获取未安装apk的软件包信息

方法：

/** 获取未安装的APK信息  * @param context  * @param archiveFilePath APK文件的路径。如：/sdcard /download/XX.apk  */  public void getUninatllApkInfo(Context context, String archiveFilePath){      PackageManager pm = context.getPackageManager();      PackageInfo info = pm.getPackageArchiveInfo(archiveFilePath, PackageManager.GET_ACTIVITIES);      if(info != null){          ApplicationInfo appInfo = info.applicationInfo;          String appName = pm.getApplicationLabel(appInfo).toString();          String packageName = appInfo.packageName;          Drawable icon = pm.getApplicationIcon(appInfo);      }  } 

PackageManager是个非常好的东西，其他的详细的细节等日后有时间整理

PackageManager的功能：

•安装，卸载应用
•查询permission相关信息
•查询Application相关信息(application，activity，receiver，service，provider及相应属性等）
•查询已安装应用
•增加，删除permission
•清除用户数据、缓存，代码段等

 

我们可以用PackageManager来显示系统安装的应用程序列表或者系统程序列表

废话先不多说

现在看看效果图

如果要只是显示用户安装的应用程序的话，可以直接使用

如果用户要显示包括系统程序的话，需要取出if的判断部分，上面代码里面有标识
