In the C/C ++ layer of the android 2.3.3 source code, you need to debug the code, But the strange thing is that you can directly add logd ("XXXXXXXX ");, logcat does not display any output. Logi, logv, logw, and loge are ineffective. So I found the solution on the Internet. After several experiments, I finally found the solution. Now I will post the following notes:Step 1: Add local_ldlibs: =-llog to the corresponding MK FileStep 2: add the following

In the PHP login verification time code, the problematic user name and account are stored in the txt text, that is, the password cannot be verified. I have tried to verify the user name separately and I don't know where it is wrong .. $ Logi = file ("users.txt "); $ Size = sizeof ($ Logi ); Foreach ($ Logi as $ Key => $ Val) {$ Data [$ Key] = explode ("|", $

When php data is written to txt, the following error occurs: filename='users.txt '; $ Name = trim ($ _ POST ["name"]); $ Passwd = trim ($ _ POST ["pass"]); $ Str = $ username.

"\ r \ n "); Fclose ($ handle ); Return 1; } Else return 0; } Record the name and password in txt in the format of mmm | 123456 Yyy | 123456 My code is as abo

In Android, Java code outputs log information through Android. util. log. The same local C/C ++ code also provides more interfaces. Android directly goes to the header file (System/CORE/include/cutils/log. h) defines some log Output Macros, which are better than Android. util. log provides more log output interfaces. Therefore, you can use these macros to output the same logs as those in Java code. Macro logd (), LogE (), Logi (), logv (), logw (), an

Output support on the android C/C ++ layer. Recently, I have been studying the C/C ++ layer of Android 2.3.3 source code. I need to debug the code, but it is strange that I directly add logd ("XXXXXXXX ");, logcat does not display any output.

environment: the Android platform provides a make-based compilation system, which can be used to compile the correct Android. mk file for the App. The environment needs to get a complete copy of the source code from the official website through git and successful compilation, for more details, see: http://source.android.com/index.html No matter which of the above two methods you choose, you must write your own Android. mk file. For how to write this file, see the relevant documentation. JNI com

http://blog.csdn.net/pkigavin/article/details/8583537Recently, in the study of the Android 2.3.3 Source code c/S layer, you need to do some debugging of the code, but strangely, directly add logd ("XXXXXXXX"), use logcat but do not see any output, switch to Logi, LOGV, LOGW, Loge also has no effect. So on the Internet to find solutions, after several trials, finally found, and now posted to the following memo:First step: add: local_ldlibs: =-llog in t

With Python's logging, every time you write a log, you make a small module to make the log more convenient.The code is as follows log.py Import Logging, Logging.handlersImport ConfigImport Inspect FORMAT = '% (asctime) s-% (name) s-% (levelname) s-% (message) s 'Log_level = logging. DEBUGLogger = {}Handler = Logging.handlers.RotatingFileHandler (Config. Path_log_file,MaxBytes = 1048576 * 2, # 2MBBackupcount = 5,)Handler.setformatter (logging.

Thunderbolt and USB 3.0 interface, data transmission performance is very stable. A good input device Input device performance is also the key to improve office efficiency, you need to choose a good ergonomic design, feel comfortable keyboard or mouse, but also give priority to wireless models, because it can effectively avoid cable winding, reduce efficiency. As for the form of wireless transmission, usually using a 2.4GHZ USB receiver device compared to Bluetooth has a more stable performanc

purchase UVC cameras. UVC is an open standard with a well maintained drive, which is part of the kernel code. After inserting the camera, you can work without having to compile or install additional drivers. NON-UVC cameras usually does not work better than the UVC cameras, the former driver does not follow the general protocol, the need for each camera to make separate processing, which often requires a reverse engineering exploration process.To determine if a camera belongs to the UVC specifi
