  <p>keep getting error messages when I try to launch any mobile app with android. These errors are not predictable - sometimes (like once out of 10 times) a miracle happens and everything works. But most of the time I get this error:</p>
  
  <p><code>[ERROR] C:\Program Files\Titanium Developer\android-sdk-windows\tools\adb.exe 
  error: protocol fault (no status)</code></p>
  
  <p>followed by this error later on:</p>
  
  <p><code>[DEBUG] Waiting for device to be ready ...
  [TRACE] adb devices returned 0 devices/emulators
  ......
  [ERROR] Timed out waiting for emulator to be ready, 
  you may need to close the emulator and try again</code></p>
  
  <p>The emulator starts and I get the locked screen but somehow the connection with it is lost.</p>
  
  <p>I tried launching the emulator separately from a batch file as someone else suggested before I open the ti developer but I get the same errors.</p>
  
  <p>Even if it runs correctly once, if I make changes and want to relaunch (without stopping or closing the emulator) I always get the errors above. I thought we are supposed to be able to keep reusing the emulator once it's up and running but for me it never works like that.</p>
  
  <p>When i try to run from eclipse it used to give the following message <code>Failed to install Demo.apk on device 'emulator-5554': timeout</code></p>
  
  <p>I want to run the same application without killing adb server or without closing the emulator again.</p>
  
  <p>Please any help would be appreciated lot!!!!!!!!!</p>
