Android 调试桥 (adb) Android 调试桥 (adb) 是一种功能多样的命令行工具，可让您与设备进行通信。adb 命令可用于执行各种设备操作，例如安装和调试应用。adb 提供对 Unix shell（可用来在设备上运行各种命令）的访问权限。它是一种客户端-服务器程序，包括以下三个组件：

客户端：用于发送命令。客户端在开发机器上运行。您可以通过发出 adb 命令从命令行终端调用客户端。守护程序 (adbd)：用于在设备上运行命令。守护程序在每个设备上作为后台进程运行。服务器：用于管理客户端与守护程序之间的通信。服务器在开发机器上作为后台进程运行。 AndroidStudio 中显示的设备名称

在这里插入图片描述第一个 rockchip 来自系统属性: ro.product.product.manufacturer 第二个一般是ro.product.model PS 如果 manufacturer 和 model 一样, 那么会只显示一个的值.

ADB使能和控制USB调试 ADB调试的开关: 系统属性persist.sys.usb.config值里是否包含adb 系统设置数据库Settings.Global.ADB_ENABLED值是否为非0

frameworks/base/services/core/java/com/android/server/adb/AdbService.java

private static final String USB_PERSISTENT_CONFIG_PROPERTY = "persist.sys.usb.config"; private void initAdbState() { try { /* * Use the normal bootmode persistent prop to maintain state of adb across * all boot modes. */ mIsAdbUsbEnabled = containsFunction( SystemProperties.get(USB_PERSISTENT_CONFIG_PROPERTY, ""), UsbManager.USB_FUNCTION_ADB); mIsAdbWifiEnabled = "1".equals( SystemProperties.get(WIFI_PERSISTENT_CONFIG_PROPERTY, "0")); // register observer to listen for settings changes mObserver = new AdbSettingsObserver(); mContentResolver.registerContentObserver( Settings.Global.getUriFor(Settings.Global.ADB_ENABLED), false, mObserver); mContentResolver.registerContentObserver( Settings.Global.getUriFor(Settings.Global.ADB_WIFI_ENABLED), false, mObserver); } catch (Exception e) { Slog.e(TAG, "Error in initAdbState", e); } } private void setAdbEnabled(boolean enable, byte transportType) { if (DEBUG) { Slog.d(TAG, "setAdbEnabled(" + enable + "), mIsAdbUsbEnabled=" + mIsAdbUsbEnabled + ", mIsAdbWifiEnabled=" + mIsAdbWifiEnabled + ", transportType=" + transportType); } if (transportType == AdbTransportType.USB && enable != mIsAdbUsbEnabled) { mIsAdbUsbEnabled = enable; } else if (transportType == AdbTransportType.WIFI && enable != mIsAdbWifiEnabled) { mIsAdbWifiEnabled = enable; if (mIsAdbWifiEnabled) { if (!AdbProperties.secure().orElse(false) && mDebuggingManager == null) { // Start adbd. If this is secure adb, then we defer enabling adb over WiFi. SystemProperties.set(WIFI_PERSISTENT_CONFIG_PROPERTY, "1"); mConnectionPortPoller = new AdbDebuggingManager.AdbConnectionPortPoller(mPortListener); mConnectionPortPoller.start(); } } else { // Stop adb over WiFi. SystemProperties.set(WIFI_PERSISTENT_CONFIG_PROPERTY, "0"); if (mConnectionPortPoller != null) { mConnectionPortPoller.cancelAndWait(); mConnectionPortPoller = null; } } } else { // No change return; } if (enable) { startAdbd(); } else { stopAdbd(); } for (IAdbTransport transport : mTransports.values()) { try { transport.onAdbEnabled(enable, transportType); } catch (RemoteException e) { Slog.w(TAG, "Unable to send onAdbEnabled to transport " + transport.toString()); } } if (mDebuggingManager != null) { mDebuggingManager.setAdbEnabled(enable, transportType); } } private void startAdbd() { SystemProperties.set(CTL_START, ADBD); } private void stopAdbd() { if (!mIsAdbUsbEnabled && !mIsAdbWifiEnabled) { SystemProperties.set(CTL_STOP, ADBD); } }

使用设置系统属性ctl.start启动和ctl.stop停止adbd服务

增加系统控制是否启用USB调试

packages/modules/adb/daemon/main.cpp

int adbd_main(int server_port) { umask(0); signal(SIGPIPE, SIG_IGN); //..... #if defined(__ANDROID__) bool adb_usb_on = android::base::GetBoolProperty("persist.adb.adb_usb", false); if (access(USB_FFS_ADB_EP0, F_OK) == 0 && adb_usb_on) { // Listen on USB. usb_init(); is_usb = true; } #endif

修改系统属性后, 重启adbd服务生效.

默认网络ADB调试端口系统属性service.adb.tcp.port

修改 packages/modules/adb/daemon/main.cpp 需注意, 可能导致烧录后不能启动, 卡在下面LOG:
