Reads some number of bytes from the input stream and stores them into the buffer array b.

Usage

From source file:Main.java

public static byte[] suckFile(String inputfile) throws IOException {
    InputStream is = context.openFileInput(inputfile);
    int size = is.available();
    byte[] content = new byte[size];

    is.read(content);

    is.close();//  w  w  w  . ja v a  2  s .c om
    return content;
}

From source file:Main.java

static void copyData(InputStream from, OutputStream to) throws IOException {
    byte[] buffer = new byte[1024];
    int length;// w  w w.  ja v a  2  s . co  m
    while ((length = from.read(buffer)) > 0) {
        to.write(buffer, 0, length);
    }
    to.flush();
    to.close();
    from.close();
}

From source file:Main.java
