F-droid source code snippet (2) download module arrangement, f-droid source code
In this article, the download function of F-droid is modified separately and a demo is provided.
It is hoped that it will serve as a reference for the future. You can also download the kids shoes.
In fact, there are two main ideas:

News source: Gu AOGizmodo editor Jason Chen has the opportunity to play with Nexus One by a secret. To sum up, even if it is not an iPhone killer, it is definitely a droid killer. It is very thin and fast, and everything is even better.Since the secret did not let me take pictures, this is not a gorgeous evaluation of "Multi-image cat killing". I just talked about its comparison with droid and iPhone 3gs th

Recently, I want to prepare a project report and try to connect to the remote Radmin server using Radmin view. I want to use the remote control Simulator Interface and project it to the projector for explanation. However, the Radmin server is not free and the old activation fails, you cannot connect to the remote control software that comes with windows. After checking the relevant information, we found a controller: droid VNC server.

Linux uses the locate command to locate a file

FIND command
Many Linux users like to use the find command to find files. For example, they usually like this:
Find/-name 'pattern'
Indeed, the powerful function of find is not only used to find files, but also to locate

First, the method of locating elements
ID: Preferred recognition attribute, the standard recommended for each element of the page set a unique id attribute,
If it is not and it is difficult to find the unique attribute, workaround: (1) Find the development to add the ID or name. If not, the solution can be:1. Find the feature of the button, such as the text of the button is submit;2. Using XPath to locate, you can write://button[@value =
Use gdb to quickly locate the "segment error" and gdb to locate the segment Error
Sometimes, when we operate on an invalid memory in a section of C/C ++ code, the "Segmentation fault (core dumped) "-- segment error.
I think many people will often encounter this problem. This problem is very speechless, just prompts "segment error", and then there is nothing. If we blindly look at the code to find it too p
Locate can position the current cursor on a qualified record. The first parameter of locate is the condition field, and the second parameter is the condition.Value. The third parameter indicates whether the search is case-sensitive and partially matched. You can set multiple conditions for locate as follows:Table1.locate
Locate and z-index, locate z-index
Positioning
Location used to control the element
The positioning keyword is position and position has four values: relative, absolute, static, and fixed. After the element is located, the element has four values available: left, right, top, bottom.
I will use the following examples to demonstrate the absolute location of absolute and relative location of relative.

-A finds all content, not the first file

Syntax of the Whereis command: Whereis [-BMSU] [BMS directory name-f] File name
The options for the Whereis command have the following meanings:
-B locates the executable file.
-M
The following 4 main commands are found under Linux: Which, Whereis, locate, and find.(1) which [-a] cmdname1 cmdname2 ...Command parameters:-n Specifies the length of the file name, which must be greater than or equal to the longest file name in all files.-P is the same as the-n parameter, but the path to the file is included here.-W Specifies the width of the field at the output.-V Display version informationRole:

The difference between this method and the previous two methods is that this method usually searches for more than one element, so it is generally recommended to use the Findelements method together. For example, if we want to find out how many buttons are on the page, we can use the button tagname to
