dronekit/dronekit-android

@OlavAa

I builded correctly my APP!!! The problem was that I've to include (implementation) all the outer classes of the DroneKit inside my APP gradel!

implementation 'com.jakewharton.timber:timber:4.7.1'
implementation 'com.github.zafarkhaja:java-semver:0.9.0'
implementation 'com.jcraft:jsch:0.1.51'
implementation 'com.googlecode.mp4parser:isoparser:1.1.7'
implementation 'org.droidplanner.android:usb-serial-android:0.1.0'

I don't no why? These classes are included in the ClientLib (DroneKit) Gradel!
I would have imagined that, since they were already imported into DroneKit (ClientLib gradel), in my application I should not have imported them.

Luckely, now my APP works great!

If somebody want to try to develop an APP for Android Oreo+ or more high, has to modify something inside DroneKit:

First, in dronekit project gradel have to change the ext part with this code:

ext {
play_services_version = '8.4.0'

    android_build_sdk_version = 28
    android_build_tools_version = '23.0.2'
    android_build_target_sdk_version = 26
    android_build_min_sdk_version = 22
}

Second, inside AndroidStudioProjects\dronekit-android-v3.0.2\ClientLib\src\main\java\org\droidplanner\services\android\impl\utils\connection
Change the file WifiConnectionHandler.java (line 103) to:
case CONNECTED:
//final WifiInfo wifiInfo = intent.getParcelableExtra(WifiManager.EXTRA_WIFI_INFO);
//final String wifiSSID = wifiInfo.getSSID();
final String wifiSSID = wifiMgr.getConnectionInfo().getSSID();
Timber.i("Connected to " + wifiSSID);

COMPILE (BUILD) DroneKit!

Third, change the project gradel like this:

allprojects {
repositories {
google()
jcenter()

    flatDir{
        dirs 'libs','../../dronekit-android-v3.0.2/ClientLib/build/outputs/aar'
    }
}

}

Fourth, change the compile method in your APP gradel like this (obviously you have to use applicationId, versionCode and versioneNameSuffix of your APP):

compileSdkVersion 29
defaultConfig {
applicationId "com.ttp_technology.ttp_bb_v2"
minSdkVersion 22
targetSdkVersion 26
versionCode 5
versionName "4.1"
testInstrumentationRunner "an29droidx.test.runner.AndroidJUnitRunner"
versionNameSuffix = 'TTP-V4.1'

}
buildTypes {
}
buildToolsVersion = '28.0.3'

Fifth, in your App gradel chenge the implemantation of drone-kit library to:

//implementation 'com.o3dr.android:dronekit-android:3.0.2'
implementation (name:'dronekit-android.3.0.2',ext:'aar')

And now you can cross fingers and built your APP :)

Thank you all for your support.
