安卓开发新手：安卓模拟器总是有应用崩溃

【问题标题】：New to android Development: Android Emulator always has apps crash安卓开发新手：安卓模拟器总是有应用崩溃
【发布时间】：2014-07-09 17:50:28
【问题描述】：

我是 Android 开发新手（请善待），我尝试在两台不同的机器上设置我的开发环境，一台使用 AMD 处理器，另一台使用 Intel 处理器。在两台机器上，我都无法在模拟器中打开应用程序。我花了几个小时寻找问题，现在我需要帮助。

在我多说之前，我想提一下，在我安装 32 位 JDK 之前，eclipse 不会在我的机器上运行，即使我正在运行安装了 64 位 jdk 的 64 位机器。 （会不会跟这个有关系？）

请查看我的 imgur 链接以了解我在做什么。 Imgur Link

让我告诉你们我在做什么，你们可以告诉我我做错了什么。

在 Package Explorer 中，我右键单击，然后转到 New>Android Application Project。

然后我更改应用程序名称、包名称和所需的最低 SDK。

然后单击下一步，直到到达“创建活动”菜单，并选中“创建活动”旁边的框，然后选择“空白活动”。

然后我点击下一步，然后点击完成。

我认为这足以让我能够在模拟器中运行它，所以为了测试模拟器，我选择运行配置，选择我的应用程序，然后选择“com.johndavisdesign.helloworld.MainActivity。

我将目标设置为模拟运行 Android 4.4 的 Nexus 10 的 AVD。

这会启动模拟器，但不会安装程序，无论我等待多长时间。如果我在不关闭模拟器的情况下再次运行配置，程序将打开，但会显示“不幸的是，HelloWorld 已停止。”

我的控制台显示：

我做错了什么？

编辑：

这里是 MainActivity.java：

package com.johndavisdesign.helloworld;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;


public class MainActivity extends Activity {

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


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}

}

编辑 2：

<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.johndavisdesign.helloworld.MainActivity" >

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/hello_world" />

</RelativeLayout>

【问题讨论】：

  • MainActivity.onCreate() 的第 14 行是什么？
  • 我在原帖中添加了 MainActivity.java。
  • 发布你的activity_main.xml
  • 我刚刚发布了它。感谢您查看我的问题。
  • 在新建项目向导中，您指定要使用 API20 Android 4.4 KitKat Wear 进行编译。创建一个新项目并使用普通的 API19 Android 4.4 KitKat 进行编译。它基本上认为你想创建一个 Android Wear 项目，我假设你没有。

【解决方案1】：

您正在制作一个 Android Wear 项目，您真的想要吗？您是否尝试过制作一个“普通”的 Android 项目？

【讨论】：

  • 你是对的。更改“编译方式”并更改我的 AVD 操作系统后，一切正常。感谢您的帮助！
