  • Randomly generate sound from onClick and onShake events?

    - by Aaron
    I've literally looked everywhere on the net and found very little clarification on how to do this. Pretty much, I have 8 sound files laid out in an array.xml file and I need to play a randomly chosen file ONCE per or onClick or onShake. First off, what technique should I use to achieve this? ARRAY-RANDOM- STRING-PLAY? RANDOM INT-PLAY? RANDOM INT-STRING-PLAY? Any kind of direction will help greatly cause I'm almost 3 weeks worth of research into this. *NOTE: MediaPlayer mp = MediaPlayer.create(JelloMan.this, R.raw.sound) ...is what I'm stuck on being you can't replace the "R.raw" part with a string...

  • TimePickerDialog and AM or PM

    - by martinjd
    I have a TimePickerDialog with is24Hour set to false since I want to present the end-user with the more familiar 12 hour format. When the hour, minute and AM PM indicator are set and the time is returned how can I identify whether the end-user has selected AM or PM? This is what I have for the listener: private TimePickerDialog.OnTimeSetListener mTimeSetListener = new TimePickerDialog.OnTimeSetListener() { @Override public void onTimeSet(TimePicker view, int hourOfDay, int minute) { mHour = hourOfDay; mMinute = minute; // mIsAM = WHERE CAN I GET THIS VALUE } };

  • How to change internal buffer size of DataInputStream

    - by Gaks
    I'm using this kind of code for my TCP/IP connection: sock = new Socket(host, port); sock.setKeepAlive(true); din = new DataInputStream(sock.getInputStream()); dout = new DataOutputStream(sock.getOutputStream()); Then, in separate thread I'm checking din.available() bytes to see if there are some incoming packets to read. The problem is, that if a packet bigger than 2048 bytes arrives, the din.available() returns 2048 anyway. Just like there was a 2048 internal buffer. I can't read those 2048 bytes when I know it's not the full packet my application is waiting for. If I don't read it however - it'll all stuck at 2048 bytes and never receive more. Can I enlarge the buffer size of DataInputStream somehow? Socket receive buffer is 16384 as returned by sock.getReceiveBufferSize() so it's not the socket limiting me to 2048 bytes. If there is no way to increase the DataInputStream buffer size - I guess the only way is to declare my own buffer and read everything from DataInputStream to that buffer? Regards

  • Setting acquired location to a text view: How to maintain?

    - by Mark
    Hi, I have built an app for the Motorola Droid which should automatically update a server with the phone's location. After the user performs a particular task on the main activity screen, an alarm is set to update the user's location periodically, using a service. The alarm is explicitly stopped when the user completes another task. Thing is, I have set up a location manager within the main activity's onCreate() method which is supposed to place the first acquired lat/long into two textview fields. Even though the manifest is set up for acquiring coarse and fine coords and I'm using requestLocationUpdates (String provider, long minTime, float minDistance, LocationListener listener), with minTime and minDistance set to zero, I'm not seeing the coords coming up on the screen. With that, I'm not recording any locations on the server. When I seed the textviews with sample coords, they are being recorded fine on the server. I am not at a computer that can run the IDE, so don't currently have the code, but am desperate for some help on this. One other thing is that the main activity screen calls a photography app before the user manually clicks "send data". I'm suspicious that I may need to override the main activity's onResume() method to do this location acquisition. Please help, thanks. Mark.

  • Reading Images only from Camera

    - by Ankit
    I wanted to read images only from the Camera folder of the device. Since the folder might be different for different devices, how can I write a simple application for it). So far I have written the following code, which does read from Camera folder, but it also reads from other places on sdcard as well. Cursor childCursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, MediaStore.Images.ImageColumns._ID, null); do { ImageView image = new ImageView(); image.setImageURI(Uri.withAppendedPath(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, ""+ childCursor.getString( childCursor.getColumnIndex( MediaStore.Images.ImageColumns._ID ))); <some other code> } while (childCursor.moveToNext()); How can I create a generic app and filter on Camera Images before displaying. Any help is appreciated.

  • Convert InputStream to String with encoding given in stream data

    - by Quentin
    Hi, My input is a InputStream which contains an XML document. Encoding used in XML is unknown and it is defined in the first line of XML document. From this InputStream, I want to have all document in a String. To do this, I use a BufferedInputStream to mark the beginning of the file and start reading first line. I read this first line to get encoding and then I use an InputStreamReader to generate a String with the correct encoding. It seems that it is not the best way to achieve this goal because it produces an OutOfMemory error. Any idea, how to do it ? public static String streamToString(final InputStream is) { String result = null; if (is != null) { BufferedInputStream bis = new BufferedInputStream(is); bis.mark(Integer.MAX_VALUE); final StringBuilder stringBuilder = new StringBuilder(); try { // stream reader that handle encoding final InputStreamReader readerForEncoding = new InputStreamReader(bis, "UTF-8"); final BufferedReader bufferedReaderForEncoding = new BufferedReader(readerForEncoding); String encoding = extractEncodingFromStream(bufferedReaderForEncoding); if (encoding == null) { encoding = DEFAULT_ENCODING; } // stream reader that handle encoding bis.reset(); final InputStreamReader readerForContent = new InputStreamReader(bis, encoding); final BufferedReader bufferedReaderForContent = new BufferedReader(readerForContent); String line = bufferedReaderForContent.readLine(); while (line != null) { stringBuilder.append(line); line = bufferedReaderForContent.readLine(); } bufferedReaderForContent.close(); bufferedReaderForEncoding.close(); } catch (IOException e) { // reset string builder stringBuilder.delete(0, stringBuilder.length()); } result = stringBuilder.toString(); }else { result = null; } return result; } Regards, Quentin

  • Alarm not working if application gets killed

    - by Tobia Loschiavo
    Hi, I am trying to use an alarm to set my widget layout after some minutes. Everything works correctly in normal situation but, if I try to delete the process of my application, simulating a system kill, after the alarm is set, then no alarm is executed. Why? From documentation it seems that alarms are executed by AlarmManager service...so it should work. Thanks Tobia Loschiavo

  • What happens on Activity.finish() with AsyncTask still running in background?

    - by stormin986
    What happens on Activity.finish() with an AsyncTask still running in background? Does it just pop the Activity off the Activity Stack, but wait to destroy the Activity object until the AsyncTask fully completes (since the AsyncTask is an inner class of my Activity)? Also, would it act any differently if the AsyncTask were a public, non-inner class that held no references to the instance of the Activity?

  • JNI: Passing multiple parameters in the function signature for GetMethodID

    - by Jary
    I am trying to execute a function in Java (from C) that has the following signature: public void execute(int x, int y, int action); My problem is to define the function signature in GetMethodID: env->GetMethodID(hostClass, "execute", "(I;I;I;)V"); The problem I ma getting is: W/dalvikvm( 1849): Bogus method descriptor: (I;I;I;)V W/dalvikvm( 1849): Bogus method descriptor: (I;I;I;)V D/dalvikvm( 1849): GetMethodID: method not found: Lcom/device/client/HostConnection;.execute:(I;I;I;)V I am not sure how to specify the method signature in GetMethodID (for 3 integers as parameters). I saw people use the ";" to separate parameters in other posts for the String and File class, but nothing with primitives like integer. What would be the correct way to do this please? Thank you.

  • JAVA-how to manually compose a MIME multipart message

    - by Augusto Picciani
    I need to compose manually a MIME multipart message. I don't need to use any library to doing it. I'm trying this without success: out.println("From:myemail@mydomain"); out.flush(); out.println("To:myemail@mydomain"); out.flush(); out.println("Date:Thu, 25 Nov 2011 01:00:50 +0100"); out.flush(); out.println("Subject:manual test 269"); out.flush(); out.println("MIME-version:1.0"); out.flush(); out.print("Content-Type: multipart/mixed; boundary=\"1234567\"\n\n"); out.println("--1234567"); out.flush(); out.println("Content-Type: text/plain; charset:utf-8"); out.flush(); out.print("Content-Transfer-Encoding: 7bit\n\n"); out.flush(); out.print("test message\n\n"); out.flush(); out.println("--1234567"); out.flush(); out.println("Content-Type: text/html; charset:utf-8"); out.flush(); out.print("Content-Transfer-Encoding: 7bit\n\n"); out.flush(); out.print("<p><strong>test message in html</strong></p>\n\n"); out.flush(); out.println("--1234567--"); out.flush(); out.print("\r\n.\r\n"); out.flush(); Problem is that my mail client see the headers (from,subject,date,ecc.) but it doesn't see the message body. If i try without multipart it works fine. Maybe problem is in whitespaces character.

  • Application lifecycle. How to run something only when application starts

    - by David
    I have a dialog popup to indicate how long I want an activity to run. Seems simple enough, but its difficult to determine when the activity is really starting. If the user opens the keyboard on a G1 and thereby goes into landscape, that reruns the activities onCreate method. I can't have a static for the class or even create an application class, because I can't determine when the 'application' goes away. Even after destroying the only activity, the application is apparently still alive. Is there a way to determine that onCreate has been called because of the keyboard being extended or landscape mode invoked? Thanks
