首次拍照时应用程序崩溃

Question

我是android开发的新手。我们使用flutter开发我们的应用程序。最近我们发现有一个错误。当我们安装该应用程序后，并第一次拍照，该应用程序将崩溃。这是日志

似乎是主要活动重新开始。我认为问题可能出在我之前对kotlin版本进行的修改。在这里

java.lang.RuntimeException: Methods marked with @UiThread must be executed on the main thread. Current thread: DefaultDispatcher-worker-2

是因为这个吗？

Answer 1

基于@HB的建议。我做了以下修改

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    when (requestCode) {
      LOGIN_CODE ->
        if (resultCode == RESULT_OK) {
          if (LoginManager.getInstance().loginService.isLoggedIn) {
            GlobalScope.launch {
              async {
                var ls = LoginManager.getInstance().loginService
                var response = ls.authRequest<AuthResponse<TokenResult>>(AUTH_PROVIDER_NAME)
                return@async response.getToken()
              }.await().let {
                withContext(Dispatchers.Main){
                  methodResult?.success(it)
                  methodResult=null
                }
              }
            }
          }
        } else {
          methodResult?.success("")
          methodResult=null
        }

      LOGOUT_CODE ->
        if (resultCode == RESULT_OK) {
          methodResult?.success(true)
          methodResult=null
        }

      REQUEST_CODE_TAKE_IMAGE_WITH_CAMERA -> {
        if (data != null && resultCode != RESULT_OK) {
          methodResult?.success("")
          methodResult=null
        }
      }

      REQUEST_CODE_CHOOSE_IMAGE_FROM_GALLERY -> {
        if (data != null && resultCode != RESULT_OK) {
          methodResult?.success("")
          methodResult=null
        }
      }

      else -> {
        methodResult?.success("")
        methodResult=null
      }
    }
  }
