If your WP application already uses the Sterling database, use Sterling to generate a tombstone (Tombtsone. Jeremy Likness's blog details how to use Sterling to implement Tombstone in the MVVM architecture. There are several main points: 1. Define a Tombstone data class. The Singletone Serialization mentioned in the Sterling User Guide is used. public class Tom
WP7 does not support multitasking, but provides a tombstone mechanism. In general, it provides five graves for you. If you want your program to enter the "background ", then you will be buried there. If you want to enable your "background" program, you will dig out the program from the grave and load the relevant data into the control from the memory, in simple terms, it is a zombie. However, if you have more than five "backend" programs, you will be
1. WP third-party applications Program Restrictions WP allows only one third-party application to run at a time in the foreground. This means that the user can only start one third-party application when operating the mobile phone, making people think that WP is a single-task operating system. However, unlike the generally-understood single-task operating system, WP provides a mechanism, which is Tombstone (to
UnderstandingWindows Phone7 application execution model, tombstone mechanism, starter and Selector and more-- Part 1 Author: Yochay kiriaty The articles in this series have a name that is so long and very loud. I believe it will be very good. Of course you should judge it. However, the reason for such a long name is simple. These "big" words can briefly summarize all aspects of the execution model. If you want to continuously improve the user experien
WP7ProgramAs shown in: The sleep state and the tombstone state are confusing. The program stops running during sleep state, but the difference is that the entire process still exists in the memory. When this program is restored, you do not need to create a new instance. In this way, the program recovery and switching are accelerated, and we do not need to restore the tombstone data from the sleep state
able to restore at any time, but you need to manually click the Recycle Bin to restore files and confirm. Files put into the Recycle Bin everybody knows it's about taking up space? That is, resources. and WP7 is more like a running task after the abort of the necessary data packaging made a snapshot and storage, note that this time is "abort." Then the step is to directly delete and empty the Recycle Bin, but the data is actually still on the hard disk, but the logical deletion, as long as not
Background In the Windows Phone 8 development process, tombstone's processing really makes us love and hate, and it can makeProgramIt seems to be running all the time. However, it is very troublesome to process the tombstone. In the traditional method, we need to put the state to be saved after the deactived event of the program is triggered, and then load the state after the user returns. However, if our program adopts the mvvm architecture, the si
Several terms: Name Description Launched Start a new program Closed Use the back button to close the program Deactivated A program is running. Press the START key to stop the program. Then, the program enters the tombstone. Activated The program is revived from the tombstone, that is, activated Then the life cycle of our program is roughly s
data from device sensors, such as GPS. If the program is not running, I will not be able to tell you that you have finished the 4-mile journey you want. In addition to these two cases, I do not think that the program must be run in the background. (If your program is in any of the above categories, you can call on the "authority" to access a "super API" that enables the program to run in the background ". But I still want to remind you ...... Provide a very good reason for obtaining access per
The following figure shows the life cycle of the WP7 program:The sleep state and the tombstone state are confusing. The program stops running during sleep state, but the difference is that the entire process still exists in the memory. When this program is restored, you do not need to create a new instance.

How to debug tombstone occurring in Android The following three types of problems are more likely to occur in Android: Force Close/anr/tombstone The first two are mainly to look at the current process or system framework layer state and stack can be analyzed, this article mainly discusses the situation of Tombstone. Tombstone
the validity of the base site, you can try to calculate the symbol for the 0X518254A5 (func_a+56): 0x518254a5- 0x51825000 = 0x4a5. Then use Addr2line query 0x4a5 to get hello-jni.c:34. There is another way to calculate the available addresses, as well as the individual symbol information provided in the stack: Example 0x518254a5 (func_a+56), which is then mentioned objdump can be used to directly input the. So, this will come out the entire LIB assembly information. Then you can find "0XXXXXXXX
Modify DC Tombstone Survival Time U Case Requirements How do I change the time limit for an authoritative restore? U Knowledge Tips When you delete an object (such as a user account, OU, and so on) in AD, the object is not actually deleted, but is moved to a special container. When the object is eventually deleted, it is determined by the tombstone's survival time. Tombstone lifetime refers to the time inte
Background Tombstone in the development process of Windows Phone 8 really makes us love and hate, it can make the program seems to be running. But dealing with tombstones is a very troublesome thing, the traditional way we need to be in the program Deactived event triggered, the need to save the state to put in, and then the user back to load out. And if our program uses the MVVM architecture, the situation will be more complex and complex. Believe t
The following executable modes are available for phone7 : tombstoning , page state , application state , persistent data , transient state . tombstone and transient state because they can simulate multiple tasks. In tombstoned mode, the application is terminated by the operating system (this can reduce resource usage), you need to save the transient state , it is used to restore the original state of the application after the applicatio
direct crash, my mother, such a big lump, what things ah, totally do not understand, no clue Satan. This nnd Android out of the question, popping up such a large heap of addresses, to make wool.In fact, I can be very responsible to tell you, brothers so much actually I can not understand, in my eyes except the red and blue places, all the rest is nonsense.

Just now, when I was running the Win8 Metro app, I suddenly thought of the program lifecycle issue that had been very tangled for some time ago. I don't know where to implement the tombstone mechanism. I think there may be improvements in the RP version. After some tests, Conclusion: The RP version automatically implements the tombstone mechanism, 10 ~ after closing the program (window pulling down or Alt +
