Android :: Debugging Sample App Snake
Jun 10, 2009
I am using the android 1.5 and have compiled and run the Snake sample application on the Emulator, using Eclipse to launch it.When I try to debug it using the Eclipse environment I get the error:"Launch error: Failed to connect to remote VM. Connection refused."I do have the AndroidManifest.xml debuggable=true set and i went into the emulator and set Dev Tools > Development Settings> and checked "Wait for debugger", and added the snake app to the Debug App.So not sure what else to do to get it to work.I also turned off my firewall just in case too.

I created a new project based on the Wikitionary sample.After tinkering with it so much and screwing it up, I decided to delete the project and start over again.After deleting my project, I find that the Wiktionary sample is no longer available as a starting point.

I am using a gutted version of the Snake Android sample. Pretty much I am using the TileView class verbatim and am only trying to display a few tiles on the screen. Instead of the SnakeView class I am using a GameView class in which I only included the code I thought necessary to display a tile on the screen.
Here is the class
CODE:...............
Now what is happening is that when the updateWalls() method is called, the tiles are placed within the View and comes up like this:
Now when I uncomment out the updateCellularArray() method and comment out the updateWalls() the program force closes and throws a NullPointerException. After some debugging I figured out that when the updateCellular array method is called, the mTileGrid array in the TileView class is not initialized, but it is when updateWalls() is called. I am completely baffled as to why this is happening. It doesn't matter if i replace the for loop with a simple setTile(GREEN_STAR, 3, 3); it still force closes.
Here is the TileView class I am using (again this is the same one in the Snake sample that comes with the Android SDK):
CODE:.......
simplified GameView class
Alright after modifying the updateCellularArray() method to the following:
CODE:........
It finally placed the tile where I wanted it to...
I'm starting to wonder if it has something to do with the RefreshHandler. Possibly when the RedrawHandler's sleep method is called in the update method of the GameView class. I'm not quite sure how it works so I am going to try playing around with it and see what I can come up with.

I just published a free preview of a 3D implementation of the classic snake game. It works smoothly enough on Milestone, please let me know how it works on other phone. You can download it searching for Snake3D.

I load up the app Snake and when it loads, it says, "Pasued: Press Up To Resume." I can't figure it out for the life of me. Then it will read, "Sorry! The application Snake (process com.example.android.snake) has stoped unexpectedly. Please try again.
I try again. Repeat.

I'm trying to determine whether or not my phone is defective, or if this is a current problem with the Cliq.
Of the apps I've downloaded, only a few of them have worked. Of those few that work, some don't work right. Has anyone had problems with these apps crashing on them, or just not working correctly?
- Nice Battery (see description at bottom of: My Ultimate CLIQ settings (so far))
- WeatherBug (kept showing the wrong location, crashed when trying to change location)
- Snake - doesn't work just says its "paused"
- RingDroid - crashes when I select the "Facebook Pop" button
- Layar - screen is rotated 90 degrees at all times
There have been others, but usually I just uninstall them right after discovering it doesn't work right.

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?

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.

I would like to make an android application that opens the device microphone and records same samples, my question is if it is possible to know the bps(bits per second) of the recorded audio file. Also is this possible to do from a file stores on the SD card?

My audio analysis application needs a microphone sample rate of greater than 8000 Hz.At least 11025 Hz is required.It seems that some phones support a higher rate and some are limited to 8000 Hz.Does anyone know what percentage of Android phones will support the higher sample rate?And if I do develop this app, how can a potential customer determine whether or not his particular phone supports the higher sampling rate?

I'm breaking into GUI programming with android, trying to compile and analyze Lunar Lander sample program. The instructions for using Eclipse say to select "Create project from existing source" but that option doesn't exist. If I select File->New->Project I can select "Java project from Existing Ant Buildfile". Using that I've tried selecting various xml files as "Ant Buildfile" but all give me the "The file selected is not a valid Ant buildfile" error.I just want to run GUI sample projects, preferably with Eclipse. Any useful tips will be appreciated.

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?

I downloaded the sdk and added the library to my workspace, then the sample for market licensing. The sample app seems to force close somewhere after/during the instantiation of LicenseChecker. I tried running on the emulator with Google API 8 and on a droid x with froyo and it force closes. The stack shows PerformLaunchActivity as the top item. Both emulator and phone had a registered gmail account. how to get this to work?

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.

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.

I would like to know what I have to do in order to have the Business Card Sample in SDK 3 (android 1.5), because it uses some stuff that does not compile in android 1.5, example: - if (sdkVersion < Build.VERSION_CODES.ECLAIR)... -import android.provider.ContactsContract.Contacts; -import android.provider.ContactsContract.CommonDataKinds.Phone; What is the best way to have the application compiling in eclipse and be able to run in android 2.0 and 1.5?

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?
