Android Studio Room 和 DAO：无法捕获 SQLiteDatabaseCorruptException

编程问答 2022-05-07

问题描述

首先，数据库损坏是故意的，这是对无效的数据库文件上传的测试。 我的问题是异常 (sqliteDatabaseCorruptException) 出现在 DAO 自动生成的 java 代码中：

at com.cormorant.fishingtracker.database.DBDao_Impl$234.compute(DBDao_Impl.java:10024)

所以我无法尝试抓住它！它发生在 AsyncTask 内部，但未捕获异常！我试过了：

protected void openDatabase(OnopenDatabaseResult onopenDatabaseResult) {
        dataRepository.openDatabase(getApplication());
        try {
            dataRepository.getRecordsCount(null,new DataRepository.AsyncResponse<Long>() {
                @Override
                public void processFinish(Long output) {
                    onopenDatabaseResult.onResult(output!=null);
                }
            });
        } catch (Exception exception) {
            exception.printstacktrace();
            onopenDatabaseResult.onResult(false);
        }
    }

也在 AsyncTask 内部：

public class getRecordsCountAsyncTask extends executeOutAsyncTask<Long> {

        getRecordsCountAsyncTask(DBDao dao,Class<? extends Base> klass,AsyncResponse<Long> delegate) {
            super(dao,klass,delegate);
        }

        @Override
        protected Long newDoInBackground() {
            if (mClass== null) {
                Long ret;
                try {
                    ret = mAsyncTaskDao.countTables();
                } catch (Exception exception) {
                    ret =null;
                    exception.printstacktrace();
                }
                return ret;
            } 
...

如何在打开数据库时检测损坏的文件（代码如下）？

    public static Dbroom getDatabase(final Context context) {
        context_ = context;
        if (INSTANCE == null) {
            synchronized (Dbroom.class) {
                INSTANCE = Room.databaseBuilder(context.getApplicationContext(),Dbroom.class,dbFileName)
                        .addMigrations(MIGRATION_1_2,MIGRATION_2_3,MIGRATION_3_4,MIGRATION_4_5)
                        .fallbackToDestructiveMigration() // Wipes and rebuilds instead of migrating if no Migration object.
                        .addCallback(sRoomDatabaseCallback)
                        .build();
            }
        }
        return INSTANCE;
    }
