Answer 1

This is more less or less the snippet to share your stuff with other apps except that you specify a specific Component for Picasa. Try this once on a device. Am not sure how it works on emulator.

final int PICASA_INTENT_RESULT = 100;

final Intent picasaIntent = new Intent(Intent.ACTION_SEND); 
picasaIntent.setType("image/*"); 
picasaIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); 
picasaIntent.putExtra(Intent.EXTRA_STREAM, imageUri); 
picasaIntent.setComponent(new ComponentName("com.google.android.apps.uploader", "com.google.android.apps.uploader.picasa.PicasaUploadActivity")); 
startActivityForResult(picasaIntent, PICASA_INTENT_RESULT);

Answer 2

You need to know the package name of Picasa.

Here is a example to launch the browser in Android:

public void doLaunch(View caller) {
    PackageManager packageManager = getPackageManager();
    startActivity(packageManager.getLaunchIntentForPackage("com.android.browser"));
}
