Im trying to save an Audio record from the Microphone, to a File Object, instead of a File. Why? Because i only need to save the record, while the App is active. This is what i tried, using the "Audio Capture" tutorial from developer.android.com
private Button b1;
private Button b2;
private ProgressBar bar;
private MediaRecorder mRecorder = null;
private MediaPlayer mPlayer = null;
private boolean recording = false;
private boolean playing = false;
public AudioRecordDialog(Context context, final MainActivity main) {
super(context);
setTitle(R.string.setupSound);
setContentView(R.layout.audio_record_dialog_layout);
bar = (ProgressBar) findViewById(R.id.progressBar1);
bar.setAlpha(0);
b1 = (Button) findViewById(R.id.button1);
b1.setText(R.string.startButton);
b1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (recording) {
b1.setText(R.string.startButton);
recording = false;
bar.setAlpha(0);
if (mRecorder != null) {
mRecorder.stop();
mRecorder.release();
}
mRecorder = null;
} else {
b1.setText(R.string.stopButton);
recording = true;
bar.setAlpha(1);
mRecorder = new MediaRecorder();
mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
mRecorder.setOutputFile("record.3gp");
try {
mRecorder.prepare();
} catch (IOException e) {
Toast toast = Toast.makeText(getContext(),
"Failed Recording!", Toast.LENGTH_SHORT);
toast.show();
}
mRecorder.start();
}
}
});
b2 = (Button) findViewById(R.id.button2);
b2.setText(R.string.playButton);
b2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (playing) {
b2.setText(R.string.playButton);
playing = false;
if (mPlayer != null)
mPlayer.release();
mPlayer = null;
} else {
b2.setText(R.string.pauseButton);
playing = true;
mPlayer = new MediaPlayer();
try {
mPlayer.setDataSource("record.3gp");
mPlayer.prepare();
mPlayer.start();
} catch (IOException e) {
Toast toast = Toast.makeText(getContext(),
"Failed Playing soundFile!",
Toast.LENGTH_SHORT);
toast.show();
}
}
}
});
But it doesnt work and crashes upon clicking the record-Button.
Here is the logCat.

You should call setAudioEncoder() after setOutputFormat().

I used Android native Sip api to initialize Sip client.Because I am confused to Sip protocol,I read the android developer document about sip and follow it.When I run my application on Nexus5,it work normally,but when I run it on other device like coolpad, it throw NullPointException from SipManager.The following is my code.For some reason,the username,passwd and domain is private.
public static SipManager manager;
public static SipProfile me;
public static String username;
public static String passwd;
public static void initializeSip(Context context) {
System.out.println("initializeSip");
if (manager == null) {
manager = SipManager.newInstance(context);
}
if (me != null) {
closeLocalProfile();
}
username = SharedPreferences.getLoginInfo().getModel().getVos_phone();
passwd = SharedPreferences.getLoginInfo().getModel().getVos_phone_pwd();
try {
if (!(SipManager.isApiSupported(context) && SipManager.isVoipSupported(context))) {
System.out.println("cannot support");
return;
}
System.out.println("isApiSupported="+SipManager.isApiSupported(context));
System.out.println("SipManager="+SipManager.newInstance(context));
SipProfile.Builder builder = new SipProfile.Builder(username, domain);
builder.setPassword(passwd);
me = builder.build();
manager.open(me);
SipRegistrationListener listener = new SipRegistrationListener() {
#Override
public void onRegistering(String localProfileUri) {
System.out.println("Registering with SIP Server");
}
#Override
public void onRegistrationDone(String localProfileUri, long expiryTime) {
System.out.println("Register success");
}
#Override
public void onRegistrationFailed(String localProfileUri, int errorCode, String errorMessage) {
System.out.println("Registeration failed.Please check Settings.");
System.out.println("errorCode="+errorCode);
System.out.println("errorMessage="+errorMessage);
}
};
manager.setRegistrationListener(me.getUriString(),listener);
manager.register(me,3000,listener);
} catch (ParseException e) {
e.printStackTrace();
} catch (SipException e) {
e.printStackTrace();
}
}
The following is my logcat. Most strangely,I find that the api isApiSupported return true and the SipManager object is not null.I cannot find the reason about it.

I am trying to create a class that sets and starts audio recording but as soon as I click the button the app crashes. Iv isolated the problem to where I set the parameters for the MediRecorder.
private void startRec() throws IOException {
if (mrecorder!=null)
mrecorder.release();
mrecorder= new MediaRecorder();
-> mrecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
/*
mrecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
mrecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
mrecorder.setOutputFile(MFILE);
mrecorder.prepare();
mrecorder.start();
*/
}
It crashes when the line with the arrow above the start of the notes is executed. I added the following permission to the manifest as well:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
Any help much appreciated.

Seems an issue of IabHelper. The method queryIntentServices returns a null, instead an empty list.
Try to update the code from this:
Intent serviceIntent = new Intent("com.android.vending.billing.InAppBillingService.BIND");
if (!mContext.getPackageManager().queryIntentServices(serviceIntent, 0).isEmpty()) {
// service available to handle that Intent
mContext.bindService(serviceIntent, mServiceConn, Context.BIND_AUTO_CREATE);
}
else {
// no service available to handle that Intent
if (listener != null) {
listener.onIabSetupFinished(
new IabResult(BILLING_RESPONSE_RESULT_BILLING_UNAVAILABLE,
"Billing service unavailable on device."));
}
}
to this:
Intent serviceIntent = new Intent("com.android.vending.billing.InAppBillingService.BIND");
List<ResolveInfo> intentServices = mContext.getPackageManager().queryIntentServices(serviceIntent, 0);
if (intentServices != null && intentServices.isEmpty() == false) {
// service available to handle that Intent
mContext.bindService(serviceIntent, mServiceConn, Context.BIND_AUTO_CREATE);
}
else {
// no service available to handle that Intent
if (listener != null) {
listener.onIabSetupFinished(
new IabResult(BILLING_RESPONSE_RESULT_BILLING_UNAVAILABLE,

You can't make HTTP requests on the main thread, it would cause the UI to freeze up. So it throws that exception. You need to do it in an AsyncTask or another Thread.
http://developer.android.com/reference/android/os/NetworkOnMainThreadException.html
NetworkOnMainThreadException is thrown if you attempt to make a network request in the main UI Thread. So all network related operation should be done on the background thread.
AsyncTask is designed to be a helper class around Thread and Handler and does not constitute a generic threading framework. AsyncTasks should ideally be used for short operations (a few seconds at the most.) If you need to keep threads running for long periods of time, it is highly recommended you use the various APIs provided by the java.util.concurrent pacakge such as Executor, ThreadPoolExecutor and FutureTask.
http://developer.android.com/reference/android/os/AsyncTask.html
class TheTask extends AsyncTask<Void,Void,Void>
{
protected void onPreExecute()
{ super.onPreExecute();
//display progressdialog.
}
protected void doInBackground(Void ...params)
{
//http request. do not update ui here
return null;
}
protected void onPostExecute(Void result)
{
super.onPostExecute(result);
//dismiss progressdialog.
//update ui
}
}
An alternative to asynctask is Robospice. Can make multiple spice request. Notifies on the ui thread. https://github.com/octo-online/robospice
To check Netowrk Connectivity.
In your activity
public class MainActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
if(CheckNetwork.isInternetAvailable(MainActivity.this))
{
//call asyntask and make http request.
}
}
CheckNetwork class
public class CheckNetwork {
private static final String TAG = CheckNetwork.class.getSimpleName();
public static boolean isInternetAvailable(Context context)
{
NetworkInfo info = (NetworkInfo) ((ConnectivityManager)
context.getSystemService(Context.CONNECTIVITY_SERVICE)).getActiveNetworkInfo();
if (info == null)
{
Log.d(TAG,"no internet connection");
return false;
}
else
{
if(info.isConnected())
{
Log.d(TAG," internet connection available...");
return true;
}
else
{
Log.d(TAG," internet connection");
return true;
}
}
}
}
In my android application the data has to be shared using twitter so had followed this link http://androidcodeexamples.blogspot.in/2011/12/how-to-integrate-twitter-in-android.html, everything works fine, but after giving username and password, getting force close option.
here's the logcat output
