In general, we use parcelable when we pass objects between activity. such as writing a class, on this class marked implements Parcelable and implementation interface can be used Intent.putextra (String, parcelable). For passing enum objects, it is assumed that this method is also used, that is, like http://stackoverflow.com/questions/2836256/ Passing-enum-or-object-through-an-intent-the-best-solution inside the 3 floor said:[Java]View Plaincopy

. The conversion process is to make the service automatically comply with the binder framework design specifications at the code level, and automatically solves the second of the two core issues mentioned above. The generated java files actually include three classes:

[Android Java] design pattern code: Observer Pattern
The observer is like a person who is interested in many things, like music, electronic products, games, and stocks. Changes in these things can attract the attention of fans and always pay attention to them. In the code, we also have such a way to design some interesting ideas. Today, I will write a Demo to describe this idea.
Well, programmers are not good at speaking. Read the code first.

It is clear that getService is supposed to interact with ServiceManger, as shown below:

* outService){ const sp
sm = defaultServiceManager(); if (sm != NULL) { *outService = interface_cast
(sm->getService(name)); if ((*outService) != NULL) return NO_ERROR; } return NAME_NOT_FOUND;}
Here, we can see the interaction process between the common client and SM. Here, we implement the client t
The Android interprocess communication is based on the design pattern (1-1) of the proxy (proxy) and stub (pile or stub). wherein, Proxy will be the special interface into a universal interface, the stub will be the universal interface into a special interface, the data between the two of the conversion through parcel (packaging), Proxy is often used as a data sending agent, through the parcel data package

Note: In addition, red hat linux also provides a partition software called fips. However, this partition software is dangerous and should not be recommended. Although many people have successfully used fips to partition their hard disks, this does not guarantee that fips will run properly in your system. In addition, red hat linu
