Barcode Scanner in Fragment

Barcode Scanner in Fragment - android

I'm trying to insert a barcode scanner in my ListFragment and use this tutorial: BarcodeScanner
But if I click on of the two buttons (QR or barcode-scan), it seems that my app doesn't find the downloaded XZing Barcode Scanner. But it is installed! I don't get an issue :-( ...
I think something is wrong in the try-part
Here is the code of my ListFragment:
private Button b1;
private Button b2;
static final String ACTION_SCAN = "com.google.xzing.client.android.SCAN";
#Override
public void onActivityCreated(final Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
b1 = (Button) getView().findViewById(R.id.button_scan_barcode_ean);
b2 = (Button) getView().findViewById(R.id.button_scan_qr_code);
b2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
scanQR(v);
}
});
b1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
scanBar(v);
}
});
}
public void scanBar(View v){
try {
Intent intent = new Intent(ACTION_SCAN);
intent.putExtra("SCAN_MODE", "PRODUCT_MODE");
startActivityForResult(intent, 0);
}
catch (ActivityNotFoundException anfe){
showDialog(getActivity(), "No Scanner Found", "Download a scanner code activity?", "Yes", "No").show();
}
}
public void scanQR(View v){
try {
Intent intent = new Intent(ACTION_SCAN);
intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
startActivityForResult(intent, 0);
}
catch (ActivityNotFoundException anfe){
showDialog(getActivity(), "No Scanner Found", "Download a scanner code activity?", "Yes", "No").show();
}
}
private static AlertDialog showDialog(final Activity act, CharSequence title,
CharSequence message,
CharSequence buttonYes,
CharSequence buttonNo) {
AlertDialog.Builder downloadDialog = new AlertDialog.Builder(act);
downloadDialog.setTitle(title);
downloadDialog.setMessage(message);
downloadDialog.setPositiveButton(buttonYes, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
Uri uri = Uri.parse("market://search?q=pname:" + "com.google.zxing.client.android");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
try {
act.startActivity(intent);
} catch (ActivityNotFoundException anfe) {
}
}
});
downloadDialog.setNegativeButton(buttonNo, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
}
});
return downloadDialog.show();
}
public void onActivityResult(int requestCode, int resultCode, Intent intent){
if (requestCode == 0){
if (resultCode == Activity.RESULT_OK){
String contents = intent.getStringExtra("SCAN_RESULT");
String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
Toast toast = Toast.makeText(getActivity(), "Content:" + contents + "Format" + format, Toast.LENGTH_LONG);
toast.show();
final EditText editTextBarcode = (EditText) getView().findViewById(R.id.editText_barcode);
editTextBarcode.setText(contents);
}
}
}
Any ideas?

There is a typo in your ACTION_SCAN String. You wrote "xzing" instead of "zxing".
The correct String is
"com.google.zxing.client.android.SCAN"

I am trying to create a dialog. After the dialog shows, I should select on-direction or return-direction. If on-direction is selected, it should return true, if return-direction is selected, it should return false. But my dialog does not wait for user-inputs. It disappears after a moment.
I am trying to scan a barcode. after scanning the barcode, I am opening a dialog to get true or false. I will send the scanned result, boolean value to the HTTP SERVER.

How to solve this error ? after selecting image from gallery, app crash error.

This error mostly occurs when the data you are filling in the intent is more than the system is able to transfer through Intent bundle. Check to see the size of all the things you are putting in the bundle. And also check to see that the image you are selecting from gallery is not very large, as the system may not be able to transfer the image from gallery to you app. The camera code is working because the camera app transfers a low-resolution image through the Intent.

Camera app gets closed in android marshmallow

I have created an app in which the user can take pics using their default camera.It works fine in older versions that is till lollipop but when i try to run the app in marshmallow the app gets closed.
So i have added some codes to give permission for the camera app by the user but even it is not working.

I have used an condition to check the phones version.If it is marshmallow then i have given a method name showcamera to do the functions for marshmallow
ShowCamera:

if(checkSelfPermission(android.Manifest.permission.CAMERA)== PackageManager.PERMISSION_GRANTED){
Intent intent = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
ImagefileUri = Uri.fromFile(getFile());
intent.putExtra(MediaStore.EXTRA_OUTPUT, ImagefileUri);
startActivityForResult(intent, CAMERA_PIC_REQUEST);
}else{
if(shouldShowRequestPermissionRationale(Manifest.permission.CAMERA)){
Toast.makeText(this,"Camera permission is needed to show the preview",Toast.LENGTH_SHORT).show();
}
requestPermissions(new String[]{Manifest.permission.CAMERA}, CAMERA_PIC_REQUEST);

Why OnClickListner is not called on clicking?

This is my code for the BASE class, i am inheriting this class to another child class. And from that class i am calling this function ActiveSMSPackage(). My code is perfect which has not kind of any error but yet the method is not called. Can you guys tell me where i am doing wrong?
public class PrepaidSMSBase extends Activity {
private String smsNumber = "";
private String smsPackageName;
private String smsPrice;
private String smsTitle;
private String smsText;
public PrepaidSMSBase(){}
public void setSmsPackageInformation(String smsTitle, String smsPackageName, String smsPrice, String smsNumber, String smsText)
{
this.smsTitle = smsTitle;
this.smsPackageName = smsPackageName;
this.smsPrice = smsPrice;
this.smsNumber = smsNumber;
this.smsText = smsText;
}
public void activeSMSPackage()
{
try
{AlertDialog.Builder builder = new AlertDialog.Builder(PrepaidSMSBase.this);
builder.setTitle(smsTitle);
builder.setMessage("Are you sure you want to active" + PrepaidSMSBase.this.smsPackageName + "in RS: " +
PrepaidSMSBase.this.smsPrice);
builder.setPositiveButton("Activate", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
Uri uri = Uri.parse("smsto:" + smsNumber);
Intent intent = new Intent(Intent.ACTION_SENDTO, uri);
intent.putExtra("sms_body", smsText);
startActivity(intent);
Toast.makeText(getApplicationContext(), "Please click send button to activate desire Package", Toast.LENGTH_LONG).show();
}
});
}catch (ActivityNotFoundException e){
e.printStackTrace();
}
}
Code of Child class is:
public class SMSCheckClass extends PrepaidSMSBase implements View.OnClickListener{
Button checkButton;
public SMSCheckClass(){
setSmsPackageInformation("Test 1","Some Thing","50","660","Sub");
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.checksms);
checkButton = (Button)findViewById(R.id.chkBtn);
checkButton.setOnClickListener(this);
}
#Override
public void onClick(View v)
{
activeSMSPackage();
}

Use this code
{AlertDialog.Builder builder = new AlertDialog.Builder(PrepaidSMSBase.this);
builder.setTitle(smsTitle);
builder.setMessage("Are you sure you want to active" + PrepaidSMSBase.this.smsPackageName + "in RS: " +
PrepaidSMSBase.this.smsPrice);
builder.setPositiveButton("Activate", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
Uri uri = Uri.parse("smsto:" + smsNumber);
Intent intent = new Intent(Intent.ACTION_SENDTO, uri);
intent.putExtra("sms_body", smsText);
startActivity(intent);
Toast.makeText(getApplicationContext(), "Please click send button to activate " + PrepaidSMSBase.this.smsPackageName, Toast.LENGTH_LONG).show();
}
});
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
builder.show();
you just need to add builder.show() in the end of AlertDialog because your function is written inside of AlertDialog and that show() method is used to show AlertDialog

At first, you should show you dialog in activeSMSPackage, please add this code in that method:
builder.show()

Android Send only 1 image via email in app

I have created a "Contact Us" page on my app and the idea is you have the option to send a picture to an already predetermind email address. The problem I have is its taking all the images from the gallery of the phone and sending them all in the email. All I want to do is send one picture. I cant seem to work out what to change to be able to just send one image. Is there anyone who could help?
Here is my code:
public class EmailActivity extends Activity {
Button send;
EditText address, subject, emailtext;
protected static final int CAMERA_PIC_REQUEST = 0;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.email);
send=(Button) findViewById(R.id.emailsendbutton);
address=(EditText) findViewById(R.id.emailaddress);
subject=(EditText) findViewById(R.id.emailsubject);
emailtext=(EditText) findViewById(R.id.emailtext);
send.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if
(!Environment.MEDIA_MOUNTED.equals(Environment.getExternalStorageState()))
{
}
File pngDir = new File(
Environment.getExternalStorageDirectory(),
"Android/data/com.random.jbrefurb/quote");
if (!pngDir.exists())
pngDir.mkdirs();
Uri pngUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{ "random#yahoo.co.uk"});
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject.getText());
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, emailtext.getText());
emailIntent.putExtra(android.content.Intent.EXTRA_STREAM, pngUri);
emailIntent.setType("image/jpeg");
EmailActivity.this.startActivity(Intent.createChooser(emailIntent, "Send mail..."));
}
});
Button back = (Button) findViewById(R.id.button1);
back.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
// fire intent
finish(); // finish current activity
Intent austinIntent = new Intent(view.getContext(),
ContactActivity.class);
startActivityForResult(austinIntent, 0);
}
});
Button camera = (Button) findViewById(R.id.button2);
camera.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
;
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode== 0 && resultCode == Activity.RESULT_OK){
Bitmap x = (Bitmap) data.getExtras().get("data");
((ImageView)findViewById(R.id.imageView1)).setImageBitmap(x);
ContentValues values = new ContentValues();
values.put(Images.Media.TITLE, "title");
values.put(Images.Media.BUCKET_ID, "test");
values.put(Images.Media.DESCRIPTION, "test Image taken");
values.put(Images.Media.MIME_TYPE, "image/jpeg");
Uri uri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI, values);
OutputStream outstream;
try {
outstream = getContentResolver().openOutputStream(uri);
x.compress(Bitmap.CompressFormat.JPEG, 100, outstream);
outstream.close();
} catch (FileNotFoundException e) {
//
}catch (IOException e){
//
}
} }
}
Many thanks in advance

this is code i used in my application try if you need help..
private OnClickListener shareemail=new OnClickListener(){
#Override
public void onClick(View v) {
String address = "your emailaddress";
File filee;
if(address.length()==0)
{
AlertDialog.Builder ab=new AlertDialog.Builder(null);
ab.setMessage("Email Address must not be empty!");
ab.setPositiveButton("OK", new DialogInterface.OnClickListener(){
#Override
public void onClick(DialogInterface dialog, int which) {
}
});
ab.show();
}
else
{
ArrayList<Uri> uris = new ArrayList<Uri>();
Uri u;
Intent emailSession = new Intent(Intent.ACTION_SEND_MULTIPLE);
emailSession.putExtra(Intent.EXTRA_SUBJECT,"your subject");
emailSession.setType("images/*");
emailSession.putExtra(android.content.Intent.EXTRA_EMAIL, new String[] {address});
emailSession.putExtra(android.content.Intent.EXTRA_TEXT,"body text");
FileWriter fw;
BufferedWriter bw;
try{
filee = new File(path of image you want to send);
if(filee.exists())
{
Uri u1 = Uri.fromFile(filee);
uris.add(u1);
emailSession.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);

There is a typo in your ACTION_SCAN String. You wrote "xzing" instead of "zxing". The correct String is "com.google.zxing.client.android.SCAN"
