wakelock not working properly

Question

I wrote a program where I have two services in one I collect data from accelerometer and in the second one i collect data from gyroscope. I am using wake_lock in both. Problem is that it is working only when I run it from android studio , then when I run it second time from phone it didn't work and stop collecting data when i lock the phone. Can you help me where is the problem ? THx

Answer 1

i think you should use PARTIAL_WAKELOCK

change this:

wakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK, "funguj");

to this:

wakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "funguj") ;

this keeps the cpu on after you pressed the lock button link

do you have set the permission in android manifest?

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