[android-beginners] Re: MediaPlayer Volume Range
Thanks Dave. Although when I tried putting 100 in the setVolume method clickSound.setVolume(100, 100); The volume level in the emulator seems to be louder when compared to 1.0. Any idea? -Marc On Thu, Jan 8, 2009 at 10:39 AM, Dave Sparks davidspa...@android.comwrote: The range is 0 to 1. You can use any increment you want to create a logarithmic volume scale, just make full volume 1.0. Multiply be a scalar less than 1.0 to get the next lower volume. Multiply that volume by the same scalar to get the next one. Repeat until you have enough values. The number you choose for your multiplier will vary according to purpose. For example, the Android music volume control is much finer grained (32 steps?) than the notification volume control (8 steps?). To get a smooth fade, you probably want to use 1dB or less (1dB = ~0.89).

[android-beginners] Installing new packages out of my own application
Hello, I'm new to Android development and don't realy know about how to use all the given functions. What I want to do is to build a tool (only a proof of concept) to manage installation of new packages. The thing is I can't figure out how to install a new package. First I added a uses-permission tag with the value android.permission.INSTALL_PACKAGES into my packages manifest file. I've found the function installPackage(Uri uri) inside the PackageManager class. So I tried to use it this way: Uri.Builder uribuilder = new Uri.Builder(); uribuilder.scheme(http); uribuilder.path(//hostname/SamplePackage.apk); PackageManager pm = getPackageManager(); pm.installPackage(uribuilder.build()); What happens is that my application crashes. Using the debuger I figured out that a NullPointerException occurs inside the PackageManager class. The next way I tried to install a package is using the already existing Package Manager. So I created a new Intent to call the Package Manager and called StartActivity with this Intent: Uri.Builder uribuilder = new Uri.Builder(); uribuilder.scheme(http); uribuilder.path(//hostname/SamplePackage.apk); Intent intent = new Intent(Intent.ACTION_PACKAGE_INSTALL, uribuilder.build()); startActivity(intent); But also this method ends with a NullPointerException. What am I doing wrong? How can I get this job done? I don't have a real phone to develop on, only the Android emulator. Maybe the emulator doesn't support this function or this Intent!?

[android-beginners] How can I debug this?
I've go tthe following code:
CODE
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.listlocations);
//set up our ContentProvider
locationsCursor = managedQuery(Provider.Locations.CONTENT_URI,
FIELDS, null, null, null);
locationsCursor.moveToFirst();
ListAdapter adapter = new SimpleCursorAdapter(this,
android.R.layout.simple_list_item_1,
locationsCursor,
new String[] {
Provider.Locations.NAME},
new int[] {R.id.name
});
setListAdapter(adapter);
selection=(TextView)findViewById(R.id.selection);
}
}
/CODE
It appears to be working. I get what looks like two elements in a list and
I can click on them but I'm not seeing any text in the fields. My
ContentProvider has two records and I can assign the values to variables, so
I know that's working. I can't figure out where to go from here to make it
work.
Also, to debug this, should I be using DDMS? Right now I'm using an Eclipse
Debug Configuration becuse I can't see how DDMS can help me.

Could you advice me on how to complete my code? Thank you.
I'm going to be tackling the same sort of problem in an app I'm working
on so I can't give you much advice. BUT, I can tell you that typically
with HTTP file transfers, you'll want to encode the file into base-64
format. Unfortunately, for whatever reason, Android does not include
that capability as far as I know. Oddly, there's a bit of code in the
Apache Commons/Jakarta project to do that, but it wasn't included in
Android with the other code borrowed from that project. So what I did is
download the following files from the Apache site (I grabbed them
directly out of the source repository browser at
http://svn.apache.org/viewvc/commons/proper/codec/trunk/src/java/org/apache/commons/codec/
) and create new packages within my app's project:
BinaryDecoder.java
BinaryEncoder.java
Decoder.java
DecoderException.java
Encoder.java
EncoderException.java
StringDecoder.java
StringEncoder.java
StringEncoderComparator.java
binary/Base64.java
binary/Base64InputStream.java
binary/Base64OutputStream.java
binary/BinaryCodec.java
binary/Hex.java
I needed to create two packages: org.apache.commons.codec and
org.apache.commons.codec.binary from those files; it should be easy
enough to guess which ones go where. :-) From that point, base-64
encoding or decoding is as simple as including the packages, and
calling Base64.encodeString() or Base64.decodeString(). There are
multiple encoding/decoding functions there to suit your needs.
Raymond
P.S. I'm hoping that Google or some coder will include these classes in
the Android sources in the future, which would make us using it like
this unnecessary. Time will tell...

I have no idea if the latter approach can work (there are some hiccups with having focusable items in list elements), but it's not out of the question. -- Mark Murphy (a Commons Guy) http://commonsware.com _The Busy Coder's Guide to Android Development_ Version 2.0 Published! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

Hi all.
I'm following through the notepad tutorial. I'm in Exercise 1 and in step 5
it says at the end of step 5:
http://code.google.com/android/intro/tutorial-ex1.html
Open the R.java class in the project and look at it, you should see new
definitions for notes_row and text1 (our new definitions) meaning we can now
gain access to these from the our code.
I don't have these new definitions as far as I can tell. I'm learning the
interface of eclipse at the same time, so I might not be looking in the
right place. Here is the contents of my R.java:
/* AUTO-GENERATED FILE. DO NOT MODIFY.
*
* This class was automatically generated by the
* aapt tool from the resource data it found. It
* should not be modified by hand.
*/
package com.android.demo.notepad1;

public static final class drawable {

}
public static final class string {
public static final int app_name=0x7f04;
public static final int no_notes=0x7f040001;
}
}
I'm looking under Notepadv1 src com.android.demo.notepad1 R.java in
the Package Explorer. Can anyone suggest why my new definitions are not
there?

[android-beginners] spinner blues
I have tried putting a spinner in an app, both from books and several
online tutorials, and it keeps locking up. It seems like my emulator
doesn't like when I set the adapter the the array list. I even made a
test project just to try the spinner itself, but to no avail. I'm
doing the same code that others say work, but it doesn't for me. Any
ideas?
Here's the main XML:
?xml version=1.0 encoding=utf-8?
LinearLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:orientation=vertical
android:layout_width=fill_parent
android:layout_height=fill_parent
TextView
android:id=@+id/test_result
android:layout_width=fill_parent
android:layout_height=wrap_content
android:text=@string/hello
/
Spinner android:id=@+id/spin
android:layout_width=fill_parent
android:layout_height=wrap_content
android:drawSelectorOnTop=true
/
/LinearLayout
...the code:
import java.util.ArrayList;
import java.util.List;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.TextView;
public class SpinTest extends Activity {
TextView testResult;
private ListString allUnits;
Spinner spin;
ArrayAdapter String adapter;
private String[] units = { Carrier, Battle ship, Cruiser,
Destroyer, Frigate, Submarine, Boomer };
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
testResult = (TextView)findViewById(R.id.test_result);
Log.d(onCreate, testResult id found);
spin =(Spinner)findViewById(R.id.spin);
Log.d(onCreate, spinner id found);
allUnits = new ArrayListString();
for(String s: units ){
allUnits.add(s);
}
Log.d(onCreate, arraylist created);
adapter = new ArrayAdapter String (this,
android.R.layout.simple_spinner_item, allUnits);
Log.d(onCreate,new adapter made);
adapter.setDropDownViewResource
(android.R.layout.simple_spinner_dropdown_item);
Log.d(onCreate, adapter layout set);
spin.setAdapter(adapter);
Log.d(onCreate, spinner adapter set);
setContentView(R.layout.main);
}
}
...and finally, the last portion of the log:

So should we report that? Any reaction, google employees? -M On Fri, Jan 9, 2009 at 11:48 AM, Dave Sparks davidspa...@android.comwrote: I took a quick look at the code, and it looks like we're not clamping the values. If I'm reading the code correctly - not easy because there are a lot of layers between the Java client and the audio output - it looks like some nasty wrapping effects will occur if you use values higher than 1.0. I would consider that a bug in the code. I suggest sticking to values between 0 and 1. On Jan 8, 3:41 am, Marc Lester Tan mail...@gmail.com wrote: Thanks Dave.

Any idea? -Marc On Thu, Jan 8, 2009 at 10:39 AM, Dave Sparks davidspa...@android.com wrote: The range is 0 to 1. You can use any increment you want to create a logarithmic volume scale, just make full volume 1.0. Multiply be a scalar less than 1.0 to get the next lower volume. Multiply that volume by the same scalar to get the next one. Repeat until you have enough values. The number you choose for your multiplier will vary according to purpose. For example, the Android music volume control is much finer grained (32 steps?) than the notification volume control (8 steps?). To get a smooth fade, you probably want to use 1dB or less (1dB = ~0.89).
