#AsyncTaskScheduler ##Background ????AsyncTask???????????? ##Characters
- execute tasks in parallel as default, rather than processing them sequentially
- execute single task use a thread rather than an executor
- you can set a default executor to execute tasks
- a callback for task error
- manage multiple tasks easily
- you can you it on any thread ,anf it will have a callback on main thread?
##Methods Introduction methods like AsyncTask ,use easily
- doInBackground : background thread
- onProgressUpdate : main thread
- onExecuteSucceed : main thread
- onExecuteCancelled : main thread
- onExecuteFailed : main thread,when unexpected happened
##Add to project latest-version:
Step 1. Add the JitPack repository to your build file
gradle
allprojects {
repositories {
...
maven {
url "https://jitpack.io"
}
}
}
maven
<repositories>
<repository>
<id>jitpack.io</id>
<url>https://jitpack.io</url>
</repository> </repositories>Step 2. Add the dependency
gradle
compile 'com.github.SilenceDut:AsyncTaskScheduler:{
latest-version
}
'maven
<dependency>
<groupId>com.github.SilenceDut</groupId>
<artifactId>AsyncTaskScheduler</artifactId>
<version>{
latest-version
}
</version> </dependency>##How to use Single background task ,use a single thread rather than an Executor, save resource
SingleAsyncTask singleTask = new SingleAsyncTask<Void,String>() {
@Override
public String doInBackground() {
return null;
}
@Override
public void onExecuteSucceed(String result) {
super.onExecuteSucceed(result);
}
@Override
public void onExecuteFailed(Exception exception) {
super.onExecuteFailed(exception);
Log.i(TAG,"onExecuteCancelled:"+exception.getMessage()+Thread.currentThread());
}
}
; singleTask.executeSingle();
//????executeSingle????? mSingleAsyncTask.cancel(true);
multiple background tasks,create a task scheduler to manage them.
//????????????? AsyncTaskScheduler mAsyncTaskScheduler = new AsyncTaskScheduler();
SingleAsyncTask singleTask1 = new SingleTask() {
...
}
? SingleAsyncTask singleTask2 = new SingleTask() {
...
}
? SingleAsyncTask singleTask3 = new SingleTask() {
...
}
? ... //???????? mAsyncTaskScheduler.execute(singleTask1) .execute(singleTask2).execute(singleTask3).
//????AsyncTaskScheduler?? mAsyncTaskScheduler.cancelAllTasks(true);
you can set a default Executor to execute tasks
//???????? Executor defaultPoolExecutor = ... AsyncTaskScheduler mAsyncTaskScheduler = new AsyncTaskScheduler(Executor defaultPoolExecutor);
make sure cancel task to avoid memory leak
//????executeSingle????? mSingleAsyncTask.cancel(true);
//????AsyncTaskScheduler?? mAsyncTaskScheduler.cancelAllTasks(true);
