android usb debugging

when it comes to mobile development, we often use Chrome's own simulator to simulate a variety of mobile devices. But simulation is simulation after all, when the development is complete, using the real machine to access the page problems when debugging?Here is a debugging method for Android1.Install the latest version of Chrome on both PC and Android phones2.Con

When debugging a program, the output of the parameter is helpful for us to understand whether the entire program operates according to our own logic. Java programs under the Android platform have many ways to output information in the console: 1. System.out.println ("... "); 2. Android.util.Log ("... "); Now, we're going to separate these two inputs to see how we can get the content out of our relations

Logcat Dump a system message log. These messages include the stack trace when the simulator throws an error. Android log A logging class used to write messages to log files on the simulator.

D () (Debug), log. I () (Information), log. W () (warning) or log. E () (error),

If you have the source code, you can do it easily, but you do not have the source code to tune bugs or reverse the code. This article lists some binary-level analysis and debugging tools and methods in Android. Logcat: In most cases, no direct answer is found in logcat, but the direction for further analysis is often obtained. By default, logcat outputs all of them together, making it easier to read the Ou

Recently, because you want to debug your code on another Android device, check its log on your native PC. Two machines away from the relatively far, can not be directly connected with the USB, so find a lot of information on the Internet, the most find using the ADB Connect method to solve the problem. The resolution process is as follows:1, verify that the native PC does not have any ADB device connections

On the internet for a long time, the information on the internet is basically said to use a foreigner to write the library, but in fact the case of this library is not directly used (because of the permissions problem), not suitable for learning.Later, it was discovered that the library was re-encapsulated, and there are source code and Chinese tutorials:http://blog.csdn.net/andrexpert/article/details/78324181Https://github.com/jiangdongguo/AndroidUSBCameraAnother way of thinking is to use OPENC

Recently in the Debug msm8996 board, because the motherboard and LCD sub-board has not come back, so the first back of the core board is a headless Android Device. The core board has independent power supply, in addition to USB type-c, FAN, HDMI, TF card and key hardware modules, are now tuned, the effect as shown.During the debugging process,
