If it compiles from source with JDK 5 or JDK 6, it should work without issue on Android when that code is cross-compiled into Dalvik VM bytecodes by the rest of the build chain. Hence, the only warnings you will typically see come from the JDK javac compiler. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Android Training in US: 14-18 June 2010: http://bignerdranch.com -- You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Re: Passing Command line arguments
The "am" command in the shell starts applications. Use "adb shell" to get a shell. Then type "am" without arguments and you will see the parameters for this command. Command line arguments to Android applications are equivalent to what is passed in an Intent object. Since you use the "am" command, you do not actually invoke the application directly. You specify arguments that match an application's intent filters. So "am" is useful in cases where you want to try different Intent objects and matches without modifying code. There is no difference or advantage to launching an app from the command line. -- You received this message because you are subscribed to the Google Groups "Android Beginners" group. NEW!

[android-beginners] Re: PCM format
Hi Chris 16bit PCM is signed. Its data type is in shorts. (not floating point). A WAV file is little endian byte order. That means if you read it with a java method you have to reverse the byte order using a ByteBuffer() since java reads things big endian. (Read the data, move it to a byte buffer that has the correct order, and get the array of data from that buffer). Reading the WAV in native code using the NDK is faster since it will read in little endian to start with. amplitude of zero is simply the value zero. For stereo data, the sound is simply "interleaved" like so: leftrightleftrightleftright. So you have short data, and left is first, then right, then left, etc. on left/right combo is a sample. Google WAV file format. The same format that the PCM data in a WAV is in is the same format the AudioTrack expects. -niko On Mar 23, 9:18 pm, MadVillain wrote: > Hey I'm just beginning writing Android apps and have a basic, but poor > understanding of digital audio.
