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

答案 0 :(得分:4)
我认为您的问题是,当您收到CALL_STATE_IDLE时,未设置incomingNumber变量,因为没有活动或振铃呼叫,因此没有与当前电话状态关联的电话号码。然后,您正在进行失败的联系人查找,因为您未在查询中包含有效的电话号码。
因此,当您实际上没有要搜索的电话号码时,您正试图查找联系人。
答案 1 :(得分:0)
啊我以前见过这个错误,
您的URI格式错误,因为您将其设置为默认铃声
prev_ringtone = RingtoneManager.getActualDefaultRingtoneUri(context, RingtoneManager.TYPE_RINGTONE);
但是,默认铃声尚未设置,因此您将返回空字符串/ null或其他错误。
