I know this issue has reported by other developer，but don`t get a good answer。There are some clue :

• all crash happened at background
• at crash time , has Network ,has the net permission，but can’t do net operation。
• when crash happened,I can catch the crash, when call Call.execute() ,but can’t catch when call Call.enqueue() I suggest that, at asynchronous call mode(Call.enqueue()) , to callback Callback.onFailure when this exception happend。

My English is poor , may be don’t describe clear.

I think you can write a Application Interceptor to catch java.lang.Throwable or java.lang.RuntimeException that you want. Wrapping the exception as a IOException and throw out, your Callback#onFailure method will be invoked. You can also get the wrapped exception in the method parameter.

I put the code here, may be help other one.

    public static OkHttpClient getHttpClient() {
        if (httpClient == null) {
            synchronized (TvBase.class) {
                if (httpClient == null) {
                    OkHttpClient.Builder builder = new OkHttpClient.Builder();
                    builder.addInterceptor(new OkHttpExceptionInterceptor());
                    builder.connectTimeout(30, TimeUnit.SECONDS);
                    builder.writeTimeout(30, TimeUnit.SECONDS);
                    builder.readTimeout(30, TimeUnit.SECONDS);
                    httpClient = builder.build();
                    httpClient.dispatcher().setMaxRequestsPerHost(30);
                }
            }
        }
        return httpClient;
    }

    /** okhttp AsyncCall only catch the IOException, other exception will occur crash，this Interceptor impl can transform all exception to IOException */
    private static class OkHttpExceptionInterceptor implements Interceptor {

        @Override
        public Response intercept(Chain chain) throws IOException {
            try {
                return chain.proceed(chain.request());
            } catch (Throwable e) {
                if (e instanceof IOException) {
                    throw e;
                } else {
                    throw new IOException(e);
                }
            }
        }
    }
