【Android】获取手机中已安装apk文件信息(PackageInfo、ResolveInfo)(应用图片、应用名、包名等)

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

view plaincopy to clipboardprint?
PackageManager packageManager = this.getPackageManager(); 
List<PackageInfo> packageInfoList = packageManager.getInstalledPackages(0); 
PackageManager packageManager = this.getPackageManager();
List<PackageInfo> 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，也包括了系统预装的应用软件的信息，要区分这两类软件可使用以下方法:

a.从packageInfoList获取的packageInfo，再通过packageInfo.applicationInfo获取applicationInfo。

b.判断(applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM)的值，该值大于0时，表示获取的应用为系统预装的应用，反之则为手动安装的应用。

大家可以看下代码，说明已经写在注释中。

获取应用的代码:

view plaincopy to clipboardprint?
/**
 * 查询手机内非系统应用
 * @param context
 * @return
 */ 
public static List<PackageInfo> getAllApps(Context context) { 
    List<PackageInfo> apps = new ArrayList<PackageInfo>(); 
    PackageManager pManager = context.getPackageManager(); 
    //获取手机内所有应用  
    List<PackageInfo> paklist = pManager.getInstalledPackages(0); 
    for (int i = 0; i < paklist.size(); i++) { 
        PackageInfo pak = (PackageInfo) paklist.get(i); 
        //判断是否为非系统预装的应用程序  
        if ((pak.applicationInfo.flags & pak.applicationInfo.FLAG_SYSTEM) <= 0) { 
            // customs applications  
            apps.add(pak); 
        } 
    } 
    return apps; 
} 
 /**
  * 查询手机内非系统应用
  * @param context
  * @return
  */
 public static List<PackageInfo> getAllApps(Context context) {
  List<PackageInfo> apps = new ArrayList<PackageInfo>();
  PackageManager pManager = context.getPackageManager();
  //获取手机内所有应用
  List<PackageInfo> paklist = pManager.getInstalledPackages(0);
  for (int i = 0; i < paklist.size(); i++) {
   PackageInfo pak = (PackageInfo) paklist.get(i);
   //判断是否为非系统预装的应用程序
   if ((pak.applicationInfo.flags & pak.applicationInfo.FLAG_SYSTEM) <= 0) {
    // customs applications
    apps.add(pak);
   }
  }
  return apps;
 }

 

获取图片、应用名、包名:

 

view plaincopy to clipboardprint?
PackageManager pManager = MessageSendActivity.this.getPackageManager(); 
List<PackageInfo> appList  = Utils.getAllApps(MessageSendActivity.this); 
 
for(int i=0;i<appList.size();i++) { 
    PackageInfo pinfo = appList.get(i); 
    ShareItemInfo shareItem = new ShareItemInfo(); 
    //set Icon  
 shareItem.setIcon(pManager.getApplicationIcon(pinfo.applicationInfo)); 
    //set Application Name  
    shareItem.setLabel(pManager.getApplicationLabel(pinfo.applicationInfo).toString()); 
    //set Package Name   
    shareItem.setPackageName(pinfo.applicationInfo.packageName); 
     
} 
                     PackageManager pManager = MessageSendActivity.this.getPackageManager();
                     List<PackageInfo> appList  = Utils.getAllApps(MessageSendActivity.this);
                    
                     for(int i=0;i<appList.size();i++) {
                      PackageInfo pinfo = appList.get(i);
                      ShareItemInfo shareItem = new ShareItemInfo();
                      //set Icon
                      shareItem.setIcon(pManager.getApplicationIcon(pinfo.applicationInfo));
                      //set Application Name
                      shareItem.setLabel(pManager.getApplicationLabel(pinfo.applicationInfo).toString());
                      //set Package Name
                      shareItem.setPackageName(pinfo.applicationInfo.packageName);
                      
                     }

其中 ShareItemInfo 类是我本地自定义的，各位可以忽略！

另为，有人可能在找 分享应用列表，在此一并说下吧。

获取支持分享的应用的代码：

view plaincopy to clipboardprint?
/**
 * 查询手机内所有支持分享的应用
 * @param context
 * @return
 */ 
public static List<ResolveInfo> getShareApps(Context context){ 
    List<ResolveInfo> mApps = new ArrayList<ResolveInfo>();   
    Intent intent=new Intent(Intent.ACTION_SEND,null);   
    intent.addCategory(Intent.CATEGORY_DEFAULT);   
    intent.setType("text/plain");   
    PackageManager pManager = context.getPackageManager(); 
    mApps = pManager.queryIntentActivities(intent,PackageManager.COMPONENT_ENABLED_STATE_DEFAULT);   
     
    return mApps;   
} 
 /**
  * 查询手机内所有支持分享的应用
  * @param context
  * @return
  */
 public static List<ResolveInfo> getShareApps(Context context){
     List<ResolveInfo> mApps = new ArrayList<ResolveInfo>(); 
     Intent intent=new Intent(Intent.ACTION_SEND,null); 
     intent.addCategory(Intent.CATEGORY_DEFAULT); 
     intent.setType("text/plain"); 
     PackageManager pManager = context.getPackageManager();
     mApps = pManager.queryIntentActivities(intent,PackageManager.COMPONENT_ENABLED_STATE_DEFAULT); 
    
     return mApps; 
 }

由于该方法，返回的并不是 PackageInfo 对象。而是 ResolveInfo。因此获取图片、应用名、包名的方法不一样，如下：

view plaincopy to clipboardprint?
PackageManager pManager = MessageSendActivity.this.getPackageManager(); 
 
/*********************查询手机内所有支持分享的应用*********************/ 
List<ResolveInfo> resolveList  = Utils.getShareApps(MessageSendActivity.this); 
 
for(int i=0;i<resolveList.size();i++) { 
    ResolveInfo resolve = resolveList.get(i); 
    ShareItemInfo shareItem = new ShareItemInfo(); 
    //set Icon  
 shareItem.setIcon(resolve.loadIcon(pManager)); 
    //set Application Name  
    shareItem.setLabel(resolve.loadLabel(pManager).toString()); 
    //set Package Name   
    shareItem.setPackageName(resolve.activityInfo.packageName); 
     
} 
                     PackageManager pManager = MessageSendActivity.this.getPackageManager();
                    
                     /*********************查询手机内所有支持分享的应用*********************/
                     List<ResolveInfo> resolveList  = Utils.getShareApps(MessageSendActivity.this);
                    
                     for(int i=0;i<resolveList.size();i++) {
                      ResolveInfo resolve = resolveList.get(i);
                      ShareItemInfo shareItem = new ShareItemInfo();
                      //set Icon
                      shareItem.setIcon(resolve.loadIcon(pManager));
                      //set Application Name
                      shareItem.setLabel(resolve.loadLabel(pManager).toString());
                      //set Package Name
                      shareItem.setPackageName(resolve.activityInfo.packageName);
                      
                     }

总结：

 

 

通过 PackageInfo  获取具体信息方法：

 

包名获取方法：packageInfo.packageName

icon获取获取方法：packageManager.getApplicationIcon(applicationInfo)

应用名称获取方法：packageManager.getApplicationLabel(applicationInfo)

使用权限获取方法：packageManager.getPackageInfo(packageName,PackageManager.GET_PERMISSIONS)

.requestedPermissions

 

通过 ResolveInfo 获取具体信息方法：

 

包名获取方法：resolve.activityInfo.packageName

icon获取获取方法：resolve.loadIcon(packageManager)

应用名称获取方法：resolve.loadLabel(packageManager).toString()
