Failed To Create Directory In Android Oreo (api 26)

I have already read the documentation for Android Oreo's Behavior and changes. I know there is different procedure to create file directory for Android Oreo (API 26) Code : File m

Solution 1:

Post Lollipop you have to ask for permission, you can look for the answer in this post here

publicbooleanisStoragePermissionGranted() {
    if (Build.VERSION.SDK_INT >= 23) {
        if (checkSelfPermission(android.Manifest.permission.WRITE_EXTERNAL_STORAGE)
                == PackageManager.PERMISSION_GRANTED) {
            Log.v(TAG,"Permission is granted");
            returntrue;
        } else {

            Log.v(TAG,"Permission is revoked");
            ActivityCompat.requestPermissions(this, newString[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
            returnfalse;
        }
    }
    else { //permission is automatically granted on sdk<23 upon installationLog.v(TAG,"Permission is granted");
        returntrue;
    }
}

Permission result callback:

@OverridepublicvoidonRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if(grantResults[0]== PackageManager.PERMISSION_GRANTED){
        Log.v(TAG,"Permission: "+permissions[0]+ "was "+grantResults[0]);
        //Create your Directory here
    }
}
