ApplicationInfo 存储信息放上来是方便查看

    static public String getAppLocalPathInDataApp(Context ctx,String packname){        PackageManager pm=ctx.getPackageManager();        try {            ApplicationInfo info = pm.getApplicationInfo(packname, 0);            Log.i(TAG,"getCodePath"+info.sourceDir);///data/app/com.palmv.wechatAuto-2.apk            Log.i(TAG,"sourceDir"+info.sourceDir); //Full path to the publicly available parts of sourceDir, including resources and manifest.        } catch (PackageManager.NameNotFoundException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }        return "";    }
