Can't start app from launcher in Android

My application is able to run from the launch开发者_StackOverflow中文版er on the Galaxy Tab, but on the HTC Legend, I get the following error in logcat:

--------- beginning of /dev/log/main
D/Rosie   (  194): can't start activity: android.intent.action.MAIN
--------- beginning of /dev/log/system
I/ActivityManager(   97): Starting activity: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10200000 cmp=com.company.myapp/.Myapp }
W/ActivityManager(   97): Permission denied: checkComponentPermission() reqUid=10015

My manifest file is the following:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

  android:versionCode="1"

<uses-feature android:name="android.hardware.camera.autofocus" />
</manifest> 

Edit: Fix

Just had to uninstall from device and reinstall.

I'm the OP. I edited my question for the fix, but here it is also:

Just had to uninstall from device and reinstall.

You have an empty <uses-permission></uses-permission> element in your manifest. Try removing it.

Try deleting the line in your manifest that declares an empty permission. It's possible the system doesn't know how to handle that (see the null warning).

Delete this line:

<uses-permission></uses-permission>
