Android獲取Apk文件圖標信息

/** 
* 獲取apk包的信息：版本號，名稱，圖標等 
* @param absPath apk包的絕對路徑 
* @param context  
*/  
public void apkInfo(String absPath,Context context) {  
          
    PackageManager pm = context.getPackageManager();  
    PackageInfo pkgInfo = pm.getPackageArchiveInfo(absPath,PackageManager.GET_ACTIVITIES);  
    if (pkgInfo != null) {  
        ApplicationInfo appInfo = pkgInfo.applicationInfo;  
        /* 必須加這兩句，不然下面icon獲取是default icon而不是應用包的icon */  
        appInfo.sourceDir = absPath;  
        appInfo.publicSourceDir = absPath;  
        String appName = pm.getApplicationLabel(appInfo).toString();// 得到應用名  
        String packageName = appInfo.packageName; // 得到包名  
        String version = pkgInfo.versionName; // 得到版本信息  
        /* icon1和icon2其實是一樣的 */  
        Drawable icon1 = pm.getApplicationIcon(appInfo);// 得到圖標信息  
        Drawable icon2 = appInfo.loadIcon(pm);  
        String pkgInfoStr = String.format("PackageName:%s, Vesion: %s, AppName: %s", packageName, version, appName);  
        Log.i(TAG, String.format("PkgInfo: %s", pkgInfoStr));  
    }
