Question

我正在Eclipse中构建第一个Android应用程序（Luna Service Release 1（4.4.1））。我在系统上下载了所有Eclipse插件和AVD（参见截图）。

当我跑到下面时发生错误
无法在设备＆＃39; emulator-5554上安装HelloWorldAndriodApp.apk！（空值）发布已取消！

我在谷歌（包括Stack Overflow）上经历了许多与此类似的链接，并尝试了解决方案1.将ADB连接超时增加到500000 2.清理构建应用程序3.重置ADB 在所有这些练习之后，我开始得到另一个例外 [2015-11-30 12:50:19 - HelloWorldAndriodApp]安装错误：未知失败 [2015-11-30 12:50:19 - HelloWorldAndriodApp]请查看logcat输出以获取更多详细信息。 [2015-11-30 12:50:23 - HelloWorldAndriodApp]发布取消了！

由于所有这些错误，我的应用程序没有初始化，只能看到黑屏与Android＆＃39;模拟器屏幕中间的文本。

请提出一些解决方法来摆脱这些错误。

的AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
   package="com.example.helloworldandriodapp"
        android:versionCode="1"
        android:versionName="1.0" >
        <uses-sdk
            android:minSdkVersion="8"
            android:targetSdkVersion="16" />
        <application
            android:allowBackup="true"
            android:icon="@drawable/ic_launcher"
            android:label="@string/app_name"
            android:theme="@style/AppTheme" >
            <activity
                android:name=".MainActivity"
                android:label="@string/app_name" >
            </activity>
        </application>
    </manifest>

Java类

public class MainActivity extends ActionBarActivity {

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
        }
    }

activity_main.xml中

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.helloworldandriodapp.MainActivity" >

    <TextView
        android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_centerHorizontal="true"
      android:layout_centerVertical="true"
      android:text="@string/hello_world"
      tools:context=".MainActivity" />    
</RelativeLayout>

的strings.xml

<resources>
    <string name="name">Type your name</string>
    <string name="app_name">HelloWorldAndriodApp</string>
    <string name="hello_world">Hello world!</string>
    <string name="action_settings">Settings</string>
    <string name="menu_settings">Settings</string>
   <string name="title_activity_main">MainActivity</string>
</resources>

Answer 1

代码很好，应该工作，问题必须是模拟器。

PS：另外，我建议使用Android Studio进行Android开发。我最近开始使用它，让一切变得如此简单。
