you can’t do without rooting your phone or
becoming a vendor, like say Motorola.

Calendar Example
• Once a calendar is connected to the device
• You can use the following example from
google to read/write to the calendar
– Uses the Calendar Provider
• http://developer.android.com/guide/topics/pr
oviders/calendar-provider.html
Contacts Example
• Same with contacts
• http://developer.android.com/guide/topics/pr
oviders/contacts-provider.html
User Dictionary
• Android use the user dictionary for the
example in the “content provider basics”
example.
• http://developer.android.com/guide/topics/pr
oviders/content-provider-basics.html
AccountManager
• Provides a centralized registry of the user
online accounts
– Example: Facebook, dropbox, Evernote, etc…
– There are some examples of how to use and
create your “account” for your online service.

Incoming/outgoing phone calls
• Detectcalls app in PremissionDemo.zip
• Uses: PROCESS_OUTGOING_CALLS and
READ_PHONE_STATE
• The example uses two Broadcast Receivers
– You can do it in one, but split for the example.
– Able to get the phone number and the information.
– http://androidlabs.org/short-experiments/broadcastreceivers/process-outgoing-calls/
• This example also shows you have to change the incoming phone
number!
– http://code.google.com/p/krvarma-androidsamples/source/browse/trunk/DetectCalls/?r=37
Incoming/outgoing phone calls (2)
• You can block outgoing phone calls
– You use: setResultData(null);
– That will stop the outbound call!
• http://stackoverflow.com/questions/599443/hang-upoutgoing-call-in-android
– You can not drop/ignore incoming calls thought.
Requires the MODIFY_PHONE_STATE permission,
which is a system level permission.

• http://androidsourcecode.blogspot.in/2010/10/blockingincoming-call-android.html
Task lists
• RunningApp in the Demo shows how to get the
Running Applications.
– It’s pretty simple.
– Get the ActivityManager from the service
– You can get RunningServices, RunningAppProcesses,
RunningTasks, and RecentTasks.
• My example will list the package name for each one in
the list.
• Reference:
http://stackoverflow.com/questions/5446565/androidhow-do-i-check-if-activity-is-running
Reorder Tasks(2)
• While facebook, use the reorder_tasks
permission, I can’t find a single example for it.
• What I did find an interesting article on how
all the activities (tasks) work on the back to
front of the stack.
– And managing how your activities are launched
with the launch modes.
WallPaper
• Get the intance of the wallpaper manager.
• Then use setBitmap, setResource, or
setStream methods to change the wallpaper
• The example (setwallpaper) is very simple and
uses a wallpaper in the resource directory.
Read/Write profile
• In JellyBean (Api 14+) you can have several
user profiles.
– And we have methods to read and write these
profiles.
– It’s handled through the Contracts, so you will
need at least READ_CONTACTS permission as well
and READ_PROFILE and WRITE_PROFILE
Read/Write profile
• The profile is handled with a ContentProvider.
• So to get the entire profile (I think every
profile) you need the following query:
Cursor c = getContentResolver().query(
ContactsContract.Profile.CONTENT_URI, null,
null, null, null);
Read profile example
• The readPofile project reads all the profiles on
the device and displays the information to the
screen, using the query before.
• Remember the device must be 14+ to use this
one.
• My example is heavy modified, but based on
