android 获取设备信息

1：获取设备当前电量

 /**
     * 获取手机电量 不需要权限
     *
     * @param context
     * @return
     */
    public static int getBattery(Context context) {
        int ret = 0;
        try {
            Intent intent = context.registerReceiver(null, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
            if (intent != null) {
                int level = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
                int scale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, -1);
                if (level >= 0 && scale > 0) {
                    ret = level * 100 / scale;
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return ret;
    }

2：获取当前存储的剩余量

  public static long getStorageAvailable() {
        long size = 0;
        StatFs statFs = new StatFs(Environment.getExternalStorageDirectory().getPath());
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR2) {
            size = statFs.getAvailableBytes() / 1024 / 1024 / 1024;
        }
        return size;
    }

3：获取android版本

  public static String getAndroidVersion(){
        return Build.VERSION.RELEASE;
    }

4：获取手机型号

   public static String getModel(){
        return Build.MODEL;
    }

5：获取手机厂商

public static String getManufacturer(){
        return Build.MANUFACTURER;
    }

6：判断手机或者平板

    public static String getOsModel(Context context) {
        String phone = null;
        try {
            TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
            phone = telephonyManager.getPhoneType() != TelephonyManager.PHONE_TYPE_NONE ? "android phone" : "android pad";
        } catch (Exception e) {
            e.printStackTrace();
        }

        return phone;
    }
