Android鎖屏未讀短信，未接電話
由於鎖屏在framework中，所以不需要添加相應的權限，如果是第三方app需要實現類似的功能，就必須聲明權限。這也就是為什麼Android手機的用戶隱私很容易被泄漏的原因。短信存放地方：/data/data/com.android.provider/telephony/databases/telphony.db
通話記錄存放地方：/data/data/com.android.provider/telephony/databases/mmssms.db
未讀短信數量獲取方法：
由於短消息有短信和彩信2中，所以需要查詢2次。sms是短信，mms是彩信。
Cursor curMms = null;
int count = 0;
try {
String sql = Mms.READ + " = 0 and " + Mms.MESSAGE_TYPE + " != " + PduHeaders.MESSAGE_TYPE_DELIVERY_IND//
+ " and " + Mms.MESSAGE_TYPE + " != " + PduHeaders.MESSAGE_TYPE_READ_ORIG_IND;
curMms = contentResolver.query(Uri.parse("content://mms/inbox"), null, sql, null, null);
count = curMms.getCount();
} catch (Exception e) {
XLog.e(e.toString());
e.printStackTrace();
} finally {
if (null != curMms) {
curMms.close();
}
}
Cursor curSms = null;
try {
curSms = contentResolver.query(Uri.parse("content://sms"), null, "type = 1 and read = 0", null, null);
count += curSms.getCount();
} catch (Exception e) {
e.printStackTrace();
XLog.e(e.toString());
} finally {
if (null != curSms) {
curSms.close();
}
}
未接電話數量獲取方法：
未接電話需要在通話記錄中查詢，通話記錄的類型分為三種：去電，來電，未接。
Uri uri = Calls.CONTENT_URI;
String[] projects = new String[] { Calls._ID, Calls.NEW, Calls.DATE };
String selections = Calls.NEW + " = ? AND " + Calls.TYPE + " = ? AND " + Calls.IS_READ + " = ? ";
String[] args = { "1", Integer.toString(Calls.MISSED_TYPE), Integer.toString(0) };
Cursor cursor = contentResolver.query(uri, projects, selections, args, null);
int count = 0;
if (cursor != null) {
try {
count = cursor.getCount();
} finally {
cursor.close();
}
}
