I bought a used Note4 & since receiving it, there's this "Smart Peel remote"
app in it which I've uninstalled it (via PlayStore) : however, the next day,
this app will pop up & when I go to PlayStore, could see that it's installed.

Each time after clicking "Uninstall" for this app in PlayStore, the "Uninstall"
button will turn to "Update" button.

What must I do so that this app doesn't come back (disruptive pop-ups)

The earlier expert suggest disabling it but how is this done?

How to send message in whatsapp without open whatsapp apps using android?
I am looking for a lock that runs on batteries and connects to wifi, not Bluetooth for controlled entry access via my smartphone.  It needs to work outside and will be used to control access to a gate.

Assistance is greatly appreciated.

I wonder if this combination using the relay solution is reasonable?

How to identify editing on AMR file? Is there any softwares for that the phone call recorded was edited or not!
I'm using Android Studio and I would like to be able to pickup am image from the gallery, resize it and make it fit inside a rounded square (of about 300x300px) by maintening the correct aspect ratio. At the moment, I'm able to resize it and display it as a circle with this code:

FixBitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
                bitmap_to_save = scaleBitmapAndKeepRation(FixBitmap, 320, 320);

                RoundedBitmapDrawable roundDrawable = RoundedBitmapDrawableFactory.create(getResources(), bitmap_to_save);

Open in new window

However, I would like to know if it is possible to make the bitmap look like my attached image. Moreover, it would be important for me to resize the image without losing the original aspect ratio.

It is not exactly a well square rounded figure, so I'm not sure that it is possible to do it in Android.

I hope you can help me, thanks!

EDIT: I'm using Picasso library for the moment, and it seems to work. Anyway, I would like to keep always the same picture size (300x300 px) and the aspect ratio. How can I do it?

We want to offer our customers the possibility to download their APN settings trough a browser.
Apple has a Configuration Utility, that works fine.

It seems to be an XML like binary, that includes the details of the APN settings.
When accessing this file in the default (Safari) browser, it asks if you wish to load the config. If so, it loads the APN settings into the phone.

Does Android offer the same option?
I've been trying to fix this for days now. Using Xamarin and Visual Studio, I deleted the asset catalogs/media folder then I used app icon set creator to create the icons. I then went into info.plist under visual assets and hit add catalog, then dragged the icons into the slots.

No matter how many times I try this I get the same error.

Since this is xamarin, I was told I have to create an IPA file and upload using ApplicationUploader.  The file uploads but then I get an email from Apple with a build file error shown above.

Does anyone know how to fix this?

My company is developing a mobile App, and it is advised to block Rooted machine from using it.
The Rooted detection mechanism works, but has false positives on non-Rooted Miui Xiaomi mobiles, because they seems to have some Root-bundled function even it is new.

Is there any way to distinguish a Rooted and non-Rooted Xiaomi? to check the bootloader lock or unlock status? Grateful if any can share me some source code for the check.

Thanks a lot.
