1. Determine if the network is connected

Public boolean isNetworkConnected () {ConnectivityManager cm = (ConnectivityManager) getSystemService (Context. CONNECTIVITY_SERVICE); NetworkInfo ni = cm. getActiveNetworkInfo (); return ni! = Null & ni. isConnectedOrConnecting ();}

2. Determine the network type

/*** Get the current network type * @ return 0: No network 1: WIFI network 2: WAP network 3: NET Network */public int getNetworkType () {int netType = 0; connectivityManager connectivityManager = (ConnectivityManager) getSystemService (Context. CONNECTIVITY_SERVICE); NetworkInfo networkInfo = connectivityManager. getActiveNetworkInfo (); if (networkInfo = null) {return netType;} int nType = networkInfo. getType (); if (nType = ConnectivityManager. TYPE_MOB ILE) {String extraInfo = networkInfo. getExtraInfo (); if (! StringUtils. isEmpty (extraInfo) {if (extraInfo. toLowerCase (). equals ("cmnet") {netType = NETTYPE_CMNET;} else {netType = NETTYPE_CMWAP ;}} else if (nType = ConnectivityManager. TYPE_WIFI) {netType = NETTYPE_WIFI;} return netType ;}

3. Compare the mobile phone version

/*** Method for determining whether the current version is compatible with the Target version * @ param VersionCode * @ return */public static boolean isMethodsCompat (int VersionCode) {int currentVersion = android. OS. build. VERSION. SDK_INT; return currentVersion >=versioncode ;}

4. App installation package information

/*** Get App installation package information * @ return */public PackageInfo getPackageInfo () {PackageInfo info = null; try {info = getPackageManager (). getPackageInfo (getPackageName (), 0);} catch (NameNotFoundException e) {e. printStackTrace (System. err);} if (info = null) info = new PackageInfo (); return info ;}

5. Store basic application information

Public Properties get () {FileInputStream FCM = null; Properties props = new Properties (); try {// read the config // FCM = activity in the files directory. openFileInput (APP_CONFIG); // read configFile dirConf = mContext in the app_config directory. getDir (APP_CONFIG, Context. MODE_PRIVATE); FCM = new FileInputStream (dirConf. getPath () + File. separator + APP_CONFIG); props. load (FCM);} catch (Exception e) {} finally {try {FCM. close () ;}catch (Exception e) {}} return props;} private void setProps (Properties p) {FileOutputStream fos = null; try {// create config in the files Directory // fos = activity. openFileOutput (APP_CONFIG, Context. MODE_PRIVATE); // create the config in the (custom) app_config directory File dirConf = mContext. getDir (APP_CONFIG, Context. MODE_PRIVATE); File conf = new File (dirConf, APP_CONFIG); fos = new FileOutputStream (conf); p. store (fos, null); fos. flush ();} catch (Exception e) {e. printStackTrace ();} finally {try {fos. close () ;}catch (Exception e ){}}}

6. Read mobile phone and application-related information

String versionName = getPackageManager (). getPackageInfo (getPackageName (), 0 ). versionName; int versionCode = getPackageManager (). getPackageInfo (getPackageName (), 0 ). versionCode; String VERSION = android. OS. build. VERSION. RELEASE; // System version String MODEL = android. OS. build. MODEL; // The textView of the mobile phone MODEL. setText ("versionName" + versionName + "\ n" + "versionCode" + versionCode + "\ n" + "system VERSION" + VERSION + "\ n" + "mobile phone model" + MODEL );
