FATAL EXCEPTION：后台任务android.database.sqlite.SQLiteException：没有这样的表。

Posted 2023-01-13

我已经在控制台上加载了apk，测试报告只有1个错误在单一设备上（Galaxy S3，android 4.3）。错误内容如下。

我并没有直接使用SQLite，而只是使用了 SettingsActivity 类，它实现了 AppCompatPreferenceActivity (也许问题取决于这个类)。 我看到过其他类似的主题，但他们总是直接使用SQLite。这里是 SettingsActivity 我正在使用。

public class SettingsActivity extends AppCompatPreferenceActivity 
    private static final String TAG = SettingsActivity.class.getSimpleName();

    @Override
    protected void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

        // load settings fragment
        getFragmentManager().beginTransaction().replace(android.R.id.content, new MainPreferenceFragment()).commit();
    

    public static class MainPreferenceFragment extends PreferenceFragment 
        @Override
        public void onCreate(final Bundle savedInstanceState) 
            super.onCreate(savedInstanceState);
            addPreferencesFromResource(R.xml.pref_main);

            // gallery EditText change listener
            //bindPreferenceSummaryToValue(findPreference(getString(R.string.key_gallery_name)));

            // notification preference change listener
            //bindPreferenceSummaryToValue(findPreference(getString(R.string.key_notifications_new_message_ringtone)));

            // feedback preference click listener
            /*Preference myPref = findPreference(getString(R.string.key_send_feedback));
            myPref.setOnPreferenceClickListener(new Preference.OnPreferenceClickListener() 
                public boolean onPreferenceClick(Preference preference) 
                    sendFeedback(getActivity());
                    return true;
                
            );*/

        if (item.getItemId() == android.R.id.home)

我在网上找到了这个类，它在所有其他设备上都能完美运行。
