How to fix ERROR/AndroidRuntime(733)?

I keep getting this error every time I try to emulate pra application on the Virtual Device. The app never open, it force close every time. What can I do?

My AndroidManifest:

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


    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".Tela_Inicial"
                  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=".importacao.AndroidFileBrowser">
            <intent-filter>
                <action android:name="android.intent.action" />
            </intent-filter></activity>
    </application>
    <uses-permission 
        android:name = "android.permission.WRITE_EXTERNAL_STORAGE"/>
</manifest>

Have you added all your activities to the Android Manifest?

EDIT: A couple of extra things now you've posted your Manifest:

1. Are you sure you have the file path for Tela_Inicial right? It's not in a sub-package or anything?
2. You need to move uses-permission to before application
