When developing Android application, we always need to invoke other system applcation (e.g. contact, phone dialer, camera,etc) In this post, I will summarize some method to invoke different phone and dialing related system activity.
1. Start the phone dialer
Intent intent =new Intent(); intent.setAction("android.intent.action.CALL_BUTTON"); startActivity(intent);OR
Uri uri = Uri.parse("tel:xxxxxx"); Intent intent = new Intent(Intent.ACTION_DIAL, uri); startActivity(intent);2. Go to Dialer Applciation
Intent intent= new Intent("android.intent.action.DIAL"); intent.setClassName("com.android.contacts","com.android.contacts.DialtactsActivity");3. Open Phone Contacts List
Intent intent = new Intent(); intent.setAction(Intent.ACTION_VIEW); intent.setData(Contacts.People.CONTENT_URI); startActivity(intent);4. Pick a Phone Contact
Intent intent = new Intent(); intent.setAction(Intent.ACTION_PICK); intent.setData(Contacts.People.CONTENT_URI); startActivity(intent);5. Edit a phone contact
Intent intent=new Intent(Intent.ACTION_EDIT,Uri.parse("content://com.android.contacts/contacts/"+"1")); startActivity(intent);6. Add a new phone contact
Intent intent = new Intent(Intent.ACTION_INSERT_OR_EDIT); intent.setType("vnd.android.cursor.item/person"); intent.setType("vnd.android.cursor.item/contact"); intent.setType("vnd.android.cursor.item/raw_contact"); intent.putExtra(android.provider.ContactsContract.Intents.Insert.NAME, name); intent.putExtra(android.provider.ContactsContract.Intents.Insert.COMPANY,company); intent.putExtra(android.provider.ContactsContract.Intents.Insert.PHONE, tel); intent.putExtra(android.provider.ContactsContract.Intents.Insert.PHONE_TYPE, 3);7. Invoke send SMS and MMS UI
Intent intent = new Intent(Intent.ACTION_VIEW); intent.setType("vnd.android-dir/mms-sms"); startActivity(intent);
