so everyonce in a while at the beginning of a phone call i get this crackling static sound till i hang up and retry the phone call then its fine didnt know what the cause of this could be?

I've had my phone a few days and have noticed a crackling when making regular calls at anything above around 65% volume. This seems to happen only on louder parts of speech. It's pretty frustrating when I'm in public and need the volume louder.

View 9 Replies View RelatedSo I've noticed some background hiss during voice calls on my Eris. I thought the update would fix it, but so far it hasn't done a thing.
Has anyone had this happen with their phone? I'm thinking of just exchanging it for a new one...
I have class A, with methods foo and bar, that are implemented by A1 and A2. The functionality in both A1 and A2 is the same. In other words:
public class A {
public int foo() { return 0; };
public int bar() { return 1; };
} class A1 extends A {
public int AnotherFooFunction() { return foo();
} public int AnotherBarFunction() { return bar();
} } class A2 extends A {
public int AnotherFooFunction() { return foo();
} public int AnotherBarFunction() { return bar();
} }
Is it better to keep the code in this fashion, or to swap out those virtual methods as static methods? (In Java, everything non-final/non-private is considered virtual, right?) According to the Designing for Performance section in the Android Developer Docs, I should swap out these virtual methods for static ones. So the above becomes:
public class A {
public int foo() { return 0; };
public int bar() { return 1; };
} class A1 extends A {
public int AnotherFooFunction() { return A.foo();
} public int AnotherBarFunction() { return A.bar();
} class A2 extends A {
public int AnotherFooFunction() { return A.foo();
} public int AnotherBarFunction() { return A.bar();
} }
Is this how it "ought" to be? I fully realize that I may be misinterpreting this paragraph in the docs.
I am totaly new to doing flashes and everything to cell phones. Last night I put 2.1 on my phone and it worked wonderful! Today I was going to root it with SPH-M900_MR2_DD03_REL-joeykrim-recovery-2.1.3.tar. I started up the Sprint Uploader thing and when it reached the actual updating part the USB cable got disconected form the computer. When I tried to turn my phone on it says "Cannot find .jpg or png!" I have tried to re-flash it but everytime it gets to the uplaod it freezes and has "?

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
i want to display a msg to the user (msg box or Toast) when exception happend in a static SQLite Database class that i use. the problem is that i cant call a non static method in a static class , how can i handle this. this is the class
private static SQLiteDatabase getDatabase(Context aContext) {
and i want to add something like this in the class when exception happen but context generates the problem of reference to non static in static class.
Context context = getApplicationContext();
CharSequence text = "Hello toast!";
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.show();
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!
I am modifying the source code here: http://thinkandroid.wordpress.com/2009/12/30/getting-response-body-of-httpresponse/
I get this error:
code:.............
This error is line 13 on the second box.
Anyone else getting a crackling sound out of their headphones when media volume is 100%? If I turn it down one notch the crackling disappears. Headphones are not the issues as I have verified this on 3 different pair. Im gonna see if my wifes droid does the same thing but figured I would post up and see what others thought.

View 2 Replies View RelatedI have a problem on my droid where when I use headphones it crackles and is really annoying. I have a pair of Bose over the ear headphones that have no issue on any other source however on the droid the crackling make me want to throw it across the room. Although many would jump to hardware, the catch is that it is only on random songs and the same ones each time. So it does it randomly on pandora on the same songs every time and not on any in my library but the actual external speaker will crackle on random ones as well. Maybe it will be addressed in 2.1? I know about the one at max volume but this is very different.
View 7 Replies View RelatedI 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:

Why should a static method in java accept only final or non final variables within its method, but not static?
For example I have the following method:

Not sure if this is technically the "silent bug" but calls do not even show up on the phone, they just appear as "missed call from...." no noise no other notification. I restarted phone but it did it again right away. Phone does show the 50% bug in battery info.

The screen doesnt light up and no options for receiving calls. This happened before I installed Google voice. I disabled Google voice and still no joy. Everything else works.

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..
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.
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).
This seems to happen mostly when I'm talking to one person, but every now and then I'll hear static on the line when I start to talk. Sometimes when I sniff it happens, or if we talk over each other. It doesn't happen on other calls, so is it the other phone perhaps?
View 22 Replies View RelatedAll of a sudden my speaker (the one you put to your ear) sounds really static-y. Not signal static, it's very clear that it's the speaker itself or at least something around it vibrating. It kind of sounds a speaker that has been damaged (ripped, or got wet or something even though it has not been wet).
Anyway, I plan on taking it into the sprint store today and having them check it out. Anyone one else with this problem?
Not sure if this is the right section but I have a quick question regarding NFC in android 4.0.4. I wondered if it was at all possible, either with an app or with some hacking to present a standard UID from the NFC, rather than generating a random code each time.
I am looking at using my handset on a door access system which traditionally reads the UID from a Mifare 2k card. If I could get it to present the same number each time I am sure it would work.
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).
I cant get the FM radio to work at all when I plug in headphones and turn it on all I hear is static no matter what station I goto. It would be real nice to get it working so I can use it while I'm walking. If I don't find a solution eventually I am going to take it into sprint and see if its defective and get and exchange for another Evo.
View 24 Replies View RelatedWhen starting a new Activity, I want to pass a complex object and do so by using this approach:
MyActivity.COMPLEX_OBJ = myComplexObj; // which is definitely NOT NULL! Intent intent = new Intent(); intent.setClass(this, MyActivity.class); startActivity(intent);
and then in MyActivity:
@Override public void onCreate(Bundle bundle) { if (COMPLEX_OBJ == null) { // report to Flurry ... } ...
}
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?
