[android-developers] Re: MediaPlayer HTTP streaming buffering: any settings?
OK, I found a kind of way out; not perfect though. I create two MediaPlayer instances (primary and secondary); I also create three files. I have a thread which reads HTTP stream and buffers N seconds to first file. Second file goes to secondary player's prepare method. Third file is played by primary player. After playback is finished, both players and buffers are rotated. This works almost well, but: - there's an audible gap when switching players. - I'd switch from files to memory buffers/streams, but I have no idea how to make MediaPlayer play from Stream directly :( I have streams of 16-32kbps and buffers of 5-10 seconds so memory is not an issue at all. -- You received this message because you are subscribed to the Google Groups Android Developers group.

least everything is compiling, and the emulator started up.
Should dx.jar be with the SDK?

I end up with a flow layout, which may work for many things, but it makes for a sucky on screen input. I'd appreciate any ideas. Here are the specs that I want to aim for: 1) I want to be able to place the keys exactly where I want them 2) I want them to register on finger down, I'll explain below* 3) I'm considering key registering by collision like a video game rather than by button, but that is probably too complicated for a first time out, so I'll just stick with the other two for now. * On many on screen input methods, if not most, the key registers on finger up. The problem with this is if I hit G and then hit an O before letting go of the G, most devices will give me the G but not the O, and some will even give me a J instead, as a compromise of the two locations. I know this problem isn't unique to android because it happens on a few iOS apps as well. So, what I'd like to do is register a finger down event, and have that trigger a routine that sticks things in a buffer, to be released as text out on a finger up, but I digress I really have to tackle the layout issue, so, starting with, absolute layout, or what would be really nice is layout as % of total screen so each key could be 10% of the screen width for qwerty, and then again for asdfg, only with a left margin of 2.5% and a right one of 7.5% (or a key there, like enter, or the elusive apostrophe.) Also, I'm thinking that I want to possibly be able to resize this keyboard for tablets, (this is mostly a tablet app, you can't really finger type on a phone.) If I resize it, then it just has to be some % of an abstract size that the app creates, and then that can be translated to the user's screen size. Anyway, sorry this post was longer than intended.

[android-developers] Why doesn't the ADT show me the javadoc for a class in android.jar when I have the javadoc path set for the jar?
This may be completely Eclipse-specific, but perhaps not. I find it's very inconsistent whether I can get Eclipse to show me the Javadoc for an Android class or method, even when I appear to have valid javadoc attached to the android.jar file. For instance, right now I'm viewing a class in a sample application that references SQLiteDatabase. There are no compile errors, so I have all of my dependencies properly set. I hover on the class name reference and force the javadoc to display, it prints the class name as android.database.sqlite.SQLiteDatabase, but it says Note: This element has no attached source and the Javadoc could not be found in the attached Javadoc.. I then went into the Project Explorer and expanded the Android 2.3.3 library, exposing the android.jar file. I right-clicked on that and selected Properties. I clicked on Javadoc Location. It's currently set to Javadoc URL and the Javadoc location path was set to the path to the reference directory in the android SDK. I clicked Validate and it said Location is likely valid. Just in case, I verified that android/database/sqlite/SQLiteDatabase.html exists at the root of the javadoc tree. So why is it not showing the javadoc for this class? -- You received this message because you are subscribed to the Google Groups Android Developers group.

giving Null pointer exception. please check the code.
btnEncFile = (Button)findViewById(R.id.btnEncFile);
// at this line btnEncFile value is coming Null, i checked it using
breakpoints so it is giving NullPointerException
btnEncFile.setOnClickListener(new View.OnClickListener()
{

I am writing a code for simple navigation between different pages in
android application. I created a Button and then on Click event i am
setting my ContentView. i have written same code for 2 buttons working
fine. but when i am writing click event for 3rd button and it
navigates to a page named encrpyt_file.xml. its not working. its
giving Null pointer exception. please check the code.
btnEncFile = (Button)findViewById(R.id.btnEncFile);
// at this line btnEncFile value is coming Null, i checked it using
breakpoints so it is giving NullPointerException
btnEncFile.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
setContentView(R.layout.encrypt_file);
}
});
why this exception is coming, i have written the this code many times
in my applications but this time i can't understand why its giving
null pointer.
please suggest me something if i am missing out something?
2- encrypt_file.xml
?xml version=1.0 encoding=utf-8?
AbsoluteLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:layout_width=match_parent
android:layout_height=match_parent
