I'm doing a practice application in which I do a CRUD in android studio 3.0.1 and I'm running the application directly on my cell phone.
The application works without any inconvenience but when I want to remove the BD in SQlite from the application to analyze the fields from my pc I can not find the directory associated with my application
And checked the memory of the cell where all the applications are and I can not find the folder associated with it.
Could you tell me if it is stored in some hidden directory or something, because I can not find the folder associated with my application?
Note: I also have an external memory in my cell phone which has been reviewed folder by folder but nothing.

You are looking at external storage. Your app will not have a directory there, unless you create one in your code.
Could you tell me if it is stored in some hidden directory or something
Your APK is not stored anywhere that a user can see, except perhaps on a rooted device.
I also have an external memory in my cell phone which has been reviewed folder by folder but nothing
That is removable storage. Your app will not have a directory there, unless you create one in your code.

Please help with a fast question.
We have an Android Application, and we added the tracking to see how the internal storage is used. Then we received a list of files & folders from the user's devices.
In that list, there is a bunch of lib-X folders in the app's data folder. The folder consumed a huge amount of user storage. They are named "lib-1", "lib-2", "lib-main", "lib-0", and on some devices it's just "lib" only.
If there are multiple lib-x folders, usually the lib-0 will be the biggest one and consume most of the storage.
I tried to reproduce it by installing the application on the same device but could not see them inside the storage.
I strongly believe it contains native libraries, but not sure how they are created.
Would you have any idea why/how the folder is created?
Thanks.
On my Samsung devices I put a file in the /Download folder. When I select the file within my app (via a file browser), the file is called /storage/emulated/0/Download/myfile.db. This name is stored in my app settings.
At the start of the app the file should be opened. First the app checks if the file exists. In some cases, say once every 2 weeks, the file is said to be not existing! This happens also at my friends mobile since half a year.
Why is that happening? For years everything ran smoothly.
This code runs for 6 years. Of course I added the permissions stuff.
Your help is much appreciated!
You can't use the Download as an guaranteed storage place for your files. You should use the Internal storage for the app. This is what Google has written about the download folder:
This space is called external because it's not guaranteed to be accessible—it is a storage space that users can mount to a computer as an external storage device, and it might even be physically removable.
Here you can read more about the Internal storage and the External storage in Android.
Here is some more information about the Download folder from Google.
Caution: The external storage might become unavailable if the user removes the SD card or connects the device to a computer. And the files are still visible to the user and other apps that have the READ_EXTERNAL_STORAGE permission. So if your app's functionality depends on these files or you need to completely restrict access, you should instead write your files to the internal storage.
I want to store music files downloaded from server in my application installation directory. I noticed that several android phones has different path to application installationo directory.
Such as Android/data, data/data and etc.
I develop the application with phoengap. I checked their api but coudnt get a methode that return application installaitn folder path.
Can anybody help me on this?
thanks
Due to security reasons, you cannot write to application install or the assets directory, instead you can write files in application data folder.

I just want to view the files(especially the .png files) associated with one of the application in my mobile. The application is actually installed(moved) in the SD card.
The issue is ..I could not find the application in the SD card. I am using a file browser called 'File Manager' to browse through the SD card. Can someone help me on this.
It should be here:
/mnt/sdcard/Android/data/your_package_name/
Some hardware implements the path to the external storage different.
/mnt/sdcard/Android/data/your_package_name/
/mnt/sdcard-ext/Android/data/your_package_name/
You may be able to get a better view of what is on the device by using the ADB Shell. If you still have trouble at this point trying running grep or find from the shell.
UPDATE
Most of the time the files associates with your application are in the directory with your application. The application is installed in /data/data/your.package.name/. However you will need root access to get here if you are on a phone, I think the emulator lets you get here. As far as external storage... yea its a pain, to much fragmentation in the market. You have to programmatically check the location of the external storage.
On my device with Android 2.3.6 apps moved on the SD card are located into a directory named .android_secure as .asec files (see http://www.fileinfo.com/extension/asec).
They are not visible from the standard "Archive" browser which shows the hidden directory as empty.
The files are also encrypted so I guess no access to the images within is possible.
I am trying to built an application that will alllow user to paste a text file in the Tablet Internal memory by browsing it trough connecting with PC ( IN SPECIFIC DIRECTORY ) and do some file-operations to it through application. After that user will be able to browse the directory again and copy the final-file .
IS there a way to do that?
I can store the final-file in application 'SANDBOX" through application but the user will not be able browse the sandbox. So what is the possible solutions
THANKS
Files created in an application's private storage (what you are calling the "sandbox") area can be given mode world readable so that other tools can access them, however relatively few other applications would know how to find them.
Files that you desire to make generally available should be placed instead on the "external storage" which confusingly on a lot of devices (especially tablets) is built in, rather than a removable memory card. At this point what really distinguishes "external storage" is that data there is naturally shared between apps and easily browsed by the user with common file manager apps (android doesn't tend to come with a file manager, but there are lots out there you can add)
