Android 6.0 multiple permissions

Question

Just include all 4 permissions in the ActivityCompat.requestPermissions(...) call and Android will automatically page them together like you mentioned.

I have a helper method to check multiple permissions and see if any of them are not granted.

public static boolean hasPermissions(Context context, String... permissions) {
    if (context != null && permissions != null) {
        for (String permission : permissions) {
            if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
                return false;
            }
        }
    }
    return true;
}

Or in Kotlin:

fun hasPermissions(context: Context, vararg permissions: String): Boolean = permissions.all {
    ActivityCompat.checkSelfPermission(context, it) == PackageManager.PERMISSION_GRANTED
}

Then just send it all of the permissions. Android will ask only for the ones it needs.

// The request code used in ActivityCompat.requestPermissions()
// and returned in the Activity's onRequestPermissionsResult()
int PERMISSION_ALL = 1; 
String[] PERMISSIONS = {
  android.Manifest.permission.READ_CONTACTS, 
  android.Manifest.permission.WRITE_CONTACTS, 
  android.Manifest.permission.WRITE_EXTERNAL_STORAGE, 
  android.Manifest.permission.READ_SMS, 
  android.Manifest.permission.CAMERA
};

if (!hasPermissions(this, PERMISSIONS)) {
    ActivityCompat.requestPermissions(this, PERMISSIONS, PERMISSION_ALL);
}

Here is detailed example with multiple permission requests:-

The app needs 2 permissions at startup . SEND_SMS and ACCESS_FINE_LOCATION (both are mentioned in manifest.xml).

I am using Support Library v4 which is prepared to handle Android pre-Marshmallow and so no need to check build versions.

As soon as the app starts up, it asks for multiple permissions together. If both permissions are granted the normal flow goes.

public static final int REQUEST_ID_MULTIPLE_PERMISSIONS = 1;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    if(checkAndRequestPermissions()) {
        // carry on the normal flow, as the case of  permissions  granted.
    }
}

private  boolean checkAndRequestPermissions() {
    int permissionSendMessage = ContextCompat.checkSelfPermission(this,
            Manifest.permission.SEND_SMS);
    int locationPermission = ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION);
    List<String> listPermissionsNeeded = new ArrayList<>();
    if (locationPermission != PackageManager.PERMISSION_GRANTED) {
        listPermissionsNeeded.add(Manifest.permission.ACCESS_FINE_LOCATION);
    }
    if (permissionSendMessage != PackageManager.PERMISSION_GRANTED) {
        listPermissionsNeeded.add(Manifest.permission.SEND_SMS);
    }
    if (!listPermissionsNeeded.isEmpty()) {
        ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]),REQUEST_ID_MULTIPLE_PERMISSIONS);
        return false;
    }
    return true;
}

ContextCompat.checkSelfPermission(), ActivityCompat.requestPermissions(), ActivityCompat.shouldShowRequestPermissionRationale() are part of support library.

In case one or more permissions are not granted, ActivityCompat.requestPermissions() will request permissions and the control goes to onRequestPermissionsResult() callback method.

You should check the value of shouldShowRequestPermissionRationale() flag in onRequestPermissionsResult() callback method.

There are only two cases:--

Case 1:-Any time user clicks Deny permissions (including the very first time), it will return true. So when the user denies, we can show more explanation and keep asking again

Case 2:-Only if user select “never asks again” it will return false. In this case, we can continue with limited functionality and guide user to activate the permissions from settings for more functionalities, or we can finish the setup, if the permissions are trivial for the app.

CASE -1

CASE-2

                perms.put(Manifest.permission.ACCESS_FINE_LOCATION, PackageManager.PERMISSION_GRANTED);

            }

        }


    }
}

}

It's easy, do this way

private static final int REQUEST_READ_PHONE_STATE = 110 , REQUEST_ACCESS_FINE_LOCATION = 111, REQUEST_WRITE_STORAGE = 112;

In your onCreate

 //request permission
    boolean hasPermissionPhoneState = (ContextCompat.checkSelfPermission(getApplicationContext(),
            Manifest.permission.READ_PHONE_STATE) == PackageManager.PERMISSION_GRANTED);
    if (!hasPermissionPhoneState) {
        ActivityCompat.requestPermissions(LoginActivity.this,
                new String[]{Manifest.permission.READ_PHONE_STATE},
                REQUEST_READ_PHONE_STATE);
    }

    boolean hasPermissionLocation = (ContextCompat.checkSelfPermission(getApplicationContext(),
            Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED);
    if (!hasPermissionLocation) {
        ActivityCompat.requestPermissions(LoginActivity.this,
                new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
                REQUEST_ACCESS_FINE_LOCATION);
    }

    boolean hasPermissionWrite = (ContextCompat.checkSelfPermission(getApplicationContext(),
            Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED);
    if (!hasPermissionWrite) {
        ActivityCompat.requestPermissions(LoginActivity.this,
                new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
                REQUEST_WRITE_STORAGE);
    }

Then check result

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    switch (requestCode)
    {
        case REQUEST_READ_PHONE_STATE: {
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
            {
                Toast.makeText(LoginActivity.this, "Permission granted.", Toast.LENGTH_SHORT).show();
                //reload my activity with permission granted or use the features what required the permission
                finish();
                startActivity(getIntent());
            } else
            {
                Toast.makeText(LoginActivity.this, "The app was not allowed to get your phone state. Hence, it cannot function properly. Please consider granting it this permission", Toast.LENGTH_LONG).show();
            }
        }
        case REQUEST_ACCESS_FINE_LOCATION: {
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
            {
                Toast.makeText(LoginActivity.this, "Permission granted.", Toast.LENGTH_SHORT).show();
                //reload my activity with permission granted or use the features what required the permission
                finish();
                startActivity(getIntent());
            } else
            {
                Toast.makeText(LoginActivity.this, "The app was not allowed to get your location. Hence, it cannot function properly. Please consider granting it this permission", Toast.LENGTH_LONG).show();
            }
        }

        case REQUEST_WRITE_STORAGE: {
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
            {
                Toast.makeText(LoginActivity.this, "Permission granted.", Toast.LENGTH_SHORT).show();
                //reload my activity with permission granted or use the features what required the permission
                finish();
                startActivity(getIntent());
            } else
            {
                Toast.makeText(LoginActivity.this, "The app was not allowed to write to your storage. Hence, it cannot function properly. Please consider granting it this permission", Toast.LENGTH_LONG).show();
            }
        }
    }

}

My approach is based on Nicks' answer and hopefully is a bit more usable for multiple (as many as needed, not only two) permissions. It suggests adding single-responsibility PermissionsHelper class:

import android.app.Activity;
import android.app.AlertDialog;
import android.content.pm.PackageManager;
import android.support.v4.app.ActivityCompat;
import android.support.v4.content.ContextCompat;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class PermissionsHelper {

private static final int REQUEST_ID_MULTIPLE_PERMISSIONS = 100; // any code you want.

public void checkAndRequestPermissions(Activity activity, String... permissions) {
    List<String> listPermissionsNeeded = new ArrayList<>();
    for (String permission : permissions) {
        if (ContextCompat.checkSelfPermission(activity, permission) != PackageManager.PERMISSION_GRANTED) {
            listPermissionsNeeded.add(permission);
        }
    }
    if (!listPermissionsNeeded.isEmpty()) {
        ActivityCompat.requestPermissions(activity, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]), REQUEST_ID_MULTIPLE_PERMISSIONS);
    }
}

public void onRequestPermissionsResult(Activity activity, int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case REQUEST_ID_MULTIPLE_PERMISSIONS: {
            Map<String, Integer> perms = new HashMap<>();

            for (String permission : permissions) {
                perms.put(permission, PackageManager.PERMISSION_GRANTED);
            }

            if (grantResults.length > 0) {

                    perms.put(permissions[i], grantResults[i]);

                boolean allPermissionsGranted = true;
                for (String permission1 : permissions) {
                    allPermissionsGranted = allPermissionsGranted && (perms.get(permission1) == PackageManager.PERMISSION_GRANTED);
                }

                if (allPermissionsGranted) {
                    Log.d(PermissionsHelper.class.getSimpleName(), "onRequestPermissionsResult: all permissions granted");
                } else {
                    for (String permission2 : perms.keySet())
                        if (perms.get(permission2) == PackageManager.PERMISSION_GRANTED)
                            perms.remove(permission2);

                    StringBuilder message = new StringBuilder("The app has not been granted permissions:\n\n");
                    for (String permission : perms.keySet()) {
                        message.append(permission);
                        message.append("\n");
                    }
                    message.append("\nHence, it cannot function properly." +
                            "\nPlease consider granting it this permission in phone Settings.");

                    AlertDialog.Builder builder = new AlertDialog.Builder(activity);
                    builder.setTitle(R.string.permission_required)
                            .setMessage(message)
                            .setPositiveButton(android.R.string.ok, (dialog, id) -> dialog.cancel());
                    AlertDialog alert = builder.create();
                    alert.show();
                }
            }
        }
    }
}

}

If one or several required permissions have not been granted by user, the detailed AlertDialog message will be shown to him.

Example of usage in Activity:

private PermissionsHelper permissionsHelper;

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

    checkPermissions();

    //any other code
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    permissionsHelper.onRequestPermissionsResult(this, requestCode, permissions, grantResults);
}

private void checkPermissions() {
    permissionsHelper = new PermissionsHelper();
    permissionsHelper.checkAndRequestPermissions(this,
            Manifest.permission.READ_EXTERNAL_STORAGE,
            Manifest.permission.ACCESS_FINE_LOCATION,
            Manifest.permission.ACCESS_COARSE_LOCATION);
}

Hope that this will be useful for someone.

My handler class for request multiple permissions. You can check the full using here

public class RequestPermissionHandler {
    private Activity mActivity;
    private RequestPermissionListener mRequestPermissionListener;
    private int mRequestCode;

    public void requestPermission(Activity activity, @NonNull String[] permissions, int requestCode,
            RequestPermissionListener listener) {
        mActivity = activity;
        mRequestCode = requestCode;
        mRequestPermissionListener = listener;

        if (!needRequestRuntimePermissions()) {
            mRequestPermissionListener.onSuccess();
            return;
        }
        requestUnGrantedPermissions(permissions, requestCode);
    }

    private boolean needRequestRuntimePermissions() {

    }

    private void requestUnGrantedPermissions(String[] permissions, int requestCode) {
        String[] unGrantedPermissions = findUnGrantedPermissions(permissions);

            return;
        }
        ActivityCompat.requestPermissions(mActivity, unGrantedPermissions, requestCode);
    }

    private boolean isPermissionGranted(String permission) {
        return ActivityCompat.checkSelfPermission(mActivity, permission)
                == PackageManager.PERMISSION_GRANTED;
    }

                unGrantedPermissionList.add(permission);
            }
        }
        return unGrantedPermissionList.toArray(new String[0]);
    }

    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,

                        return;
                    }
                }
                mRequestPermissionListener.onSuccess();
            } else {
                mRequestPermissionListener.onFailed();
            }
        }
    }

    public interface RequestPermissionListener {
