我的第一款android应用程序没有'；成功安装后，请不要运行

我正在制作一个android应用程序。第一个启动器活动代码为：

 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);
        }

    }
}

清单文件是：

<?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>

可能是其中一个问题的重复，与堆栈跟踪中显示的相同ShellCommandUnresponseveException异常有关：

我一直都有类似的问题。安装正常，但shell无法启动应用程序。只需像打开其他应用程序一样在设备上打开应用程序。此外，还应使用“.equals（x）而不是x==”
