MemoCase: application for mobile phones       PDF

MemoCase is an application for mobile phones and other mobile devices managing your notes, memos, ideas, etc.

MemoCase is developed in programming language Java and runs in J2ME framework.

MemoCase installation pack consists of 2 files:

  • JAR file ( MemoCase .jar ) - containing the application installation itself
  • JAD ( MemoCase.jad ) - containing the product description and digital signature<
MemoCase installation procedure is similar to other Java/J2ME programs installation procedures.

Installation of MemoCase from personal computer

After having received the installation files of MemoCase, the application can be installed from personal computer by using:

  • USB cable connection
  • Bluetooth wireless connection
  • infrared wireless connection

To begin the installation please start on your PC your mobile phone access program ( in most cases a version of PC Suite program ) and connect in any possible way your mobile phone to the PC.

Then select from the main panel of your mobile phone access application ( PC Suite ) the applications installations utility ( Install applications ).

The application installation utility allows you to find and select the MemoCase installation files on your computer ( JAR file ). Please start the installation of MemoCase by clicking on the arrow button.

After having started the installation procedure your mobile phone takes control of further steps. The user may respond on the mobile phone keyboard to its requests.

MemoCase is digitally signed by using digital certificate of MP System LLC ( Sp. z o.o. ) to let the user and its mobile phone unambiguously identify the application's code. In some older mobile phone models the proper root certificate required to verify the signature may be missing. In such case we advise to switch on the option of online certificate verification, which uses online internet connection to verify the digital signature.

Some mobile phone models are delivered without attached PC access or service utility. In such case you may connect your mobile phone to your computer in file retrieving mode, and simply copy the MemoCase installation files from your computer to your mobile phone's storage. Then the application installation utility on your mobile phone starts automatically or you may start the installation by selecting and "opening" the MemoCase JAR file on your mobile phone.

During installation procedure the mobile phone asks, where to install the installed application: either in the phone's memory or on a memory card ( if memory card is attached to your mobile phone ).

Please select the phone's internal memory for MemoCase to install. Otherwise MemoCase might be not available after reset of your mobile phone.

MemoCase installation requires appx. 0,5 MB of phone's memory capacity. MemoCase stores text data very effectively and therefore requires small memory area for it. However, if you are storing with MemoCase many images the memory requirements may rise very quickly.

The installation procedure consists usually of following steps:

Install MemoCase ? -> YES

Setting permissions

MemoCase application is developed in Java programming language for the J2ME framwork and therefore it fully takes advantage of its built-in security, restricting in-memory access to its data for other applications. Additionally, the Java/J2ME framework on mobile phones increases security by deploying strict access control to phone's resources for all installed applications. Each time that an application requests access to phone's resources like connectivity, subdevices, memory etc. obtains it only if the phone's user explicitely permits it.

The user's permission may be granted for single access to resource, or may be granted for permanent access. Users permission can be revoked by him anytime.

MemoCase Plus requires for smooth work some permissions:

  • access to phone's local files ( read and edit permissions )

MemoCase Plus can create its data archive backups as files and read the image files, it also can restore the data archive from files

Those permissions can be granted by the Application Manager phone's utility. Please find and select MemoCase in the list of installed applications and open it. Then please set for Multimedia, Read local data and Edit local data either the option Always allowed or Ask first time.
