Hi all,

I updated to the newest version of felgo and now I get a build error that my gradle version doesn’t fit.

I added the androidx in gradle:

implementation "androidx.appcompat:appcompat:1.2.0"

And:

apply plugin: 'com.android.application'

 

But when I compile I get following error:

> Failed to apply plugin [id 'com.android.application']
   > Minimum supported Gradle version is 4.10.1. Current version is 4.6. If using the gradle wrapper, try editing the distributionUrl in C:

How can i update the gradle version, or is there something else I have to do?

Thx,

Patrik

Hi Patrik,

did you follow all steps described in the migration section of the release post:
https://blog.felgo.com/release-3.9.0-overlays-tooltips-news-app-and-webassembly-browser-communication?hs_preview=HSNFSdlu-49421371305#androidx-migration

The required changes include:
– Update gradle version to 3.3.3
classpath ‘com.android.tools.build:gradle:3.3.3’

– Update dependencies to AndroidX
// ADD THIS:
implementation “androidx.appcompat:appcompat:1.2.0”

// REMOVE THIS:
// implementation “com.android.support:support-core-utils:28.0.0”
// implementation “com.android.support:appcompat-v7:28.0.0″

– Change file provider class name in AndroidManifest.xml:
<!– UPDATE android:name HERE: –>
<provider android:name=”androidx.core.content.FileProvider”
android:authorities=”${applicationId}.fileprovider”
android:exported=”false” android:grantUriPermissions=”true”>

– When using Felgo Plugins, add compile option for Java 1.8
android {
// …
compileOptions {
sourceCompatibility 1.8
targetCompatibility 1.8
}
// …
}

Hi Günther,

so far I think I added all those points:

buildscript {
    repositories {
        maven { url 'https://maven.google.com' }
        jcenter()
    }

    dependencies {
    classpath 'com.android.tools.build:gradle:3.3.3'
    }
}

allprojects {
    repositories {
        maven { url 'https://maven.google.com' }
        jcenter()
        maven { url 'https://install.felgo.com/maven/' }
    }
}

apply plugin: 'com.android.application'

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    compile project(':doccheck')
    implementation "androidx.appcompat:appcompat:1.2.0"

    implementation 'net.vplay.plugins:plugin-gcm:3.+'
    implementation 'net.vplay.plugins:plugin-onesignal:3.+'

}

android {
    /*******************************************************

    compileSdkVersion    androidCompileSdkVersion.toInteger()
    buildToolsVersion    androidBuildToolsVersion

    compileOptions {
      sourceCompatibility 1.8
      targetCompatibility 1.8
    }

    defaultConfig {
    multiDexEnabled true
      targetSdkVersion   androidCompileSdkVersion.toInteger()
      applicationId    = productIdentifier
      versionCode      = productVersionCode.toInteger()
      versionName      = productVersionName

      int qtVersionNr = project.hasProperty("qtVersionInt") ? qtVersionInt.toInteger() : 5132
      if (qtVersionNr < 5140) {
        resValue('array', 'load_local_libs', "")
      } else if (qtVersionNr >= 5140) {
        resValue('array', 'bundled_in_lib', "")
        resValue('array', 'bundled_in_assets', "")
      }
    }

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = [qt5AndroidDir + '/src', 'src', 'java']
            aidl.srcDirs = [qt5AndroidDir + '/src', 'src', 'aidl']
            res.srcDirs = [qt5AndroidDir + '/res', 'res']
            resources.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            assets.srcDirs = ['assets']
            jniLibs.srcDirs = ['libs']
       }
    }

    lintOptions {
        abortOnError false
    }
}

And this line I added to my manifest:

        <provider android:name="androidx.core.content.FileProvider" android:authorities="${applicationId}.fileprovider" android:exported="false" android:grantUriPermissions="true">

Thx,

Patrik

Regarding the manifest: There should already be an existing line for the configuration. It only requires an update of the android:name.

A full snippet from e.g. Felgo playground project looks like this:
<!– file provider needed for letting external apps (like camera) write to a file of the app –>
<provider android:name=”androidx.core.content.FileProvider” android:authorities=”${applicationId}.fileprovider” android:exported=”false” android:grantUriPermissions=”true”>
<meta-data android:name=”android.support.FILE_PROVIDER_PATHS” android:resource=”@xml/file_paths”/>
</provider>

You can also try to build & run the Felgo Playground project, to see whether the build works there and to check the default configuration.

Hi Günther,

when I try to compile the playground for v7 release I get the same error. I checked my NDK: android-ndk-r20b. JDK: jdk1.8.0_112.

Thats my whole manifest.

Hi Günther,

ok, I think I missunderstood that Androidx only works with the Android Multi Configuration and the old v7/v8 do not work.

Is this correct?

Thx,

Patrik

[GüntherFelgo Team]

Hi,

are you using the Felgo SDK from our installer with Qt 5.15.2, or did you install Felgo as an extension to a different Qt version via Qt Marketplace?

[GüntherFelgo Team]

Missed you previous reply. Yes, Felgo uses Multi-Configuration for Android builds since Felgo 3.8.0: https://blog.felgo.com/updates/release-3.8.0-call-native-api-qml-javascript-raspberry-pi-qt-5.15.2
The AndroidX requirement apply for the Multi Android-Kit.

Which Felgo version and Android Kit did you use before?

[Patrik Dusek]

Hi Günther,

I was using the previous, latest felgo version. I think it was 3.8.

And in 3.8 the multi plattform wasn’t working.

best,

Patrik

 

[GüntherFelgo Team]

I see, yes you should use the multi-platform Android Kit to be compatible with all latest and future additions.

What error do you have with it?
Can you build with the multi-platform Kit using the default Felgo playground project?
