Saya yakin bahwa masalah Anda adalah Anda tidak menggunakan salah satu SQLiteOpenHelper 's metode (getWritableDatabse atau getReadableDatabase ) untuk membuka basis data.
Sebaliknya Anda menggunakan SQLiteDatabase BUKA metode. Yang tidak melakukan pemeriksaan dan pengaturan versi.
Jika saya menghapus komentar this.getReadableDatabase() dalam metode konstruktor theonUpgrade saya dipanggil tetapi saya tidak dapat menanyakan data dan mengembalikan kesalahan.
Memperkenalkan getReadableDatabase , lalu melakukan pemeriksaan dan mencoba menyalin versi yang lebih baru, tetapi versi yang lebih lama terbuka sehingga kemungkinan besar Anda akan mengalami konflik sebagai akibatnya.
Anda mungkin menemukan jawaban atas pertanyaan Metode mana yang dapat digunakan untuk mengelola berbagai versi database yang sudah ada sebelumnya? membantu (mungkin yang kedua).
Contoh Kerja
Contoh kerja berikut menggunakan kode dari jawaban yang ditautkan tetapi didasarkan pada kode dan basis data dari pertanyaan (sebagaimana dapat dipastikan).
Kelas inti yang mendasarinya adalah DatabaseAssetHandler.java , yang mencakup sejumlah metode statis untuk memeriksa dan menyalin database, semuanya terutama sebagai file dan bukan sebagai database SQLite.
Subkelas SQLiteOpenHelper, berdasarkan DatabaseHelper.java pertanyaan kelas tetapi menggunakan metode DatabaseAssethandler untuk memeriksa versi kode terhadap versi file database (meniadakan kebutuhan untuk menggunakan metode onUpgrade dan juga metode onCreate)
Terakhir, contoh menyertakan Aktivitas, MainActivity.java seperti yang biasanya Anda temukan. Kelas ini juga mengekstrak semua baris dari database dan membuang Kursor ke log.
