Android SQLite Query, Insert, Update, Delete, Always Need to be On Background Thread?

由 强颜欢笑 提交于 2019-12-04 23:32:15
I currently use Loaders to grab data from my ContentProvider (to enable auto-updating of my Cursors). This approach is straight-forward for Querying the database, though, it seems ill suited for any other DB operation (such as Insert, Update, Delete). My questions are: Do all SQLite operations need to be on a background thread, or is it safe to do simple operations like Inserting, Updating, or Deleting a single row on the UI thread? What is a nice design patter to ensure all queries go through a background thread? I would like to implement AsyncTask, should I create a SuperTask so to speak

change jspm_packages location

由 我怕爱的太早我们不能终老 提交于 2019-12-04 19:35:09
问题 Is there a .bowerrc equivalent in jspm ? When I run jspm install , I'd like jspm to install the packages to client/jspm_packages folder. How can I configure jspm to change location of jspm_packages folder? Thanks 回答1: I found it. In your package.json , add the path into packages inside directories . "jspm": { "directories": { "packages": "new/path/to/jspm_packages" } } 来源： https://stackoverflow.com/questions/29902646/change-jspm-packages-location

Using pagination with CursorLoader and MergeCursor closes old cursors

由 早过忘川 提交于 2019-12-04 18:08:49
As the title says, when trying to paginate a ListView backed by a SimpleCursorAdapter and a CursorLoader , old cursors are getting closed, thus the below exception is being thrown. The first 2 pages load just fine (the first isn't using the MergeCursor and the second page is the first one to use the MergeCursor ). I don't call any close() on any cursor whatsoever. What is interesting is that while debugging, I cannot see the closed flags on any cursor being set as true, for what it's worth. Might be an issue with the MergeCursor then. Let me know if you guys have any solutions, I'm out of

Windows initial execution context

由 安稳与你 提交于 2019-12-04 14:44:53
Once Windows has loaded an executable in memory and transfert execution to the entry point, do values in registers and stack are meaningful? If so, where can I find more informations about it? Officially, the registers at the entry point of PE file do not have defined values. You're supposed to use APIs, such as GetCommandLine to retrieve the information you need. However, since the kernel function that eventually transfers control to the entry point did not change much from the old days, some PE packers and malware started to rely on its peculiarities. The two more or less reliable registers

What is the point of the Global Offset Table?

由 会有一股神秘感。 提交于 2019-12-04 12:04:41
The whole reason the GOT works is that the offset between the code and data sections is constant; ergo, the offset between the code and some given datum in the data section is constant. This SO question addresses this, and confirms that for data defined in the library, the GOT is redundant. The only possibility left is data used in the library, but defined elsewhere. Thus, is the only point of the GOT in a shared lib, to be able to keep that lib's code section position-independent by localizing all relocations to symbols defined in other shared libraries , in the GOT? Thus, is the only point

LoaderManager does not accept 'this'

Okay, I surrender. I cannot figure it out. I'm following a Udacity course on Android Basics and need to figure out how to load data using a Loader. However, when I use the following line, the 'this' is highlighted in red and showing the following error: Wrong 3rd argument type. Found 'com.example.carl.latestnews.MainActivity', required: 'android.app.LoaderManager.LoaderCallbacks<java.lang.Object> I've googled, stacked and tried suggestion I've found. I've tried creating an inner class which implements the call backs. I've hit a brickwall and I'm sat here scratching my head trying to figure out

Webpack 3 locates .mp4 file but video is not playable

问题 Webpack 3 locates .mp4 file but video is not playable Clone this project on GitHub I've created an animation in Adobe's new Animate CC and exported it as an .mp4 file In my webpack.config.js file, I stated that the file-loader should be used to load my .mp4 file like so: webpack.config.js { test: /\.(mov|mp4)$/, use: [ 'file-loader' ] } (You can find my webpack.config.js source code below) So why, when I run webpack (or rather locally, webpack as an npm script) package.json "build:dev":
