運行我的應用程序時，我不斷收到錯誤消息？

Question

This是當我在模擬器中運行我的應用程序時所收到的錯誤消息。

沒有什麼錯誤日誌，它並沒有真正告訴我在哪裏，錯誤是來自，但我得到這個在logcat中：

WARN/ActivityManager(51): Launch timeout has expired, giving up wake lock! 

WARN/ActivityManager(51): Activity idle timeout for HistoryRecord{44e0fb68 com.gamer.network2/.FirstActivity} 

WARN/InputManagerService(51): Window already focused, ignoring focus gain of: com.android.internal.view.IInputMethodClient$Stub$Proxy@44e98158 

ERROR/gralloc(51): [unregister] handle 0x494d08 still locked (state=40000001) 

這是我的Java的佈局，來了的時候該應用程序已啓動：（我想如果這是第一次出現，這將是哪裏出了問題，但我真的不知道。）

package com.gamer.network2; 

import android.app.Activity; 
import android.content.Intent; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.TextView; 

public class FirstActivity extends Activity { 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    TextView next1 = (TextView) findViewById(R.id.signuptext); 
    next1.setOnClickListener(new View.OnClickListener() { 
     public void onClick(View view) { 
      Intent myIntent = new Intent(view.getContext(), Screen2.class); 
      startActivityForResult(myIntent, 0); 
      finish(); 
     } 

    }); 
} 
} 

這裏是我的清單：

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
package="com.gamer.network2" 
android:versionCode="1" 
android:versionName="1.0">

<application android:icon="@drawable/newlogo2" 
android:label="@string/app_name">

       android:label="@string/app_name">

      <action android:name="android.intent.action.MAIN" /> 
      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter>

<activity android:name=".Screen3"></activity> 
<activity android:name=".Screen4"></activity>

</manifest> 

而對於佈局/主XML代碼：

</LinearLayout> 

我可以張貼任何你需要的其他代碼，以幫助我。 =]

我覺得onClickListener是按鈕而已，沒有textviews
