Multiple permissions and ask again on denial

Question

I want to make an app which asks user for two permissions- READ_CALL_LOG and READ_CONTACTS. Now if the user denies READ_CALL_LOG then it should show a warning which should have a button that asks the user to grant permission again. When that button is clicked the user is asked again to grant READ_CALL_LOG permission. When the user grants READ_CALL_LOG permission he is taken to READ_CONTACTS permission. If he denies READ_CONTACTS permission then again it should show a warning which should have a button that asks the user to grant permission again. When that button is clicked the user is asked again to grant READ_CONTACTS permission. I don't want the user to be navigated to Settings if he denies. I have tried this code:

public class MainActivity extends AppCompatActivity

{

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    /*if(((ContextCompat.checkSelfPermission(MainActivity.this,Manifest.permission.READ_CALL_LOG)== PackageManager.PERMISSION_DENIED)&&(ContextCompat.checkSelfPermission(MainActivity.this,Manifest.permission.READ_CONTACTS)== PackageManager.PERMISSION_DENIED))||((ContextCompat.checkSelfPermission(MainActivity.this,Manifest.permission.READ_CALL_LOG)!= PackageManager.PERMISSION_GRANTED)&&(ContextCompat.checkSelfPermission(MainActivity.this,Manifest.permission.READ_CONTACTS)!= PackageManager.PERMISSION_GRANTED)))
    requestPermission();*/

    if(ContextCompat.checkSelfPermission(MainActivity.this,Manifest.permission.READ_CALL_LOG)== PackageManager.PERMISSION_DENIED)
    {
        requestCallLogsPermission();
    }

    if(ContextCompat.checkSelfPermission(MainActivity.this,Manifest.permission.READ_CONTACTS)== PackageManager.PERMISSION_DENIED)
    {
        requestContactPermission();
    }

}

private void requestCallLogsPermission()
{
    if(ContextCompat.checkSelfPermission(MainActivity.this,Manifest.permission.READ_CALL_LOG)!= PackageManager.PERMISSION_GRANTED)
    {
        Dexter.withActivity(MainActivity.this).withPermission(Manifest.permission.READ_CALL_LOG).withListener(new PermissionListener()
        {
            @Override
            public void onPermissionGranted(PermissionGrantedResponse response)
            {
                Toast.makeText(MainActivity.this, "Call Logs Permission is granted !", Toast.LENGTH_SHORT).show();
                //if((ContextCompat.checkSelfPermission(MainActivity.this,Manifest.permission.READ_CONTACTS)== PackageManager.PERMISSION_DENIED)||ContextCompat.checkSelfPermission(MainActivity.this,Manifest.permission.READ_CONTACTS)!= PackageManager.PERMISSION_GRANTED)
                requestContactPermission();
            }

            @Override
            public void onPermissionDenied(PermissionDeniedResponse response)
            {
                    AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
                    builder.setTitle("Permissions");
                    builder.setMessage("Permission is required");
                    builder.setCancelable(false);
                    builder.setPositiveButton("Understood, I am ready to give the permissions required", new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which)
                        {
                            requestCallLogsPermission();
                        }
                    }).show();

            }

            @Override
            public void onPermissionRationaleShouldBeShown(PermissionRequest permission, PermissionToken token) {
                token.continuePermissionRequest();
            }
        }).check();
    }
}

private void requestContactPermission()
{
    Dexter.withActivity(MainActivity.this).withPermission(Manifest.permission.READ_CONTACTS).withListener(new PermissionListener() {

                Toast.makeText(MainActivity.this, "Read Contacts Permission is granted !", Toast.LENGTH_SHORT).show();
            }

            @Override

                AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);

                builder.setMessage("Permission is required");
                builder.setCancelable(false);
                builder.setPositiveButton("Understood, I am ready to give the permissions required", new DialogInterface.OnClickListener() {
                    @Override

                        requestCallLogsPermission();
                    }
                }).show();

            }

            @Override
            public void onPermissionRationaleShouldBeShown(PermissionRequest permission, PermissionToken token) {
                token.continuePermissionRequest();
            }
        }).check();

Answer 1

You can try this method:

1.) Setting up permissions:

String[] permissions = {
        android.Manifest.permission.READ_EXTERNAL_STORAGE,
        Manifest.permission.CAMERA
}; // Use the permission you need

2.) -Check and request if not already permitted:

onCreate() {
    if (!checkPermissions()){
        ActivityCompat.requestPermissions(this, permissions, 1);
    }
}

private boolean checkPermissions() {
    for (String permission: permissions){
        if (ActivityCompat.checkSelfPermission(this, permission) != PackageManager.PERMISSION_GRANTED){
            return false;
        }
    }
    return true;
}

3.) Check for denial status and keep asking till all permissions are granted:

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

    boolean allGranted = true;

    for (int result: grantResults){
        if (result == PackageManager.PERMISSION_DENIED){
            allGranted = false;
        }
    }

    if (!allGranted){
        if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.CAMERA) ||
                ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.READ_EXTERNAL_STORAGE))
        {
            // Here do whatever you want once the user denies
            final String[] mPermissions = permissions;

            AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this).create();
            alertDialog.setTitle("Alert!");
            alertDialog.setMessage("Please allow the permissions!");
            alertDialog.setCancelable(false);
            alertDialog.setButton(AlertDialog.BUTTON_NEUTRAL, "OK",
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
                            ActivityCompat.requestPermissions((MainActivity.this), mPermissions, 1);
                            dialog.dismiss();
                        }
                    });
            alertDialog.show();
        }
        else {
            Log.d(TAG, "PERMANENTLY DENIED");

            AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this).create();
            alertDialog.setTitle("Alert!");
            alertDialog.setMessage("All permissions are necessary for app to run. Goto settings and grant them.");
            alertDialog.setCancelable(false);
            alertDialog.setButton(AlertDialog.BUTTON_NEUTRAL, "OK",
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
                            startActivity(new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS, Uri.parse("package:" + BuildConfig.APPLICATION_ID)));
                            dialog.dismiss();
                        }
                    });
            alertDialog.show();

        }
    }

}
