Weekly Questions Thread - January 15, 2018

Developing Android Apps - Mon, 01/15/2018 - 05:55

This thread is for simple questions that don't warrant their own thread (although we suggest checking the sidebar, the wiki, or Stack Overflow before posting). Examples of questions:

  • How do I pass data between my Activities?
  • Does anyone have a link to the source for the AOSP messaging app?
  • Is it possible to programmatically change the color of the status bar without targeting API 21?

Important: Downvotes are strongly discouraged in this thread. Sorting by new is strongly encouraged.

Large code snippets don't read well on reddit and take up a lot of space, so please don't paste them in your comments. Consider linking Gists instead.

Have a question about the subreddit or otherwise for /r/androiddev mods? We welcome your mod mail!

Also, please don't link to Play Store pages or ask for feedback on this thread. Save those for the App Feedback threads we host on Saturdays.

Key Intercept on a Pixel 2

Tasker: Total Automation for Android - Mon, 01/15/2018 - 03:45

Hello fellow taskerists!

I've just upgraded my phone to a Pixel 2 (from a Sony) and all my key intercepts have stopped working.

Tasker has admin, battery optimisation is off, accessibilitiy services are on. Does anyone else have this working on a Pixel 2?

Can't import android.widget.* or android.support.v7/4.widget.* in the basic project; why is this? (xpost)

Developing Android Apps - Mon, 01/15/2018 - 00:04

I've tried import android.support.v7.widget.* and android.widget and it won't take either.

I'm really at an impasse as I'm trying to start adding onclick type functionality and get my mind around how this studio works. Any help would be greatly appreciated. It's not my install because if I do the basic activity, import android.support.v7.widget.* are imported and work just fine.

Thanks very much in advance!

Am I understanding leaking context correctly?

Developing Android Apps - Sun, 01/14/2018 - 23:23

My activity makes a network request to fetch data. Once I have it I create my adapter:

subscr = api.getCars(2018, "hatchback") .subscribeOn(Schedulers.io()) .observeOn(AndroidSchedulers.mainThread()) .subscribe(new SimplifiedObserver<List<Car>>() { @Override public void onError(Throwable e) { } @Override public void onNext(List<Car> results) { adapter = new CarAdapter(results); recyclerview.setAdapter(adapter); } });

The observer I define above is inside an activity, and as an anon class instance it holds a reference to the activity. If I rotate the screen, 1 of these happens:

  1. The activity is killed by the time the network request finishes. When the adapter tries to work with views that no longer exist you get a null pointer exception.

  2. Before the null pointer exception occurs the garbage collector sees that the views are still waiting to be updated with a running request so it does not reclaim memory to the heap. Since the activity is being recreated we would not want that old activity and since it is unecessarily taking up memory we have a leak.

Would a solution to both problems be to unsubscribe from the network request like:

@Override public void onPause() { super.onPause(); subscr.unsubscribe(); }

How about if I didn't unsubscribe, would the leak matter? Wouldn't it only be for the duration of the network request?

Thanks.

PSA: In Android 8.0 EditText boxes are all defaulted to "auto" for Google's form autofill.

Developing Android Apps - Sun, 01/14/2018 - 22:49

So if you start seeing weird suggestions that textType won't affect, set isImportantForAutofill to "no".

Use a variable found in Google assistant

Tasker: Total Automation for Android - Sun, 01/14/2018 - 22:20

Hello! I have read through so much involving Tasker and Google assistant, but haven't found any answers for quite what I want to do.

Pixel buds, on a non pixel phone, are a pain to check the battery life. To do this, you have to open Google assistant, tap headphone settings, and then you can see the exact battery %. So, I want to retrieve this battery level for use in a number of ways, I just can't figure out how to access that value with Tasker. Here are images of what the screens look like. screen 1 screen 2. Also, would this value be available without actually opening that screen?

Any help is appreciated!
