经典好文推荐,通过阅读本文,您将收获以下知识点:

一、 获取手机基本信息(厂商、型号等参数)
二、设备信息获取实现图
三、 获取手机设备 宽、高、IMEI 信息
四、 获取手机厂商名、产品名、手机品牌、手机型号、主板名、设备名
五、获取手机硬件名、SDK版本、android版本 、语言支持、默认语言

下面将讲解以上信息的获取方法。

以小米手机为例,手机常用的基本信息可以在Settings--> About Phone中看到,
例如下图:

小米手机设备信息图

那么如何获取这些设备信息呢? Android中 通常通过 android.os.Build类方法可以获取更多手机设备信息。

获取手机IMEI、宽、高、是否有SD卡,RAM、ROM、SD卡、是否联网、网络类型

默认语言,设备名,型号、厂商、Fingerprint、Android 版本、SDK版本、Google 安全patch、发布时间、版本类型、用户名

产品名、ID、产品名、主板名

获取手机宽、高、IMEI信息方法如下:

    /**
* 获取设备宽度(px)
*
*/

public static int getDeviceWidth(Context context) {
return context.getResources().getDisplayMetrics().widthPixels;
}

/**
* 获取设备高度(px)
*/

public static int getDeviceHeight(Context context) {
return context.getResources().getDisplayMetrics().heightPixels;
}

/**
* 获取设备的唯一标识, 需要 “android.permission.READ_Phone_STATE”权限
*/

public static String getIMEI(Context context) {
TelephonyManager tm = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
String deviceId = tm.getDeviceId();
if (deviceId == null) {
return "UnKnown";
} else {
return deviceId;
}
}

注意: 获取IMEI 需要获取手机状态权限

 <!-- 读取手机IMEI的设备权限 -->
<uses-permission android:name="android.permission.READ_PHONE_STATE" />

如果是Android 6.0 之后的代码请使用动态申请权限的方法申请权限,否认会报安全异常的错误SecurityException,进而导致运行报错。

如需了解更多 系统安全权限的内容,请看 之前写的文章 Android 系统权限使用详解

获取手机厂商名、产品名、手机品牌、手机型号、主板名、设备名的方法如下:

    /**
* 获取厂商名
* **/

public static String getDeviceManufacturer() {
return android.os.Build.MANUFACTURER;
}

/**
* 获取产品名
* **/

public static String getDeviceProduct() {
return android.os.Build.PRODUCT;
}

/**
* 获取手机品牌
*/

public static String getDeviceBrand() {
return android.os.Build.BRAND;
}

/**
* 获取手机型号
*/

public static String getDeviceModel() {
return android.os.Build.MODEL;
}

/**
* 获取手机主板名
*/

public static String getDeviceBoard() {
return android.os.Build.BOARD;
}

/**
* 设备名
* **/

public static String getDeviceDevice() {
return android.os.Build.DEVICE;
}

/**
*
*
* fingerprit 信息
* **/

public static String getDeviceFubgerprint() {
return android.os.Build.FINGERPRINT;
}

获取手机硬件名、SDK版本android版本 、语言支持、默认语言等方法如下:

    /**
* 硬件名
*
* **/

public static String getDeviceHardware() {
return android.os.Build.HARDWARE;
}

/**
* 主机
*
* **/

public static String getDeviceHost() {
return android.os.Build.HOST;
}

/**
*
* 显示ID
* **/

public static String getDeviceDisplay() {
return android.os.Build.DISPLAY;
}

/**
* ID
*
* **/

public static String getDeviceId() {
return android.os.Build.ID;
}

/**
* 获取手机用户名
*
* **/

public static String getDeviceUser() {
return android.os.Build.USER;
}

/**
* 获取手机 硬件序列号
* **/

public static String getDeviceSerial() {
return android.os.Build.SERIAL;
}

/**
* 获取手机Android 系统SDK
*
* @return
*/

public static int getDeviceSDK() {
return android.os.Build.VERSION.SDK_INT;
}

/**
* 获取手机Android 版本
*
* @return
*/

public static String getDeviceAndroidVersion() {
return android.os.Build.VERSION.RELEASE;
}

/**
* 获取当前手机系统语言。
*/

public static String getDeviceDefaultLanguage() {
return Locale.getDefault().getLanguage();
}

/**
* 获取当前系统上的语言列表(Locale列表)
*/

public static String getDeviceSupportLanguage() {
Log.e("wangjie", "Local:" + Locale.GERMAN);
Log.e("wangjie", "Local:" + Locale.ENGLISH);
Log.e("wangjie", "Local:" + Locale.US);
Log.e("wangjie", "Local:" + Locale.CHINESE);
Log.e("wangjie", "Local:" + Locale.TAIWAN);
Log.e("wangjie", "Local:" + Locale.FRANCE);
Log.e("wangjie", "Local:" + Locale.FRENCH);
Log.e("wangjie", "Local:" + Locale.GERMANY);
Log.e("wangjie", "Local:" + Locale.ITALIAN);
Log.e("wangjie", "Local:" + Locale.JAPAN);
Log.e("wangjie", "Local:" + Locale.JAPANESE);
return Locale.getAvailableLocales().toString();
}

SD卡信息

1.判断SD是否挂载方法

判断SD是否挂载方法如下:

    /**
* 判断SD是否挂载
*/

public static boolean isSDCardMount() {
return Environment.getExternalStorageState().equals(
Environment.MEDIA_MOUNTED);
}

2. 获取SD 存储信息的方法

获取SD 存储信息的方法如下:

/**
* 获取手机存储 ROM 信息
*
* type: 用于区分内置存储于外置存储的方法
*
* 内置SD卡 :INTERNAL_STORAGE = 0;
*
* 外置SD卡: EXTERNAL_STORAGE = 1;
* **/

public static String getStorageInfo(Context context, int type) {

String path = getStoragePath(context, type);
/**
* 无外置SD 卡判断
* **/

if (isSDCardMount() == false || TextUtils.isEmpty(path) || path == null) {
return "无外置SD卡";
}

File file = new File(path);
StatFs statFs = new StatFs(file.getPath());
String stotageInfo;

long blockCount = statFs.getBlockCountLong();
long bloackSize = statFs.getBlockSizeLong();
long totalSpace = bloackSize * blockCount;

long availableBlocks = statFs.getAvailableBlocksLong();
long availableSpace = availableBlocks * bloackSize;

stotageInfo = "可用/总共:"
+ Formatter.formatFileSize(context, availableSpace) + "/"
+ Formatter.formatFileSize(context, totalSpace);

return stotageInfo;

}

3. 获取手机ROM (内置存储,外置存储)存储路径的方法

获取手机ROM 存储信息的方法如下:

/**
* 使用反射方法 获取手机存储路径
*
* **/

public static String getStoragePath(Context context, int type) {

StorageManager sm = (StorageManager) context
.getSystemService(Context.STORAGE_SERVICE);
try {
Method getPathsMethod = sm.getClass().getMethod("getVolumePaths",
null);
String[] path = (String[]) getPathsMethod.invoke(sm, null);

switch (type) {
case INTERNAL_STORAGE:
return path[type];
case EXTERNAL_STORAGE:
if (path.length > 1) {
return path[type];
} else {
return null;
}

default:
break;
}

} catch (Exception e) {
e.printStackTrace();
}
return null;
}

/**
* 获取 手机 RAM 信息 方法 一
* */

public static String getTotalRAM(Context context) {
long size = 0;
ActivityManager activityManager = (ActivityManager) context
.getSystemService(context.ACTIVITY_SERVICE);
MemoryInfo outInfo = new MemoryInfo();
activityManager.getMemoryInfo(outInfo);
size = outInfo.totalMem;

return Formatter.formatFileSize(context, size);
}

/**
* 手机 RAM 信息 方法 二
* */

public static String getTotalRAMOther(Context context) {
String path = "/proc/meminfo";
String firstLine = null;
int totalRam = 0;
try {
FileReader fileReader = new FileReader(path);
BufferedReader br = new BufferedReader(fileReader, 8192);
firstLine = br.readLine().split("\\s+")[1];
br.close();
} catch (Exception e) {
e.printStackTrace();
}
if (firstLine != null) {

totalRam = (int) Math.ceil((new Float(Float.valueOf(firstLine)
/ (1024 * 1024)).doubleValue()));

long totalBytes = 0;

}

return Formatter.formatFileSize(context, totalRam);
}

/**
* 获取 手机 可用 RAM
* */

public static String getAvailableRAM(Context context) {
long size = 0;
ActivityManager activityManager = (ActivityManager) context
.getSystemService(context.ACTIVITY_SERVICE);
MemoryInfo outInfo = new MemoryInfo();
activityManager.getMemoryInfo(outInfo);
size = outInfo.availMem;

return Formatter.formatFileSize(context, size);
}

1.RAM:

运行时内存,此大小直接决定手机运行的流畅度,相当于电脑内存。

2.ROM :

手机存储(分内置SD卡,外置SD卡),此大小直接决定着手机可以存储资源的大小,相当于电脑硬盘。

以红米手机为例:
RAM= 1904716KB= 1.82G

红米4 手机 RAM、ROM存储信息

红米4 memory 信息 meminfo

3.获取 RAM存储信息的方法如下:

    /**
* 获取 手机 RAM 信息
* */

public static String getRAMInfo(Context context) {
long totalSize = 0;
long availableSize = 0;

ActivityManager activityManager = (ActivityManager) context
.getSystemService(context.ACTIVITY_SERVICE);

MemoryInfo memoryInfo = new MemoryInfo();
activityManager.getMemoryInfo(memoryInfo);
totalSize = memoryInfo.totalMem;
availableSize = memoryInfo.availMem;

return "可用/总共:" + Formatter.formatFileSize(context, availableSize)
+ "/" + Formatter.formatFileSize(context, totalSize);
}

4. 获取手机ROM存储信息的方法如下:

/**
* 获取手机存储 ROM 信息
*
* type: 用于区分内置存储于外置存储的方法
*
* 内置SD卡 :INTERNAL_STORAGE = 0;
*
* 外置SD卡: EXTERNAL_STORAGE = 1;
* **/

public static String getStorageInfo(Context context, int type) {

String path = getStoragePath(context, type);
/**
* 无外置SD 卡判断
* **/

if (isSDCardMount() == false || TextUtils.isEmpty(path) || path == null) {
return "无外置SD卡";
}

File file = new File(path);
StatFs statFs = new StatFs(file.getPath());
String stotageInfo;

long blockCount = statFs.getBlockCountLong();
long bloackSize = statFs.getBlockSizeLong();
long totalSpace = bloackSize * blockCount;

long availableBlocks = statFs.getAvailableBlocksLong();
long availableSpace = availableBlocks * bloackSize;

stotageInfo = "可用/总共:"
+ Formatter.formatFileSize(context, availableSpace) + "/"
+ Formatter.formatFileSize(context, totalSpace);

return stotageInfo;

}
