If you have resources that change like XML config files, it's better to generate them from the code since uploading them to the phone will overwrite the configuration. Naming of resources is really restrictive in Android, for example you cannot have several resources with the same name even if they have different extensions. The AndroidDebug target does a different compilation process of the native code that allows it to detect linker errors that won't be detected when compiling in AndroidRelease mode.
It is recommended to compile your application in AndroidDebug mode at least once or if your application crashes before starting. When installing applications on the device or emulator it is recommended to use the AndroidRelease mode since it's faster and the applications will be much smaller. Test your application very often. Even if the last NDK allows for debugging, there's no support for native debugging in Eclipse and setting it up manually with the NDK is pretty hard.
When an application crashes the debugger dies too, so it's hard to debug bad memory accesses and similar bugs. Use the LogCat view in Eclipse. When programming for Android you cannot see the output of cout or printf, but if you use ofLog you can see its output in the LogCat.
Learn how to create applications in an Android development environment in this guide.
You can see the output of the compiler in the Console tab and the output of your app in the LogCat one. Everything that is output by openFrameworks through ofLog will have an openFrameworks tag so you can use filters to see only your application's output.
Open Eclipse and tell it to use this new folder as a workspace.
Do the import steps again for the new folder, including openFrameworks, libs, addons but instead of importing all the examples, import only androidEmptyExample to have a template for your new projects. You can copy any of the examples and start a new application from there. It's currently far more difficult to create a project from scratch, since the makefiles and project settings contain a lot of details you would need to duplicate.
In Eclipse this is easily done by right-clicking on an existing project, selecting Copy, then right-clicking on the workspace and selecting Paste. A small Copy Project window will pop up for you to pick a new project name and location. For now, project name and directory must have the same name. Let's say your application is called myApp, this must also be the name of your folder. It's important to keep the package prefix as cc. This will be fixed in future versions when Eclipse support for native code is better.
Check the libs folder. It should be populated with a library during the build. On Linux it is a file that ends with.
Set up the Eclipse project and build the Android app
You may also see something like this in your LogCat:. The device must have an SD card if you use resources in your openFrameworks app. Note that some devices have an internal SD card, like the Galaxy Tab Donations help support the development of openFrameworks, improve the documentation and pay for third party services needed for the project.
If you are using openFrameworks commercially or would simply like to support openFrameworks development, please consider donating to the project. Note : see the FAQ at the bottom of this page if you're having trouble. Setup the Android Eclipse plugin. Download openFrameworks either from the download page, or clone from git. Import the openFrameworks projects into Eclipse. Compile and install one of the Android openFrameworks examples to confirm that everything works. For Linux, it will probably be in the official repositories. For example, in Ubuntu: sudo apt-get install openjdkjdk or sudo apt-get install oracle-java8-installer b Android SDK : This is the software that allows you to write Android apps.
Enter the correct paths for your system and save this file as paths. Click 'Add Now Eclipse knows where the SDK is. Do the same for the path to the NDK. Check that it is being detected and restart adb server if necessary. If everything went OK, the example should start on the device. If you have resources that change like XML config files, it's better to generate them from the code since uploading them to the phone will overwrite the configuration If there's no SD card in the device, examples that have resources won't work right now.
The following lines present the contact times, the altitude and azimuth angle of the event. The position angle to celestial north is given also, as well as the position angle to local zenith, given in an o'clock value. If C1 has an o'clock position of 3, this means, that the moon will start the eclipse by touching the solar limb exactly from the right side. This feature can be deselected via the settings menu in the main screen. You can also select to show a NASA map of the eclipse in your web browser.
EclipseDroid stores and applies internally the offset as a correction parameter. In this screen you can select the offset i.
However, my desire has an average delay of about 1 second. It seems to be quite precise. If you do not have a network connection, you can force a continuous synchronization of EclipseDroid's time to GPS time. A central item of EclipseDroid is the ability to use scripts, launching user defined actions depending on the actual contact times of your location.
To show user defined events, announcements or to take snapshots automatically you must select the "actions file" in the settings menu. This is a kind of CSV file with data rows and semicolon separated columns. For special actions like DSLR photos there may follow optional parameter rows. Once you have selected the file, you can edit it either using your favourite Computer or Android text editor or using EclipseDroid's simple text editor in the menu.
The file will look similar like this below. It is just an example how to access audio files. Do not finish the emergency script with a long time exposure, as the regular list will be loaded after execution!

- Media, War and Postmodernity;
Each line consists of a minimum of four rows, separated by a semicolon. The meaning of those entries are: First row: The contact.
To enter times relative to the proceeding command, you can use the P letter. P;2; indicates two seconds after the last one. There is also the possibility to select absolute times, indicated by the letter "A".
Migrating from Eclipse
A-times are UTC, not local time!! For the emergency list or logging entries you may choose the letter "E" like Emergency. These times are counted and logged from the moment when the list has been loaded. Second row: The time. Do not enter local time zones! Third row: The action. Actions can be: SHOW displaying a text on the main screen in classic layout. As the actions list will only be displayed in the classic menu, I recommend setting EclipseDroid in to classic layout just before your eclipse observation. Go to the preferences and select "Classic layout" LOG will write a text into the EclipseDroid log file, for example indicating certain phases of your observation program or to protocol loading a script.
You can specify a desired language by adding a language code parameter. The selected language is kept until the next change. PHOTO , taking a snapshot with the internal camera. For a documentation of the infrared setup details see my documentation for CameraTimer.

Download sample ircommands. Click here to obtain commands for the Sony Alpha 7 camera and perhaps other Sonys and save it as. Thanks to Brad Templeton! FLASH , to release the camera flash, e. The following number is the flash duration in ms, try something in the range from to ms. My EOS D accepts ms. You will find a description of an optical interface cable to use the flash light of your phone for releasing a camera in my description of the Android App CameraTimer.
It searches first for the application label case sensitive , then makes case insensitive search, if not found yet it searches for class name sub string, case insensitive. It switches to LifeView mode, though does not display an image. But this works like the mirror lockup avoiding camera shake by the mirror. See tips below for usage. Useful to avoid that a late launched totality emergency script extends into Baily's beads phase. For internal photos you can select a file for storage. If nothing selected, the file name will be "EclipseDroid".
The date and time will be added in every case. Chose the desired photo directory in the settings menu of the main screen!
