Documentation for Android

[Jorege98]

Hi I'm trying to use the Orianna API on Android Studio, but I can't make it work. I checked the documentation on the website, but it's incomplete

[Jorege98]

This is the problem i get when I try to make a summoner request I/zygote: at java.lang.Object org.cache2k.spi.SingleProviderResolver.resolve(java.lang.Class, java.lang.Class) (SingleProviderResolver.java:110) at java.lang.Object org.cache2k.spi.SingleProviderResolver.resolve(java.lang.Class) (SingleProviderResolver.java:82) at java.lang.Object org.cache2k.spi.SingleProviderResolver.resolveMandatory(java.lang.Class) (SingleProviderResolver.java:64) at void org.cache2k.CacheManager.<clinit>() (CacheManager.java:54) at org.cache2k.CacheManager org.cache2k.CacheManager.getInstance() (CacheManager.java:88) at org.cache2k.configuration.Cache2kConfiguration org.cache2k.Cache2kBuilder.config() (Cache2kBuilder.java:160) at org.cache2k.Cache2kBuilder org.cache2k.Cache2kBuilder.disableStatistics(boolean) (Cache2kBuilder.java:715) at void com.merakianalytics.orianna.datapipeline.InMemoryCache.<init>(com.merakianalytics.orianna.datapipeline.InMemoryCache$Configuration) (InMemoryCache.java:175) I/zygote: at java.lang.Object java.lang.reflect.Constructor.newInstance0(java.lang.Object[]) (Constructor.java:-2) at java.lang.Object java.lang.reflect.Constructor.newInstance(java.lang.Object[]) (Constructor.java:334) at com.merakianalytics.datapipelines.DataPipeline com.merakianalytics.orianna.datapipeline.PipelineConfiguration.toPipeline(com.merakianalytics.orianna.datapipeline.PipelineConfiguration) (PipelineConfiguration.java:178) at com.merakianalytics.datapipelines.DataPipeline com.merakianalytics.orianna.Orianna$Settings$1.get() (Orianna.java:254) at java.lang.Object com.merakianalytics.orianna.Orianna$Settings$1.get() (Orianna.java:251) at java.lang.Object com.google.common.base.Suppliers$MemoizingSupplier.get() (Suppliers.java:120) at com.merakianalytics.datapipelines.DataPipeline com.merakianalytics.orianna.Orianna$Settings.getPipeline() (Orianna.java:247) at com.merakianalytics.orianna.types.core.summoner.Summoner com.merakianalytics.orianna.types.core.summoner.Summoner$Builder.get() (Summoner.java:92)

I discovered topday this is maybe an error produced because of the pipeline, I would like to know how to configure Orianna on android

[robrua]

Hey - sorry for the slow response.

Right now this is an issue with cache2k on android as far as I can tell, detailed here https://github.com/cache2k/cache2k/issues/102. cache2k is the library that underlies the existing in-memory cache in orianna.

It sounds to me like the author intends to help out with this on their end by providing an android-specific build of cache2k that applies the Proguard Rules he specifies to strip out dependencies that aren't available on android.

Until that happens, there are couple of options you have in the meantime:

1) You could apply the Proguard Rules described in section 15.3 of https://cache2k.org/docs/latest/user-guide.html#android in your application. Unfortunately, since cache2k is getting pulled in transitively and isn't part of the ori jar I can't do this myself in orianna.

2) You could configure orianna to not use the in-memory cache for now, which it uses by default (hence your issue creating the pipeline).

If the problem persists in the long-term I'll add an alternative cache implementation for android to fix the issue, but for now I'm patiently hoping the library author gets some time to create an android-specific build of cache2k.

Best, Rob

First of all thanks for your help. I would like to know how to configure Orianna on Android, because I tried to load a JSON and then I get this pipelines and cache2k errors.

[robrua]

If you remove the InMemoryCache section from the default configuration (https://github.com/meraki-analytics/orianna/blob/master/orianna/src/main/resources/com/merakianalytics/orianna/default-orianna-config.json#L7-L158) it should work

[Jorege98]

I make the changes you suggested to me.

First of all, I paste my code: `public class LauncherActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_launcher);

    Orianna.setRiotAPIKey(APY_KEY);
    Orianna.setDefaultRegion(Region.EUROPE_WEST);
    Orianna.loadConfiguration(cargar());

    final Summoner summoner = Summoner.named("OG xPako").withRegion(Region.EUROPE_WEST).get();
    System.out.println("Level: " + summoner.getLevel());

    ConnectivityManager cm =(ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

    NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
    boolean isConnected = activeNetwork != null && activeNetwork.isConnected();

    System.out.println(isConnected);
}

public File cargar(){

    File f = new File(getCacheDir()+"/config.json");
    if (!f.exists()) try {

        InputStream is = getAssets().open("config.json");
        int size = is.available();
        byte[] buffer = new byte[size];
        is.read(buffer);
        is.close();

        FileOutputStream fos = new FileOutputStream(f);
        fos.write(buffer);
        fos.close();
    } catch (Exception e) { throw new RuntimeException(e); }

    return f;
}

}`

This is my config.json file: { "currentVersionExpiration": { "period": 6, "unit": "HOURS" }, "pipeline": { "elements": [ { "className": "com.merakianalytics.orianna.datapipeline.GhostLoader" }, { "className": "com.merakianalytics.orianna.datapipeline.MerakiAnalyticsCDN", "config": { "host": "cdn.merakianalytics.com", "cacheDuration": { "period": 6, "unit": "HOURS" }, "requests": { "connectTimeout": 3, "connectTimeoutUnit": "SECONDS", "rateLimiterTimeout": -1, "rateLimiterTimeoutUnit": "DAYS", "readTimeout": 3, "readTimeoutUnit": "SECONDS", "https": true } }, "configClassName": "com.merakianalytics.orianna.datapipeline.MerakiAnalyticsCDN$Configuration" }, { "className": "com.merakianalytics.orianna.datapipeline.DataDragon", "config": { "cacheDuration": { "period": 6, "unit": "HOURS" }, "requests": { "connectTimeout": 3, "connectTimeoutUnit": "SECONDS", "rateLimiterTimeout": -1, "rateLimiterTimeoutUnit": "DAYS", "readTimeout": 3, "readTimeoutUnit": "SECONDS", "https": true } }, "configClassName": "com.merakianalytics.orianna.datapipeline.DataDragon$Configuration" }, { "className": "com.merakianalytics.orianna.datapipeline.riotapi.RiotAPI", "config": { "http404Strategy": { "type": "RETURN_NULL" }, "http429Strategy": { "backupStrategy": { "backoff": 1, "backoffUnit": "SECONDS", "backupStrategy": { "type": "THROW_EXCEPTION" }, "maxAttempts": 4, "backoffFactor": 2, "type": "EXPONENTIAL_BACKOFF" }, "type": "RETRY_FROM_HEADERS" }, "http500Strategy": { "backoff": 1, "backoffUnit": "SECONDS", "backupStrategy": { "type": "THROW_EXCEPTION" }, "maxAttempts": 4, "backoffFactor": 2, "type": "EXPONENTIAL_BACKOFF" }, "http503Strategy": { "backoff": 1, "backoffUnit": "SECONDS", "backupStrategy": { "type": "THROW_EXCEPTION" }, "maxAttempts": 4, "backoffFactor": 2, "type": "EXPONENTIAL_BACKOFF" }, "httpTimeoutStrategy": { "backoff": 1, "backoffUnit": "SECONDS", "backupStrategy": { "type": "THROW_EXCEPTION" }, "maxAttempts": 4, "backoffFactor": 2, "type": "EXPONENTIAL_BACKOFF" }, "limitingShare": 1.0, "limitingType": "BURST", "rateLimiterTimeoutStrategy": { "type": "THROW_EXCEPTION" }, "requests": { "connectTimeout": 3, "connectTimeoutUnit": "SECONDS", "rateLimiterTimeout": -1, "rateLimiterTimeoutUnit": "DAYS", "readTimeout": 3, "readTimeoutUnit": "SECONDS", "https": true }, "services": [ "com.merakianalytics.orianna.datapipeline.riotapi.ChampionAPI", "com.merakianalytics.orianna.datapipeline.riotapi.ChampionMasteryAPI", "com.merakianalytics.orianna.datapipeline.riotapi.LeagueAPI", "com.merakianalytics.orianna.datapipeline.riotapi.MatchAPI", "com.merakianalytics.orianna.datapipeline.riotapi.SpectatorAPI", "com.merakianalytics.orianna.datapipeline.riotapi.StatusAPI", "com.merakianalytics.orianna.datapipeline.riotapi.SummonerAPI", "com.merakianalytics.orianna.datapipeline.riotapi.ThirdPartyCodeAPI" ] }, "configClassName": "com.merakianalytics.orianna.datapipeline.riotapi.RiotAPI$Configuration" }, { "className": "com.merakianalytics.orianna.datapipeline.ImageDownloader" }], "transformers": [{ "className": "com.merakianalytics.orianna.datapipeline.transformers.dtodata.ChampionMasteryTransformer" }, { "className": "com.merakianalytics.orianna.datapipeline.transformers.dtodata.ChampionTransformer" }, { "className": "com.merakianalytics.orianna.datapipeline.transformers.dtodata.LeagueTransformer" }, { "className": "com.merakianalytics.orianna.datapipeline.transformers.dtodata.MatchTransformer" }, { "className": "com.merakianalytics.orianna.datapipeline.transformers.dtodata.SpectatorTransformer" }, { "className": "com.merakianalytics.orianna.datapipeline.transformers.dtodata.StaticDataTransformer" }, { "className": "com.merakianalytics.orianna.datapipeline.transformers.dtodata.StatusTransformer" }, { "className": "com.merakianalytics.orianna.datapipeline.transformers.dtodata.SummonerTransformer" }, { "className": "com.merakianalytics.orianna.datapipeline.transformers.dtodata.ThirdPartyCodeTransformer" }] } }

And this is what happens when I run the APP:

I'm concerned that the input stream read might not be getting the whole configuration file and that's causing issues - you don't necessarily get the full # of bytes you asked for from InputStream.read.

Can you try replacing your config loading code with:

try(InputStream stream = getAssets().open("config.json")) {
    Orianna.loadConfiguration(ByteSource.wrap(ByteStreams.toByteArray(stream)).asCharSource(Charset.forName("UTF-8")));
}

and see if the same thing happens?

[Jorege98]

Now I get this:

I'm working with API 27 and Java 8 by the way, and trying to load the summoner on main thread

[robrua]

This seems to be an issue with your project configuration rather than anything with orianna specifically. Unfortunately I can't help much with the details of android project configuration since I've never really done it, but here are some observations based on what you've posted:

1) "W/Java7Support: Unable to load JDK7 types (annotations, java.nio.file.Path): no Java7 support added" seems odd to me if you're targeting API 27, as java.nio.file.Path was added to android @ API 26 (https://developer.android.com/reference/java/nio/file/Path.html). Are you maybe targeting a lower API level?

2) Your real problem seems to be that it can't find the Guava classes ori needs though. How are you pulling ori into your project?

[Jorege98]

I'm targeting API 27, here you have my app gradle:

' android { compileSdkVersion 28 defaultConfig { applicationId "com.jerez.summonersgg" minSdkVersion 27 targetSdkVersion 28 versionCode 1 versionName "1.0" testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro' } } }

dependencies { implementation fileTree(dir: 'libs', include: ['*.jar']) implementation 'androidx.appcompat:appcompat:1.0.2' implementation 'androidx.constraintlayout:constraintlayout:1.1.3' testImplementation 'junit:junit:4.12' androidTestImplementation 'androidx.test:runner:1.1.1' androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1' implementation "com.merakianalytics.orianna:orianna-android:4.0.0-rc3" } '

[robrua]

What's the API version of the VM you're using to test the application?

[Jorege98]

it is API 27, Android Oreo 8.1

[Jorege98]

If you want you can see my code in my profile, I'll upload a new commit now

[robrua]

Hey, sorry for the slow turnaround. It looks to me like the Guava transitive dependency from Ori isn't making it into your apk for some reason.

Unfortunately I don't have a dev environment set up for android and I'm not familiar enough with android to figure out why, but some of the most common reasons for that sort of thing are dependency version conflict (e.g a different dependency or android itself is pulling in an older version of Guava that doesn't have the classes Ori is using) and build configurations not including the transitive dependency.

You might try adding a direct dependency on com.google.guava:guava version 20.0 and see what happens. That might help if there's a version conflict.

You could also try asking around on our discord (https://discord.gg/JRDk2JU) to see if any of the android devs there can help you.

[robrua]

We've now upgraded to the latest version of cache2k, which should have fixed this issue.
