首先:
如果我有拼写错误,很抱歉。我来自巴拉圭,正在使用谷歌翻译。
这可能看起来有点傻,但我是一个完美主义者,像任何优秀的开发人员和设计师一样,不想在我的项目中出现错误。我正在学习过程中,并希望能从您那里学到更多。
我见过媒体播放器应用程序,允许用户快速并反复按下播放/停止按钮而不会关闭应用程序,并且仍然可以正常运行,因此我阅读了有关服务、异步任务和线程的内容。不仅要在后台播放声音,还要避免UI错误导致应用程序关闭。我还有很多问题。
我想知道是否使用以下资源(在线找到:found online)是正确的方法,但我已经尝试过了,当我多次按下播放/停止按钮时,应用程序会崩溃,有时甚至无法播放歌曲。

我想知道我是否应该随时取消我的 AsyncTask
进程,或者是否应该添加/修改一些内容,以便我的应用程序不会崩溃。我应该如何做?有人能指导我吗?
通常,如果出现错误,我会在日志中看到以下信息:
java.lang.IllegalStateException: Cannot execute task: the task has already been executed (a task can be executed only once)
对于播放/停止按钮:
btn_control.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
control((!ON_PLAY) ? 1 : 0);
}
});
private void control(int est) {
if(est==1){
if (!hayConexion()) {
