Why my signed apk crashes?
<p>I've signed an app with a sign which I've created. I've installed this apk in my phone and this is ok, but when I've tried to open the app crashes (doesn't show any activity), and it doesn't give me the posibility to watch the log (this dialog doesn't have the report button)</p>

<p>The problem is the sign which I've signed the app. I've tested with other sign and the app opens perfectly. I can't post any information about the creation of the sign, but only I can say I've used:</p>

<p>Letters and _ character in alias </p>

<p>Letters, numbers and - character in password</p>

<p>50 in years</p>

<p>and Letters in name </p>

<p>others field are blank.</p>

<p>The main problem is that the app is published in the google play, so How I can publish a new signed apk without to unpublish this app and create a new app?</p>
