Retrofit error URL query string must not have replace block
From the JavaDoc:
Example 1:
@GET("/friends")
Call<ResponseBody> friends(@Query("page") int page);
Calling with foo.friends(1) yields /friends?page=1. Example with null:
Example 2:
@GET("/friends")
Call<ResponseBody> friends(@Query("group") String group);
Calling with foo.friends(null) yields /friends. Array/Varargs Example:
Example 3:
@GET("/friends")
Call<ResponseBody> friends(@Query("group") String... groups);
Calling with foo.friends("coworker", "bowling") yields /friends?group=coworker&group=bowling. Parameter names and values are URL encoded by default. Specify encoded=true to change this behavior.
Example 4:
@GET("/friends")
Call<ResponseBody> friends(@Query(value="group", encoded=true) String group);
Calling with foo.friends("foo+bar")) yields /friends?group=foo+bar.
URL="/api-mobile_prateek2.php?method=getProductById&pid="
@GET("/api-mobile_prateek2.php?method=getProductById")
Call<Product> responseproduct(@Query("pid") String pid);
dont put the pid in the @GET,, Retrofit automatically fix the url, using @Query
Query params have their own annotation which automatically appends to the URL.
@GET("/users?filters[0][operator]=equals")
UserDto retrieveUsersByFilters(
@Query("filters[0][field]") String nameFilter,
@Query("filters[0][value]") String value);
You can read more about @Query
on its Javadoc
