[SOLUTION]

这是google 默认行为，若贵司一定要改，请参考以下方法：

请尝试按照如下方法进行修改：

php?mod=tag&id=6090" target="_blank" class="relatedlink">Frameworks\base\media\java\android\media\MediaFocusControl.java：

1、import packages：

import com.android.internal.telephony.ITelephony;

import android.os.ServiceManager;

2、增加获取当前Phone Call State的方法getPhoneCallState()：

private int getPhoneCallState(){

int phoneCallState = TelephonyManager.CALL_STATE_IDLE;

TelephonyManager telephonyManager =

(TelephonyManager)mContext.getSystEMService(Context.TELEPHONY_SERVICE);

ITelephony telephonyService =

ITelephony.Stub.asInterface(ServiceManager.getService(Context.TELEPHONY_SERVICE));

if (telephonyService != null) {

Log.w(TAG, "getPhoneCallState: mTelephonyService != null");

try {

phoneCallState = telephonyService.getPreciseCallState();

Log.w(TAG, "getPhoneCallState: telephonyService.getPreciseCallState() = " +

phoneCallState);

} catch (RemoteException ex) {

if(telephonyManager != null){

phoneCallState = telephonyManager.getCallState();

Log.w(TAG, "getPhoneCallState: telephonyManager.getCallState() = " + phoneCallState);

}

Log.w(TAG, "Catch exception when getPreciseCallState: ex = "

+ ex.getMessage());

}

} else {

Log.w(TAG, "getPhoneCallState: telephonyService == null");

if(telephonyManager != null){

phoneCallState = telephonyManager.getCallState();

Log.w(TAG, "getPhoneCallState: telephonyManager.getCallState() = " + phoneCallState);

}

}

Log.w(TAG, "getPhoneCallState: phoneCallState = " + phoneCallState);

return phoneCallState;

}
