I've an exception when run android application?

I've an exception when run android application? - android

I think the error is from this manifest file ?!! when i want to start this activity "SearchResultForm" i have the exception ??
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="ayanoo.forms"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="#drawable/search" android:label="#string/app_name">
<activity android:name=".MainActivity" android:label="#string/app_name" android:launchMode="standard">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="PersonDataForm" android:label="#layout/person_data_form"></activity>
<activity android:name="SearchResultForm" android:theme="#style/CodeFont"></activity>
<activity android:name="SendMessageForm" android:theme="#style/CodeFont"></activity>
</application>
<uses-sdk android:minSdkVersion="3" />
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION"></uses-permission>
</manifest>

You should have every activity of your appliaction listed within manifest file, like this:
<application android:icon="#drawable/ok" android:label="Application name">
<activity android:name=".main_screen.MyActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
</application>

Your manifest has wrong links to your Activities (except the MainActivity).
You have:
<activity android:name="SearchResultForm" android:theme="#style/CodeFont"></activity>
Try to use:
<activity android:name=".SearchResultForm" android:theme="#style/CodeFont"></activity>
Pay attention to the dot.

AppIcon will showed twice on device with Android App

When i install my android application on the device, the AppIcon will appear twice.
This means: there are two separate app-icons. Both icons launch the same app version. If I remove one app-icon, the other disappears also. If i reinstall them, it appears twice again.
How can i avoid this?
This is my AndroidManifest.xml:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.******"
android:versionCode="1"
android:versionName="1.0">
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-sdk
android:minSdkVersion="16"
android:targetSdkVersion="22" />
<application
android:name=".MainApplication"
android:allowBackup="true"
android:label="#string/app_name"
android:icon="#mipmap/ic_launcher"
android:theme="#style/AppTheme">
<meta-data android:name="com.bugsnag.android.API_KEY"
android:value="524b0194108e90ae383189e509746766"/>
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
android:windowSoftInputMode="adjustResize">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />
<activity
android:name=".SplashActivity"
android:theme="#style/SplashTheme">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

It's because of the intent-filter. Only one activity should have
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
Any activity having this intent filter will be shown in the launcher.

show 2 apps when debugging in android

When I debug and install app in device, it's show 2 apps install in device (one open with Splashscreen & another open without Splashscreen ) . Guide me, what I'm doing wrong.
here is my manifest file.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.soft.prmk.alle"
android:versionCode="1"
android:versionName="1.0" >
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<application
android:hardwareAccelerated="true"
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".SplashScreen"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

You have two Launcher Activities: MainActivity and SplashScreen. Remove one of those. Try this:
<?xml version="1.0" encoding="utf-8"?>
android:versionCode="1"
android:versionName="1.0" >
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<application
android:hardwareAccelerated="true"
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity
android:name=".SplashScreen"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
<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>

You have two LAUNCHER thats the issue
<category android:name="android.intent.category.LAUNCHER" />
Make it DEFAULT in MainActivity.
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>

You have 2 launcher activities, remove intent-filter from one. I think SplashScreen should be launcher activity so remove from MainActivity
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

Android showing error while running

i have 2 activities AndroidSlite.java and SqLiteAdapter.java.. my manifest.xml file is given below.it shows No launcher activity found .while running
please help me with the code
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.cerebtec.androidsqlite"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<activity android:name="AndroidSQLite"></activity>
</application>
</manifest>

You have to enclose the intent filter around the launcher activity, in order to declare your launcher activity. E.g.
<activity android:name="AndroidSQLite"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
this way you are telling android that the launcher activity is AndroidSQLite

Use :
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

Android manifest.xml problems

Following this: http://developer.android.com/training/basics/firstapp/starting-activity.html I am confused when editing the Android Manifest.xml file. It says that the file should contain this:
<application ... >
<activity android:name="com.example.myapp.DisplayMessageActivity" />
...
</application>
My android manifest.xml looks like this:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.nick.myfirstapp"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="4"
android:targetSdkVersion="15" />
<application android:label="#string/app_name">
<activity android:name="com.nick.myfirstapp.DisplayMessageActivity" />
...
</application>
</manifest>
and when I run the app everything goes fine except it says : "No Launcher activity found!
The launch will only sync the application package on the device!" Is this something missing from the android manifest.xml file?

declare Your Activity in AndroidManifest.xml as for Showing In Launcher as:
<application android:label="#string/app_name">
<activity android:name="com.nick.myfirstapp.DisplayMessageActivity" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
see for more info how we set an activity which so in Launcher :
http://developer.android.com/reference/android/content/Intent.html
http://developer.android.com/reference/android/app/Activity.html

You need to change you manifest to the following. Doing this will tell Android that you want this Activity to be displayed in the Launcher using your icon.
<application android:label="#string/app_name" android:icon="drawable icon resource here">
<activity android:name="com.nick.myfirstapp.DisplayMessageActivity" android:label="Your Label">
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
In the docs the used ... to show that your normal code goes here. What you're doing is fine for non-launcher Activities.

You are missing the launcher intent and therefore the app finds no activity to launch at the start.
You need to lay out the activity like so:
<activity
android:name=".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>

package="com.example.myfirstapp"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.example.myfirstapp.DisplayMessageActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

how to start a MapActvity from Activity

i'm trying to start a map activity from a normal Activity.
But keep getting the error:
10-20 10:47:08.828: ERROR/dalvikvm(1102): Could not find class 'com.xxApp.MapAnalyseActivity', referenced from method com.xxApp.xxAppActivity$1.run
10-20 10:47:11.578: ERROR/AndroidRuntime(1102): java.lang.NoClassDefFoundError: com.xxApp.MapAnalyseActivity
when i try to do:
startActivity(new Intent(xxAppActivity.this, MapAnalyseActivity.class));
xxAppActivity.this.finish();
Here is my manifest
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.xxApp"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="7" />
<uses-permission android:name="android.permission.INTERNET" />
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".xxAppActivity" android:label="#string/app_name" android:theme="#style/xxTheme">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:label="#string/mapAnalyse" android:name="MapAnalyseActivity" android:configChanges="orientation|keyboardHidden" android:theme="#style/xxTheme">
<intent-filter>
<action android:name="com.xxApp.MapAnalyseActivity" />
</intent-filter>
</activity>
</application>

Your manifest.xml should look like this
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.xxApp"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="7" />
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".xxAppActivity" android:label="#string/app_name" android:theme="#style/xxTheme">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:label="#string/mapAnalyse" android:name="MapAnalyseActivity" android:configChanges="orientation|keyboardHidden" android:theme="#style/xxTheme"/>
<uses-library android:name="com.google.android.maps"/>
</application>
<uses-permission android:name="android.permission.INTERNET" />
</manifest>

Check that MapActivity is in the Same Folder ?
or try giving full path in manifest as
com.packagename.mapactivity
