一、概述
Init进程启动后,最重要的一个进程就是Zygote进程,Zygote是所有应用的鼻祖。SystemServer和其他所有Dalivik虚拟机进程都是由Zygote fork而来。
Zygote进程由app_process启动,Zygote是一个C/S模型,Zygote进程作为服务端,其他进程作为客户端向它发出“孵化-fork”请求,而Zygote接收到这个请求后就“孵化-fork”出一个新的进程。
由于Zygote进程在启动时会创建Java虚拟机,因此通过fork而创建的应用程序进程和SystemServer进程可以在内部获取一个Java虚拟机的实例拷贝。
核心源码

/system/core/libutils/Threads.cpp
二、Zygote如何被启动的?
rc解析和进程调用
Init进程启动后,会解析init.rc文件,然后创建和加载service字段指定的进程。zygote进程就是以这种方式,被init进程加载的。
在 /system/core/rootdir/init.rc中,通过如下引用来load Zygote的rc:
import /init.${ro.zygote}.rc
其中${ro.zygote} 由各个厂家使用,现在的主流厂家基本使用zygote64_32,因此,rc文件为 init.zygote64_32.rc
2.1 init.zygote64_32.rc
第一个Zygote进程:
进程名:zygote
进程通过 /system/bin/app_process64来启动
启动参数:-Xzygote /system/bin --zygote --start-system-server --socket-name=zygote
socket的名称:zygote
service zygote /system/bin/app_process64 -Xzygote /system/bin --zygote --start-system-server --socket-name=zygote
class main
priority -20
user root //用户为root
group root readproc reserved_disk //访问组支持 root readproc reserved_disk
socket zygote stream 660 root system //创建一个socket,名字叫zygote,以tcp形式 ,可以在/dev/socket 中看到一个 zygote的socket
socket usap_pool_primary stream 660 root system
onrestart write /sys/android_power/request_state wake // onrestart 指当进程重启时执行后面的命令
onrestart write /sys/power/state on
onrestart restart audioserver
onrestart restart cameraserver
onrestart restart media
onrestart restart netd
onrestart restart wificond
onrestart restart vendor.servicetracker-1-1
writepid /dev/cpuset/foreground/tasks // 创建子进程时,向 /dev/cpuset/foreground/tasks 写入pid
第二个Zygote进程:zygote_secondary
进程通过 /system/bin/app_process32来启动
启动参数:-Xzygote /system/bin --zygote --socket-name=zygote_secondary --enable-lazy-preload
socket的名称:zygote_secondary
service zygote_secondary /system/bin/app_process32 -Xzygote /system/bin --zygote --socket-name=zygote_secondary --enable-lazy-preload
class main
priority -20
user root
group root readproc reserved_disk
socket zygote_secondary stream 660 root system //创建一个socket,名字叫zygote_secondary,以tcp形式 ,可以在/dev/socket 中看到一个 zygote_secondary的socket
socket usap_pool_secondary stream 660 root system
onrestart restart zygote
writepid /dev/cpuset/foreground/tasks
从上面可以看出,zygote是通过进程文件 /system/bin/app_process64 和/system/bin/app_process32 来启动的。对应的代码入口为:
frameworks/base/cmds/app_process/app_main.cpp
2.2 Zygote进程在什么时候会被重启
Zygote进程重启,主要查看rc文件中有没有 “restart zygote” 这句话。在整个Android系统工程中搜索“restart zygote”,会发现以下文件:
/frameworks/native/services/inputflinger/host/inputflinger.rc 对应进程: inputflinger
/frameworks/native/cmds/servicemanager/servicemanager.rc 对应进程: servicemanager
/frameworks/native/services/surfaceflinger/surfaceflinger.rc 对应进程: surfaceflinger
/system/netd/server/netd.rc 对应进程: netd
通过上面的文件可知,zygote进程能够重启的时机:
inputflinger 进程被杀 (onrestart)
servicemanager 进程被杀 (onrestart)
surfaceflinger 进程被杀 (onrestart)
netd 进程被杀 (onrestart)
zygote进程被杀 (oneshot=false)
system_server进程被杀(waitpid)
2.3 Zygote 启动后做了什么
init进程通过init.zygote64_32.rc来调用/system/bin/app_process64 来启动zygote进程,入口app_main.cpp
调用AndroidRuntime的startVM()方法创建虚拟机,再调用startReg()注册JNI函数;
通过JNI方式调用ZygoteInit.main(),第一次进入Java世界;
registerZygoteSocket()建立socket通道,zygote作为通信的服务端,用于响应客户端请求;
preload()预加载通用类、drawable和color资源、openGL以及共享库以及WebView,用于提高app启动效率;
zygote完毕大部分工作,接下来再通过startSystemServer(),fork得力帮手system_server进程,也是上层framework的运行载体。
zygote任务完成,调用runSelectLoop(),随时待命,当接收到请求创建新进程请求时立即唤醒并执行相应工作。

三、Zygote进程启动源码分析
3.1 Nativate-C世界的Zygote启动要代码调用流程
3.1.1 [app_main.cpp] main()
int main(int argc, char* const argv[])
{
//zygote传入的参数argv为“-Xzygote /system/bin --zygote --start-system-server --socket-name=zygote”
//zygote_secondary传入的参数argv为“-Xzygote /system/bin --zygote --socket-name=zygote_secondary”
...
while (i < argc) {
const char* arg = argv[i++];
if (strcmp(arg, "--zygote") == 0) {
zygote = true;
//对于64位系统nice_name为zygote64; 32位系统为zygote
niceName = ZYGOTE_NICE_NAME;
} else if (strcmp(arg, "--start-system-server") == 0) {
//是否需要启动system server
startSystemServer = true;
} else if (strcmp(arg, "--application") == 0) {
//启动进入独立的程序模式
application = true;
} else if (strncmp(arg, "--nice-name=", 12) == 0) {
//niceName 为当前进程别名,区别abi型号
niceName.setTo(arg + 12);
} else if (strncmp(arg, "--", 2) != 0) {
className.setTo(arg);
break;
} else {
--i;
break;
}
}
..
if (!className.isEmpty()) { //className不为空,说明是application启动模式
...
} else {
//进入zygote模式,新建Dalvik的缓存目录:/data/dalvik-cache
maybeCreateDalvikCache();
if (startSystemServer) { //加入start-system-server参数
args.add(String8("start-system-server"));
}
String8 abiFlag("--abi-list=");
abiFlag.append(prop);
args.add(abiFlag); //加入--abi-list=参数
// In zygote mode, pass all remaining arguments to the zygote
// main() method.
for (; i < argc; ++i) { //将剩下的参数加入args
args.add(String8(argv[i]));
}
}
...
if (!niceName.isEmpty()) {
//设置一个“好听的昵称” zygote\zygote64,之前的名称是app_process
runtime.setArgv0(niceName.string(), true /* setProcName */);
}
if (zygote) { //如果是zygote启动模式,则加载ZygoteInit
runtime.start("com.android.internal.os.ZygoteInit", args, zygote);
} else if (className) { //如果是application启动模式,则加载RuntimeInit
runtime.start("com.android.internal.os.RuntimeInit", args, zygote);
} else {
//没有指定类名或zygote,参数错误
fprintf(stderr, "Error: no class name or --zygote supplied.\n");
app_usage();
LOG_ALWAYS_FATAL("app_process: no class name or --zygote supplied.");
}
}
Zygote本身是一个Native的应用程序,刚开始的进程名称为“app_process”,运行过程中,通过调用setArgv0将名字改为zygote 或者 zygote64(根据操作系统而来),最后通过runtime的start()方法来真正的加载虚拟机并进入JAVA世界。
3.1.2 [AndroidRuntime.cpp] start()
void AndroidRuntime::start(const char* className, const Vector<String8>& options, bool zygote)
{
ALOGD(">>>>>> START %s uid %d <<<<<<\n",
className != NULL ? className : "(unknown)", getuid());
...
JniInvocation jni_invocation;
jni_invocation.Init(NULL);
JNIEnv* env;
// 虚拟机创建,主要是关于虚拟机参数的设置
if (startVm(&mJavaVM, &env, zygote, primary_zygote) != 0) {
return;
}
onVmCreated(env); //空函数,没有任何实现
// 注册JNI方法
if (startReg(env) < 0) {
ALOGE("Unable to register all android natives\n");
return;
}
jclass stringClass;
jobjectArray strArray;
jstring classNameStr;
//等价 strArray= new String[options.size() + 1];
stringClass = env->FindClass("java/lang/String");
assert(stringClass != NULL);
//等价 strArray[0] = "com.android.internal.os.ZygoteInit"
strArray = env->NewObjectArray(options.size() + 1, stringClass, NULL);
assert(strArray != NULL);
classNameStr = env->NewStringUTF(className);
assert(classNameStr != NULL);
env->SetObjectArrayElement(strArray, 0, classNameStr);
//strArray[1] = "start-system-server";
//strArray[2] = "--abi-list=xxx";
//其中xxx为系统响应的cpu架构类型,比如arm64-v8a.
for (size_t i = 0; i < options.size(); ++i) {
jstring optionsStr = env->NewStringUTF(options.itemAt(i).string());
assert(optionsStr != NULL);
env->SetObjectArrayElement(strArray, i + 1, optionsStr);
}
//将"com.android.internal.os.ZygoteInit"转换为"com/android/internal/os/ZygoteInit"
char* slashClassName = toSlashClassName(className != NULL ? className : "");
jclass startClass = env->FindClass(slashClassName);
//找到Zygoteinit类
if (startClass == NULL) {
ALOGE("JavaVM unable to locate class '%s'\n", slashClassName);
} else {
//找到这个类后就继续找成员函数main方法的Mehtod ID
jmethodID startMeth = env->GetStaticMethodID(startClass, "main",
"([Ljava/lang/String;)V");
if (startMeth == NULL) {
ALOGE("JavaVM unable to find main() in '%s'\n", className);
} else {
// 通过反射调用ZygoteInit.main()方法
env->CallStaticVoidMethod(startClass, startMeth, strArray);
}
}
//释放相应对象的内存空间
free(slashClassName);
ALOGD("Shutting down VM\n");
if (mJavaVM->DetachCurrentThread() != JNI_OK)
ALOGW("Warning: unable to detach main thread\n");
if (mJavaVM->DestroyJavaVM() != 0)
ALOGW("Warning: VM did not shut down cleanly\n");
}
start()函数主要做了三件事情,一调用startVm开启虚拟机,二调用startReg注册JNI方法,三就是使用JNI把Zygote进程启动起来。

3.1.3 [JniInvocation.cpp] Init()
Init函数主要作用是初始化JNI,具体工作是首先通过dlopen加载libart.so获得其句柄,然后调用dlsym从libart.so中找到
JNI_GetDefaultJavaVMInitArgs、JNI_CreateJavaVM、JNI_GetCreatedJavaVMs三个函数地址,赋值给对应成员属性,这三个函数会在后续虚拟机创建中调用.
bool JniInvocation::Init(const char* library) {
char buffer[PROP_VALUE_MAX];
const int kDlopenFlags = RTLD_NOW | RTLD_NODELETE;
/*
* 1.dlopen功能是以指定模式打开指定的动态链接库文件,并返回一个句柄
* 2.RTLD_NOW表示需要在dlopen返回前,解析出所有未定义符号,如果解析不出来,在dlopen会返回NULL
* 3.RTLD_NODELETE表示在dlclose()期间不卸载库,并且在以后使用dlopen()重新加载库时不初始化库中的静态变量
*/
handle_ = dlopen(library, kDlopenFlags); // 获取libart.so的句柄
if (handle_ == NULL) { //获取失败打印错误日志并尝试再次打开libart.so
if (strcmp(library, kLibraryFallback) == 0) {
// Nothing else to try.
ALOGE("Failed to dlopen %s: %s", library, dlerror());
return false;
}
library = kLibraryFallback;
handle_ = dlopen(library, kDlopenFlags);
if (handle_ == NULL) {
ALOGE("Failed to dlopen %s: %s", library, dlerror());
return false;
}
}
/*
* 1.FindSymbol函数内部实际调用的是dlsym
* 2.dlsym作用是根据 动态链接库 操作句柄(handle)与符号(symbol),返回符号对应的地址
* 3.这里实际就是从libart.so中将JNI_GetDefaultJavaVMInitArgs等对应的地址存入&JNI_GetDefaultJavaVMInitArgs_中
*/
if (!FindSymbol(reinterpret_cast<void**>(&JNI_GetDefaultJavaVMInitArgs_),
"JNI_GetDefaultJavaVMInitArgs")) {
return false;
}
if (!FindSymbol(reinterpret_cast<void**>(&JNI_CreateJavaVM_),
"JNI_CreateJavaVM")) {
return false;
}
if (!FindSymbol(reinterpret_cast<void**>(&JNI_GetCreatedJavaVMs_),
"JNI_GetCreatedJavaVMs")) {
return false;
}
return true;
}
3.1.4 [AndroidRuntime.cpp] startVm()
该函数主要作用就是配置虚拟机的相关参数,再调用之前 JniInvocation初始化得到的 JNI_CreateJavaVM_来启动虚拟机。
int AndroidRuntime::startVm(JavaVM** pJavaVM, JNIEnv** pEnv, bool zygote, bool primary_zygote)
{
JavaVMInitArgs initArgs;
...
// JNI检测功能,用于native层调用jni函数时进行常规检测,比较弱字符串格式是否符合要求,资源是否正确释放。
//该功能一般用于早期系统调试或手机Eng版,对于User版往往不会开启,引用该功能比较消耗系统CPU资源,降低系统性能。
bool checkJni = false;
property_get("dalvik.vm.checkjni", propBuf, "");
if (strcmp(propBuf, "true") == 0) {
checkJni = true;
} else if (strcmp(propBuf, "false") != 0) {
/* property is neither true nor false; fall back on kernel parameter */
property_get("ro.kernel.android.checkjni", propBuf, "");
if (propBuf[0] == '1') {
checkJni = true;
}
}
ALOGV("CheckJNI is %s\n", checkJni ? "ON" : "OFF");
if (checkJni) {
/* extended JNI checking */
addOption("-Xcheck:jni");
}
addOption("exit", (void*) runtime_exit); //将参数放入mOptions数组中
//对于不同的软硬件环境,这些参数往往需要调整、优化,从而使系统达到最佳性能
parseRuntimeOption("dalvik.vm.heapstartsize", heapstartsizeOptsBuf, "-Xms", "4m");
parseRuntimeOption("dalvik.vm.heapsize", heapsizeOptsBuf, "-Xmx", "16m");
parseRuntimeOption("dalvik.vm.heapgrowthlimit", heapgrowthlimitOptsBuf, "-XX:HeapGrowthLimit=");
parseRuntimeOption("dalvik.vm.heapminfree", heapminfreeOptsBuf, "-XX:HeapMinFree=");
parseRuntimeOption("dalvik.vm.heapmaxfree", heapmaxfreeOptsBuf, "-XX:HeapMaxFree=");
...
//检索生成指纹并将其提供给运行时这样,anr转储将包含指纹并可以解析。
std::string fingerprint = GetProperty("ro.build.fingerprint", "");
if (!fingerprint.empty()) {
fingerprintBuf = "-Xfingerprint:" + fingerprint;
addOption(fingerprintBuf.c_str());
}
initArgs.version = JNI_VERSION_1_4;
initArgs.options = mOptions.editArray(); //将mOptions赋值给initArgs
initArgs.nOptions = mOptions.size();
initArgs.ignoreUnrecognized = JNI_FALSE;
//调用之前JniInvocation初始化的JNI_CreateJavaVM_, 参考[4.1.3]
if (JNI_CreateJavaVM(pJavaVM, pEnv, &initArgs) < 0) {
ALOGE("JNI_CreateJavaVM failed\n");
return -1;
}
return 0;
}
3.1.5 [AndroidRuntime.cpp] startReg()
startReg首先是设置了Android创建线程的处理函数,然后创建了一个200容量的局部引用作用域,用于确保不会出现OutOfMemoryException,最后就是调用register_jni_procs进行JNI方法的注册
int AndroidRuntime::startReg(JNIEnv* env)
{
ATRACE_NAME("RegisterAndroidNatives");
//设置Android创建线程的函数javaCreateThreadEtc,这个函数内部是通过Linux的clone来创建线程的
androidSetCreateThreadFunc((android_create_thread_fn) javaCreateThreadEtc);
ALOGV("--- registering native functions ---\n");
//创建一个200容量的局部引用作用域,这个局部引用其实就是局部变量
env->PushLocalFrame(200);
//注册JNI方法
if (register_jni_procs(gRegJNI, NELEM(gRegJNI), env) < 0) {
env->PopLocalFrame(NULL);
return -1;
}
env->PopLocalFrame(NULL); //释放局部引用作用域
return 0;
}
3.1.6 [Thread.cpp] androidSetCreateThreadFunc()
虚拟机启动后startReg()过程,会设置线程创建函数指针gCreateThreadFn指向javaCreateThreadEtc.
void androidSetCreateThreadFunc(android_create_thread_fn func) {
gCreateThreadFn = func;
}
3.1.7 [AndroidRuntime.cpp] register_jni_procs()
它的处理是交给RegJNIRec的mProc,RegJNIRec是个很简单的结构体,mProc是个函数指针
static int register_jni_procs(const RegJNIRec array[], size_t count, JNIEnv* env)
{
for (size_t i = 0; i < count; i++) {
if (array[i].mProc(env) < 0) {/ /调用gRegJNI的mProc,参考[3.1.8]
return -1;
}
}
return 0;
}
3.1.8 [AndroidRuntime.cpp] gRegJNI()
static const RegJNIRec gRegJNI[] = {
REG_JNI(register_com_android_internal_os_RuntimeInit),
REG_JNI(register_com_android_internal_os_ZygoteInit_nativeZygoteInit),
REG_JNI(register_android_os_SystemClock),
REG_JNI(register_android_util_EventLog),
REG_JNI(register_android_util_Log),
...
}
#define REG_JNI(name) { name, #name }
struct RegJNIRec {
int (*mProc)(JNIEnv*);
};
gRegJNI 中是一堆函数指针,因此循环调用 gRegJNI 的mProc,即等价于调用其所对应的函数指针。
例如调用: register_com_android_internal_os_RuntimeInit
这是一个JNI函数动态注册的标准方法。
int register_com_android_internal_os_RuntimeInit(JNIEnv* env)
{
const JNINativeMethod methods[] = {
{ "nativeFinishInit", "()V",
(void*) com_android_internal_os_RuntimeInit_nativeFinishInit },
{ "nativeSetExitWithoutCleanup", "(Z)V",
(void*) com_android_internal_os_RuntimeInit_nativeSetExitWithoutCleanup },
};
//跟Java侧的com/android/internal/os/RuntimeInit.java 的函数nativeFinishInit() 进行一一对应
return jniRegisterNativeMethods(env, "com/android/internal/os/RuntimeInit",
methods, NELEM(methods));
}
3.2 Java世界的Zygote启动主要代码调用流程:
通过JNI调用ZygoteInit的main函数后,Zygote便进入了Java框架层,此前没有任何代码进入过Java框架层,换句换说Zygote开创了Java框架层。
3.2.1 [ZygoteInit.java]main.cpp
代码路径:frameworks\base\core\java\com\android\internal\os\ZygoteInit.java
main的主要工作:
- 调用preload()来预加载类和资源
- 调用ZygoteServer()创建两个Server端的Socket–/dev/socket/zygote 和 /dev/socket/zygote_secondary,Socket用来等待>- ActivityManagerService来请求Zygote来创建新的应用程序进程。
- 调用forkSystemServer 来启动SystemServer进程,这样系统的关键服务也会由SystemServer进程启动起来。
- 最后调用runSelectLoop函数来等待客户端请求
下面主要来分析这四件事。
public static void main(String argv[]) {
// 1.创建ZygoteServer
ZygoteServer zygoteServer = null;
// 调用native函数,确保当前没有其它线程在运行
ZygoteHooks.startZygoteNoThreadCreation();
//设置pid为0,Zygote进入自己的进程组
Os.setpgid(0, 0);
......
Runnable caller;
try {
......
//得到systrace的监控TAG
String bootTimeTag = Process.is64Bit() ? "Zygote64Timing" : "Zygote32Timing";
TimingsTraceLog bootTimingsTraceLog = new TimingsTraceLog(bootTimeTag,
Trace.TRACE_TAG_DALVIK);
//通过systradce来追踪 函数ZygoteInit, 可以通过systrace工具来进行分析
//traceBegin 和 traceEnd 要成对出现,而且需要使用同一个tag
bootTimingsTraceLog.traceBegin("ZygoteInit");
//开启DDMS(Dalvik Debug Monitor Service)功能
//注册所有已知的Java VM的处理块的监听器。线程监听、内存监听、native 堆内存监听、debug模式监听等等
RuntimeInit.enableDdms();
boolean startSystemServer = false;
String zygoteSocketName = "zygote";
String abiList = null;
boolean enableLazyPreload = false;
//2. 解析app_main.cpp - start()传入的参数
for (int i = 1; i < argv.length; i++) {
if ("start-system-server".equals(argv[i])) {
startSystemServer = true; //启动zygote时,才会传入参数:start-system-server
} else if ("--enable-lazy-preload".equals(argv[i])) {
enableLazyPreload = true; //启动zygote_secondary时,才会传入参数:enable-lazy-preload
} else if (argv[i].startsWith(ABI_LIST_ARG)) { //通过属性ro.product.cpu.abilist64\ro.product.cpu.abilist32 从C空间传来的值
abiList = argv[i].substring(ABI_LIST_ARG.length());
} else if (argv[i].startsWith(SOCKET_NAME_ARG)) {
zygoteSocketName = argv[i].substring(SOCKET_NAME_ARG.length()); //会有两种值:zygote和zygote_secondary
} else {
throw new RuntimeException("Unknown command line argument: " + argv[i]);
}
}
// 根据传入socket name来决定是创建socket还是zygote_secondary
final boolean isPrimaryZygote = zygoteSocketName.equals(Zygote.PRIMARY_SOCKET_NAME);
// 在第一次zygote启动时,enableLazyPreload为false,执行preload
if (!enableLazyPreload) {
//systrace 追踪 ZygotePreload
bootTimingsTraceLog.traceBegin("ZygotePreload");
EventLog.writeEvent(LOG_BOOT_PROGRESS_PRELOAD_START,
SystemClock.uptimeMillis());
// 3.加载进程的资源和类,参考[4.2.2]
preload(bootTimingsTraceLog);
EventLog.writeEvent(LOG_BOOT_PROGRESS_PRELOAD_END,
SystemClock.uptimeMillis());
//systrae结束 ZygotePreload的追踪
bootTimingsTraceLog.traceEnd(); // ZygotePreload
} else {
// 延迟预加载, 变更Zygote进程优先级为NORMAL级别,第一次fork时才会preload
Zygote.resetNicePriority();
}
//结束ZygoteInit的systrace追踪
bootTimingsTraceLog.traceEnd(); // ZygoteInit
//禁用systrace追踪,以便fork的进程不会从zygote继承过时的跟踪标记
Trace.setTracingEnabled(false, 0);
// 4.调用ZygoteServer 构造函数,创建socket,会根据传入的参数,
// 创建两个socket:/dev/socket/zygote 和 /dev/socket/zygote_secondary
//参考[4.2.3]
zygoteServer = new ZygoteServer(isPrimaryZygote);
if (startSystemServer) {
//5. fork出system server,参考[4.2.4]
Runnable r = forkSystemServer(abiList, zygoteSocketName, zygoteServer);
// 启动SystemServer
if (r != null) {
r.run();
return;
}
}
// 6. zygote进程进入无限循环,处理请求
caller = zygoteServer.runSelectLoop(abiList);
} catch (Throwable ex) {
Log.e(TAG, "System zygote died with exception", ex);
throw ex;
} finally {
if (zygoteServer != null) {
zygoteServer.closeServerSocket();
}
}
// 7.在子进程中退出了选择循环。继续执行命令
if (caller != null) {
caller.run();
}
}

什么是预加载:
预加载是指在zygote进程启动的时候就加载,这样系统只在zygote执行一次加载操作,所有APP用到该资源不需要再重新加载,减少资源加载时间,加快了应用启动速度,一般情况下,系统中App共享的资源会被列为预加载资源。
zygote fork子进程时,根据fork的copy-on-write机制可知,有些类如果不做改变,甚至都不用复制,子进程可以和父进程共享这部分数据,从而省去不少内存的占用。
预加载的原理:
zygote进程启动后将资源读取出来,保存到Resources一个全局静态变量中,下次读取系统资源的时候优先从静态变量中查找。

四、问题分析
4.1 为什么SystemServer和Zygote之间通信要采用Socket
进程间通信常用的是binder,为什么这里要采用socket呢。
主要是为了解决fork的问题:
UNIX上C++程序设计守则3:多线程程序里不准使用fork
Binder通讯是需要多线程操作的,代理对象对Binder的调用是在Binder线程,需要再通过Handler调用主线程来操作。
比如AMS与应用进程通讯,AMS的本地代理IApplicationThread通过调用ScheduleLaunchActivity,调用到的应用进程ApplicationThread的ScheduleLaunchActivity是在Binder线程,
需要再把参数封装为一个ActivityClientRecord,sendMessage发送给H类(主线程Handler,ActivityThread内部类)
主要原因:害怕父进程binder线程有锁,然后子进程的主线程一直在等其子线程(从父进程拷贝过来的子进程)的资源,但是其实父进程的子进程并没有被拷贝过来,造成死锁。
所以fork不允许存在多线程。而非常巧的是Binder通讯偏偏就是多线程,所以干脆父进程(Zgote)这个时候就不使用binder线程
4.2 为什么一个java应用一个虚拟机?
1.android的VM(vm==Virtual Machine )也是类似JRE的东西,当然,各方面都截然不同,不过有一个作用都是一样的,为app提供了运行环境
2.android为每个程序提供一个vm,可以使每个app都运行在独立的运行环境,使稳定性提高。
3.vm的设计可以有更好的兼容性。android apk都被编译成字节码(bytecode),在运行的时候,vm是先将字节码编译真正可执行的代码,否则不同硬件设备的兼容是很大的麻烦。
4.android(非ROOT)没有windows下键盘钩子之类的东西,每个程序一个虚拟机,各个程序之间也不可以随意访问内存,所以此类木马病毒几乎没有。
4.3 什么是Zygote资源预加载
预加载是指在zygote进程启动的时候就加载,这样系统只在zygote执行一次加载操作,所有APP用到该资源不需要再重新加载,减少资源加载时间,加快了应用启动速度,一般情况下,系统中App共享的资源会被列为预加载资源。
zygote fork子进程时,根据fork的copy-on-write机制可知,有些类如果不做改变,甚至都不用复制,子进程可以和父进程共享这部分数据,从而省去不少内存的占用。
4.4 Zygote为什么要预加载
应用程序都从Zygote孵化出来,应用程序都会继承Zygote的所有内容。
如果在Zygote启动的时候加载这些类和资源,这些孵化的应用程序就继承Zygote的类和资源,这样启动引用程序的时候就不需要加载类和资源了,启动的速度就会快很多。
开机的次数不多,但是启动应用程序的次数非常多。
4.5 Zygote 预加载的原理是什么?
zygote进程启动后将资源读取出来,保存到Resources一个全局静态变量中,下次读取系统资源的时候优先从静态变量中查找。
五、总结
Zygote启动流程结束,Zygote进程共做了如下几件事:
- 解析init.zygote64_32.rc,创建AppRuntime并调用其start方法,启动Zygote进程。
- 创建JavaVM并为JavaVM注册JNI.
- 通过JNI调用ZygoteInit的main函数进入Zygote的Java框架层。
- 通过ZygoteServer创建服务端Socket,预加载类和资源,并通过runSelectLoop函数等待如ActivityManagerService等的请求。
- 启动SystemServer进程。
