通过adb采集app性能的native heap、dalvik heap、psstotal大小

之前在百度看了好几多资料，耐烦出现好多坑，估计是时间太久了，导致不适用，现在我贴上我的代码，大家看一下，本人已通过编译，可以正常运行

	public static String[] getHeap(String packageName) {
		String cmd = "adb shell dumpsys meminfo " + packageName;
		String PSS = null;
		String Native = null;
		String Dalvik = null;
		Process p = null;
		try {
			p = Runtime.getRuntime().exec(cmd);
			InputStream in = p.getInputStream();
			BufferedReader bReader = new BufferedReader(new InputStreamReader(in));
			StringBuffer sb = new StringBuffer();
			String line = "";
			while ((line = bReader.readLine()) != null) {
				sb.append(line + " ");
				String data = sb.toString();
				// System.out.println(data);
				PSS = getPSS(data);
				if (PSS == null) {
					continue;
				}
				Native = getNative(data);
				if (Native == null) {
					continue;
				}
				Dalvik
