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 "";}}
