Android Requesting Multiple Permission at Runtime in Android 6.0 Marshmallow

In Android 6.0 Marshmallow User required to Grant the Permission At the time of running the Application Not when user is Installing the app.
Mainly There are two types of Permissions-:

• Normal Permissions
• Dangerous permissions

In Normal Permissions there is not any risk of user privacy Data. User only define the permissions in the manifest and system Grant the permission Automatically.

In Dangerous Permissions app can access Users's confidential data. So these permission needs the User's Approval before access it.

For More Information See Normal and Dangerous Permissions.

If your Application is running below 6.0 (below SDK 22)You don't need to Approval for Dangerous Permission else you need to Approve the permissions.

How To Check For Permission

If your app needs dangerous permission every time you need to check the permission, you are running the code.

1.Check If your application is Running Above or on Android 6.0 (SDK 23)

1 2 3 4 5 6 7

if (Build.VERSION.SDK_INT < 23) { //Do not need to check the permission } else { if (checkAndRequestPermissions()) { //If you have already permitted the permission } }

2.Create a static final constant to get recognize the request

private static final int MY_PERMISSIONS_REQUEST_ACCOUNTS = 1;

3.Check for the permission

1.For single Permission


private boolean checkAndRequestPermissions() {

//Here i am checking for account Permission 
    int accountPermission = ContextCompat.checkSelfPermission(this, 

Manifest.permission.GET_ACCOUNTS);
    List<String> listPermissionsNeeded = new ArrayList<>();

    if (accountPermission != PackageManager.PERMISSION_GRANTED) {
        listPermissionsNeeded.add(Manifest.permission.GET_ACCOUNTS);
    }
    if (!listPermissionsNeeded.isEmpty()) {
        ActivityCompat.requestPermissions(this, 

listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]), MY_PERMISSIONS_REQUEST_ACCOUNTS);
        return false;
    }

    return true;
}

2. For Multiple Permission

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

private boolean checkAndRequestPermissions() { int permissionCAMERA = ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA); int storagePermission = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE); List<String> listPermissionsNeeded = new ArrayList<>(); if (storagePermission != PackageManager.PERMISSION_GRANTED) { listPermissionsNeeded.add(Manifest.permission.READ_EXTERNAL_STORAGE); } if (permissionCAMERA != PackageManager.PERMISSION_GRANTED) { listPermissionsNeeded.add(Manifest.permission.CAMERA); } if (!listPermissionsNeeded.isEmpty()) { ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]), MY_PERMISSIONS_REQUEST_CAMERA); return false; } return true; }

4.Override this method 

1 2 3 4 5 6 7 8 9 10 11 12

@Override public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) { switch (requestCode) { case MY_PERMISSIONS_REQUEST_ACCOUNTS: if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) { //Permission Granted Successfully. Write working code here. } else { //You did not accept the request can not use the functionality. } break; } }

5.Enjoy the working code.
