Android UncaughtExceptionHandler完成应用程序 [英] Android UncaughtExceptionHandler to finish app

问题描述

我想在记录未处理的异常后关闭应用程序.在这里搜索后，我做了以下事情:

I want to close the app after logging an unhandled exception. After searching here i made the following:

public class MyApplication extends Application {
    //uncaught exceptions
    private Thread.UncaughtExceptionHandler defaultUEH;

    // handler listener
    private Thread.UncaughtExceptionHandler _unCaughtExceptionHandler = new Thread.UncaughtExceptionHandler() {
        @Override
        public void uncaughtException(Thread thread, Throwable ex) {
            ActivityManager am = (ActivityManager)getSystemService(Context.ACTIVITY_SERVICE);
            //logging code
            //..........

            //call the default exception handler
            defaultUEH.uncaughtException(thread, ex);

        }
    };

    public MyApplication() {
        defaultUEH = Thread.getDefaultUncaughtExceptionHandler();
        Thread.setDefaultUncaughtExceptionHandler(_unCaughtExceptionHandler);
    }
}

在呼叫defaultUEH.uncaughtException(thread, ex);之后，我尝试呼叫System.exit()以及android.os.Process.killProcess(android.os.Process.myPid());(甚至我发现有些帖子被告知要同时使用两者).问题是即时通讯出现黑屏，我不得不用电话任务管理器强制退出应用程序.我在做什么错了?

After calling defaultUEH.uncaughtException(thread, ex); i tried to call System.exit() and also android.os.Process.killProcess(android.os.Process.myPid()); (even i found some posts where is told to use both). The problem is that im getting a black screen and i have to force the app exit with the phone task manager. What am i doing wrong?

致谢

推荐答案

最后，我解决了此问题，使该类实现了Thread.UncaughtExceptionHandler接口:

At last i resolved this making a class implementing the Thread.UncaughtExceptionHandler interface:

public class MyUncaughtExceptionHandler implements Thread.UncaughtExceptionHandler {

    private BaseActivity activity;
    private Thread.UncaughtExceptionHandler defaultUEH;

    public MyUncaughtExceptionHandler(BaseActivity activity) {
        this.activity = activity;
        this.defaultUEH = Thread.getDefaultUncaughtExceptionHandler();
    }

    public void setActivity(BaseActivity activity) {
        this.activity = activity;
    }

    @Override
    public void uncaughtException(Thread thread, Throwable ex) {

        //LOGGING CODE
        //........

        defaultUEH.uncaughtException(thread, ex);

    }
}

在BaseActivity中，我添加了以下代码:

In the BaseActivity i added the following code:

//exception handling
private static MyUncaughtExceptionHandler _unCaughtExceptionHandler;

@Override
protected void onCreate(Bundle savedInstance) {
    super.onCreate(savedInstance);

    if(_unCaughtExceptionHandler == null)
        _unCaughtExceptionHandler = new MyUncaughtExceptionHandler(this);
    else
        _unCaughtExceptionHandler.setActivity(this);

    if(Thread.getDefaultUncaughtExceptionHandler() != _unCaughtExceptionHandler)
        Thread.setDefaultUncaughtExceptionHandler(_unCaughtExceptionHandler);
}

我知道它与问题中的代码相同，但是现在可以正常工作了.当我有更多的空闲时间时，我将对此进行深入研究以找到根本原因并将其发布

I know its the same code i have in the question, but somehow its working now. When i have more free time i will look this deeply to find the root cause and post it
