Copying raw file into SDCard?
Read from the resource, write to a file on the SD card:
InputStream in = getResources().openRawResource(R.raw.myresource);
FileOutputStream out = new FileOutputStream(somePathOnSdCard);
byte[] buff = new byte[1024];
int read = 0;
try {
while ((read = in.read(buff)) > 0) {
out.write(buff, 0, read);
}
} finally {
in.close();
out.close();
}
Copy file from raw to External Storage:
This is a method that i use to do this job, this method receive the resource id, and the name desired for storage, for example:
copyFiletoExternalStorage(R.raw.mysound, "jorgesys_sound.mp3");
method:
private void copyFiletoExternalStorage(int resourceId, String resourceName){
String pathSDCard = Environment.getExternalStorageDirectory() + "/Android/data/" + resourceName;
try{
InputStream in = getResources().openRawResource(resourceId);
FileOutputStream out = null;
out = new FileOutputStream(pathSDCard);
byte[] buff = new byte[1024];
int read = 0;
try {
while ((read = in.read(buff)) > 0) {
out.write(buff, 0, read);
}
} finally {
in.close();
out.close();
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
Environment.getExternalStorageDirectory() this method is deprecated in API level 29 and it will not allow to create a directory/file on given path.
Below code is working for creating directory and downloading file from /res/raw directory.
If your device have Android 10 (API Level 29) or greater it will download your file on below location
File manager--> Storage --> Android --> data --> com.yourapp.packagename --> files --> FOLDER_NAME --> file_name.png
private void downloadFileFromRawFolder(){
try {
InputStream in = getResources().openRawResource(
getResources().getIdentifier("file_name",
"raw", getPackageName())); // use only file name here, don't use extension
File fileWithinMyDir = new File(checkFolder(), "file_name.png"); //Getting a file within the dir.
Log.e("FILEPATH ", "fileWithinMyDir " + fileWithinMyDir);
FileOutputStream out = new FileOutputStream(fileWithinMyDir);
byte[] buff = new byte[1024 * 1024 * 2]; //2MB file
int read = 0;
try {
while ((read = in.read(buff)) > 0) {
out.write(buff, 0, read);
}
} finally {
in.close();
out.close();
}
Log.d(TAG, "Download Done ");
} catch (IOException e) {
Log.e(TAG, "Download Failed " + e.getMessage());
e.printStackTrace();
}
}
