Recently, I have been studying the implementation of GIF on Android and have some experiences. Now I want to share it with you. At first, I saw the implementation of GIF on my mobile phone. It was an application of GIF kuaishou on the iPhone. I felt pretty good and wanted to implement it on Android. I checked it later. In the past, there was also a GIF kuaishou on Android, And the next one provided a good experience. Decompilation (sorry, you should use obfuscated compilation ). JavaAlgorithmB

1. Problem description: a Scheduled Update Project written in Python under the Django framework, which is tested in windows and tested in Linux, reports the following error: ASCII codec can't decode byte 0xe8 in position 0: ordinal not in range (128) 2. Cause Analysis: character problems. Character problems can easily occur when switching from a Windows system to a Linux system. 3. Solution: Add the following three lines to the problem page: Impor

This essay introduces a commonly used BASE64 exception condition that is not easily found when encoding and decoding URIs.Android uses NANOHTTPD as an HTTP server to provide HTTP data stream transmission to the application, using BASE64 to encode a resource, as follows (debug):Resources:/storage/emulated/0/movies/the Mountain.mp4Base64 after encoding: l3n0b3jhz2uvzw11bgf0zwqvmc9nb3zpzxmvvghlie1vdw50ywlulm1wna==At this point the link to this resource is this: http://xxxxxxxxxxxx/L3N0b3JhZ2UvZW11b

The path in Windows is a backslash \, but the backslash \ has the meaning of escape characters in Python, so when writing Windows file paths in a py file, pay special attention to the use of backslashes.Here are three ways to solve the problem: 1 way one: escaped by 2 3 c:\\users\xxx\desktop\a.txt " Span style= "COLOR: #008080" > 4 5 Mode two: explicitly declaring a string without escaping 6 7 r" c:\users\xxx\desktop\a.txt " 8 9 Method Three: Use the path of Linux 1

Learning python, using os.path.getsize (' c:\user_weblogic.dmp ') to get the size of a file, try a few, can produce results. As a result, when you try this file, you always find an error: SyntaxError: (Unicode error) ' Unicodeescape ' codec can ' t decode bytes in position 2-3: truncated \uxxxx escape The same is true for a awrrpt.html file name .... It was due to the existence of \u, which led to the escape of Python, which could not find the cor
