私のプロジェクトでAndroid Skype SDK sample codeを使用しようとしていますが、Could not execute method OnClick. SkypeActivity.class cannot be cast to S4BDemoApplication.classというエラーが表示されます。私は私のGradleのあらゆるdexOptionsが含まれていないようMultiDex.install(this)が問題を引き起こしている可能性があります致命的なエラー：クラスを別のクラスにキャストできません。
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
ライン：
私の推測では、私のS4BDemoApplication.classでこのコードの一部です。
私は実際にそれらを持っていたが、私はそれを実行しようとすると、私は
no such property preDexLibraries So I had to comment them out in my gradle and it worked fine.
を言って、エラーを取得するあなたは、これがエラーの原因であると思いますか？このための回避策はありますか？
