Question

我正在通过finish（）结束活动。

它可以在多个设备上正常运行，但在运行Android 4.4的三星Galaxy S3 Neo上我遇到以下问题：

java.lang.RuntimeException

我找到了两篇关于该主题的帖子：First，Second 但他们没有帮助我。

我的活动代码。请注意，我使用AppIntro：

    public class RegistrationActivity extends AppIntro {

       private AsyncTaskRegisterInBackground registerPushToken;

       (...)

          @Override
            public void onDonePressed() {

               (...)
               if (regid.isEmpty()) {
                                registerPushToken = new AsyncTaskRegisterInBackground();
                                registerPushToken.setParams(activity, gcm, regid);
                                registerPushToken.execute();
                            }
               (...)

            }

    @Override
        public void onTaskCompleted(String responseRegid) {
            try {
                // load authToken from Server: JsonObjectRequest

 builderOnFailureDialog = new MaterialDialog.Builder(activity)
                        .title(getResources().getString(R.string.registrierung_dialog_registrieren_failure_retry_title))
                        .content(onFailureDialogContent)
                        .positiveText(getResources().getString(R.string.registrierung_dialog_registrieren_failure_retry_positive_text))
                        .negativeText(getResources().getString(R.string.registrierung_dialog_registrieren_failure_retry_negative_text))
                        .onNegative(new MaterialDialog.SingleButtonCallback() {
                            @Override
                            public void onClick(@NonNull MaterialDialog dialog, @NonNull DialogAction which) {
                                activity.finish();
                            }
                        }); 

            } catch (JSONException e) {
                e.printStackTrace();
            }
        }

    @Override
    protected void onDestroy() {
        super.onDestroy();

        try {
            onFailureDialog.dismiss();
            onSuccessDialog.dismiss();
        } catch (Exception e) {
            Log.e("Activity.onDestroy()", e.getMessage());
        }
    }

}

或者是后台运行异步任务的问题是什么原因？

Answer 1

在finish()内拨打runOnUiThread()。

即

替换

finish();

带

runOnUiThread(new Runnable() {
                public void run() {
                    finish()

                }
            });

Android：finish（）Activity Runtime Exception
