【问题描述】：
我编写了 PhoneStateListener，它通过广播接收器监听电话事件。我在TelephonyManager.CALL_STATE_IDLE 收到以下错误
06-10 13:50:48.360: 详细/错误（4686）：URI： 内容：//com.android.contacts/phone_lookup/， 呼叫用户：com.emergency.alert， 调用包：com.emergency.alert
代码如下
public class MyPhoneStateListener extends PhoneStateListener {
public Context context;
//private static MediaPlayer mMediaPlayer;
private Uri alert;
private static Uri prev_ringtone;
public static final String PREFS_NAME = "ealertprefs";
public static int phone_state;
public EmergencyAdapter dbHelper;
private String fetchName;
@Override
public void onCallStateChanged(int state, String incomingNumber) {
// TODO Auto-generated method stub
switch(state){
case TelephonyManager.CALL_STATE_IDLE:
try {

Log.v("ERROR", e.getMessage());

private void retrieve_phone() {
AudioManager am = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
am.setRingerMode(phone_state);
RingtoneManager.setActualDefaultRingtoneUri(context, RingtoneManager.TYPE_RINGTONE, prev_ringtone);
}

String[] projection = new String[] {
PhoneLookup._ID,
PhoneLookup.DISPLAY_NAME };

Uri contactUri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));
// query time
Cursor c = context.getContentResolver().query(contactUri, projection, null, null, null);
// if the query returns 1 or more results
// return the first result
Log.v("ELIST", "LOG");
if (c.moveToFirst()) {

fetchName = cursor.getString(1);
Log.v("CALLER", fetchName);
return true;
}

am.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
}
private void send_notification(){
NotificationManager notifier = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
int icon = R.drawable.icon;
Notification notification = new Notification(icon,"Simple Notification",System.currentTimeMillis());
Intent toLaunch = new Intent(context, main.class);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, toLaunch, 0);
notification.setLatestEventInfo(context, "Emergency Alert", "Emergency call received from "+fetchName, contentIntent);

this.alert = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
}
else {
this.alert = Uri.parse(ringtone);
}
prev_ringtone = RingtoneManager.getActualDefaultRingtoneUri(context, RingtoneManager.TYPE_RINGTONE);
}
}
此错误仅发生在 TelephonyManager.CALL_STATE_IDLE 情况下。请提供任何解决此问题的方法。

尝试将实际异常添加到 Log.v() 调用中，因为它会将异常的完整详细信息转储到 LogCat： Log.v( "TAG", "Where it was caught", e);然后提供发生故障时被转储的堆栈跟踪的 LogCat。

我已经发布了堆栈跟踪，请看一下，如果你发现了什么，请告诉我
