当应用程序因未处理的异常而崩溃时显示错误页面

Question

我想在我的应用程序因某些未处理的异常而崩溃时启动 activity。我已经实施了以下内容

public class MyApplication extends Application {

@Override
public void onCreate() {
    super.onCreate();


    Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
        @Override
        public void uncaughtException(Thread t, Throwable e) {
            handelUnCoughtException(t,e);
        }
    });
}


private void handelUnCoughtException(Thread t , Throwable e){
    Toast.makeText(this , "Handeling Error" , Toast.LENGTH_LONG).show();
    Intent serviceintent = new Intent(this , ErrorHandelingService.class);
    startService(serviceintent);
}

}

以上是我的应用程序 class，我在其中设置了默认的 setDefaultUncaughtExceptionHandler 但是我无法在我有代码启动的地方启动我的服务 activity 请帮忙。

我为未捕获的异常写了以下内容class

public class 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);
}

}

并且在我的 activity 中我已经注册了这个 class 所以我可以启动我自己的错误 activity

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