Google Places autocomplete-Android - funktioniert Nicht

Ich bin neu in Android-App-Entwicklung.
Ich folgte in diesem toturial zu schreiben eine einfache Google Places autocomplete Android-App, aber nicht wieder Anregungen, wenn ich mit der Eingabe beginnen in der app; es gibt NativeCrypto Fehler im LogCat, wenn ich alles schreiben, was in der AutoVervollständigen-textview. Hier ist mein code:

Hier ist mein LogCat Fehler:

• Ich aktiviert haben, Google Places API für Android console.developers.google.com
• Ich bin mit einem Browser Schlüssel für meine app
• Habe ich mich für die Antworten zu meinem problem und habe nicht gefunden eine relevante Antwort noch
• Ich habe Ihnen die Internet-Berechtigungen in der Menifest Datei
• In der Übersicht der Entwickler-Konsole, die Grafik zeigt die Anfragen, was bedeutet, dass Anfragen gemacht werden, aber es gibt keine Antwort.

Jede Hilfe wäre sehr geschätzt werden.
Dank
