编程崩溃后重新启动应用程序 - Android电子 [英] Restart App after crash programmatically - Android

问题描述

有没有我对我的应用程序时，它崩溃自动重启本身编程的方法吗？我的应用程序仅仅是一个简单的媒体渲染应用程序，但它偶尔会崩溃（它应该）。这是在所有可能的？谢谢。我的code看起来像这样

 公共无效播放（）{如果（熔点！= NULL）{
             mp.reset（）;
             mp.release（）;
             熔点=无效;
         }
AudioRenderer MR =新AudioRenderer（）;
MP = mr.AudioRenderer（文件路径）;
}私有类AudioRenderer延伸活动{
私人的MediaPlayer AudioRenderer（字符串文件路径）{
文件位置=新的文件（文件路径）;
URI路径= Uri.fromFile（位置）;
MP = MediaPlayer.create（这一点，路径）;
}
回MP
}
 

解决方案

我还是不明白为什么它应该崩溃。

更新

您创建未捕获的异常处理程序的

 私人Thread.UncaughtExceptionHandler onRuntimeError =新Thread.UncaughtExceptionHandler（）{
        公共无效uncaughtException（线程线程，可抛出前）{
            //尝试启动活动再次
    };
 

在上创建，您注册未捕获的异常处理程序的

  @覆盖
    保护无效的onCreate（）{
        super.onCreate（）;
        Thread.setDefaultUncaughtExceptionHandler（onRuntimeError）;
    }
 

Is there a way for my to program my app to automatically restart itself whenever it crashes? My app is just a simple media rendering App, however it occasionally crashes ( it's supposed to ). Is this at all possible? Thanks. My code looks like this

public void Play(){  if(mp != null) {
             mp.reset();
             mp.release();
             mp = null;
         }
AudioRenderer mr = new AudioRenderer(); 
mp = mr.AudioRenderer(filePath);
}

private class AudioRenderer extends Activity {
private MediaPlayer AudioRenderer(String filePath) {    
File location = new File(filePath);
Uri path = Uri.fromFile(location);
mp= MediaPlayer.create(this, path);
}
return mp
}

解决方案

this will do the job for you.

How to start the automatically stopped android service?

still i don't understand why it is supposed to crash.

UPDATE

you create an handler for uncaught exception

    private Thread.UncaughtExceptionHandler onRuntimeError= new Thread.UncaughtExceptionHandler() {
        public void uncaughtException(Thread thread, Throwable ex) {
            //Try starting the Activity again
    };

in your on create, you register an handler for uncaught exception

    @Override
    protected void onCreate() { 
        super.onCreate();
        Thread.setDefaultUncaughtExceptionHandler(onRuntimeError);  
    }
