成功安装后，我的第一个android应用程序未运行

Question

我正在制作一个Android应用程序。 第一个启动器活动代码是：

 package com.example.test;   
    import android.app.Activity;
    import android.content.Intent;
    import android.content.SharedPreferences;
    import android.os.Bundle;
    public class FirstPage extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        SharedPreferences sp = getSharedPreferences("STATE",0);
        String x = sp.getString("typeOfUser","");

       if(x==""){
            setContentView(R.layout.activity_first_page);
            Intent intent = new Intent(this,LoginOrRegister.class);
           startActivity(intent);
      }
        else {
            setContentView(R.layout.lat_lon);
        }

    }
}

清单文件为：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.test"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="19" />
    <uses-permission android:maxSdkVersion="19" android:name="android.permission.INTERNET"/>

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.test.FirstPage"
            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=".LoginOrRegister" />
        <activity android:name="Registration"></activity>
        <activity android:name="SignIn"></activity>
    </application>

</manifest>

但是，当运行这个程序。 有错误：

运行时无命令输出：设备模拟器-5554上的“ am start -n com.example.test / com.example.test.FirstPage -a android.intent.action.MAIN -c android.intent.category.LAUNCHER”

这是我的堆栈跟踪：

可能与以下问题之一重复，这些问题与堆栈跟踪中显示的ShellCommandUnsensitiveException异常有关：

• Android CTS在模拟器上显示ShellCommandUnsensitiveException
• Android应用程序不会在模拟器中显示
