recommend that you read the Android development documentation. I personally say that it is better for you to find and explore on your own.
The implicit Intent call is also the same as the explicit call.
When you call Intent implicitly, if you want to start multiple programs with certain functions, for example, when you use the program to send files, there are many programs for you to choose? For example, Bluetooth or QQ. If there are multiple programs that can implement a function, a list wil

Intent sendintent = new Intent ();
Sendintent.setaction (intent.action_send);
Sendintent.putextra (Intent.extra_text, "This is me TEXT to send.");
Sendintent.settype ("Text/plain");
StartActivity (Intent.createchooser (Sendintent, Getresources (). GetText (r.string.send_to)));
Benefits of using Intent.createchooser ():
If you are Callintent.createchooser () for the intent, Android would always display
instead of calculationIn a situation where processor resources are tight and memory resources are relatively rich, it is possible to swap storage space for running speed. For example, if a sine or cosine function value is frequently calculated, the function value can be computed in advance and placed in memory for later arm lookups.

Today, we study the cooperation method of worker stackable, write two kinds of forms, although can work, but will appear the problem of memory not listening to growth; So the first method of the code message to the author, and now he did not reply to me. I finally gave up the two-way, directly using the worker, found that now performed 582,000 jobs, the memory does not grow, the speed is basically stable, the code is as follows: [PHP]View Plain copy print?

Understanding startup code (ADS)The startup Code refers to a piece of code executed by the processor at startup. The main task is to initialize the processor mode, set the stack, and initialize variables. since the above operations are closely related to the processor architecture and system configuration, compilation is generally used.Specifically to s64, the startup code is divided into two parts: one is related to the ARM7TDMI kernel, including the configuration of various exception vectors o
advantages of low power consumption, high density, and small size. Currently, Flash is classified into either nor or NAND. Nor flash memory can directly read the data stored in the chip, so the speed is relatively fast, but the price is relatively high. The address line of the nor chip is separated from the data line. Therefore, the nor chip can be connected to the data line like the SRAM, And the nor chip can be operated as the basic unit. Therefore, the transmission efficiency is very high, a
of the main kernel page? The kernel maintains a group of self-used page tables that reside in the so-called master kernel page global directory. After system initialization, this set of page tables have never been directly used by any process or any kernel thread. It is mainly used to provide reference models for global directory items corresponding to every common process in the system.
How does the kernel initialize its own page table? This process is divided into two phases. In fact, after
bit and higher performance, and easily upgrading it through interfaces like disks.
NOR features In-chip execution (XIP, eXecute In Place), so that applications can run directly In Flash memory without having to read the code into system RAM. NOR transmission efficiency is very high, in 1 ~ The small size of 4 MB has high cost efficiency, but the low write and erase speeds greatly affect its performance.
The NAND structure provides a very high unit de

All functions, including Ram and font generators, are included in a single chip. As long as there is a minimum microprocessing system, the module can be conveniently operated. The built-in 2 m-bit Chinese font Rom (cgrom) provides a total of 8192 Chinese fonts (16x16 lattice) and 16 k half width font Rom

Bib file parsing for winceBib is called binary image Builder, bib files are used in the final makeimage phase of the wince compilation process, and the purpose of the bib file is to instruct the build system how to build a binary image. All bib files are merged into a ce.bib file, and the package tool Romimage.exe determines which files are eventually included in the wince image based on the descriptions in the bib file, and the bib file also determines the allocation of wince device memory, suc
