I'm building an Android application which uses accelerometer sensor and sends the value of x-axis, y-axis and z-axis to my server, but the problem is when the screen turns off, accelerometer stops working or in other words stops sending data.

How can I fix this? I'm newbie to Android application development.

  • It depends on the hardware you are using (see [list of devices](http://www.saltwebsites.com/2012/android-accelerometers-screen-off)). – user1438038 Jun 26 '15 at 09:14

You should keep CPU on in your device. for do that you have to add this permission in your manifest.

<uses-permission android:name="android.permission.WAKE_LOCK" />

and add this code to your code.

PowerManager powerManager = (PowerManager)getSystemService(POWER_SERVICE);
WakeLock wakeLock = powerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,
    "MyWakelockTag");
wakeLock.acquire();

For more information about this, please refer to this document. Keep the CPU On

You may try using a Service to run the accelerometer in the backround. So when the screen turns off, the accelerometer would still give you current values.
