我想在最近几(5或10)分钟内捕获Android手机中所有浏览器的浏览历史记录。我正在使用的代码是
Calendar ci = Calendar.getInstance();
String enddate = "" + ci.get(Calendar.YEAR) + "-"
+ (ci.get(Calendar.MONTH) + 1) + "-"
+ ci.get(Calendar.DAY_OF_MONTH) + " " + ci.get(Calendar.HOUR)
+ ":" + ci.get(Calendar.MINUTE) + ":" + ci.get(Calendar.SECOND);
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
ci = Calendar.getInstance();
ci.add(Calendar.MINUTE, -5);
String startdate = "" + ci.get(Calendar.YEAR) + "-"
+ (ci.get(Calendar.MONTH) + 1) + "-"
+ ci.get(Calendar.DAY_OF_MONTH) + " " + ci.get(Calendar.HOUR)
+ ":" + ci.get(Calendar.MINUTE) + ":" + ci.get(Calendar.SECOND);
long startdates = 0;
long enddates = 0;
try {
Date endDate = (Date) new SimpleDateFormat("yyyy-MM-dd HH:mm:ss")
.parse(enddate);
Date startDate = (Date) new SimpleDateFormat("yyyy-MM-dd HH:mm:ss")
.parse(startdate);
System.out.println("End date=" + endDate.getTime());
startdates = startDate.getTime();
enddates = endDate.getTime();
} catch (ParseException e) {
e.printStackTrace();
}
String[] proj = new String[] {
Browser.BookmarkColumns.TITLE, Browser.BookmarkColumns.URL,
Browser.BookmarkColumns.DATE
};
Uri uriCustom = Uri
.parse("content://com.android.chrome.browser/bookmarks");
// 0 = history, 1 = bookmark
String sel = Browser.BookmarkColumns.BOOKMARK + " = 0" + " AND "
+ Browser.BookmarkColumns.DATE + " BETWEEN ? AND ?";
Cursor mCur = getContentResolver().query(uriCustom, proj, sel,
new String[] {
"" + startdates, "" + enddates
}, null);
mCur.moveToFirst();
JSONObject obj;
JSONArray jarray = new JSONArray();
String title = "";
String burl = "";
String date_time = "";
if (mCur.moveToFirst() && mCur.getCount() > 0) {
while (mCur.isAfterLast() == false) {
title = mCur.getString(mCur
.getColumnIndex(Browser.BookmarkColumns.TITLE));
burl = mCur.getString(mCur
.getColumnIndex(Browser.BookmarkColumns.URL));
date_time = mCur.getString(mCur
.getColumnIndex(Browser.BookmarkColumns.DATE));
try {
obj = new JSONObject();
obj.put("title", title);
obj.put("url", burl);
obj.put("date", date_time);
jarray.put(obj);
} catch (Exception e)
{
e.printStackTrace();
}
mCur.moveToNext();
System.out.println(title);
}
}
如果我更改
,我可以从Chrome浏览器获取整个浏览历史记录String sel = Browser.BookmarkColumns.BOOKMARK + " = 0" +" AND " +Browser.BookmarkColumns.DATE+ " BETWEEN ? AND ?"; // 0 = history, 1 = bookmark
到
String sel = Browser.BookmarkColumns.BOOKMARK; // 0 = history, 1 = bookmark
但是我需要最近几分钟的浏览历史来更新数据库。我是android开发的新手。任何帮助将不胜感激。提前谢谢..
答案 0 :(得分:1)
您无法从所有浏览器获取历史记录,您只需获取默认浏览器的历史记录(随手机附带)。
其他浏览器使用私有作用域来保存此信息,没有API。
准备填充" ?" on sel 需要是时间戳(长),而不是yyyy / mm / dd格式。
只是做:
final Calendar ci = Calendar.getInstance();
final long endDate = ci.getTimeInMillis();
ci.add(Calendar.MINUTE, -5);
final long startDate = ci.getTimeInMillis();
final String[] paramsSel = new String[] { String.valueOf(startDate), String.valueOf(endDate) };
注意:使用String.valueOf将任何类强制转换为String,不要使用("" +)可能是错误的,例如当转换为float时,分隔符将不会被定位(反而。或反之亦然)。
希望它有效。
