How do I execute a method only after another finish?

I have two method saveLesson() and uploadFile() which takes some time to finish.

I'd like for the second method must start only after the first one finish.

saveLesson();
if (!lessonDetails.get("file").matches(";No file attached")) {
    ArrayList<String> allFileUris = getFileNames(lessonDetails.get("file"));
    uploadFile(allFileUris);
}

This could be one way to suit some needs

boolean firstFunctionResult = firstFunction("1");

Second Function

if (firstFunctionResult) {

    Toast.makeText(mContext,
                   "Dance",
                   Toast.LENGTH_SHORT).show();

    // Can Run Some Function Here

}

First Function

public boolean firstFunction(String variableToCheck) {

    if (variableToCheck=="1") {

        return true;

    } else {

        return false;
    }
}

One is tempted to test a way with OnActivityResult - but one fears it will not be reusable..

you can take below approaches for the same

1) you can call second method from first method itself in the last of first method.

2) You can create a Asynctask and execute first method and after the first method is executed then onPostExecute method call another method
