How to write in pipes for Android

UnixPipeActivity.java

package fr.stackr.android.upt;

import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStreamWriter;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;

public class UnixPipeActivity extends Activity {

	public final static String PATH = "/data/data/fr.stackr.android.upt/pipe/v_pipe";

	public final static String TAG = "UPIPE";

	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		
		Log.i(TAG, "Attempt started");
		OutputStreamWriter out;
		try {
			out = new OutputStreamWriter(new FileOutputStream(PATH));
			Log.v(TAG, "SEND :: Try to write the first paragraph ....");
			out.write("Try to write the first paragraph ....");
			Log.v(TAG, "SEND :: Bip\n");
			out.write("Bip\n");
			Log.v(TAG, "Flushing...");
			out.flush();
			Log.v(TAG, "SEND :: Bip post flush");
			out.write("Bip post flush");
			Log.v(TAG, "Closing…");
			out.close();
		}  catch (FileNotFoundException e) {
			Log.e(TAG, "Error: the pipe opening failed.");
			e.printStackTrace();
		} catch (IOException e) {
			Log.e(TAG, "Error: during writing");
			e.printStackTrace();
		}finally {
			Log.i(TAG, "Attempt ended");
		}
	}
}

Sorry, I forget the mkfifo function in C, now it is a named pipe and works fine.

@F-Sidney, can you also create the named pipe in Java?

@corwin-of-amber No.
