I have a button that plays an audio file on its click listener. If the button is clicked again and again while the audio file is being played then the app crashes. What's the solution?
Here is some code for reference...

Does anyone know of a player that will handle MP4 AVC files with a 5.1 AAC audio stream? The video plays just fine but none of the players seem capable of "downmixing" to stereo.
I did find one that would play the sound all garbled. I'd hate to have to recode my entire library to stereo to use it on my phone.
I think I should know this, but my mind has gone blank. I'm making an app that has a few hundred small sound files and I want it to play a certain file dependent on a String I pass to the function. Where I hit the brick wall is getting the resId of the sound file.

View 1 Replies View RelatedHey, I have a problem with android programing when I try to record and then play the file that was just recored. I can both record and play the sound but the quality stinks. Its not just bad is really hard to listen to and sound abit like its a computer generated voice. I use the andriod SDK-emulator. The code that sets up the recording looks like this;
MediaRecorder recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.RAW_AMR);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(path);
recorder.prepare();
recorder.start();
And the code playing the file later looks like this;
MediaPlayer mp = new MediaPlayer(); mp.reset();
mp.setDataSource(path); mp.prepare(); mp.start();
I don't know what part that makes the audio file sound really bad or if its just the emulator that makes it bad and that it would work on a real phone.
Ok so I see a lot of people saying they are having problems with video playback when importing from their SD Card but Im having the opposite problem.
I just switched over from the Metro PCS Samsung Code which is a Windows 6 phone to EVO and I put my SD Card in my EVO. All my music files play and the mp4 video files play but the audio from the mp4 video files dont. Does anyone have advice on how to fix this?

I have class A in which I have a method openfileConnec().
It was written like the below:
CODE:...............
Now I come to class B where I will call this method like the below:
CODE:.............
I was asked a question in an interview as follows:
Why does the method have a throws Exception in its declaration? Is it that on of the methods called in the implementation throws the base class exception? Also If we get a exception during calling the method (fileConnect( )) control goes to catch block. After executing catch where should the control go, what should be sent to base case?
I am creating an Android app that includes a third party jar. That third party jar utilizes internal logging that is failing to initialize when I run the app, with this error: "org.apache.commons.logging.LogConfigurationException: No suitable Log implementation".
The 3rd party jar appears to be using org.apache.commons.logging and to depend on log4j, specifically log4j-1.2.14.jar. I have packaged the log4j jar into the Android app. The third party jar was packaged with a log4j.xml configuration file, which I have tried packaging into the app as an XML resource (and also as a raw resource).
The "No suitable Log implementation" error message is not very descriptive, and I have no immediate familiarity with Java logging. So I am looking for likely causes of the problem (what class or configuration resources might I be missing?) or for some debugging technique that will result in a different error message that is more explicit about the problem. I do not have access to source code for the 3rd party jar.
Here is the exception stack trace. When I run the app, I get the following exception as soon as one of the third party jar classes attempts to initialize its internal logging. code...

Is there a way to determine the audio format of an audio file in Android? On normal java I do it like this:
File file= new File(...);
AudioInputStream stream = AudioSystem.getAudioInputStream(file);
AudioFormat format= stream.getFormat();
I would like my users to develop their own routines for image manipulation. Lets presume that a third party has written a class which implements one of my interfaces; public abstract class PixelBinaryFilter extends BinaryFilter{protected abstract int generatePixel(int p1, int p2);}

I really want to know why I can not hear any sound whatsoever simply because the video uses 5.1ch aac instead of 2ch aac. The video part of mp4 plays perfectly, encoded to h.264. I would really like to know if there is any media player able to play these videos correctly without having to resort to any kind of re-encoding (a waste of time when the original encodes should play fine) or having to use special 5.1ch headphones (bulky and not practical to keep on hand all the time). Also, does anyone know if this might be corrected with Froyo 2.2? And last, all my videos that have 2ch audio play as they should, sound and all. Same codec settings were used.

View 1 Replies View RelatedI am using a MediaPlayer instance in order to stream audio files from an Internet location. The audio player is in a separate activity. The user can select from a list of audio files and come to this activity which plays the audio.Now the user might go back to the previous activity (with the list)and select another audio file. In this case, I want to stop any other audio that is playing and start playing the new audio which was selected.Is there any way I can know whether an audio file is playing without having to hold on to the MediaPlayer object?

I'm using the Android Development Toolkit (ADT) in Eclipse Galileo. I've created a project in which to develop some util classes, which I intend to use in several upcoming Android projects. However, when I come to use these util classes (deployed as a jar and included in the Android project as a user library), I get a java.lang.VerifyError during the startup of the emulator. Can I force the verification of these library files, or do I need to include them as part of the Android project, and not as an external jar?

View 2 Replies View RelatedI'm trying to very quickly port over an html application with plays sound (with soundmanager2) to a native android app using WebView. From my research, I haven't seen any evidence that sound, such as mp3s, can be played via javascript or any other methods using WebView.
My goal now is to quickly port over the html app and then eventually create a truely native application without using WebViews.
If anyone has been able to successfully implement playing audio using WebViews and Javascript or if this is just not possible at this time.
I want to accept incoming calls and play an audio file for the caller. Is there a possibility of playing an audio file during a phonecall, so that the caller hears a wav- file? It seems to me that nothing is possible during a phone call since release 1.0. Hope this is getting better in the next release.
View 5 Replies View RelatedMy self-teaching project is a small application which plays an audio news stream. To be effective, the application really needs to interrupt any currently playing media players (eg: Last FM, Imeem, music player, Spotify etc).I don't know what will be playing or what application will be playing it, but I want to ask them all to pause until I've done. Sounds rather bold, I know, but it must be possible, because when there's an incoming call, that's basically what happens.Can I send a message to all audio players asking them to pause for a moment? Could I spoof an incoming call, just for the time it takes?
