无法实例化应用程序 - java.lang.ClassNotFoundException:在路径上找不到类"com.xxxxx.App":/ data/app/com.xxxxx-1.apk

Question

每次运行应用程序时这都是错误:

    E/AndroidRuntime: FATAL EXCEPTION: main
java.lang.RuntimeException: Unable to instantiate application com.xxxxx.App: java.lang.ClassNotFoundException: Didn't find class "com.xxxxx.App" on path: /data/app/com.xxxxx-1.apk

这里有一些信息:

JavaVersion.VERSION_1_8        (I cannot use 1.7 because of a library)
buildToolsVersion '24.0.0'
compileSdkVersion & target 24  (also tried 23)
gradle 2.2.0-alpha4            (also tried with 2.1.0)

我已经instant run禁用了.

我有一个名为App扩展的类Application,所以AndroidManifest.xml我有<application android:name="com.xxxxx.App"

请不要将此问题标记为重复,因为我已经尝试了所有给出的解决方案,但我无法摆脱这个错误.

 

Answer 1

您是否尝试过在其他设备/模拟器上运行该应用程序？
我曾经遇到过这个问题，因为我是我尝试运行它的设备上的第二个用户。如果是这种情况，您每次希望运行应用程序时都必须切换到主要用户（所有者）。
