Hello.

I have a mobile phone that have this hardware:

Processor ARMv7 rev 9 (v71) 849Mhz

445MB ram.

Using Android OS v 4.0.4 (Ice Cream Sandwich)

I created a FireMonkey Mobile project, then, i put some edits and labels into my form and just run it.

(I already have did the configs to SDK/NDK)

My application compile ok, deploy ok, install ok, run ok. But when i see it running on the mobile device, i only see blank screen, i can click on the edits but it is all invisible, it works and show me the keyboard but i can't see anything , its all blank.

I need help with this, Embarcadero told me that ARMv7 is compatible processor, so i don't see the problem.

Please help.

Same here. I tried to test run a simple android compile with just a Tbutton on a form. When I debug run on my Galaxy S3 or xe5 emulator, I just get a blank screen.

Somebody in another thread found a partial solution:

Simply delete the app that was initially uploaded to the device and re-run (re-deploy) and it works.

While the application running on device, try to Lock and then Unlock. For me Worked.
I'm using a Xperia Play R800a (android 2.3.3).

On my virtual device, i don't have this problem.

I´m disapointed! Even a simple button on the form don´t works in rad studio xe5 for android! Get always this damage 'blank screen'. I´ve tried everything i know about the tablet itself and xe5. nothing work. If you got a solution please don´t forget to post here. My tablet is a Samsung Galaxy S3 Android 4.1.

I have the same problem with tablets. I'm test in Samsung Galaxy Tab 3 and Samsung Galaxy Tab P1000. In emulator and in a android phone the app works but in the tablets I always get a blank screen.

¿ Any know solution o patch ?

Thx,

Which Tab 3 are you using exactly?  I know of at least 3 models: SM-T210, 
SM-T211, and GT-P5210.  I don't know if the SM-T210 works, but XE5 prior 
to Update 2 has problems on SM-T211 (I don't know if Update 2 fixes it), 
and the GT-P5210 does not have an ARM CPU so it is not compatible with Delphi 
at all.

Refer to the compatibility list on the Delphi Wiki:

http://delphi.wikia.com/wiki/Android_Devices_Supported_for_Application_Development

You should add the Samsung Galaxy Tab P1000 to the list, as it is not listed 
yet.

The Galaxy Tab 3 is GT-P5220.

I think that the problem only affects to tablets, because in all "normal android phones" that i test it work good: Samsung Note II, Samsung Galaxy S4, Sony Xperia P, ...

The problem is present in XE5, XE5 update 1, XE5 update1 + hotfix and XE5 update 2.

I'll be waiting a solution , another hotfix or update ...

According to multiple sources I have found, including Wikipedia, Tablet Software, 
and SmartphoneZero, all the Galaxy Tab 3 10.1 models (GT-P5210 WiFi, GT-P5200 
3G, and GT-P5220 4G) have an Intel Atom CPU (specifically, the Z2560):

http://en.wikipedia.org/wiki/Samsung_Galaxy_Tab_series

http://tabletssoftware.blogspot.com/2013/05/samsung-galaxy-tab-3-with-intel-atom.html

http://www.smartphonezero.com/samsung-galaxy-tab-3-10-1-lte-gt-p5220-specs/

At this time, Delphi's mobile compilers do not support Intel mobile CPUs, 
only ARM CPUs.
