    Alternatives for (Turn Based) Multiplayer

    Posted: 26 Apr 2020 06:11 AM PDT

    Hey fellow android devs!

    Since google has shutdown its multiplayer APIs, I'm looking for a (free) alternative. Currently looking at https://playerio.com/ . Does anyone have some experience or other suggestions?

    Just some context: In my game players have a "preparation" phase where they make some strategic decisions and then a "fighting" phase where they cannot interact but just watch how the fight plays out. Some gameplay can be found here: https://www.youtube.com/watch?v=s05HF9LPITA

    So I guess it would be enough if i send the result of the "preparation" phase and then wait for the other player to respond.

    Any suggestions/feedback is very much appreciated.

    Bluetooth & Tasker

    Posted: 26 Apr 2020 07:58 AM PDT

    I was curious if it would be possible to configure Bluetooth through Tasker to ONLY communicate to MAC addresses I specify...or would this be something achieved by editing a .db or other file somewhere buried on a BT system folder?

    This is related to the Google/Apple tracker fiasco...I'd prefer to disable my phone from pinging other phones and communicating with them.

    The Android ecosystem is new to me, so I apologize in advance if my original question doesn't make sense. Thanks!

    Edit: I'm rooted on Pixel 4 XL, QQ2A.200405.005 and running Kirisakura_Q 4.2.0.

    Creating a music player app

    I can't get my PC to recognize my phone

    Posted: 26 Apr 2020 05:26 AM PDT

    Hey guys!

    So as the topic says I can't get my PC to recognize my phone..

    I have a Xiaomi Redmi Note 4 (Snapdragon) with MIUI 11 Android 7.0

    The problem is that I connect my phone to the PC and nothing happens, doesn't even give me a connect sound and the phone just charges, not giving me any actions to choose from (mtp, ptp, etc). I have USB debugging turned On and still nothing, USB tethering is also grayed out for me. I would love to unlock my bootloader but can't due to this, it doesn't even show up in the device manager at all. I have also never connected my phone to the PC before.

    I have tried: - A billion different drivers, installing, reinstalling, and so. Sometimes I get a code error 10 (donno if it means anything at all) - Restarting my PC and phone a zillion times - I tried manually installing "wpdmtp.inf" (C:\Windows\inf) - Different USB Cables and Ports (USB 2.0 and 3.0) (although all of them work for my brother's Sony phone except for mine) - Disabled Driver Signature Enforcement (I got a warning sign when installing drivers but it seems it did nothing) - Tried multiple PCs (my PC (Win 10) and my dad's PC (Win 7)) - Installed MI suite, MiFlash and such but not even those recognize the phone, it just charged when I connect it to a USB. - I enter Fastboot mode and the phone just automatically restarts itself after like 7-10 seconds - Recovery mode is stable, doesn't restart but I don't have much options to choose (restart into phone, wipe data, connect to MIassistant)

    I am completely lost and trying to figure out WHY it doesn't recognize my phone and only charges. I would appreciate any help and would be grateful for it. Thanks in advanced!

    Question about fragments and activities

    Posted: 26 Apr 2020 05:06 AM PDT

    Hi, I'm in the process of making an Android app for my final year coursework at uni and I've been having trouble using fragments.

    I wanted a navigation drawer and was unsure of how to make one work without using fragments so I've been forced to make every screen of my app a fragment and this has been making my life rather difficult...

    Every tutorial I look at online creates its examples in an Activity rather than a fragment and then when I try to translate the logic over to a fragment things end up not working. Currently I'm trying to get SQLite working within a fragment. I have managed to get it working within an Activity but cannot for the life of me work out how to get it working in a Fragment. I've found having to use fragments a real boundary to me making any progress with many aspects of my app and I don't really know how to get around it. Is there any kind of set of rules for translating code written in an activity to a fragment?

    Also if anyone has any resources specifically about working SQLite inside a fragment it'd be much appreciated because I can't find anything useful online. Thank you for reading.

    Question about scoped storage - music player app

    Posted: 26 Apr 2020 04:30 AM PDT

    Hello friends, hope you're doing well!

    I'm the lead developer of a simple music player app to play music from internal/external memory.

    This morning I received a message on GitHub issues stating that I have to remove the storage permission to make my app compliant with scoped storage and to avoid security issues on API 29 and above.

    I'm not a pro dev and I don't have much devices. I can access to Android 10 only since 1 month. Anyway, some months ago I received bug reports from Android 10 users and made all the necessary changes to make the app compatible (these users luckily tested the changes):

    1. Retrieve media's id and build content uri to play media files and extract other info like birtrate. This change applies to all Android versions supported.

    2. Replace DATA with the new BUCKET_DISPLAY_NAME column to be able to organize music by folder name in Android versions above Android 10.

    3. DATA column is queried only in versions below Android 10 for organizational purpose only, i.e. to be able to organize music by folder name. No reference of full paths is stored into preferences or databases.

    4. Before 1,2,3 changes the quick fix was to opt in legacy storage. I removed it once the users confirmed 1,2,3 changes were working on their devices.

    So, is my app compliant?

    Correct me if I'm wrong, but afaik you can avoid to ask permissions only if you rely on the app's private folder and you try to access files created by the app (I'm actually relying on scoped storage only on another app that saves images to storage).

    If I remove the read storage permission the MediaStore query fails and the app crashes on Android 10.

    I need some pro devs to shed some light. Thanks :)

    Preview of Harmony: A multi-process safe SharedPreference

    Posted: 25 Apr 2020 03:54 PM PDT

    https://github.com/pablobaxter/HarmonyPreferences

    I know there are other "multi-process SharedPreference" libraries out there like Tray (https://github.com/grandcentrix/tray) and Tencent's MMKV (https://github.com/Tencent/MMKV), but what bothered me about them was the use of either NDK or that it used a ContentProvider. I didn't want something to depend on a second process starting, especially if I needed the preference data early.

    Harmony uses no ContentProviders, is available as quickly as SharedPreferences (first read does memory caching), and has no native code (NDK). It implements the SharedPreference interface, and is completely functional. All you have to do to get it is call Harmony.getSharedPreferences(context, "pref_name") in Java or Context.getHarmonyPrefs("pref_name") in Kotlin.

    I'm still actively developing on it (mostly unit and performance tests), so use it at your own risk if you decide to run with it. I know some of us have suffered dealing with multi-process apps and sharing app data between it, so I'm hoping some find this potentially useful.

    Problem with backup and restore permissions via ADB

    Posted: 26 Apr 2020 02:53 AM PDT

    Hello,

    I'm looking for a very quick fix as I'm trying to configure ~400 android 9 tablets!

    I used an MDM solution to do the initial provisioning but I need to configure further using ADB. The devices allow "adb restore" while enrolled (hexnode) but NOT once they are disenrolled, which they all are already now; instead they just don't prompt on screen to restore at all, and time out in ADB.

    Is there an ADB command to enable this permission again? If not I have to factory reset them all and re-enrol them which will take me a long time!

    What are the benefits of Timber?

    Posted: 25 Apr 2020 08:29 AM PDT

    For logging in complex apps (including logging in production) I used Slf4j + Logback combo in the past, wrapped in my own Logger class (or any other name, really). This way I can use many pre-existing encoders, appenders and policies, or write my own (if I have special requirements).

    Nowadays, I see developers use Timber more and more. Undoubtedly, for simple logging requirements (like just limiting logcat to debug builds), Timber is cool. But, as far as I can see, if I'd need to implement any reasonably-complex logging strategy, I'd need to augment Timber with the same Logback (or something similar). So, in essense, Timber would become an additional dependency.

    What benefits do I get from Timber to justify adding it as a dependency?

    My country's security service issued a statement claiming that this app could steal your stuff from your phone including your banking details. How accurate is that?

    In App Billing library - latest

    Posted: 25 Apr 2020 01:46 PM PDT

    I have developed an app which contains some in app purchases. Google has released a new billing library and I cannot find any tutorials on that and neither does google have a java code in its github examples. I have written some code can anyone here help me with it. I have submitted the app in internal track but when opening the page it shows nothing and the logcat too shows no error.
