Android 如何使我的SQL数据库工作，以便它存储图像？
我的应用程序显示各种文本字段、日期和时间选择器，最重要的是，还有一个图像按钮。 图像按钮有自己的sql数据库，而文本字段、日期和时间选择器存储在另一个sql数据库中 当你点击图像按钮时，你可以选择进入画廊。我的问题是：为什么我的应用程序在点击画廊中的一张图片后崩溃。onActivityResult方法肯定有问题，但我无法解决。我的应用程序有什么问题，我如何才能使其正常工作 以下是我的活动代码：Android 如何使我的SQL数据库工作，以便它存储图像？,android,sql,Android,Sql,我的应用程序显示各种文本字段、日期和时间选择器，最重要的是，还有一个图像按钮。 图像按钮有自己的sql数据库，而文本字段、日期和时间选择器存储在另一个sql数据库中 当你点击图像按钮时，你可以选择进入画廊。我的问题是：为什么我的应用程序在点击画廊中的一张图片后崩溃。onActivityResult方法肯定有问题，但我无法解决。我的应用程序有什么问题，我如何才能使其正常工作 以下是我的活动代码： public class ReminderEditActivity extends Activity
