Types of ANRThe type of ANR is broadly divided into the following three types1, the main thread to the input event in 5 seconds did not finish processing the prerequisite for this ANR is to have an input event, if the user does not t

Log status in Android is very important, if as an Android programmer can not analyze log this, is not an introduction to Android. Let's say how to handle the log file.When will the log file be generated?Log generation We all know, we all know through DDMS to see log, but when will produce log file? A log file is typically generated in the following situations.1, program abnormal exit, uncaused exception2, program forced shutdown, Force Closed (FC)3, the program is not responding, application no

1. What is ANR? ANR (application not responding) means that the application has no response. 2. What is the cause of ANR? The root cause of ANR is that the app blocks the UI thread. In the Android system, each app has only one UI thread, which is generated by default when the app is created. The UI thread initialize

On Android, if your application has been unresponsive for a while, the system will display a dialog box to the userThis dialog box is called the application unresponsive (anr:application not responding) dialog box. Users can choose to haveThe program continues to run, but when they use your application, they do not want to process the dialog box every time. Therefore, the processThe design of the response performance is important so that the system does not show the

refer to the website loader for details.3.2.6 Special attentionWhen using thread and Handlerthread, it is recommended that you set the thread to a lower priority for better results:Process.setThreadPriority(THREAD_PRIORITY_BACKGROUND);Because if you do not have any priority settings, the thread default and UI thread you create have the same priority, you know. The same priority thread, CPU scheduling may still block out your UI Thread, resulting in A

Android ANR monitoring and analysis, and androidanr monitoring Reprinted from: http://www.10tiao.com/html/203/201609/2649752287/1.html Application Not Responding (ANR): The system detects that the APP has Not responded for a long time. Although ANR is Not abnormal, it seriously affects the user experience. Therefore, it is necessary to report and resolve

In fact, when the user volume of Android projects is particularly large, some small problems will be magnified, the ANR problem is a typical example.Some of the ANR problems will only occur in the user's actual use of the situation, when the system resources are more nervous and other special cases will be encountered, and these ANR problems are due to our code i

First, ANR introductionOn Android, if your application is unresponsive for a period of time, a dialog box is displayed to the user called the application unresponsive (anr:application not responding) dialog box. The user can select "Wait" and let the program continue to run, or "Force shutdown". So a smooth and reasonable application can not appear ANR, and let users each time to process this dialog box. Th

I. Introduction The ANR problem is a common and troublesome problem in Android. It is difficult to analyze the cause in many cases. Ii. ANR Definition Next let's take a lookBaidu encyclopediaDefinition for ANR: ANR problems are often caused by complex and time-consuming operations in the main (main thread) thread, su

About ANR ANR, is the abbreviation for "Application Not Responding", which is "application unresponsive". In Android, Activitymanagerservice (AMS) and Windowmanagerservice (WMS) Monitor the response time of the application, If the application main thread (that is, the UI thread) has not finished processing the input event during the timeout period, or if a particular operation has not been performe

The following is a section of the ANR log, mainly implemented in Windowmanagerservice.java and Activitymanagerservice.java.W/windowmanager (2183): Key dispatching timed out sending to Com.android.camera/com.android.camera.cameraW/windowmanager (2183): Previous Dispatch state: {{keyevent{action=0 code=4 repeat=0 meta=0 scancode=158 mflags=8} to Wind ow{4622ad58 Com.android.camera/com.android.camera.camera Paused=false} @ 5419631 lw=window{4622ad58 Com.

For people engaged in Android development, encountering ANR (application not responding) is a more common problem. In general, if a ANR occurs, the system will generate the trace file in the/data/anr/directory, by analyzing the trace file, you can locate the cause of the ANR. There are many reasons for the

This may happen. The code you write passes all the performance tests in the world, but it still makes users feel uncomfortable when they try to use your application. Some areas where the application is not responsive include: slow response, long suspension or freezing, or a long time to process input. On Android, if your application is not responsive for a period of time, the system will display you a dialog box called ANR: application not responding.

One: What is ANRAnr:application not responding, i.e. application unresponsiveII: Type of ANRThere are generally three types of ANR:1. Keydispatchtimeout (5 seconds)--key type keys or touch events are not responding at a specific time2. Broadcasttimeout (seconds)--broadcastreceiver cannot process the completion at a specific time3. Servicetimeout (seconds)-small probability type service cannot process completion at a specific timeThree: Keydispatchtime

Log plays a very important role in Android. As an android programmer, log analysis cannot be performed. Therefore, there is no entry level for Android. Next we will talk about how to process log files. When will log files be generated?We all know that the log is generated, and we all know that the log is viewed through ddms. But when will the log file be generated? Generally, log files are generated in the following situations.1. The program exits unexpectedly, and the uncaused exception2. Force

When the ANR occurs , you first need to view the log information and the trace file (the system will be /data/anr/ generated under directory Trace files ) Analyze the cause of ANR . The following analysis does not solve all the ANRencountered, but the program itself causes the ANR problem basically can find the reason.
