android 下Protobuff常用的框架有三个: protobuff自身, square出的wire , protostuff
由于protobuff会为每个属性生成大量不常用的方法,当程序比较复杂时容易超过android的60K个方法的上限, 所以本次测试未包括protobuff
测试逻辑是循环100次序列化100个元素的数组,并反序列化,求平均值,代码如下:
wire的测试代码:
public void onClickButton(View view){ if (TestTask.isCancel){ TestTask.isCancel = false; TestTask.sumDeserializeTime = 0; TestTask.sumTime = 0; TestTask.runCount = 0; TextView text1 = (TextView) findViewById(R.id.textView2); text1.setText(""); new TestTask( (TextView) findViewById(R.id.textView2) , (TextView) findViewById(R.id.button1)).execute(); ((TextView)view).setText("测试中,点击中断"); }else{ ((TextView)view).setText("正在中断..."); TestTask.isCancel = true; } } static class TestTask extends AsyncTask<Void,Void,Long>{ long serializeTime=0; long deserializeTime=0; static long sumTime=0; static long sumDeserializeTime=0; static int runCount=0; static boolean isCancel=true; TextView text1; TextView btn; public TestTask(TextView text1,TextView btn) { this.text1 = text1; this.btn = btn; } @Override protected Long doInBackground(Void... params) { long startTime = System.currentTimeMillis(); for (int i = 0; i < 100; i++) { List<ListItem> itemList = new ArrayList<ListItem>(); ListItem.Builder itemBuilder = new ListItem.Builder(); ListItem item; for (int j = 0; j < 100; j++) { item = itemBuilder.title("test Title"+i+":"+j) .remark("test Remark"+i+":"+j) .coverUrl("http://pic.ozreader.com/abc.pic") .uri("PKB:TESTURI") .build(); itemList.add(item); } ScrollList.Builder listBuilder= new ScrollList.Builder(); ScrollList list = listBuilder.haveMore(false).tags(itemList).build(); byte[] dataBuffer = list.toByteArray(); serializeTime = System.currentTimeMillis()-startTime; Wire wire = new Wire(); try { ScrollList resultList = wire.parseFrom(dataBuffer, ScrollList.class); if (resultList == null){ Log.e("TEST", "resultList is null"); break; }else if (resultList.tags == null){ Log.e("TEST", "resultList.tags is null"); break; }else if (resultList.tags.size() <= 0){ Log.e("TEST", "resultList.tags is empty"); break; }else if (resultList.tags.size() != 100){ Log.e("TEST", "resultList.tags is wrong"); break; }else if (!resultList.tags.get(0).uri.equals("PKB:TESTURI")){ Log.e("TEST", "resultList.tags content is wrong"); break; } deserializeTime = System.currentTimeMillis()-startTime-serializeTime; } catch (IOException e) { e.printStackTrace(); } } return System.currentTimeMillis() - startTime; } @Override protected void onPostExecute(Long result) { sumTime += result; sumDeserializeTime += deserializeTime; runCount ++; text1.append("result:"+result+", serializeTime:"+serializeTime+", deserializeTime:"+deserializeTime+", runCount:"+runCount+", avg:"+sumTime/runCount+", avg deserializeTime:"+sumDeserializeTime/runCount+"\n"); if (isCancel){ text1.append("测试中断."); btn.setText("开始测试"); }else if (runCount < 100){ new TestTask(text1,btn).execute(); }else{ isCancel = true; text1.append("测试完成."); btn.setText("开始测试"); } } } |
