Android :: Public Service To Report / Dispatch And Resolve Repairs
Jul 4, 2009
http://code.google.com/p/fixxit/
I had an idea to use Android in the public space to report public works and other problems that need repairs. Android provides a great tool to document and locate problems. Google APIs like Maps and Appengine can link these reports to help direct efforts to make the public space a better place to live. Unfortunately I'm a Java rookie and so lack the skills to even start the coding at this point. How to get this open source application started.

I want to create a service that runs on Android which can collect all of my location information. Either write the information to a file or send to a server using 3G/wiki network. I was thinking about using a service that runs forever as a daemon. After reading "Diamonds are forever, services are not" by Mark Murphy, I realized that it is not a good idea. However, I need to somehow acquire the moving trajectory information on the Android phone. Without a daemon service running forever, how do I do that ?

Is there a way that a Service can report back to the calling activity when the Service has reached a particular stage of processing? Consider a music player activity that initiates the actual music playing in the background as an Android Service. I want to detect and inform the Activity when the Service has reached the Mediaplayer's onPrepared. Is there a way that the Service can tell the calling Activity when the MediaPlayer's onPrepared is called, to let the Activity know that the audio is prepared and ready to play?I am basically looking to see if there is work around, rather than having a thread in the activity, pinging constantly to check if the Service has reached onPrepared.

I am sending my HTC Hero (Orange UK) back to HTC for them to tinker with it as it has had absolutely terrible reception for pretty much the entire time that i have owned it.
I had been waiting with each new OS to see if the problem would be fixed. The problem is that the signal fluctuates wildly without manipulating the phone, it will cut out whilst i am on the phone and just resting it on a table it will lose signal for perhaps a few minutes each half hour.
Spoke to Orange on the phone and they said to send it in for repairs to HTC.
Now, my phone has a two cosmetic bumps on it - one graze on the top corner and a tiny gouge on the bottom corner. These are purely cosmetic and I am sure that these have nothing to do with the problem, as it existed before those accidents.
I guess what I am looking for are your experiences with HTC repairs - are they the sort of firm who look for any excuse to claim that you caused the damage and void your warranty?
If they do claim that the signal problem is my fault, is the burden on me to prove that I did not cause it, or them to prove that I did?

So my screen is freakin wrecked. I dropped it from about 2 feet into a pile of leaves. I picked it up and dusted it off and didn't see any problems. I took it in side and set it on the table and came back in 10 minutes and had a crack running about 2.5" diagonally across the screen and a little one in the corner. After about an hour another one showed up running horizontally across the screen.
I find it hard to believe that the fall it took would cause the glass to shatter like it did. I think it might have been the temp difference of bringing it inside.....>90 to ~68. Should I contact VZW or HTC first? Any recommendations on 3rd party repairs?

Does anybody have any idea why I get often(but not always) error during the on touch event? Handling touch events is freezed for few seconds(this appears only immediately after application start). Then Error screen appears (choose wait of close). When I choose wait after few seconds screen is starting to process events. I'm using surfaceView with thread for painting. In logcat I get something like : "No window to dispatch pointer action 1".

I found event handler: dispatchTouchEvent(MotionEvent) works differently between G1 & emulator when finger is holding on touch screen.
I have a class inherited from RelativeLayout and override public boolean dispatchTouchEvent(MotionEvent event) method. After I touch & hold on the touch screen, in emulator I got MotionEvent.ACTION_DOWN event only. But in G1, I got MotionEvent.ACTION_DOWN first and then MotionEvent.ACTION_MOVE continuously, even if I try my best to hold still my finger tip.
I wonder if this is because there is pressure field in the MotionEvent. Because the blood pressure on finger tip changes continuously with heart beat, so no matter how still my finger is, the pressure value still changes. But I wonder if all kinds of touch screen have pressure factor in their touch event? Will all touch screen driver emit touch event continuously when finger is holding on the screen?

I'm the PC admin for a Public Library in Florida. I keep the labs running. I have NO experience with Android. We never have enough PC's for the public at peak times. Putting in more PC's is expensive, or even impossible in some buildings. I'm always looking for ways to serve more patrons cheaply. Portable PC's are an idea for getting around this, but have problems. Notably, some are going to get stolen. All of them will get used heavily and often by people without the necessary skills to keep their data private. Sometimes they get used by our young hacking community for naughty things. I saw the Cherrypal PC and got interested. These things are ultra-cheap. That's enticing.
So here's my big question: How do I lock down an Android public PC? Specifically I need the machine to boot or log to a state that's exactly what I want EVERY time a new user comes on. There can be no remaining information about the old user (credit cards, passwords, chat history, etc.) that the next user can steal. Can I lock down the PC's? Is it easy and fast to restore to a base state that has the homepage and appearance that I want for the library, while keeping away changes I don't want? Is there anything that would keep Android from being a good addition to public PC's in the library?

I'm currently working on an application which need security features. My question is simple, if every application is signed by its developper, how can I access application public key? (and private).

I have this code:
hubSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parentView,
View selectedItemView, int position, long id) {
final MediaPlayer mp2 = MediaPlayer.create(Textbox.this, R.raw.hero);
mp2.start(); } public void onNothingSelected(AdapterView<?> parentView) {
} } );
(The code basically runs when a new item is selected of a spinner and then plays a song, which later will be a variable based on what was picked, but I'm fine as it is for now). And I want to be able to use 'mp2' out of this public void, (I want a button which pauses it). How can I do this?

iFMW was upgraded: Mobile site for public person or private file share for secret person in one app.
It has two inversion functions on one app.
Public person can get his/her own public web site on the phone and secret person can use only private file sharing directly on the phone without uploading.
Those who want two demands above will use whole functions.
What will you choose of those choices?

I'm working on an app that is meant to be used by fans of a sport team. In the future, I expect to use the same app but for any different team. So, what changes would be the colors, team logo, app name and the like. So, is there any technique that allows me to build binaries for different teams without having duplicated resources?

I am using a Mac with Eclipse Galileo, trying to load Android code from a public repository. I tried 'Checkout from SVN' and the URL is:
http://secrets-for-android.googlecode.com/svn/trunk/secrets-for-android-read-only
This is from the website:
http://code.google.com/p/secrets-for-android/source/checkout
I get the error:
Error validating location: "org.tigris.subversion.javahl.ClientException: Bad URL passed to RA layer
svn: URL 'http://secrets-for-android.googlecode.com/svn/trunk/secrets-for-android-read-only' non-existent in revision 114"
Keep location anyway?
I'm currently using this svn client in Eclipse to manage my own secure repository on another website, so I know it's installed correctly and works.

I'm a bit new to programming Android App's, however I have come across a problem, I can't find a way to make global variables -unlike other coding like php or VB.NET, are global variables possible? If not can someone find a way (and if possible implement the way into the code I will provide below) to get a value from the variable 'songtoplay' so I can use in another Public Void...
Here is the code:.............
Basically, it gets the value from the Spinner 'hubSpinner' and displays it in a Toast. I then want it to return a value for string variable 'songtoplay' -or find a way to make it global or useable in another Public Void, (Which is will a button, -loading the song to be played)

Looking at the example code in the docs
http://developer.android.com/reference/android/content/Context.html#getExternalFilesDir%28java.lang.String%29
File path = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
It does not compile on 2.1. The static fields DIRECTORY_PICTURES, DIRECTORY_MUSIC etc. Don't seem to be found. Using the filter api checkbox, I see that it was removed in Android 2.2 (or api version 8). So the manifest file needs to contain minSdk defined as 7.

After finishing my android application development I used the command showing below to get private key, but it shows some errors such as "The Keystore was tampered with or password was in correct".
$ keytool -genkey -v -keystore DEBUG.keystore
-alias alias_name -keyalg RSA -keysize 2048 -validity 10000
Is my problem with DEBUG.keystore? Should I need to generate another keystore for public release?

I am looking for some help. I'm new to android, and java development. I've got a pretty good handle on the basics, but I'm having an issue figuring out some more advanced operations. I'm working a guitar tuner, which is a stepping stone to a chromatic piano tuner. There is no public API for frequency analysis, so I'm thinking I need to write into code a Fast Fourier Transform, and I'll assume I need to import a different package for this. Once I display the frequency of any given note, I need it to reference it's offset to a pre-measured Mhz. There is alot to write, I'm aware, but my first step is to try to figure out HOW to get the frequency, and display it in the UI.

Here's a snip that successfully reads off, to Eclipse LogCat, the height and width of the .PNG on the SD card:
import android.app.Activity; import android.os.Bundle;
import android.util.Log; import android.graphics.Bitmap;
import android.graphics.BitmapFactory; import android.os.Environment;
//...
Bitmap bmp = BitmapFactory.decodeFile(Environment.getExternalStorageDirectory().getAbsolutePath() + "/sample.png");
int width = bmp.getWidth(); int height = bmp.getHeight();
int[] pix = new int[width * height]; bmp.getPixels(pix, 0, width, 0, 0, width, height);
int R, G, B; for (int y = 0; y < height; y++){ for (int x = 0; x < width; x++) { int index = y * width + x;
R = (pix[index] >> 16) & 0xff; //bitwise shifting G = (pix[index] >> 8) & 0xff; B = pix[index] & 0xff;
// [This is where I'd put it. But I can't get a red line off the editor when I do anything.] } } Log.v(TAG, width + " " + height);
I can't for the life of me use Log.v() to report the value of R or G or B. Everything I'm doing draws a red line under v or something when I try. I've tried toString() and everything.

Is someone from Google able to advise when the Android SDK is likely to include a public API for reading/writing event data to the user's calendar? Searching the forums I see that this is a much desired feature by many developers but I haven't seen any indication as to when (or even if) this need will be addressed.

I find this code useful and want to copy-paste it into my application which is licensed as public domain.
It is the Android blog, they often show useful code snippets. There is no way to contact the author, and the only license info I can see is "©2008 Google Inc. All rights reserved."
Should I:
Stop worrying and just copy-paste?
Reimplement it myself without looking?
Copy-paste and then make it look different?
Any better solution? ...
Is there a rule like "if shorter than 50 lines then no copyright applies" or something?

Under the terms of the Apache Public License, can I use some (graphic) resources in my commercial app?
More specifically, in my (proprietary) Android app, I want to use some graphics from Android. Since Android is licensed under the Apache Public License, I downloaded the source and took the resources I wanted. But I was wondering, if I want to sell this app, or not release the source code, am I allowed? Do I have to put any notices in my app description?

How do you instruct users to report a bug in Android? I'd like to get send detailed instructions to my users to get the most of their bug report. I know there are various apps that send bug reports from the device and I was wondering how other Android developers deal with this.
