android - 如何清除 android marshmallow 中的浏览历史记录

Question

我正在清除 android 中的浏览器历史记录。直到 android 5.1.1 即； Lollipop 以下语法工作正常。

Browser.clearHistory(mContextUtility.getContentResolver());

但是，对于 android 6 即；棉花糖它不起作用。那么我该如何解决这个问题，有没有其他方法可以清除浏览器历史记录？

查看 Android 源代码，它看起来对您来说没有前途。请注意，clearHistory 方法不再执行任何操作，因此 canClearHistory 始终返回 false

/**
 * Returns whether there is any history to clear.
 *
 * @param cr   The ContentResolver used to access the database.
 * @return boolean  True if the history can be cleared.
 * @removed
 */
public static final boolean canClearHistory(ContentResolver cr) {
    return false;
}

/**
 *  Delete all entries from the bookmarks/history table which are
 *  not bookmarks.  Also set all visited bookmarks to unvisited.
 *
 *  @param cr   The ContentResolver used to access the database.
 *  @removed
 */
public static final void clearHistory(ContentResolver cr) {
}

以下是 5.1.1 r1 中的相同方法，当它们实际起作用时:

    public static final boolean More ...canClearHistory(ContentResolver cr) {
    Cursor cursor = null;
    boolean ret = false;
    try {
        cursor = cr.query(History.CONTENT_URI,
            new String [] { History._ID, History.VISITS },
            null, null, null);
        ret = cursor.getCount() > 0;
    } catch (IllegalStateException e) {
        Log.e(LOGTAG, "canClearHistory", e);
    } finally {
        if (cursor != null) cursor.close();
    }
    return ret;
}

Delete all entries from the bookmarks/history table which are not bookmarks. Also set all visited bookmarks to unvisited. Requires android.Manifest.permission Parameters: cr The ContentResolver used to access the database.

public static final void More ...clearHistory(ContentResolver cr) {
    deleteHistoryWhere(cr, null);
}
