principle knowledge.In binder IPC communication, binder is the communication medium, and parcel is the communication content. During the method remote call, the parameters are packaged into parcel format for transmission. The ibinder object is no exception. Let's take a look at writestrongbinder () in the parcel class (because the Java layer and native Layer Met

public int delta (long rawcontactid) of rawcontactid whose ID is long rawcontactid on the entityset. Public valuesdelta getsuperprimaryentry (final string mimetype) searches for the valuesdelta whose mime is mimetype in the collection. If there is issuperprimary () valuesdelta, it is directly returned; otherwise, the first isprimary () is returned () valuesdelta. If no isprimary () valuesdelta exists, the first valuesdelta is returned. Public int describecontents () returns 0. // nothing specia

proxy class will be created (as mentioned below). ③asbinder (): This method is used to return the current object itself.④ontransact (int code,parcel data,parcel reply,int Flags): This method is typically executed in the binder thread pool on the server side. That is, the remote request will be processed in this method. The code value passed is used to infer the client's request target, either Addperson or

article. We will analyze the following. First of all, to introduce the original rational knowledge.Binder IPC Communication, Binder is the medium of communication, parcel is the content of communication. method during a remote invocation, its parameters are packaged in parcel form to be passed. IBinder objects are no exception, let's take a look at the Writestrongbinder () in the

the invocation occurs within the process, and the same effect is done with the help of the IPC during the process. The data sent through Transact () is Parcel,parcel is a general buffer, with the exception of data with some metadata that describes its contents. Metadata is used to manage references to ibinder objects so that they can be saved when a buffer is moved from one process to another. This ensures
