I have an App that is receiving a video file from another App that is working as a Server. While the App is saving the file received on the socket, the video stream starts playing the file (which is under construction). In the code sample, after I press the btnStream, I press the btnPlay and App runs successfully. However, if the playing rate is greater than the download rate, an error will occur. I want to avoid this case. So I need to have a listener on the Video Playing that will pause the videoview when it predicts that this error will occur. I know a solution where if I know the video size, I can counter the bytes received and monitor how many seconds have been buffered and see if the videoview should pause or not. However, is it possible to do it without knowing the video file size? Or having two threads that depends on each other? Thanks.
Note: the VideoView used is a custom one where it can play FileDescriptor.
btnStream.setOnClickListener(new View.OnClickListener() {
#Override

I applied a simple solution that resolved the problem. I am sharing it if anyone is having the same problem. The solution was simply to add an error listener to the videoView that will block the error popups and pauses the video.
mVideoView.setOnErrorListener(new OnErrorListener(){
#Override
public boolean onError(MediaPlayer mp, int what, int extra) {
// TODO Auto-generated method stub
statusText.setText("ERROR PLAYING VIDEO");
mVideoView.pause();
return true;
}
});
pDialog = new ProgressDialog(PlayVideoActivity.this);
pDialog.setTitle("Gajacharitra");
pDialog.setMessage("Buffering video...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
pDialog.show();
try {
// Start the MediaController
mediacontroller.setAnchorView(mVideoView);
// Get the URL from String VideoURL
Uri video = Uri.parse(mVideoURL);
mVideoView.setMediaController(mediacontroller);
mVideoView.setVideoURI(video);
mVideoView.requestFocus();
mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
// Close the progress bar and play the video
public void onPrepared(MediaPlayer mp) {
pDialog.dismiss();
mVideoView.start();
}
});
mVideoView.setOnErrorListener(new MediaPlayer.OnErrorListener() {
#Override
public boolean onError(MediaPlayer mediaPlayer, int i, int i1) {
mVideoView.pause();
pDialog.dismiss();
Toast.makeText(PlayVideoActivity.this, "Can't play this video.", Toast.LENGTH_LONG).show();
finish();
return true;
}
});
} catch (Exception e) {
/*Log.e("Error", e.getMessage());

pDialog.dismiss();

I am doing a validation for fields in an android form.I am checking with server whether the username is available in the server or not.But the main thread goes to the next page before the async checking completes.

I tried using the get method so that the main thread waits till the async class finishes but it didnt work.Please help!!
Check isallValid only in button click , then Do this validation inside your onPostExecute(Void result) method,
if(isUsernameValid)
{
//Toast.makeText(getActivity(),"VALID FORM!!",Toast.LENGTH_LONG).show();
((SignUpPage)getActivity()).getValues().fullname=txtfullname.getText().toString().trim();
((SignUpPage)getActivity()).getValues().dob=txtdob.getText().toString().trim();
int id=radiogender.getCheckedRadioButtonId();
RadioButton rb=(RadioButton) view.findViewById(id);
String gender=rb.getText().toString();
((SignUpPage)getActivity()).getValues().gender=gender;
int id1=radiomarital.getCheckedRadioButtonId();
RadioButton rb1=(RadioButton) view.findViewById(id1);
String marital_status=rb1.getText().toString();
((SignUpPage)getActivity()).getValues().marital_status=marital_status;
((SignUpPage)getActivity()).getValues().occupation=txtoccupation.getText().toString().trim();
((SignUpPage)getActivity()).getValues().username=txtusername.getText().toString().trim();
((SignUpPage)getActivity()).getValues().password=txtpassword.getText().toString().trim();
((SignUpPage)getActivity()).selectFragment(1);
}
now it will work.................
Do not use get() to call the AsyncTask, it hangs your UI.
So call your AsyncTask like,
String userName = txtusername.getText().toString().trim();
new validateusername().execute(userName); // pass the String from EditText, as you cannot interact with UI in doInBackground
Modify your AsyncTask like
public class validateusername extends AsyncTask<String,Void,String>
{
#Override
protected String doInBackground(String... arg0) {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(URL);
List<NameValuePair> pairs = new ArrayList<NameValuePair>();
pairs.add(new BasicNameValuePair("username",arg0[0])); // arg0[0] is the username passed from AsyncTask call
try {
httppost.setEntity(new UrlEncodedFormEntity(pairs));
response = httpclient.execute(httppost);
result=responsetostring.getResponseBody(response);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return result;
}
#Override
protected void onPostExecute(String result1) {
try {
jsonobj=new JSONObject(result);
job2=jsonobj.getJSONObject("server_message");
} catch (JSONException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try {
finalresult=job2.getString("username_availability_message");
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
if(finalresult.equals("exist")){
txtusername.setError("Username exsists!");
isUsernameValid=false;
}
else if(finalresult.equals("available"))
{
isUsernameValid=true;
}
if(txtfullname.getText().toString().trim().length()==0)
{
txtfullname.requestFocus();
txtfullname.setError("Field required");
isallValid=false;
}
if(txtdob.getText().toString().trim().length()==0)
{
txtdob.requestFocus();
txtdob.setError("Field required");
isallValid=false;
}
if(txtoccupation.getText().toString().trim().length()==0)
{
txtoccupation.requestFocus();
txtoccupation.setError("Field required");
isallValid=false;
}
if(txtusername.getText().toString().trim().length()<6){
txtusername.requestFocus();
txtusername.setError("Minimum length of 6 characters");
isallValid=false;
}
if(txtpassword.getText().toString().trim().length()==0)
{
txtpassword.requestFocus();
txtpassword.setError("Field required");
isallValid=false;
}
if(txtconfirmpassword.getText().toString().trim().length()==0)
{

((SignUpPage)getActivity()).getValues().fullname=txtfullname.getText().toString().trim();

int id=radiogender.getCheckedRadioButtonId();
RadioButton rb=(RadioButton) view.findViewById(id);
String gender=rb.getText().toString();
((SignUpPage)getActivity()).getValues().gender=gender;
int id1=radiomarital.getCheckedRadioButtonId();
RadioButton rb1=(RadioButton) view.findViewById(id1);
String marital_status=rb1.getText().toString();
((SignUpPage)getActivity()).getValues().marital_status=marital_status;

((SignUpPage)getActivity()).getValues().username=txtusername.getText().toString().trim();
((SignUpPage)getActivity()).getValues().password=txtpassword.getText().toString().trim();
((SignUpPage)getActivity()).selectFragment(1);
}
}
onPostExecute(), check the conditions and navigate to next activity.
UPDATE: ok so I kept trying to press send until I received the java.net.SocketException: sendto failed: EPIPE (Broken pipe) exception as a toast message once and then there was no activity once again when I pressed the send button. Meaning I didn't get the exception again.
I have two apps where one acts as the server and the other as a client. I was able to send a message from the server to the client like this
dataOutputStream.writeUTF("hello");
basically as a hardcoded string
but when I added a textfield and a button to the server app and tried listening to the onClick like this
sendChatbtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
try {
dataOutputStream.writeUTF(chatMsg);
} catch (IOException e) {
e.printStackTrace();
Toast.makeText(ServerActivity.this, "An exception occurred: " + e.toString(), Toast.LENGTH_SHORT).show();
// TODO Auto-generated catch block
}
}
});
Absolutely NOTHING happened when I press the SEND button and the client did not receive any message, I don't even get any exception as a toast. By the way I am able to send messages from the client to the server and the server receives the client's messages but the client doesn't get any messages from the server.
The logcat although shows this:

You are not updating the chatMsg string after the onClick, so it initializes as a zero length string, and does not change.
When onClick occurs, you need to get the current string from your TextView:
#Override
public void onClick(View v) {
// add this!!!
chatMsg = chatBoxText.getText().toString();
try {
dataOutputStream.writeUTF(chatMsg);
} catch (IOException e) {
e.printStackTrace();
Toast.makeText(ServerActivity.this, "An exception occurred: " + e.toString(), Toast.LENGTH_SHORT).show();
// TODO Auto-generated catch block
}
}

I am android beginner and trying to fetch pnr status using json here is my code which is not working please help me .
Also tell me which parsing method is goo xml parse or json parse.
When you asking questions, using some more words to describe your problem will always help. If there are really nothing more to say, just copy some random paragraph from internet, but make sure you mark them as dummy text so that people won't pay attention on them.
public class JSON extends Activity {
String completeData="";
TextView tv;
EditText et;
Button bt;
HttpClient client;
JSONObject jsonobj;
final static String URI="http://pnrapi.alagu.net/api/v1.0/pnr/";
String pnr_no=null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_json);
tv=(TextView) findViewById(R.id.textView1);
et=(EditText) findViewById(R.id.editText1);
bt=(Button) findViewById(R.id.button1);
client=new DefaultHttpClient();
}
public void showpnr(View v){
pnr_no=et.getText().toString();
if(pnr_no.equals("")){
Toast.makeText(this, "Enter the Valid Pnr", Toast.LENGTH_LONG).show();
return;
}
GetPNR pnr=new GetPNR();
pnr.execute("train-name");
completeData="";
}
public JSONArray pnr(String username){
JSONArray jarray=null;
try
{
StringBuilder builder=new StringBuilder(URI);
builder.append(username);
HttpGet get=new HttpGet(builder.toString());
HttpResponse response=client.execute(get);
int status =response.getStatusLine().getStatusCode();
if(status==200){
HttpEntity entity=response.getEntity();
String data=EntityUtils.toString(entity);
jarray=new JSONArray(data);
}
else{
Toast.makeText(this, "Error", Toast.LENGTH_LONG).show();
}
}catch(ClientProtocolException e){
e.printStackTrace();
}
catch(IOException e){
e.printStackTrace();
}
catch(JSONException e){
e.printStackTrace();
}
catch(Exception e){
e.printStackTrace();
}
return jarray;
}
JSONObject js_pnr=new JSONObject();
public class GetPNR extends AsyncTask<String, Integer, ArrayList<String>>
{
#Override
protected void onPreExecute() {
// TODO Auto-generated method stub
tv.setText("Loading Pnr status");
super.onPreExecute();
}
#Override
protected ArrayList<String> doInBackground(String... params) {
// TODO Auto-generated method stub
ArrayList<String> al_texts=new ArrayList<String>();
try{
JSONArray data =pnr(pnr_no);
if(data==null){
return null;
}
int count=data.length();
JSONObject jobj=new JSONObject();
for(int i=0;i<count;i++){
jobj=data.getJSONObject(i);
al_texts.add(jobj.getString("train-name").toString());
}
return al_texts;
}catch(JSONException e){
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(ArrayList<String> al_pnrText) {
if(al_pnrText==null){
tv.setText("Pnr not found");
return;
}
for(String string:al_pnrText){
completeData+=string+System.getProperty("line.seperator")
+System.getProperty("line.seperator");
}
tv.setText("pnr status:"+System.getProperty("line.seperator")+completeData);
}
}
}
Inside your button onclick just write:
bt.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
String details = "";
GetPNR pnrDetails = new GetPNR();
try {
details = pnrDetails.execute(URI+et.getText().toString()).get();
Log.d("train", details);
tv.setText(details);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ExecutionException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
And the Asynctask is like:
public class GetPNR extends AsyncTask<String, Integer, String> {
#Override
protected String doInBackground(String... params) {
// TODO Auto-generated method stub
String al_texts = "";
for(String newUrl:params){
HttpClient client = new DefaultHttpClient();
HttpGet get = new HttpGet(newUrl);
HttpResponse response;
try {
response = client.execute(get);
BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
String webData = "";
while((webData = reader.readLine()) != null){
Log.i("data", webData);
JSONObject myAwway = new JSONObject(webData);
JSONObject data = myAwway.getJSONObject("data");
Log.i("data", data.toString());
JSONObject travelDate = data.getJSONObject("travel_date");
JSONObject from = data.getJSONObject("from");
JSONObject to = data.getJSONObject("to");
JSONObject alright = data.getJSONObject("alight");
JSONObject board = data.getJSONObject("board");
JSONArray passenger = data.getJSONArray("passenger");
al_texts = data.getString("train_name");
Log.i("data", al_texts);
}
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return al_texts;
}
}
here I'm showing/returning only a string(train name).Like this you can show every details .
this is your modified code and working fine.
