I have read some question's answer on stackoverflow about how to prevent an app from being shared after downloading it form Google Play Store. Such as:

Adding Google Play Licensing: How to secure an Android app against sharing apps like ShareIT & more?

Adding Google Play Licensing and In-app Billing: How to prevent android app being downloaded outside google play

In some places, I have also seen Google Play Licensing can be cracked with some third party softwares or rooting the device. Such a video's link of youtube: How To Remove License Verification From All Android Apps

However, the video was uploaded three years ago, so I don't know if it will work in 2020 or there might be other new ways of doing it.

So, is it a better option to publish an app with in-app billing/purchase to avoid piracy or it also have some drawbacks?

I want to find get the location of files by just typing the file name and the correct extension So in python we normally do this by importing the os module and then typing -:

os.path.abspath("file name.extension")

But my program is not giving me the correct file location I have written this code-:

I am developing a sharing app similar to Shareit, Xender. I want to show all the thumbnails of videos in a simple gridview but loading thumbnails takes a lot of time especially if I have more than a 1000 - 2000 videos. So, I made a program to load each thumbnail on a new thread if it hasn't been loaded and then notify the base adapter.

I'm trying to set up a share button on my app. The button is supposed to take a screenshot of a particular list view, and then allow the user to share this image via whatever means they want. To do this, I created three methods:

1. Take the screenshot
2. Save it in my storage
3. Share it to the user.

To do this I've written the following code:

Well, I have built an app to store values on a remote database. It works!! I didn't use an emulator for testing instead I used my own phone. Now the problem is that on my phone, it works perfectly...no issues but when I installed it on another phone, the app doesn't connect to the internet. I have included internet permission in android manifest.xml.

I have tried these but didn't work:

1. Building apk and installing in the new phone.
2. Compiling directly to the new phone.
3. Sending the apk from old phone to new phone via shareit.
4. Creating a signed apk and installing.
5. Checked via wifi and mobile data (NOTE: BOTH WIFI AND MOBILE DATA WORKS IN OLD PHONE).
6. Checked android compatibility: supports up to android 10.

*I added error messages for try...catch blocks in form of toasts for the user to know what's the issue. and the catch exception for no internet returns connection problem. I'm getting that error message.

As I researched, I got to know that internet permission is categorized as normal permission which is not prompted to the user upon installation.

I built a second dummy app: Same issue with it... compiled directly to new phone but didn't work...it works in old phone...

Old phone: Samsung J7 Prime with Android 8.1 New Phone: Samsung J7 Pro with Android 9

Any idea or suggestion will be gladly helpful... Thank you!
