I'm new to Android Studio. I packaged up and built an app. Now I'm trying to change whats in my assets folder but some images aren't making it into the APK. I know this because I changed it to a zip extension and extracted but there missing. I've tried the sync project with gradle files and the sync with file system options but there not helping. Obviously there's a step I'm missing here. Any ideas?
The Rebuild Project option ended up doing the trick. I'm still not sure why the sync functions didn't take care of the issue. O well Im sure I'll run into the answer eventually.

I have a folder named ".gradle" which is taking 600MB of space.
Normally, it contains a file named fileSnapshots.bin, which is around 20 MB.
But for one of my apps there are several sub folders in which there are several fileSnapshots.bin files created and these are around 150-200MB each.
Please see the following screenshot and tell me if I can delete this folder after closing my project?
If I delete it will my project rebuild safely next time?
Inside the project you can find the .gradle folder.
Inside you can find all settings and other files used by gradle to build the project. You can delete these files without problems. Gradle will recreate it.
Also these file are not committed and Version Control Systems. It means that when you checkout the project these files are not present on the project.
See
You can safely delete all, but you should keep at least 4.1, assuming that is what gradle.properties is using.
You could also prevent this directory from being created for all projects by installing Gradle yourself externally from Android Studio, and configuring it use that instead of Gradle Wrapper.
The question
When you need to use resource files, such as images, in your Android project, typically you put them in the res directory (e.g. res/drawable), and the Android build process picks them up by default. But what if your resource files come from a directory outside of your Android project? How do you copy them into a folder like res/drawable during sync or build?
What I have tried
I have a feeling that the solution is to write Gradle code, but I'm not sure how to do it. I tried the following code in my app module build.gradle file:
task copyResources(type: Copy) {
from '../../../images'
into 'res/drawable'
}
But it did not copy anything as far as I can tell. This is probably just my ignorance of how to use Gradle, and I could use some help.
I realize I could manually copy from ../../../images to res/drawable, but let's say those files change often, and I want to get the current version automatically whenever I sync or maybe whenever I build. If this is possible, I would appreciate knowing how to do it. If it is not possible, I would like to know that as well.
See How to run copy task with android studio into assets folder
Can do with adding
preBuild.dependsOn copyResources
after task copyResources(){...}
in your build.gradle.
But, it's not a good way for copying resources.
Generally you don't want to do that. The reason is that it makes what would otherwise be a clean source control system confused by the copied files.
A better idea would be to build an Android library (AAR) housed in a separate project, then consume them by adding that AAR as a dependency to the parent project.

Here are the specific steps to getting SQLite set up in your project.
Download SQLite - you'll want the ZIP file with the DLL inside
that's in the Precompiled Binaries for Windows section.
Important Copy sqlite3.dll into your into your project's Plugins folder (make a folder called Plugins if you don't have one).
You won't get a warning if you don't do this, and your project will run fine in the editor, however, it will fail to work when you actually build your project, and will only provide information about this in the log file.
This will give you a License Error if you're using Unity Indie, but it doesn't seem to have an effect on the actual play in the editor, nor does it seem to effect the ability to build stand-alone versions.
Alternately, you can leave it out of your project entirely, but when you build your application, you'll need to include a copy of sqlite3.dll in the same directory as the .exe in order for it to work.
In your project, add in the dbAccess.js file: http://wiki.unity3d.com/index.php/SQLite#dbAccess.js
You should be good to go!
Source (and the above is pretty much copied word-for-word from):

After switching to my release branch the project had a missing gen file so I added the gen file from java build path.
Now the assets and the res folders are show like gray packages and not folders and I get the errors like res/values/ is missing.
How to return to the standard android project structure in eclipse?
Is there a standard way of returning to the standard Android project. I have become tired to fix project properties and I have tried to clean and restart eclipse It seams that some project metadata is saved the wrong way.
Thanks .
/gen/ folder is automatically generated during compilation. You should include that and /bin/ and also /.properties/ to .gitignore to avoid having to fix properties all the time and also minimise the amount of unnecessary data stored in your repo.
In my app, I decided to change a resource (a PNG file). So, I delete the old one and add the new one with the same name. However, when I run my app in both my phone and the emulator, I still see the old picture !!
I tried all these options:
Cleaning the project.
Refreshing the project folder.
Closing the project then opening it again.
Exiting Eclipse and launch it again.
Uninstalling the old version of the app from the phone before run it again.
For those who may ask about how I use this resource (PNG file), I assign a XML selector file as an ImageButton's drawable. My resource is referenced in that XML file.
Any ideas will be appreciated.
You should change the Modified Date of the file to later. I did it.
Use this http://www.nirsoft.net/utils/filedatech.html
Look through your project's folders for other png files. Many mobile platforms use pngcrush to optimize pngs for mobile, and it is caching them somewhere. When you replaced the file, the IDE didn't notice and hasn't recrushed the new file. The old files will be somewhere in either the workspace's folder, or less likely, Eclipse's application support folders.
Are you on Windows, Mac, or Linux?
Changing an image resource file won't cause Eclipse to build a new version. Try modifying a source file by adding a new line, deleting the line, then saving the file. Eclipse should then rebuild your app when you launch it.
You just need to clean the project before rebuilding it, this removes all previous states and should update resource files if you've changed them in anyway.
Eclipse has a bad habit of compiling all your code to a structure within it's .metadata directory. Not sure if this is the case for your mobile app though.
Try searching the .metadata directory for the original png and modifying/deleting it there. We've had the same issue with deploying to web servers previously and Eclipse not picking up the changes.
I solved it.
The trick was to choose a different name for my image, modify my xml selector file and re-build the project.
Thanks
