Google is not fair Good day. I want to ask a non-standard question for Android developers. I have an app that pays to complete tasks. (installing other applications and watching ads) But Google is constantly removing it, under the pretext of its policy. (you cannot motivate users to download applications) However, Google Play is full of such applications, they even have millions of downloads. What can be done? How to publish such an application.

Android RecyclerView NotifyDataSetChanged with LiveData When instantiating the ListAdapter for my RecyclerView, I call: viewModel.currentList.observe(viewLifecycleOwner){ adapter.submitList(it) } which is what I've seen done in the Android Sunflower project as the proper way to submit LiveData to a RecyclerView. This works fine, and when I add items to my database they are updated in the RecyclerView. However, if I write viewModel.currentList.observe(viewLifecycleOwner){ adapter.submitList(it)...

Changing observed property value in EventHandler changes Event properties I have a TableView with a column of ComboBox cells, created with ComboBoxTableCell.forTableColumn(). I'm very new to JavaFX.

If it isn't confirmed, I want the cell's value to revert to what it was originally. The observed property is a SimpleStringProperty, and the table/row/bean type is a FooBar object.

Best way to load ~500 paragraphs plus options I'm just getting started and trying to make a simple app after going through some of the Google Codelabs. I wrote a Choose your own Adventure type of game. It consists of 500 paragraphs, and at the end of each paragraph is usually a choice of the next action to take (ie paragraph to load) and possibly some game logic. For now I am concentrating on the text only. It seems simpler to make 500 text files and load up whatever file number is necessary, however it makes more sense to load ALL the...

Why does the File I created from the Uri of a photo I picked not exist? [duplicate] My goal is to get the File Object of a photo, because the SDK API I am working with takes File as input. After I get the Uri of the photo I picked from my phone's gallery, I get the path out of the Uri, and then tried to create the File object out of it. I tested the Uri by creating a bitmap out of it and using the bitmap to update an imageView on my app, which works. So it approves that the Uri is correct. But why the Film object I created from it cannot pass the file.exists() check?...

When onActivityResult called, coroutine context is not yet created I am using Conductor (https://github.com/bluelinelabs/Conductor) for Android to replace Fragments. I was implementing image picking in my app and realized that onActivityResult is called before Controller's onAttach, in case of Fragments, equivalent would be onResume. It would be fine, but my problem is that I use coroutines and the coroutine context is created when my presenter is attached (which is a...
