My applications won't appear on my home screen? (android) - java

I'am making apps for android using eclipse but suddenly when I was using the emulator the apps stopped appearing on my home screen and when I check in the Application manager they are installed but I can't access them and I tried installing the app on my android phone and the same thing also happened so any clue how to fix this, that would be great. thanks
edit:
The app starts correctly when I launch it from eclipse but the icon won't appear on my home screen so I can't access it
here is my mainfest code:
<uses-sdk
android:minSdkVersion="5"
android:targetSdkVersion="18" />
<supports-screens android:smallScreens="true"
android:normalScreens="true"
android:largeScreens="true"
android:xlargeScreens="true"
android:anyDensity="true" />
<uses-permission android:name="android.permission.SET_WALLPAPER"/>
<uses-permission android:name="android.permission.SET_WALLPAPER_HINTS"/>
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.Moon.khwallpaper.MainActivity"
android:label="#string/app_name"
android:screenOrientation="portrait" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity
android:name="com.Moon.khwallpaper.Menu"
android:label="#string/app_name"
android:screenOrientation="portrait" >
<intent-filter>
<action android:name="android.intent.action.MENU" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.Moon.khwallpaper.SET2"
android:label="#string/app_name"
android:screenOrientation="portrait" >
<intent-filter>
<action android:name="android.intent.action.SET2" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</application>
</manifest>

Try removing the intent-filter of your MainActivity and changing the Menu intent-filter to:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
EDIT:
Your logcat suggests that you are trying to start an activity with an action that is not set (or set incorrectly).
It's looking for the action com.Moon.khwallpaper.SET2 while what you have set is com.example.wallpaper.SET2.
I believe changing the latter to the former should work.

try this
<uses-sdk
android:minSdkVersion="5"
android:targetSdkVersion="18" />
<supports-screens android:smallScreens="true"
android:normalScreens="true"
android:largeScreens="true"
android:xlargeScreens="true"
android:anyDensity="true" />
<uses-permission android:name="android.permission.SET_WALLPAPER"/>
<uses-permission android:name="android.permission.SET_WALLPAPER_HINTS"/>
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.example.wallpaper.MainActivity"
android:label="#string/app_name"
android:screenOrientation="portrait" >
<intent-filter>
<action android:name="com.example.wallpaper.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.example.wallpaper.Menu"
android:label="#string/app_name"
android:screenOrientation="portrait" >
</activity>
<activity
android:name="com.example.wallpaper.SET2"
android:label="#string/app_name"
android:screenOrientation="portrait" >
</activity>
</application>
</manifest>

I have warning "App is not indexable by Google Search; consider adding at least one Activity with an ACTION-VIEW intent filter. "

After the update, the following warning appeared in the studio:
“App is not indexable by Google Search; consider adding ACTION-VIEW intent filter. See issue explanation for more details. more ... (Ctrl + F1) »
How to fix it?
My Api is 28.
Here is my manifests:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.omen.serverforcofe" >
<uses-permission android:name="android.permission.NFC"/>
<uses-feature android:name="android.hardware.nfc" android:required="true" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme"
>
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:launchMode="singleTop">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="android.nfc.action.NDEF_DISCOVERED" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="text/plain"
/>
</intent-filter>
</activity>
</application>
</manifest>
<activity
android:name=".MyActivity"
android:screenOrientation="portrait"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
</intent-filter>
</activity>
Adding this intent filter to one of the activities declared in app manifest fixed this for me.

Play Store says app is incompatible with phone tested on

The Play Store says that my app is incompatible with all the devices that I have, but that also includes the phone that I tested it on. Below is my Manifest file. I tested it on my Nexus 5X running Nougat, but the Play Store says that the app is incompatible with that phone of mine. Thanks a lot !

Android Cordova App crashes with ClassNotFoundException?

I have a problem with an android app. The following is the error message I get:
11-06 18:15:02.606: E/AndroidRuntime(2424): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{de.wiedemann.mobile/de.wiedemann.mobile.WIEDEMANN}: java.lang.ClassNotFoundException: Didn't find class "de.wiedemann.mobile.WIEDEMANN" on path: DexPathList[[zip file "/data/app/de.wiedemann.mobile-1/base.apk"],nativeLibraryDirectories=[/vendor/lib, /system/lib]]
I tried the following things:
Delete R.java
Clean project
Check all dependencies under project preferences -> order and export
Uncheck "Is Library" under Tab "Android" under Project Preferences
Restart Eclipse
Try another workspace
Nothing works. Anyone knows how this error comes and how I can resolve it?

EDIT:
Just simply rename the android:name in your activity tag to wiedemann.app.WIEDEMANN. After watching the screenshot

it came to my mind I was proposing wrong answer previously.
Or Just paste this in manifest.xml:

rename package path (in Eclipse, not in Manifest) of WIEDEMANN.java into wiedemann.app > de.wiedemann.mobile (as you can see in gen folder correct package name). Please, change symbols to lower case. Use F2 hot key in order to rename;)

android app doesnt crash after installiation

So I have very weird problem with android app that I developed that I really do not understand how to address.
Description of the problem: When I run the app in my emulator(and many other emulators) the app works perfectly, but when I list it on Google Play and some user download the app, it automatically crashes. so I just wonder if my androidmainfest is properly written.
*the program written in esclipse, java, android.

You have posted only your manifest and not the logs. My guesses based on that is the problem may be within your package declaration, rest everything seems fine.
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.app".....
The package should be unique and its like what we call package in java world. You have declared it as com.app whereas your app is using com.example.... package. Also com.app maybe used by other app.The package name defines your application's identity.
Once you publish your application, you cannot change the package name. As the package name defines your application's identity, so if you change it, then it is considered to be a different application and users of the previous version cannot update to the new version. So you may have to upload another app with different package name.
Try getting logs(use crashlytics) for your crash and we can look into it for the root cause.

Setting Wrong Application Name

I have my application named Umall but it is replaced by Slash that is my First Activity i am stuck with that small problem don't know how to handle it.. i gave application name directly in application lable
My Manifest.XML is
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.ef.umall"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="15"
android:targetSdkVersion="19" />
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="#drawable/app_logo"
android:label="Umall"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="" >
</activity>
<activity
android:name=".activity.SplashActivity_"
android:label="#string/title_activity_splash" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".activity.HomeActivity"
android:label="#string/title_activity_home" >
</activity>
<activity
android:name=".activity.ProductsListActivity_"
android:label="#string/title_activity_products_list" >
</activity>
<activity
android:name=".activity.ProductDetail_"
android:label="#string/title_activity_product_detail" >
</activity>
<activity
android:name=".activity.CartActivity_"
android:label="#string/title_activity_cart" >
</activity>
<activity
android:name=".activity.ProductActivity_"
android:label="#string/title_activity_product" >
</activity>
<activity
android:name=".activity.UmallBaseActivity_"
android:label="#string/title_activity_umall_base" >
</activity>
<activity
android:name=".activity.ShopingChart"
android:label="#string/title_activity_shoping_chart" >
</activity>
</application>
</manifest>
Try to define the application name in your string.xml file and then replace this line :
<application
android:allowBackup="true"
android:icon="#drawable/app_logo"
android:label="#string/appname"
android:theme="#style/AppTheme" >
Where "appname" is a string in string.xml like :
<string name="appname">Umall</string>
can have a label attribute. If it's absent the label is inherited from the parent component (either Activity or Application). So using this, you can set a label for the launcher icon, while still having the Activity with it's own title.
so change this
<activity
android:name=".activity.SplashActivity_"
android:label="#string/title_activity_splash" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
to this
<activity
android:name=".activity.SplashActivity_"
android:label="#string/title_activity_splash" >
<intent-filter android:label="Umall">
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
better to use #string/app_name
