ACCESS_FINE_LOCATION 权限错误仅限模拟器

Question

我在仅使用模拟器时遇到奇怪的错误。我在 9 个月前发现了一个有同样问题的问题，但根本没有答案...

我正在使用 google 播放服务位置来获取我的应用程序中的位置，我确定我的清单权限并且一切都在我的 phone 上完美运行，问题发生在使用仅限模拟器，我在 iMac 和 Windows 机器上尝试了不同的模拟器。

我怀疑模拟器不支持这个基本功能！

这是我的清单代码：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.orderme.ordermeandroid" >
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

这是触发异常的地方：

    LocationRequest mLocationRequest = new LocationRequest();
    mLocationRequest.setInterval(10000);
    mLocationRequest.setFastestInterval(5000);
    mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    LocationServices.FusedLocationApi.requestLocationUpdates(googleApiClient,mLocationRequest,this);

堆栈跟踪：

Answer 1

您无法从模拟器获取当前位置。但是您可以模拟它来测试您的代码。 Here 你可以找到如何模拟。

编辑 1： 有注释here

Note: If you are using both NETWORK_PROVIDER and GPS_PROVIDER, then you need to request only the ACCESS_FINE_LOCATION permission, because it includes permission for both providers. (Permission for ACCESS_COARSE_LOCATION includes permission only for NETWORK_PROVIDER.)

您应该只使用 ACCESS_FINE_LOCATION 权限。也许这有帮助。

Answer 2

我的猜测是您在 Android 6.0+ 模拟器上运行并且您的 targetSdkVersion 为 23 或更高。

在这种情况下，ACCESS_COARSE_LOCATION 和 ACCESS_FINE_LOCATION 是 the Android 6.0 runtime permission system 的一部分。要么修改您的应用程序以加入该系统，要么将您的 targetSdkVersion 降到 23 以下。

Answer 3

在 Android 6.0（API 级别 23）中，用户在应用运行时向应用授予权限，而不是在他们安装应用时

如何检查您是否有权限：

// Assume thisActivity is the current activity
int permissionCheck = ContextCompat.checkSelfPermission(thisActivity,
        android.Manifest.permission.ACCESS_FINE_LOCATION);

如何请求您需要的权限：

if (ContextCompat.checkSelfPermission(thisActivity,
            Manifest.permission.ACCESS_FINE_LOCATION)
    != PackageManager.PERMISSION_GRANTED) {

    ActivityCompat.requestPermissions(thisActivity,
            new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
            MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION);

    // MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION is an
    // app-defined int constant. The callback method gets the
    // result of the request.
}

如何访问请求结果：

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
    case MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION: {
        // If request is cancelled, the result arrays are empty.
        if (grantResults.length > 0
            && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

            // permission was granted, yay! Do the task you need to do.

        } else {

            // permission denied, boo! Disable the functionality that depends on this permission.
        }
        return;
    }
}
}

Answer 4

此问题是由 Android 6.0 的一项新功能引起的。希望它的工作...

从 Android 6.0（API 级别 23）开始，用户在应用运行时向应用授予权限，而不是在安装应用时。

http://developer.android.com/training/permissions/requesting.html

为了解决未明确授予权限时的问题，我进行了检查以包装位置服务调用（根据 Google 文档，稍作修改）。

int permissionCheck = ContextCompat.checkSelfPermission(context, Manifest.permission.ACCESS_FINE_LOCATION);

if (permissionCheck == PackageManager.PERMISSION_GRANTED) {
    //Execute location service call if user has explicitly granted ACCESS_FINE_LOCATION..
}

Google 文档还逐步介绍了如何请求所需的权限。

Answer 5

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

有时清单中缺少授予 ACCESS_FINE_LOCATION 权限的行。所以你需要在清单中提到它。

我这样做了，我的问题就解决了。

这通常是因为我们在清单中授予了权限，所以应用程序会产生问题，因为不允许它访问权限并且文件会崩溃。

<?xml version="1.0" encoding="utf-8"?>


<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme" >
    <activity android:name=".MainActivity" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>
