Android项目在Samsung S7 API 24，Nexus 6 API 24，API 23 Emulator，Pixel API 23和Galaxy Note 23 API仿真器上运行没有问题。
当我在使用API 22或21的设备或模拟器上运行它时，在第一次启动App时会抛出以下异常。

首先，尝试清理项目。面对过去的类似问题，清理和重建项目解决了我的案例。
其次，如果您的Abc Database Helper类不公开，则只能访问相同的包/文件夹。
更改
class AbcDatabaseHelper {
}
至
public class AbcDatabaseHelper {
}
此外，三星设备上可能缺少一些库和方法，如S4 Mini，S3 Mini，S4，Note 2等。某些第三方库在某些情况下可能无效。
我找到了解决这个问题的方法。它应该是一个多指标问题。当我减少依赖项的数量时，不再发生此问题。
最后我改变了
compile 'com.google.android.gms:play-services:10.0.1'
至
compile 'com.google.android.gms:play-services-maps:10.0.1'
因为我只需要地图并保留所有其他依赖项。
仍然不确定为什么它表现得像这样，显然API 23和24以与API 22及以下不同的方式处理Multidex。
希望这有助于任何有类似问题的人。
使用异常类它捕获所有异常
