Question

我的应用程序在调试模式下运行正常，但在启用proguard并生成签名apk后崩溃：

我正在使用android studio 1.5构建apk。

请在下面找到崩溃日志：

请在下面找到我的proguard-rules文件：

-dontwarn org.apache.**
-dontwarn android.net.**
-dontwarn com.alexvasilkov.**
-dontwarn android.content.**
-dontwarn android.graphics.**
-dontwarn android.util.**
-dontwarn com.squareup.picasso.**
-dontwarn android.view.**

Answer 1

SQLite不区分大小写。所以A和a是同一个名字。您需要更改列的名称。

使用proguard Android后数据库崩溃
