url.openConnection();
// Define InputStreams to read from the URLConnection.
is = ucon.getInputStream();
} catch (IOException e) {
Log.d("ImageManager", "Error: " + e);
}
}
#Override
protected Void doInBackground(Void... params) {
try {
doInBackground();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
protected void onPostExecute() {
try {
OutputStream os = new FileOutputStream(file);
byte[] data = new byte[is.available()];
is.read(data);
os.write(data);
is.close();
os.close();
// Tell the media scanner about the new file so that it is
// immediately available to the user.
MediaScannerConnection.scanFile(
null,
new String[] { file.toString() },
null,
new MediaScannerConnection.OnScanCompletedListener() {
public void onScanCompleted(String path, Uri uri) {
Log.i("ExternalStorage", "Scanned " + path + ":");
Log.i("ExternalStorage", "-> uri=" + uri);
}
}
);
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
And I have, in the Activity class on onclick(), this function:
public void down(View v) {
// ImageManager ob=new ImageManager();
// ob.DownloadFromUrl("");
new MyAsnyc().execute();
}
Although I have written the permissions in the manfiest.xml
<uses-sdk android:minSdkVersion="7" />
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

try this
public class MyAsnyc extends AsyncTask<Void, Void, Void> {
public static File file;
InputStream is;
protected void doInBackground() throws IOException {
File path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
file = new File(path, "DemoPicture.jpg");
try {
// Make sure the Pictures directory exists.
path.mkdirs();
URL url = new URL("http://androidsaveitem.appspot.com/downloadjpg");
/* Open a connection to that URL. */
URLConnection ucon = url.openConnection();
/*
* Define InputStreams to read from the URLConnection.
*/
is = ucon.getInputStream();
OutputStream os = new FileOutputStream(file);
byte[] data = new byte[is.available()];
is.read(data);
os.write(data);
is.close();
os.close();
} catch (IOException e) {
Log.d("ImageManager", "Error: " + e);
}
}
#Override
protected Void doInBackground(Void... params) {
// TODO Auto-generated method stub
try {
doInBackground();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
protected void onPostExecute() {
try {
// Tell the media scanner about the new file so that it is
// immediately available to the user.
MediaScannerConnection.scanFile(null,
new String[]{file.toString()}, null,
new MediaScannerConnection.OnScanCompletedListener() {
public void onScanCompleted(String path, Uri uri) {
Log.i("ExternalStorage", "Scanned " + path + ":");
Log.i("ExternalStorage", "-> uri=" + uri);
}
});
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

Define these on the top side
Button BtnDownload;
DownloadManager downloadManager;
After, You should write on create inside :
BtnDownload = (Button)findViewById(R.id.button1);
Later, You should write to the button's click event
downloadManager = (DownloadManager)getSystemService(Context.DOWNLOAD_SERVICE);
Uri uri = Uri.parse("your url");
DownloadManager.Request request = new DownloadManager.Request(uri);
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
Long reference = downloadManager.enqueue(request);
Finally, you need to add this onto the application tag to the manifest.xml :
<uses-permission android:name="android.permission.INTERNET"/>

new DownloadImageFromUrlTask().execute(imagePath);
//add glide dependency in app gradle file
compile 'com.github.bumptech.glide:glide:3.7.0'
public class DownloadImageFromUrlTask extends AsyncTask<String, Void, Bitmap> {
String downloadPath = "";
#Override
protected Bitmap doInBackground(String... args) {
try {
downloadPath = args[0];
return BitmapFactory.decodeStream((InputStream) new URL(downloadPath).getContent());
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(Bitmap bitmap) {
if (bitmap != null) {
String photoFileName = downloadPath.substring(downloadPath.lastIndexOf('/') + 1);
String root_Path = Environment.getExternalStorageDirectory().toString();
String saveImagePath = root_Path + "/" + photoFileName;
saveBitmapToJPEGFile(MainActivity.this, bitmap, new File(saveImagePath), 900);
loadImageWithGlide(MainActivity.this, myImageView, saveImagePath);
} else {
myImageView.setImageResource(R.drawable.default_photo);
}
}
}
public static Boolean saveBitmapToJPEGFile(Context ctx, Bitmap theTempBitmap, File theTargetFile, int i) {
Boolean result = true;
if (theTempBitmap != null) {
FileOutputStream out = null;
try {
out = new FileOutputStream(theTargetFile);
theTempBitmap.compress(Bitmap.CompressFormat.JPEG, CommonUtils.JPEG_COMPRESION_RATIO_DEFAULT, out); //kdfsJpegCompressionRatio
} catch (FileNotFoundException e) {
result = false;
e.printStackTrace();
}
if (out != null) {
try {
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
} else {
result = false;
}
return result;
}
public static void loadImageWithGlide(Context theCtx, ImageView theImageView, String theUrl) {
Glide.with(theCtx)
.load(theUrl)
.diskCacheStrategy(DiskCacheStrategy.NONE)
.skipMemoryCache(true)
.into(theImageView);
}

The problem with your code is you have not read the InputStream.
You should try this
Bitmap bitmap = BitmapFactory.decodeStream(is);
return bitmap;
and make the Asynctask return type as Bitmap.
Or,
As you have used that is in postExecute() your doInBackground() should return that InputStream object is. But you are returning void.
Okey.Try this edited Asynctask.
private class MyAsnyc extends AsyncTask <Void,Void,File> {
File file;
#Override
protected File doInBackground( Void... params ) {
InputStream is = null;
File path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
file = new File( path , "Demo Picture.jpg" ) ;
try { // Make sure the Pictures directory exists.path.mkdirs() ; URL url = new URL ( "http: / /androidsaveitem .appspot.com/download.jpg") ; URLConnection ucon = url.openConnection ( ) ;
path.mkdirs();
OutputStream os = new FileOutputStream(file) ;
byte [ ] data = new byte [ is.available ( ) ] ;
is.read ( data ) ; os.write (data );is.close ( ) ; os.close ( ) ;
return file;
}
catch (Exception e){
Log .d ( "ImageManager " , " Error: " + e ) ;
}
return null;
}
protected void onPostExecute (File file) {
try{
MediaScannerConnection.scanFile( null , new String [] {file.toString( ) } , null , new MediaScannerConnection.OnScanCompletedListener ( ) { public void onScanCompleted (String path, Uri uri) {
Log.i ( " External Storage" , " Scanned " + path + " : " ) ; Log.i ( " E x t e r n a l S t o r a g e " , " - > u r i = " + uri ) ; } } ) ;
}catch (Exception e) {
