Question

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。

我将请求权限放在onCreate中。在我提交请求权限申请后，崩溃后要求获得许可。

private boolean gpsInit() {
    mLocService = (LocationManager) 
   getSystemService(Context.LOCATION_SERVICE);
    if (mLocService != null) {
        mLocProvider = 
    mLocService.getProvider(LocationManager.GPS_PROVIDER);
        if (mLocProvider != null) {
            if (ActivityCompat.checkSelfPermission(this, 
  Manifest.permission.ACCESS_FINE_LOCATION) != 
      PackageManager.PERMISSION_GRANTED) {



                return true;
            }
            mLocService.addGpsStatusListener(this);
            if 
  (mLocService.isProviderEnabled(LocationManager.GPS_PROVIDER)) {

  gpsStatusTextView.setText(getString(R.string.status_gps_ready));
                return true;
            }
        }
    }


     gpsStatusTextView.setText
    (getString(R.string.status_gps_no_support));
    showDialog(NO_GPS_SUPPORT);
    Log.e(TAG, "Unable to get GPS PROVIDER");
    // todo disable gps controls into Preferences
    return false;
}

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>

甚至在我同意的情况下也获得许可错误
