即使我将请求权限放入onCreate中,我也会收到位置权限错误。在我提交请求权限申请后,崩溃后要求获得许可。

private boolean gpsInit() {

在Oncreate内部:

    if (ContextCompat.checkSelfPermission(getApplicationContext(), Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            requestPermissions(new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, REQUEST_PERMISSION_LOCATION);
        }
    } else {
        // We have already permission to use the location
    }

在此行出现错误
   mLocProvider = mLocService.getProvider(LocationManager.GPS_PROVIDER);

我想要的是应用程序应在午餐时征求许可

确保您在清单中添加权限

如果没有,请在清单文件中写入以下内容。

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