[android-developers] Question regarding unexpected application behaviour (reported by market users)
Hi all, I just uploaded the application and got couple of negative rates like force closes on start. On start the tab page populated by Intent which is ListActivity. The list data is loading from resources. List is really small. No internet and file system access triggered on start. The strange thing is that I NEVER got such errors during the development and testing. The one reason I'm thinking I didn't check the device available memory... What else? Did you probably experienced such behaviour? Will appreciate your opinion.

[android-developers] Re: How can I show the escape characters of a xml file in my app
Here is some example.xml:
Person
Name Manoj/Name
class 10th /class
Genre male/Genre
...
/Person
The name field contains ' ' (Manoj as shown in the above example).
When I was parsing it using the DOM parser as shown in the previous
mail, I am getting only instead of Manoj. Not complete string I am
getting.
How to get the complete values ( even the node values contains ,
... etc escape sequence characters).
Can any one please help me.

[android-developers] Adding jpg into content resolver
I successfully adding a jpg file into ContentResolver by using insert, and I can query contentResolver to get information about the jpg file. But if I go to Pictures app, the new picture is not showing. I debugged into the code and found out that in the Camera source code, when it tries to generate bitmap for this new file, the BitmapFactory.decodeFileDescriptor(fd, null, options) sets the options.outwidth and outheight to -1. If I restart the emulator, the value will be correct 800 X 600. So, what do I need to do to make sure that after I generate a new file (.jpg) in SDCard and it will be shown in Pictures right away. I thought about using rescan of content provider, but because I might need to generate more than one jpg files at the same time, if they all call rescan, it might be a mess.

[android-developers] Detecting if microphone is mute during a call
Hello, I would like to detect if microphone in the device or in a headset is mute during a call. Currently I've taken the following approach (unfortunately - it does not work): 1) register PhoneStateListener to detect when a call is started/ finished 2) when call is started then I start a thread that periodically calls audioManager.isMicrophoneMute() method to discover a microphone status. (audioManager is obtained by calling getSystemService (AUDIO_SERVICE) ) 3) when call is finished I stop a thread started in bullet 2 Unfortunately audioManager.isMicrophoneMute() always returns 'true', does not matter if I select or deselect the 'Mute' option in the menu during a call. Does anybody know if it is possible to detect the state of a microphone during a call? I'd be very grateful for help.

Note also that some Java 5 idioms will allocate objects for you if you're not careful. For example, string concatenation like: myString = value of x is + x; Will allocate a temporary StringBuilder object each time this statement is executed.

[android-developers] Re: WebView.clearHistory()
I recently had the same issue. What I found is that you have to clear history AFTER the (first) page loads. It appears that the history clears everything before the current page so if your browser is at page A, you clear history and navigate to page B your history will be A B, not just B, but if you clear history when B finishes loading you will have only B. In my case I end up using onPageFinished method of the WebViwClient, but in this case you have to know what your start page is and clear the history only after it otherwise you will be clearing the history after every page navigated after the first.

[android-developers] Re: Unused java hardware acceleration on the G1 (was Re: Android game developers desperately need optimised game engine example code ...)
Yes, you are right, for many applications it may not be that critical. It rather reflects my own disappointment with the fact that whereas modern Nokia phones meet my real-time requirements with Java ME and offer satisfactory performance for users without any need to mess with native code, the speed loss of a factor 5-10 under Android means that my app isn't really usable under Android for some time to come. AFAIK there's nothing on the public Android roadmap either concerning a JIT compiler, or a native vector processing library with an Android API, and an ETA for the NDK is still missing, so there is currently not much point in planning ahead here when one needs more performance while maintaining CPU independence at the coding level (say for ARM and x86).

i checked another image which is ok but i really need to display that
image.
i am getting the path of the image from DB in activity A and passing
it in extra to activity B to set as imageUri to ImageView.
here is my code:
Activity B:
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.my_View);
loadSelectedImage();
}
public void loadSelectedUtter(){
Bundle extras = getIntent().getExtras();
if(extras !=null)
{
imageFile= extras.getString(image);
if(imageFile != null){
image= Uri.parse(imageFile);
imageicon.setImageURI(image);
}
}
}
}
ImageView
android:id=@+id/imageicon
android:src=@drawable/image
android:adjustViewBounds=true
android:maxWidth=291dip
android:maxHeight=55dip
android:layout_width=wrap_content
android:layout_height=wrap_content
android:layout_gravity=center
/
it loads the image for first time but gives exception on rotation or
2nd load.
plz advise if u have any alternative solution or how can i call recycle

[android-developers] Re: Android Physics Engine
I took a look at Anton's demo on a G1 device, and I was glad to see the integration of accelerometer as it really added value. I assume the calculations for collision detection and response are fairly basic, which allows for that performance. Simpull will also provide good performance for a scene of that nature (all verlet, no joints). At least I believe it will. The point where simpull becomes slow is when a more complex scene is in play with 10s of objects with many joints connecting some of them. Since the engine is all verlet and no rigid body dynamics, joints are one way to acheive a similar result, but with a very bad performance hit due to all the new temporary objects and new calculations. I would be super impressed to see a demo like Anton's with rigid body dynamics involved with at least some rectangles, if not other polygons and perhaps a joint or two. That is where the performance degrades quickly in my experience. On Apr 1, 2:45 pm, mscwd01 mscw...@gmail.com wrote: Thanks Lajos for pointing APE out, I hadn't heard of it until now.

The following is from the Manifest, and the resulting receiver gets the expected broadcasts: receiver android:name=.MyReceiver intent-filter action android:name=android.intent.action.DATA_SMS_RECEIVED / dataandroid:scheme=sms android:host=localhost android:port=6432/ /intent-filter /receiver The following is the code example that doesn't work (it does work with an intent like android.provider.Telephony.SMS_RECEIVED but not fordatasms): MyReceiver mReceiver = new MyReceiver(); IntentFilter mFilter = new IntentFilter (android.intent.action.DATA_SMS_RECEIVER); //also tried an empty filter intentFilter.addDataAuthority(localhost, 6432); intentFilter.addDataScheme(sms); context.registerReceiver(mReceiver, mFilter); The question is - why does this broadcast receiver get notified of the incomingdatamessages? It seems some other resource is notified when the Manifest version of the receiver is created...

[android-developers] Re: Capturing HEADSET_PLUG (android.intent.action.HEADSET_PLUG)
Sure... you need to implement two classes. One, derived from
BroadcastReceiver, which actually captures the broadcast. And, of
course, the service that keeps the receiver alive all the time. The
service is the easy part. You only need to override two methods:
@Override
public void onCreate() {
/* register receiver */
apr = new APReceiver(); /* replace this by your receiver class */
IntentFilter inf = new IntentFilter();
inf.addAction(android.intent.action.HEADSET_PLUG);
registerReceiver(apr, inf);
}
@Override
public void onDestroy() {
unregisterReceiver(apr);
}
Of course, apr (type of your receiver class) must be a private field
of your service class.
Then, you derive your receiver class from BroadcastReceiver and fill
in the onReceive method:
public void onReceive(Context context, Intent intent) {
if (intent.getExtras().getInt(state) == 0) {
/* HEADSET IS OR HAS BEEN DISCONNECTED */
}else{
/* HEADSET IS OR HAS BEEN CONNECTED */
}
}
However, you need to be aware that HEADSET_PLUG is a sticky event,
every BroadcastReceiver subscribed to that event will receive it upon
construction; I don't know if there is a possibility to determine if
the event has captured at the exact time or been sticked for a
while.
I hope, this short excerpt helps ;)

Hi all,
yesterday, I spent several hours trying to figure out how to capture
the HEADSET_PLUG intent with a BroadcastReceiver. The manifest defines
the receiver, with its intent-filter set to action
android:name=android.intent.action.HEADSET_PLUG /.
The receiver is working correctly (I verified that by changing the
intent filter to capture things like SMS_RECEIVED including the proper
permissions and the receiver fired as expected on receiving an SMS),
but when listening for HEADSET_PLUG, it never fires. Debugging the
whole thing is a bit complicated, as the emulator doesn't seem to
support headsets and I have to disconnect my target device (a HTC
Dream) from USB in order to attach a headset (so there's no logfile
viewing). Are there any special permissions required for applications
to capture the HEADSET_PLUG intent (and if so, which? I've tried
several, to no avail)?
Maybe the Dream doesn't fire such an intent at all (that'd be bad luck
for me), but I guess that it must be an issue related to application
permissions. The documentation says extremely little (well, actually:
nothing) about the single permissions needed to perform all the
actions described in the API docs, so this is absolutely something to
be improved.
What I want to do: Upon detecting a headset, I want to re-route the
ringtones from the speakers to the headset, so as not to annoy people
in my vicinity by a harsh ringing sound (I'm used to this behaviour
from my old phone) - by default, the speaker just keeps on ringing, no
matter whether a headset is attached or not. This part is already
working, but now I need to know how to detect headset attachment/
detachment events.
Thanks in advance,
Henning

Use a different image.
The G1 has a 320x480 pixel display. Your image is consuming ~41 bytes
per pixel...which seems a little high. More likely, it is a much higher
resolution picture than the G1 display can handle.
So, use a different image. Or scale down the one you have before
displaying it (and cache the smaller one to reuse on the rotation):
http://www.anddev.org/resize_and_rotate_image_-_example-t621.html
Also, call recycle() when you are done with the Bitmap, which may help
GC it faster.

[android-developers] Creating a private jar
I'm currently developping my own Android widgets. To help me in future projects and speed up my developments, I've been trying to create a private jar that contains all those widgets (that extend from Android classes such as View or ViewGroup). To do that, I created a project and included all files (.java and ressources) in this project. I exported this as a jar file. To test this jar file I created a new project and tried to include my widgets using an XML layout. Unfortunatly, it seems that the sytem does not see my ressources. Looking at the Android source code, I noticed that android.jar contains its own ressources so I assume this is possible. I'm sure I've done something wrong...but what? What is the problem? And how to solve it? Thanks --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Creating a private jar
Looking at the Android source code, I noticed that android.jar contains its own ressources so I assume this is possible. Yeah, but that's special. There is no way for JARs written to support SDK-level applications to embed resources that I have found. Instead, you need to package your resources separately (e.g., a ZIP file) and distribute them for reusers of your JAR to unpack in their APK project's res/ tree (or to replace with their own editions of the resources, as they see fit). Then, adjust your API to accept resource IDs as parameters (like you see for many of the APIs), so your code no longer has R.id or R.drawable references itself -- those refererences would be in the calling application, who has the resources and the corresponding R.java file. If there's another way around this, I'm certainly interested to hear about it... -- Mark Murphy (a Commons Guy) http://commonsware.com _The Busy Coder's Guide to Android Development_ Version 2.0 Available! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: java.lang.NoSuchMethodError in Eclipse layout editor
For the time being, I have gotten around this problem by having a
second initializer which calls the methods that are throwing the
problems.
I believe this is a bug, to be honest. At the very least, if there
are separate classes for the actual Android SDK and the Android SDK
that Eclipse uses, I would think that the layout editor should catch
these exceptions. Why the Paint class would have setStyle() available
and not setStrokeJoin() available in the 'separate' SDK is beyond me.
Does anyone know how to report a bug?
On Mar 30, 11:40 pm, Matt matthew.quig...@gmail.com wrote:
In thelayouteditor inEclipse, I have created a custom view. For
some reason, there are a few methods which cause NoSuchMethodError

mPaint = new Paint();
mPaint.setAntiAlias(true);
mPaint.setDither(true);
mPaint.setColor(0x);
mPaint.setStyle(Paint.Style.STROKE);
try {
//mPaint.setStrokeJoin(Paint.Join.ROUND);
//mPaint.setStrokeCap(Paint.Cap.ROUND);
} catch (Exception e) {
}
mPaint.setStrokeWidth(12);
The code which is causing no such method exceptions are the ones
surrounded in a try-catch. By the way, the try-catch does NOT stop
thelayouteditor from getting the exception (and therefore failing to
render).
Does anyone have any clue of why a few methods on the Paint class are
throwing errors?

[android-developers] Socket problems: broken pipe
Hi all,
I create and open a socket like this:
try {
socket = new Socket();
InetSocketAddress addr = new InetSocketAddress(hostName,
port);
socket.connect(addr);
dis = new DataInputStream(socket.getInputStream());
dos = new DataOutputStream(socket.getOutputStream());
} catch(IOException e) {
state = PEConnectionStateError;
Log.d(TAG, Open failed, e);
return false;
}
which succeeds. Later on, I try to write a message to the socket,
which consists of
super.writeToStream(os); // writes two ints
os.writeInt(version);
os.writeInt(flags);
os.writeUTF(sessionId);
os.writeUTF(clientId);
os.writeInt(sequenceId);
os.writeInt(sequenceHash);
At the writeInt(flags), I get a java.net.SocketException: Broken pipe.
I'm not sure, but I don't think the server ever sees the connection. I
do have uses-permission android:name=android.permission.INTERNET /
in the manifest.
Is there some sort of setup I need to do in Eclipse or the emulator to
get this to work? Has anyone else gotten a sockets app working?

[android-developers] Best way to draw street name on a maps app
Hello all, I'm working on a maps application that draws streets from vectorial data using OpenGL. I encountered a bottleneck while drawing street names; as OpenGL can't render fonts by it's own, I followed the SurfaceOverlay API demo and put another view on top of the GLSurfaceView. The problem is that drawing something like 80 texts using canvas.drawTextOnPath() takes 1.2+ seconds, which is unacceptable (drawing 300 lines takes around 130ms). Any suggestions on how to do work this out? I was thinking of drawing every character as a series of lines in OpenGL, but it sounds pretty painfull.

[android-developers] Debugging in Eclipse - current line wrong for methods with multiple return points
Hi,
While doing debugging with Eclipse I noted that the debugger
highlights the wrong line as next line to execute for methods with
multiple return points. It fools the developer that the last line of
the method is executed, where in fact it is not.
Does anyone know if this is some kind of known issue? My colleagues
have also experienced this but we have never seen it when doing on-
device-debugging on e.g. the Sony Ericsson SDK.
I couldn't find anything at http://code.google.com/p/android/issues/list
There was a similar post in android-beginners 2007-11-25. No replies,
though.
http://groups.google.com/group/android-beginners/browse_thread/thread/60277af9bdca002f/805692d0e6689c6e?lnk=gstq=John+Wiedey#805692d0e6689c6e
Any help would be deeply appreciated. It seems hard to know where in
the tool chain to begin looking for the problem.
Br, Jesper
Steps to reproduce (works with both emulator and dev phone 1)
1. In the code below, set a break point at line 18: if (i == 1) {
2. Project, Debug
3. If prompted select Android application and target device
4. Debugger will stop at line 18
5. Press F5 (step into) - debugger advances to line 19: return 0;
6. Press F5 again. Now the debugger indicates that the next line to be
executed is 22: return 1 which is wrong.
7. Press F5 again and you are back to line 14 in calling code as
expected.
If the code line 12 is modified so that the call is m(2), the if-
statement is not executed and the debugger is correct. A similar
example can be made with a try-catch where it looks like the last line
of the catch block is executed even if no exception is thrown.
Code (first line is line 1)
package com.wayfinder.example;
import android.app.Activity;
import android.os.Bundle;
public class DebugProblem1 extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
m(1);
setContentView(R.layout.main);
}
private int m(int i) {
if (i == 1) {
return 0;
}
return 1;
}
}
Environment
SDK 1.1
Eclipse 3.4.2
ADT installed and used.
More details including dump available on request.

[android-developers] How to display soft keyboard unlock screen for keyguard in cupcake
Hi, I'm trying to write customized unlock screen for use in the keyguard window. This unlock screen has a TextView with inputType=Text and in a normal test Activity, the soft keyboard pops up when it gains focus. However, when running in the context of the KeyGuard as part of unlockscreen view, it's never displayed. When the unlock screen is finished, I can see the soft keyboard behind it and disappears quickly. It seems that the soft keyboard is behind the unlock screen all along. I searched around in the source code and found some constants for window layers in PhoneWindowManager.java based on window type, and KEYGUARD_LAYER is almost at the top, above INPUT_METHOD_LAYER. Can I switch the layer numbers to make it work? Is there a way to force the soft keyboard to be shown on the top in context of the keyguard? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

The MOUNT_UNMOUNT_FILESYSTEMS permission is set in the manifest. And yes, I really do want to write to the SD card; I don't want to use the logging features Android includes for this particular application. The Android documentation does not seem to give any specifics on how one might write files to removable storage in Data Storage under Framework Topics. What am I doing wrong, or where can I read more about this topic? If you are running this on the emulator, do you have an SD card image set up? The emulator does not have SD card storage by default -- you need to use mksdcard to create an image and then tell the emulator to use that image via a command-line switch at startup. -- Mark Murphy (a Commons Guy)http://commonsware.com|http://twitter.com/commonsguy Warescription: Three Android Books, Plus Updates, $35/Year- 隐藏被引用文字 - - 显示引用的文字 - --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] How to compensate for gravity when using the accelerometer?
I am trying to write a simple app that calculates velocity based on the current acceleration (between sampling times). I have no problem obtaining the device’s acceleration from the accelerometer, nor calculating the velocity based on the reading. My question has to do with how to compensate for the fact that gravity (or the normal to gravity) is always part of the force exerted on the device. In other words if we were in space (or in microgravity), the device would have 0 acceleration on each axis when at rest. Moving the device, would show the corresponding acceleration and thus a simple calculation would derive the velocity. I read something about a Kalman filter to either low-pass or high-pass filter the change of acceleration. The only conclusion from that information was to use a high-pass filter to recognize the gravity vector then subtract that vector from the total acceleration vector. Does anyone have any sample code that shows how to account for gravity to obtain the net acceleration vector (once gravity is removed)? Maybe I am looking at this from the wrong reference frame… Should I instead use the GPS to obtain locations and calculate an average velocity based on distance over time? Maybe a combination of both?

[android-developers] Paying $50 for someone to design an application...
I am not much of a programmer...my last programming class was FORTRAN. But I love this phone with the exception of one problem: I hate the autolock feature of the phone. http://androidforums.com/application-requests/4517-paying-50-app.html I can provide references via eBay or the Corvette Forums as to my credibility that I will pay immediately upon usage of an application that does this very simple action: Simply turn off the default autolock feature. As it stands now the phone locks once the screen times out. This battery is not good enough on the G1 to leave the backlight on at all times nor should it be necessary. Yes I realize you only need to hit the menu button twice but that gets annoying when texting back and forth. I have tried Autolock and Lock 2.0 and neither fulfills this requirement. I look forward to hearing from you. You can contact me at matthew.a.jo...@us.army.mil or on the forums that I provided above. I am not the only person with this problem. It should have been an option from the get-go to turn off or leave on. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Adding IM providers to native IM app
I'm just looking at the Android's native IM app and wondering if it's possible to create new providers? I know other people have written seperate IM clients but it'd be great to add to list in the native IM app. The 3 I'd like to work on is Facebook, MySpaceIM, Skype. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] How does prelink-linux-arm.map work?
Hi, I got some diopen() fails in my native library. I guess the reason is insufficient memory. I conduct some experiments by exhausting the memory and then dynamically load some .so files. Yes, dlopen() failed again. At first I thought the .so files listed in prelink-linux-arm.map are libraries pre-loaded into memory, and dlopen won't fail if the target is in the map. However, that's not true. Anybody here knows what's the use of the map? Or where did I go wrong? Thanks.
