android内存泄漏测试

要测内存泄漏呢，可以反复进入某一项操作，如反复进入联系人详情后返回键，观察内存的值是否有上升的趋势。

测试方法：

1.创建自动化测试脚本，每操作一次获取一次内存值，然后把内存值导出到文件中，制作成曲线图，就可以很直观的看见是否存在内存泄漏了。曾经用Uiautomator做过一次内存泄漏的脚本，如下：

package demotest;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.text.SimpleDateFormat;
import java.util.Arrays;
import java.util.Date;

import com.android.uiautomator.core.UiObject;
import com.android.uiautomator.core.UiObjectNotFoundException;
import com.android.uiautomator.core.UiScrollable;
import com.android.uiautomator.core.UiSelector;
import com.android.uiautomator.testrunner.UiAutomatorTestCase;

public class MemoryLeak extends UiAutomatorTestCase {
    // 应用包名
    static final String packageName = "com.android.phone";

    // 测试次数
    static final int counts = 500;
    public static void main(String[] args) {
        String jarName, testClass, testName, androidId;
        jarName = "demotest";
        testClass = "demotest.MemoryLeak";
        testName = "testScene_03";
        androidId = "3";
        new UiAutomatorHelper(jarName, testClass, testName, androidId);

    }

     // 场景一：打开/退出联系人

    public void testScene_01() throws IOException {
        File mTxt = mkFile("01");// 创建文件
        FileOutputStream fos = null;// 以字节流的形式读取
        fos = new FileOutputStream(mTxt);
        for (int i = 0; i < counts; i++) {
            scene_01();// 执行场景一的case
            sleep(2000);// 延迟2s
            String mMemory = memory(packageName);// 读取每一次的memory
            sleep(2000);
            byte[] b1 = (mMemory + "\n").getBytes();
            fos.write(b1);
        }
        fos.close();
    }

    //场景二：查看联系人
    public void testScene_02() throws IOException
    {
        File mTxt = mkFile("02");// 创建文件
        FileOutputStream fos = null;// 以字节流的形式读取
        fos = new FileOutputStream(mTxt);
        scene_01();//打开联系人
        for(int i=0;i<counts;i++)
        {
            getUiDevice().click(334, 416);
            sleep(1000);
            getUiDevice().pressBack();
            String mMemory = memory(packageName);// 读取每一次的memory
            sleep(2000);
            byte[] b1 = (mMemory + "\n").getBytes();
            fos.write(b1);
        }

        fos.close();

        String line, Pss = null;
        try {

    // 创建文件保存日志
    public File mkFile(String casename) {

        File filePath = new File(path);
        File txt = new File(file);
        if (!filePath.exists() && !txt.exists()) {
            filePath.mkdirs();
            try {

            } catch (IOException e) {

            }
        }
        return txt;
    }

}

2.用 bat脚本连续读取应用程序的内存使用情况（一边操作一边观察内存值是否一直上升）

set process=com.android.contacts
@adb shell dumpsys meminfo %process% | findstr "Pss"
:m
@adb shell dumpsys meminfo %process% | findstr "TOTAL"
@ping -n 5 127.1>nul
@goto m

3.用eclipse中的DDMS

手动连电脑，选中要测试的进程名--点击Update help--操作应用的同时观察右边Heap区域的total size是否会一直上升，在此期间可以点击GC按扭触发android垃圾回收

如果一直呈上升趋势则点击Dump HPROF按扭把内存映像拷贝下来，然后用MAT工具去分析。
