My android app is not being displayed in the app drawer?

Closed 8 years ago.
Before labeling this as a duplicate, please read. I have successfully installed an Android application I developed on Eclipse on to two different platforms: one emulator (Blue Stacks) and one actual device. Like I said, the app installs just fine on both platforms, but it doesn't appear on the list of apps that can be launched. When I go to settings, I can see the app on the list of installed applications, and it lets me uninstall it, but not open it. I've spent hours trying every remedy online, but nothing works. My app is only one activity, so it should be simple, but this is the first app I've developed. I'll attach my manifest xml file below.
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.teamjava.theultimatetipcalculator"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="14"
android:targetSdkVersion="19" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.teamjava.theultimatetipconverter.MainActivity"
android:screenOrientation="portrait" >
</activity>
<intent-filter>
<action android:name="android.intent.action.MainActivity" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</application>

You should probably try using the same package name for the app and location of your activity.
You have:
package="com.teamjava.theultimatetipcalculator"
android:name="com.teamjava.theultimatetipconverter.MainActivity"
Try
package="com.teamjava.theultimatetipcalculator"
android:name="com.teamjava.theultimatetipcalculator.MainActivity"
or
package="com.teamjava.theultimatetipconverter"
android:name="com.teamjava.theultimatetipconverter.MainActivity"
EDIT -
Also try placing the intent filter inside the activity. This is how my manifest looks on all my apps
<activity
android:name="com.example.exampleapp.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>

Change:
<action android:name="android.intent.action.MainActivity" />
to:
<action android:name="android.intent.action.MAIN" />

Have you checked your console in Eclipse? Sometimes, your program can compile fine, but display errors in the console on startup.

Android app is not showing installed on emulator and my device

I have tried converted my android app from eclipse to android studio project and app is working on testing on emulator and my real device but I couldn't find it when trying to exit the app .. After publishing to the store I got the same issue + app is never open .. after installing I just got uninstall only on google play store .. please help :)
this is app url to the store : https://play.google.com/store/apps/details?id=com.linkedtalents.app&hl=en
Here is my manifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.linkedtalents.app"
android:versionCode="10"
android:versionName="1.1" >

<activity
android:name="com.linkedtalents.app.Splash"
android:theme="#style/AppBaseTheme"
android:screenOrientation="portrait"
android:configChanges="locale"

it seems that you are missing the intent filter. at least you didnt post it. can you have a look that you have the MAIN LAUNCHER like here? you need exactly one activity that matches this, if you want to be started from a homescreen.
<activity
android:name="..."
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>

Installing two apps using one apk

I have 2 apps:
1 - ContentProvider;
2 - Application that uses this ContentProvider.
I need to install these 2 apps using single apk file. I want to push these two apps simultaneously, in Eclipse if I add to buildpath of one app another project and add several lines in the manifest.Is it possible to install simultaneously two apps(one of them is ContentProvider) using one apk?
Is it possible to install simultaneously two apps(one of them is ContentProvider) using one apk?
No, sorry.
You may define multiple activitys, services etc in one manifest.xml. So if you were to move both of your applications into one project, and then add them both to the manifest, you can in a way install multiple apps in one apk.
Look here for more info about the manifest: http://developer.android.com/guide/topics/manifest/manifest-intro.html
However, as already pointed out, the application-tag can only occur once.
Yes it's possible to have two apps (internally activities) installed in one api.
Extending to dac2009's answer..
Here is one sample Manifest file that does this.
`<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.dualapp"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="19" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name_people"
android:theme="#style/AppTheme" >
<activity
android:name="com.example.dualapp.MeetPeopleActivity"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name_people"
android:taskAffinity="com.example.dualapp.MeetPeopleActivity" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.example.dualapp.MeetTechieActivity"
android:icon="#drawable/ic_tech"
android:label="#string/app_name_techie"
android:taskAffinity="com.example.dualapp.MeetTechieActivity" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>`
Installing this puts two app icons in my mobile.

Android app does not start (and is invisible!) on device

I have a strange problem with my Android app. When I start it from Netbeans, the app gets installed on my device (attached via USB). After that nothing happens. I also can't find the app anywhere on the device!! (no icon, no nothing).
Still I know the app has been installed, because under the android settings, where it says "Manage Applications" (or something) the app is now listed and I can uninstall it.
I've tried the whole procedure with a blank HelloWorld app, which worked fine. Here an icon got created o the device and the app was started correctly by NetBeans.
So I guess there is something wrong with my app causing it not to appear in the phone's launcher?
EDIT:
Here's the manifest:
<?xml version="1.0" encoding="utf-8"?>
<uses-sdk android:minSdkVersion="4" />
<application
android:icon="#drawable/icon"
android:label="#string/app_name" android:debuggable="true">
</application>
you need to add below line in your Main activity in androidmanifest file
<activity android:label="#string/app_name"
android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

My apps will not install on device when downloaded from the Android Market

I am unable to install my app onto a device even when it is downloaded from the Android Market. How can this be possible? If it were signed incorrectly wouldn't the market not accept it? I have tried to install it by isolating various activities but none seem to work even when I reduce it to a simple hello world application. The app has a tab view, two being webviews [one includes a reload button] and one tab that allows a user to send an email to a submission page. Does anyone have any ideas as to what I am missing?
Thank you all very much in advance.
EDIT:
It's being downloaded on the LG Ally running 2.2.2 and my app runs fine on an 2.2 emulator. It is compiled with a min level of 4. Here is my AndroidManifest file
<?xml version="1.0" encoding="utf-8"?>
<application android:icon="#drawable/icon" android:label="#string/app_name" android:debuggable="false">
<activity android:name=".BrotipsTabs"
android:label="Brotips">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".TabWidget"
android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar">
</activity>
<activity android:name=".Random"
android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar">
</activity>
<activity android:name=".Sub"
android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar">
</activity>
<activity android:name=".BrotipsTabs" android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar">
</activity>
<meta-data android:name="com.mobclix.APPLICATION_ID" android:value="<Key>"/>
<activity android:name="com.mobclix.android.sdk.MobclixBrowserActivity" android:theme="#android:style/Theme.Translucent.NoTitleBar"/>
</application>
<uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.READ_PHONE_STATE" /> <uses-permission
android:name="android.permission.ACCESS_NETWORK_STATE" />
</manifest>
By not working I mean it refuses to install and claims it never did while an icon remains on the phone.
Do you have any previous versions of your app installed on your phone? If you have an apk that is signed with the debug signature (which eclipse uses when you push run) and try to install it from the market which is signed with an actual signature then it will fail due to the two signatures being different. The message that it shows you is different on different devices I've found. If you have any previous versions of your app installed you should uninstall them and try to install from the market again. You should be good to go.

I'm also tackled with this same problem and finally I found the solution for it. When you creating a new android project using Eclipes and if you didn't create a activity for your first window, your project's Manifest also don't create proper codings for you to application launch up.
So, you should hardcode them yourself.
First check these codes are available or not in your Project's Manifest file, within your main activity tags.
**
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
**
These two code lines are very important. Because these two lines are calling to android OS to launch this app.
So, Make sure these codes are available in your project's Manifest file. If it's not this below Manifest file code will gets you rough idea to fix this problem.
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mershanfernando.testingappz"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="10" />
<application android:icon="#drawable/ic_launcher" android:label="#string/app_name">
<activity android:name=".Main"
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>
