Unsuccessfully installing an app on a Genesis GT-7240 tablet

I have a tablet Genesis GT-7240, whose Android version is 4.1.1, Kernel 3.0.36+.

Man manifest.xml has

<uses-sdk android:minSdkVersion="11" android:targetSdkVersion="17" />

I’m trying to run a simple application, which uses Google Maps and therefore the compilation has to be via Google API and not Android.

I compiled the application, marked on the tablet to accept unreliable sources, copied the APK to the download folder of the tablet, as I’ve done hundreds of times with other applications.

However, when installing the application, comes the message

X App not instalad

and there is no explanation of which error.

Other apps that are based on Google Maps also saw that they did not work happily, before.

Note: On another tablet, now a Samsung, works. And the version is 3.2.

  • Can you install, or the tablet has, Google Maps?

If your AndroidManifest.xml have permission ACCESS_FINE_LOCATION and the device does not have GPS (which seems to be the case of this tablet), will not install. The reason is simple: this permission is precisely the one that provides the GPS feature for the applications and therefore requires a GPS receiver to work.

  • Dear Piovezan, in my manifest.xml, in <permission I made no reference to the type of 'Provider'. Neither Fine nor Coarse, because the tutorial said nothing about it. And it works in version 3.2, on a more advanced tablet, which is Samsung.

The Google Maps API is not native to the Android OS, that is, it is not part of the core of Android and may not be available on this tablet.

This occurs mainly in models that are not approved by OHA and Google, and so for legal reasons can not put Google Maps on the device, and so it is not possible to install as it is an essential library for the application that is not installed on the tablet.

Even this is the reason you can install on Samsung device, which is approved and has Google Maps.

  • Neto Marin, you may have hit the nail on the head.

  • Thank you Mauro. Accept the reply then as correct :) thank you, hugs.

Here in the company I also use a Genesis Tablet for development (GT-1230), and I realized that these devices do not have multiple sensors, I’ve had problems trying to download apps in Google Play, for lack of sensors (hardware) and not by software version, check whether these Google API-based applications do not require any sensor that your Tablet may not have available.

Note: It may be something else, but in my experience it must be something connected to hardware, not software.

  • Dear Fernando, I’m really thinking about this, which is a hardware problem, as also the opinion of Piovezan friend, otherwise.
