android 获得一些设备信息的静态函数

1.Brand,IMEI,DeviceOS,DeviceFactoryTime

	public static String getDeviceBrand(Context context) {

		String brand = "";

		brand = android.os.Build.BRAND;

		Editor editor = SharePreferencesUtils.getAppInfoSharedPreferenceEditor(context);

		editor.putString(Constants.KEY_SHAREPERFERENCES_BRAND, brand);

		editor.commit();

		return brand;

	}



	public static String getDeviceImei(Context context) {

		String imei = "";

		imei = ((TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE)).getDeviceId();

		Editor editor = SharePreferencesUtils.getAppInfoSharedPreferenceEditor(context);

		editor.putString(Constants.KEY_SHAREPERFERENCES_IMEI, imei);

		editor.commit();

		return imei;

	}



	public static String getDeviceOS(Context context) {

		String OS = gOSName + " " + android.os.Build.VERSION.RELEASE;

		Editor editor = SharePreferencesUtils.getAppInfoSharedPreferenceEditor(context);

		editor.putString(Constants.KEY_SHAREPERFERENCES_OS, OS);

		editor.commit();

		return OS;

	}



	public static String getDeviceFactoryTime(Context context) {

		String factoryTime = Long.toString(android.os.Build.TIME);



		Editor editor = SharePreferencesUtils.getAppInfoSharedPreferenceEditor(context);

		editor.putString(Constants.KEY_SHAREPERFERENCES_FACTORY_TIME, factoryTime);

		editor.commit();

		return factoryTime;

	}

 2.可用内存，已用内存，剩余内存

	public static String getAvailableInternalMemorySize(Context context) {

		File path = Environment.getDataDirectory();

		StatFs stat = new StatFs(path.getPath());

		long blockSize = stat.getBlockSize();

		long availableBlocks = stat.getAvailableBlocks();

		return Formatter.formatFileSize(context, availableBlocks * blockSize);

	}



	public static String getTotalInternalMemorySize(Context context) {

		File path = Environment.getDataDirectory();

		StatFs stat = new StatFs(path.getPath());

		long blockSize = stat.getBlockSize();

		long totalBlocks = stat.getBlockCount();

		return Formatter.formatFileSize(context, totalBlocks * blockSize);

	}



	public static boolean externalMemoryAvailable() {

		return Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED);

	}



	public static String getAvailableExternalMemorySize(Context context) {

		if (externalMemoryAvailable()) {

			File path = Environment.getExternalStorageDirectory();

			StatFs stat = new StatFs(path.getPath());

			long blockSize = stat.getBlockSize();

			long availableBlocks = stat.getAvailableBlocks();

			return Formatter.formatFileSize(context, availableBlocks * blockSize);

		} else {

			return "";

		}

	}



	public static String getTotalExternalMemorySize(Context context) {

		if (externalMemoryAvailable()) {

			File path = Environment.getExternalStorageDirectory();

			StatFs stat = new StatFs(path.getPath());

			long blockSize = stat.getBlockSize();

			long totalBlocks = stat.getBlockCount();

			return Formatter.formatFileSize(context, totalBlocks * blockSize);

		} else {

			return "";

		}

	}



	public static String getUsedExternalMemorySize(Context context) {

		if (externalMemoryAvailable()) {

			File path = Environment.getExternalStorageDirectory();

			StatFs stat = new StatFs(path.getPath());

			long blockSize = stat.getBlockSize();

			long totalBlocks = stat.getBlockCount();

			long availableBlocks = stat.getAvailableBlocks();

			return Formatter.formatFileSize(context, (totalBlocks - availableBlocks) * blockSize);

		} else {

			return "";

		}

	}
