仅限ACCESS_FINE_LOCATION权限错误模拟器

Question

我只在使用模拟器时遇到了一个奇怪的错误.我发现一个问题在9个月前有同样的问题,根本没有答案......

我正在使用谷歌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,一切都在我的手机上完美运行,只在使用模拟器时出现问题,我在我的iMac上尝试了不同的模拟器Windows机器.

我怀疑仿真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"/>

这里是异常触发的地方:

    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

我的猜测是你在Android 6.0+模拟器上运行它,你有targetSdkVersion23或更高.

在这种情况下,ACCESS_COARSE_LOCATION并ACCESS_FINE_LOCATION有部分在Android 6.0运行时许可制度.修改您的应用程序以参与此系统,或将您的应用程序targetSdkVersion降至23以下.

Answer 2

在Android 6.0(API级别23)中,用户在应用程序运行时向应用程序授予权限,而不是在安装应用程序时

如何检查您是否拥有权限:

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

如何申请所需的权限:

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.
}

如何访问请求的结果:

@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;
    }
}
}
