Launcher intent is in manifest, but no launcher activity found

I'm pretty new to android development. I created a project using android studio, and chose my first activity to be a login activity. After changing some basic stuff in the layout/trying to add some functionality in java, thought I'd do a test run. While trying to build apk and install the app, it installs fine on my phone but AIDE (A development android app) says that no launcher activity is found. Here's my manifest file:
<!-- To auto-complete the email text field in the login form with the user's emails -->
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.READ_PROFILE" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".LoginActivity"
android:label="#string/app_name"
android:windowSoftInputMode="adjustResize|stateVisible" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.categor.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
So what am I missing? I've searched a lot but I ant find an answer that applies to my scenario. Any help would be appreciated. Thanks

It Should be
<category android:name="android.intent.category.LAUNCHER" />

Can't install APK correctly on device

I have built & sign my apk by Eclipse ADT as it is describes (export and sign by creating a new key). But it can't be install on real device while an errors occurs, such as "installer package error". I have no Android device & sent my apk to friends by email. I'm using AVD and everyth is fine with it. Any suggestions? Thanx guys.
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.XXXX.YYYY"
android:versionCode="0"
android:versionName="0.9.2" android:installLocation="internalOnly">

android:parentActivityName="com.XXXX.YYYY.ActivityMain"
android:excludeFromRecents="true"
android:configChanges="orientation|screenSize">
</activity>
</application></manifest>
UPD: apk installs good, but the error occurs if choose Open (see screenshot). After that app works fine. But on tablet if try open app it says "App deleted".
UPD2: add supporting API 4+ meta tag for the 2nd activity, but it takes no effect
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.XXXX.YYYY.ActivityMain" />

You probably need to make sure your device and your friend's devices can install apps that are not from the play store.
This is a feature you have to specifically set, or else apps that are outside the play store will not install.
Here is how to set it:
Open settings
Find the Security settings (Pre 4.0 it is under Applications)
Look for a setting that says Unknown sources, or non-market apps
Enable that setting
Everything should work after that!
Here is an article with pictures if you are still confused :)

Your example was missing the closing </manifest> and android:enabled. I'm not sure if the latter would prevent a device from fully installing it but the first one would.
I've also had issues using the full activity names in the past, so you may want to try using simplifying them to see if it helps.
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme"
android:hardwareAccelerated="true"
android:allowBackup="true">
<activity
android:name=".ActivityMain"
android:label="#string/main_activity_title"
android:enabled="true"
android:permission="android.permission.INTERNET"
android:launchMode="singleTop" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".ActivityDetails"
android:parentActivityName=".ActivityMain"
android:excludeFromRecents="true"
android:configChanges="orientation|screenSize">
</activity>
</application>
</manifest>

Is "Unknown sources" option under "security" allowed on device?

My problem was a duplicate internet permission request on Manifest! When I remove that from activity app was run normally.

Googlemaps on android is showing grey screen

I've just gotten my google maps application to not crash on startup, but now, when it opens, it just shows a grey/white background and buttons for zooming. I searched the web and I found that this may be a problem with my API-key, so I got a new key from google, but this didn't work either.
Here's a screenshot of how it looks.

Anyone got any tips for this?

I've got the same problem as you, everything worked ok on emulator but on the real device it was gray surface with zoom buttons.
Then I tried other devices and it works. All other phones have original (stock) firmware, only I have one with custom firmware.
lease first check that everything works fine on emulator, then check on the device with stock firmware and let us know the result.

The problem may not be with your API key, but the authorized apps in the API console. Make sure you registered the correct key(s) and package names with the Google API console. Specifically, if you are compiling and launching directly from eclipse, you are probably signing in debug mode. If so, you need to add your debug key hash + package name to the allowed applications in the API console.

app appears in Manage Applications, but not on the main menu

I'm using Eclipse to make an Android app. I've used it before and not had this problem. The console says everything installed ok, so I'm a little confused. I'm not sure what is relevant from logcat, but I can post it if you think that would help.
I've restarted Eclipse, ADB, the emulator, and the Mac several times in various orders and nothing has helped. I know it must be something simple but I haven't played around with this in a few months.
Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.hyser.pinpoint"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="10" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
</application>
<activity android:name=".pinpoint" android:label="pinpoint">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

Your Activity needs to be inside of your application tag in your manifest
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity android:name=".pinpoint" android:label="pinpoint">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
It's a similar issue to this:
Unable to start Service Intent

Your <activity> tag needs to be in the <application> block.

Is it possible your manifest does not refer to any activities? If you install an app with no activities in the manifest you will get this behavior.

How to call correctly run few class (intents)?

I'm beginner in Java Android developing. I'm using Eclipse SDK 3.6.1 version. I'm trying to do this thing: in first class (layout - main.xml) is button "hello", it calls new class (layout - second.xml), in this class are button "hello2", it calss new class. I can't do this cause when I push first button "hello" I getting this messages "The aplication (xxxx) has stopped unexpectedly. Please try again". How to resolve this problem. I think problem is in AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="net.kodinis_raktas"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".veiksmas"
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=".second" >
<intent-filter>
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity android:name=".lock"></activity>
<intent-filter>
</intent-filter>
</application>
<uses-permission android:name="android.permission.SEND_SMS">
</uses-permission>
<uses-permission android:name="android.permission.RECEIVE_SMS">
</uses-permission>
<uses-sdk android:minSdkVersion="3" />
</manifest>

Use adb logcat, DDMS, or the DDMS perspective in Eclipse to examine LogCat and look at the stack trace associated with your error. That will give you more information.
I would recommend getting rid of the <intent-filter> elements from .second and .lock, since you are not using them. If your error is coming from trying to start .second, the existence of your category-only <intent-filter> may well prevent that activity from being started.

In my limited experience with android I think you need to add this line after activity android:name=".second"
android:label="#string/app_name">
