Error: Caused by: java.lang.NoSuchFieldError: No static field INSTANCE of type Lorg/apache/http/conn/ssl/AllowAllHostnameVerifier; in class Lorg/apache/http/conn/ssl/AllowAllHostnameVerifier; or its superclasses (declaration of 'org.apache.http.conn.ssl.AllowAllHostnameVerifier' appears in /system/framework/framework.jar:classes3.dex) at org.apache.http.conn.ssl.SSLConnectionSocketFactory.<clinit>(SSLConnectionSocketFactory.java:144) at

推荐答案

org.apache.http.conn.ssl.AllowAllHostnameVerifier

上述类已被删除API级别22

Above class has been removed API level 22

您应该使用改为使用HttpURLConnection 类.
