Android 6.0 multiple permissions

Question

I know that Android 6.0 has new permissions and I know I can call them with something like this

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

Today I saw a Google app which needs 3 permissions: contacts, sms and camera. It's making a page 1-3 and calls them all together at the same time to activate.

Can anybody tell me how I can call 4 permissions to activate at the same time like sms, camera, contacts and storage?

Example (forgot the name of the google app :( )
The app needs sms,contacts and camera

the app asked me (and made a dialog page1-3) activate sms, activate contacts and then camera. So this google app was calling all 3 required permissions together and my question is how can i achive the same ?

Answer 1

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();
            }
        }
    }

}

Answer 2

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

    private void requestUnGrantedPermissions(String[] permissions, int requestCode) {
        String[] unGrantedPermissions = findUnGrantedPermissions(permissions);
        if (unGrantedPermissions.length == 0) {
            mRequestPermissionListener.onSuccess();
            return;
        }
        ActivityCompat.requestPermissions(mActivity, unGrantedPermissions, requestCode);
    }

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

    private String[] findUnGrantedPermissions(String[] permissions) {
        List<String> unGrantedPermissionList = new ArrayList<>();
        for (String permission : permissions) {
            if (!isPermissionGranted(permission)) {
                unGrantedPermissionList.add(permission);
            }
        }
        return unGrantedPermissionList.toArray(new String[0]);
    }

    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
            @NonNull int[] grantResults) {
        if (requestCode == mRequestCode) {
            if (grantResults.length > 0) {
                for (int grantResult : grantResults) {
                    if (grantResult != PackageManager.PERMISSION_GRANTED) {
                        mRequestPermissionListener.onFailed();
                        return;
                    }
                }
                mRequestPermissionListener.onSuccess();
            } else {
                mRequestPermissionListener.onFailed();
            }
        }
    }

    public interface RequestPermissionListener {
        void onSuccess();

        void onFailed();
    }
}

Answer 3

Check the "Asking for multiple permissions at a time" section in this article:

Things you need to know about Android M permissions

It's very well explained, and may also touch other related topics you haven't think about.

Answer 4

Use helper like this (permissions names do not matter).

public class MyPermission {

private static final int PERMISSION_REQUEST_ALL = 127;
private MainActivity mMainActivity;

MyPermission(MainActivity mainActivity) {
    mMainActivity = mainActivity;
}

public static boolean hasPermission(String permission, Context context) {
    if (isNewPermissionModel()) {
        return (ActivityCompat.checkSelfPermission(context, permission) == PackageManager.PERMISSION_GRANTED);
    }
    return true;
}

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

private static boolean shouldShowRationale(Activity activity, String permission) {
    return isNewPermissionModel() && ActivityCompat.shouldShowRequestPermissionRationale(activity, permission);
}

private static boolean isNewPermissionModel() {
    return VERSION.SDK_INT > VERSION_CODES.LOLLIPOP_MR1;
}


/**

void checkAll() {
    //check dangerous permissions, make request if need (Android will ask only for the ones it needs)
    String[] PERMISSIONS = {
            permission.READ_CALENDAR,           
            permission.ACCESS_COARSE_LOCATION   
    };

    if (!hasPermissions(mMainActivity, PERMISSIONS)) {
        ActivityCompat.requestPermissions(mMainActivity, PERMISSIONS, PERMISSION_REQUEST_ALL);
    }
}

void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    if (requestCode == PERMISSION_REQUEST_ALL) {
        if (grantResults.length > 0) {
            //for not granted
            for (int i = 0; i < permissions.length; i++) {

                if (permissions[i].equals(permission.READ_CALENDAR)) {
                    if (grantResults[i] != PackageManager.PERMISSION_GRANTED) {
                        smartRequestPermissions(permission.READ_CALENDAR, R.string.permission_required_dialog_read_calendar);

                        smartRequestPermissions(permission.ACCESS_COARSE_LOCATION, R.string.permission_required_dialog_access_coarse_location);
                    }
                }

            }
        }
    }
}

private void smartRequestPermissions(final String permissionName, int permissionRequiredDialog) {
    if (shouldShowRationale(mMainActivity, permissionName)) {// If the user turned down the permission request in the past and chose the Don't ask again option in the permission request system dialog, this method returns false.

        //Show an explanation to the user with action
        mMainActivity.mSnackProgressBarManager.show(
                new SnackProgressBar(
                        SnackProgressBar.TYPE_ACTION, mMainActivity.getString(permissionRequiredDialog)
                )
                        .setAction("OK", new OnActionClickListener() {
                            @Override
                            public void onActionClick() {
                                checkAll();
                            }
                        })
                        .setSwipeToDismiss(true).setAllowUserInput(true)
                , MainActivity.SNACKBAR_WARNING_DURATION
        );

    } // else do nothing
}

}

Answer 5

I just use an array to achieved multiple requests, hope it helps someone. (Kotlin)

    // got all permission
    private fun requestPermission(){
        var mIndex: Int = -1
        var requestList: Array<String> = Array(10, { "" } )

        // phone call Permission
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
            mIndex ++
            requestList[mIndex] = Manifest.permission.CALL_PHONE
        }
        // SMS Permission
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED) {
            mIndex ++
            requestList[mIndex] = Manifest.permission.SEND_SMS
        }

        // Access photos Permission
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
            mIndex ++
            requestList[mIndex] = Manifest.permission.READ_EXTERNAL_STORAGE
        }

        // Location Permission
        if (ActivityCompat.checkSelfPermission(mContext, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED
                && ActivityCompat.checkSelfPermission(mContext, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            mIndex ++
            requestList[mIndex] = Manifest.permission.ACCESS_FINE_LOCATION
        }

        if(mIndex != -1){
            ActivityCompat.requestPermissions(this, requestList, PERMISSIONS_REQUEST_ALL)
        }
    }


    // permission response
    override fun onRequestPermissionsResult(requestCode: Int,
                                            permissions: Array<String>, grantResults: IntArray) {
        when (requestCode) {
            PERMISSIONS_REQUEST_ALL -> {
                // If request is cancelled, the result arrays are empty.
                if (grantResults.isNotEmpty() && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    // permission accept location
                    if (ContextCompat.checkSelfPermission(this,
                                    Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED) {
                        Log.d(TAG, "Phone Call permission accept.")
                    }

                    // permission accept location
                    if (ContextCompat.checkSelfPermission(this,
                                    Manifest.permission.SEND_SMS) == PackageManager.PERMISSION_GRANTED) {
                        Log.d(TAG, "SMS permission accept.")
                    }

                    // permission accept location
                    if (ContextCompat.checkSelfPermission(this,
                                    Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
                        Log.d(TAG, "SMS permission accept.")
                    }

                    // permission accept location
                    if (ContextCompat.checkSelfPermission(this,
                                    Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
                        Log.d(TAG, "Location permission accept.")
                    }

                } else {
                    Toast.makeText(mContext, "Permission Failed!", Toast.LENGTH_LONG).show()
                }
                return
            }
        }
    }

Answer 6

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 android.util.Log;

import java.util.ArrayList;
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) {
                for (int i = 0; i < permissions.length; i++)
                    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.
