Customized Camera view in ZXING code reader to show detection

I am using the ZXING QR Code Reader. It is working fine. Detecting codes etc but it does not shows any detection progress(Like red line) while it is scanning the QR Code. Here is Screenshot
And my ScanActivity is,
ScanCode.Java
public class ScanCode extends Activity implements OnClickListener {
Button btnScan;
TextView scanResult;
String text;
Bitmap bmp;
ImageView ivPic;
#Override
public void onCreate(Bundle icicle) {
// TODO Auto-generated method stub
super.onCreate(icicle);
setContentView(R.layout.scan_code);
initViews();
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (v.getId() == R.id.btnScanCode) {
Intent intent = new Intent(
"com.google.zxing.client.android.SCAN");
intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
startActivityForResult(intent, 1);
}
}
private void initViews() {
scanResult = (TextView) findViewById(R.id.scanResult);
ivPic = (ImageView) findViewById(R.id.capturedImg);
btnScan = (Button) findViewById(R.id.btnScanCode);
btnScan.setOnClickListener(this);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1)
if (resultCode == Activity.RESULT_OK) {
String contents = data.getStringExtra("SCAN_RESULT");
String format = data.getStringExtra("SCAN_RESULT_FORMAT");
Toast.makeText(getApplicationContext(), contents,
Toast.LENGTH_SHORT).show();
scanResult.setText(contents);
}// if result_ok
}// onActivityResult
}

I know this answer is bit late but I've just used Zxing barcode/QR-Code scanner recently in my app, if anyone has issue implementing it just follow the steps below (Using Android Studio Official IDE for android).
First add dependencies in app --> build.gradle file
dependencies {
compile 'com.journeyapps:zxing-android-embedded:3.2.0#aar'
compile 'com.google.zxing:core:3.2.1'
}
Activity Usage:
public class MainActivity extends AppCompatActivity {
Button btnScan;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnScan = (Button) findViewById(R.id.btnScan);
btnScan.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
scanBarcode();
}
});
}
private void scanBarcode()
{
new IntentIntegrator(this).initiateScan();
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if(result != null) {
if(result.getContents() == null) {
Log.d("MainActivity", "Cancelled scan");
Toast.makeText(this, "Cancelled", Toast.LENGTH_LONG).show();
} else {
Log.d("MainActivity", "Scanned");
Toast.makeText(this, "Scanned: " + result.getContents(), Toast.LENGTH_LONG).show();
}
}
}
}
If you want to use custom callback and BarCodeView. Zxing provide this functionality simply make layout file
<com.journeyapps.barcodescanner.CompoundBarcodeView
android:id="#+id/barcode_scanner"
android:layout_width="match_parent"
android:layout_height="match_parent">
</com.journeyapps.barcodescanner.CompoundBarcodeView>
<TextView
android:id="#+id/tvScanResult"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Scan Results will be shown here"
android:textColor="#android:color/white"
android:textStyle="bold"/>
In Activity use the following code
public class MainActivity extends AppCompatActivity
{
CompoundBarcodeView barcodeView;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
barcodeView = (CompoundBarcodeView) findViewById(R.id.barcode_scanner);
barcodeView.decodeContinuous(callback);
barcodeView.setStatusText("");
}
#Override
protected void onResume()
{
super.onResume();
barcodeView.resume();
isScanned = false;
}
#Override
protected void onPause()
{
super.onPause();
barcodeView.pause();
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
return barcodeView.onKeyDown(keyCode, event) || super.onKeyDown(keyCode, event);
}
private BarcodeCallback callback = new BarcodeCallback()
{
#Override
public void barcodeResult(BarcodeResult result)
{
if (result.getText() != null)
{
barcodeView.setStatusText(result.getText());
tvscanResult.setText("Data found: " + result.getText());
}
//you can also Add preview of scanned barcode
//ImageView imageView = (ImageView) findViewById(R.id.barcodePreview);
//imageView.setImageBitmap(result.getBitmapWithResultPoints(Color.YELLOW));
}
#Override
public void possibleResultPoints(List<ResultPoint> resultPoints)
{
System.out.println("Possible Result points = " + resultPoints);
}
};
}

Google+ sign in onConnected not called

I am writing a log in fragment that hosts Facebook and Google+ sign in. The fragment is a parent fragment for three fragments with user content that are called with view pager after successful log in. I am storing email and service name in shared preferences upon retrieval from Google or Facebook, and then if successful the view pager is displayed with user fragments. Facebook log in works fine but when I start Google+ sign in it does not get to the onConnected callback method. When I switch to other tabs and return to log in fragment it is somehow triggered and I get user fragments. How can i trigger the onConnected method upon pressing the Google+ sign in button?
to ensure the onActivityResult is called i added this in main activity
MainActivity.java
#Override
protected void onActivityResult(int arg0, int arg1, Intent arg2) {
// TODO Auto-generated method stub
super.onActivityResult(arg0, arg1, arg2);
LoginFragment lf = (LoginFragment)getSupportFragmentManager().findFragmentByTag("Login");
if (lf != null) {
lf.onActivityResult(arg0, arg1, arg2);
}
}

authButton.setVisibility(View.INVISIBLE);
loginButton.setVisibility(View.INVISIBLE);
}
public void onNotLoged() {
mViewPager.setAdapter(null);
mViewPager.setVisibility(View.INVISIBLE);
authButton.setVisibility(View.VISIBLE);
loginButton.setVisibility(View.VISIBLE);
}}
In onConnected method I call mySession object creation (shared preferences) to store the data and onLoged to display user fragments. Why do I have to switch tabs a few times for onConnected to be called?

Because the resolution for the connection failure was started with startIntentSenderForResult and the code REQUEST_CODE_RESOLVE_ERR, you need to capture the result inside Activity.onActivityResult.
protected void onActivityResult(int requestCode, int responseCode, Intent intent) {
if (requestCode == REQUEST_CODE_RESOLVE_ERR && responseCode == RESULT_OK) {
mConnectionResult = null;
mPlusClient.connect();
}
}
So in your case you should call mPlusClient.connect(); in LoginFragment onActivityResult after all needed checks.

restore functionality in InApp android

I have implemented Inapp Billing in my app. For that i have used buttons. when i click button it goes to the purchase activity and it purchases the product. once it purchases the product the button will be invisible. and the other button will be visible which will allow the user to open the product. It is all happening perfectly.But when i reopen the app again the button for purchase is visible . i do not want the button to be visible once it is purchased. how to make the button invisible once it is used for successful purchase.

If you are using the API version 3 you can call getPurchases() method at the onCreate().
This method returns the current un-consumed products owned by the user.
That means if your product is un-consumable, i.e, user will only buy it once then you will have your necessary info right here.
Can't explain how to do it better than in official documentation. Take a look at the Querying for Purchased Items topic to have a code example.
Basically you will receive a list of ownedSkus (owned product ID's) and all you have to do is a loop over this list and make your buttons invisible/ visible.
Let me know if this what you was looking for :)

Facebook api not working in my emulator?

I have implemented login with facebook in my project.
The code is below:
public class login extends Activity{
ImageView fbtn;
private SharedPreferences mPrefs;
static Facebook facebook = new Facebook("271089732997803");
String access_token;
long expires;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.yf_login1);
mPrefs = getPreferences(MODE_PRIVATE);
access_token = mPrefs.getString("access_token", null);
expires = mPrefs.getLong("access_expires", 0);
fbtn = (ImageView)findViewById(R.id.fbtn);
fbtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(access_token != null) {
facebook.setAccessToken(access_token);
Log.v("access_token", access_token);
}
if(expires != 0) {
facebook.setAccessExpires(expires);
Log.i("expires", ""+expires);
}
if (!facebook.isSessionValid()) {
facebook.authorize(login.this,new String[] {}, new DialogListener() {
#Override
public void onComplete(Bundle values) {
SharedPreferences.Editor editor = mPrefs.edit();
editor.putString("access_token", facebook.getAccessToken());
editor.putLong("access_expires", facebook.getAccessExpires());
editor.commit();
}
#Override
public void onFacebookError(FacebookError error) {
}
#Override
public void onError(DialogError e) {
}
#Override
public void onCancel() {
}
});
}
else{
startActivity(new Intent(login.this,ChooseTeam.class));
}
}
});
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
facebook.authorizeCallback(requestCode, resultCode, data);
}
#Override
public void onResume() {
super.onResume();
facebook.extendAccessTokenIfNeeded(this, null);
}
Now my question is when i click on the the fb button it will load the progress bar and after 30-40 second it returns the same page.
The most important thing is when i run the same project in my another pc it will run perfectly, opens the dialog of login for the facebook and got the value in my preferences. But in my case i cannot even get the preferences made in my data.
What will be the problem in my emulator?? I am using eclipse galilio and sdk20.

I got the solution actually my antivirus is blocked the internet for the emulator. So i have uninstalled the antivirus and run the app and it works.
Thank you all for helping me out.

Try this....
and use this Permission for Share in Facebook..
private String[] mPermissions={"publish_stream"};
mFb.authorize(SettingActivity.this, mPermissions,new com.fbintegration.Facebook.DialogListener()
{
