  • 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 "";
    		}
    	}
