如何在android中使用gzip压缩大字符串

Question

我尝试在android中压缩大字符串像这样：

try {
        String str = "MyLarge String";
          ByteArrayOutputStream rstBao = new ByteArrayOutputStream(str.length());
            GZIPOutputStream zos = new GZIPOutputStream(rstBao);
            zos.write(str.getBytes());
            IOUtils.closeQuietly(zos);

            byte[] bytes = rstBao.toByteArray();

            String compressedString = Base64.encodeToString(bytes, true);
            Log.i("Compressed", compressedString);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

但是此代码返回了内存错误 outofmemory返回＆＃34; Base64.encodeToString（bytes，true）;＆＃34;线
如果有人知道，请帮帮我 谢谢。

试试这个

public static String compressString(String str) throws IOException{
if (str == null || str.length() == 0) {
return str;
}

BufferedWriter writer = null;

try{
File file =  new File("your.gzip")
GZIPOutputStream zip = new GZIPOutputStream(new FileOutputStream(file));

writer = new BufferedWriter(new OutputStreamWriter(zip, "UTF-8"));

writer.append(str);
}
finally{           
if(writer != null){
 writer.close();
 }
}
}
