android call log symbols

There are usually two ways to develop Android applications: ndk and eclipse, or add them directly in the android SDK. This section describes how to add an application in the android SDK environment. It involves JNI and Java calls to JNI. The JNI code file is C ++. The first step is to establish the JNI-Layer Code. Note that the JNI code path has a great relatio

First of all, we found that most of the Android smartphones we use now have the power button to hang up when you're on the phone, usually in the setup. I mainly in the original source code to add this function, mainly for learning .... First look at a picture: See that press the power button to hang up the phone, that is what I added, originally source code is not this column ... probably thinking： First I add this checkboxpreference, and then I s

Find out the call stack of the program trace can know who called this interface, but also quickly learn the process of invoking the program, very practical. However, it is important to note that it cannot be used in formal code, only for debugging purposes, and this very expensive source can also cause log flooding.Here's how to print out the program call Trace i

I recently contacted the Android platform JNI call and found that the network information has not provided a more detailed introduction from the principle to the specific implementation. Therefore, I have referenced some materials and added some experiences based on the project development: Origin of JNIJNI is the abbreviation of Java Native Interface. It allows Java code to interact with code written in ot

In common C/C ++ code, you can respond to the segmentation fault error caused by improper memory operations, that is, the signal SIGSEGV (11. You only need to set the handler of SIGSEGV in the program, call the backtrace of libc, and output the corresponding stack information. The problem will soon be found. However, in Android, bionic does not provide similar functions, and the

[Android Notes] crash log collection and Android crash logs After the application was released, some people reported that a crash occurred, but I was unable to locate the problem because I couldn't get the log. Later we found that we should collect crash logs and upload them to the server. There are a lot of third-par

When developing Android applications, you must use Log to monitor and debug program execution. In the previous article on Android Log system driver Logger source code analysis, we analyzed the source code of the driver Logger. in the previous article, we discussed the use of Log
