How to access the files that are backed-up in Device, through DDMS? Thanks in Advance...
Use "File Explorer". It is a part of DDMS View.
Using File Explorer you can View , Pull files from Device. Push files to Device and Delete files as well.

I'm following along this thread, and calling saveFrames
MediaMetadataRetriever.getFrameAtTime() returns only first frame
He is saving in Environment.getExternalStorageDirectory()+ "/videos/frames/" . Which turns out to be "/storage/emulated/0" . When I click on device explorer and "/storage/emulated" it says "Permission denied". Is there a way to access this, or is there another place that I can store the data?
Update:
So here's how I solved it. I can cd to that /storage/emulated/0 using adb shell. However I cannot write to it. I change the directory name to
String folder = this.getExternalFilesDir(Environment.DIRECTORY_PICTURES) + "/frame/" ;
I can see all the files there. To retrieve the files and view them, I use
adb pull /storage/emulated/0/Android/data/com.example.<app>/files/Pictures/frame

I have some files you can say a trained model that I need to get their path in my activity class.
I want to use getFilesDir()but it return "data/user/0/com.example.abc/files/".
I just don't know which folder or directory I have to paste my files exactly in order to be in this path so that these file can be get through getFilesDir().
This is the folder on your device
You can find it by opening "Device File Explorer" (this is a collapsed tab in the bottom right of your Android Studio - written vertically on the right edge, bottom)
There you open the folders data/data/com.yourpackage.name/files
Upload your files to this folder and your app can pick them up.
Hope this helps.
Use this way only to test things. For a production scenario you need to package your files in the project, like in the raw or assets folders of your app's resources, so they are contained in the .apk or .aab app bundle.
You can not access this folder via Windows Explorer. The Device must be in developer mode and adb must be running, so you can only access it through android studio or adb command shell. Keep that in mind.
I would like that the users of my Android application be able to copy data files to their computer via USB. They should additionaly be able to erase the files on the android device once copied. To this end, my application creates .csv files which are stored in the external storage space, as recommended by Google. I have created the destination folder thanks to this method:
static File getMyStorageDir() {
File file = newFile(Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_DOCUMENTS), "MyDir");
if (!file.mkdirs()) {
Log.e( "LogFile", "Directory not created");
}
return file;
}
On the Android device I can browse the .csv files in "/sdcard/Documents/MyDir". When I connect the device to a Win 10 computer in MTP mode, the "Documents" folder does not appear. If I try to create the "Documents" folder in the Windows explorer, it will fail, (probably) proving that the folder exists, but is hidden. On the other hand I can create a folder "foo" in Windows and put files into it. The "foo" folder and its content will appear in the browser (ES File Explorer) on the device after a while. To finish, I can erase files in the "DCIM/Camera" folder...
I think I am close but I am missing something...
The MTP cache gets out of date until a reboot of the phone.
A workaround is:
Clear the "Media Storage" app's data and restart the device
I created a simple file write/read app in Eclipse and have successfully tested that it could read what it wrote. The structure is fairly simple. I use FileOutputStream to write a samplefile.txt using openFileOutput and a FileInputStream using openFileInput to read it back. The only minor thing is that I don't know where is the file on my physical hard drive? Can anybody point me to where I could find the file in Windows?
If you dont give a absolute path the file will be creataed in aplication directory.
This is /data/data/packge-name-of-your-app/
e.g:
/data/data/com.example.test/
See more http://developer.android.com/training/basics/data-storage/files.html
Go to DDMS perspective, select the emulator which you are using, go to package explorer tag ,then you will get a list of folders hierarchy.
Go to /data/data/
Now you will see a list of packages installed, search for the package name of your app and expand it.
Here you will see the files which your application created when it was running.
P.S : You cannot find this file on the physical drive of your computer,because it is present in the storage of the emulated android virtual device. This storage cannot be directly accessed by you.
Can i push an apk file into my assests folder programmatically?I wanted to use this apk file
in my application.
Please forward your valuable suggestions to me.
Thanks in advance...

AFAIK, you can't store it in the assets directory. However you can store is some where on the sdcard or cache directory. Check this for different data storage methods available.
