Android :: SetParameter In AudioManager.java
Mar 10, 2009
We are planning on using setParameter() function in AudioManager.java for turning on/off some audio effects from the UI. This function goes all the way to the HAL layer. However, we see a comment in the code saying the following (pasted at the end of mail). So, my question is it okay to start using this API with our own defined set of (key,value) or is there a possibility of this function disappearing later. If yes, then is there any other recommended function to pass on UI settings all the way down to the HAL.

I'm having a bit of trouble with an Android app that I'm working on (mostly for practice and learning purposes) that uses the AudioManager object.
When defining the AudioManager as follows, however, the app crashes when I run it:
CODE:................
When I simply comment out the AudioManager declaration, the app does not crash. Any ideas as far as what I'm doing wrong? I'm a bit of a beginner to Android development, so I have a feeling that I'm missing something obvious.
I've also tried adding the android.permission.MODIFY_AUDIO_SETTINGS and android.permission.MODIFY_PHONE_STATE permissions to the AndroidManifest.xml file, but that has made no difference.

We just released our first widget to the market called AudioManager, it's available now and free to download to anyone who has cupcake already installed.AudioManager is a home-screen Widget that allows you to get live readings of your current volume levels on your Android phone (similar to your computer's "Volume Mixer").Tap on the screen and you can adjust the volume levels individually for the following streams: Alarm, music, notifications, ringer, system and voice call volume.The widget comes in two sizes, large (4x1) and small (2x1). The AudioManager Console is also available through your application launchpad in case you do not need the Widget on your screen but wish to access all volume streams from one place.Attached are a few screenshots, check it out and let us know. Only tested with Android's default home-screen, however, there are mixed reports of the widget working for aHome and dxTop with the latest versions.

I can't seem to change alerts and ringer volume seperately using Audiomanager pro. Whilst at work i want to hear my txt message sounds (alerts) but not my ringtone, and i want the phone to vibrate with both still. However when moving the ringtone and/or alert slider the other one moves too, they can't seem to move seperately. Am i doing something wrong or does this app not do that, and if so, is there an ap that does?

Just wondering, on 1.5, the Ringer/Alerts volume was locked together so however loud the Ringer volume was, the notification volume would be the same. Since upgrading to 2.1 OTA, they are no longer linked together. Is there any way I can link them back together so they are they same volume without having to individually change each one? It's kind of annoying when I set my Ringer volume to low, and all of the sudden I get a text and it's almost 3 times as loud.

I'm having some problems porting a Java application to work in Android platform. I detected an incompatibility problem between java sun and Adroid sdk in java.lang.Class. I oberved that: public Field[] getFields() Returns an array containing Field objects describing all fields which are defined. That's array is sorted as attributes are declared in the main Class in sun jdk. For example, next Class is defined as: public class Example { public boolean stop; public int atr1; public String name; ....

I do an import of the full package name / java file, and if I do a <classname>.<method>, SOMETIMES I can get it to access - other times I get a lot of can't use a static in a non static bunch of talk. I'll admit I'm new to Java, so what do I need to do? Call a class instance first, then call my methods? I'm rather confused by this, as I want to put all of my 'functions' into a FunctionsList.java file, and all of my main Activity (UI) into a MyActivity.java file.
For example:
<MyActivity.java>
import com.example.FunctionsList;
private class MyActivity extends Activity {
FunctionsList.function();
}
9/10 times I get that static/non-static error. If I put all of my functions into MyActivity.java, I have zero problems!

I was going through the code for Activity.java and ApplicationContext.
Both these classes define many functions of Context Interface. Take for example startActivity.java
Activity Class has its own implementation of startActivity ApplicationContext class also has an implemenetaion of startActivity.
Now there are 2 observations...
CODE:..........
Questions: 1. Who uses ApplicationContext class? 2. Does Activity class ever deal with ApplicationContext class (as given in the javadoc comments of ApplicationContext.java).

I know there are plenty of tutorials about integrating C++ into Java, but whats about the other way around, a Bridge from Java to C++?
The reason i'm asking this is Android.
Every C++ developer who wanted to write applications for the android noticed at some point that there is no serious (mature) C++ api for android (infact, android is lacking an implementation of the STL).
The only API that is mature enough to write android applications in, is Java. So instead of writing an api from scratch, wouldn't it be possible to use the Java Classes from C++?
I know that this sounds merely like an unrealistic dream, but that way most C++ developers weren't forced to learn a new Language.

I've seen this question asked many times but none of the answers really made sense in what I'm doing... I have an android game (see source at Google source control: http://code.google.com/p/bestcardgameever-android/source/browse/#svn/...) It's a card game, and I've used a method that redraws each hand every round - that might be wasteful but I couldn't think of a better way to do it. Code...

I can debug the Android Java code using eclipse and using the Remote Java Application debug configuration. This does not step into C/C++ code however as expected. I understand I have to attach the gdbserver to do this. Can someone provide a step by step tutorial on how to debug the native code of Android?Is there a eclipse plugin that makes this easier?

How can I add a layout to another layout in java? In xml, you can do it with include. How can you do it in Java without the help of XML? (I need to know this because the number if includes changes dynamically).

The API I need to work with does not support xpath, which is a bit of a headache! The xml I want to parse is as a String. My questions: Is there a Java equivalent of "simplexml_load_string", where it makes the string into an xml document for parsing? Which is better for parsing, SAX or DOM? I need to get a couple of values out of the XML and the structure isn't that deep. [3 levels]

We are implementing a sever-client architecture and some of the client apps are supposed to run on android OS. The first idea that came to mind was to use Java RMI, but the RMI api is obviously not implemented for android.So
1) Is there a way to use the Java RMI api in an android application? Can I just import it from the standard java library?
2) What are the possible substitutes for RMI which will work for both android and desktop applications?

I am learning Android development, specifically to eventually do OpengL 2.0 ES on it. So far I have read that the NDK supports Opengl 2.0 ES. However, is there also a Java API for it? If there is a Java API for it, which one is recommended? I know both C++ and Java, so it is not a big deal if I have to use the NDK, but I would prefer to work only in Java if possible and without a big performance hit.

I've been working on a project for several weeks now, and just tonight I started having a problem. The R.java file is no longer being generated. I've attempted to clean the project (the first time I do this it removes the R.java file but doesn't regenerate it) and have tried uninstalling and reinstalling the SDK. I've also tried resetting adb to no avail.
This problem does not occur in my other Android projects. They clean just fine and regenerate the R.java file like nothing is wrong. This particular project is the only one suffering from this problem.

I am about to start developing an Android application and had a question if in Java there self naming. For instance say I had a variable named dog that held the value of scruffy. Could I then create a variable named scruffy from that variable. In PHP it would be $$dog. That would make a variable with the name scruffy.

So I have the basics down... I can create a UI with the XML, I can show it and change the screen to another UI (another XML file) but how do I add to the UI?
Hard to explain...
Say I have a header (just 2 textviews) that will remain at the top and below that is a search box and button (main.xml). The user searches and I have it display the search UI (search.xml). This UI will have the same header (2 textviews) and below it will have several textviews each one containing a search result... Kinda like if you search for an app in the market. There's no way of telling how many results would be returned so I figured I would have to create each textview on the fly within the .java file. I'm not sure how to do this. Most likely would require a loop of some sort, but whats the syntax to create a new textview and display it right below the one above it? I'm working with linear here so I would assume just creating a new textview it will by default go to the next one down which is what I want.
Also, say I have 30 results... How do I get those to scroll but leave the 2 textview header in place? Would I create a ScrollView and put the new TextViews in that?

However I'm not a big java fan, although I can live with that, I would like to know if there're reasonable alternatives for the android virtual machine. I've done a medium sized project using clojure, however from the reviews I read, it's very slow when running on android. How about scala ? I read that some people did experiments with it in android, is it "fast enough" ? How big is the learning curve ?
