私のAndroidアプリケーションはエミュレータで動作しますが、私のAndroidデバイスでは動作しません

Question

私のアプリケーションはAndroidのエミュレータで正常に動作します。私のデバイス上で実行しようとしているとき、LogCatの列には、そのような列がないという情報が表示されます：USERNAME。 エミュレータでSQLiteデータベースが正常に作成され、新しいユーザと署名を追加できますが、デバイスではこれを実行しようとしているときに例外があります。

誰でも手助けできますか？

Answer 1

デバイスのアプリケーションをアンインストールして再実行してください。

Answer 2

DATABASE_VERSIONを増やすことなくDBスキーマを変更した可能性があります。新しいアプリケーションが古いDBを検出している可能性があります。

static final int DATABASE_VERSION=2; 

を修正する必要があります。
