Hello everyone,
I am quite new to Android and I found one issue (at least ,it's a problem
for my app..) with the CallLog database and dying battery.
If I'm in a outgoing call and battery drops down - the phone is turned off
and when is up again in the CallLog I can see the last number i have been
talking to,the date when we start but unfortunately - the duration is 0,no
matter how much time we spent on that call.
First ,could you confirm my observations ?Is it the same on other versions
(tested on 2.2...)?
Second ,could you propose me a solution - I do not want to miss that
duration,it's very important for me.
I have some ideas:
1.Add in SharedPreferences flag - when an OutGoingCall is detected
from my BroadcastReceiver it's state is "Started",when hangup is detected -
change the state to "Disconnected"(Started state would be better to be set
when the other part answered to my call,but I couldn't find a way to detect
this moment)
2.Detect Batery_Low under some percentage (5% for instance) and if the flag
says we are in call - start writing in SharedPreferences value of the
duration on every 2 seconds,so I will have an 2 seconds tolerance at the
end.The duration should be taken from
com.android.internal.telephony.Connection.getDurationMilis(); using
reflection..Returns the number of milliseconds the call has been connected,
or 0 if the call has never connected. If the call is still connected, then
returns the elapsed time since connect.
I am not sure it will work,right now I saw :
public static final
String<http://developer.android.com/reference/java/lang/String.html>
ACTION_SHUTDOWN
<http://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels>
Broadcast Action: Device is shutting down. This is broadcast when the
device is being shut down (completely turned off, not sleeping). Once the
broadcast is complete, the final shutdown will proceed and all unsaved data
lost. Apps will not normally need to handle this, since the foreground
activity will be paused as well.
What do you think -can I use this and to try to end the call - again using
reflection in order to provide to the OS some resources to finish updating
the CallLog?Isn't it something that the Android do in this case,normally?
Thank you in advance for your feedbacks.
