android packageinfo
As I mentioned ApplicationInfo is actually an attribute/field of PackageInfo which itself happens to be a complex object and has its own methods/fields. In which cases ApplicationInfo is used and when PackageInfo is used? To access information within app,Change PackageInfo packageInfo=packageManager.getPackageInfo(getContext().getPackageName(), PackageManager.GET_ACTIVITIES);. to PackageInfo packageInfo=packageManager.getPackageInfo(getContext().getPackageName(), 0);. ,so permissionInfo will have the attributes in manifest tag in manifest for e.g. <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.android.androidtest" android:icon="@mipmap/ic_launcher&qu, Sample code: try PackageInfo packageInfo = getPackageManager().getPackageInfo(getPackageName(), 0); return packageInfo.versionName; } catch (NameNotFoundException e) //Handle exception }., PackageInfo 我们通过下面的方法获得PackageInfo对象信息： getInstalledPackages(int flags) 参数flags有如下的值： GET_ACTIVITIES ：值为1.如果想获得所有标签的信息,需要传入这个值.然后通过PackageInfo.GET_GIDS:值为256.获得group id的信息.GET_CONF., 許多時應用軟件都提供一個About Me選項, 從而檢視軟件版本. 檢視軟件版本 在Android可以使用下面程序代碼: PackageInfo packageInfo = getPackageManager().getPackageInfo(getPackageName(), 0); myVersionCode = packageInfo.versionCode; myVersionName = packageInfo.versionName; 返回的數據 ..., 我们知道程序信息存储在Androidmanifest.xml文件中SDK提供了PackageInfo类，该类包含了从Androidmanifest.xml文件中收集的所有信息。 查看PackageInfo源码PackageInfo的子类ApplicationInfo中封装了:程序名称程序图标等信息如何获取这些信息的呢？查看ApplicationInfo源码ApplicationInfo...,setLongVersionCode.

Set the full version code in this PackageInfo, updating versionCode with the lower bits. ,通過以上方法，可以得到手機中安裝的所有應用程式，既包括了手動安裝的apk包的資訊，也包括了系統預裝的應用軟體的資訊，要區分這兩類軟體可使用以下方法: a.從packageInfoList獲取的packageInfo，再通過packageInfo.applicationInfo獲取applicationInfo。 b.判斷(applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM)的值， ... ,众所周知，通过PackageManager可以获取手机端已安装的apk文件的信息，具体代码如下PackageManager packageManager = this.getPackageManager(); List packageInfoList = packageManager.getInstalledPackages(0); 通过以上方法，可以得到手机中安装的所有应用程序，既包括了手动安装的apk包的信息，也包括了系统预装 ...
