android 监听电话去电接通瞬间[非来电]

首先感叹一下android强大，它可以把同一个apk里面得不同Actvity分别运行在不同的进程中，比如我想让自己的应用中Activity运行在Phone进程中，那么我需要做三个事情。

本文包含三个知识点：

1.监听去电接通 2.apk获取root权限 3. 运行时将apk push 到system/app

(1)

[java]
<activity
ndroid:process="com.android.phone"
            android:label="@string/app_name"
            android:name=".AutoCallActivity" >

        </activity>

    <activity
   android:process="com.android.phone"
                android:label="@string/app_name"
                android:name=".AutoCallActivity" >

            </activity> (2)

[java]
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.spreadst.drag"
    coreApp="true"
oid:sharedUserId="android.uid.system"
    android:versionCode="1"

    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.spreadst.drag"
        coreApp="true"
android:sharedUserId="android.uid.system"
        android:versionCode="1"
(3) [java]
   LOCAL_PACKAGE_NAME := autocall
    #LOCAL_CERTIFICATE := shared
LOCAL_CERTIFICATE := platform

LOCAL_PACKAGE_NAME := autocall
#LOCAL_CERTIFICATE := shared
LOCAL_CERTIFICATE := platform 为什么会有这个需求呢？TelephonyManager 中状态只有 IDLE 空闲状态，来电接通状态，拨打状态，没有去电接通状态，参考phone中得实现如下：
Phone phone = PhoneFactory.getDefaultPhone();
这个调用是不能运行在phone以外的进程中的，不信你可以试一下，请记住一个进程的主线程的looper是唯一的

原因如下：

[java]
if (sLooper != Looper.myLooper()) {
            throw new RuntimeException(
                "PhoneFactory.getDefaultPhone must be called from Looper thread");
        }

if (sLooper != Looper.myLooper()) {
            throw new RuntimeException(
                "PhoneFactory.getDefaultPhone must be called from Looper thread");
        }去电接通若干秒之后挂断代码如下，由于使用了hide class，所以必须在android源代码底下编译，当然你也可以通过反射、AIDL、class.jar等方式解决这个问题。

[java]
CallManager mCM = CallManager.getInstance();
   Phone phone = PhoneFactory.getDefaultPhone();

mCM.registerPhone(phone);
       mCM.registerForPreciseCallStateChanged(mHandler, PHONE_STATE_CHANGED, null);

CallManager mCM = CallManager.getInstance();
   Phone phone = PhoneFactory.getDefaultPhone();

mCM.registerPhone(phone);
       mCM.registerForPreciseCallStateChanged(mHandler, PHONE_STATE_CHANGED, null);
[java]
private Handler mHandler=new Handler(){

        public void handleMessage(android.os.Message msg) {
            switch (msg.what) {
            case PHONE_STATE_CHANGED:
                updatePhoneSateChange();
                break;
            default:
                break;
            }
        };

    };

    private Handler mHandler=new Handler(){

            public void handleMessage(android.os.Message msg) {
                switch (msg.what) {
                case PHONE_STATE_CHANGED:
                    updatePhoneSateChange();
                    break;
                default:
                    break;
                }
            };

        };
[java]
private void updatePhoneSateChange(){
        Call fgCall = mCM.getActiveFgCall();
        if (mCM.hasActiveRingingCall()) {
                fgCall = mCM.getFirstActiveRingingCall();
          }

        final Call.State state = fgCall.getState();
        switch (state) {
