BITTE HELFEN SIE MIR...WAS IST DAS PROBLEM ?

  • Der Fehler ist klar: Ab der zweiten Zeile: "AdView kann nicht gewirkt werden, um android.- widget.LinearLayout", und etwas weiter unten (Zeile 15): "Caused by: java.lang.Classcastexception-Fehler: com.google.android.gms.anzeigen.AdView kann nicht gewirkt werden, um android.- widget.LinearLayout an com.Beispiel.gamecik.MainActivity.onCreate(MainActivity.java:32)". Also sehen Sie in Zeile #32 in deiner Quelle, wo du bist typecasting AdView als LinearLayout. Sie können nicht, wie die Fehlermeldung klar sagt. Lesen Sie die Worte, die in der Fehlermeldung - Sie oft tatsächlich einen Sinn haben.
  • bitte posten Sie Ihre XML
