    Android Cheat Sheet for interviews

    Posted: 28 Jul 2018 06:36 AM PDT

    Where can I find unpaid real work to help build my portfolio/resume and help me learn new skills?

    Posted: 28 Jul 2018 12:29 PM PDT

    Are there any places I can find work like this? I've considered using sites like Freelancer.com and just offering to work at a reduced price as I'm not anywhere near a professional. I learn best when I have a project to work on, so I feel something like this might be best option.

    Encouraging your users to rate your app on the Store, is there a best-practices?

    Posted: 28 Jul 2018 08:32 AM PDT

    It seems users who actually use my app like it, with a strong peak at 5 stars, but I'm getting an annoying amount of drive-by zero stars with reviews like "lol, who needs shit like this". Why somebody would go through the effort of doing that, who knows.

    So, I'm thinking about adding one of those ubiquitous "like this app? Go to the store and rate it" prompts, but was wondering if there is a best-practices. For example, after how many opens should you prompt the first time? If they click "not now", when is the next time? Do you taper it off, i.e. if they keep saying not now, when do you stop bugging them entirely?

    Thanks for any pointers in advance.

    Is there anyway to see a diff in android docs?

    Posted: 28 Jul 2018 10:37 AM PDT

    For example, https://developer.android.com/jetpack/docs/guide shows that "Last updated July 2, 2018."

    Is there any way to see what was actually updated?

    Drop out of college?

    Posted: 28 Jul 2018 09:07 AM PDT

    Hi I just finished my second year of college and am doing an internship at a medium sized company as an android engineer. I am enjoying the work a lot, and if I've learned anything during my time there so far it's that whatever I'm learning at school is not going to help me at all afterwards. So, to save myself 2 years of tuition I'm considering dropping out and looking for a job after my internship and was wondering if it's a good idea or any related advice in general? Thanks!

    Room persistance with ForeignKey fails to insert

    Posted: 28 Jul 2018 07:16 AM PDT

    Hi,

    I'm fairly new to android development and I'm trying to make a project as an exercise to learn room persistence.

    While trying to prepopulate my database I'm getting

    android.database.sqlite.SQLiteConstraintException: FOREIGN KEY constraint failed (code 787)

    I have 2 classes, product and department, each department can have several products (so ForeignKey constraint in product class), they're both very simple classes.

    I can create and insert a department but when I try to insert a product with the department that was just created the app stops/crashes and I get that message as a cause for the stop.

    Here's a pastebin with both classes, their daos and the extension class of RoomDatabase (in which I try to populate) as well as a more complete error message (with a few log lines in front that show how far the populating did go)

    https://pastebin.com/hUwgECzd

    I've tried several hours now to resolve this and now I'm all out of ideas. I either did something stupidly wrong or there's something I simply don't know about that I should do.

    A quick gloss over and tips on where I might look to resolve my mystery misery would be much appreciated.

    I apologize if this is the wrong part of reddit to post this, please just point me to the right location then.

    Querying a Cloud Firestore database with SearchView

    Posted: 28 Jul 2018 06:36 AM PDT

    As the title shows, I want to input text into a searchView (which is in my toolbar) and show the data containing said text in my recyclerview. I've searched all over google, and all the potential answers are for the OLD firebase database, not the newer cloud firestore. Can anybody help me with this, I'm really confused about how i could make this happen.

    Thanks in advance.

    Has anyone else had performance issues with Constraint Layout?

    Posted: 27 Jul 2018 07:22 PM PDT

    I made a keyboard type thing in constraint layout and noticed terrible load times when loading the view. Profiler revealed it was getting stuck in the constraint layout resolver for 4+ seconds. I had to switch to nested linear layouts. I thought constraint layouts were supposed to be more performant than nested layouts?

    There are only 24 elements.

    Quick question: Which API do you use for getting images when searching on a phrase?

    Posted: 28 Jul 2018 03:27 AM PDT

    Building a small app where I want to have an image filled in for the user based on a title they have given.

    Ofcourse i'm searching for a Free API because this is just a hobby project :) I googled around and have seen a few:

    https://developer.gettyimages.com/docs

    Google's Image API is gone

    any more, or which do you prefer?

    Package a VPN into my app

    Posted: 28 Jul 2018 05:58 AM PDT

    I am building a streaming as a service application but my ISP is being infuriatingly difficult in opening ports for my server. I am looking into alternatives such as packaging a vpn directly into the app.

    Is this possible? I have looked into ZeroTier One and while the prebuilt packages work, I can't get the libraryversion up and running. Any other alternatives or solutions?

    How to layout views in constraint layout programmatically

    Posted: 27 Jul 2018 05:16 PM PDT

    Im trying to add a linear layout programtically thats width is calculated by a constraint vertical guideline. But nothing is added to the layout. I know that I need to add my views first and clone the whole layout and then start linking each element but I dont even think my guideline is being created. How can I debug this?

    // ID for linearlayout thats used with the constraint layout int id = 100; LinearLayout linearLayoutTime = new LinearLayout(context); linearLayoutTime.setBackgroundColor(getResources().getColor(R.color.colorPrimary)); linearLayoutTime.setId(id); linearLayoutTime.setOrientation(LinearLayout.VERTICAL); linearLayoutTime.setLayoutParams(new Constraints.LayoutParams(LayoutParams.MATCH_CONSTRAINT, LayoutParams.MATCH_CONSTRAINT)); ConstraintSet set = new ConstraintSet(); // add some views to the linear layout for (int h = 0; h < hours; h++) { // textview tv.setText(tvTime); linearLayoutTime.addView(tv); } // add linear layout to main view addView(linearLayoutTime); //clone the whole view set.clone(this); int guideLineID = 101; set.create(guideLineID, ConstraintSet.VERTICAL_GUIDELINE); set.setGuidelinePercent(guideLineID, 0.5f); // connect the linear layout so that the left of it connects to the left of the constraintlayout and //the right to the guideline just created. Top and bottom of th elayout connect to the respective //locations of the constrAINT LAYOUT. set.connect(100, ConstraintSet.LEFT, this.getId(), ConstraintSet.LEFT, 0); set.connect(100, ConstraintSet.RIGHT, guideLineID, ConstraintSet.RIGHT, 0); set.connect(100, ConstraintSet.BOTTOM, this.getId(), ConstraintSet.BOTTOM, 0); set.connect(100, ConstraintSet.TOP, this.getId(), ConstraintSet.TOP, 0); set.applyTo(this);

    Using Code from Github

    Posted: 28 Jul 2018 07:53 AM PDT

    Fellas I am a novice developer who has the basic knowledge and was taking a first shot at app development , so I had an app idea which used maps sdk for it's core features , while searching for some examples on GitHub , I found a project which had the same core features , so I thought I'd use the code while adding some more extra features to it , So I thought is this the right way or am I being too lazy of a developer + I don't want to hurt the original owners of the project of which I am using the code , help me with this guilt and anxiety

    And sorry for my bad English :)

    Firebase Question : How do you save long posts submitted by multiple users? Do you use child node or file storage?

    Posted: 28 Jul 2018 07:12 AM PDT

    Basically, I have an app in which users can submit their articles (5000 characters) and then others users can see these articles.

    Do you use a child node to save it or do you use file storage? If use file storage can you provide any tutorials which you have found useful.

    Thank you! :)

    I've been reading a lot about the android jetpack stuff and would like to try and learn as much of it as I can, I've downloaded android studio 3.3 but feel slightly overwhelmed not knowing where to begin.
