Android :: LVL Sample Application

Aug 2, 2010

I've followed the instructions for loading the sample LVL application and it loads up with a bunch of errors. Anywhere that a "R.layout.main" or "R.*" request is made it says R cannot be resolved. It suggests importing Android.R but if I do that then it says it can't find any of the files, including the R.layout.main file which is definitely there.What gives? I have had several problems with sample applications so far, am I doing something wrong? You'd think that all you have to do is import it from existing source and it should work.

Android :: Sample Code / Application Stopped Unexpectedly

Nov 8, 2009

The code seems no problem when I run it, but it stop unexpectedly in the emulator. I read some answer in the forum, It has to look at the logcat to see about the exception handler. But I do not really understand the logcat output. Please, developers, help me!. Below are the coding and my logcat output.

package com.example.testing; import android.app.Activity; import android.media.MediaPlayer; import android.os.Bundle; import android.util.Log; import android.widget.TextView; import android.widget.Toast; import com.example.testing.R;

tx = new TextView(this);setContentView(tx);Bundle extras = getIntent().getExtras()
playAudio(extras.getInt(MEDIA));}

mMediaPlayer.setDataSource(path);
mMediaPlayer.prepare();
mMediaPlayer.start();
break;case RESOURCES_AUDIO:/**

Android :: Change Number Of Thumbnails Seen In Sample Home Application?

Mar 16, 2010

I am working with the sample Home application project on http://developer.android.com/resources/samples/Home/index.html

I've added another value to the THUMBS_IDS and IMAGE_IDS Integer arrays in the Wallpaper class for a total of four wallpaper options.

When I run the application with Device API version 7, Skin: HVGA, hw.lcd.density: 160, in portrait layout, the fourth wallpaper option is not shown.

I need to use the directional keys in the emulator to see the 4th wallpaper option, because the first option is centered.

I have modified only the wallpaper.xml file with a variety of android:layout_* options with no success at this point.

How do I show all four of my wallpaper options?

Android :: IME Sample In SDK

I want to create a new on-screen-keyboard, and I thought that a good start point will be to see how the SoftKeyboard sample in the SDK (under the SDK folder: android-sdk-windows-1.5_r1platforms android-1.5samplesSoftKeyboard) works. But it doesn't! I run it in Eclipse. So, it compile, then the emulator starts, and under "Settings->Locale&text" I see the new keyboard. But it does not show up when I click on a textbox. Only the regular on- screen keyboard appears. Am I missing something?

Android :: Getting Error Using ContactManager Sample / Fix This?

Jun 2, 2010

I have created some contacts data in the emulator. When I run the ContactManager sample app downloaded from the Android site, I get an error. Specifically, when trying to add a Contact through the app, I get a NullPointerException.

I think it is because the "Target Accounts" spinner on the scree is not getting populated, and hence I cannot select a Target Account before adding a contact.

Has anyone run across this problem or has any clues on how to fix this?

Android :: Varied Accelerometer Sample Rate

Jul 9, 2009

Has anyone been able to get the accelerometer on the G1 to sample consistently for long periods of time? We been doing some testing of the G1 accelerometer on Android, and wanted to see if others have gotten the same result.Our test uses a partial wake lock to keep the CPU alive.It stores the xyz values and time to local storage and then writes them to a file on the SD card once a second.The code below produces a csv file.The xyz values we're getting are within the expected range, but the sample rate of the accelerometer varies greatly.To determine that using the file produced, for each sample, we found the difference between the samples timestamp (taken from the SensorEvent) and the timestamp from the previous sample.The test results showed the time between samples ranging from 30 milliseconds up to 4.6 second spikes.We're interested to know if other people are seeing similar behavior from their phones.If you have the time and means.

Android :: Voice Recognition In Sample API Not Working

Not sure what I am missing (using emulator not phone). I was trying to get the speech api working, however it gives me the error: No Activity found to handle Intent { action=android.speech.action.RECOGNIZE_SPEECH (has extras).

So then I tried running the 1.5 r1 sample code (api) and tried the speech sample there, but it also isn't running. Indicating I was missing an app or component. So what is the missing link? It seems as if the actual emulator doesn't come with some default apps which make the voice recognition possible.

Android :: App That Scans Barcode Off A CD / Sample Album?

Jan 3, 2010

Seems like a great idea for an app. You're at a store like Walmart, and you see a CD that catches your eye. You scan the barcode, and can now click on each track to sample each song right from your Android phone. Lets you know whether or not you want to buy it. Some stores already have something similar, but not all stores have it and not all stores have it for all CD's. I'd like to do it from my own phone anyway, than to put on the greasy lice infested headphones at the store anyway.

Yes, I know I can just buy the songs on itunes or Amazon, but sometimes I like to have the actual CD, and the mood strikes me to buy a physical disk now. Does this exist?
