Android marshmallow request permission?

Question

I am currently working on an application that requires several \"dangerous\" permissions. So I tried adding \"ask for permission\" as required in Android Marshmallow(API Lev

It may be a cleaner way. Add all your permissions in an array like

private static final String[] INITIAL_PERMS={
            android.Manifest.permission.ACCESS_FINE_LOCATION,
            android.Manifest.permission.ACCESS_COARSE_LOCATION
    };
    private static final int INITIAL_REQUEST=1337;

Whatever your permision is create method for each permision

@RequiresApi(api = Build.VERSION_CODES.M)
private boolean canAccessFineLocation() {
    return(hasPermission(Manifest.permission.ACCESS_FINE_LOCATION));
}

@RequiresApi(api = Build.VERSION_CODES.M)
private boolean canAccessCoarseLocation() {
    return(hasPermission(Manifest.permission.ACCESS_COARSE_LOCATION));
}

@RequiresApi(api = Build.VERSION_CODES.M)
private boolean hasPermission(String perm) {
    return(PackageManager.PERMISSION_GRANTED == checkSelfPermission(perm));
}

Call this method in onCreate

 if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M){
      if(!canAccessCoarseLocation() || !canAccessFineLocation()){
            requestPermissions(INITIAL_PERMS, INITIAL_REQUEST);
        }
 }

Now override onRequestPermissionsResult

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

    if(requestCode == INITIAL_REQUEST){
        if (canAccessFineLocation() && canAccessCoarseLocation())  {
            //call your method
        }
        else {
            //show Toast or alert that this permissions is neccessary
        }
    }
}
