[Q] Tropo SMS Integration In Android Api

I'm building a complete build of Android with tropo: (Google tropo)
Here's my tropo hosted script in javascript:
Code:
if (typeof number == 'undefined') {//IF the call doesn't come from me (there's no variable set)
var callerId=currentCall.callerID;
var textmessage=currentCall.initialText
hangup()
call('(Put your phone number Here', {network: 'SMS'});
//Analyse message and format it for sending
var message = new Array();
var nbMessages=((textmessage.length())/149) ;//.length() ????? why????
var i=0;
for(i=0;i<nbMessages;i++){
message[i]=callerId+textmessage.substr(i*149,149);
say(message[i]);
wait(1000);
}
hangup()
}
else //SENDING PART:number and text are parameters
{
call(number, {network:"SMS"});
say(text);
}
I've used the CM9 source code for the galaxy s2 that I downloaded and builded following this guide: (Google teamhacksung CyanogenMod9 How to build)
For sending, I simply post an HTTP Post request to my tropo app
Here's the code
I modified the SMSManager.java class in android.telephony package
Code:
public void sendTextMessage(
String destinationAddress, String scAddress, String text,
PendingIntent sentIntent, PendingIntent deliveryIntent) {
if (TextUtils.isEmpty(destinationAddress)) {
throw new IllegalArgumentException("Invalid destinationAddress");
}
if (TextUtils.isEmpty(text)) {
throw new IllegalArgumentException("Invalid message body");
}
/* OLD METHOD FOR SMS BY CARRIER
try {
ISms iccISms = ISms.Stub.asInterface(ServiceManager.getService("isms"));
if (iccISms != null) {
iccISms.sendText(destinationAddress, scAddress, text, sentIntent, deliveryIntent);
}
} catch (RemoteException ex) {
// ignore it
}*/
//My new Method via tropo
//Création de l'objet Tropo SMS
TropoSms sms = new TropoSms(destinationAddress, text, sentIntent,deliveryIntent);
sms.send();
}
/**/
public void sendMultipartTextMessage(
String destinationAddress, String scAddress, ArrayList<String> parts,
ArrayList<PendingIntent> sentIntents, ArrayList<PendingIntent> deliveryIntents) {
if (TextUtils.isEmpty(destinationAddress)) {
throw new IllegalArgumentException("Invalid destinationAddress");
}
if (parts == null || parts.size() < 1) {
throw new IllegalArgumentException("Invalid message body");
}
if (parts.size() > 1) {
/*//OLD METHOD FOR SMS CARRIER
try {
ISms iccISms = ISms.Stub.asInterface(ServiceManager.getService("isms"));
if (iccISms != null) {
iccISms.sendMultipartText(destinationAddress, scAddress, parts,
sentIntents, deliveryIntents);
}
} catch (RemoteException ex) {
// ignore it
}*/
//My tropo Method
for(int i=0; i< parts.size();i++){
TropoSms sms = new TropoSms(destinationAddress, parts.get(i), sentIntents.get(i),deliveryIntents.get(i));
sms.send();
}
} else {
PendingIntent sentIntent = null;
PendingIntent deliveryIntent = null;
if (sentIntents != null && sentIntents.size() > 0) {
sentIntent = sentIntents.get(0);
}
if (deliveryIntents != null && deliveryIntents.size() > 0) {
deliveryIntent = deliveryIntents.get(0);
}
sendTextMessage(destinationAddress, scAddress, parts.get(0),
sentIntent, deliveryIntent);
}
}
Here I created the Tropo SMS class in the android.telephony.tropo package
Code:
/**

}
}
return correctedText;
}
}
The sending part works really well. Since it's an API change I can use any SMS App in android and it would work.
But I have a problem with receiving.
My tropo script can only modify the body message of the sms. So when someone send a SMS message to tropo, I prefixed the body message with 10 characters representing it's phone number like this:
original message: "Hello"
new message:"15551231234Hello"
I then send this message to my phone
The modified class SubmitPdu in android.telephony package in the SMSMessage.java file
It's wherethe SMS app get the sms with the createfrompdu() method
Code:
public static SmsMessage createFromPdu(byte[] pdu, String format) {
SmsMessageBase wrappedMessage;
if (FORMAT_3GPP2.equals(format)) {
wrappedMessage = com.android.internal.telephony.cdma.SmsMessage.createFromPdu(pdu);
} else if (FORMAT_3GPP.equals(format)) {
wrappedMessage = com.android.internal.telephony.gsm.SmsMessage.createFromPdu(pdu);
} else {
Log.e(LOG_TAG, "createFromPdu(): unsupported message format " + format);
return null;
}
//Verify here if it comes from TROPO
Log.d("SMSNumberCompare", "Original number:"+wrappedMessage.getOriginatingAddress());
Log.d("SMSNumberCompare", "Tropo number:"+TropoSmsReceiver.TROPO_APP_PHONE_NUMBER);
if(PhoneNumberUtils.compare(wrappedMessage.getOriginatingAddress(), TropoSmsReceiver.TROPO_APP_PHONE_NUMBER)){
Log.d("SMSNumberCompare", "Comparison:"+(PhoneNumberUtils.compare(wrappedMessage.getOriginatingAddress(), TropoSmsReceiver.TROPO_APP_PHONE_NUMBER)));
//Creating TropoReceive Object
TropoSmsReceiver tropo = (TropoSmsReceiver) wrappedMessage; //Downcasting
tropo.formatFromTropo();
//upcasting
wrappedMessage=tropo;
}
return new SmsMessage(wrappedMessage);
}
And here's my TropoSmsReceiver Class which extends the SmsMessageBase class
Code:
package com.android.internal.telephony.tropo;
import android.telephony.PhoneNumberUtils;
import android.telephony.SmsMessage.MessageClass;
import android.util.Log;
import com.android.internal.telephony.SmsMessageBase;
public class TropoSmsReceiver extends SmsMessageBase {
public final static String TROPO_APP_PHONE_NUMBER="###########";
//My new Methods
//this method will format the text to get the parameters transferred from the tropo text
public void formatFromTropo(){
Log.d("TropoFormat", "old address"+this.originatingAddress.address);
this.originatingAddress.address=PhoneNumberUtils.formatNumber(this.messageBody.substring(0, 10), PhoneNumberUtils.FORMAT_NANP );
Log.d("TropoFormat", "new address"+this.originatingAddress.address);
this.messageBody=this.messageBody.substring(11);
Log.d("TropoFormat", "new Body"+this.messageBody);
}
@Override
public MessageClass getMessageClass() {
// TODO Auto-generated method stub
return null;
}

// TODO Auto-generated method stub

}
@Override

return false;
}
}
The interesting part is my new method formatFromTropo()
But I have a problem, it doesn't work.
It builds sucessfully
In the logcat, the debug log says it goes in the if statement (it says Comparison: true and it's placement is in the if)
But when the tropo.formatFromTropo() is called the catlog has no mention of any log declared in the TropoSmsReceiver File. How is that possible? Can you help me?
It's my first android project (app or android Source change) and java project so you can give me many recommendations(and comments) too.
Thank you

[Q] Audio Level Meter

Hello
I'm new to programming and I'm trying to make a java application that will "hear" (not record necessarily) the sound and display how loud is.I'm thinking of converting the sound recordings to numbers,so I can see the difference on the sound levels.I got this code and I added the "getLevel()" method,which returns the amplitude of the current recording,but it's returning -1 everytime.I guess I'm not using it properly. Any ideas how I must call this method?I have to deliver my project in a week,so any help will be much appreciated!
Code:

Ok,I managed to make it capture audio and print on a xls file the timestamp and the value of the current sample,but there is a problem : even I've put some spaces between the time and the value and it seems that they are in different columns,they are actualy on the same column of the xls,it's just expanded and covers the next column (I can put a print screen if you don't understand).How can I make it print the data of time and amplitude in two different columns?Here's my code of the class which creates the file and saves the data on xls :
Code:
package soundRecording;
import java.io.File;
import java.util.Formatter;
public class Save {
static Formatter y;
public static void createFile() {
Date thedate = new Date();
final String folder = thedate.curDate();
final String fileName = thedate.curTime();
try {
String name = "Time_"+fileName+".csv";
y = new Formatter(name);
File nof = new File(name);
nof.createNewFile();
System.out.println("A new file was created.");
}
catch(Exception e) {
System.out.println("There was an error.");
}
}
public void addValues(byte audio) {
Date d = new Date();
y.format("%s " + " %s%n",d.curTime(), audio);
}
public void closeFile() {
y.close();
}
}

[Q] Android: Why are my images coming in so blurry?

I have a Slideshow for the Home Page of my app looks sorta like the Houzz apps Home Page, were it displays a new image daily. But their is one issue I am having is that all of my images are coming in so blurry. I've checked the Resolution and it shouldn't be that blurry for no reason at all. I've tried changing setScaleType such as switching it too CENTER, CENTER_CROP, and Etc... None of those seemed to work. I have tried everything too my knowledge and now I am stuck, Below are some of my relevant source code in order too successfully help me out on this issue.

I have fragment(ThreeFragment) with button(InternalBtn) that have a context menu. Context menu registered with registerForContextMenu(IntBtn); Menu item ClearCacheMet not working. I cannot see neither Toast.makeText().show(); nor Log.d(TAG, "ClearCache"); Common and ITEM_CANCEL items working. I cannot understand why? Please help me.
Toast.makeText(getActivity(), "Called !", Toast.LENGTH_SHORT).show(); not called in ClearCache() function. ClearCacheMet and Common were initialized in other fragment.
public class OneFragment extends Fragment {
public View OneFragmentView = null;
public static final int Common = 25;

Is RecyclerView refreshed when AlertDialog's positive button gets pressed

My MainActivity has a RecyclerView adapter, and data to this RecyclerView is added through a AlertDialog which passes the entered text to the MainActivity. The recycler view gets refreshed somehow when the positive button in the dialog is pressed even though I never call notifyItemInserted() or notifyDatasetChange() after passing the new input. I want to know how this happens, my guess is the recyclerview is somehow refreshed after the positive button is pressed in the dialog box.
Custom AlertDialog Code:
Code:
public class CustomDialog extends AppCompatDialogFragment {
OnNoteAddedListener onNoteAddedListener;
public interface OnNoteAddedListener {
public void onClick(String note);
}
public CustomDialog(OnNoteAddedListener onNoteAddedListener) {
this.onNoteAddedListener = onNoteAddedListener;
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
// Get the layout inflater
final LayoutInflater inflater = getActivity().getLayoutInflater();
final View dialogLayout = inflater.inflate(R.layout.dialog_box, null);
// Inflate and set the layout for the dialog
// Pass null as the parent view because its going in the dialog layout
builder.setView(dialogLayout).setPositiveButton("Ok", new DialogInterface.OnClickListener() {@Override
public void onClick(DialogInterface dialog, int id) {
EditText addNote = dialogLayout.findViewById(R.id.note_text);
String note = addNote.getText().toString();
onNoteAddedListener.onClick(note);
}
}).setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
CustomDialog.this.getDialog().cancel();
}
});
return builder.create();
}
}
Adapter code:
Code:
class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder>
{
private static final String TAG = "RecyclerViewAdapter";
private List<String> notesList;
private Context mContext;
private SendPositionConnector sendPositionConnector;
public interface SendPositionConnector
{
public void sendPosition(int position);
}
public RecyclerViewAdapter(List<String> notesList, Context mContext)
{
this.notesList = notesList;
this.mContext = mContext;
this.sendPositionConnector = (MainActivity)mContext;
}

@Override

{
Log.d(TAG, "onLongClick: long clicked on");
sendPositionConnector.sendPosition(position);
return false;
