HTC Incredible :: Having Hissing - Static Noise On Headphones

May 10, 2010

I'm experiencing a static/hissing noise on headphones with my incredible. This is particularly noticeable on the small in ear headphones/earbuds during quiet portions of music, or if you have music playing and turn the volume down to zero, and for a short time after pausing music (until the audio jack is powered down. Is anyone else having these issues? Can anyone confirm that some phones do not have this issue?

I love the phone but this is almost a dealbreaker for me as it somewhat kills the whole idea of not needing a separate music player, though it can be somewhat worked around by headphones with online volume controls, decreasing volume by about half and boosting iron the phone.

HTC Droid Eris :: Headphones Calling People

Jan 20, 2010

So on my way to class the other day listening to the media player in the car was just fine, I plug it in to one of those little FM transmitter things and it bounces along under my e-brake handle just fine. But when I parked my car and plugged in my headphones things went bonkers. It started skipping tracks, fast forward, and rewinding tracks, and finally started calling people, I called a friend of mine 4 times. When it started doing it again tonight I did some investigating and discovered that it's recognizing my headPHONES as a headSET. I tried it with my roommate's headphones and it started as headphones but if I twisted the plug the little microphone would appear.So I guess this is a 2 part question.

1.) Can I turn off the microphone of a headset through the phone?

2.) Has anyone else encountered this problem and how did you fix it?

Ok that's 3 parts but who's counting.

I would like an app that shows me on a map which cell tower my phone is using, signal strength, etc.

Android :: Getting Cell Signal Strength For Current Cell Vs Neighboring Cells

Jan 6, 2010

I'm writing an android application that collects cell signal strengths.I am having trouble getting the "current" cell signal strength, but I don't have any problem getting the "neighboring" cell signal strengths.To get the current cell signal strength, I created a PhoneStateListener and implemented the onSignalStrengthChanged callback.It works, but not very well.It seems like the signal strength hardly ever changes, and resolution jumps to only a few numbers.I would accept the answer that the resolution of the signal strength hardware is coarse, but when I use the TelephonyManager's getNeighboringCellInfo() method, it works much better.The signal strength readings from neighboring cells change frequently, and they have much better resolution.So, how can I get the current cell signal strength in the same way that I am getting the neighboring cell strengths?It seems odd to me that the functionality of the neighboring cells is better than the current cell.

Android :: Cannot Make Static Reference To Anon-static Method

Feb 7, 2010

I'm having some issues with the old "Cannot make a static reference to a non-static method" error in my Android program. I am creating a sand falling game (similar to the Powder Game) and I created a class called Control to create a Control Bar at the bottom of the screen with a slider for brush size (that works fine) and a button to pop up a Dialog to allow users to pick the selected element. However, when I call DemoActivity.showDialog(2) from my code, it gives the static reference to non-static error (DemoActivity is the main activity of my application). I also tried changing it to just Activity.showDialog(2), but I got exactly the same error!

Here's my code:

CODE:................

I fixed it by adding the following to my Control.java code:

CODE:..........

And then calling control.setActivity(this); from my onResume section of DemoActivity.java!

Replace Single Row View In Custom STATIC ListView - STATIC Data

Mar 18, 2013

I have Eclipse Juno and I'm working on an app with that.

The main activity will have a scrollable menu that takes you to all the other activities.

So the general structure/outline right now:[HIGH]Relative Layout ImageView (header logo type thing) ListView (the actual scrollable menu)[/HIGH]Here's the problem though... I can't find any simple list tutorials. I can easily make a single line list work but I need to make a two line list and one that is static, not dynamic and no examples are out there for that. It's like if you want to make a 2 line list, you can only learn how to do it in the most code-heavy ridiculous way possible.

Essentially what I am looking for with the list is this: Item one: Centred, bold, non selectable title (Resources)

- Item two-??: two line list items, click-able to a new activity, title of the section on first line, description on the second line.

- Item ??: Centred, bold, non selectable title (Tools)

- Item ??-??: two line list items, click-able to a new activity, title of the section on first line, description on the second line.

Nothing dynamic that is ever going to change, no super complex wonkey calculations, just to simply have the data set in stone (preferably via XML) and to call it into the list.

I experimented with some of the other list views and no matter what I did, I could get, via editing the resources and NOT using Java, more that one item on a single line but it wouldn't format it properly according to the layout I guess because I haven't got the ID correct or whatever I don't know.

I mean, all the examples I've seen for a 2 line list are extraordinarily over-coded and just bloated. I mean I have a website I am still working on in C#/ASP.net that has far more complex things in it with half the code that I've seen for the examples of the two line lists.

I tried on my own to figure it out (I am decent with C# and vaguely familiar with Java, self taught, and programming for some other systems like Python, again all self-taught), but like ALL coding references, they're organised by the actual code you implement (that you don't know) instead of by what you want it to do (so you have to search the whole code base to find something that you don't know what it's called but know what it does). >:C

Android :: Static Vs Non-static Inner Classes

Mar 9, 2009

I have been finding it convenient to extend Handler in many of my activities to handle messages specific to the activity. The handler sublass is an inner class of the activity and needs to access its state. I am wondering if there is any performance difference between making the handler subclass static and passing in the activity explicitly in its constructor or making the subclass an "instance class" and letting the vm worry about my accessing members of the containing activity.

The static approach:

Android :: Neighboring Cell Signal Strengths Better Than Those For Current Cell Signal Strength?

Jan 6, 2010

I'm writing an android application that collects cell signal strengths. I am having trouble getting the "current" cell signal strength, but I don't have any problem getting the "neighboring" cell signal strengths. To get the current cell signal strength, I created a PhoneStateListener and implemented the onSignalStrengthChanged callback. It works, but not very well.

I would accept the answer that the resolution of the signal strength hardware is coarse, but when I use the TelephonyManager's getNeighboringCellInfo() method, it works much better.

It seems odd to me that the functionality of the neighboring cells is better than the current cell. Am I missing something here?I would also like to directly call a method from the telephony manager to get current cell strength, as opposed to a listener, if possible. If anyone knows how, please let me know.

Android :: JOIN Contact People And Contacts / People.Phones

Aug 28, 2009

I have an app where I want to list all phone numbers and the associated contact name.I see that there is the Contacts.People table for the purpose of getting all phone numbers and that there is a PERSON_ID to allow me to lookup the contact in Contacts.People.Great.Now I see that all the columns I want are already joined to the Contacts.People.Phones table. But that seems lucky in this case.How could I do the equivalent of the above statement in general if the implementer of the content provider hadn't been so nice as to join for me?

HTC Hero :: People - Contacts - Pictures In My People Update With Facebook

I have all of my contacts linked to their respective facebook accounts, but the pictures that show up when I go to my People never update with the facebook pictures, they have stayed the same since the day I linked the two regardless of how many times the person has changed their default picture since then. Is there any way for me to change this so the pictures in my People update with facebook? Since they are linked I assume they should be able to do this.

Android :: Static Compilation

Sep 11, 2009

I was working on Freescale iMX31 board, I ported android and it was working fine , but when it came to integration of WiFi & Bluetooth, android forum recommended me to do static compilation for porting over android !

Can I know why some drivers have to be statically compiled before it is ported over android? It was not the case with other drivers which when integrated with android, they worked perfectly well like serial port, usb etc..

Android :: Is The Static Safe ?

Jul 29, 2009

I use a single static class in my code that defines a static field which I'm reusing between Activity onStop/onStart invocations. Here's a scenario:

User clicks on "Authorize" button (static data is initialized) Activity is stopped and web browser is called
Browser executes callback and Activity is restored (static data is reused)

At least one of my users reports the failure at step 3 which I cannot reproduce but which looks like reset of static data.

Android :: App Static Storage ?

Sep 30, 2010

I am creating an Android application which will have some embedded music inside of it ( ~ 80 MB ). I was planning on putting it in the res/raw folder.

Since android stores that all in it's internal memory, is this way too large? What are my options? I have come up with the following:

Copy resources out of internal storage and onto the SD card when application first starts. Afterwards remove from internal storage (is this possible?)
Download music from the web when the application first starts.

I would really prefer not to have to go with option 2 since I want the app to be entirely offline and the static music is not going to change (except between releases).

Android :: Mic Audio Capture Too Static

Jun 3, 2009

As a first step toward a speech recognition project, we wrote a simple voice recording application based on the information in this thread:
http://groups.google.com/group/android-developers/browse_thread/threa...

It is working; however, the audio is extremely poor too static for our needs. As a comparison, we did a similar audio file captured with audacity on a PC and it was much better. Has anyone been able to record high quality audio with the android dev phone? According to the documentation of MediaRecorder, there is only one audio encoder "AMR (Narrowband) audio codec" and three output formats--3gpp, mpeg, and raw AMR:
http://developer.android.com/reference/android/media/MediaRecorder.html

According to wikipedia, AMR encoding is only 8hz. Is there a better option available perhaps a lower-level API compared to MediaRecorder? We are testing on Windows XP, with a Logitec USB microphone, eclipse ganymede, and we are using all the defaults for an android 1.5 app (no emulator command-line options. We defined the SD card in AVD manager).

and then in MyActivity:

@Override public void onCreate(Bundle bundle) { if (COMPLEX_OBJ == null) { // report to Flurry ... } ...

Android :: Static Variable Instantiation

Apr 1, 2009

I have noticed in my application(s) that after a call to Activity.finish() that the static variables that I declared in my classes still hold the values that they were changed to during the activity's life cycle. Upon the re-launch of the activity, the program does not re-instantiate the variables as declared or set them to the default java behavior. Is there something that I can do to cause this to happen, other than re-setting every static variable in my application?

Android :: Use Of Static Finals In Activity

Sep 8, 2010

Why is the use of static final variables encouraged to declare constants over just final variables? The use of static sounds logical when there will be many instances of a class but is this argument correct when used for a Android activity. In fact, since the Class instance will be around even after the activity finishes and is eventually garbage collected, it seems like all these constants will still be in memory until the class loader is around. Also, does the compiler inline non-static final variables(ints and String) just like it does for static final variables?
