Question

当我尝试开始任何地图活动时，我遇到了这个崩溃..

这是我的gradle依赖项：依赖{ 编译fileTree（包括：['* .jar']，dir：'libs'） testCompile'junit：junit：4.12'

compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.jakewharton:butterknife:7.0.1'
compile 'com.android.support:design:23.4.0'
compile 'com.facebook.android:facebook-android-sdk:4.5.0'
compile 'de.hdodenhof:circleimageview:2.1.0'
compile 'com.mcxiaoke.volley:library-aar:1.0.0'
compile 'cn.pedant.sweetalert:library:1.3'
compile 'com.squareup.picasso:picasso:2.3.2'
compile 'com.android.support:support-v4:23.4.0'
compile 'com.android.support:multidex:1.0.0'
compile 'com.google.android.gms:play-services-location:8.4.0'
compile 'com.android.support:cardview-v7:23.4.0'
compile 'com.melnykov:floatingactionbutton:1.3.0'
compile 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'
compile 'com.google.code.gson:gson:2.7'

compile 'com.google.android.gms:play-services-maps:8.4.0'
compile 'com.google.android.gms:play-services-gcm:8.4.0'
compile 'com.onesignal:OneSignal:3.4.1'

compile 'com.wang.avi:library:1.0.3'
compile 'com.nineoldandroids:library:2.4.0'


}

这是logcat
