android - Dagger2 multi-module design -


for dagger2 release , plan split module few small module re-use on other projects.

application module contains many things, can group 3 type. type related, type b related, type c related.

so want put 3 different module , therefore can re-use part of if need on other projects.

reference google's fork

build.gradle application

buildscript { repositories {     jcenter() } dependencies {     classpath 'com.android.tools.build:gradle:1.1.0'     classpath 'com.neenbedankt.gradle.plugins:android-apt:1.4'      // note: not place application dependencies here; belong     // in individual module build.gradle files     } } allprojects {     repositories {         mavencentral()     } }

build.gradle app module

apply plugin: 'com.neenbedankt.android-apt' //below lines go dependenc compile 'com.google.dagger:dagger:2.0' apt 'com.google.dagger:dagger-compiler:2.0' provided 'org.glassfish:javax.annotation:10.0-b28'

after above steps , going create application module 

@dagger.module public class myapplicationmodule {   void inject(myapplication application); }

and component

@singleton @component(         modules = {typea.class, typeb.class, typec.class}) public interface myapplicationcomponent {

when use on activity , looks 

@component(dependencies = myapplicationcomponent.class,         modules = activitymodule.class) public interface activitycomponent {      void injectactivity(splashscreenactivity activity);

there compile issue

error:(22, 10) error: xxxxxx cannot provided without @provides- or @produces-annotated method. com.myapplication.mxxx [injected field of type: xxx]

i guess there wrong when config activity component extends application component.

my purpose singleton object inside application component , activity inject same object reduce object create every time on activity. design wrong?? or other things need config??

find out root cause come @scope

need expose type other sub-component usage

@scope @retention(retentionpolicy.runtime) public @interface activityscope { }

if want expose context application ,

@singleton @component(          {typea.class, typeb.class, typec.class}) public interface myapplicationcomponent {      void inject(myapplication application);      @forapplication     context appcontext();

when sub-component want extend 

@activityscope @component(dependencies = myapplicationcomponent.class,         modules = activitymodule.class) public interface activitycomponent extends myapplicationcomponent {      void injectactivity(activity activity);

i think great thing dagger2 , let manually expose object need use , code become more traceable.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
