I have uploaded a new alpha of CogDroid:

Intent filtering has been added to the application. Also application icon and Java package name (org.golubovsky.cogstack) have been updated.
Intents in Android are messages that an application may pass around to invoke other applications that subscribe to filtering intents with some properties.
That is, another application may broadcast an Intent (via startActivity()) with scheme "file", content-type "application/x-squeak-image", and path to the image as data. CogDroid will start right with the image given (provided that it exists) without scanning the sdcard storage for available image files.
Sample Java code for this:
public void launchImage(String imgpath) { Intent cog = new Intent(); cog.setAction(Intent.ACTION_VIEW); Uri uri = new Uri.Builder().scheme("file").path(imgpath).build(); cog.setDataAndType(uri, "application/x-squeak-image"); try { startActivity(cog); } catch (Exception e) { // process the exception: it is raised if no recipients were found for this intent, e. g. CogDroid is not installed. } }
Relevant section in CogDroid's AndroidManifest.xml:
<intent-filter> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> <data android:scheme="file" android:mimeType="application/x-squeak-image" /> </intent-filter>
I also created a simple launcher for two images (the application when installed shows an icon for each image). Unfortunately image paths are hardcoded (but just for illustration this should be OK), and a single Activity subclass is required for each image file.

Thanks.
