Android :: Why The Duration Of Clip Is Different Between VideoView.getDuration And MediaMetadataRetriever.extractMetadata - MediaMetadataRetriever.METADATA_KEY_DURATION
Jul 17, 2009
When I create an APP for Media test, I'd like to get the duration of tested clip. Nut as the debug result, the duration is different between the 2 methods for many clips.
Method 1:
CODE:.....
Method 2:
CODE:.........
What is the reason? And I checked the result of Method 2 is right when compared with PC result. Is there a bug for MediaMetadataRetriever.extractMetadata (MediaMetadataRetriever.METADATA_KEY_DURATION)?

Some audio files return 0 from MediaPlayer.getDuration(), even though they're perfectly valid files that play ok and that players on Windows can find the duration of. There seem to be two different cases here: certain file types such as .wma and .wav always return 0 duration, and others only do so sometimes. I haven't been able to find any pattern in the latter case, but it does seem consistent per file. The music player displays 0:00 duration for these, so it's not just my code.

I am browsing the web but no way to find how to get metadata from a picture.
I can't see anything in the Bitmap/BitmapFactory/BitmapFactory.Options documentation that would give me a hint.
I would like to retrieve standard information such as:
name
date it was taken
dimension
size

I'm trying to get access to the metadata about podcasts, such as the show notes/description, the show title and the icon image. I'm at least partially using ContentResolver to query for most of the AudioColumns information, but for some reason ALBUM_ART is missing, there seems to be no column for the description, and in general, it's not clear what the mapping is. Since podcasts are not songs, they don't generally have "composers", "artists" and "albums" they have show titles, episode titles, hosts, etc. Is there any information out there on what standards are generally used for podcast metadata and how I can efficiently access it?

I want to store some metadata in images. My camera application gives me a bitmap, which I store in the storage (MediaStore) device. In addition to this, I want to add a few tags to the picture in its metadata. I think EXIF is a good way of doing this. But I couldn't find good references on how to do this.If there are some tools to achieve this task in Android programming,

In Visual Studio, I can obtain a succinct list of public methods/members exposed in a class for which I do not have the source (i.e. bundled inside a DLL) by pressing F12 (GoToDefinition).
Similarly, I am learning the Android API - in Eclipse. Jumping to an Android framework method definition produces decompilation output which is not intuitive to read, and is very verbose. To mimic results like Visual Studio, I am considering several options:
How can I format the decompilation output to be 'cleaner' - I have looked through Eclipse's preferences menus and have not found a way to do this.
How do I 'add corresponding source files' once Google provides it, so that jumping to definition yields the actual definition?
Is there a plugin that does this already? I looked into Jadclipse, but that project has not been updated in several years, and is still a decompiler.

Google Music stores it's my downloaded MP3 music on the internal phone memory on my Nexus4. I don't want to use any other player, I really like how Google Music gives me the best of both worlds, with regards to having my best stuff locally, and all music in the cloud.
However sometimes I want to copy a particular Mp3 from my phone to my computer. All the files are randomly numbered xxx.mp3, so I can't see which file is what track in MP3 explorer.
Any app that can browse a system directory (on a rooted phone), and show all the Mp3 metadata and allow copying of that file?

I received a Text message sent from an E-Mail and I was wondering if it was possible to find the individual file on the filesystem holding the metadata for the E-Mail.
If so, would I have to root the phone? And where would that file be located?
I'm a techie, so no need to warn me that I could hurt my phone or files - I'm only looking to READ, not WRITE, and I'd be making a copy of that file beforehand anyways and porting it to a PC in order to check it with whatever program is necessary to decrypt (Probably only need a hex editor.)

I need to display an alert message for no more than a half a second. As I understand it, Toast only has 2 available durations, with no way to alter them. Correct me if I'm wrong. Which leads me to sing the AlertDialog. What would be the best way of displaying a dialog for 500ms and then dismissing it?

I would get outgoing call duration a call, I thought to get when the persone to the other side answer my call, but with PhoneStateListener we can get the state of a call, but PhoneStateListener changes state to CALL_STATE_OFFHOOK immediately when the outgoing call starts and not when the person to other side answers, so i can't get the effective time of call during a conversation.

I'm using Android's android.graphics.Canvas class to draw a ring. My onDraw method clips the canvas to make a hole for the inner circle, and then draws the full outer circle over the hole:
clip = new Path();
clip.addRect(outerCircle, Path.Direction.CW);
clip.addOval(innerCircle, Path.Direction.CCW);
canvas.save();
canvas.clipPath(clip);
canvas.drawOval(outerCircle, lightGrey);
canvas.restore();
The result is a ring with a pretty, anti-aliased outer edge and a jagged, ugly inner edge:What can I do to antialias the inner edge?I don't want to cheat by drawing a grey circle in the middle because the dialog is slightly transparent. (This transparency isn't as subtle on on other backgrounds.)

Can anyone shed any light on why I'm unable to click and play a youtube clip on an Android handset when placed inside a webview?I've put a very simple app together (it's being extended, but no right away) and it has a web view assigned using the Android SDK.The rest of the webview works as expected (text, images, css etc), however, the YouTube clips will not show, they just show as black or white rectangles (where the video embed should be).We use the same view to display content on the iPhone app equivalent, without any issues.This is using a basic flash embed, the Safari browser on iPhone converts these to H.264 and plays them nicely in QuickTime.Can Android do the same?

We came across a strange behavior. The clip rect of our custom view is getting reset to its entire visible region, if we change the value of another view.

I'm writing an app for Android OS, and I need to store some time values in the SQLite DB. I have been using android.text.format.Time to store the time values in the app, and then inserting the values as millis into the DB as REAL values. On the SDK emulator, everything works perfectly. On the sole phone I've had the opportunity to test my app (so far), my duration code doesn't work as expected. Some relevant code:
private static final String DATABASE_CREATE =
"create table " + DATABASE_TABLE + " ("
+ KEY_ROWID + " integer primary key autoincrement, "
+ KEY_START + " REAL, "
+ KEY_STOP + " REAL, "
+ KEY_DUR + " REAL );";
private SQLiteDatabase mDb;
ContentValues timerValues = new ContentValues();
timerValues.put(KEY_START, stime.toMillis(false));
timerValues.put(KEY_STOP, etime.toMillis(false));
timerValues.put(KEY_DURATION, stime.toMillis(false)-etime.toMillis(false));
int result = mDb.insert(DATABASE_TABLE, null, timerValues);
I pull this data from two separate functions with slightly different bits of code, both using Time.set(long millis), both giving incorrect results: The start and stop values come back correct, but the duration comes out 17 hours too large. Am I missing something about calculating durations or does this just seem like there's something "special" about this particular droid? I'll have another droid to test on Monday, but any ideas are appreciated.

Is it possible to modify an active call by overlaying a sound track during the call? I looked up the SDK, but couldn't find any api to do this in the documentation. I am trying to investigate the feasibility of playing a previously recorded call/audio clip onto an ongoing call.

I've used the voice recognition feature on Android and I love it. It's one of my customers' most praised features. However, the format is somewhat restrictive. You have to call the recognizer intent, have it send the recording for transcription to google, and wait for the text back. Some of my ideas would require recording the audio within my app and then sending the clip to google for transcription. Is there any way I can send an audio clip to be processed with speech to text?

I am having the following problem: I am using Android's MediaPlayer to play an mp3 through an HTTP connection. The audio is played correctly, but the MediaPlayer returns an incorrect duration (calling mediaPlayer.getDuration() ). Depending on the mp3 the duration is either shorter or longer. The code that plays the audio is the following:
mediaPlayer = new MediaPlayer(); mediaPlayer.setOnCompletionListener(this); mediaPlayer.setOnErrorListener(this); mediaPlayer.setOnPreparedListener(this); mediaPlayer.setOnBufferingUpdateListener(this); mediaPlayer.setDataSource("a valid URL"); mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC); mediaPlayer.prepareAsync();............................

I'm using the SoundPool to play a series of small audio clips and am having issues with the audio when it starts. I have the audio attached to a button press. When I press the button mulitple times the tick persists. I was wondering if this was the audio file itself or is there something I need to do differently with the SoundPool other than play simply play the clip. These are .ogg files I created using Audacity. When I play them in my dekstop media player, they sound fine.

I need someone to test my First app I did. It is reworked and extended version of Android DatePicker app here: Date Picker | Android Developers. I don't have Android creature, because I am out of the Google test area. My app shows Time Duration using the DatePicker Dialog twice
The result can be seen on the image.
Please email me and I'll attach the tDurator.apk for you. I need feedback about the working state of the app when rotating the Nexus 1 device, but anyone having at least Android system 1.5 (level 3 on the SDK) can run the app. The app is signed for release and in not harm to the phone.
