As in title I need two - client side - AIDL files (service and callback - below) methods to be exposed to B4A.
B4X:
package com.device.n18jsrv;
/// interface to communicate with device
/**
In18Callback.Stub callback = new In18Callback.Stub() {
public void onDisplay(final byte type, final String message) throws RemoteException {
runOnUiThread(new Runnable() {
public void run() {
if (dialog != null)
dialog.dismiss();
if (message != null)
dialog = new AlertDialog.Builder(MainActivity.this)
.setMessage(message)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialogInterface, int i) {
try {
binder.sendOK();
} catch (RemoteException e) {
e.printStackTrace();
}
}
})
.setNegativeButton("C", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialogInterface, int i) {
try {
binder.sendC();
} catch (RemoteException e) {
e.printStackTrace();
}
}
}).show();
}
});
}
};
