我正在Eclipse中構建第一個android應用程序(Luna Service Release 1(4.4.1))。我在系統上下載了所有Eclipse插件和AVD(請參閱截圖)。在Eclipse上運行'Hello world'android應用程序時遇到一些錯誤

ADV created

當我跑到下面出錯
無法在設備上安裝HelloWorldAndriodApp.apk「模擬器 - 5554! (空) 發佈取消!

我已經通過在谷歌類似這樣的很多鏈接了(包括堆棧溢出),並也嘗試瞭解決方案1.增加亞行連接超時500000 2.清潔構建應用程序3.重置ADB enter image description here 畢竟這個練習我開始得到另一個異常
[2015-11-30 12:50:19 - HelloWorldAndriodApp]安裝錯誤:未知失敗 [2015-11-30 12:50:19 - HelloWorldAndriodApp]請檢查logcat輸出更多細節。 [2015-11-30 12:50:23 - HelloWorldAndriodApp]啓動取消!

由於所有這些錯誤,我的應用程序沒有初始化,只能在模擬器屏幕中間看到帶有'Android'文本的黑屏。

請建議一些解決方案來擺脫這些錯誤。

AndroidManifest.xml中

<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> 

的Java類

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>

發佈您的代碼。如果你把你的日誌貓異常的細節,它會更容易理解。 –

切換到Android Studio –

你在設備上測試過嗎? –

的代碼是好的,應該工作,這個問題必須與仿真器。

PS:另外,我建議使用Android Studio進行Android開發。我最近開始使用它,使一切變得如此簡單。
