R.java is not generating neither with eclipse nor with Android Studio -

I'm having trouble with the development of my app, I can not go because R.java is not causing. I tried to find everything on stack overflow, but I did not get anything that worked. The problem is not only in Eclipse but also in Android studio. I checked all my XML files but could not find anything that should stop RJVA production. This is the content of my manifest.xml:

  & lt ;? Xml version = "1.0" encoding = "UTF-8"? & Gt; & Lt; Manifest xmlns: Android = "http://schemas.android.com/apk/res/android" package = "com.thenewprogramming.android.timetoswim" Android: versionCode = "1" Android: versionName = "1.0" & gt; & Lt; Use-sdk android: minSdkVersion = "17" Android: targetSdkVersion = "17" /> & Lt; Android: Android: icon = "true_android": icon = & Lt; Activity Android: name = "com.thenewprogramming.android.timetoswim.HomeActivity" android: label = "@ string / app_name" Android: Screen Orientation = "Sensor Portrait" & gt; & Lt; Intent-Filter & gt; & Lt; Action Android: name = "android.intent.action.MAIN" /> & Lt; Category android: name = "android.intent.category.LAUNCHER" /> & Lt; / Intent-Filter & gt; & Lt; / Activity & gt; & Lt; Activity Android: name = "com.thenewprogramming.android.timetoswim.AddMatchActivity" Android: label = "@ string / AddMatchActivity_ActivityTitle" Android: Screen Orientation = "sensor" & gt; & Lt; Intent-Filter & gt; & Lt; Category android: name = "android.intent.category.DEFAULT" /> & Lt; / Intent-Filter & gt; & Lt; / Activity & gt; & Lt; Activity Android: name = "com.thenewprogramming.android.timetoswim.SettingsActivity" android: label = "@ string / settingsActivity_ActivityTitle" Android: Screen Orientation = "Sensor Portrait" & gt; & Lt; Intent-Filter & gt; & Lt; Category android: name = "android.intent.category.DEFAULT" /> & Lt; / Intent-Filter & gt; & Lt; / Activity & gt; & Lt; / Application & gt; & Lt; / Reveal & gt;   
 I tried to wipe out all the other XML and which was not working, so I brought them back.  
 All help would be greatly appreciated.  
 EDIT: Someone told me immediately that the stars must start with a lowercase letter, so I did it and it worked! Unfortunately they removed this post, but I will mark the question as answer (if I know how to do this ...) 
 
 
 
 Whenever your generated R class does not occur, it indicates that some parsing with XML resources Due to the issue there is a problem in generating it.  
 Common problems are:  
 
 In your  strings.xml  for an irreversible character, for example  you  instead of < Code> you \ 're   
  layout_width  or  layout_height  tags in layout resources  
 missing namespace announcements  
 Due to the use of capitalization or spaces, hyphens or other unsupported characters, for example, convertible names that are not supported by Java  
 Car syntax error
