如何默认打开user 版本的USB debug 选项, 默认打开adb 连接
[Keyword]
量产版本 user usb debug root adb 连接
[Solution]
1. 在android 4.0 之前,这个设置是在frameworks/base/service/..../SystemServer.java 里面
设置会根据system property 的persist.service.adb.enable 来设置。您可以看到类似如代码:
- // make sure the ADB_ENABLED setting value matches the secure property value
- Settings.Secure.putInt(mContentResolver, Settings.Secure.ADB_ENABLED,
- "1".equals(SystemProperties.get("persist.service.adb.enable")) ? 1 : 0);
- // register observer to listen for settings changes
- mContentResolver.registerContentObserver(Settings.Secure.getUriFor(Settings.Secu
- ENABLED),false, new AdbSettingsObserver());
而这个persist.service.adb.enable 默认是放在在default.prop 中,在编译的时候在
build/core/main.mk 中确认,
- ifeq (true,$(strip $(enable_target_debugging)))
- # Target is more debuggable and adbd is on by default
- ADDITIONAL_DEFAULT_PROPERTIES += ro.debuggable=1 persist.service.adb.enable=1
- # Include the debugging/testing OTA keys in this build.
- INCLUDE_TEST_OTA_KEYS := true
- else # !enable_target_debugging
- # Target is less debuggable and adbd is off by default
- ADDITIONAL_DEFAULT_PROPERTIES += ro.debuggable=0 persist.service.adb.enable=0
- endif # !enable_target_debugging
您需要将: ADDITIONAL_DEFAULT_PROPERTIES += ro.debuggable=0
persist.service.adb.enable=0 改成
ADDITIONAL_DEFAULT_PROPERTIES += ro.debuggable=1 persist.service.adb.enable=1
2. 在android 4.0 之后,因为adb 的控制,统一使用了persist.sys.usb.config 来控制,于是对
应的设置点也改到了frameworks/base/service/...../usb/UsbDeviceManager.java 中,您也可以
看到类似的代码如:
- public UsbHandler(Looper looper) {
- // persist.sys.usb.config should never be unset. But if it is, set it to "adb"
- // so we have a chance of debugging what happened.
- mDefaultFunctions = SystemProperties.get("persist.sys.usb.config", "adb");
- // sanity check the sys.usb.config system property
- // this may be necessary if we crashed while switching USB configurations
- String config = SystemProperties.get("sys.usb.config", "none");
- if (!config.equals(mDefaultFunctions)) {
- Slog.w(TAG, "resetting config to persistent property: " + mDefaultFunctions);
- SystemProperties.set("sys.usb.config", mDefaultFunctions);
- }
- mCurrentFunctions = mDefaultFunctions;
- String state = FileUtils.readTextFile(new File(STATE_PATH), 0, null).trim();
- updateState(state);
- mAdbEnabled = containsFunction(mCurrentFunctions, UsbManager.USB_FUNCTION_ADB);
- public void systemReady() {
- // make sure the ADB_ENABLED setting value matches the current state
- Settings.Secure.putInt(mContentResolver, Settings.Secure.ADB_ENABLED, mAdbEnabled ?
- 1 : 0);
而这个persist.sys.usb.config 中adb 的配置是在alps/build/tools/post_process_props.py 中
根据ro.debuggable = 1 or 0 来设置,1 就是开启adb, 0 即关闭adb debug. 而这个
ro.debuggable 也是在alps/build/core/main.mk 中设置,和2.3 修改类似
不过您这样打开之后,对于user 版本adb shell 开启的还是shell 权限,而不是root 权限,如果
您需要root 权限,需要再改一下system/core/adb/adb.c 里面的should_drop_privileges() 这个
函数,在#ifndef ALLOW_ADBD_ROOT 时return 0; 而不是return 1; 即可。
---------------------------------------------------------------------------------------
1. 根据编译命令确定ro.debuggable
build/core/main.mk
- ## user/userdebug ##
- user_variant := $(filter user userdebug,$(TARGET_BUILD_VARIANT))
- enable_target_debugging := true
- tags_to_install :=
- ifneq (,$(user_variant))
- # Target is secure in user builds.
- ADDITIONAL_DEFAULT_PROPERTIES += ro.secure=1
- ifeq ($(user_variant),userdebug)
- # Pick up some extra useful tools
- tags_to_install += debug
- # Enable Dalvik lock contention logging for userdebug builds.
- ADDITIONAL_BUILD_PROPERTIES += dalvik.vm.lockprof.threshold=500
- else
- # Disable debugging in plain user builds.
- enable_target_debugging :=
- endif
- # enable dex pre-optimization for all TARGET projects in default to
- # speed up device first boot-up
- #add by yanqi.liu for costomization @{
- ifneq ($(JRD_IS_GOAL_PERSO),true)
- WITH_DEXPREOPT := true
- endif
- #}
- # Turn on Dalvik preoptimization for user builds, but only if not
- # explicitly disabled and the build is running on Linux (since host
- # Dalvik isn't built for non-Linux hosts).
- ifneq (true,$(DISABLE_DEXPREOPT))
- ifeq ($(user_variant),user)
- ifeq ($(HOST_OS),linux)
- ifneq ($(JRD_IS_GOAL_PERSO),true)
- WITH_DEXPREOPT := true
- endif
- endif
- endif
- endif
- # Disallow mock locations by default for user builds
- ADDITIONAL_DEFAULT_PROPERTIES += ro.allow.mock.location=0
- else # !user_variant
- # Turn on checkjni for non-user builds.
- # Kirby: turn off it temporarily to gain performance {
- # ADDITIONAL_BUILD_PROPERTIES += ro.kernel.android.checkjni=1
- # ADDITIONAL_BUILD_PROPERTIES += ro.kernel.android.checkjni=0
- # } Kirby
- # Set device insecure for non-user builds.
- ADDITIONAL_DEFAULT_PROPERTIES += ro.secure=0
- # Allow mock locations by default for non user builds
- ADDITIONAL_DEFAULT_PROPERTIES += ro.allow.mock.location=1
- endif # !user_variant
- # always enable aed
- ADDITIONAL_DEFAULT_PROPERTIES += persist.mtk.aee.aed=on
- # Turn on Jazz AOT by default if not explicitly disabled and the build
- # is running on Linux (since host Dalvik isn't built for non-Linux hosts).
- ifneq (true,$(DISABLE_JAZZ))
- ifeq ($(strip $(MTK_JAZZ)),yes)
- ifeq ($(HOST_OS),linux)
- # Build host dalvikvm which Jazz AOT relies on.
- WITH_HOST_DALVIK := true
- WITH_JAZZ := true
- endif
- endif
- endif
- ifeq (true,$(strip $(enable_target_debugging)))
- # Target is more debuggable and adbd is on by default
- ADDITIONAL_DEFAULT_PROPERTIES += ro.debuggable=1
- ADDITIONAL_DEFAULT_PROPERTIES += ro.adb.secure=0
- # Include the debugging/testing OTA keys in this build.
- INCLUDE_TEST_OTA_KEYS := true
- else # !enable_target_debugging
- # Target is less debuggable and adbd is off by default
- ADDITIONAL_DEFAULT_PROPERTIES += ro.debuggable=0
- ADDITIONAL_DEFAULT_PROPERTIES += ro.adb.secure=1
- endif # !enable_target_debugging
2. 确定默认的usb功能
build/tools/post_process_props.py
- # Put the modifications that you need to make into the /system/build.prop into this
- # function. The prop object has get(name) and put(name,value) methods.
- def mangle_build_prop(prop):
- #pass
- #If ro.mmitest is true, then disable MTP, add mass_storage for default
- if prop.get("ro.mmitest") == "true":
- prop.put("persist.sys.usb.config", "mass_storage")
- # If ro.debuggable is 1, then enable adb on USB by default
- # (this is for userdebug builds)
- if prop.get("ro.build.type") == "eng":
- val = prop.get("persist.sys.usb.config").strip('\r\n')
- if val == "":
- val = "adb"
- else:
- val = val + ",adb"
- prop.put("persist.sys.usb.config", val)
- # UsbDeviceManager expects a value here. If it doesn't get it, it will
- # default to "adb". That might not the right policy there, but it's better
- # to be explicit.
- if not prop.get("persist.sys.usb.config"):
- prop.put("persist.sys.usb.config", "none");
- # Put the modifications that you need to make into the /system/build.prop into this
- # function. The prop object has get(name) and put(name,value) methods.
- def mangle_default_prop(prop):
- # If ro.debuggable is 1, then enable adb on USB by default
- # (this is for userdebug builds)
- if prop.get("ro.debuggable") == "1":
- val = prop.get("persist.sys.usb.config")
- if val == "":
- val = "adb"
- else:
- val = val + ",adb"
- prop.put("persist.sys.usb.config", val)
- # UsbDeviceManager expects a value here. If it doesn't get it, it will
- # default to "adb". That might not the right policy there, but it's better
- # to be explicit.
- if not prop.get("persist.sys.usb.config"):
- prop.put("persist.sys.usb.config", "none");
