logcat

I want to achieve the following but so far, no luck Open a file in the SD Card when the android application first started. Stream the logcat output to the file. When the application exits, stop the logcat streaming. In my ApplicationClass extends Application onCreate() method, I do this wwLogManager.openLogFile(); and here's the code in the openLogFile() private static final String LOGCAT_COMMAND = "logcat -v time -f "; String timestamp = Long.toString(System.currentTimeMillis()); String logFileName = BuildConstants.LOG_LOCATION + "_" + timestamp + ".log"; mLogFile = new File(Environment

很多时候遇到这样的情况，代码制作完成以后，想在模拟器上进行调试，于是Run as Android application，郁闷的是logcat中不显示任何内容 解决办法： 1.最直接的办法关闭Eclipse，重启 2.打开DDMS视图，在左侧“Devices”点击模拟器的名称"emulator-5554"，logcat就会显示出消失的log日志 如何打开DDMS 1.如下图所示，在“Open Perspective”（打开视图选项）中会有"DDMS"图标，单击“DDMS”图标即可 2.在devices区域选择模拟器，logcat中则会显示出改模拟器运行的日志 样也可以解决logcat日志不显示问题。 转载至 http://blog.csdn.net/android_robot/article/details/6903736 来源： http://www.cnblogs.com/draem0507/archive/2013/04/28/3049256.html

There is very awkward thing I am facing logcat is shown in debugging application but while running(not debugging) application it is not showing logcat . I tried restart it but nothing is happening. Cletus Ajibade In my case in Android 2.2, for some reason, Firebase was selected by default in the dropdown box marked above. So logs didn't drop. I just needed to change it to No Filters . Then it worked. I even tried restarting the logcat, that didn't work too. No Filters did the magic. Hope this helps someone. Edit : You can as well select Show only selected application for logcat to show only

adb的全称为Android Debug Bridge.是android司机经常用到的工具.但是问题是那么多命令写代码已经够费劲了,过段时间在次使用时压根记不住呀.本次的大餐就是为此开篇的.这一次我们不记命令.要用随时过来ctrl+F呀.哇哈哈哈! 本篇ADB集锦不管是常用还是冷门的都有.客观您随意看. 你能在本篇文章中收获什么? adb基本指令 Shell AM&PM adb模拟用户事件 logcat日志 常用节点 远程ADB 常用命令集 一. 基本指令 进入指定设备 adb -s serialNumber shell 查看版本 adb version 查看日志 adb logcat 查看设备 adb devices 连接状态 adb get-state 启动ADB服务 adb start-server 停止ADB服务 adb kill-server 电脑推送到手机 adb push local remote 手机拉取到电脑 adb pull remote local 二. adb shell下的am 与 pm 注:am和pm命令必须先切换到adb shell模式下才能使用 am am全称activity manager，你能使用am去模拟各种系统的行为，例如去启动一个activity，强制停止进程，发送广播进程，修改设备屏幕属性等等。当你在adb shell命令下执行am命令:

For some reason, LogCat doesn't report any stack traces anymore on crashes. Instead, I only get the following info: D/AndroidRuntime: Shutting down VM W/dalvikvm: threadid=1: thread exiting with uncaught exception (group=0x40dd3960) This is really weird because I've been working on the very same project for three months, and only recently (two, three days ago) the stack traces stopped showing. What could cause this? How can I get it to show stack traces again? I experienced the same problem. After upgrading Google Analytics to version 7 (or 7.3, I do not remember), my app always closes without

i am using opencv in android. but when i am adding Mat() in my code my application unexpectedly stops after launch. my error log is as below: FATAL EXCEPTION: main java.lang.UnsatisfiedLinkError: n_Mat at org.opencv.core.Mat.n_Mat(Native Method) at org.opencv.core.Mat.<init>(Mat.java:441) at com.example.imagepro.MainActivity.onCreate(MainActivity.java:36) at android.app.Activity.performCreate(Activity.java:4465) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1049) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1920) at android.app

I've got a hell of a lot of Log.i Log.d Log.e in my code for a recent app I've done. I'm about to publish this app and I don't really want people seeing it when they plug there phone into adb, but I do want it there for my own debugging. I was wanting to extend android.util.log and just have a boolean switch in there so I could just turn off the log when I publish and turn it on when developing but this class is final, am I missing a trick? I don't really want to go through my code an remove all, true if worst comes to worst I could do a ctrl+h global replace Log for //Log but that does suck

I'm developing an Android application and I would like to have some way to print debug statements as my code runs. Fortunately for me, Logcat was able to print out Log.d messages when I run my application on an Android 2.3.3 (API 10) emulator. However, when I tested the same exact application on a physical device (Samsung Galaxy S4 Android 4.2.2) I was unable to see anything other than dalvikvm and AndroidRuntime messages. com.android.internal.os.RuntimeInit <<<<<< 07-28 04:49:24.165: DEBUG/AndroidRuntime(6378): CheckJNI is OFF 07-28 04:49:24.165: DEBUG/AndroidRuntime(6378): setted country
