Android ::PCM Output Code From Java To Android AudioTrack API

Apr 25, 2010

I'm attempting to port an application that plays chiptunes (NSF, SPC, etc) music files from Java SE to Android. The Android API seems to lack the javax multimedia classes that this application uses to output raw PCM audio. The closest analog I've found in the API is AudioTrack and so I've been wrestling with that. However, when I try to run one of my sample music files through my port-in-progress, all I get back is static. My suspicion is that it's the AudioTrack I've setup which is at fault. I've tried various different constructors but it all just outputs static in the end. The DataLine setup in the original code is something like I've replaced constants and variables in those so they make sense as concisely as possible, but my basic question is if there are any obvious problems in the assumptions I made when going from one format to the other.

Android :: AudioTrack Stop/release - AudioTrack Plays In The STREAM Mode

Dec 25, 2009

I need to stop the AudioTrack, regardless what's in the buffer, immediately when executing the stop/release. The AudioTrack plays in the STREAM mode. It appears that the AudioTrack finishes playing what's in the buffer and than stops. It seems that it's such a fundamental flaw since there are so many audio applications out there.

Android :: CTS Fails For Java Output Stream Writer Test

Aug 24, 2009

Please give me a clue, to pass CTS. I'm try to do CTS test. The Android 1.5 r3 which I get from Android Open Source fails CTS. Mean while, if I download Android 1.5 r3 and run CTS test for emulator it's PASS. the module fail CTS is: java.io.OutputStreamWriterTest I run test with follow string: start --plan Java -t tests.api.java.io.OutputStreamWriterTest#test_write$C I found that java.io.OutputStreamWriterTest class belongs to core.jar I compared sizes of core.jar build by me and build by Google, and it's different for 362 bytes. I'm completely frustrated. What's I'm doing wrong! For building we use: Java jdk: 1.5.0_16 Ubuntu version: 8.04 All others libs installed as mentioned on the http://source.android.com/download.

Android :: Java + HTML To TXT Library That Mimics The Output Of Lynx -dump?

Nov 12, 2010

I need a library in java that can take HTML content and generate text in the same format that is generated by the Linux lynx program.

That's it. Reasons below if you care.

I need to expose data provided by 3rd party servers to end users on Android. Data format is ancient, in badly formatted HTML, so much that I've tried reading it using java and it fails occasionally (unacceptable). It is also growing every month (preinstall ruled out) and I can't convince them to change to "modern" stuff (life would be great in XML etc.).

Shortest route: I wrote a class to use the W3 html2txt service online (google search it). It worked fine on the app until I got complains and noticed that the W3 service fails occasionally. It's not that big of a deal, but the black box logic expects the output to be in this "lynx like" text format.

So I would like a library to do the conversion (HTML->TXT) in "lynx style" inside the app and avoid the outages in the W3 service. And besides, the lynx output the probably the best I've seen, the most organized and neat.

Android :: Using Generics In Java Code

Sep 28, 2010

I need to de-serialise a file into an object of a given type. Basically the method will do this:

FileInputStream fis = new FileInputStream(filename);
ObjectInputStream in = new ObjectInputStream(fis);
MyClass newObject = (MyClass)in.readObject();
in.close();
return newObject;


I would like this method to be generic, therefore I can tell it what type I want to in.readObject() to cast its output into, and return it. Hope this makes sense...then again, I probably didn't understand generics properly and this is not actually possible, or advisable.

Android :: Get Reference To TabWidget In Java Code

Mar 9, 2009

In my layout xml, I have: <TabHost android:id="@+id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent">

<TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content"/>

</TabHost>

My question is how can I get a reference to TabWidget object. I tried this: mTabWidget = (TabWidget) findViewById(com.android.internal.R.id.tabs); but this won't compile since 'com.android.internal.R is not visible. And then I try change the id to android:id="@+id/tabs" but I get a run time error saying: "Your TabHost must have a TabWidget whose id attribute is 'android.R.id.tabs'"

Android :: Correct Way To Specify Dimensions In DIP From Java Code?

Nov 24, 2010

I found that it is possible to set dimensions of my interface elements in XML layouts using DIPs as in following fragment : "android:layout_width="10dip" But all Java interface takes integer as arguments and there is no way to specify dimensions in DIPs. What is the correct way to calculate this? I figured that I have to use property density of DisplayMetrics class but is this a correct way ? May I rely on that formula:
pixels * DisplayMetrics.density = dip

Android :: Eclipse Reading Code As Java

Nov 23, 2010

Pretty much everything is under lined and I can't seem to find a way to change how it is interpreted. I have downloaded all of the Android SDK's and the Eclipse Plugin. I can create Android projects and write the code just fine, but everything is still underlining. I must be missing something simple. Any suggestions, something I missed or didn't download?

Android :: Java Code Formatter Profile For Eclipse IDE

Mar 19, 2010

Did anyone create the Java Code Formatter Profile for Eclipse IDE that conforms to the Android Code Style Rules? Android Code Style Guide defines "Android Code Style Rules".To conform to these rules one have to change quite a number of settings of the Java Code Formatter
(Window->Preferences->Java->Code Style->Formatter) default profile (in Eclipse IDE).

Did anyone manage to configure the formatter to follow the "Android Code Style Rules" already?
If yes, please export the Formatter profile and publish to be used by community. I've tried to do this myself but I've found that there are too many formatter options available, and most of them are not mentioned in the Code Style Guide.
