Question

尝试从本地db文件（最好是SD卡）加载数据。

在执行任何操作之前，我首先检查是否已安装SD卡。

url: function(params) {
    return '/some/url/' + params.term;
},

这基本上会调用崩溃应用程序的代码部分。

    if (isExternalStorageWritable()) {
        loadFile(SharedPref.getDBPath(this), new DataLoaderCallback() {
            @Override
            public void onDataRetrieved(ImportModel importModel) {

            }
        });
    }

这是错误：

private SQLiteDatabase connect() {
        String dbPath = SharedPref.getManifestPath(mContext);
        File dbfile = new File(dbPath);
        if (dbfile.exists()) {

            return SQLiteDatabase.openDatabase(dbfile.getAbsolutePath(), null, SQLiteDatabase.OPEN_READWRITE);
        }
        return null;
    }

当我使用时：

Failed to open database '/storage/sdcard1/Alarms/data/manifest'.
                                                                    android.database.sqlite.SQLiteException: not an error (code 0): Could not open the database in read/write mode.

                                                                        at android.database.sqlite.SQLiteConnectionPool.openConnectionLocked(SQLiteConnectionPool.java:463)

                                                                        at android.database.sqlite.SQLiteConnectionPool.open(SQLiteConnectionPool.java:177)
                                                                        at android.database.sqlite.SQLiteDatabase.openInner(SQLiteDatabase.java:806)
                                                                        at android.database.sqlite.SQLiteDatabase.open(SQLiteDatabase.java:791)
                                                                        at android.database.sqlite.SQLiteDatabase.openDatabase(SQLiteDatabase.java:694)
                                                                        at android.database.sqlite.SQLiteDatabase.openDatabase(SQLiteDatabase.java:669)

它确实有效，但我只能从文件中读取。我想读写。因此，return SQLiteDatabase.openDatabase(dbfile.getAbsolutePath(), null, SQLiteDatabase.OPEN_READONLY);。该文件具有读写权限，我在清单中添加了此权限。

OPEN_READWRITE

我该如何解决这个问题？
