Android GPS ACCURACY_HIGH导致力量关闭？

Question

我正在研究GPS部分和标准,我可以将精度设置为ACCURACY_FINE,ACCURACY_MEDIUM等.但是,由于某种原因,我不断得到一个力关闭错误如果我将它设置为ACCURACY_HIGH的标准.关于可能导致什么的任何想法？

继承我的清单,我非常确定一切正常,因为我可以使用不同的标准:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> 
<uses-permission android:name="android.permission.ACCESS_CHECKIN_PROPERTIES" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.VIBRATE" />

这是我的日志:

Answer 1

android Criteria有两组独立的精度常数.ACCURACY_FINE并且ACCURACY_COARSE用于一般位置,而ACCURACY_LOW,ACCURACY_MEDIUM和ACCURACY_HIGH"可用于水平,高度,速度或轴承精度." 如果您正在谈论一般GPS位置,您应该使用粗略或精细.

为了更清楚地阐明matt5784的答案,下面是一个如何使用新常量的示例:

    //All your normal criteria setup
    Criteria criteria = new Criteria();
    //Use FINE or COARSE (or NO_REQUIREMENT) here
    criteria.setAccuracy(Criteria.ACCURACY_FINE);
    criteria.setPowerRequirement(Criteria.POWER_LOW);
    criteria.setAltitudeRequired(true);
    criteria.setSpeedRequired(true);
    criteria.setCostAllowed(true);
    criteria.setBearingRequired(true);

    //API level 9 and up
    criteria.setHorizontalAccuracy(Criteria.ACCURACY_HIGH);
    criteria.setVerticalAccuracy(Criteria.ACCURACY_HIGH);
    criteria.setBearingAccuracy(Criteria.ACCURACY_LOW);
    criteria.setSpeedAccuracy(Criteria.ACCURACY_MEDIUM);
