安卓通话状态监控之挂电话部分

本文主要是介绍安卓通话状态监控之挂电话部分，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

挂电话部分

在app/phone下

<span style="font-size:18px;"> void handleOnscreenButtonClick(int id) {if (DBG) log("handleOnscreenButtonClick(id " + id + ")...");switch (id) {// Actions while an incoming call is ringing:case R.id.endAllCallsButton:PhoneUtils.hangupAll(mPhone);break;default:Log.w(LOG_TAG, "handleOnscreenButtonClick: unexpected ID " + id);break;}mApp.pokeUserActivity();
</span></span>

这里的case R.id.endAllCallsButton:就是挂掉所有电话

PhoneUtils.hangupAll(mPhone);关键之一就在于找这个mphone从哪来的

<span style="font-size:18px;">void setPhone(Phone phone, CallManager cm) {if (phone != mPhone || mCM != cm) {mCM = cm;mPhone = phone;if (DBG) log("switching to phone: " + phone.getPhoneName());if (mInCallControlState != null) {mInCallControlState.setCM(cm);}if (mManageConferenceUtils != null) {mManageConferenceUtils.setCM(cm);}}}</span>

整个class里就这个地方初始化了mphone，查找哪里调用了InCallScreen.java

<span style="font-size:18px;"> setPhone(DualPhoneController.getInstance().getActivePhone(), DualPhoneController.getInstance().getActiveCM());</span>

查找getActivePhone()

<span style="font-size:18px;">    Phone getActivePhone() {if (isPrimaryOnSim1()) {return mActiveSimId == ID_SIM_1 ? mApp.phone : mApp.phone2;}return mActiveSimId == ID_SIM_1 ? mApp.phone2 : mApp.phone;}
</span>

查找mApp

<span style="font-size:18px;">private DualPhoneController(PhoneGlobals app) {mApp = app;mCM = app.mCM;mCM2 = app.mCM2;mPrimaryId = Settings.Global.getInt(PhoneGlobals.getInstance().getContentResolver(),Settings.Global.MOBILE_DATA_SIM,TelephonyConstants.DSDS_SLOT_1_ID);}
</span>

查找这个函数被调用的地方

<span style="font-size:18px;"> /* package */ static DualPhoneController init(PhoneGlobals app) {synchronized (NotificationMgr.class) {if (sInstance == null) {sInstance = new DualPhoneController(app);} else {Log.wtf(LOG_TAG, "init() called multiple times!  sInstance = " + sInstance);}return sInstance;}}</span>

所有的问题都在与不论是PhoneGlobals.java还是DualPhoneController.java都在phone这个app内部，而无法在service或者framework里导出

不过在PhoneGlobals.java看到

phone = PhoneFactory.getDefaultPhone();
phone2 = PhoneFactory.get2ndPhone();

最终还是用了service里的方法，所以mphone的追踪到此结束

这个

<span style="font-size:18px;"><span style="font-size:18px;">PhoneUtils的定义在package/apps/phone里</span></span>

<span style="font-size:18px;"><span style="font-size:18px;"> static void hangupAll(Phone phone) {if (phone == null)return ;String[] request = new String[1];request[0] = Integer.toString(OemTelephonyConstants.RIL_OEM_HOOK_STRING_RELEASE_ALL_CALLS);phone.invokeOemRilRequestStrings(request, null);}
</span></span>

这个phone的定义在opt/telephony目录下
这里追踪/frameworks/opt/telephony/src/java/com/android/internal/telephony目录下的ril.java

<span style="font-size:18px;"><span style="font-size:18px;">  public void invokeOemRilRequestStrings(String[] strings, Message response) {RILRequest rr= RILRequest.obtain(RIL_REQUEST_OEM_HOOK_STRINGS, response, mIs2ndRil);if (RILJ_LOGD) riljLog(rr.serialString() + "> " + requestToString(rr.mRequest));rr.mParcel.writeStringArray(strings);send(rr);}</span></span>

从这里看来phone的这个类型非常关键，phone的定义在

/third/frameworks/opt/telephony/src/java/com/android/internal/telephony$

而在eclipse中想导入这个telephony的包，则去看opt/telephony的目录下的android.mk文件

<span style="font-size:18px;"><span style="font-size:18px;">ifeq ($(TARGET_BUILD_JAVA_SUPPORT_LEVEL),platform)LOCAL_PATH := $(call my-dir)include $(CLEAR_VARS)LOCAL_AIDL_INCLUDES := $(LOCAL_PATH)/src/java
LOCAL_SRC_FILES := $(call all-java-files-under, src/java) \$(call all-Iaidl-files-under, src/java) \$(call all-logtags-files-under, src/java)LOCAL_SRC_FILES += $(call all-java-files-under, src/com/asus/dsds/base)
ifeq ($(BOARD_USES_QCOM_HARDWARE),true)
LOCAL_SRC_FILES += $(call all-java-files-under, src/com/asus/dsds/qc)
elseifeq ($(INTEL_INGREDIENTS_VERSIONS),true)LOCAL_SRC_FILES += $(call all-java-files-under, src/com/asus/dsds/intel)elseLOCAL_SRC_FILES += $(call all-java-files-under, src/com/asus/dsds/default)endif
endifLOCAL_JAVA_LIBRARIES := voip-common
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE := telephony-commoninclude $(BUILD_JAVA_LIBRARY)# Include subdirectory makefiles
# ============================================================
include $(call all-makefiles-under,$(LOCAL_PATH))endif # JAVA platform</span></span>

这里说的

<span style="font-size:18px;"><span style="font-size:18px;">LOCAL_MODULE := telephony-common</span></span>

就是生成的jar的名字

而在out目录下搜索这个包名

find . -name telephony-common*

发现./target/common/obj/JAVA_LIBRARIES/telephony-common_intermediates这个目录下有个classes.jar,将其导入后就发现可以识别phone的类型和callmanager的类型。

<span style="font-size:18px;"><span style="font-size:18px;"><span style="font-size:18px;"><span style="font-size:18px;">public boolean hangupCall() {enforceCallingOrSelfPermission(MODIFY_PHONE_STATE, null);if (mCM.hasActiveFgCall()) {return PhoneUtils.hangupActiveCall(mCM.getActiveFgCall());} else if (mCM.hasActiveRingingCall()) {return PhoneUtils.hangupRingingCall(mCM.getFirstActiveRingingCall());} else if (mCM.hasActiveBgCall()) {return PhoneUtils.hangupHoldingCall(mCM.getFirstActiveBgCall());}</span></span></span></span>

从上面的代码里看，一个PhoneUtils和mCM是需要获取，

获取mcm

<span style="font-size:18px;"><span style="font-size:18px;">mCM1 = CallManager.getInstance();
mCM2 = CallManager.getInstance2();</span></span>

获取PhoneUtils

由于并没看到PhoneUtils的定义所以这个类应该是只要包含一个jar包即可使用
