Android开发(42) 获取android手机基本信息

一  权限配置:

<!-- 获取mac地址权限 -->  
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />    
<!--获取手机信息权限 -->  
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />

二  java代码：

	/**
	 * 获取android当前可用内存大小
	 */
	private String getAvailMemory() {// 获取android当前可用内存大小

		ActivityManager am = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
		MemoryInfo mi = new MemoryInfo();
		am.getMemoryInfo(mi);
		// mi.availMem; 当前系统的可用内存

		return Formatter.formatFileSize(getBaseContext(), mi.availMem);// 将获取的内存大小规格化
	}

	/**
	 * 获得系统总内存
	 */
	private String getTotalMemory() {
		String str1 = "/proc/meminfo";// 系统内存信息文件
		String str2;
		String[] arrayOfString;
		long initial_memory = 0;

		try {
			FileReader localFileReader = new FileReader(str1);
			BufferedReader localBufferedReader = new BufferedReader(
					localFileReader, 8192);
			str2 = localBufferedReader.readLine();// 读取meminfo第一行，系统总内存大小

			arrayOfString = str2.split("\\s+");
			for (String num : arrayOfString) {
				Log.i(str2, num + "\t");
			}

			initial_memory = Integer.valueOf(arrayOfString[1]).intValue() * 1024;// 获得系统总内存，单位是KB，乘以1024转换为Byte
			localBufferedReader.close();

		} catch (IOException e) {

<span style="white-space:pre">		</span>    e.printStackTrace();
		}
		return Formatter.formatFileSize(getBaseContext(), initial_memory);// Byte转换为KB或者MB，内存大小规格化
	}

	 * 获得手机屏幕宽高
	 * 
	 * @return
	 */

		String mtyb = android.os.Build.BRAND;// 手机品牌
		String numer = mTm.getLine1Number(); // 手机号码，有的可得，有的不可得
		Log.i("text", "手机IMEI号：" + imei + "手机IESI号：" + imsi + "手机型号：" + mtype+ "手机品牌：" + mtyb + "手机号码" + numer);

	 */
	private String[] getCpuInfo() {
		String str1 = "/proc/cpuinfo";
		String str2 = "";

		String[] arrayOfString;
		try {
