我刚刚将一个应用程序重构为框架库和应用程序,但现在当我尝试在模拟器中启动应用程序时,我得到以下错误堆栈跟踪:

我有一个问题,因为我在Playstore上更新了我的应用程序.自此更新以来,抛出异常,但我没有更改与此异常相关的任何内容.

这是错误的全文:

03-19 23:32:37.418 10121 10121 …好的,这对我来说根本没有意义,我不明白为什么我在我的应用程序中收到此错误.我在android manifrest xml中注册了活动类.
java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.mobile.batteryhelper/com.mobile.batteryhelper.Battery}:
java.lang.ClassNotFoundException: Caused by: java.lang.ClassNotFoundException: com.mobile.batteryhelper.Battery in loader dalvik.system.PathClassLoader[/mnt/asec/com.mobile.batteryhelper-1/pkg.apk]
这是androidmanifest.xml.是的.Battery类也扩展了Activity.
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".Battery"
android:label="@string/app_name"
android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
我在设备上运行时遇到此错误.我一直在浏览这个问题,我很确定我没有提到的问题.我的两个活动都在AndroidManifest中声明,而intent过滤器就在那里.我没有任何库(除了v4支持库,但声明它不会改变问题).我想在我的清单代替carpedujourproductions.quickpronote.MainActivity通过.MainActivity,但仍然没有运气.我正在运行Android Studio 0.2.5,所以我找不到如何解决与Java Build Path/Order and Export相关的潜在问题
我忍不住注意到我的MainActivity图标在树的左上角有一个灰色的十字架.

没有找到值v24的资源....
像这样的一些东西我搜索并通过更改build.gradle中的以下行来解决它
compileSdkVersion 25
buildToolsVersion '25.0.2'
现在,错误消失了,它在更高的Android版本7.1.1中运行完全正常 但是当我在较低版本的android中运行它给出以下错误

</dependency>
和
<dependency>
