Creates a buffered character-output stream that uses a default-sized output buffer.

Usage

From source file:Main.java

public static void writeNewFile(String filePath, String fileContents) {
    File f = new File(filePath);
    if (f.exists()) {
        f.delete();/*w w  w  .j a va  2  s . c o m*/
    }

    try {
        // Create file 
        FileWriter fstream = new FileWriter(f);
        BufferedWriter out = new BufferedWriter(fstream);
        out.write(fileContents);
        //Close the output stream
        out.close();
    } catch (Exception e) {
        Log.d(TAG, "Failed to create " + filePath + " File contents: " + fileContents);
    }
}
