Error: Client must have ACCESS_COARSE_LOCATION or

问题:

I use a module in a another app. Before I implement the module, I set it on API Level 23 (compile and target) like my Main Project This works fine, except this Error. The Pproblem is, that Google has changed the permissions management since marshmellow. Finaly now, i dont know how and where I should set the permissions.

This error I get when starting the application:

java.lang.SecurityException: Client must have ACCESS_COARSE_LOCATION or ACCESS_FINE_LOCATION permission to perform any operations location.

Could you please help me and explain briefly (what kind of code i need and where to insert) to avoid this error?

Could you please explain, what is the best way to manage the new Permission-System. Please explain to me in a simple way

回答1:

The coarse and fine location are considered 'dangerous' permissions. Therefore you have to ask for them on app launch(because I assume you have Android 6+):

public void checkPermission(){
    if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED ||
                       ContextCompat.checkSelfPermission(this,Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED
                    ){//Can add more as per requirement

                ActivityCompat.requestPermissions(this,
                        new String[]{Manifest.permission.ACCESS_FINE_LOCATION,Manifest.permission.ACCESS_COARSE_LOCATION},
                        123);
    }
}

And for calling:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M ) {
    checkPermission();
}

You can implement it anywhere, just remember to ask for permissions before you use something that requires them!

EDIT:

The stuff above should be called in an activity. This is on the onCreate method you posted above:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    /*
    This is called before initializing the map because the map needs permissions(the cause of the crash)
    */
    if (Build.VERSION.SDK_INT == Build.VERSION_CODES.M ) {
        checkPermission();
    }

    /*
     * Create a new location client, using the enclosing class to handle
     * callbacks.
     */
    mLocationClient = new LocationClient(this, this, this);

    // Create the LocationRequest object
    mLocationRequest = LocationRequest.create();
    // Use high accuracy
    mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    // Set the update interval to 5 seconds
    mLocationRequest.setInterval(UPDATE_INTERVAL);
    // Set the fastest update interval to 1 second
    mLocationRequest.setFastestInterval(FASTEST_INTERVAL);

    setContentView(R.layout.activity_main);
    .
    .
    .

That is the 'easy' way. YOu can force the user to it as well.

in onCreate call checkPermissions as normal.

However, the checkPermissions will now contain an intent. This is good to call on startup, because it will change the activity to this:

import android.Manifest;
import android.app.Activity;
import android.content.pm.PackageManager;
import android.os.Bundle;
import android.support.v4.app.ActivityCompat;
import android.support.v4.content.ContextCompat;
import android.view.View;
import android.widget.Button;


public class Permissions extends Activity implements View.OnClickListener{
    /**
     * This will handle permissions asking
     */
    Button button;
    //handles ask permissions/continue
    boolean completed = false;
    public void onCreate(Bundle sis){
        super.onCreate(sis);
        /**
         * I'm not going to create the layout for you, but you essentially need two things:
         * a TextView
         * a Button
         *
         * The TextView will explain **why** you need the permissions, while the button
         * will be pressed by the user to ask the permissions. No need to call the textview
         * inside this class
         */
        setContentView(R.layout.yourlayout);
        button = (Button) findViewById(R.id.button);

    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.button:
                if(!completed)
                    askPermissions();
                else{
                    //start the main activity
                }
                break;
        }
    }


    public void askPermissions(){
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED ||
                ContextCompat.checkSelfPermission(this,Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED
                ){//Can add more as per requirement

            ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.ACCESS_FINE_LOCATION,Manifest.permission.ACCESS_COARSE_LOCATION},
                    123);
        }else if(ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED &&
                ContextCompat.checkSelfPermission(this,Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED
                ){
            completed = true;
            button.setText("Permissions supplied. Press to continue");
        }

    }
}

And the new checkPermission in the activity:

public void checkPermission(){
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED ||
                           ContextCompat.checkSelfPermission(this,Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED
                        ){//Can add more as per requirement

       //start an intent to the class above. Do this because the app does not have enough permissions

    }
}

This will force the user to allow access to the permissions othervise he/she will not get access to the app. If the permissions are denied, the user will not get access because it will crash the app(you can write that in the explanative textview in the layout.

So, I'm not going to supply you with a layout, because it is really up to you. But you need two basic things:

  • Button - the user presses this after reading the textview(intended, you cannot force the user to read it) and when pressing the button it will either ask permissions or redirect to
  • TextView - Will explain what permissions you are asking for and why you need them

This system is very smart because if all permissions are supplied, the screen isn't called. Keep in mind though, the Build-VERSION.SDK_INT >= Build.VERSION_CODES.M is very important to have, othervise this will cause errors(because it asks for permissions on platforms that does not support it)
