Due to the poor database performance situation on Android operating system, put forward a methods of database access performance optimization. The paper first analyze the Android database access principle, architecture of SQLite and Berkeley DB, and methods of Berkeley DB in concurrent access, then put forward a method of porting Berkeley DB to Android to replace SQLite to enhance the database access performance. Finally a series of practical benchmark results shows that the porting brings performance improvement effect.

Sistem e-farmers merupakan sebuah sistem penjualan berbasis teknologi (e-commerce) yang dapat diakses melalui website, digunakan untuk membantu para petani menjual hasil pertanian berupa beras secara langsung ke konsumen. Namun dengan adanya kendala dalam hal kepemilikan perangkat komputer dan laptop, petani maupun konsumen yang merupakan pengakses website ladangku.id beralih menggunakan perangkat mobile. Dengan alasan ini, maka peneliti membuat sebuah sistem e-farmers yang awalnya berupa website dapat juga diakses melalui perangkat mobile dengan sistem operasi Android. Karena sistem berbasis website berbeda dengan sistem berbasis mobile, untuk itu dibutuhkan sebuah perancangan sistem e-farmer yang berbasis mobile yang akan terintegrasi dengan sistem berbasis website. Di mana metode yang digunakan adalah metode Research and Development (R&D), yang mana mengembangkan sistem yang sudah ada dan hasil akhirnya menghasilkan sebuah produk berupa rancangan sistem aplikasi e-farmers yang dapat berkerja di platform Android.  E-farmers system is a technology-based commerce system (e-commerce) that can be accessed via a website, used for assisting farmers in selling rice product directly to consumers. However, due to the constraint in the ownership of computer and laptop, farmers and consumers as the users of the website ladangku.id now use mobile devices instead. For this reason, the researcher developed an e-farmers system that was initially only accessible via the website but now can be accessed via mobile devices with the Android operating system. Because the website-based system and mobile-based system are different, it is necessary to have a mobile-based e-farmer system design that is integrated with the website-based system. The method used was Research and Development (R&D) method by developing the existing system, and the final product was in the form of a design of e-farmer application system that can work on Android platform.

As android devices have increased in number in the past few years, the android operating system has started dominating the smartphone market. The vast spread of android across all the devices has made security an important issue as the android users continue to grow exponentially. The security of android platform has become the need of the hour in view of increase in the number of malicious apps and thus several studies have emerged to present the detection approaches. In this paper, we review the android components to propose a threat model that illustrates the possible threats that are present in the android. We also present the attack taxonomy to illustrate the possible attacks at various layers of the android architecture. Experiments demonstrating the feature extraction and classification using machine earning algorithms have also been performed.

The android operating system is basically an operating system for mobiles and is rapidly gaining market share, with dozens of smart phones and tablets either released or set to be released. It is mobile operating system that uses a modified version of the Linux kernel 2.6. Google developed Android as part of the Open Handset Alliance, a group of more than 30 mobile and technology companies working to open up the mobile handset environment. Android’s development kit supports many of the standard packages used by Jetty, due to that fact and Jetty’s modularity and lightweight foot print, it was possible to port Jetty to it so that it will be able to run on the Android platform.

Android is an Open Source operating system that gives developers the freedom to develop applications, with the advantages of android operating system, will help many android-based smartphone users to be able to enjoy various applications, one application is the Android-Based Preview Application, the main purpose of this Application is assisting Muslims in reciting the necessary prayers in daily life effectively and efficiently. The type of data used is a secondary data type in which data is obtained from reference books and literature related to this case. There are several stages in making this application, namely analysis, design, work processes, and evaluation of the program model that has been produced. This android-based prayer collection app, can be used on android-based smartphones in the least 4.1 version in this application testing can run smoothly
