PAypal android future payment issues

i am trying to create a future payment flow into my android app. I already send to my server the OaUTH2 authentication in my method sendAuthorizationToServer; My question is, what and how should i do next, i know that i have to implement a http request to set the future payment but the documetns in paypal are using curl. what should i do next?
here is my paypal activity:

Zxing barcode integeration: The constructor IntentIntegrator() is undefined

i'm trying to integrate Zxing library, and use the barcode scanner from my app.
so, downloaded the 2 java files IntentIntegrator and IntentResult, put them into this package:
com.google.zxing.integration
where my app is in this package:
com.example.mindstormsgamepad
the code I'm using in my activity is:
package com.example.mindstormsgamepad;
import com.google.zxing.integration.IntentIntegrator;
import com.google.zxing.integration.IntentResult;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Toast;
import android.widget.Button;
import android.widget.TextView;
/**
* BarcodeScan Activity
*/
public class BarcodeScanActivity extends CommonActivity implements OnClickListener{
/** Debug */
protected String TAG_SUB = "BarcodeScanActivity";
private Button scanBtn;
private TextView formatTxt, contentTxt;
#Override
public void onCreate(Bundle savedInstanceState) {
initTabSub( TAG_SUB );
log_d( "onCreate" );
super.onCreate( savedInstanceState );
/* set the layout on the screen */
View view = getLayoutInflater().inflate( R.layout.activity_barcode_scan, null );
setContentView( view );
/* Initialization of Bluetooth */
initManager( view );
setTitleName( R.string.activity_barcodescan );
initButtonBack();
initInputDeviceManager();
Toast.makeText(BarcodeScanActivity.this, "QR Scan!", Toast.LENGTH_SHORT).show();
/* Initialization of Scanning */
scanBtn = (Button)findViewById(R.id.scan_button);
formatTxt = (TextView)findViewById(R.id.scan_format);
contentTxt = (TextView)findViewById(R.id.scan_content);
scanBtn.setOnClickListener(this);
}
// --- onCreate end ---
/**
* === onResume ===
*/
#Override
public void onResume() {
log_d( "onResume()" );
super.onResume();
startService();
mInputDeviceManager.register();
}
/**
* === onPause ===
*/
#Override
public void onPause() {
log_d( "onPause()" );
super.onPause();
sendStop();
mInputDeviceManager.unregister();
}
#Override
public void onClick(View v) {
// Start Scan
if(v.getId()==R.id.scan_button){
IntentIntegrator scanIntegrator = new IntentIntegrator(this);
scanIntegrator.initiateScan();
}
}
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
//retrieve scan result
IntentResult scanningResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
if (scanningResult != null) {
//we have a result
String scanContent = scanningResult.getContents();
String scanFormat = scanningResult.getFormatName();
formatTxt.setText("FORMAT: " + scanFormat);
contentTxt.setText("CONTENT: " + scanContent);
}else{
Toast toast = Toast.makeText(getApplicationContext(),
"No Barcode data received!", Toast.LENGTH_SHORT);
toast.show();
}
}
}
but I'm getting this error,
The constructor IntentIntegrator(BarcodeScanActivity) is undefined
and
The method initiateScan(Activity) in the type IntentIntegrator is not applicable for the arguments ()
on these lines:
IntentIntegrator scanIntegrator = new IntentIntegrator(this);
scanIntegrator.initiateScan();
I'm new to android programming,
how to solve this problem?
thanks for your help.

Try This :
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.putExtra("SCAN_MODE", "QR_CODE_MODE,PRODUCT_MODE");
startActivityForResult(intent, 0);
For Result Do the code in onActivityResult method
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
Toast.makeText(getActivity(), "result ", 1000).show();
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
//do code here
}
else if (resultCode == RESULT_CANCELED) {
//do code here
}
}

This means your Activity does not ultimately extend android.app.Activity. see what CommonActivity extends. Otherwise maybe you somehow have an old or wrong copy of the IntentIntegrator.

my text-to-speech android app stopped working when i put it in a tab

I have a text-to-speech app and it works perfectly. thing is I have to put it in a tab, and the tabs works fine. But when I put the tts inside the tab, it doesn't work anymore. I already changed class name, layout to view and package, everything else's pretty unchangeable except the variables of course. Layout's fine. And unluckily I really have to put it in a tab. but the worst part is that it doesn't show any errors. Even try catch can't catch anything. So I suppose it's a kind of a logical error, and it sucked all the logic in my head. Lol. I checked the main activity, where this activity is called, and manifest, they're clean. So, here's the code:
package leytocz.add.andriod;
import java.util.Locale;
import android.app.Activity;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class nptab extends Activity implements TextToSpeech.OnInitListener{
private TextToSpeech tts;
private Button btnSpeak;
private EditText txtText;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.nptab);
tts=new TextToSpeech(this,this);
btnSpeak=(Button) findViewById(R.id.btnSpeak);
txtText=(EditText) findViewById(R.id.txtText);
btnSpeak.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
speakOut();
}
});
}
#Override
public void onInit(int status) {
if (status==TextToSpeech.SUCCESS) {
int result=tts.setLanguage(Locale.US);
if (result==TextToSpeech.LANG_MISSING_DATA
|| result==TextToSpeech.LANG_NOT_SUPPORTED) {
Log.e("TTS","This Language is not supported");
} else {
btnSpeak.setEnabled(true);
speakOut();
}
} else {
Log.e("TTS", "Initialization Failed!");
}
}
private void speakOut() {
String text=txtText.getText().toString();
tts.speak(text,TextToSpeech.QUEUE_FLUSH, null);
}
}

Correct.
static TextToSpeech mTTS;
onCreate():
Intent checkIntent = new Intent();
checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
startActivityForResult(checkIntent, MY_DATA_CHECK_CODE);
onActivityResult:
if (requestCode == MY_DATA_CHECK_CODE && !mTTSInitialized)
{
if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS)
{
// success, create the TTS instance
mTTS = new TextToSpeech(this, (OnInitListener) this);
if (mTTS!=null)
mTTSInitialized = true;
}
else
{
// missing data, install it
Intent installIntent = new Intent();
installIntent.setAction(
TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
startActivity(installIntent);
}
}
Getter:
public static TextToSpeech getmTTS() {
return mTTS;
}
All of this is placed in the TabHost itself.

Dont need to write this much code in your activity just write this line alone,i also faced this problem finally i got this solution.
Change this one
tts=new TextToSpeech(this,this); --this is your code
You change like this
tts=new TextToSpeech(getParent(),this);
It will work perfectly for me

Recognizer Intent not able to define its constants

I am using the activity, voicerecognition.java, provided by Google to allow the user to choose a language, talk into the handset, and view what they have just said. It works when I take out all the language constants, but when I put the language options in, I get errors.
For example:
The method getVoiceDetailsIntent(VoiceRecognition) is undefined for the type
EXTRA_SUPPORTED_LANGUAGES cannot be resolved or is not a field
EXTRA_LANGUAGE_PREFERENCE cannot be resolved or is not a field
The method run() of type new Runnable(){} must override a superclass method
I thought I might just need to update the SDK or something but everything is up to date. I have no idea what is wrong since I copied the activity exactly as is on the link provided.

Any help is appreciated

It appears that your project is at a lower API level than level 8. To fix this, if you are using Eclipse, right click on your project and click properties. Choose Android from the menu on the left, and select a different project build target. If you don't find one at level 8 or higher, click on Window -> Android SDK Manager and install one. You can see what features of RecognizerIntent are available at the various API levels here.

Cannot start TTS (Text to Speech)

Ok basically I have everything set up and I have set up my onClick method many times, but this time it is set up in my main.xml file
<Button
android:layout_alignParentRight="true"
android:layout_height="40dip"
android:layout_width="80dip"
android:id="#+id/speak"
android:enabled="true"
android:visible="true"
android:text="Speak" >
</Button>
obviously it has other things to define its layout but that is one of the xml layouts inside my button, and for some reason every time I click on the button, it just closes the entire application, Why is that?
also If I set it up to add a onClickListener then the button just does nothing.
I would set up my onClick listener like this
speak.setOnClickListener(this);
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.speak:
doSpeak();
break;
}
}
and it still doesnt work.... So i just dont know what I am doing wrong

I mean am i not setting the volume or setting or telling it to speak?!?!?, am I not telling it to do something it is supposed to do?..... the volume on my phone is on and the media volume is up, I have an HTC evo 4g so it should work.....
here Ill add another one with utterance and the onClick Method

There are many things mixed up in your code, especially the part where you check the engine with a StartActivityforResult().
Please see this example of a working TTS: http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/TextToSpeechActivity.html
Also you did not assign any ID to the button (apparently?) Could it be, that another button is using the ID?
/edit:
First of all, merge both Activities. If you call onCreate()again, it will override the previous one. Then add implements OnClickListener and replace
speakBtn.setOnClickListener((OnClickListener) this);
with
speakBtn.setOnClickListener(this);
Eclipse will tell you that you need to add an unimplemented method.

If the XML code you copied at the top of your question is all you have to declare that button, then it is missing the id you expect (R.id.speak) in the handler...
I would suggest you add some debug prints in the doButton function see if that gets called correctly before going any further in the text-to-speech and so on.
