adb shell 我开始给出 ClassNotFoundException

Question

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

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]]

流量：

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 adb shell commands 但应用程序无法启动，但我观察到一种情况，如果我愿意运行 Android Studio 中的代码和应用程序安装在设备，然后如果我尝试“adb shell am start”命令那么它工作正常但如果我尝试通过“adb install apk" 则此命令无效。

Answer 1

我曾经遇到过这种情况，但是在我的 gradle 中添加了 MultiDex 之后，一切都很好。

步骤 1

defaultConfig {
         minSdkVersion minVersion+
         targetSdkVersion targetVersion+

         multiDexEnabled true
     }

 dexOptions {
      incremental true
      javaMaxHeapSize "4g"
 }

步骤 2

添加gradle

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

步骤 3 更改 gradle 属性

org.gradle.jvmargs=-Xmx4096m

请试试这个技巧。

Answer 2

English is not my native language; please excuse typing errors.

解决方法：看看你的 App 项目文件 AndroidMainfest.xml ，寻找 activity 包含这个

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

在此范围内，记住此 activity 名称属性。使用这个命令

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

将 com.epicgames.ue4.SplashActivity 替换为之前的名称路径。
