Android TV forces app in portrait mode

I have an Android mobile app and now I'm trying to run it on Android TV emulator, but it doesn't respond to screen orientation, it is always in portrait mode even though I handled it in code (it0s working both on mobile and tablet).. This is my AndroidManifest file:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="------">
<uses-permission android:name="android.permission.INTERNET" />

</application>
I also tried adding this line of code but it's not helping:
<uses-feature
android:name="android.hardware.screen.portrait"
android:required="false" />
Did you have similar experience or do you have any ideas what's the problem here?

I think it is not about your application orientation configurations. Many Android-tv producers force the orientation as landscape. If you have access, you may check system properties and find about x.forceorientation:landscape and change it.
Some producers have also put a settings menu option such as System Settings > Display > Rotate.
Another way, this application can work on some devices

I had the same problem but with a real TV device - the system ignored rotation at all (everything worked fine on tablets and phones).
I found solution for my case but it can be inappropriate for you.
So, the short answer is "impossible" the long answer goes here:
Firmware for TV devices often tweaked by their manufacturers, in my case it was /system/framework/services.jar
that contained services\com\android\server\wm\WindowManagerService.java
in which the following code handled the rotation case:
if ("box".equals(SystemProperties.get("ro.target.product", "tablet"))) {
rotation = 0;
}
of course the /system/build.prop has setting ro.target.product=box, when I tried to patch this file (I had root and possibility to reflash firmware) the system went into the kind of boot loop. The parameter ro.target.product was used several times inside system applications so I think that final firmware in my case lacks some additional code to handle other target modes. Because of this I was forced to patch classes.dex directly in order to turn this checking off.
Another set of options that controls rotation are persist.demo.hdmirotates and persist.demo.hdmirotation, by default they were turned off. When I added them via the command line:
setprop persist.demo.hdmirotates true
setprop persist.demo.hdmirotation landscape
I got desired behavior: my application chooses necessary orientation and it works! In my case the rotation of TV depends upon cabling requirements, i.e. the relative position of TV and its corresponding socket outlet on the wall.
So, no free lunch :-( each device should be handled separately.

Here Maps screen on Nokia X device shows a white screen with logo only

I have followed all steps mentioned in the porting guide for V1.

</activity>
I have added hardwareAcceleration to application tag as well.
It shows location markers properly without map tiles.
What could be the issuw. I am testing on a Nokia X device without SD card.
Any help would be appreciated.

the minSdkVersion should be also changed to be 11, you do need to set the Id & token to values reserved for you
As well as do add following permissions as well:
android.permission.WRITE_EXTERNAL_STORAGE
android.permission.ACCESS_WIFI_STATE
Also do try zooming out, could indeed be that you are located in a area which is shown in white and having full zoom there..
Basically it should be black if the initialization fails, and it should be blue if there is no tiles (or you are at sea), white background thus would indeed be inddicating something else going wrong.
Do also make sure you have enabled location, and have working mobile internet. Would also suggest opening HERE maps app, and downlaoding the maps tiles for the same location used in the app, thus you could see that how it is supposed to look like.

I have an android application which has a provision to controls calls ie, allow or block specific incoming & outgoing phone calls.Here is part of manifest file.

This application does not show for some devices in Google play.After a long time search I understood that it is due to <uses-feature> hardware requirements. No i want to remove the required hardware features for phone calls from manifest and check them from code.
Some tablets which does not have a Phone Call functionality does not show my application.So i want to make my application available to these tablets which lacks the required hardware.How can i achieve this?
Thanks in Advance

Some permissions automatically impy feature requirements.
This is what the API Guides says:
"For any of the permissions below, you can disable filtering based on the implied feature by explicitly declaring the implied feature explicitly, in a element, with an android:required="false" attribute."
Your permissions impliy the features android.hardware.wifi, android.hardware.location.network, android.hardware.location.gps, android.hardware.location and android.hardware.telephony.
You set only two of them to android:required="false". So you might try to set the other permissions to not required, too.

Unfortunately, there isn't a way to add permissions after the application is installed. Perhaps you can release 2 APKs. One for mobile devices and one for tablets.

Try this code to check if phone functionality is available :
public static boolean isTablet(Context context) {
TelephonyManager manager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
return manager.getPhoneType() == TelephonyManager.PHONE_TYPE_NONE;
}

Android app doesn't show up on tablet marketplace

I have been reading many questions on stackoverflow and I can't quite figure this problem out. I have an app that has a call feature but I still want tablets to access it. The app works on tablets if I manually install it via USB but it will not show up on the market place. I know that there are other questions regarding this issue but I am also asking if there are any other permissions I have that will not work on tablets.
Here is my manifest..
<uses-sdk
android:minSdkVersion="11"
android:targetSdkVersion="17"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" android:required="false"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
<uses-permission android:name="android.permission.CALL_PHONE"/>
<uses-feature android:name="android.hardware.telephony" android:required="false" />
<!-- External storage for caching. -->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<!-- My Location -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<!-- Maps API needs OpenGL ES 2.0. -->
<uses-feature
android:glEsVersion="0x00020000"
android:required="true"/>
<!-- End of copy. -->
<supports-screens android:smallScreens="true"
android:normalScreens="true"
android:largeScreens="true"
android:xlargeScreens="true"
android:anyDensity="true" />
I originally just had <uses-permission android:name="android.permission.CALL_PHONE"/>
But I recently added..
<uses-permission android:name="android.permission.CALL_PHONE"/>
<uses-feature android:name="android.hardware.telephony" android:required="false" />
Will this solve the problem of the tablet not being able to make calls and have it listed on the tablet marketplace?
Also, are there any other permissions that I have listed that I need to add android:required="false" to?
Also, this is how I am calling in the code...
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:" + markPhone));
startActivity(callIntent);

Change your code to call using ACTION_DIAL not ACTION_CALL:
try {
Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel:" + phoneNumber));
startActivity( intent );
} catch ( Exception e ) {
// no dialer activity found...
}
then you can completely remove these:
<uses-permission android:name="android.permission.CALL_PHONE"/>
<uses-feature android:name="android.hardware.telephony" android:required="false" />
from your Manifest, as your app is no longer need them.

Android Development: How to request permissions?

I was just wondering how to request permissions when creating an android application. I am a beginner, so please explain in simple terms :D.
So I want to make it so that my app can vibrate the phone at certain times, and the permission is called "android.permission.VIBRATE." But how do I request this? I do it in the Android Manifest file right?
Thanks for all help!

You're definately right. You need to put it in the AndroidManifest.XML
If you're using eclipse you can do it quite easily and without XML by opening up AndroidManifext.xml and use the Permissions tab at the bottom and press the "Add" button and selecting "Uses Permission" Then just select vibrate from the dropdown list.
If you want to do it in XML code you can add it before the application tag, like so:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="com.android.vending.BILLING" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:name="Application" >
(the rest of your manifest continues from here)
