Android :: MediaPlayer - Failure In Wav And 3gp Formate
Jul 8, 2009
I was very confused for MediaPlayer, follow the audio supporting formate from: http://developer.android.com/guide/appendix/media-formats.html
I success in mp3 formate, but failure in wav and 3gp formate.. i can't figure out why i can't? the other question is the error message from adb logcat,
E/MediaPlayer( 729): error (1, -1) E/MediaPlayer( 729): Error (1,-1)
What's the "(1,-1)" means? i try my best for several methods and audio/video support formate, but still failuere, and always get the error message..

I have a requirement to play several sounds many times in my game so instead of creating the MediaPlayer again and again I have called mp.seekTo(0) in onCompletion(mp) so that it will restart. Sometimes the sound is not audible from the device when I call mp.start () after setting mp.seekTo(0); but the player calls onCompletion() without playing any sound, this is observed randomly on most of the sounds
My sounds are of short duration mostly less than a second.
I am using a separate MediaPlayer for each sound (as I need this) -
There are almost 28 sounds in my game so i will be creating 28 MediaPlayers.
Below is the attached code for player
Also If I try to play many sounds one after the other in a short period of time i get an error saying "no more track names available". can u tell Why this is happening...?
check the below code:

If one downloads the Linux SDK (1.6) the extension of it is .zip but in fact it uses the .tgz format. So if anyone cannot unpack just rename the file to .tgz and it will work. I am surprised that no one from Goolge tested that and that no one complained so far.

I am connecting to a server on my network written in C#. The data sent from the android device is received by the server and a reply is succesfully sent but the android code timesout and never gets the return data.I have tested that the C# server can communicate and reply with a C# client.
I have studied the network traffic using Wireshark when using both the C# server-android client and C# server-C# client and it appears that the android device acknowledges(ACK) the reply data but my code never recieves it.
I have the code running in a thread so running it on Android 4.0 doesn't error out but I have tried running it on Android 2.2 with exactly the same behaviour(or lack of it). Also I have run it on 2 different android devices.
(AndroidManifest.xml)
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
(My Code)
[code]...

I have downloaded the Layar401.apk file from web and trying to install it into my android device [HTC Magic, OS 2.2]. But every time I'm trying to install it its saying -
adb install Layar401.apk
1098 KB/s (1855698 bytes in 1.649s)
pkg: /data/local/tmp/Layar401.apk
Failure [INSTALL_FAILED_MISSING_SHARED_LIBRARY]
From other posts I figured out that there might be a missing shared library of google maps api in manifest.xml file. I tried to view the manifest.xml file and it gave me something like following -
package: name='com.layar' versionCode='27' versionName='4.0.1'
uses-permission:'android.permission.ACCESS_NETWORK_STATE'
uses-permission:'android.permission.INTERNET'

densities: '120' '160' '240'
But here it says library includes google maps api as well. So I'm not sure why I'm not able to install this apk file.

I followed instructions from here. After $ repo sync I tried to build it with $ make, but got this error:
CODE:............
Using Ubuntu 10.04 LTS.
UPD: I found a discussion, that claims, that problem could be that I'm having 64bit libs on my 32bit system.
CODE:.....
How do I figure out, if that libz.so.1.2.3.3 is the right lib, and in case I have to replace it with the right one, how do I do it?

I have a similar problem to this question, but slightly different. I have compiled a .so library to use with JNI. Because it is large (15 MB), I am putting it on the SDCard instead of in the standard application place.
The file is called libSample.so and it's located at /data/library/libSample.so
I load it in a static initialization block:
CODE:.............
Here's the relevant logcat output:
CODE:............
I read the post about can android load dll's from sdcard in native mode which said that the sdcard cannot be used to load libraries, so I moved the .so into /data/data/com.example.hellojni/lib/libSample.so (the private app data storage location). No change:
CODE:.............................
What I don't understand is that clearly the library exists, and the OS is trying to load it ... so what would make it fail?
Following the advice of one of the commentors, I tried attaching via strace to get more detailed error information. The log can be found as a github gist.
The error appears to be on lines 47-51:
CODE:...........................
Here's the readelf of the library:

Does the API restrict you from attaching to another database while you have one open?I tried the SQLite3 command "attach database .../contacts.db as aliasdb" .This works in the adb shell and I'm able to perform joins with tables in this database. When I use the same command via the API using "db.execSQL(attach database/contacts.db as aliasdb)" it gives me failure 14.Is this restricted on purpose or am I making a mistake somewhere?

I created a simple client socket from my Activity, but it fails. I am running this activity in emulator and server runs on PC(its a different application without Android stuff).
*clientSock = new Socket("127.0.0.1", 30001);*
logcat shows java.net.SocketException: permission denied <maybe missing INTERNET permission>
If I enable permission for my Activity(android.permission.INTERNET), my Activity constructor itself not called and logcat shows following info. Permission Denial: starting Intent < flg=0x10000000 cmp=com.example.client/.MyClientActivity > from null <pid=-1, uid=-1> requires android.permission.INTERNET.
Any suggestion on how to resolve this issue?

I am working on an app that uses a Socket to connect to a controller over TCP. The protocol library was written in Java and I am implementing it in android via a Service. where the Connection class is a Thread that handles the communications with the controller. It's where the Socket lives.I'm using the Preferences mechanism to store the IP and Port. If I feed the Socket the correct IP and Port, the Connection Service works beautifully. However, I am trying to simulate a user entering the wrong information and having the connection fail. The ultimate goal is to present a dialog and offer the ability to "reconnect" or "update settings". However, when I enter a wrong Port number, the application simply hangs.I was under the impression that Threads executed concurrently so I've tried moving the call to start the Connection Service to a Thread, but it still hangs the application.

I'm trying to write a basic camera app. The problem that I am facing is that it works fine in emulator but on the phone (Nexus one) it fails.
The point of failure is the very first call, i.e. Camera.open(). It fails on the phone saying "Failed to connect to camera service". Any idea what could be wrong? (BTW, I am calling this from my activity's onCreate funtion itself, could that be an issue?)
For the information, I do have the necessary Camera permissions specified in my manifest xml file.

Hey folks HumanMachine here with a little query for those of you who were lucky enough to have picked up a 32GB MicroSD for your phones.I had, and lost mine, in the course of two days. Short story incoming. TLDR Below I was using my phone at work and decided to change my Live Wallpaper, I'd downloaded a few of them and was going through them just to see how they looked in motion. I remember specifically looking at the "Starfield" wallpaper. I then selected the "Battery - Couple the ship's energy source with phone's battery" To see what the option did. I backed out to apply the Wallpaper. And the Droid X locks. Weird I thought, maybe she's just lagged.Turned out a lot worse than that. She was just straight up frozen. Stuck on this unusable frozen starfield. I couldn't quite remember how to reboot the phone. or even if it were possible, Couldn't power her down, so I removed her battery, figured that would be enough to get her back to life.I was met with a message, once the phone loaded up. "SD Card blank or has unsupported filesystem" Not the first time I've seen this issue pop up on the android forums. I immediately popped the MicroSD card into my little USB dongle and attempted to access the MicroSD. Shows up in "My Computer" just fine. but when I tried to access it? "Please insert disc" et cetera et cetera.
I try to format. No dice, Computer won't even find the thing. Try my SD formatter, no dice.Stick the 16 GB card back into the phone, and we're sailing again. And here I am staring sadly at the card.I tried for about an hour more to breathe some life into it. I just couldn't get the computer or phone to read the card. Same error messages.TLDR For those of you who wanted to skip the story SD Card died. pathetically, didn't lose much but still. My question, do we have any idea what the failure rates are on these bad boys? I didn't mistreat or even do much with mine before this issue came up. Hopefully I just had a lemon. Unfortunately, the store I got mine at. Verizon store actually, didn't have any, nor do they know when they will get a shipment of them.I'm bummed. go figure. Time to play the waiting game.

I just installed android sdk1.5 on a ubuntu 8.04 machine. The IDE is eclipse3.4 with ADT. I created a HelloAndroid project with only the automatically generated code. It compiled successfully and worked on the emulator. But when I tried to install the apk to my G1. It failed with only return code [-12]. I tried anroid 1.1 and android 1.5. The results are the same. But my G1 works fine when the sdk is 1.1. Any idea?

In 1.6 I do the following to stream an mp3 shoutcast stream:
CODE:...........
This works great. However, I have to support phones running 1.5 as well. When I build against the 1.5 libraries and run in a level 3 emulator, I get an exception on the prepare() call with the message: Prepare failed.: status=0x1.
Is this supported in 1.5. Is there some other mechanism I have to use that will work in both?

I have such code:..............
When my sound played for the first time, it's all fine. But when for second, third, etc.. it sounds like cutted, just little part of my "click.wav". If I put there sound in another format like mp3 or ogg - all just fine.
Or if I write like this: mp_click = MediaPlayer.create(CubeTest_Main.Context, R.raw.click); mp_click.start(); All if fine too, but this is a bit slow, becouse this sound is playing very often.

I am developing a media player application which downloads from internet and plays. so while downloading I want to show a progress bar saying "buffering...", and while playing I want to dismiss the same progress bar.
