Developing new Application

By ptyagi5 on Wed, 06/20/2012 - 17:03
Hi I want to make new application with the help of ImageTargets sample..Iam quiet new to jni and all.....So copied the make file exactly and made the required chages like in mentioning the src files(c/c++) changing the module name,etc...I also copied my project into the sample folder only so that there are no conflicts with the path...I also copied the .externalFolder into my app and made changes copyQCARLib.bat and .sh file to change the application name to my app name instead of ImageTargets...Although I dont know what is the use of this .externalFolder.Please forgive me as Iam a fresher:p..But keen to learn all this... Iam working on windows environment..... The problem is when i do ndk-build of my application,libs folder is created and myapp.so is copied into it but QCARLib.so is not copied.Dont know why... :(.Where as in other samples both .so files are created with ndk build.Also gdbsetup and gdbserver are not created.Dont know their purpose also.... Then if i ignore this and import the project in eclipse following procedure given for other samples and run it...Iam getting exception java.lang.UnSatisfiedError because i guess its not able to load the libraries... I know Iam missing something....But cant figure out...Please help its a bit urgent as i have already spent 3 days in this.....

Hi All, Just passing the Getting Started manual, and come to developing a new application base on ImageTargets. Any article or explanation for the code of this sample? Kind of a tutorial would be great! Still a NEWB. Thanks
