一、屏幕分辨率Display display = getWindowManager().getDefaultDisplay();Point size = new Point();display.getSize(size);int width = size.x;int height = size.y;
或者:
DisplayMetrics metrics = new DisplayMetrics();getWindowManager().getDefaultDisplay().getMetrics(metrics);int width = metrics.widthPixels;int height = metrics.heightPixels
上面的代码是要在能获取到
Activity
的情况下使用的,如果无法获取到
Activity
,则可以使用一下的代码:
WindowManager wm = (WindowManager)context.getSystemService(Context.WINDOW_SERVICE);Display display = wm.getDefaultDisplay();Point point = new Point();display.getSize(point);int width = point.x;int height = point.y;
二、屏幕尺寸DisplayMetrics dm = new DisplayMetrics();getWindowManager().getDefaultDisplay().getMetrics(dm);int width=dm.widthPixels;int height=dm.heightPixels;int dens=dm.densityDpi;double wi=(double)width/(double)dens;double hi=(double)height/(double)dens;double x = Math.pow(wi,2);double y = Math.pow(hi,2);double screenInches = Math.sqrt(x+y);
同样,上面的代码需要在能获取到Activity。
三、获取app名称public static String getAppName(Context context) {String appName = "";try {PackageManager packageManager = context.getPackageManager();ApplicationInfo applicationInfo = packageManager.getApplicationInfo(context.getPackageName(), 0);appName = (String) packageManager.getApplicationLabel(applicationInfo);} catch (PackageManager.NameNotFoundException e) {e.printStackTrace();}return appName;}
四、获取设备厂商和设备名称信息// 设备厂商String brand = Build.BRAND;// 设备名称String model = Build.MODEL;
获取DeviceID,SIM和IMSITelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);String deviceId = tm.getDeviceId();String sim = tm.getSimSerialNumber();String imsi = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE).getSubscriberId();
注意需要在
AndroidManifest
中添加权限
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
五、获取网络状态public static String getAPNType(Context context) {//结果返回值String netType = "nono_connect";//获取手机所有连接管理对象ConnectivityManager manager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);//获取NetworkInfo对象NetworkInfo networkInfo = manager.getActiveNetworkInfo();//NetworkInfo对象为空 则代表没有网络if (networkInfo == null) {return netType;}//否则 NetworkInfo对象不为空 则获取该networkInfo的类型int nType = networkInfo.getType();if (nType == ConnectivityManager.TYPE_WIFI) {//WIFInetType = "wifi";} else if (nType == ConnectivityManager.TYPE_MOBILE) {int nSubType = networkInfo.getSubtype();TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);//4Gif (nSubType == TelephonyManager.NETWORK_TYPE_LTE&& !telephonyManager.isNetworkRoaming()) {netType = "4G";} else if (nSubType == TelephonyManager.NETWORK_TYPE_UMTS || nSubType == TelephonyManager.NETWORK_TYPE_HSDPA || nSubType == TelephonyManager.NETWORK_TYPE_EVDO_0 && !telephonyManager.isNetworkRoaming()) {netType = "3G";//2G 移动和联通的2G为GPRS或EGDE,电信的2G为CDMA} else if (nSubType == TelephonyManager.NETWORK_TYPE_GPRS || nSubType == TelephonyManager.NETWORK_TYPE_EDGE || nSubType == TelephonyManager.NETWORK_TYPE_CDMA && !telephonyManager.isNetworkRoaming()) {netType = "2G";} else {netType = "2G";}}return netType;}
六、判断设备是否root网上有很多判断方法,但有些会在界面上弹窗提示获取权限,下面介绍一种无需弹窗判断设备是否root的方法:
/** 判断手机是否root,不弹出root请求框<br/> */public static boolean isRoot() {String binPath = "/system/bin/su";String xBinPath = "/system/xbin/su";if (new File(binPath).exists() && isExecutable(binPath))return true;if (new File(xBinPath).exists() && isExecutable(xBinPath))return true;return false;}private static boolean isExecutable(String filePath) {Process p = null;try {p = Runtime.getRuntime().exec("ls -l " + filePath);// 获取返回内容BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream()));String str = in.readLine();if (str != null && str.length() >= 4) {char flag = str.charAt(3);if (flag == "s" || flag == "x")return true;}} catch (IOException e) {e.printStackTrace();} finally {if (p != null) {p.destroy();}}return false;}
