Android地圖應用程序報告致命錯誤：主要

Question

我正在編輯一個顯示Google地圖中用戶當前位置的Android應用程序。 但是，當我嘗試通過意圖調用活動時，它崩潰並關閉，並顯示錯誤“不幸的是，應用程序已停止”。 我不知道為什么一切似乎都很完美。 但是較舊的應用程序可以正常工作，只是現在已編輯和編譯的應用程序崩潰了。 請幫助我擺脫這個問題。

這是我的Button XML代碼：-

 <Button
        android:id="@+id/button1"
        android:layout_width="180dp"
        android:layout_height="40dp"
        android:layout_marginLeft="80dp"
        android:layout_marginTop="41dp"
        android:background="@drawable/hot"
        android:onClick="MyPlace"
        android:text="MyPlace" />

然后我的Java代碼調用Activity：

public void MyPlace(View v){
    Intent ii= new Intent(Dashboard.this,Myplace.class);
    startActivity(ii);
}

Myplace.java

另外，應用程序是使用某些舊版本的Android Studio創建的，但現在我正在使用Android Studio 3.0對其進行編輯。

Answer 1

我已經通過在項目的build.gradle文件中添加這些依賴關系解決了此問題。

dependencies {  
   compile 'com.google.android.gms:play-services-base:6.5.87'    
   compile 'com.google.android.gms:play-services-maps:6.5.87'  
}
