using SDK r1
I have a Parcelable I am passing successfully in an AIDL call from a
Service to the Activity that launched the Service, but which jams on
the first parcel.readString() through the same AIDL call to a
different Activity.
Here is my interface's AIDL:
------------
package com.me;
import com.me.MyParcelable;
oneway interface IMyCallbackInterface {
void localInput(in MyParcelable p);
}
---------------
Here are the boilerplate elements of MyParcelable:
------------
private MyParcelable(Parcel in) {
G.debug("read has size " + in.dataSize() + ", avail is " +
in.dataAvail());
mString = in.readString();
G.debug("read string '" + s + "'");
G.debug("read has leftover " + in.dataAvail());
}
public void writeToParcel(Parcel out, int flags) {
G.debug("write string '" + mString + "' into parcel that
already has
" + out.dataSize());
out.writeString(mString);
G.debug("wrote " + out.dataSize());
}
----------------
In the first case, where a Service calls localInput() to the Activity
that launched it, I get the following debug output and sane operation:
12-09 01:11:58.246: INFO/System.out(1054): write string '' into parcel
that already has 100
12-09 01:11:58.256: INFO/System.out(1054): wrote 108
12-09 01:11:58.266: INFO/System.out(1048): read has size 108, avail is
8
12-09 01:11:58.286: INFO/System.out(1048): read sender ''
12-09 01:11:58.286: INFO/System.out(1048): read has leftover 0
In the second case, where the same Service calls the function on an
Activity other than the one that launched it, I get the following
debug output, and the readString() apparently never fires off despite
the fact that there appears to be the same conditions -- 108 bytes of
data, and 8 available before the readString() is called.
12-09 01:16:15.416: INFO/System.out(1054): write string '' into parcel
that already has 100
12-09 01:16:15.416: INFO/System.out(1054): wrote 108
12-09 01:16:15.566: INFO/System.out(1091): read has size 108, avail is
8
---- program seems to wedge here... no further output from my code
results
Obviously, my question is: why is this not working?
I am going to try changing the interface from a oneway to a general
one. I'm stumped, otherwise.
Thanks in advance for any insights.
