I am developing a small application for learning purpose which will move image when accelerometer readings change. I want a mapping of accelerometer values to screen coordinates. I am using trial and error method rite now. But it seems that it will not help. Is there any algorithm??

I am developing a game. In which the user controls movement using the accelerometer. Sounds effects can also be enabled. However when laying the phone flat down and playing the game without the accelerometer gives nice 0,0,0 values. However when play WITH SOUNDS on, i get a buch of weird values: while the phone is NOT moving.
This is really a big bug that makes life hard for Game Developers. I tried to take an avarge of the last 5 values from the sensor.. but this is not enough.. The harder the sounds plays: the higher the weird sensor values. When using the headphones: almost no weird values. Seems that sounds interferes with the accelerometer sensor.
my problem is this, i have my main class and a second class that displays the values of the accelerometer on a textview.. however if i call my accelerometer class this is what happens, my application starts with no problems however no buttons work from my main class.. it seems to me that the accelerometer class runs above my main class thats why i have this problem.. what i did is i created a new activity on my manifest and called my accelerometer class from my main class using->
Intent i = new Intent(this, AccelerometerClass.class);
startActivity(i);
Maybe there is a way to just take the values from the accelerometer class,wihout calling the class itself ???? what i mean is take the x,y,z(int) values from accelerometer class and set them on a text from the main class..
i'm created an application where it consists of 3d rotating cube I want to move the cube with respect to the drag on the screen.In the on touch Listener I'm able to get the x,y coordinates but i don Know how to make those coordinates to map to 3d space.
View 3 Replies View RelatedI've been trying to write a little application that recognizes custom events in Android: you hold your finger over a TextView for a certain length of time, and it changes color.I'm using the MotionEvent coordinates and checking if they are within the bounds of a particular TextView, which is within a table.I am just attaching the onTouch listener to the table within the activity.But I get weird errors: the coordinates seem to be off by one view (i.e. if I touch the view below the view above reacts); or sometimes one will react, and the other will not. Any idea what might be going on?

View 2 Replies View RelatedI am developing a game in android and i want to capture screen coordinates of a view(ImageView) which is embedded in frame.
Hierarchy is <LinearLayout android android:layout_height="fill_parent" android:layout_width="fill_parent" > <RelativeLayout android:layout_height=fill_parent" android:layout_width="fill_parent" > <FrameLayout android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/frame14"></ FrameLayout> </RelativeLayout> </LinearLayout>
At run time i am attaching two image views for frame layout.I wanted to capture screen coordinates of frame layout.But Couldnt do it.if i say
(FrameLayout) f=(FrameLayout)findViewById(R.id.frame14); int[] loc = new int[2]; f.getLocationOnScreen(loc); System.out.println(loc[0]); System.out.println(loc[1]);
I get Null Pointer Exception for getLocationOnScreen() method.
If I try to get f.getLeft() and f.getRight() they return as 0 coordinates.
Can anyone please tell me how to find location on screen of a view.
Currently it seems that locking the screen automatically turns off the accelerometer. I looked around for quite a while and didnt find any solution for that. Is that intentional? It would be really helpful to know if this is how it is or if I just didnt find the solution for that so far.thank you for any help on that (and as I said, even "doesnt work right now/on purpose/.
View 5 Replies View RelatedAs I understand it, there seems to have been a change in the OS that prevents the accelerometer from running when the screen turns off and the phone CPU goes into its power saving state.Can this be confirmed?I have gotten around this by using a wake lock, but this is a much less than ideal solution as it drains a lot of battery.If the accelerometer was disabled in low power mode to save the battery, it may very well have the opposite effect in many cases, such as mine.A partial wake lock seems to be required to keep it running, which is obviously much worse than if just the accelerometer were running without the need for the wake lock.Are there any other workarounds anyone knows of to getting accelerometer values while the phone is in low power mode?Also, are there any plans to change this in future versions of the OS?If there are no plans to change this, I would definitely like to petition for this to be changed.

I didn't found any way how to detect coordinates of the touch on RemoteViews.Is anybody aware of some trick how to detect it. Only idea I have is create layout with grid of transparent buttons, put by widget's bitmap as background of such a layout and to every button set PendingIntent.
View 6 Replies View RelatedThere are some shortcoming for system's rotate screen function:
1. It is too sensitive to result in many unwanted rotating actions.
2. Accelerometer consumed power greatly. I want disable it and control screen orientation by my own program. Is it possible?
If it could turn to the right as opposed to the left, typing on the landscape keyboard would be much easier. The botton of the phone would not get in the way. Just wondering.
View 1 Replies View RelatedIt seems no matter what I put my settings to, the home screen always has to change orientation when I rotate my phone sideways. This is quite an annoyance. I just want the home screen to be in portrait at all times (unless I open my keyboard). I'm currently on Smoked Glas 5.0.1.

I tried formatting cache but it did not work. the only workaroud is to open the phone, remove battery and restart again. I could not get any solution except the battery removal one.
View 4 Replies View RelatedI need to pass data's (String) from one screen to another screen. At the time of button click i need to pass values from first screen to the next screen.
View 3 Replies View RelatedHow do you set/pass values from one screen (activity) to another? What I have in the R.layout.main view labeled Calculator contains the code for doing calculations. The main.xml contains the layout (view) of the main screen. I have created an options menu which has another screen which shows you setup (R.layout.setup). The dialogsetup.xml contains the layout (view) for it.
When you press the menu button, you get the options menu. If you select "Setup", then it will display the setup screen. Now what I need to do is take the values from the setup screen (radio button and text values) and place them in the main screen so that when you exit the setup screen and go back to the main screen, you can take those values and use them in your main code.
How can I quickly access the screen resolution (width, height) as integer values? I've tried this one, but it always shows zero on my emulator:
DisplayMetrics dm = new DisplayMetrics();
int width = dm.widthPixels / 2;
In my case I want to dynamically create a table with tableRows, each containing two cols. This cols all shall fill half of the screen in width.
I want to ask where does the defaults values of memory min-free values of a Rom reside? I mean what file I would have to edit to edit those values?

View 3 Replies View RelatedI am using a PreferenceActivity to let the user set some values. I am feeding it the xml file with the defined preferences.
I have set all the android:defaultValue="" for them.
When I start my application, I need the preferences, or if they are not set yet manually, I want the default values:
CODE:.................
However, when android:defaultValue="true" I still get false. So, it looks like the defaultValues set in the XML are not used anywhere but when initializing the preferences-screen.
I don't want to hardcode the default values in the getBoolean() method. So, is there a way get the default-values with only defining these in 1 place?
Is there a way I can see my phone's raw GPS coordinates, i.e. decimal lat/long? Is it built-in, or is there "an app for that" ? I have an Eris Droid.
View 4 Replies View RelatedCan GPS on a phone, such as iPhone or Android determine your Z coordinates? I know it certainly has to be able to determine X and Y, well longitude, latitude that is, but what about the Z coordinates? Can it determine your height, and can I obtain height relative to ground?
View 3 Replies View RelatedI want to know if there is a way to be able to get the touch coordinates in an app. I know of the commands getRawX(),getRawY(),getX(),getY().

I'm designing a game for Android and I would like to use the accelerometer for some aspects of control. Has anyone come across a tutorial or example for something like this?
View 1 Replies View RelatedMy accelerometer is not reading the angle of the phone right. When I play Teeter I have to keep the phone on a sharpe angle to keep the ball still, and I feel I have to rotate it extra to go into landscape mode. Now the question is... how do I readjust the accelerometer?

I've seen the Open Intents applications, but I'd rather use the raw Android API, at least until I understand it a little better. I'm surprised at the lack of documentation.
I want to know how to calculate the accelerometer movement.When i place the mobile horizontally in idle state and similarly when i place the mobile in hands,So there accelerometer value change when it is place horizontally or while it is in hand vertically.How To Identify them,Any Sample Codes will be useful.
