How i can perform barcode scanner in offline mode with using in camera as it can scan barcode and return the number to me?

You can do that BY using Zxing project that provides a standalone Barcode reader application which (via Android's intent mechanism ) can be called by other applications who wish to integrate Barcode scanning.
The Codes for Zxing project are:

/**
* <p>A utility class which helps ease integration with Barcode Scanner via {#link Intent}s. This is a simple
* way to invoke barcode scanning and receive the result, without any need to integrate, modify, or learn the
* project's source code.</p>
*
* <h2>Initiating a barcode scan</h2>
*
* <p>To integrate, create an instance of {#code IntentIntegrator} and call {#link #initiateScan()} and wait
* for the result in your app.</p>
*
* <p>It does require that the Barcode Scanner (or work-alike) application is installed. The
* {#link #initiateScan()} method will prompt the user to download the application, if needed.</p>
*
* <p>There are a few steps to using this integration. First, your {#link Activity} must implement
* the method {#link Activity#onActivityResult(int, int, Intent)} and include a line of code like this:</p>
*
* <pre>{#code
* public void onActivityResult(int requestCode, int resultCode, Intent intent) {
* IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
* if (scanResult != null) {
* // handle scan result
* }
* // else continue with any other code you need in the method
* ...
* }
* }</pre>
*
* <p>This is where you will handle a scan result.</p>
*
* <p>Second, just call this in response to a user action somewhere to begin the scan process:</p>
*
* <pre>{#code
* IntentIntegrator integrator = new IntentIntegrator(yourActivity);
* integrator.initiateScan();
* }</pre>
*
* <p>Note that {#link #initiateScan()} returns an {#link AlertDialog} which is non-null if the
* user was prompted to download the application. This lets the calling app potentially manage the dialog.
* In particular, ideally, the app dismisses the dialog if it's still active in its {#link Activity#onPause()}
* method.</p>
*
* <p>You can use {#link #setTitle(String)} to customize the title of this download prompt dialog (or, use
* {#link #setTitleByID(int)} to set the title by string resource ID.) Likewise, the prompt message, and
* yes/no button labels can be changed.</p>
*
* <p>Finally, you can use {#link #addExtra(String, Object)} to add more parameters to the Intent used
* to invoke the scanner. This can be used to set additional options not directly exposed by this
* simplified API.</p>
*
* <p>By default, this will only allow applications that are known to respond to this intent correctly
* do so. The apps that are allowed to response can be set with {#link #setTargetApplications(List)}.
* For example, set to {#link #TARGET_BARCODE_SCANNER_ONLY} to only target the Barcode Scanner app itself.</p>
*
* <h2>Sharing text via barcode</h2>
*
* <p>To share text, encoded as a QR Code on-screen, similarly, see {#link #shareText(CharSequence)}.</p>
*
* <p>Some code, particularly download integration, was contributed from the Anobiit application.</p>
*
* <h2>Enabling experimental barcode formats</h2>
*
* <p>Some formats are not enabled by default even when scanning with {#link #ALL_CODE_TYPES}, such as
* PDF417. Use {#link #initiateScan(java.util.Collection)} with
* a collection containing the names of formats to scan for explicitly, like "PDF_417", to use such
* formats.</p>

To call Zxing in desired Activity:
//instantiate ZXing integration class
IntentIntegrator scanIntegrator = new IntentIntegrator(this);
//start scanning
scanIntegrator.initiateScan();
To get scanning result by:
if (scanningResult != null) {
//get content from Intent Result
String scanContent = scanningResult.getContents();
//get format name of data scanned
String scanFormat = scanningResult.getFormatName();
}
For more you can see This zxing
hope this help!

Have a look at the Zxing library:
https://github.com/zxing/zxing
There is also a embedded version:
https://github.com/journeyapps/zxing-android-embedded
With add the scanner activity to your Manifest:
<activity
android:name="com.google.zxing.client.android.CaptureActivity"
android:configChanges="orientation|keyboardHidden"
android:windowSoftInputMode="stateAlwaysHidden" >
<intent-filter>
<action android:name="com.google.zxing.client.android.SCAN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
and open it with
Intent intent = new Intent(Intents.Scan.ACTION);
intent.setPackage(this.getPackageName());
//Add any optional extras to pass
intent.putExtra(Intents.Scan.MODE, Intents.Scan.ONE_D_MODE);
//Launch
startActivityForResult(intent, SCAN_REQUEST_CODE);
and grab the results with
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// Check which request we're responding to
if (requestCode == SCAN_REQUEST_CODE) {
// Make sure the request was successful
if (resultCode == RESULT_OK) {
String result = data.getStringExtra(Intents.Scan.RESULT);
...
}
}

Write to file in Android but failing to get an OuputStream

I need to write to a file which is in the assets folder. I must use

you can't write to a file in assets fold.But you can write it to file system.

Automate File transfer to a PAIRED device in android using bluetooth

I'm a newbie in android programming. So, basically I was trying to automate a file transfer from my android phone(2.3.3) to a PAIRED laptop bluetooth...
I can send manually using share--bluetooth--search for paired device and then send it.
But I want to accomplish this automatically.
APP must only be on sender side. (Duh! receiver is laptop)
App code:

mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
if(mBluetoothAdapter == null){}
if(!mBluetoothAdapter.isEnabled()){
Intent enableBluetooth = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBluetooth, 0);
}
Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices();
if(pairedDevices.size() > 0){
for(BluetoothDevice device : pairedDevices){
if(device.getName().equals("HARSHAR-HP")){
mmDevice = device;
mdeviceadd= device.getAddress();

NO error in code... but nothing happens.
file is not transfered.. please someone help me fix the code.. DOnt ask me to see SAMPLE EXAMPLE, Didnt understand how to send file through it.

I'm afraid that way of transferring files is not valid in Android 4+.
Instead, you can use this piece of code, though it will not transfer automatically the file, it prompts the user to select the destination. I don't think it's possible to send files without user authorization anymore, it's a huge security flaw in my opinion.
public void sendFile(String fileName){
Log.d(TAG, "Sending file...");
File dir = Environment.getExternalStorageDirectory();
File manualFile = new File(dir, "/" + fileName);
Uri uri = Uri.fromFile(manualFile);
String type = "application/pdf";
Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
sharingIntent.setType(type);
sharingIntent.setClassName("com.android.bluetooth", "com.android.bluetooth.opp.BluetoothOppLauncherActivity");
sharingIntent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(sharingIntent);
}

How to convert the WAV/OGG file to FLAC file in Android?

EDIT: Incorporated the changed uv001's answer.
I can only find that ICS 4.0 support decoding of FLAC, but encode. I need some encoder to convert wav to flac, but currenty I can't find it. I find there is a jFlac avaible , but I don't know how to use this library, just simply convert the files.
Could anyone give me a hand on it?
Today, I just some idea by myself, with using the JavaFlacEncoder.
and it works for certain bitrates of WAV.
I changed the value into a hard coding value in which it is working now.

Temple, Thanks for the post and the response with the attached code for FLAC conversion. It works as you described with one minor issue.
The FLACFileOutputStream (fout) and the FileInputStream (sin) are not closed at the end of the function. Please update your post/code so others can benefit as well.
finally {
try {
if (sin != null) sin.close();
if (fout != null) fout.close();
} catch (IOException e) {}
}
PS: FLACFileOutputStream fout will need to be promoted to a class variable for this to work.

Change the following line in your code
unencodedSamples -= flac.t_encodeSamples(unencodedSamples, true);
to
unencodedSamples -= flac.t_encodeSamples(unencodedSamples, true,flac.getThreadCount());
