RxJava how to observe on mainThread in older versions? I dont have access to AndroidSchedulers.mainThread()

Im building a project using web3. 

web3j.ethGetBalance("0x2910543af39aba0cd09dbb2d50200b3e800a63d2", latestBlock)
            .observable()
            .subscribeOn(rx.schedulers.Schedulers.io())
            //This needs to be on the main thread!
            //But i only have access to rx.schedulers not AndroidSchedulers.mainThread()
            .observeOn(rx.schedulers.Schedulers.io())
            .subscribe(block -> {
                ethereumTV.setText(block.getBalance() + "");
            }, error -> {
                error.printStackTrace();
            });

But web3 uses an older version of RxJava and i cant access the mainThread to observe on it (To update text views etc)

Any ideas?

Solution 
  • compile 'io.reactivex:rxandroid:1.2.1' // <-- this is needed
compile 'io.reactivex:rxjava:1.1.6'

    Then you can get

    in 'rx.Observable' cannot be applied to '(io.reactivex.Scheduler)'

    In which case do

    rx.android.AndroidSchedulers.mainThread()
