各种获取应用信息小功能，做个笔记：

  /**     * 获取版本名     *     * @param context     * @return 获取版本名     */    public static String getVersionName(Context context) {        PackageInfo packageInfo = null;        try {            packageInfo = context.getPackageManager().getPackageInfo(context.getPackageName(), 0);            return packageInfo.versionName;        } catch (NameNotFoundException e) {            e.printStackTrace();        }        return null;    }

   /**     * 获取版本号     *     * @param context     * @return     */    public static int getVersionCode(Context context) {        PackageInfo packageInfo = null;        try {            packageInfo = context.getPackageManager().getPackageInfo(context.getPackageName(), 0);            return packageInfo.versionCode;        } catch (NameNotFoundException e) {            e.printStackTrace();        }        return 0;    }

 /**     * 获取安装本应用的手机及手机卡信息     *     * @param context     * @return     */    public static String getPhoneInfo(Context context) {        /**         * imei,移动设备标识码         */        String device_id = "";        /**         *手机号码标识         */        String imsi = "";        /**         * 手机型号         */        String phoneModel = "";        /**         * 手机操作系统版本         */        String phoneVersion = "";        /**         * 手机号码         */        String phoneNum = "";        /**         * 手机物理标识         */        String mac = "";        try {            org.json.JSONObject json = new org.json.JSONObject();            android.telephony.TelephonyManager tm = (android.telephony.TelephonyManager) context                    .getSystemService(Context.TELEPHONY_SERVICE);            if (checkPermission(context, Manifest.permission.READ_PHONE_STATE)) {                device_id = tm.getDeviceId();                imsi = tm.getSubscriberId();                phoneNum = tm.getLine1Number();                phoneModel = android.os.Build.MODEL;                phoneVersion = android.os.Build.VERSION.RELEASE;            }            android.net.wifi.WifiManager wifi = (android.net.wifi.WifiManager) context                    .getSystemService(Context.WIFI_SERVICE);            mac = wifi.getConnectionInfo().getMacAddress();            if (TextUtils.isEmpty(device_id)) {                device_id = mac;            }            if (TextUtils.isEmpty(device_id)) {//如果Android pad没有IMEI                device_id = android.provider.Settings.Secure.getString(context.getContentResolver(),                        android.provider.Settings.Secure.ANDROID_ID);            }            json.put("mac", mac);            json.put("imei", device_id);            json.put("imsi", imsi);            json.put("phoneModel", phoneModel);            json.put("phoneVersion", phoneVersion);            json.put("phoneNum", phoneNum);            return json.toString();        } catch (Exception e) {            e.printStackTrace();        }        return null;    }    private static boolean checkPermission(Context context, String permission) {        boolean result = false;        if (Build.VERSION.SDK_INT >= 23) {            if (context.checkSelfPermission(permission) == PackageManager.PERMISSION_GRANTED) {                result = true;            }        } else {            PackageManager pm = context.getPackageManager();            if (pm.checkPermission(permission, context.getPackageName()) == PackageManager.PERMISSION_GRANTED) {                result = true;            }        }        return result;    }

获取手机上安装的所有应用：

/** * 获取手机应用程序 * Created by songyaru on 16/9/29. */public class AppInfoService {    private Context context;    private PackageManager pm;    public AppInfoService(Context context) {        this.context = context;        pm = context.getPackageManager();    }    /**     * 得到手机中所有的应用程序信息     *     * @return     */    public List<AppInfo> getAppInfos() {        //创建要返回的集合对象        List<AppInfo> appInfos = new ArrayList();        //获取手机中所有安装的应用集合        List<ApplicationInfo> applicationInfos = pm.getInstalledApplications(PackageManager.GET_UNINSTALLED_PACKAGES);        //遍历所有的应用集合        for (ApplicationInfo info : applicationInfos) {            AppInfo appInfo = new AppInfo();            //获取应用程序的图标            Drawable app_icon = info.loadIcon(pm);            appInfo.setApp_icon(app_icon);            //获取应用的名称            String app_name = info.loadLabel(pm).toString();            appInfo.setApp_name(app_name);            //获取应用的包名            String packageName = info.packageName;            appInfo.setPackagename(packageName);            try {                //获取应用的版本号//                PackageInfo packageInfo = pm.getPackageInfo(packageName, 0);                PackageInfo packageInfo = pm.getPackageInfo(packageName, PackageManager.GET_ACTIVITIES                        | PackageManager.GET_PERMISSIONS);                String app_version = packageInfo.versionName;                appInfo.setApp_version(app_version);                //获取应用的使用权限                String[] app_permission = packageInfo.requestedPermissions;                Log.e("appinfo", app_permission.length + "=数量");                appInfo.setAppPremission(app_permission);            } catch (PackageManager.NameNotFoundException e) {                e.printStackTrace();            }            //判断应用程序是否是用户程序            boolean isUserApp = filterApp(info);            appInfo.setIsUserApp(isUserApp);            appInfos.add(appInfo);        }        return appInfos;    }    //判断应用程序是否是用户程序    public boolean filterApp(ApplicationInfo info) {        //原来是系统应用，用户手动升级        if ((info.flags & ApplicationInfo.FLAG_UPDATED_SYSTEM_APP) != 0) {            return true;            //用户自己安装的应用程序        } else if ((info.flags & ApplicationInfo.FLAG_SYSTEM) == 0) {            return true;        }        return false;    }}

用与存储应用信息的javaBean：

/** * Created by songyaru on 16/9/29. * 获取的应用基本信息实体类 */public class AppInfo {    //图标    private Drawable app_icon;    //应用名称    private String app_name;    //应用版本号    private String app_version;    //应用包名    private String packagename;    //是否是用户app    private boolean isUserApp;    //应用所需权限    private String[] appPremission;    public AppInfo() {        super();    }    public AppInfo(Drawable app_icon, String app_name, String app_version,                   String packagename) {        super();        this.app_icon = app_icon;        this.app_name = app_name;        this.app_version = app_version;        this.packagename = packagename;    }    public AppInfo(Drawable app_icon, String app_name, String app_version,                   String packagename, boolean isUserApp, String[] appPremission) {        super();        this.app_icon = app_icon;        this.app_name = app_name;        this.app_version = app_version;        this.packagename = packagename;        this.isUserApp = isUserApp;        this.appPremission = appPremission;    }    public Drawable getApp_icon() {        return app_icon;    }    public void setApp_icon(Drawable app_icon) {        this.app_icon = app_icon;    }    public String getApp_name() {        return app_name;    }    public void setApp_name(String app_name) {        this.app_name = app_name;    }    public String getApp_version() {        return app_version;    }    public void setApp_version(String app_version) {        this.app_version = app_version;    }    public String getPackagename() {        return packagename;    }    public void setPackagename(String packagename) {        this.packagename = packagename;    }    public boolean isUserApp() {        return isUserApp;    }    public void setIsUserApp(boolean isUserApp) {        this.isUserApp = isUserApp;    }    public String[] getAppPremission() {        return appPremission;    }    public void setAppPremission(String[] appPremission) {        this.appPremission = appPremission;    }    @Override    public String toString() {        return "AppInfo{" +                "app_icon=" + app_icon +                ", app_name='" + app_name + '\'' +                ", app_version='" + app_version + '\'' +                ", packagename='" + packagename + '\'' +                ", isUserApp=" + isUserApp +                ", appPremission=" + Arrays.toString(appPremission) +                '}';    }}
