Question

当我在任何设备上安装我的应用程序时出现以下错误。请给我一个解决方案。我之前从未遇到过这种类型的错误。我已经发布了build，gradle，manifest等。

错误：

Answer 1

Java虚拟机时抛出ClassNotFoundException （JVM）尝试加载特定的类，而指定的类不能可以在类路径中找到

<强>唐＆＃39;吨

 android:name="android.support.multidex.MultiDexApplication"
 public class OhxeeApp extends MultiDexApplication {

<强>不要

android:name="com.example.jobinsabu.ohxee.others.OhxeeApp"
public class OhxeeApp extends Application {

Answer 2

在你的清单中

。

android:name=".OhxeeApp"
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme"
android:hardwareAccelerated="true">

Answer 3

在AndroidManifest中将应用程序名称更改为OhxeeApp：

android:name=".OhxeeApp"

Android无法实例化Multidex Application
