运行应用程序时出错:找不到默认活动

标签: android android-studio apk android-manifest unity5

我是Android Studio新手。我现在正在使用它,希望获得一些错误消息,解释为什么我的APK无法在Blue Stacks中运行。 APK是在Unity中构建的。

安装Android Studio,手机模拟器等后,我仍然无法运行APK。它说:

Error running app: Default Activity not found

Stack Overflow中有关于此错误的a post。但是,我的AndroidManifest.xml看起来很好。我也试过“使高速缓存/重新启动无效”#39;无济于事。当我去编辑配置>启动选项>指定的活动,我看不到任何活动供我选择。

以下是我的AndroidManifest:

我该怎么做才能运行APK?

*更新*

我不知道这是否有帮助。当我跑步&#39;分析APK ...&#39;时,我得到以下内容:enter image description here

*更新2 * Android Studio中的清单旁边还有一个红色感叹号,上面写着“URI未注册。”#,指向此行:

xmlns:android="http://schemas.android.com/apk/res/android"

答案 0 :(得分:1)

尝试将此代码添加到您的Manifest:

<category android:name="android.intent.category.LAUNCHER" />

答案 1 :(得分:0)

问题可能来自清单:不要为移动设备和电视机使用相同的启动器活动,而是尝试将它们分开(不太确定):

<application
  ...
  <activity
    android:name="com.example.android.MainActivity"
    android:label="@string/app_name" >

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

  <activity
    android:name="com.example.android.TvActivity"
    android:label="@string/app_name"
    android:theme="@style/Theme.Leanback">

    <intent-filter>
      <action android:name="android.intent.action.MAIN" />
      <category android:name="android.intent.category.LEANBACK_LAUNCHER" /> <!-- See here ?-->
    </intent-filter>

  </activity>
</application>

您还应该声明LeanBack支持:

<manifest>
    <uses-feature android:name="android.software.leanback"
        android:required="false" /> 
    ...
</manifest>

required属性值设置为false。如果将所需属性值设置为true,则您的应用只能在使用Leanback UI的设备上运行。

在活动xml中简单删除

activity_main.xml

参数

tools:context=".MainActivity"

干杯;)
