起因
基类 主要提供和原生application一样的方法
public abstract class BaseMovieApplication {
private Application application;
public BaseMovieApplication(Application application) {
this.application = application;
}
public Context getApplicationContext() {
return this.application.getApplicationContext();
}
public Context getContext() {
return this.application.getApplicationContext();
}
public Application getApplication() { return this.application;
}
public abstract void onCreate();
public void onConfigurationChanged(Configuration newConfig) {
}
public void onTerminate() {
}
public void onTrimMemory(int level) {
}
}
主进程
/** *

* Project:aimovie
* Detail:主进程实例 也就是ui进程
*/
public class MovieMainProcessApplication extends BaseMovieApplication {
public MovieMainProcessApplication(Application application) {
super(application);
}
@Override
public void onCreate() {
//执行主进程所需要的方法
//eg 初始化图片库
// crash 平台等
}
}
如果要调用application的方法直接调用getApplication()然后再调用你需要的方法即可
getApplication().registerActivityLifecycleCallbacks(new ShowDialogActivityLifecycleCallback());
其他进程一样只要继承BaseMovieApplication即可
Application拆分
public class MovieApplication extends MultiDexApplication {
private static Context sContext;
private BaseMovieApplication baseMovieApplication;
/**
* 返回当前MovieApplication
*/
public static Context getContext() {
return MovieApplication.sContext;
}
@Override
public void onCreate() {
super.onCreate();
MovieApplication.sContext = getApplicationContext();
if (MtmpManager.isMainProcess(this)) {
baseMovieApplication = new MovieMainProcessApplication(this);
} else {
baseMovieApplication = new MovieSecondProcessApplication(this);
}
baseMovieApplication.onCreate();
}
@Override
public void onTrimMemory(int level) {
super.onTrimMemory(level);
if (baseMovieApplication != null) {
baseMovieApplication.onTrimMemory(level);
}
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
if (baseMovieApplication != null) {
baseMovieApplication.onConfigurationChanged(newConfig);
}
}
@Override
public void onTerminate() {
super.onTerminate();
if (baseMovieApplication != null) {
baseMovieApplication.onTerminate();
}
}
}
也可以根据进程名进行更多进程的拆分,每个进程实例做对应的初始化操作。这样结构就很清楚了~每个进程执行每个进程的操作,初始化,也不会一个对象因为多个进程,初始化多个。也不需要再担心一个方法会影响别的进程。。。
拆分的好处:
1.避免oncreate等方法调用多次引起的bug
2.减少资源浪费 在一些push进程 可以不初始化 图片库等
3.各尽其职
4.再也不用经常去判断进程
