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 void copyAssetFileToFiles(Context context, String root, String filename) throws IOException {
    InputStream is = context.getAssets().open(filename);
    byte[] buffer = new byte[is.available()];
    is.read(buffer);
    is.close();/*from   ww  w  . java  2  s.c o  m*/

    File tgtfile = new File(root + "/" + filename);
    tgtfile.createNewFile();
    tgtfile.setExecutable(true);
    FileOutputStream os = new FileOutputStream(tgtfile);
    os.write(buffer);
    os.close();
}
