It does seem beneficial to place file creation and writing on a separate thread. Testing was done on a Motorola Droid and lesser phones adjust performance expectations accordingly when trying on your device. Extensive testing with sufficiently large data sets has not yet been performed. That being said, JExcelApi has handled exporting 5-8 files with 20-40 rows times 4 sheets of data each. This fix is sure to have a performance hit since it must write to device storage. I found that it doesn’t take many files/exports to eat up all available memory on a Motorola Droid. Selenium WebDriver WebDriver is a different tool altogether that has various advantages over Selenium RC. It also allows executing test scripts within the large spectrum of browsers. Just remember to make use of tUseTemporaryFileDuringWrite(true) as mentioned above. Selenium Remote Control (RC) Selenium RC is a server that allows users to create test scripts in the desired programming language. It happily (unlike Apache POI) just works.
Nothing complicated is needed to use JExcelApi in an Android project. To see all of the formatting possibilites JExcelApi offers, consult the documentation downloaded in step 1.

JExcelApi provides all the necessary methods to format your sheets. Note the use of WritableFont and WritableCellFormat to influence the appearance of the cells.
Click on Add External JARs, and navigate to downloaded location where there cucumber related jars are there. Click on Add library and and TestNG and Click Next > Finish.
*/ public WritableWorkbook createWorkbook ( String fileName ) Click on the Build Path > Configure Build Path. In this article, we will discuss about how to read and write an excel file using JExcel API, a simple library and widely used for simple operations which do not involve a high level of formatting and complex formulas based operations. * - a new WritableWorkbook with the given fileName * fileName - the name to give the new workbook file This is no good in a mobile environment so some quick research yielded this fix. It turns out that JExcelApi is a resource hog when creating files. Detailed instructions are beyond the scope of this post. For Eclipse users here is a brief how-to. Add the library to your Android project.Īdd the downloaded.
Navigate to and download the latest release. How do you use JExcelApi in an Android project? I’m glad you asked. This is a minor issue at the moment since all major office suites plan to continue. The lines immediately after the throw is not executed. Perhaps the only disadvantage of JExcelApi is its inability to create the newer. Any statement after throwing an exception: If we add any statements in a try-catch block after throwing an exception, those statements are unreachable because there is an exceptional event and execution jumps to catch block or finally block.
This library turned out to be a great fit for my project since it was much smaller than Apache POI having only bits necessary to create spreadsheet files (as opposed to the full Microsoft Office® suite in Apache POI). Not to be deterred I kept searching for a suitable alternative and was relieved to find JExcelApi. I will gladly provide what little information I have on the task.
Note: If anyone has Apache POI built and working for Android please share your experiences.
I changed it to Label label new Label('A label record') Then while deploying I get a run time excepiton saying :. A few posts here and there hinted that it may be possible to build Apache POI for Android, but I simply do not have the experience building such a massive project for a different platform. Label label new Label(0, 2, 'A label record') It says that the constructor with int,int,str as parameter is not available. You see in order to fit and perform well on mobile devices, Android makes use of a smaller subset of standard Java packages¹. The problem is that Apache POI makes use of several API’s that are not available in Android (StAX, java.awt, others?).
As it turns out, the Apache POI library as downloaded is not compatible with Android and the Dalvik VM. Much to my dismay, Eclipse began throwing build errors stating something like ‘Conversion to Dalvik format failed with error 2’. I proceeded to download the library and import into my existing Android project. Some quick research yielded The Apache POI Project. Unfortunately the app’s exports require formatting so a simple CSV file is out of the question. I need to read large excel files and import their data to my application.A key feature in one of my Android projects is the ability to export the app’s data into a Microsoft Excel® readable spreadsheet.
