Can't open Android Native Demos

Hi, I'm very new to Android Studio and I'm having trouble opening the demos provided in the Android Realtime SDK.

The readme doesn't say what environment these were build in, so I'm assuming it was they work in Android Studio.

I open a project and select the root folder of the project, for example:
/Photon-AndroidNDK-Sdk_v4-1-16-3/Demos/demo_loadBalancing
where the run button normally is there's an option to configure when I configure it as an app and try to run it says it's missing the AndroidManifest.xml

When I load the folder that has the AndroidManifest it says it's missing a module.

I'm also having trouble loading the library into a new project. I can link the C++ library to it, but I then have troubles writing a NetworkLogic controller, or calling the code from Java, but I figure this isn't the place for that so I'm mostly concerned with loading the demo projects and messing around with them

  • Hi @ImMilesAhead.

    The demo projects ship with makefiles for NDK-build and with VisualGDB projects.
    Android Studio is not necessary to build and run the demo projects. You can either use Visual Studio with VisualGDB or run the plain makefiles directly from the command line.

    You can create Android Studio projects for the demos buy following the guides at https://developer.android.com/studio/projects/add-native-code.

    See https://developer.android.com/studio/projects/gradle-external-native-builds for how to add native libraries like the Photon Android libraries to your project.

    Note that wherever those guides differentiate between cmake and NDK-build, you should go with the NDK-build instructions.

    Thanks @Daguo that link has gotten me almost all the way but I can't get the ndk-build to run properly.

    I'm trying to build the library using ndk-build but I get an error:
    C:\Users\Miles\AppData\Local\Android\Sdk\ndk\21.3.6528147\build\ndk-build.cmd

    Process finished with exit code 2
    

    I've checked and double checked the paths and all the Android.mk files, but I can't get it to compile

    I've even copied and pasted the file path from the terminal and it goes to the correct directory, so I don't think I'm insane.
  • Hi @ImMilesAhead:

    This looks like a path-length issue. Due to the way how ndk-build works it can happen on Windows that you cross the maximum limit length limit of Windows when you include 3rd party libs in Android projects that are located at relatively long directory paths.

    Try moving your project to a shorter path.

    For a quick check if this is indeed the cause of the problem, you can simply copy your project folder to a location like C:/a.
  • so it seems it was a path issue, as I was able to get the .so files compiled.

    Now however I can't access any of the native functions from within Java. I copied from DemoActivity.java and it crashes on startup. idk if I need to import anything, but I tried leaving the activity blank and was able to runt he app with the compiled c++ code not doing anything. I try to call startDemo(); in onCreate(Bundle savedInstanceState) and the app crashes.
  • Hi @ImMilesAhead

    you can show the error info printed in logcat window.

  • Hi , @ImMilesAhead
    E/h.clutchbowlin: No implementation found for void com.cerebralclutch.clutchbowling.MainActivity.startDemo() (tried Java_com_cerebralclutch_clutchbowling_MainActivity_startDemo and Java_com_cerebralclutch_clutchbowling_MainActivity_startDemo__)
    

    1.Your package name is "com.cerebralclutch.clutchbowling".
    2.You can check the code is found "Java_com_cerebralclutch_clutchbowling_MainActivity_startDemo" in main.cpp.
    3. You should replace "demo.android.loadBalancing" by "com.cerebralclutch.clutchbowling".replace "DemoActivity" by "MainActivity" .
  • I have just one last error, I finally got everything working so long as the package name is demo_android_loadBalancing
    if it's anything other than this I get a connection error 1023

    specifically the app loads logs
    connecting to Photon
    received connection error 1023
    disconnected
    
    I changed the function names in main.cpp like @Daguo said and the app compiles and runs fine except for this error.
    Nothing shows up in Logcat, but in the Run tab I get
    E/Photon-Demo: 2020-09-14 15:58:11,131649 ERROR   PeerBase.cpp                   onConnect()                                                  422   4294967295

  • actually that shows up in logcat too, I didn't change what package it was monitoring
  • Running the command with -d flag gives me this

  • Hi @ImMilesAhead.

    As you can see in the link that @Daguo has provided, the connection issue might simply come from a missing Internet-permission in the manifest file. Have you checked that?

    What is the context of your last post?
    It looks like you are back to the path length issue.
  • uh... idk why that posted now. I posted that a week ago. I got a message that it would post when it was approved or something. Probably because it's so long. but yeah that was back with the path length issue
  • also i've got the permissions, and I can connect when the package name is demo.android.loadBalancing, but not when I change the package name. I've tried both starting with a different package name and changing it after the project is created.

    I've made sure to change all refrences in the main.cpp (otherwise it would crash)


    also just to make sure I just paste
    <permission-group android:name="android.permission-group.NETWORK" />
        <uses-permission android:name="android.permission.INTERNET" />
    
    into the root of the AndroidManifest.xml

    it looks like this now
    <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.cerebralclutch.clutchbowling">
        <permission-group android:name="android.permission-group.NETWORK" />
        <uses-permission android:name="android.permission.INTERNET" />
    
        <application
            android:allowBackup="true"
            android:icon="@mipmap/ic_launcher"
            android:label="@string/app_name"
            android:roundIcon="@mipmap/ic_launcher_round"
            android:supportsRtl="true"
            android:theme="@style/AppTheme">
            <activity android:name=".MainActivity">
                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />
    
                    <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>
            </activity>
        </application>
    
    </manifest>
    
  • it looks like it's just com.cerebralclutch.clutchbowling that I can't connect. If I set it to something different like com.clutch.bowling it works fine.
  • Hi @ImMilesAhead.

    Google restricts the max length for the package name to 30 characters (apparently 50 characters if you only want to support very recent Android versions and set the API version accordingly high, but I have not tested this).
    "com.cerebralclutch.clutchbowling" is 32 characters long a hence 2 characters beyond that limit.
    Shortening it by 2 or more characters should do the trick.
    uh... idk why that posted now. I posted that a week ago. I got a message that it would post when it was approved or something. Probably because it's so long. but yeah that was back with the path length issue
    Ah, OK. Likely an automated algorithm of the forum software put in the SPAM-queue and a colleague has manually approved it after verifying that it wasn't spam. Thanks for clearing that up. I thought you wrote this post today and was confused because I thought that we were past that issue.
