我的Android应用程序在模拟器上运行，但无法在我的Android设备上运行

Question

My application works fine on android emulator. When I'm trying to run it on my device LogCat column gives me info that there is no such columns: USERNAME. On emulator my SQLite database is created normally and I can add new users and sign but in device there is an exception when I'm trying doing this.

Here is a Log file when i'm trying to create new user:

Anyone could help?

Answer 1

You may have changed the DB schema without increasing DATABASE_VERSION and thus the new app is finding the old DB.

static final int DATABASE_VERSION=2;

should fix it.

Answer 2

尝试在设备上卸载应用程序，然后重新运行它。
