Android exception: Runtime exception on launching login activity

I'm an android newbie. I'm using the android studio and connecting to a device, 4.04, api 14. I created a default login activity. It throws up the following exception:
Launching application: com.noatta.www.noatta_14/com.noatta.www.noatta_14.LoginActivity.
DEVICE SHELL COMMAND: am start -n "com.noatta.www.noatta_14/com.noatta.www.noatta_14.LoginActivity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER

Anybody have a suggestion on how to prevent the read exception?

You're missing <intent-filter> in activity definition:
<activity
android:name=".LoginActivity"
android:label="#string/app_name"
android:windowSoftInputMode="adjustResize|stateHidden" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

You are missing the intent-filter and the exception states you were missing the android:exported="true" in your AndroidManifest.xml
<activity
android:name=".LoginActivity"
android:label="#string/app_name"
android:windowSoftInputMode="adjustResize|stateHidden"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

Changing default activity in android

hello I want to change default activity. But when I do that the app doesn't launch at all without any errors
<activity
android:name="com.example.dimmer.MainActivity"
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="com.example.dimmer.DevicesActivity" >
</activity>
This way MainActivty launches with no proble. It also goes to Device activity when I press the button. So everything works fine.
Now I need DevcieACtivty to be default one.
I change Manifest like that
<activity
android:name="com.example.dimmer.DevicesActivity"
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="com.example.dimmer.MainActivity" >
</activity>
but now app doesn't launch. no errors. nothing is written in console.
it's just doesn't do anything,
what might be a problem?
It starts to write the following error
ActivityManager: Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.example.dimmer/.MainActivity }

Since you've defined your package as "com.example.dimmer", you can remove package name and use just the name of Activity with dot in front:
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".DevicesActivity"
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=".MainActivity" >
</activity>
</application>
Moreover, check your Run configuration settings in Eclipse. If your launching activity was set to MainActivity, and in manifest you make DevicesActivity as main, your app might not start when launching via Eclipse. Click arrow for RUN icon and choose "Run Configurations",
Then make sure you choose DevicesActivity as Launch:

Uninstall the app on your phone, and redownload it.

Make sure you implement setContentView in onCreate method.
In other way try clean the project Project > Clean and run it.

I am not sure but Now you can some step a head.
such as
1. delete Android.R (in above in your activity )
2. or replace package.R for example , com.example.name.R
3. check you res folder or sub-folder resources .
such as layout attribute right or not.
4. Delete gen and bin folder.
5. clean your project thus: project=>clean
6. restart your eclipse.
Remember that if your resource not found then show this type error.
Best of luck!

Click arrow for RUN icon and choose "Run Configurations"
Android Application =>select project
open Target tab
select Always prompt to divice
click run and select Divice online

Cannot use some Android emulators: Permission Denied

I have problems running the latest Android emulators like "Nexus 7, Android 4.1.2". The emulator can start, but I can't deploy on it (by Maven) which probably depends on this problem: When I switch on the phone to the Apps view, I get "Unfortunately, launcher has stopped" and LogCat gives me the following output:
01-02 14:30:26.313: W/ActivityManager(151): Permission denied:

extras) } from android (pid=970, uid=10014) is not exported from uid
1000 due to receiver
com.android.settings/com.android.settings.widget.SettingsAppWidgetProvider
My AndroidManifest looks like this:
<uses-permission android:name="android.permission.INTERNET" />
<uses-sdk
android:minSdkVersion="5"
android:targetSdkVersion="7" />
<application

android:theme="#android:style/Theme.NoTitleBar">
<intent-filter>

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

<uses-library android:name="com.google.android.maps"
android:required="true" />
</application>
Any ideas?

Are you trying to send the android.appwidget.action.APPWIDGET_UPDATE broadcast somewhere in your code? This is an Android OS broadcast, so you won't have permission to use it if you are...

Android app built in eclipse wont run on phone

I've built an app that runs fine on the emulators, and says that it installs ok on the phone. However, on trying to run it an error pops up saying 'Application is not installed on your phone'. So I tried running the app through eclipse on the phone and I got this error in the console:
[2012-05-01 12:00:02 - MAD Assignment] ActivityManager: Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.mad.assignment/.MainMenu }

From looking for the solution elsewhere it sounds as though it could be a problem in the manifest file, so here is mine:
<?xml version="1.0" encoding="utf-8"?>

Any ideas what this security exception is pointing to? Thanks!

The java.lang.SecurityException you are seeing is because you may enter two entries pointing to same activity. Remove the second one and you should be good to go.
You may be declared the activity 2 times in the manifest with different properties, like :
<activity android:name=".MainMenu"> </activity>
and
<activity android:name=".MainMenu" android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
You should remove the unwanted one from the manifest

Set android:debuggable="true" under application.

You have an activity named
<activity android:name=".MainMenu"></activity>
Which is the Intent'ed activity from the launcher. But the activity to which you gave permission is "Mainmenu". Remove it. Add the permission and etc to the ".Mainmenu" which is blank now.
ie,
The 'activity' group should be
<activity
android:name=".MainMenu"
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=".Diary"></activity>
<activity android:name=".Info"></activity>
<activity android:name=".MapMenu"></activity>
<activity android:name=".RSSMenu"></activity>
<activity android:name=".DiarySchedule"></activity>
<activity android:name=".DiaryAddEntry"></activity>
<activity android:name=".DiaryEditEntry"></activity>
<activity android:name=".DiaryDetailed"></activity>
<activity android:name=".RSSDetailed"></activity>
<uses-library android:name="com.google.android.maps"/>
<activity android:name=".MapMain"></activity>
<activity android:name=".RSSFeedView"></activity>
<activity android:name=".MapWhatsNearPreferences"></activity>
<activity android:name=".RoutePath"></activity>
And remove the duplicates as well. Why did you add so many duplicate 'activities' ?

java.lang.SecurityException: Permission Denial: starting Intent

I am a newbie to Android application development... When i try to run my application i am getting a security exception as Permission Denial... though i am able to open my application i am unable to proceed to any of the process... Application doesn't access the web service... Plz help me out...
The following is the exception message I receive,
[2012-01-11 11:02:09 - eCalc] ActivityManager: java.lang.SecurityException: Permission Denial: starting Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10000000 cmp=com.anb.eCalculator/.LoginActivity } from null (pid=-1, uid=-1) requires android.permission.INTERNET

<uses-permission android:name="android.permission.INTERNET" />
Add this above line in your manifest file after your <uses-sdk> line.

Add this permission to your manifest file.
<uses-permission android:name="android.permission.INTERNET" />

I fixed it .
Click on "Run" and "Edit configuration". Select the activity you want to launch.
