Question

I have just started with phoneGap and Android. Built basic samples.

I would like to know, if there is an API to get the call logs. I wish to create a grid showing:

• Number of missed calls over a period of time
• Number of received calls
• Number of calls made
• Total time of the received calls and calls made

Thanks in advance.

Answer 1

I did a bit of research and has successfully built a PhoneGap plugin which would fetch the CallLog from android.provider.CallLog.

This returns an JSON { Rows: [] } where Rows is an 2 dimensional array of call records containing the following fields (as Array) in the following order :

• Date (as UNIX Time stamp)
• Number,
• Type (1- incoming, 2- outgoing, 3- missed)
• Duration (in seconds)
• New
• Cached Name
• Cached number type
• Cached number label

Details are in http://developer.android.com/reference/android/provider/CallLog.Calls.html

I have also made a small sample using this plugin which would show total number of outgoing calls, missed calls and incoming calls and plot them in a Pie chart. The sample is using FusionCharts’ Pie chart.

You can download a beta try-out .apk from :

http://www.sudipto.net/download/android/apps/CallLog/beta/CallChart.apk.zip

(using JavaScript SVG charts that works in Android version 3 or above)

Here is the source-code zip for you to delve into:

Here is my complete code:

                try {
                        switch (getActionItem(actionName))
