My android app is not rotating. Where could the problem be? - java

Rotating can't seem to work in my app. I can't find where the problem is. If someone could help with that. At first it was working, but then I don't what changed in the code that made it stop rotating.If any classes other than the android manifest may contain the error please let me know in order to upload it Thank you.
Here is my AndroidManifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.how">
<!--

</application>
</manifest>


To use the user specified rotation, use this code:
activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_USER);


Please remove android:screenOrientation="portrait" in the manifest file otherwise add sensor instead of portrait.
Or in the whole Activity add android:screenOrientation="sensor" in the manifest

App is not compatible with TVs on closed testing in the Google Play. This item is not compatible with your device

I'm developing an app for Android TV and TV-boxes.
My problem is that Android TV devices are available for installing my app from Google Play for internal testing, but NOT available for closed testing (but it still can be installed on the smartphones).
Screenshot: Google Play install dialog
My app starting from StartScreenActivity (it's splash screen).
The QUERY_ALL_PACKAGES is required for my app and declared.
AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>

</manifest>
On the internal testing it works like expected, but no one can to install an app to TV on the close testing. Setting the android.software.leanback as required not helped - it just making all others devices not available for install.
What am I doing wrong? Please advise.

It was non-obvious, but all you need is to add Android TV form factor to the Google Play Console:
Release -> Advanced Settings -> Form Factors -> Add
How to add the form factor to the Play Console
I waited over 24 hours before my application was approved.
Now all TV devices are available.

Android Automotive: Could not identify launch activity: Default Activity not found

I have just created my first Android Automotive project:
when I run AndroidAutoDemo.mobile module it works fine:
Unfortunately when I switch to AndroidAutoDemo.automotive module I get:
Could not identify launch activity: Default Activity not found
Error while Launching activity
Failed to launch an application on all devices
This is the Android Manifest file in AndroidAutoDemo.automotive module (left as default):
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.androidautodemo">
<uses-feature
android:name="android.hardware.type.automotive"

android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/Theme.AndroidAutoDemo" />
</manifest>
This is my mobile emulator:
How can I fix?

To run automotive app you need Automotive emulator and Automotive flavor with Manifest like below. Also there is no Automotive emulator provided by Google yet but you can get other open source emulator from like Polestar https://developer.polestar.com/sdk/polestar2-sys-img.xml
and Volvo https://developer.volvocars.com/sdk/volvo-sys-img.xml
You don't have to add new activity
if want to understand you can go through example source code
https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:car/app/app-samples/helloworld/
`
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

</intent-filter>
<meta-data android:name="distractionOptimized" android:value="true"/>
</activity>
</application>
</manifest>
`

Each Manifest file should include information about available activities and launcher activity. Launcher activity needs to be defined with some additional Intent filters, for example:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.car">
<uses-permission android:name="android.car.permission.CAR_POWERTRAIN" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#android:style/Theme.DeviceDefault.NoActionBar">
<activity android:name="com.example.car.MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

Android App ist running on Device in USB-Debug-Mode but not after APK-Install

I am very new In Android Development and developed a "Time Stamp Clock - App" which reads NFC-Tags.
Everything fine, it is running on Device via USB-Debug-Mode without Errors as expected. When I build APK and install on the same Device, the installing is without errors, but after that, the open-button is grayed out and inactive and there is no desktop-icon to launch. In the APPS Overview it is displayed, but not able to open.
Can someone tell me, what can i do, to figure it out, what is going wrong there?
EDIT:

It is a simple structure in the app. LoginActivity as Start-Activity and a TabbedActivity for the NFC-Stuff.

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 !

My Device is HTC OneX
Android Version: 4.03
HTC Sense Version: 4.0
Software number: 1.29.110.11
HTC SDK API Level: 4.12
HTC Extension version: HTCExtension_403_1_GA_7
Please guide as I am new fish in Android Sea.
Edit-1:
I have noticed that if I comment this below line then application does deploy and execute but obviously I cant go forward without below mentioned permission ... please help....
<permission android:name="Android.Test.permission.C2D_MESSAGE" android:protectionLevel="signature" />

Change name package with Caps letters to little letters.

Change your
android:name="MainActivity"
TO
android:name=".MainActivity"
OR add the fully qualified package name in lowercase before your class name
android:name="thepackage.MainActivity"
Do change all the attributes named as android:name inside the activity tags as I suggested.

Instead of:
<permission android:name="android.permission.C2D_MESSAGE" android:protectionLevel="signature"/>
to:
<uses-permission android:name="android.permission.C2D_MESSAGE" android:protectionLevel="signature"/>
Try that.

<activity android:name="MainActivity"
should be formed like
<activity android:name="com.company.appname"
to do this without errors go to package (right click) > android tools > rename app package

try to write activity name follow by "."
Instead of
<activity android:name="MainActivity"
android:label="#string/app_name">
use
<activity android:name=".MainActivity"
android:label="#string/app_name">

I met this same issue in android studio
what solve this is to let company domain to be all small letters,

There's issue about this: http://code.google.com/p/android/issues/detail?id=37658
Capital letters can't be used in package names within permissions. You got (same as me) into difficult situation when you have deployed application with package name like this and you need to use GCM.
I tried to use some kind of short form of permission:
<permission android:name=".permission.C2D_MESSAGE" android:protectionLevel="signature" />
<uses-permission android:name=".permission.C2D_MESSAGE" />
I also defined service in the same way. It had to be in application package.
It worked on Android 4.3. Probably on 4.2 also. I know that on 4.0.3 it didn't.

make sure your package name is in small letters...
worked for me

write the java package name and all folders name in lowercase, it will work fine...

In my case I was mentioned the package name in small letters only. But for few of the activities I named it with partial name i.e android:name=".ContactUs" . After I solved it by prefixing full package name before all the activity name, service name and broadcast provider name in Manifest file.

I had this problem. My device memory was full. I solved my problem with freeing device memory.

For Android 12 (Android ", API Level 31) you can find this same error because of behavioural changes.
To get rid of it you must add android:exported="true" (or false*) to any <activity>, <activity-alias>,<service>, or <receiver> components that have <intent-filter>s declared in the app’s AndroidManifest.xml file.
