Line №44 is mDbxAcctMgr = DbxAccountManager.getInstance(getApplicationContext(), appKey, appSecret);

I don't understand whats wrong?

Thx!


Solution

  • It looks like this is a general issue with native libraries and gradle. I found this SO answer helpful: Include .so library in apk in android studio

    Part of my build.gradle file now looks like this, and my app starts successfully:

    dependencies {
        compile fileTree(dir: "$buildDir/native-libs", include: 'native-libs.jar')
        compile fileTree(dir: 'libs', include: '*.jar')
    }
    
    task nativeLibsToJar(
            type: Zip,
            description: 'create a jar archive of the native libs') {
        destinationDir file("$buildDir/native-libs")
        baseName 'native-libs'
        extension 'jar'
        from fileTree(dir: 'libs', include: '**/*.so')
        into 'lib/'
    }
    
    tasks.withType(Compile) {
        compileTask -> compileTask.dependsOn(nativeLibsToJar)
    }
