Java 请求服务内部的位置权限

我正在使用服务获取位置数据，此服务在我的应用程序在活动上运行时启动，我需要该活动来请求权限

所以基本上这是我的服务（效果很好）

我从这里开始

package com.example.afcosta.inesctec.pt.android;

import android.Manifest;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.support.annotation.NonNull;
import android.support.v4.app.ActivityCompat;
import android.support.v4.content.ContextCompat;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;

import com.example.afcosta.inesctec.pt.android.services.GoogleLocation;

public class LocationPermission extends AppCompatActivity {

    public static final int REQ_PERMISSION = 99;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        askPermission();
        Intent i = new Intent(this,Login.class);
        startActivity(i);
    }

    // PEDIDO DE PERMISSÃO
    private void askPermission() {
        checkLocationPermission();
    }

    public static final int MY_PERMISSIONS_REQUEST_LOCATION = 99;

    public boolean checkLocationPermission() {
        if (ContextCompat.checkSelfPermission(this,
                Manifest.permission. ACCESS_FINE_LOCATION)
                != PackageManager.PERMISSION_GRANTED) {

            // Should we show an explanation?
            if (ActivityCompat.shouldShowRequestPermissionRationale(this,
                    Manifest.permission. ACCESS_FINE_LOCATION)) {

                // Show an explanation to the user *asynchronously* -- don't block
                // this thread waiting for the user's response! After the user
                // sees the explanation, try again to request the permission.
                new AlertDialog.Builder(this)
                        .setTitle("Partilhar localização")
                        .setMessage("Permitir a partilha de dados sobre a sua localização?")
                        .setPositiveButton("ok", new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialogInterface, int i) {
                                //Prompt the user once explanation has been shown
                                ActivityCompat.requestPermissions(LocationPermission.this,
                                        new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
                                        MY_PERMISSIONS_REQUEST_LOCATION);
                            }
                        })
                        .create()
                        .show();


            } else {
                // No explanation needed, we can request the permission.
                ActivityCompat.requestPermissions(this,
                        new String[]{Manifest.permission. ACCESS_FINE_LOCATION},
                        MY_PERMISSIONS_REQUEST_LOCATION);
            }
            return false;
        } else {
            startService(new Intent(this, GoogleLocation.class));
            return true;
        }
    }

    @Override
    public void onRequestPermissionsResult(int requestCode,
                                           String permissions[], int[] grantResults) {
        switch (requestCode) {
            case MY_PERMISSIONS_REQUEST_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
                    // location-related task you need to do.
                    if (ContextCompat.checkSelfPermission(this,
                            Manifest.permission. ACCESS_FINE_LOCATION)
                            == PackageManager.PERMISSION_GRANTED) {

                        startService(new Intent(this, GoogleLocation.class));
                    }

                } else {

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

                }
                return;
            }

        }
    }
}

问题是，当他第一次运行应用程序时，我需要请求权限，或者他禁用了位置。这永远不会发生

我应该在用户授予权限后启动服务

有什么帮助吗

谢谢

您可以通过以下方式在运行时请求任何权限：

if (ContextCompat.checkSelfPermission(context, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
    if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION)) {

    } else {
        ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, RC_ACCESS_FINE_LOCATION);
    }
}

您可以通过以下方式获得结果：

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case RC_ACCESS_FINE_LOCATION: {

        }
    }
}

应在启动服务之前请求许可

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case RC_ACCESS_FINE_LOCATION: {

        }
    }
}

@Override
  protected Boolean processInBackground(Void... params) {
      PermissionResponse response = PermissionEverywhere.getPermission(getApplicationContext(), 
      new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
              REQ_CODE,
              "Notification title", 
              "This app need external permisison", 
              R.launcher)
              .call();

      boolean isGranted = response.isGranted();

      if(isGrante){


        // here do your stuff
      }
  }
