Question

我是Android的编程新手，所以我开始关注互联网上的教程，非常简单的东西但是当我编译它以便在模拟器上运行它总是说：“不幸的是你的程序已经停止了”我的设备模拟器（nexus 4）所以我认为我的java代码有错误。

所以我用通常的“hello world”创建了一个未经修改的全新项目，所以它应该可以工作，但是当我要运行时它看起来是一样的。 “不幸的是你的程序已经停止了”。这是我的控制台上显示的内容。

也许它与我正在使用的API版本有关？

Answer 1

将targetSdkVersion用作19。

<uses-sdk
    android:minSdkVersion="15"
    android:targetSdkVersion="19" />

There is a problem with API 20

希望它有所帮助。

Answer 2

你必须像这样设置正确的目标和minsdkversion：

<uses-sdk android:minSdkVersion="8"
      android:targetSdkVersion="19" />

Answer 3

像这样更改你的清单;

<?xml version="1.0" encoding="utf-8"?>

<uses-sdk android:minSdkVersion="8"
  android:targetSdkVersion="19" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MyActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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