My app is incompatible with Google Nexus 4. Why? Here's my manifest (all of it except for <application/> part):
<uses-feature
android:name="android.hardware.location.gps"
android:required="false" />
<uses-feature
android:name="android.hardware.location"
android:required="false" />
<uses-feature
android:name="android.hardware.wifi"
android:required="false" />
<uses-feature
android:name="android.hardware.usb.host"
android:required="true" />
P. S. I've had reports that Samsung Galaxy S3 stopped detecting USB devices after updating to Jelly Bean. I wonder if it is related.
On the other hand, Nexus 10 also runs Jelly Bean and works perfectly.
<uses-feature
android:name="android.hardware.usb.host"
android:required="true" />
Set this to false and it should work. Not always, but generally usb hosts need to have the full USB port, not a micro one.

I received an email from a client saying one of our apps only installs on "some" chromebooks but not on the HP Chromebook 14 G5.
I checked https://sites.google.com/a/chromium.org/dev/chromium-os/chrome-os-systems-supporting-android-apps?visit_id=637873388265192668-2903345055&rd=1
Which states that this model supports Android apps. Our app uses the back camera for a qr code scanner and gps so I added these tags to the manifest
<uses-feature
android:name="android.hardware.touchscreen"
android:required="false" />
<uses-feature
android:name="android.hardware.camera"
android:required="false" />
<uses-feature
android:name="android.hardware.camera.any"
android:required="false" />
<uses-feature
android:name="android.hardware.location"
android:required="false" />
<uses-feature
android:name="android.hardware.location.gps"
android:required="false" />
<queries>
<package android:name="android.hardware.camera" />
</queries>
These tags allow the app to install on "some" chromebooks but not all. Im honestly at a bit of a loss how to diagnose this problem further? Possibly the client hasnt the most updated chrome os version?
Any other ideas or advice would be greatly appreciated.
I think the HP Chromebook 14 G5 does not have a GPS or the particular Chromebook does not have a GPS driver installed. The fact that you have that android:required="false" made it show up in the list of supported apps.
I am building a Xamarin Android App targeting the Amazon FireTV. When I upload the signed apk to the
Amazon developer portal and review the supported devices list, I get the following message
for all Fire TV hardware:
Your APK manifest requires capabilities not present on this device:
android.hardware.touchscreen
Understandably the FireTV hardware does not support touch, so removing this capability seems reasonable. All other hardware devices are supported.
I can deploy and run the app just fine locally via adb, so the app itself has no problem running on the FireTV hardware.
At present, I have included the following within the manifest file in hopes of a different outcome, but to no avail:
<uses-feature android:name="android.hardware.touchscreen" android:required="false" />
<uses-feature android:name="android.hardware.faketouch" android:required="true" />
<uses-feature android:name="android.software.leanback" android:required="true" />
Is there anything else I can try to address this "touch screen feature" issue?
I believe the problem is because you have android.software.leanback required set to true. Amazon Fire TV devices don't necessarily have the lean back feature installed or set, unlike Android TV specific devices.
A complete list of features I have that will allow the app to run on Fire TV and Android TV devices (and any device that supports the TV feature):
<uses-feature
android:name="android.hardware.touchscreen"
android:required="false"/>
<uses-feature
android:name="android.hardware.faketouch"
android:required="false"/>
<uses-feature
android:name="android.hardware.telephony"
android:required="false"/>
<uses-feature
android:name="android.hardware.camera"
android:required="false"/>
<uses-feature
android:name="android.hardware.nfc"
android:required="false"/>
<uses-feature
android:name="android.hardware.location.gps"
android:required="false"/>
<uses-feature
android:name="android.hardware.microphone"
android:required="false"/>
<uses-feature
android:name="android.hardware.sensor"
android:required="false"/>
<uses-feature
android:name="android.software.leanback"
android:required="false"/>
<uses-feature
android:name="android.hardware.type.television"
android:required="true"/>
<uses-feature
android:name="android.software.leanback_only"
android:required="false"/>
If you want it to run on devices with out the android.hardware.type.television (such as tablets) just remove that feature from the manifest entry. Otherwise it will restrict it to TV devices. I use the above settings in my production Android TV and Fire TV application.
In the Google Play Developer Console I can check which devices are compatible/supported for my APK. How do I find out why a device is unsupported?
For example, the Google Nexus 7 "tilapia" and "grouper" are not supported. But Nexus 7, Google Nexus 7 "deb" and Google Nexus 7 "flo" are supported.
Is there a way to know which feature in the manifest is causing the problem?
Features:
android.hardware.CAMERA
android.hardware.LOCATION
android.hardware.location.GPS
android.hardware.location.NETWORK
android.hardware.screen.LANDSCAPE
android.hardware.TOUCHSCREEN
API Level 10+
On AndroidManifest.xml:
<uses-permission
android:name="android.permission.CAMERA"
android:required="false"/>
<uses-feature
android:name="android.hardware.camera"
android:required="false"/>
<uses-feature
android:name="android.hardware.camera.front"
android:required="false"/>
<uses-feature
android:name="android.hardware.camera.autofocus"
android:required="false"/>
This should help. By default, declared permission are required. Nexus 7 (2012) doesn't have front camera, that's why this device isn't compatible.
http://developer.android.com/distribute/googleplay/quality/tablet.html#hardware-requirements
I think it is due to the lack of a rear camera on older nexus 7s. The tilapia and grouper are the 2012 version and have no rear camera (only front camera), flo is 2013 and has both types of camera.
I am developing an application and my application is installed and tested successfully on emulator and lots of devices like Asus eee pad, Galaxy tab, Galaxy note, HTC …
But I can not install it on Pidion BM-170 with android 2.3.7 and get error "Application not installed"
I tested other applications on this device and they are installed successfully. So the problem is about my application and this Pidion device.
I have signed my application.
I have tested putting android:installLocation="auto" in manifest.
I have tested Debuggable=false and true in manifest.
There is no previous application on device.
But I still get error "Application not installed".
I use these features in my application
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.SEND_SMS" />
<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
Why I get this error? How can I solve it?
Perhaps that device does not have the Google Maps SDK add-on library. After all, according to the device manufacturer, it does not even have Android normally -- it is described as "optional". They probably did not license the Google commercial apps, such as Play Store, YouTube, Google Maps, etc. If so, you cannot write apps that rely upon the Google Maps SDK add-on library that will run on that device.
I have added these permissions in the android market place.
<!-- Camera -->
<!-- Required to be able to access the camera device. -->
<uses-permission android:name="android.permission.CAMERA"/>
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" android:required="false" />
and then i have uploaded the app to Android Market. But my is not visible in the Android 4.0.3 tablet market. But visible in Android HoneyComb market place.
Minsdkversion: 12
Target : 12
Is any thing that i made mistake???
The target sdk version should always be the highest available. So use the 4.1 sdk and set target to 16.
