我正在尝试通过adb命令启动apk,在安装apk后不久,我收到ClassNotFoundException并且应用程序崩溃了。

我的日志:

java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.sample.test.one/com.sample.test.one.MainActivity}: java.lang.ClassNotFoundException: Didn't find class "com.sample.test.one.MainActivity" on path: DexPathList[[zip file "/data/app/com.sample.test.one-1/base.apk"],nativeLibraryDirectories=[/data/app/com.sample.test.one-1/lib/arm, /system/lib, /vendor/lib]]

流程

adb install test.apk

adb shell am start -n com.sample.test.one/com.sample.test.one.MainActivity

or 

adb shell am start -a android.intent.action.Main -n com.sample.test.one/.MainActivity

我正在尝试上面adb shell commands但是应用程序无法启动,但我观察到一个场景,如果我将在Android Studio中运行代码并且应用程序安装在设备中,之后如果我将尝试&# 34; adb shell am start "命令然后它工作正常,但如果我尝试通过" adb安装apk "那么这个命令不起作用。

我偶然遇到过这种情况,但在将MultiDex添加到我的gradle后,一切都很顺利。

第1步

defaultConfig {
         minSdkVersion minVersion+
         targetSdkVersion targetVersion+

         multiDexEnabled true
     }

 dexOptions {
      incremental true
      javaMaxHeapSize "4g"
 }

第2步

添加gradle

compile 'com.android.support:multidex:1.0.0'

第3步  更改gradle属性

org.gradle.jvmargs=-Xmx4096m

请尝试这个技巧。

英语不是我的母语;请原谅输入错误。

解决方案: 看看您的App项目文件AndroidMainfest.xml,查找包含此

的活动
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>

在此范围内,请记住此活动名称属性。 使用此命令

adb shell am start -D -n com.mycompany.moba.lala/com.epicgames.ue4.SplashActivity 

将com.epicgames.ue4.SplashActivity替换为以前的名称路径。
