Question

我希望用户能够在我的服务崩溃时发送错误报告。我有一个GUI应用程序，它使用来自服务的广播进行更新。该服务在不同的进程中运行并作为前台运行。我使用相同的代码将默认的异常处理程序附加到我的GUI，并在那里工作正常（打开电子邮件发送应用程序和电子邮件的正文包含异常）。但是对于我的服务线程，我无法让它们调用UncaughtExceptionHandler。

我到目前为止所做的研究是，崩溃的线程有一个不同的线程（12），而不是我在（229）上注册了cutom exceptionhandler的线程。注册和崩溃是在同一个Timer_Tick可运行的，应该有相同的线程ID。

Logcat输出：

> D/Registratie: General exception handler set for threadid=229 
> D/Registratie: ThreadName in Timer_Tick: Timer-0 threadId=229
> D/Registratie: ThreadName in Timer_Tick: Timer-0 threadId=229
> D/Registratie: ThreadName in Timer_Tick: Timer-0 threadId=229
> D/Registratie: Throw ArrayIndexOutOfBounds exception W/dalvikvm:
> threadid=12: thread exiting with uncaught exception (group=0x4169fba8)

服务成员和方法：

// declared non-anonymous to prevent the garbage collector erroneously clearing
private Thread.UncaughtExceptionHandler mUEHandler; 


public void attachGeneralExceptionHandler(){

        mUEHandler = new Thread.UncaughtExceptionHandler() {
            @Override
            public void uncaughtException(Thread t, Throwable e) {
                Log.d(TAG, "Custom crash handler: build crashrapport and intent");
                sendExceptionReport(t,e);

                mUEHandler.uncaughtException(t, e);

            }
        };

        Thread.setDefaultUncaughtExceptionHandler(mUEHandler);
        Log.d(TAG, "General exception handler set for ThreadName: " + Thread.currentThread().getName() + " threadid=" + Thread.currentThread().getId());

    }

来自服务的TimerTick：

private Runnable Timer_Tick = new Runnable() {
        public void run() {

            if(!uncaughtExceptionHandlerSet) {
                // Make sure the exception handler is connected to this Timer_Tick thread
                attachGeneralExceptionHandler();
                uncaughtExceptionHandlerSet=true;
            }
            Log.d(TAG, "ThreadName in Timer_Tick: "+ Thread.currentThread().getName()+" threadId="+Thread.currentThread().getId());

            if(testExceptionHandling){
                Log.d("TAG", "Throw ArrayIndexOutOfBounds exception");
                int[] exceptionTest = new int[3];
                exceptionTest[3] = -1; // throws exception on thread with threadid 12, only one line in logcat

            }
}

The program '[2884] WaIISHost.exe: Program Trace' has exited with code 0 (0x0). The program '[2884] WaIISHost.exe' has exited with code 0 (0x0). The program '[12316] w3wp.exe' has exited with code 0 (0x0). The program '[12316] w3wp.exe: Program Trace' has exited with code 0 (0x0).的{{3}}表示：

如果任何线程由于a而死亡，则会调用此处理程序未处理的异常

您不需要为每个线程调用该方法。尝试在服务的Thread.setDefaultUncaughtExceptionHandler()方法中设置默认句柄。

服务默认异常处理程序不起作用（更改了threadID）
