Google Play store say my app is incompatible with device which I developed the app

sally3599 · Aug 18, 2012

The app is a example of Advanced Camera Library V1.00 from here

http://www.b4x.com/forum/additional-libraries-classes-official-updates/9383-advanced-camera-library-v1-00-a.html

Unexpectedly it said : This app is incompatible with your HUAWEI Ideos, and also it can't be searched in the Google Play !

I check the Device Availability on Developer Console, does this problem come from Screen layout?

Screen layout: SMALL NORMAL LARGE XLARGE
The device functions
android.hardware.camera
android.hardware.camera.autofocus
android.hardware.microphone
android.hardware.screen.landscape
android.hardware.touchscreen
android.hardware.wifi

Then I add supports-screens in the AndroidManifest.xml, the problem is not solved.

Here is my AndroidManifest.xml:

B4X:

<?xml version="1.0" encoding="utf-8"?>
<manifest
   xmlns:android="http://schemas.android.com/apk/res/android"
   package="camera.lite"
   android:versionCode="1"

   <supports-screens

       android:normalScreens="true"

   <application

      android:label="Camera Lite">
      <activity
         android:windowSoftInputMode="stateHidden"
         android:launchMode="singleTop"
         android:name=".main"
         android:label="Camera Lite"
         android:screenOrientation="landscape">
         <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
         </intent-filter>
         
      </activity>
      <service android:name=".httputils2service">
      </service>
      <receiver android:name=".httputils2service$httputils2service_BR">
      </receiver>
   </application>
</manifest>

Any help will be appreciate it.

Maybe because the device doesn't have a flash?

sally3599 · Aug 19, 2012

how many hour does google play store update the latest apk file?

Now I select this simple Camera app:

http://www.b4x.com/forum/basic4android-getting-started-tutorials/6891-take-pictures-internal-camera.html

But it still shows the device functions with camera.autofocus on Developer Console.

B4X:

android.hardware.camera
android.hardware.camera.autofocus
android.hardware.microphone
android.hardware.screen.landscape
android.hardware.touchscreen
android.hardware.wifi

Here is the AndroidManifest.xml:

B4X:

<?xml version="1.0" encoding="utf-8"?>
<manifest
   xmlns:android="http://schemas.android.com/apk/res/android"
   package="camera.lite"
   android:versionCode="1"
   android:versionName="1.0"
   android:installLocation="preferExternal">
   
   <uses-sdk android:minSdkVersion="4" android:targetSdkVersion="16" />
   <supports-screens android:largeScreens="true" 
       android:normalScreens="true" 
       android:smallScreens="true" 
       android:anyDensity="true"/>
   <uses-permission android:name="android.permission.CAMERA"/>
   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
   <uses-permission android:name="android.permission.INTERNET"/>
   <application
      android:icon="@drawable/icon"
      android:label="Camera Lite">
      <activity
         android:windowSoftInputMode="stateHidden"
         android:launchMode="singleTop"
         android:name=".main"
         android:label="Camera Lite"
         android:screenOrientation="landscape">
         <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
         </intent-filter>
         
      </activity>
      <service android:name=".httputils2service">
      </service>
      <receiver android:name=".httputils2service$httputils2service_BR">
      </receiver>
   </application>
</manifest>

and This app is incompatible with your HUAWEI Ideos too.
how many hour does google play store update the lates apk file after uploading?

Any help will be appreciate it.

Does your device support auto-focus?

Penko · Aug 19, 2012

Are you using the old copy protection? This makes compatibility troubles. Try disabling it.

sally3599 · Aug 19, 2012

Thanks for your help

I didn't use the copy protection, and HUAWEI Ideos not support flash and auto-focus, now I use the default Camera Library, has it flash and autofocus?
http://www.b4x.com/forum/basic4android-getting-started-tutorials/6891-take-pictures-internal-camera.html

Here is the AndroidManifest.xml shows only 3 permission:

B4X:

<?xml version="1.0" encoding="utf-8"?>
<manifest
   xmlns:android="http://schemas.android.com/apk/res/android"
   package="camera.litespace"
   android:versionCode="1"
   android:versionName="1.0"
   android:installLocation="preferExternal">
   
   <uses-sdk android:minSdkVersion="4" android:targetSdkVersion="16" />
   <supports-screens android:largeScreens="true" 
       android:normalScreens="true" 
       android:smallScreens="true" 
       android:anyDensity="true"/>
   <uses-permission android:name="android.permission.CAMERA"/>
   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
   <uses-permission android:name="android.permission.INTERNET"/>
   <application
      android:icon="@drawable/icon"
      android:label="Camera Lite">
      <activity
         android:windowSoftInputMode="stateHidden"
         android:launchMode="singleTop"
         android:name=".main"
         android:label="Camera Lite"
         android:screenOrientation="landscape">
         <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
         </intent-filter>
         
      </activity>
      <service android:name=".httputils2service">
      </service>
      <receiver android:name=".httputils2service$httputils2service_BR">
      </receiver>
   </application>
</manifest>

Then I upload this new app , it shows:

B4X:

The apk requirements the three kinds of permissions (application require these permissions will warn the user)

android.permission.CAMERA
android.permission.WRITE_EXTERNAL_STORAGE
android.permission.INTERNET

This apk file requires Google Play screening function 4 will be used to

android.hardware.camera
android.hardware.camera.autofocus
android.hardware.screen.landscape
android.hardware.touchscreen

On Supported devices of the Developer Console(Not Release Yet):

B4X:

Only when we have defined in the application manifest function of the device, in order to use this application.

The screen layout : SMALL the NORMAL LARGE XLARGE

The device functions
android.hardware.camera
android.hardware.camera.autofocus
android.hardware.screen.landscape
android.hardware.touchscreen

More than 0 kinds of mobile devices support this application.

Any help will be appreciate it.

Erel · Aug 19, 2012

The camera permission implicitly adds the focus and autofocus uses-features.
<uses-feature> | Android Developers

You can explicitly add these uses-features with required = false:

B4X:

AddManifestText(<uses-feature android:name="android.hardware.camera" android:required="false"/>
<uses-feature android:name="android.hardware.camera.autofocus" android:required="false"/>)

sally3599 · Aug 20, 2012

It works Now.

Thanks Erel.
It works.

Eduard · Mar 1, 2013

Thanks very much for this solution

Is there any way to get rid of the error the user would get if he/she tries to open the camera on a device that doesn't have a camera?

I tried

B4X:

   Try
      camEx.Initialize(Panel1, frontCamera, Me, "Camera1")
      frontCamera = camEx.Front
   Catch
      Msgbox("Some friendly message","")
      Activity.Finish
   End Try

But that doesn't work.

User still gets message: Error occurred. An error has occurred in sub; a_camera_initializcamera java line:818 java.lang.ClassCastException:java.lang.NoClassDefFoundError
Continue?

Erel · Mar 1, 2013

See the HasFeature method in this code: http://www.b4x.com/forum/134429-post4.html

You should check whether android.hardware.camera is supported.

Eduard · Mar 2, 2013

Thanks! That is exactly what I need.

Oswald · Apr 18, 2014

hi guys,
I am developing, debugging and testing my application with 3 different devices (v4.3, v4.0.3 and v.2.3.3) Everything is ok, works fine on all 3 devices. When I publish my application over the Google play, I can not find it with one of them which one has version 2.3.3. If try to reach that application over the web with the same device it says the application is incompatible with this device. what is wrong? if it is incompatible with that device how am I directly loading and runing APK file?

please help
BX

Erel · Apr 18, 2014

Greetings.

The link is invalid. Did a search on HasFeatures and could not come up with anything.

Best regards.

Thank you, Erel.

Where would I find a list of HasFeatures?

B4X:

HasFeature("android.hardware.telephony")

And on the flip side, if Google Play excludes devices I want included, I can add them in the developer console. Correct?

Best regards.

Sandy
