Apps Can not get acceleration at screen OFF

[miyazaki99]

I make Pedometer app that run in the background.
But I can not get acceleration at Screen OFF in GalaxyS3.
I wanna get acceleration even if device is Screen off.

I tried the following wakelock

　・PARTIAL_WAKE_LOCK
　・SCREEN_DIM_WAKE_LOCK
　・SCREEN_BRIGHT_WAKE_LOCK
　・FULL_WAKE_LOCK

But,If user turn OFF the screen,the CPU of the device stops.
If, you know when I come Action, Could you tell us.

Ah, gotcha..so you are developing an app and are having difficulty trying to make it run whilst the devices' screen shuts off and goes to sleep. Correct?

i have a feeling i heard something in a podcast the other night about user apps not being able to access the accelerometer while the display is off (on stock samsung anyway). They were talking about how samsung's s-health app is ok because it can use the accelerometer as a pedometer in the background.
I could be wrong here though :beer:

Yes,that's right.

I don't know why wakelock doesn't work.
Anyother devices work wakelock(PARTIAL_WAKE_LOCK)

Thank you, funkylogik.

I think samsung's s-health app that use their Private API.
If it is fact,I can't get acceleration at screen OFF.

But,This app run at Screen Off.I can't understand this mechanism

This sounds more like a question for a developer or those who may know more than I.

Welcome to our AndroidForums, miyazaki99.

Not sure what issues you might be having, but I'll try to give you a few tips that might help.

Re. the Runtastic Pedometer app cited above, it uses these permissions:

package: com.runtastic.android.pedometer.lite
uses-permission: android.permission.ACCESS_COARSE_LOCATION
uses-permission: android.permission.INTERNET
uses-permission: android.permission.WRITE_EXTERNAL_STORAGE
uses-permission: com.android.vending.CHECK_LICENSE
uses-permission: android.permission.ACCESS_NETWORK_STATE
uses-permission: android.permission.READ_PHONE_STATE
uses-permission: android.permission.WAKE_LOCK

and the Play Market's Permissions tab does show this at the bottom which is certainly due to use of the above WAKE_LOCK:

AFFECTS BATTERY

PREVENT DEVICE FROM SLEEPING
Allows the app to prevent the device from going to sleep.

Here's simple code that I've used before (it's been a long while, though ):

[HIGH] // wakelock-related variables
//
static Boolean wakelock_acquired = false;
public static PowerManager powermanager = null;
public static PowerManager.WakeLock wakelock = null;

// initialize our powermanager and wakelock variables
//
powermanager = (PowerManager) getSystemService(Context.POWER_SERVICE);
wakelock = powermanager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "YourAppName");

wakelock.acquire(); // keep the CPU alive![/HIGH]

Also, stackoverflow.com is a great resource for your Android questions (these are the first three results of a Google search using "android wakelock tutorial"):

How to get an Android WakeLock to work? - Stack Overflow

How can I keep my Android service running when the screen is turned off? - Stack Overflow

and this site is awesome, too:

Using Android Wakelock – Staying up all night long | vogella blog

Using the Log method to record some debugging messages I find is always helpful to record events in key places and then view them via a logcat or from the Eclipse IDE's logcat viewer.

Best of luck and I hope this helps!
