    @Override  
    public void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);         
        setContentView(R.layout.main);      
        String archiveFilePath="sdcard/download/Law.apk";//安装包路径  
        PackageManager pm = 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;  //得到安装包名称  
            String version=info.versionName;       //得到版本信息       
            Toast.makeText(test4.this, "packageName:"+packageName+";version:"+version, Toast.LENGTH_LONG).show();  
            Drawable icon = pm.getApplicationIcon(appInfo);//得到图标信息  
            TextView tv = (TextView)findViewById(R.id.tv); //显示图标  
            tv.setBackgroundDrawable(icon);  
        }    
    }  
  
}
