详细分析Android中实现Zygote的源码

try {

sServerSocket = new LocalServerSocket(createFileDescriptor(fileDesc)); } catch(IOException ex) {

throw new RuntimeException("Error binding to local socket '" + fileDesc + "'", ex); }

} }

public class LocalServerSocket {

private final LocalSocketImpl impl; private final LocalSocketAddress localAddress;

private static final int LISTEN_BACKLOG = 50;

/**

* Create a LocalServerSocket from a file descriptor that's already * been created and bound. listen() will be called immediately on it.

* Used for cases where file descriptors are passed in via environment * variables.

*/ public LocalServerSocket(FileDescriptor fd) throws IOException {

impl = new LocalSocketImpl(fd); impl.listen(LISTEN_BACKLOG);

localAddress = impl.getSockAddress(); }

}

registerZygoteSocket很简单，就是创建一个服务端的socket。

预加载类和资源——preload

我们先来看一下preload函数实现：

static void preload() {
preloadClasses(); preloadResources();
preloadOpenGL(); }
