| Hocus Pocus              | Beer |  4.5 |     812 |             0 | Our take on a classic summer ale.  A toast to weeds, rays, and summer haze.  A light, crisp ale for mowing lawns, hitting lazy fly balls, and communing with nature, Hocus Pocus is offered up as a summer sacrifice to clodless days.Its malty sweetness finishes tart and crisp and is best apprediated with a wedge of orange. |

以上是我的应用程序类，我在其中设置了默认的setDefaultUncaughtExceptionHandler，但在有代码开始活动的地方无法启动我的服务，请帮忙。

Answer 1

我为未捕获的异常编写了以下课程

公共类UncaughtExceptionHandler实现Thread.UncaughtExceptionHandler {

private Context context;
private Class<? extends AppCompatActivity> erroractivity;

public UncaughtExceptionHandler(Context context, Class<? extends AppCompatActivity> erroractivity) {
    this.context = context;
    this.erroractivity = erroractivity;
}

public static void setUpErrorHandlingActivity(Context context, Class<? extends AppCompatActivity> erroractivity) {
    Thread.setDefaultUncaughtExceptionHandler(new UncaughtExceptionHandler(context, erroractivity));
}


@Override
public void uncaughtException(Thread thread, Throwable throwable) {
    new SystemLog().writeAppRecLog("UNCAUGHT_EXCEPTION", "UnCaught Exception.", (Exception) throwable);
    Intent errorActivityIntent = new Intent(context, erroractivity);
    errorActivityIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_CLEAR_TASK);
    errorActivityIntent.setAction("FROM_ERROR_ACTIVITY");
    context.startActivity(errorActivityIntent);
    Process.killProcess(Process.myPid());
    System.exit(10);
}

}

在我的活动中，我已经注册了此类，因此我可以启动自己的错误活动

        UncaughtExceptionHandler.setUpErrorHandlingActivity(getActivityContext(), ErrorActivity.class);

由于未处理的异常导致应用程序崩溃时显示错误页面
