Android save created tempfile file to new folder
To save a created tempfile file to a new folder in Android, you can use the following steps:
-
Create a tempfile using the
java.io.TempFile
class:File tempFile = File.createTempFile("temp", ".txt");
This will create a tempfile with a random name in the system's temporary directory.
-
Move the tempfile to the new folder using the
File.renameTo()
method:File newFolder = new File("/path/to/new/folder"); tempFile.renameTo(new File(newFolder, tempFile.getName()));
This will move the tempfile to the new folder and rename it to the same name as the original tempfile.
Here's the complete code:
import java.io.File;
import java.io.TempFile;
public class TempFileExample {
public static void main(String[] args) {
// Create a tempfile
File tempFile = File.createTempFile("temp", ".txt");
// Move the tempfile to a new folder
File newFolder = new File("/path/to/new/folder");
tempFile.renameTo(new File(newFolder, tempFile.getName()));
// Verify the tempfile has been moved
File movedFile = new File(newFolder, tempFile.getName());
if (movedFile.exists()) {
System.out.println("Tempfile moved successfully!");
} else {
System.out.println("Error moving tempfile!");
}
}
}
Note that the File.renameTo()
method may throw a FileNotFoundException
if the file does not exist, or a SecurityException
if the file is not accessible. You should handle these exceptions accordingly.
Also, make sure to check the permissions of the new folder and the tempfile to ensure that the app has the necessary permissions to write to the folder and rename the file.
