Usage

From source file:Main.java

public static void assetsDataToSD(String fileOutPutName, String fileInPutName, Context context)
        throws IOException {
    InputStream myInput;/*ww w.  j ava2s .  c  o  m*/

    /*if (!file.exists()) {
    file.createNewFile();
       }else {
       return;
    }*/
    OutputStream myOutput = new FileOutputStream(fileOutPutName);
    myInput = context.getAssets().open(fileInPutName);
    byte[] buffer = new byte[1024];
    int length = myInput.read(buffer);
    while (length > 0) {
        myOutput.write(buffer, 0, length);
        length = myInput.read(buffer);
    }

    myOutput.flush();
