I have successfully stored bitmap in sdcard/Pictures folder in android 2.X , using following code
File path = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
File file = new File(path, "pic"+index+".jpg");
now, i want to retrieve all the images stored in that folder with out specifying name of the file.
You can get a list of all the files in a directory with
http://developer.android.com/reference/java/io/File.html#listFiles()
You probably want to add a filefilter so that you only return jpg files you are interested in
File filters you can read about here

How to upload the entire folder of images (in the particular directory) onto Dropbox using Dropbox API?
In the sample code, it uploads the particular file which is of the same filename, however, I saved the image filenames according to the time at which it is taken and therefore, I was not able to upload any file saved.
I tried to use:
File path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
String imageFileName = "Pictures" + date.toString()+ ".jpg";
File file = new File(path+File.separator, imageFileName);
But no file was found when I tried uploading.
I'm trying to develop a simple android app. I want to know if an image exist in one of my apps' folder, but I don't know what's the root of my app. I tried...
File nomeFile = new File("res/drawable-hdpi/imagename.jpg")
File nomeFile = new File("myappanem/res/drawable-hdpi/imagename.jpg")
...but it doesn't work.
Try This :
File YourFile = new File(Environment.getExternalStorageDirectory(), "/Android/data/....yourfile.txt");
No you cant access drawable or manifest after packaging. because there will be no "drawable" folder or manifest file at all. All your drawables packed in APK file after installation. You cant reach them.
But you can access any folder of your phone in your app like that.
Firstly make directory.
File directory = new File(Environment.getExternalStorageDirectory()+File.separator
+"Your folder");
directory.mkdirs();
Access your folder like that.
String fileUrl = "/Your folder/a.png";
String file = android.os.Environment.getExternalStorageDirectory().getPath() +
fileUrl;
File f = new File(file);
whether your taking about internal memory of your application cache directory
//use this for internal memory
String path =Environment.getDataDirectory().getAbsolutePath();
File myImage=new File(path,"your file name.extension");
//use this for cache directory
String path=getApplicationContext().getDir("" , Context.MODE_PRIVATE);
File myImage=new File(path,"your file name.extension")
I need the route of a pdf file in my Android Project.
The file could be in raw or in assets folder.
I need to get the route because I must call using the File Class
Ex: File file = new File(path);
Thanks

I am not quite sure what you mean, assuming you want to read to PDF file in your assets (res file) look here
Access PDF files from 'res/raw' or assets folder programmatically to parse with given methods
But if you want to get the file path of a folder, then look here
how to get file path from sd card in android
How to get the file path from URI?
Here is an example of how to get a file path (taken from the third link)
File myFile = new File(uri.toString());
myFile.getAbsolutePath()
The file i want to open is located in the file:
/data/data/MY_PACKAGE/files/samplefile.txt
I have pulled the file from ddms and the desired content is in it
I just want to get the text file in order to parse it..
I tried the following:
File sdcard = Environment.getExternalStorageDirectory();
//Get the text file
File xmlFile = new File(sdcard,"samplefile.txt");
but no joy...
Thanks in advance!!
Use getFilesDir(), not Environment.getExternalStorageDirectory(), to get at the root of internal storage, where your file resides.
In order to open a file stored within your applications private directory you must use openFileInput(String fileName). This will return a FileInputStream that you can then work with.
A few WAV files used by my app are currently located in res/raw. These files need to be accessible by the user after the app is installed. So ideally my app should create a folder on the device and put the files in it. Any idea/suggestions on how to do this?
soundIds[0] = soundPool.load(test2Activity, R.raw.snare, 1);
soundIds[1] = soundPool.load(test2Activity, R.raw.snare2, 1);
You can access the sd_card, so you can create a directory and put there your files
// create a File object for the parent directory
File yourDirectory = new File("/sdcard/YourDirectory/");
// have the object build the directory structure, if needed.
yourDirectory.mkdirs();
// create a File object for the output file
File outputFile = new File(yourDirectory, filename);
// now attach the OutputStream to the file object, instead of a String representation
FileOutputStream fos = new FileOutputStream(outputFile);
The output file should be your sound that you have loaded from res/raw.
My advice would be to just copy the sound to the folder, and still use the sound from res/raw from within your app because
1) it is easier since you can access it as a resources
2) you are sure the user didn't deleted the directory.
Remember to put the user permission "android.permission.WRITE_EXTERNAL_STORAGE" in the manifest
